When it comes to women’s hygiene products, sanitary pads and pantyliners are two common options. Although they are all designed to provide comfort and protection for women during menstruation, they differ in shape, thickness, material and method of use. Here are the main differences between sanitary pads and pantyliners.

Shape and size:

Thickness:

Absorptive capacity:

Pantyliners are usually designed to absorb lighter flows and therefore have less absorption capacity.

Materials:
Sanitary napkins usually use a soft pulp or absorbent layer, and an outer layer of leak-proof material.
Pantyliners are usually made of thin cotton or synthetic fiber materials to provide thinner feel and better air permeability.

How to use:
Sanitary napkins are used to attach to underwear and usually have a wing-like structure to provide better side protection and prevent side leakage.
The pantyliner are also attached to the underwear, but because of their thinner characteristics, they usually do not have a wing-like structure.

When choosing sanitary napkins or pantyliners, you can choose according to your personal preferences and needs. If you have a heavy flow during your period, you can choose a sanitary napkin with higher absorption capacity. For lighter flows or late-cycle phases, pantyliners may be more suitable for you. In addition, for people with more sensitive skin, it may be more appropriate to choose products made of natural materials.

The idea of swapping R404A with R134A may sound simple, but it's not that straightforward. These two refrigerants have different properties and are designed for different types of systems, so just replacing one with the other isn't recommended.

What’s the Difference Between R404A and R134A?

R404A is a blend of gases mainly used in low-temperature systems, like freezers and refrigerated trucks. It has a high GWP (Global Warming Potential), making it a target for phase-out due to environmental concerns.

R134A, on the other hand, is used in medium-temperature systems, like air conditioners and refrigerators. It has a lower GWP than R404A, but it still contributes to global warming, so it's not a perfect solution either.

Why You Can't Just Swap Them？

Temperature Range

R404A works well in systems that require very low temperatures, while R134A performs better in moderate temperature environments. Swapping them could lead to poor cooling performance.

Pressure Differences

R404A operates at higher pressures than R134A. If you switch refrigerants, the system might not work properly, and you could risk damaging parts like the compressor.

Lubricant Compatibility

The oils used in refrigeration systems are tailored to the refrigerant. If you change from R404A to R134A, you may need to replace or flush the oil, as they are not always compatible.

Can You Convert the System?

Technically, you can convert a system, but it requires replacing or adjusting key components like the compressor, expansion valve, and lubricants. It’s not a simple or cheap process.

The Environmental Aspect

While R134A is better for the environment than R404A, it still has a high GWP. More eco-friendly options like R32 or R1234yf are available and becoming more popular as replacements.

Conclusion

In short, you can’t just replace R404A with R134A without modifying your system. If you're aiming for a more eco-friendly refrigerant, it might be better to explore newer alternatives with lower environmental impact. Always consult a professional if you're considering a refrigerant change.

When it comes to air conditioning and refrigeration, the term "refrigerant" often pops up. But among the many refrigerants used, R32 is becoming increasingly popular. So, what exactly is R32, and why is it causing such a buzz in the industry?

R32: A Modern Refrigerant

R32 is a type of refrigerant gas used in air conditioning and refrigeration systems. Technically, it’s a hydrofluorocarbon (HFC), which is a chemical compound that helps transfer heat efficiently. But more specifically, R32 is known for being a low global warming potential (GWP) gas compared to older refrigerants, like R22 or R410A.

What's the Difference Between R32 and Freon Gas?

You might have heard of "Freon," a term commonly used to refer to refrigerant gases. However, “Freon” is actually a brand name and has historically referred to various types of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). While Freon was once the go-to refrigerant for cooling systems, it's now being phased out due to its harmful effects on the ozone layer.

R32, on the other hand, is much more environmentally friendly. It has one-third the global warming potential of R410A, which makes it a step toward reducing the carbon footprint of cooling systems. So, when people refer to “Freon gas” nowadays, they’re often thinking of older refrigerants, whereas R32 is a modern, safer alternative.

