SOYBEAN OIL MANUFACTURING PROCESS
Soybean oil is one of the most widely used vegetable oils in the World, possibly because soybeans are the most widely cultivated and utilized plants. Soy oil takes the second place among the vegetable oils in the World market (while the first place belongs to the palm oil).
The production of soybean oil in 2017 reached 51.7 million tonns (based on the information for 2015/2016 marketing years)
There are 2 main technological processes for soybean oil extraction: 1) chemical extraction also known as solvent extraction is a process which involves extracting oil from oil-bearing crops by treating it with solvent (i.e. hexane) 2) mechanical pressing method or mechanical oil extraction which is completely natural, no additives or chemicals are used
BRONTO company offers the technology for non-chemical oil manufacturing, called as mechanical oil pressing.
Soybean oil manufacturing process consists of the following steps:
1) Soybeans PREPARATION:
- cleaning from impurities
- dehulling (if necessary)
- preheating to the temperature higher that 15°C
2) The process of SOYBEAN OIL MANUFACTURING
- extrusion
- pressing out the oil from the full fat soy
- cooling the oil cake down
3) SOYBEAN OIL MANUFACTURING process:
- removing the large solids using the settlement catchers
- oil settling, the solid particles and impurities are gravitationally settle down
- filtration, removing of small and fine particles
- oil refining, removing of phosphatides, some hydrophilic substances, fatty acids, purification from pigments, soaps and phosphate residues
