In fact, the steps of making peanut oil in factory is similar with that you make it at home, including preparing the peanut, removing the impurities in peanut, husking, extracting peanut oil and filtering. The difference is the machines you used. Usually, the peanut oil making machines used in factory are more expensive, but have better effect. If you want to make peanut oil by building a peanut oil processing factory, the following steps and machines are all you should know.

Peanut oil making machine and working process
First, to remove the impurities in peanuts by cleaning machines.
Next, to broken the peanuts to small pieces. The function of this machine is to increase the area of oil seed and make the pressing easier.
Then, to soften the peanut which helps to adjust the water content of the material and improve the oil yield rate.
Finally, to make the peanut into flakiness. The thickness of cake is about 0.5mm.
After this, you can send the prepared peanuts into peanut oil press machine to squeeze peanut oil out.
Step 3 – Press the peanuts to get peanut oil
During this process, you need peanut oil press machine also named screw penaut oil press machine. Peanut oil press machine squeezes out the peanut oil from peanuts. After peanut oil press machine, you can get crude peanut oil.

Peanut oil filter machine can remove the impurities in crude peanut oil
Step 5 – Filling the peanut oil
When the oil is completely clean after filtering, you can use peanut oil filling machine to pack the peanut oil into bottles or into barrel for sale.
