Rapeseed Oil Production Line
The rapeseed oil making production generally adopts pressing → refining or pre-press→solvent extraction→ refining. To make rapeseed oil into edible rapeseed oil that meets the national standard, it is necessary to remove a small amount of impurities and unsuitable components such as free fatty acids. , Aldehydes, ketones, hydrocarbons, alcohols, sulfur compounds, etc.
Rapeseed oil production process have one-time press method and pre-pressed--solvent extraction method.
The fragrant rapeseed oil process:
Raw rapeseed oil→ impurity removal→ stone removal→ magnetic separation→ fried seeds→ press→ filter→ crude oil.
Rapeseed oil cake→ animal feed/solvent extraction
The refining rapeseed oil process:
Machine-squeezed rapeseed oil contains 300-350 mg/kg of phosphorus, and reaches the fourth-grade rapeseed oil standard through dephospholipid and water impurities. Generally adopt low-temperature anhydrous degumming process and low-temperature hydration degumming process for refining.
1. Low temperature anhydrous degumming process
Crude oil→ clarification tank→ cooling tank→ plate and frame filter→ product
2. Low temperature hydration degumming process
Crude oil→ filtration→ cooling→ hydration tank→ settling tank→ products
Choose fresh, high-quality rapeseed. The moisture content of raw materials should not exceed 10%, and the impurities should not exceed 3%.
Pretreatment process includes impurity removal, stone removal and magnetic separation. Through vibrating cleaning screen, stone remover, magnetic selector to remove various impurities in the oil, ensure the high quality crude oil and the value of the cake.
Frying seeds is a key process in the production of strong coriander seed oil. The moisture and temperature of the rapeseed after being fried, and the pressing temperature of clinker should be strictly controlled to ensure high oil yield and the quality of fragrant rapeseed oil.
Adopt high-pressure screw oil press for pressing, the cake thickness is generally controlled at about 1.5mm, and the residual oil can reach 7-8%.
