What's Subcritical Biological Solvent Extraction Plant Equipment
Subcritical biological solvent extraction plant equipment is a kind of process that is slightly different from traditional oil leaching projects and traditional oil solvent extraction plant. It uses a special #4 solvent to soak up the oil. Subcritical biological solvent extraction ensures the invariance of oils through low temperature extraction process. It is mainly used for the extraction of precious oils, such as wheat germ oil, evening primrose oil, tea seeds oil, camelina oil, pomegranate seed oil, cocoa butter, flaxseed oil, rice bran oil, grape seed oil and more.

Oil Solvent Extraction Plant Equipment
Subcritical biological solvent extraction technology is also known as #4 solvent extraction. The main solvents of #4 solvent are liquefied propane and butane. Compared to #6 solvent extraction technology that is widely applied in oil solvent extraction plant, subcritical biological solvent extraction equipment has many remarkable economic and social benefits. First, the most prominent advantage of subcritical biological solvent extraction plant equipment is low temperature leaching and low temperature desolventing that ensures no damages on the active ingredients and plant protein of oils, which creates great condition for the extraction of valuable or precious oils and development and utilization of plant proteins. Secondly, the steam consumption of subcritical biological solvent extraction machine is less. The energy consumption during the extraction process can be reduced by more than 80%, thus lowering production cost and pollution emission. At the same time, compared with supercritical fluid extraction (SFE) method, subcritical biological solvent extraction plant equipment requires lower investment cost and can form large scale production.

Working Principle of Solvent Extraction Plant
Solvent Extraction Plant Process
#4 solvent is purified from liquefied petroleum gas (LPG), its main composition is propane, butane, and its boiling point below 0 ℃. The leaching process is carried out at a certain pressure (0.1 ~ 0.7 Mpa its state is liquid) and room temperature to extract oils. Therefore, subcritical biological solvent extraction plant equipment can achieve leaching oils at normal temperature. And the solvent within the oil meal and crude oils can be recylced through desolventizing at normal temperature and vacuum condition and liquefaction.
Advantages of Subcritical Oil Solvent Extraction Plant
The #4 solvent, butane and liquefied pronane, is low in boiling point, pure in composition, low in residue of leaching products. The extraction is at low temperature condition, #4 solvent has good selectivity, so the impurities are less extracted, which makes high quality crude oils.
