What is the basic principle and method of making peanut oil?

peanut oil processing

Peanut is the main oilseed in the oil extraction market. Its oil content is 40%-50%. That is to say, 100 kilograms of peanuts can squeeze 40-50 kilograms of peanut oil. Therefore, many people will choose peanut oil press. So, first of all, we must understand the peanut oil processing and what machines are needed?

Complete peanut oil production line: peanut shelling, frying seeds, pressing, filtering, peanut oil refined.

Flower production line machines: peanut sheller machine, electric cooker, peanut oil press, peanut oil filter, peanut oil refinery.

Secondly, we also need to know what is the principle of squeezing peanut oil? How to extract peanut oil? Next, Benteng Machinery will give you a detailed introduction of peanut oil processing.

 The basic principle of making peanut oil.

The principle behind the peanut oil press is that when the motor decelerates before being transferred onto the shaft. the shaft’s screw turns and it is constantly being pushed ahead. The oil’s density increases, and the pressure increases gradually. When pressing, because the machine is heated every day The temperature of the main machine body is increased due to the temperature control system that is automatic which reduces the work intensity, wear and tear of the press, energy savings along with environmental safeguards.

Peanut oil processing

1.  Peanut sheller

Peanuts must be shelled before being pressed. Because peanut shells will not only affect the oil yield of peanuts, but also cause certain damage to the oil press. for a long time. There will be problems in oil extraction, and the service life will be shortened. This is very unfavorable for those who run oil factories. So, remember to use a peanut shelling machine to incrase the oil output rate of peanut.

2. Frying seeds

The quality of the oil frying process is an important factor that affects the yield of oil. Through the frying of the seeds in the oil, the temperature and water of the oil seeds are adjusted. Before the oil seeds are pressed the chamber must be able to ensure that the right temperature appropriate for oil pressing is achieved. In order to ensure that there is a normal output from the oil, the pressure in the pressing chamber is managed by adjusting the cake’s thickness. This can be done and allowing extra time for an adequate output from the cake and the oil.

3. Pressing peanut oil

After frying, the peanuts can enter the oil press for pressing. When pressing, pay attention not to feed too fast, and feed slowly. If the feed is too fast, the pusher wire will be squeezed out. When pressing, the temperature of the controller should be adjusted in time, and the temperature should not be too high.

4. Filtering peanut oil

How to filter peanut oilThe oil flows out from the oil line and the cake gets pulled out from between the cake outlet and outlet for the cake. The spilled oil is pumped into the barrel of oil filtering through the oil pan the vacuum pump pulls out the air within the barrel. A negative pressure is created in the barrel. The oil is then pumped into the barrel using the filter fabric and the remaining oil is then filtered off on the cloth. In this stage, pure oil is extracted. After filtering, the peanut oil color is clean and bright.

5. Refining peanut oil

Refining peanut oil requires a refiner. If you have high requirements on the quality of the oil, you can choose to use refining equipment. The soybean refining process is very complicated, see this article for details: what is refined peanut oil?
