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, Hongri 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.
