Introduction To Cottonseed Oil Extraction Technology
Cotton seed is a textile plant that is mainly cultivated for its lint. However, the seed contains 15 – 25% oil and produces a protein-rich oilcake, which is used as a protein supplement for cattle.
The cottonseed oil extraction plant can be divided into three main parts which are as follows
- Cottonseed Oil Expeller
- Cottonseed Oil Filter Press
- Steam Boiler
Cottonseed Oil Expeller
Cottonseeds are fed in the feeding hopper of long cooking kettle for cooking purpose. Cooking of cottonseeds is necessary for highest recovery and long life of cottonseed oil. Long cooking kettle is provided for the proper cooking of the cottonseeds. The cooking kettle has given a special shape for maximum heating surface and the better cooking.
The cooked cottonseeds will be automatically dropped in the expeller and the expeller extracts (crushes) the cooked cottonseeds 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.
Cottonseed Oil Filter Press
The filter press filters the extracted cottonseed oil by using the micro filter cloths to make it edible. Filtered cottonseed 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 cottonseed oil at everywhere. The filtration chamber of the filter press is specially designed with membranes plates for the best performance.
