Introduction To Soybean Oil Extraction Technology

Soya beans contain between 15 – 22% oil and importantly 40% high quality protein. Soya also contains several anti-nutritional components in particular indigestible sugars that cause flatulence, and trypsin inhibitors that interfere with the absorption of certain amino acids in the protein.

The soybean oil extraction plant can be divided into four main parts which are as follows

  • Soybean Cracker
  • Soybean Oil Expeller
  • Soybean Oil Filter Press
  • Steam Boiler

Soybean Cracker

The soybean seeds are allowed to undergo the soybean seed cleaning process to make the best use of them. A soybean seed cracker is an important machine which finds a place in the soybean oil extraction plant. We all know that all the soybean seeds differ in size. Soybean seed cracker are used to reduce the size of the soybean seeds and make them suitable for oil extraction.

There is an inlet hopper at the top of the machine for feeding the soybean seeds into the machine. The internal structure of the machine is enclosed with the casing. When the soybean seeds fall into the chamber, the rotating blades will break the soybean seed into smaller pieces. A special outlet is provided at the bottom of the soybean seed cracker for the soybean seeds to come out.

Soybean Oil Expeller

Cracked soybean seeds are fed in the feeding hopper of long cooking kettle for cooking purpose. Cooking of soybean seeds is necessary for highest recovery and long life of soybean oil. Long cooking kettle is provided for the proper cooking of the soybean seeds. The cooking kettle has given a special shape for maximum heating surface and the better cooking.

The cooked soybean seeds will be automatically dropped in the expeller and the expeller extracts (crushes) the cooked soybean seeds 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.

Soybean Oil Filter Press

The filter press filters the extracted soybean oil by using the micro filter cloths to make it edible. Filtered soybean 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 soybean oil at everywhere. The filtration chamber of the filter press is specially designed with membranes plates for the best performance.
