The Roller Sorting Machine is a highly efficient automated sorting machine based on dynamic gap adjustment technology, designed for food processing and agricultural products handling. The core principle is to achieve accurate grading of materials according to size through two stainless steel roller bar conveyor belts rotating in the same direction at a uniform speed and gradually enlarging the roller bar spacing during the conveying process. The main body of the equipment is made of SUS304 stainless steel, which meets the food-grade hygiene standard, and is suitable for spherical or spherical-like materials such as apples, potatoes, carrots, mandarin oranges, mangoes, garlic, etc., as well as aquatic products (e.g., lobsters, fishes, shrimps, shellfish) to be sorted on a large scale.
Structural components and technical details:
Transmission system
Motor drive: Equipped with 0.75kW (FJ3600 type) or 1.1kW (FJ4600 type) three-phase asynchronous motor, voltage 380V, supporting infinitely variable speed regulation.
Chain transmission: adopting high strength transmission chain and sprocket to ensure synchronous operation of rolling bar and reduce sliding friction.
Roller bar design: the upper layer is the fixed roller bar, the lower layer is the movable roller bar, the movable roller bar gradually increases the distance between it and the fixed roller bar through the step-down mechanism, the distance adjustment range is from 9.7mm to 50mm, and it supports 3-8 levels of grading.
Grading unit
Multi-stage screening device: each stage of the roller bar spacing can be adjusted independently, the last stage is equipped with a top bar cleaning device to prevent the material from being stuck.
Discharging system: the graded materials are output through special hopper and conveyor belt, supporting multi-way sorting.
Safety and Maintenance
Protective Design: The surface of the roller bar is covered with food-grade flexible silicone or plastic to reduce the rate of material skin damage (<2%).
Cleaning Convenience: The whole machine supports quick disassembly, smooth contact parts without dead angle, equipped with high-pressure water gun interface.
Mobility: the bottom with universal wheels and fixed feet, adapt to the flexible layout of the workshop.
