The peanut oil pressing process is slightly different according to the customer's investment budget and production scale. Next, let's take a standard peanut oil production line as an example to introduce the peanut oil pressing process.
Peanut pretreatment and pressing is an important step in processing peanuts and obtaining peanut oil. In order to make it meet the requirements of peanut oil production process. This process is very important and requires the following machines: shelling machine, cleaning machine, crushing machine, flaking machine, roasting machine, and pressing machine.
Main machines of peanut oil pretreatment & pressing:
Shelling: Most oil seeds need to be shelled before oil extraction. Shelling can not only increase the production capacity of peanut oil production machine and improve its efficiency, but also reduce the wear of peanut oil pressing machine. Shelling machine are commonly used in peanut oil pretreatment process.
Cleaning: Peanut oil pretreatment process we need cleaning machines, such as magnetic selectors, de-stonner and magnetic selector. These cleaning machines can help remove some impurities such as leaves, stones, sand, dirt, spoiled seeds and metal contaminants. The cleaning part avoids damage to other peanut oil production machines.
Crushing: Crushing is generally used for oil seeds with larger particles. This process requires the crusher to squeeze, bend, impact and shear to break the material into small particles.
Flaking: The purpose of flaking is to increase the contact area between the peanuts and the roaster and destroy the internal structure of the peanut cells, so as to facilitate the peanut oil pressing machine to press the peanuts.
Small scale peanut oil production line
Cooking: The peanut roasting machine can adjust the temperature and moisture of the peanuts. The peanut roasting process can make it reach the best situation. After that, we can send the prepared peanuts to the peanut oil press machine to squeeze out peanut oil.
Pressing: In the process of peanut pretreatment and pressing, the oil residue in the peanut cake after pressing is about 7％. The peanut cake can be extracted by solvent to get more oil. The biggest feature of our Henan Glory Company's peanut oil pressing machine is low energy consumption and less occupied area, so it is the first choice for peanut pressing.
filtering: The last is filtering. In general, for peanut oil production line, we will recommend to choose the plate filter, the machine cost is low and the filtration effect is good. Its working principle is to filter out the impurities in the crude peanut oil and take away part of the water through the action of squeezing.
