1. Soybean pretreatment flow chart:

material storage → lifting screw conveyor → magnetic separator → vibrating screen → specific gravity stoner → cracking → softening → flaking → extruder → drying → leacher 

2. Features:

1. Full continuous and mechanized operation, and with electrical interlocking control system. 

2. The equipment layout is in tower structure, and the material flow by relying on gravity to reduce reducing power consumption. 

3. In extrusion process, consider producing extrusion material in different proportions and raw germ extraction,and adjust it at any time according to product requirements.

4. When producing soybean germ meal, the roller softening pot can better meet the flaking technical requirements. 

5. Take into consideration the environmental requirements in modern industry.The workshop is also equipped with the dedusting system with high performance, so as to meet the requirements of production and environmental protection.

6. Select scraper conveyor as much as possible, which can effectively reduce raw material crushing, improve solvent permeation into the material layer, and increase the extraction efficiency. 

7. Our company adds soybean extrusion process after flaking process, to extrude the soybean germ, further destroy oil material cell, improve the productivity greatly and get the extruded meal that is well received by feed manufactures.
