Smooth-Running Low-Specific Circulating Air Separation Gravity Impurity Separator Destoner Flow Stone Remover Machine for Paddy Pre-Cleaning

The circulating air destoner effectively removes two categories of impurities: Low-specific-gravity impurities: husks, dust, paper scraps, hair, and lightweight contaminants. High-density impurities: small stones, sand, soil clods, and metal pieces. The finished product and stone impurities are discharged through two separate channels for clean separation.

High-efficiency gravity wind separation, stone removal rate over 99%, effectively separate heavy stones, mud blocks from grains and spices, improve finished product purity.

Yes, equipped with frequency converter, air volume and feeding capacity can be adjusted steplessly according to different raw material impurities content.

The machine is highly compact and comes with an integrated discharging conveyor. The finished good products and the stone/clod impurities are automatically transported out via two completely separate channels. This automated dual-channel output ensures continuous, high-efficiency operation without any manual sorting labor

It is highly flexible. It works excellently as a standalone unit for independent spice or herb cleaning. Meanwhile, it is fully compatible to be used in combination with our circulating winnowing machines or Z/C-type elevators to form an all-in-one integrated automatic processing line.
