The main process include crude oil extraction, wet meal desolventizing, mixed oil evaporation and stripping, and tail gas recovery.

During the technology of corn germ oil extraction, the pre-pressed cakeis transported to extractor by a conveying device, and after being mixed with solvent can get the concentrated mixed meal and wet meal.So the extraction machine is very important, Lingfine company have the following extractor:

1.Continuous type include Rotocel Extractor,Loop Type Extractor, Ballyuan Extractor.

2.Intermittent type include tank group type extractor.

In addition ， Desolventizer-toaster， Solvent Tank， Evaporator， Stripping Column,and tail gas recovery machine also are important machines in corn germ oil solvent extraction plant.

Main technical parameters and index of Corn germ cake

1.Cake thickness: 10-12mm
2.Moisture: 4-6%
3.Oil residue: about 14%
