Edible oil refining machine for purifying the crude cooking oil

Henan Doing Mechanical Equipment Co., Ltd is committed to the design and manufacture of palm fruit deep processing machine. Our company has research institution which develops new products and we have our own experimental base, and we are committed to bringing in new technology, renewing products, keeping leading in this field, such as palm oil extraction machine, palm kernel oil expeller, palm oil /palm kernel oil refinery & fractiontation plant and so on.

Technology Description of edible oil refining line:

1. Degumming is the first step in soybean oil refinery plant. In this step gums in crude oil are removed by hydration with the help of phosphoric acid.

2. In this step, free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.

3. During bleaching process, unwanted pigments are adsorbed physically and oil will become much clearer.

4. Deodorization machine is used to remove unacceptable odors by steam distillation during soybean oil refinery plant, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
