Overview

VERFOODSOLUTIONS weight sorting machine is an advanced, automatic online weighing and grading system designed to improve efficiency and accuracy in product sorting. Products are fed into the machine and transported to the weighing station, where high-precision load cells capture accurate weight data and transmit signals to the control system. The system’s touch screen compares real-time weights with preset ranges and, when products reach the designated outlet, waterproof solenoid valves trigger the tray tipping mechanism to discharge items into the appropriate grading channels.

This versatile weight sorting machine is widely applicable across various industries, including seafood, poultry by-products, fruits & vegetables, Chinese herbal medicine, frozen foods, and even industrial components. This automated process ensures efficient, consistent, and damage-free sorting, greatly enhancing production workflows in diverse sectors.

What is the working principle for the weight sorting machine?

The product is carried on food-grade trays to the weighing station for the weight sorting machine, where high-precision load cells measure the weight of each individual item. The weight data is sent in real-time to the PLC control system, which compares it against preset weight ranges configured via the touchscreen. When an item’s weight falls within a specific range, the system activates a waterproof solenoid valve to tip the tray and automatically discharge the product through the designated outlet. The machine operates continuously, accurately sorting products into different grades while recording the quantity and weight of each category for quality control and inventory management.

What products can this weight sorting machine sort?

This weight sorting machine is highly versatile and can sort many different types of products.

  • Seafood: oyster, abalone, sea cucumber, shrimp, pomfret, yellow croaker, scallop, crab.
  • Poultry products: chicken wings, chicken feet, chicken legs, duck necks, duck feet, whole chicken, whole duck, pigeon.
  • Fruits & vegetables: blueberry, potato, sweet potato and various fresh fruits and vegetables.
  • Other materials: frozen food, Chinese herbal medicine. Custom version is also available for industrial components such as motor rotors and auto spare parts.

How many sorting grades can this machine support? Can I adjust the grades freely?

The weight sorting machine supports 3 to 20 sorting grades. You can freely set the weight range for each grade on the touch screen according to your product requirements. Up to 99 product formulas can be saved, and you can quickly switch between different grading schemes.

Is the machine waterproof? Can I use it in wet food processing workshops?

The weight sorting machine adopts laser encapsulation with IP69 waterproof rating. The whole frame is made of SUS304 or SUS316 stainless steel, and the rejection adopts waterproof solenoid valve. It can withstand high-pressure washing, suitable for humid seafood, meat processing workshops.

What maintenance is required for the weight sorting machine?
