The purpose of preparation is to make soybean to be suitable for effective solvent extraction. Main processes include: Cleaning, Conditioning, Cracking and Dehulling, Flaking, and so on.
Soybean oil pretreatment machine
Description of Process:
1. Cleaning
From daily warehouse or silo, soybean is conveyed into the preparation line. The purpose of cleaning is to remove impurities, for improving quality of final product.
2. Conditioning
Moisture and temperature of soybean are adjusted by Vertical Conditioner, so that soybean can be easy to be shaped. The process aims to achieve high dehulling rate and low protein denaturation.
3. Cracking and Dehulling
The purpose of cracking and dehulling is to improve protein content and reduce fiber content of soybean meal. In addition, it can enhance extracting efficiency and reduce residual oil contained in the hulls.
4. Flaking
The purpose of flaking section is to destroy the cells of soybean and increase the surface area, in order to improve efficiency of expanding and solvent extraction. Flaking mill is designed to flake the broken soybean into thins flakes (thickness from 0.3 to 0.4mm). Flakes thickness can be adjusted by adjustment of pressure between rolls. Soybean flakes will be conveyed to soybean oil solvent extraction plant.
