Continuous oil refinery plant is recommended against the batch refining for higher capacity plants above 30 tons per day and for oils containing higher FFA content. This continuous oil refinery plant is bit expensive than batch type oil refinery plant but it provides superior quality refined oil along with automation system and low processing cost.
Our Company is a leading designer, manufacturer and exporter of state of the automatic oil refinery plants in both continuous type oil refinery plant and batch type oil refinery plant. It is very essential that the crude oil obtained from oil press workshop and solvent extraction workshop get refined in the vegetable oil refinery plants before it is utilized directly. Our continuous oil refinery plant gives color uniformity and appealing quality to the oil by removing unpleasant smell and undesirable factors from the oil.

Our high-tech continous oil refinery plant finds an extensive application for all types of crude oil like cotton seed, soyabean, sunflower, palm oil, rice bran oil etc.

Process Description for Continuous Oil Refinery Plant:
Continuous refinery line comprises of the following different processes:

1. Degumming or Pretreatment Section
2.Neutralizing Section
3. Bleaching Section
4. Deodorizing Section
5. Dewaxing section

Degumming Method:
This is the first step in continuous oil refinery plant and is also known as the Pretreatment Process. In the degumming process, the gums are precipitated and separated by the centrifugal separation technique. If the gum content in the oil is low, only gum-conditioning is required to be done and there is no need to go for separate degumming process. The degumming can be carried out in the same neutralization vessel.

Neutralizing Method:
Every cooking oil consists certain amounts of free-fatty acids FFA’s that increase the rancidity in oil and is harmful for human consumption. In neutralization, the FFA’s are removed by reacting them with caustic soda- NaOH in the neutralizer at a certain temperature and performing the stirring. In this way, FFA gets separated in the form of soap stock. Henan Doing Company offers neutralization units.

Bleaching Method:
The color pigments in the oil are removed in the bleaching process of continuous oil refinery plant. The neutralized oil is treated with certain chemicals like activated earth which removes the color from the cooking oil. This process is also carried out under temperature. The bleached oil is then filtered so that the added chemicals and particles are separated from the oil.

Deodorizing Method:

The deodorization is an important process in the continuous oil refinery plant. This process is used to remove the odor from the oil. Every oil contains certain typical natural color.
During the previous processes, certain unwanted odor is applied on the oils. The deodorization process removes this odiferous material. It is carried out under high temperature and vacuum systems. At the completion of the process, we get the deodorized-odorless cooking oil.

Available capacity for continuous oil refinery plant: 50TPD to 1200TPD.
