The refining methods of edible oil are generally divided into physical refining and chemical refining.The principle and detailed operation process of edible oil physical refining and chemical refining will also be somewhat different.

There are too many impurities in the peanut oil pressed by the oil press, which affects the texture of the oil, so it needs to be refined by to remove the impurities in the peanut crude oil one by one.

The purpose of peanut oil refining is to remove impurities in crude peanut oil to obtain peanut oil that meets national standards. The general premise that whether peanut oil needs to be refined depends on the quality standard of peanut oil.

For the screw oil press, in order to be able to use the machine better and increase the oil yield, there are some matters needing attention to when operating the screw oil press.

Edible oil is pressed by an oil press. There are large oil presses, small oil presses, commercial oil presses, screw oil presses, household oil presses, etc.

The annual profit of establishing a corn germ oil plant needs to be calculated and analyzed from the entire production line process of corn germ oil processing.

How to choose a peanut oil press with high oil rate?Many friends who set up oil mills are eager to choose a good machine, which has a long life and a high oil output rate.

Type of suction hood：The suction hood is an important part of the ventilation and dust removal network. Its performance directly affects the economic benefits of the ventilation and dust removal network.

In grain enterprises, the most effective way to prevent dust from spreading indoors is to collect them directly in the place where dust is produced, and discharge it outdoors after being purified by a dust collector. This method of ventilation is call

The purpose of current edible oil bleaching is mainly to remove undesirable by-products in the oil, including those that are not conducive to food safety and sanitation.

Special degumming:It was developed by the Swedish (Alfa-laval) company, also known as the acid refining method.

Degumming is the process of removing colloidal substances in oil. It mainly removes phospholipids and trace metals combined with phospholipids, calcium, magnesium, iron, and other impurities. Its effect has an impact on deacidification, bleaching, deodori

Refined palm oil process:Palm fruit bunch → disinfection treatment → separation (palm fruit) → cooking → compression → screening → sedimentation tank → residual oil → centrifuge → drying vacuum machine → crude palm oil → chemical refi

The adsorption is mainly caused by the surface free energy of the superfine convex and concave surface of the adsorbent. After the oil and the adsorbent are in full contact, the pigment is adsorbed and finally reaches the adsorption equilibrium.

In palm oil fractionation, in order to speed up the crystallization speed, we usually add seed crystals to the raw materials to help crystallization. The added seed crystals have a higher melting point than the raw materials.

Crude palm oil is generally not degummed separately, although the phosphorus content is relatively low (generally less than 20PPM), However, it is best to add 0.05% phosphoric acid for degumming before bleaching, which helps to improve the stability a
