Oilseeds Cleaning Equipment Vibrating Screen Destoner for Edible Oil Mill

The Oilseeds Cleaning Equipment is the first and one of the most important units in any edible oil pretreatment line. Raw oilseeds normally carry between 1 percent and 6 percent impurities, and under poor harvest conditions this figure can reach 10 percent. Stones, dust, sand, metal fragments, plant stalks and husks not only lower the quality of the final crude oil but also accelerate wear on downstream crushers, flakers and screw presses. Removing these impurities early protects the whole line and keeps the process stable and predictable.

Our cleaning line combines four separation principles in a single compact configuration: size based screening, air based winnowing, magnetic extraction and density based destoning. Because each method targets a different class of impurity, the combined result is a clean and uniform feed that improves flake quality, raises oil recovery and reduces unplanned downtime. The equipment can be supplied as individual machines or as a complete integrated cleaning section with conveyors, bucket elevators and aspiration.

• Multi-stage separation: screening, winnowing, magnetic extraction and destoning combined in one compact line.
• Reciprocating flat screen: stable performance that removes oversized and undersized impurities from all kinds of oilseeds.
• Air-suction winnowing: removes dust, hulls, leaf debris and lint while reducing the dust load in the workshop.
• Permanent magnetic separation: cylinder and roller that capture ferrous metal fragments before shelling, crushing and flaking.
• Specific gravity destoner: suction type unit that separates stones and heavy particles by density and suspension speed.
• Modular construction: integrates easily with existing conveyors, bucket elevators and aspiration systems.

The cleaning equipment is applied at the head of edible oil plants handling soybean, rapeseed, cottonseed, sunflower seed, peanut, sesame, corn germ and rice bran. It suits both new turnkey projects and oil mills retrofitting an existing line, and it is normally paired with a magnetic separator ahead of any sheller, crusher or flaking machine.

Each unit is cleaned, anti-rust treated and wrapped in heavy duty export packaging before shipment. Electrical components are protected with moisture barrier film, and the screen decks and motors are braced to withstand sea transport. Every machine is functionally tested at our factory and delivered with an operation manual, spare screens and a twelve month warranty on core components.
