What is Box-Type Weight Sorter & How It Works
1)What Is a Box-Type Weight Sorter?
A box-type weight sorter (also called box-type weight sorting machine) is a high-precision automatic grading machine designed for food processing lines. It uses advanced weighing sensors to sort products into different weight grades automatically, with high accuracy and efficiency.
It is widely used for seafood, poultry, meat, fruit, nuts, and frozen food — any product that needs consistent weight classification.
Main Components
● Stainless steel 304 frame (food-grade, waterproof, easy to clean)
● Precision weighing sensor (high-speed dynamic weighing)
● PP food-grade boxes
● Chain & sprocket conveying system
● Touch screen control panel (PLC)
● Multi-level grading discharge ports
● Automatic box recycling system
2)How Does a Box-Type Weight Sorter Work?
1. Feeding
Products are manually or automatically placed into each sorting box.
2. Weighing
Each box passes the high-precision weighing sensor. The system records real-time product weight.
3. Grading
The controller compares measured weight with preset grade standards.
4. Discharging
When the box reaches the correct grade channel, it automatically opens and releases the product.
5. Recycling
Empty boxes return to the feeding position for continuous cycling.
