The first step in processing soybeans is to properly prepare the soybean for dehulling. This step typically involves using magnets to remove metal and screening to remove impurities that can interfere with the dehulling process.
Next, hulls are moved to both increase the protein content of the final meal product and also to improve the efficiency of the solvent extraction process. Finally, mechanical rollers are used to make thin flakes and rupture the cells containing the soybean oil.
Dehullling effects in soybean oil processing:
-- Improve protein contain inside soybean meal.
-- Increase production capacity of oil extraction -Dehulling can reduce solent contain and oil residue inside wet meal
-- Reduce energy loss during soybean oil processing
-- Improve soybean oil quality.