Why Is R32 Gaining Popularity?

Environmental Benefits: One of the most significant reasons R32 is gaining traction is its lower GWP. Unlike Freon-based gases, R32 doesn’t contribute as heavily to global warming, making it a much cleaner choice for the planet.

Energy Efficiency: R32 is more energy-efficient, meaning it can cool your space faster and with less energy. This translates into lower electricity bills and less environmental impact.

Better Performance: R32 has a higher cooling capacity than some older refrigerants, which means it can do the same job with less refrigerant. It’s a win-win for both performance and sustainability.

R32 in Practice

R32 is most commonly found in modern air conditioners and heat pumps. If you’re in the market for a new cooling system, there’s a good chance that R32 is the refrigerant used. It's also easier to handle and recycle compared to older gases, which makes the transition to R32 smoother for manufacturers and technicians alike.

The Bottom Line

To sum it up: R32 is a more eco-friendly, energy-efficient alternative to older refrigerants like Freon. It’s the go-to refrigerant for newer air conditioning systems, with lower environmental impact, better performance, and improved energy efficiency. So, if you want a cooler home with a smaller carbon footprint, R32 might be your best bet!

Whether you're a tech enthusiast or simply looking to stay informed about the world of cooling, understanding R32 and its benefits is key to making smart, sustainable choices in today’s world.

    UUPAC's 14-Head 5L Computer Weigher is built specifically to meet these needs, with a design tailored to the unique challenges of weighing light, bulky, or even small granular food items. This guide breaks down how this model solves food packaging pain points, and why it's a reliable choice for factories focused on safety, efficiency, and compliance.

Why Food Factories Need a Weigher for "Light & Bulky" Products

Many food multihead weighers are designed for small, dense items (e.g., candy, spices)—but factories handling bulky or lightweight food (like large nuts, whole vegetables, or fresh salads) face distinct challenges:

• Bulky products (e.g., large almonds, bell pepper slices) need roomy hoppers to avoid jamming, but small-hopper weighers cause frequent downtime.
• Lightweight items (e.g., leafy greens, puffed snacks) are hard to weigh accurately—even slight air currents or uneven distribution can throw off measurements.
• Fresh or moist foods (e.g., salads, cut veggies) require easy cleaning to prevent bacterial growth, but many weighers have hard-to-reach crevices that trap residue.

    A mismatched weigher leads to costly issues: A salad factory using a small-hopper model might lose 15% of daily output to jams; a nut packer with low accuracy could waste $400+ monthly on overpacked bags. UUPAC's 14-Head 5L Computer Weigher solves these problems with features built for light, bulky food.

1. Hygiene: Built for Fresh Food—Easy to Clean, No Hidden Risks

    For food like salads, fresh vegetables, or moist nuts, hygiene isn't just a "checklist ite"—it's critical to preventing spoilage and meeting safety standards (e.g., FDA, EU 10/2011). The 14-Head 5L Weigher's design eliminates contamination risks:

Food-Grade Materials & IP65 Waterproof Rating

• All food-contacting parts (including the 5L hoppers) are made of SUS 304 stainless steel—non-porous, corrosion-resistant, and compliant with global food contact regulations (FDA 21 CFR §177.2600, EU 1935/2004). It won’t leach chemicals into food, even when exposed to moisture from fresh produce.
• IP65 waterproof design lets you rinse the entire machine (hoppers, control panel cover, and frame) with high-pressure water after shifts—no need to disassemble parts to clean hidden gaps.

Fully Open Hoppers for Thorough Sanitization

    Unlike weighers with closed or hard-to-reach hoppers, the 14-Head 5L model’s 5L hoppers can stay fully open during cleaning. This means no trapped lettuce leaves, nut crumbs, or vegetable juice—reducing the risk of mold growth and cutting cleaning time by 30% (vs. traditional closed-hopper models).

