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.

Edible Oil Refining Process – Degumming

Hydration Degumming: Hydration degumming mean adding into some hot water and controlling the corresponding conditions to make the hydrosol agglomerated, 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 – Neutralizing

Since there are many kinds of oilseeds and the oilseeds quality is different from each other,

we combine the merits of many technologies and develop the versatile neutralization washing technology. The technology can be used to process oil of various kinds, quality and requirements.

Add into alkali, water and acid to remove FFA, crude phospholipids and moisture.

As a result, (degummed and neutralized) oil and by-products such as soap foot, crude phospholipids and water are obtained.

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.

Edible Oil Refining Process – Deodorizing

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.

Edible Oil Refining Process – Dewaxing

Dewaxing can improve oil quality, so it plays in important role to the finished edible / vegetable oil quality.

At the same time, dewaxing can improve oil transparency and brightness.

It is necessary to dewax for some oilseeds such maize oil, rice bran oil, sunflower oil and cotton seed oil.

At present, winterizing method is very popular to dewaxing.

The crystallizing rate, crystallization temperature, maturing time vary with oil features
