Foodline Weight Sorting Machine for Sale
This sorting machine for weight is an automated system that weighs each product individually and sorts it into different weight grades based on preset weight ranges. It is a flip type weight sorting machine that uses a flip-over tray to guide the product to the correct output channel after weighing.
Each product passes through the weighing area in sequence. The machine uses high-precision sensors to measure the weight in real time. The control system compares the measured weight with the preset weight ranges. When the product reaches the sorting position, the tray flips, sending the product to the correct grade.
Our weight sorter machine typically supports 4 to 12 weight grades, and Foodline can customize more grades if needed. Customers can easily change grading parameters via a touchscreen without complex training.

Main Features of Weighing and Sorting Machine
1. Advanced Control System
The weight sorting machine uses a digital control system for stable daily operation. It supports accurate dynamic weighing with automatic zero tracking. All settings are adjusted through a touch screen with an English menu. Operators can change sorting speed based on capacity.
2. Stable and Durable Frame
The automatic weighing sorter follows an ergonomic layout and uses SUS304 stainless steel with a welded structure. This gives the machine good rigidity and long-term stability. The stainless steel material resists corrosion and fits wet or demanding working conditions. A solid frame helps reduce vibration during operation and supports reliable weighing results.
3. Food-Grade Resin Trays
The sorting trays are crafted from food-grade resin material that complies with food contact standards. This material can withstand repeated impact and friction during operation and performs well in continuous usage. The smooth surface lessens product friction and facilitates regular cleaning.
4. User-Friendly Touch Screen Interface
Weight grading ranges are set directly on the screen without complex steps. Parameter adjustment is quick and clear. Sorting levels can be adjusted based on customer requirements, which allows the same machine to handle different products.
5. High-Accuracy Sensors
The weight sorting machine uses imported weighing sensors with stable performance. The system tracks the zero point automatically during operation, which helps limit measurement deviation. This setup supports accurate weighing when the machine runs at higher speeds.


Benefits of Using High-Quality Weight Sorting Grading Machine
Our product weight sorter has clear advantages
The flip sorting structure guides products in a smooth and controlled way. Product impact stays low during movement through the sorting area.