2. Accuracy: ±0.1g Precision for Both Bulky & Small Granular Food

    Whether you're weighing 5000g bags of mixed nuts (bulky) or 100g portions of Chinese medicine tablets (small granular), accuracy directly impacts your bottom line. The 14-Head 5L Weigher delivers consistent precision for all food types:

High-Standard Load Cells & Multi-Segment Calibration

• Equipped with special high-precision load cells (meeting OIML III standards), it achieves an accuracy of ±0.1g and a minimum scale interval of 0.1g. For a nut factory packing 20,000 1000g bags daily, this means:

• No more 5g overpacks (which waste 100kg of nuts monthly, costing $300+ at $3/kg).
• No underpacks that risk regulatory fines (e.g., EU penalties for mislabeled weight).

• Multi-segment weight calibration lets you pre-set parameters for 3–5 different food types (e.g., large nuts, small tea leaves, fresh salads). Switch between products with one tap on the touchscreen—no manual recalibration needed, even when moving from bulky to lightweight items.

Anti-Noise PVC for Stable Weighing

    Material-contacting parts are lined with anti-noise PVC, which reduces vibration and interference from lightweight or fluffy foods (e.g., puffed snacks, leafy greens). This ensures stable measurements, even in busy production environments where machinery vibration might throw off less robust weighers.

3. Compliance: Features to Simplify Audits & Record-Keeping

    Food safety regulations require detailed production records—especially for products sold globally. The 14-Head 5L Weigher includes tools to make compliance stress-free:

Batch Data Logging & Authority Management

• It automatically logs batch numbers, production times, target weights, and actual portion weights (with timestamps). You can export this data to a USB drive or sync it with your factory's ERP system—so if auditors ask for proof of consistent portioning, you don't have to rely on paper logs.
• The HMI program includes different authority management (e.g., operator, supervisor, admin roles), ensuring only authorized staff can adjust weighing parameters. This prevents accidental changes that could lead to non-compliant portions, and creates a clear audit trail of who made adjustments and when.

Traceable Components & Certifications

    All parts of the 14-Head 5L Weigher (from load cells to stainless steel hoppers) come with certification documents (material safety data sheets, calibration certificates). This proves your equipment meets global food safety standards—critical for selling to strict markets like the EU, Japan, or the U.S.

Why the 14-Head 5L Weigher Is Perfect for Your Food Line

    This model shines for food manufacturers dealing with diverse or bulky products—here’s who it’s ideal for:

• Nut & Seed Processors: Weigh large-sized nuts (e.g., walnuts, almonds) or small seeds (e.g., sunflower seeds) without switching equipment.
• Fresh Food Factories: Package salads, cut vegetables, or fruit mixes—IP65 waterproof design handles frequent cleaning, and large hoppers avoid jams.
• Specialty Food Brands: Weigh small-batch items like Chinese medicine tablets, premium tea, or artisanal chocolate beans—99 preset programs support quick SKU changes.

• Are You Affected by the "Hidden Costs" in the Packaging Process?

    Food factories suffer from production line congestion due to slow manual packaging speeds, sauce enterprises face material leakage and loss caused by poor sealing, and the monthly labor cost of small and medium-sized factories accounts for more than 30%... The core of these problems often lies in the "automation gap" in the packaging process.

    As a Chinese manufacturer with 10 years of experience in packaging equipment, UUPAC's Rotary Vacuum Bag Feeding Packaging Machine has become the choice for many enterprises to upgrade their production lines with its three core capabilities: "cost reduction, efficiency improvement, and compliance".



• 2 Sets of Data Tell You: Why Automated Packaging Is a Must?

