Introduction To Rapeseed Oil Extraction Technology
Rapeseed oil is one of the oldest known vegetable oils, but historically was used in limited quantities due to high levels of erucic acid, which is damaging to cardiac muscle of animals, and glucosinolates, which made it less nutritious in animal feed. Rapeseed oil can contain up to 54% erucic acid. Rapeseed contains upto 35kg of oil from 100kg rapeseeds.
The rapeseed oil extraction plant can be divided into four main parts which are as follows
- Rapeseed Oil Expeller
- Rapeseed Oil Filter Press
- Steam Boiler
Rapeseed Oil Expeller
Rapeseeds are fed in the feeding hopper of long cooking kettle for cooking purpose. Cooking of rapeseeds is necessary for highest recovery and long life of rapeseed oil. Long cooking kettle is provided for the proper cooking of the rapeseeds. The cooking kettle has given a special shape for maximum heating surface and the better cooking.
The cooked rapeseeds will be automatically dropped in the expeller and the expeller extracts (crushes) the cooked rapeseeds with the highest extraction pressure and produces the oil and by product (cake). The extraction chamber of expeller is specially designed for the highest recovery of oils as well the complete design of expeller is heavy duty for the best performance.
The filter pump is attached with the expeller and it supplies the extracted oil from the oil tank of expeller to filter press with high pressure.
Rapeseed Oil Filter Press
The filter press filters the extracted rapeseed oil by using the micro filter cloths to make it edible. Filtered rapeseed oil will be a very cleaned, transparent, fresh, pure and natural in taste without any chemicals and hence there is a big demand of the same rapeseed oil at everywhere. The filtration chamber of the filter press is specially designed with membranes plates for the best performance.
