What is the basic principle of peanut oil solvent extraction?

The solvent extraction of peanut oil is a process of extracting peanut oil with n-hexane as extraction solvent. The process consists of four systems: solvent extraction system, wet meal desolventizing system, mixed oil evaporation system, and solvent condensation recovery system. Here I will introduce how these systems works.

Peanut oil solvent extraction system

The mixed oil and wet meal were obtained by desolventizing peanut oil in peanut meal with n-hexane organic solvent in the leaching system.

Wet meal desolventizing system

This system use desolventizing toasting drying and cooling tower (D.T.D.C) to desolventizing, toasting, dry and cool the mixed oil in the evaporated wet meal, and the dry meal can be used as animal feed.

Mixed oil evaporation system

The system has three main equipment: the first long tube evaporator, the second long tube evaporator and the stripper. After being treated, the solvent in the mixed oil is evaporated and enters the solvent condensation recovery system.The peanut oil will be fed into the peanut oil refining plant.

Solvent condensation recovery system

The solvent evaporated by the mixed oil evaporation system passes through the condenser, and then is stored for recycling in the next production.

At this point we have the peanut extract oil and finish the whole treatment.

This is the general process of peanut oil solvent extraction. If you have more questions, please contact us. Henan Glory Oils & Fats Engineering Co., Ltd will provide you with professional service.