1. Loss Control Calculation: Manual packaging is prone to 1%-3% waste of bag materials due to operational errors, while the equipment's automatic monitoring system can control the loss rate within 0.1%, reducing material loss by tens of thousands of yuan annually (based on a bag cost of 0.5 yuan and an annual output of 1 million bags).​

2. Compliance Risk Calculation: In the food industry, microbial exceeding standards caused by manual contact with packaging may lead to unqualified quality inspections, with fines reaching 20%-50% of the value of the production batch. UUPAC equipment's fully automated process and food-grade stainless steel materials avoid such compliance risks from the source.

 

• UUPAC Rotary Vacuum Bag Feeding Packaging Machine: 5 Core Advantages to Address Production Pain Points

1. Efficiency Revolution: "1 Person Equals 10 People"​

• Efficiency comparison: Traditional manual packaging is limited by physical strength and concentration, with large efficiency fluctuations and an obvious upper limit. However, the UUPAC equipment only requires one person to be responsible for replenishing packaging bags into the bag magazine, and it can achieve stable and efficient continuous output. The output per person is greatly improved, which can significantly reduce the number of required workers and reduce the scheduling pressure.​
• Applicable scenarios: It is especially suitable for industries that require continuous production such as food and daily necessities - whether it is the bulk packaging of meat processing plants or the multi-shift production of washing powder factories, it can break through the bottleneck of manual efficiency through "less human involvement" operation.​
• Principle: The bag magazine can hold hundreds of bags at one time, and the equipment automatically completes the entire process of "bag grabbing → opening → filling → sealing" without manual intervention in the intermediate links, avoiding efficiency losses such as pauses and errors in manual operations.​

 

2. Multi-Scenario Compatibility, No More "Equipment Idle"​

• Adaptable bag types: flat bags, stand-up bags, zipper bags, paper bags (TY-RVP200 model), covering multiple categories such as food (meat, snacks), daily necessities (washing powder), and chemical products (detergents).​
• Flexible switching: When changing packaging specifications, the equipment automatically adjusts the bag width, reducing changeover time from 30 minutes to 5 minutes, meeting the needs of multi-batch and small-batch production.

 

3. Intelligent Error Prevention, Controlling Every Penny of Cost​

• Automatically detect faults such as abnormal air pressure and unopened bag mouths, stop and alarm immediately to prevent unqualified packaging from flowing to the next step; do not seal when there is no material, and empty bags can be reused, which greatly saves costs.

 

4. Food-Grade Compliance: Materials and Processes for Safe Packaging​

    Parts in contact with products are made of SSUS304 stainless steel, which is acid and alkali resistant and easy to clean; the vacuum chamber can be disassembled and disinfected separately, meeting food safety production standards such as FDA and HACCP, making it particularly suitable for high-standard industries such as meat and aquatic products.

 

5. "User-Friendly" Operation, No Professional Technicians Required​

    Equipped with a PLC+POD electronic control system, key parameters such as heat-sealing temperature and filling volume can be adjusted with one click via an intuitive human-machine interface, featuring clear and easy-to-understand operation logic; no professional technical background is needed, and ordinary employees can quickly master it after simple guidance, significantly reducing reliance on professional technicians.

 

• How to Choose the Right Model for You? Understand Parameter Comparison in 2 Minutes​

Demand Scenario	Recommended Model	Core Advantages
Medium capacity (30-50 bags/minute), regular bag types	TY-RP200	Cost-effective, suitable for start-up food factories
High capacity (50 bags/minute), need to be compatible with paper bags	TY-RVP200	Faster speed, suitable for more special bag types

 

• Packaging Automation Is Not a "Choice" but a "Survival Issue"

    In today's era of rising labor costs and increasing consumer requirements for packaging quality, choosing a packaging equipment that can balance efficiency, cost and compliance is no longer a question of "whether to upgrade" but "how to upgrade quickly". As a Chinese local manufacturer, UUPAC not only provides cost-effective equipment but also can customize solutions according to your production line - consult now to turn your packaging link from a "cost center" into a "profit growth point".

