High-Efficiency Multifunctional Peanut Oil Refining Machine with Deacidification, Dehydration, and Decolorization for Edible Oil Processing

The operation process of the Peanut Oil Refining Equipment mainly includes the following steps:

1. Raw material preparation:
Use the pressed peanut crude oil as the raw material for refining to ensure that the quality of the crude oil meets the refining requirements.

2. Degumming treatment:
Use the hydration degumming method or the acid degumming method to convert the colloid substances such as phospholipids in the crude oil into water-soluble substances.
Remove these water-soluble substances through centrifugal separation equipment to improve the purity of the oil.

3. Deacidification treatment:
Use the alkali refining deacidification method to add an appropriate amount of alkali solution to the crude oil.
The alkali solution reacts with the free fatty acids in the crude oil to generate soap stock and precipitate and separate.
Remove the soap stock through the filtering equipment to reduce the acid value of the oil.

4. Decolorization treatment:
Use adsorbents (such as white clay, activated carbon, etc.) to remove pigments and oxides in the oil.
After mixing the adsorbent with the oil, separate the adsorbent through the filtering equipment, so that the oil appears light yellow or colorless and transparent.

5. Deodorization treatment:
Use vacuum distillation to remove odor substances and residual solvents in the oil.
Under high temperature and high vacuum conditions, odorous substances and residual solvents are evaporated and collected and processed by condensation equipment.
The taste and quality of the deodorized oil are improved.
6. Cooling crystallization and filtration:
The refined oil is cooled and crystallized to remove residual impurities such as phospholipids and wax.
The impurities are further removed by filtering equipment to improve the purity of the oil.
7. Finished product storage and packaging:
The refined peanut oil is stored in a dedicated oil storage tank, maintaining suitable temperature and humidity conditions to prevent oil oxidation and deterioration.
According to market demand and customer requirements, the stored peanut oil is packaged by filling, sealing, labeling, etc. for sale and use.

During the entire operation process, it is necessary to pay close attention to the operating status and parameter changes of each equipment to ensure the stability and continuity of the refining process. At the same time, the equipment is regularly maintained and maintained to extend the service life of the equipment and maintain the performance of the equipment.
