Soybean oil refining is to add edible phosphoric acid, sodium hydroxide, decolourisation active white clay and other process auxiliaries, after a series of processes to remove impurities and components affecting the colour, stability and flavour, to improve the quality, flavour and storage stability.
Why is automatic soybean oil processing plant necessary?
Automatic soybean oil processing plant is necessary because of the low efficiency of the oil extracted by hand operated machines.
How is soybean oil extracted?
Two common soybean oil production processes are solvent extraction (chemical) and mechanical extraction using a screw press. The most conventional method is to extract oil by mechanical oil processing machines. The oil obtained from screw press, known as crude oil, usually undergoes a filtration process before being consumed as food.