    For manufacturers in food, pharmaceuticals, hardware, or consumer goods, selecting a multihead weighed that matches your production capacity isn't just about "picking a fast machine"—it's about balancing speed, accuracy, space, and cost to avoid overinvesting in unused capacity or struggling with bottlenecks. UUPAC's multihead weigher category offers models ranging from compact 4-head units to high-capacity 10-head systems, each designed for specific output needs. This guide will help you identify which model aligns with your daily production goals, product type, and facility constraints.

Step 1: Calculate Your Actual Production Capacity Needs

    Before browsing UUPAC's multihead weigher lineup, start with a clear number: how many weighments do you need per minute (WPM)? This depends on two key factors:

1. Your daily production target (e.g., 50,000 packaged units per 8-hour shift).
2. Your packaging machine speed (e.g., a VFFS machine that seals 60 bags per minute—your weigher must match or exceed this to avoid bottlenecks).

    Once you have your WPM, use UUPAC's model range to narrow down options—we've grouped our multihead weighers by "capacity tiers" to simplify your choice.

Step 2: Match Your WPM to UUPAC's Multihead Weigher Tiers

    UUPAC's multihead weigher category is designed to cover three core production scenarios: small-batch/mid-volume, high-volume, and specialized high-capacity operations. Below is how to align each tier with your needs, plus key model recommendations from our category page.

• Space Fit: Dimensions of 1,086(L)X710(W)X898(H)mm and 91kg net weight—fits under low ceilings or beside existing packaging lines.
• Why It Works: The 4-head design balances speed and simplicity; it's easy to clean (IP65 waterproof) and supports quick product changeovers (99 preset programs) for brands with 5–10 SKUs.

• Tier 2: High-Volume Operations (60–120 WPM)

• Who This Is For:

• Medium-to-large food manufacturers (e.g., cereal producers, bulk nut packagers, frozen food facilities).
• Businesses with consistent high output (40,000–80,000 units per 8-hour shift).
• Product types: Medium-to-large volume items (50–1,000g), such as granola, rice, dried fruit, or herbal medicine slices.

• Key UUPAC Models: 10-Head 1.6L/2.5L Computer Weighers (TY-A-M/P10-16 / TY-A-M/P10-25)

    These are the workhorses of UUPAC's multihead weigher category, designed for reliable high-volume performance:

• Speed: Up to 60 WPM (1.6L) and 60 WPM (2.5L)—with 10 independent hoppers that combine weights to hit target measurements in seconds (adds flexibility for variable product sizes).
• Capacity: 1.6L hoppers (max 1,000g per hopper) for medium items; 2.5L hoppers (max 1,500g per hopper) for larger, denser products (e.g., whole almonds, pasta).
• Accuracy: ±0.1g error margin—critical for pre-portioned products sold by weight (avoids regulatory fines for underpacking or material waste from overpacking).
• Why It Works: The 10-head design handles peak production periods without slowdowns; it also supports blended product weighing (e.g., mixed nuts) and integrates seamlessly with high-speed packaging lines (e.g., automatic pouch fillers).

• Tier 3: Specialized High-Capacity Operations (100–150+ WPM)

• Who This Is For:

• Large-scale industrial manufacturers (e.g., global snack brands, bulk chemical producers).
• Facilities with 24/7 production lines or ultra-high daily targets (80,000+ units per shift).
• Product types: High-density or large-volume items (1kg–5kg), such as industrial hardware, large bags of fertilizer, or bulk pet food.

• Key UUPAC Models: Custom 12–16 Head Multihead Weighers (Inquire via Category Page)

    For operations that need more than 10 heads, UUPAC offers custom-configured multihead weighers (available to quote via our multihead weigher category page):

• Durability: SUS 316 stainless steel construction (resists corrosion for chemical or wet products) and industrial-grade load cells (handles constant use without accuracy drift).
• Why It Works: Customizable to your exact line—we'll match the weigher's speed to your packaging machine, add extra hoppers for blended products, or integrate with your factory's IoT system for real-time production tracking.

