Peanut oil is an important edible oil that is widely used around the world and is very popular among consumers in the market. There are many types of peanut oil on the market. Common ones include first-grade pressed peanut oil, strong-flavor peanut oil, extracted peanut oil, peanut blended oil, etc. The difference between these oils mainly lies in the raw materials and processes used in production. Let’s briefly introduce the processes used in these types of peanut oil:

 First-grade pressed peanut oil：

First-level pressed peanut oil is the peanut crude oil extracted from the oil press after the raw peanuts have been cleaned, stoned, shelled, crushed, steamed and fried and other pre-treatment processes, and then degummed, deacidified, dehydrated, decolorized and deodorized by the oil refining equipment. The finished peanut oil is obtained by refining and removing impurities through processes such as , dewaxing and other processes to remove a series of impurities such as phospholipids, free fatty acids, moisture, pigments, waxes and harmful substances in peanut oil.

 Strong fragrance peanut oil:

The processing technology of strong-flavor peanut oil is roughly the same as that of first-grade pressed peanut oil, but strong-flavor peanut oil has very high requirements for the quality of raw peanuts, and the relevant indicators need to be higher than the national standards for first-grade peanut oil. The oil to produce strong-flavor peanut oil requires mature kernels with full kernels, which have not gone through the aging period, and must not have moldy kernels, damaged kernels, immature kernels, etc. During the production process, after the peanuts are cleaned, stoned and dusted, they are quickly fried at high temperature in a drum wok to create aroma, and then pressed in one step to produce strong-flavored peanut oil, which ensures its high quality and unique aroma. Different from the first-stage pressed peanut oil refining process, strong-flavor peanut oil uses anhydrous dephosphorization and low-temperature crystallization processes to remove phospholipids and waxes in the crude oil to obtain the finished strong-flavor peanut oil.

 Extracted peanut oil：

Leaching peanut oil is a process in which the pre-pressed peanut oil cake is crushed and fully contacted with the solvent in the leaching equipment to extract the remaining oil in the cake. Peanut oil has a high oil content. Generally, the pre-pressed-leaching process is used to extract the oil, and the oil is pre-pressed first. About 80% of the peanut oil is extracted, and then the remaining oil cake is broken to extract the remaining oil. The leaching equipment can control the residual oil in the cake within 1%, greatly improving the oil yield of the finished product. After the leached oil is removed from impurities by the oil refining equipment, the finished product leached peanut oil that meets the national standard can be obtained.

 Peanut blended oil：

Peanut blended oil is made from refined peanut oil and other types of edible oil through scientific blending and professional processing. It can make up for the unreasonable nutritional function structure of a single type of edible oil. Blended oil is made from refined edible oil.

The above are the production processes of four kinds of peanut oil. The required output is different, the processes and equipment used are different, and the grade and quality of the finished edible oil obtained are also different.
