continuous oil refinery plant

A continuous refinery is recommended for periodic processing for plants with a higher capacity of over 30 tons per day and for oils with a higher content of FFA. This continuous refinery is slightly more expensive than a serial type refinery, but it provides top quality refined oil along with an automation system and low refining cost.
Our company is a leading developer, manufacturer and exporter of equipment for automatic refineries both in the continuous refinery and in the periodic refinery. It is very important that the crude oil obtained in the oil pressing workshop and in the solvent extraction workshop be refined in vegetable oil processing plants before it is used directly. Our continuous refinery ensures color uniformity and attractive oil quality, removing unpleasant odors and undesirable factors from the oil.

Our high-tech continuous oil refinery is widely used for all kinds of crude oil, such as cotton seeds, soybean, sunflower, palm oil, rice bran oil, etc.

Description of the process for a refinery:
The continuous processing line includes the following various processes:

1. Section dehumming or pre-processing
2. The neutralizing section
3. Whitening department
4. Deodorizing section
5. Section dewaxing

Degumming method:
This is the first step in a continuous refinery, also known as a pre-treatment process. In the process of degumming, the gums are deposited and separated by centrifugal separation. If the content of chewing gum in the oil is low, only conditioning of the chewing gum is required, and there is no need to switch to a separate process of degumming. Degumming can be carried out in the same vessel to neutralize.

Neutralizing method:
Each vegetable oil contains a certain amount of free fatty acids, which increase rancidity in the oil and are harmful to human consumption. In neutralization, FFA is removed by reaction with caustic soda-NaOH in a catalyst at a certain temperature and mixing. Thus, the FFA is separated in the form of a soap mass. Henan Doing Company offers neutralization units.

Whitening method:
Colored pigments in oil are removed during the bleaching process of a continuous refinery. Neutralized oil is treated with certain chemicals, such as activated earth, which removes color from vegetable oil. This process is also carried out at temperature. The bleached oil is then filtered so that added chemicals and particles are separated from the oil.

Deodorization method:

Deodorization is an important process in a continuous refinery. This process is used to remove odors from the oil. Each oil contains a certain typical natural color.
During previous processes, a certain undesirable odor is applied to the oils. The deodorization process removes this odorous material. This is carried out under conditions of high temperatures and vacuum systems. At the end of the process, we get the odorless vegetable oil.

Available capacity for a continuous refinery: from 50 dpi to 1200 dpi.
