What is the Refinery ?

It is a process of wiping off the impurities from the crude oil . Refining of vegetable oils is essential to ensure removal of gums, waxes, phosphatides and free fatty acid (F. F.A.) from the oil; to impart uniform colour by removal of colouring pigments and to get rid of unpleasant smell from the oil by removal of odiferous matter.

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.

3.Details: High-vacuum steam ejection deodorization and fully auto-control system are applied to oil dedorization process, which are designed by Zhengzhou FIRST. Besides, our company has developed the brand-new combined multi-plate deodorization process. It provides perfect technique and service to satisfy the customs’refining requirement and to create first-class refining process.

Zhengzhou FIRST Grain and oil machinery co., LTD can provide design, manufacture, installation, calibration and after service of oil dedorization process. Deodorization process: This process is to remove the odor substances such as the odor in the leaching solvent process, soap odor in the alkali refining process and clay odor during the decolorization process. as well as remove part pigment residue.
