rapeseeds oil refining

Rapeseeds oil refining process is prepress crude oil, pump, add phosphoric acid, centrifugal mix, oil refining pot, heater, continuous vacuum dehydrating.

As physical refining deacidification is in deodorization process, except high temperature and high vacuum the production condition, deodorization tower structure design reasonable is the key of deacidification effect, in the deodorization process, the deodorization tower is disk structure, total seven layers, the six layers are work layers, inside is heat transfer oil heating coil set, to keep deacidification deodorization need temperature, the tower not only has deacidification deodorization function, after decolorizing ability also obvious, compare with chemical refining, physical distillate fatty acid is relatively large amount, so must enhance fatty acid capture function, good for protect environment, and obtain certain economic benefit.

Choose semicontinuous process, degumming, dephosphorization section mainly focus on decoloration, deodorization, thermal of fumace, greatly save the investment.