• Step 3: Avoid Common Capacity Mistakes

Even if you pick the right WPM tier, these errors can ruin your investment—here's how to avoid them:

1. Don't Overbuy for "Future Growth":

A 16-head weigher is unnecessary if you only need 60 WPM today. UUPAC's multihead weigher category includes modular models (e.g., the 10-Head 1.6L) that can be upgraded with extra hoppers later—save money now and scale when needed.

2. Don't Ignore Product Density:

A 4-head weigher might hit 85 WPM for lightweight candy, but it will slow down for dense products (e.g., metal bolts). For heavy items, opt for larger hoppers (e.g., 2.5L instead of 0.5L) to reduce the number of "refills" per weighment.

3. Match Weigher Speed to Your Slowest Machine:

Your weigher can't fix a slow packaging machine. If your VFFS machine only does 50 WPM, a 120 WPM weigher will sit idle—use UUPAC's category page to filter models by speed that aligns with your existing equipment.

    Now that you know how to match capacity to your needs, if you're still unsure, contact our team with your daily production target and product type—we'll recommend a model that fits your capacity, space, and budget.

    In the competitive landscape of manufacturing and packaging, precision, speed, and reliability in weighing processes directly impact your production efficiency. Whether you're handling food items, pharmaceuticals, hardware components, or chemical products, the right weighing equipment can streamline operations, reduce waste, and ensure consistent quality.

    If you're looking to enhance efficiency, reduce waste, and ensure precision in your weighing processes, the UUPAC High-Capacity 10-Head Computer Weigher is the solution you've been searching for. Contact us today to learn how it can integrate seamlessly into your production line and drive your business forward.

    In today's fast-paced manufacturing and packaging sectors, small to mid-sized production facilities face a unique challenge: balancing efficiency, precision, and cost-effectiveness. Oversized weighing equipment can waste floor space and stretch budgets, while low-capacity options struggle to keep up with daily output goals. For food processors, snack manufacturers, and small-batch producers, the right linear weigher needs to be space-saving, reliable, and adaptable—and that's exactly what the UUPAC 4-Head 0.5L High-Speed Linear Weigher delivers.

Why Linear Weighers Stand Out for Mid-Volume Operations?

1. Operate in compact facilities (e.g., small-scale snack factories, local food processors) and need equipment that fits tight floor plans.

2. Handle diverse products (from granular items like nuts or spices to small pieces like candy or pet treats) and require quick recipe switches.

3. Seek cost-effective automation—linear weighers integrate seamlessly with existing equipment (VFFS machines, pouch fillers, jar fillers) without the investment of a full-scale production line overhaul.

    The UUPAC 4-Head 0.5L model takes these advantages further, addressing common pain points like inconsistent weight accuracy, slow changeovers, and difficult maintenance.

Key Features: Built for Practicality and Performance

     What makes this linear weigher a top choice for mid-volume producers? Its design prioritizes ease of use, durability, and flexibility—all critical for keeping production lines running smoothly.

1. Compact Design, Maximum Space Efficiency

    With a net weight of just 91kg and dimensions of 1,086(L)X710(W)X898(H)mm, this weigher fits into tight production spaces (e.g., small workshops or existing lines with limited room). The 0.5L small-volume hoppers don't just save space—they also boost precision by reducing product residue and ensuring consistent dosing for lightweight items (3–300g).

2. Reliable Accuracy for Compliance and Waste Reduction

    Equipped with a minimum scale interval of 0.1g and accuracy class X(0.5), this weigher eliminates the risk of underpacking (which risks regulatory fines) or overpacking (which wastes materials). For food processors selling pre-portioned snacks or powdered goods, this level of precision directly protects profit margins.

