Refining

Refining is an essential process for a complete oil pressing line because there are still some impurities such as phospholipids, FFA, pigment, odor,etc. in the crude oil. As a prominent oil press machines manufacturer who is devoted to processing pure edible oil for worldwide customers, we can provide professional technical support and manufacture first rate machines for your oil refining.

Oil Refining Equipment

1. Decoloring tank: bleach pigments from oil.

2. Deodorizing tank: remove the un-favored smell from decolorized oil.

3. Oil furnace: provide enough heat for the refining sections which need high temperature of 280°C. 4. Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755mmHg or more.

5. Air compressor: dry the bleached clay after bleaching.

6. Filter press: filter the clay into the bleached oil.

7. Steam generator: generate steam distillation.

Edible Oil RefineryProcess – Degumming

Hydration Degumming: Hydration degumming mean adding into some hot water and controlling the corresponding conditions to make the hydrosol agLDomerated, deposited and then separate them. The separated gum(after being dried) can be made into lecithin or added into cakes or meals in the extraction workshop. Hydration degumming process can improve oil edibility, storage and do good to downstream neutralization section. Special Degumming: The technology is specially developed to meet the demands of physical refining for edible / vegetable oil refining. Add small quantity to acid or dilute base to the vegetable oil, strictly control the corresponding conditions to separate out the hydrated gum and un-hydrated gum. Gum level in oil should be controlled to suitable for downstream processing.

Edible Oil Refining Process – Bleaching

High activity clay is added into oil. Mix and heat mixture of oil and clay to make the small particle of pigment absorbed on the crystal of clay. At last filter the oil. Perfect mechanism, liable performance, well configured equipment.Bleaching Tower and Filters ensures excellent bleaching and separation effect.

Combined deodorizing is the latest technology, which improves oil flexibility significantly. Detailed deodorizing process in the entire oil refining plant is: Most heat of bleached oil is recovered by Heat Exchangers. The bleached oil is heated to the process temperature by mineral oil or high pressure steam and then the oil enters into the Combined Deodorizer. The Deodorizer is a combined type: The upper is packing structure, which is used to remove odor components like FFA; the lower is a plate type used for heat bleaching and making product quality more consistent.

Oil coming from the Deodorizer is cooled and stored after series of heat exchanger. Volatile like FFA is collected and stored as by-products.
