Rapeseed oil production process is a complicated process.The first step in processing canola and rapeseed is to properly prepare the seed for oil removal.The first step in rapeseed oil production is to make oil by pressing or solvent extracting.The finally step in rapeseed oil production is to get the high-grade cooking oil from crude oil.

 Pressing Rapeseed Seed Oil technologe

(1) Cold Pressing Technology of Rapeseed 
Rapeseed→cleaning and decontamination→hulling and shell separation→cold pressing→cold-pressing oil→coarse filtration→clear filtration→quality cold pressed oil→rapeseed cake

(2) High temperature pressing technology of rapeseed
Rapeseed → cleaning → steamed stir fry → squeeze oil → sedimentation → filtration → rapeseed oil

(3) Refining Technology of Rapeseed Oil
Crude oil → degumming → deacidification → water washing → decolorization → deodorization → winter degreasing → finished camellia oil

(1) High oil yield , obvious economic benefit.
(2) Residual oil rate in the dry meal/cake is low.
(3) Improving the quality of the meal/cake and oil.
(4) Low processing cost , high labor productivity.
(5) High automatic and labor saving.