3. Blended Product Weighing: Versatility for Multi-SKU Lines

    One of its most valuable features is the ability to handle 4 types of blended products (e.g., mixed nuts, trail mix, or multi-flavor candy). Simply set up the recipe in the system, and the weigher automatically combines products to the required total weight—no manual mixing or separate weighing steps needed. This is a game-changer for brands offering custom or mixed SKUs.

4. User-Friendly Operation and Quick Changeovers

• The 7 "color touch screen (with intuitive controls) lets workers switch between 99 preset product parameters in minutes—ideal for facilities running multiple SKUs.
• Amplitude adjusts automatically, so there's no need for time-consuming manual tweaks when changing products (e.g., from fine sugar to larger cereal pieces).
• Software can be upgraded via USB, ensuring the weigher stays compatible with future production needs without costly hardware replacements.

5. Durability and Easy Maintenance for Long-Term Value

• Constructed with SUS 304/316 stainless steel (optional) and an IP65 waterproof design, it's easy to clean—critical for food, pharmaceutical, or cosmetic applications where hygiene compliance is mandatory.
•  The modular control system simplifies repairs: if a component needs replacement, you won't have to shut down the entire machine. Factory parameter recovery also minimizes downtime if settings are accidentally changed.

6. Stable, High-Speed Performance

    Driven by a step motor with an open-close mode, the weigher operates at a maximum speed of 85 weighments per minute (WPM)—fast enough to keep up with mid-volume production goals (e.g., 5,000+ packages per hour) while maintaining stability. It integrates seamlessly with VFFS machines, pouch fillers, and inline jar fillers, making it a flexible add-on to your existing setup.

Ideal Applications: Where This Weigher Adds the Most Value

    The UUPAC 4-Head 0.5L Linear Weigher is designed to solve problems across multiple mid-volume industries:

• Food & Beverage: Weighing snacks (chips, candy), grains (quinoa, rice), spices, or powdered drinks.
• Pet Food: Portioning small-batch dry pet treats or mixed kibble blends.
• Pharmaceuticals: Dosing small herbal tablets or powdered supplements (with SUS 316 stainless steel for compliance).
• Hardware & Electronics: Weighing tiny components like screws, washers, or connectors for small-package sales.

In the processing and sales of beans, insect-damaged beans have always been a “persistent problem” that affects quality and brand reputation. They not only damage the appearance and reduce consumer trust but may also compromise the storage safety of the entire batch. How can producers efficiently remove insect-damaged beans and enhance product quality? The answer is — Ai Bean Color Sorter.

Why Traditional Bean Color Sorters Fail to Remove Insect-Damaged Beans

Older generations of color sorters mainly rely on simple color differences to perform sorting.

• Minimal color difference: Many insect-damaged beans retain a normal appearance, with only small spots or tiny holes, which conventional machines struggle to detect.

• Hidden damage: Some insect damage occurs inside the bean, causing only subtle surface changes that traditional sorters often miss.

• Single recognition method: Early machines simulated the human eye with basic optical detection, lacking the ability to judge fine textures, dark spots, or surface defects.

This leads to a common issue: traditional color sorters can remove obviously defective beans, but fail to thoroughly eliminate insect-damaged beans.

Advantages of Smart Bean Color Sorter for Insect-Damaged Bean Removal

With advanced multi-spectral imaging and intelligent algorithms, the new generation of bean color sorters breaks through these limitations:

• High-definition detection: Captures subtle dark spots, holes, and color variations on the bean’s surface.

• Intelligent learning: Built-in AI continuously learns insect-damage patterns, improving accuracy.

• Efficient rejection: High-speed precision air-jet separation removes defective beans instantly.

• Better product quality: Sorted beans are fuller, more uniform in color, and meet the demands of premium markets.

Bean Sorting Machine for Multiple Types of Beans

Whether soybeans, mung beans, red beans, kidney beans, or cowpeas — the smart color sorter handles them all with ease.

• One machine for multiple bean types

• Simple, intuitive interface

• Saves labor cost and boosts efficiency
