The pressing method is a common method for processing peanut oil in peanut oil processing plant. In peanut oil processing, pressing is a very traditional and common processing method. In this method, the oil in peanut seeds is squeezed out by mechanical pressing, and the finished peanut oil is obtained after a series of processing techniques.

First, the peanut oil processing plant will clean and screen the picked peanut seeds to remove impurities and weeds. Then the clean peanut seeds are sent to the press machine for pressing. The press squeezes out the oil in peanut seeds through high pressure, and also produces a certain amount of peanut residues. These peanut residues can be used as feed or other purposes, which realizes the full utilization of resources.
Next, the pressed crude oil is refined and purified by centrifugal separation and filtration to remove impurities and foreign bodies. The refined peanut oil has purer quality and better taste, and is more suitable for eating and processing into various foods.
Processing peanut oil by pressing method has the advantages of simple process, high utilization rate of raw materials and low cost. At the same time, this processing method does not need to add any chemicals, which is a green and environmentally friendly processing method. Therefore, in modern industrial production, pressing method is still one of the main methods of peanut oil processing.
Overall, pressing method is a traditional and effective peanut oil processing method. The oil in peanut seeds is completely squeezed out by mechanical force, and high-quality peanut oil is obtained after refining treatment. This processing method not only meets the requirements of food safety and environmental protection, but also can make full use of resources, which has high economic and social benefits. Therefore, in peanut oil processing industry, pressing method still has an important position and application prospect.
