The introduction of corn oil machine
The whole process of corn oil production line includes oil seeds pretreatment line, oil seeds press line, cake solvent extraction line, crude oil refining line(degumming process, deacidification process, decoloring process, deodorization process, winterization process and fractionation process.
1. Corn embryo pretreatment and press line
Cleaning--magnetic separator--vibrant sieve-- disc huller(for seeds with shell)--flaking--cooking--seeds pressing--Crude cooking/edible seeds oil(cake)
Raw materials for edible oil
2. Corn cake solvent extraction line
Cake solvent extraction process—desolventizing for cake—desolventizing for mixed oil—cooling and recycling system for solvent
Main part of corn cake extraction machine
3. Crude corn oil refining process
Crude oil degumming process—crude oil deacidification/neutralization process—crude oil decoloring process—oil deodorization process—oil winterization/fractionation process
Edible corn oil product after refining
