What are the core steps in making peanut oil?
Want to make peanut oil? It needs more than just squeezing peanuts. Understanding the steps is key.
Making peanut oil involves key steps. These include preparing the peanuts, pressing the oil out, and then cleaning the oil. We do this to get high-quality edible oil.

Let us look closer at each main part of the process.
Why do peanuts need preparing before pressing?
Raw peanuts are not ready for pressing. They contain shells and dirt. Proper preparation is necessary.
Peanuts need cleaning, shelling, and cooking or roasting before pressing. This removes waste and gets the oil ready for better extraction.


Cleaning is the first step. Machines remove unwanted things like dust and small stones. This keeps the oil pure. Shelling takes off the hard outer layer. The shells are waste in oil making. Removing them helps the press work better. Crushing breaks the kernels into smaller pieces. This prepares them for heating. Heating the peanuts is also important. We use steam or dry heat. This makes the oil flow easier when pressed. It helps get more oil out. This heating step prepares the peanuts for the next machine. Proper pretreatment makes the whole process better. It leads to higher oil yield and cleaner oil. We offer machines for all these steps.
How does a machine get oil from peanuts?
Getting the oil out is the main goal. Presses use force to squeeze oil from the prepared peanuts.
Machines use pressure to squeeze oil from heated peanut kernels. Screw presses push material through a barrel. Oil comes out, and solid cake remains.

Prepared peanuts go into the press machine. We use screw presses often. A rotating screw pushes the material forward. The space gets smaller inside the barrel. This creates great pressure. The pressure forces the oil out of the peanut cells. The oil goes through small slots in the barrel. It is collected below the press. The dry solid part is left behind. This is called oil cake. It comes out at the end of the press. The oil at this point is crude oil. It still has impurities. The design of the screw and barrel is important. It affects how much oil we get. Our machines are built for high efficiency. They get maximum oil from the peanuts.
What happens to the oil after pressing?
Crude oil from the press is not yet ready for food. It contains things we need to remove. Refining makes it clean.
After pressing, crude peanut oil needs refining. This process removes unwanted materials like gums, acids, colors, and odors. It makes the oil pure and stable.

The crude oil needs cleaning up. This is called refining. The first step is degumming. We add water or acid to remove gums. These gums make the oil cloudy. Next is deacidification. We take out free fatty acids. These make the oil go bad faster. We can use chemicals or heat for this. Then we remove the color. We use special clay that absorbs color. This is called bleaching. Finally, we take out the smells. We heat the oil with steam in a vacuum. This removes things that make oil smell or taste bad. This makes the oil clear, clean, and ready to use. Some processes add a filtering step at the end. This removes any small solid bits left. Refining gives us edible oil that meets quality standards. We supply equipment for batch and continuous refining processes.
Making peanut oil involves preparing peanuts, pressing the oil, and refining it. Each step is important for quality. We provide machines for every part.
