Which Peanut Oil Production Process Is Right For You?

Making peanut oil needs the right method. Picking one matters a lot. How do you know which one is best?

You can make peanut oil by pressing or by solvent extraction. Pressing uses force to squeeze oil out. Extraction uses chemicals to pull oil out. Your scale, budget, and goal help you choose.

Choosing the right method makes a big difference. It affects your oil’s quality and how much you make. Let’s look closer at each way.

What is Peanut Oil Pressing?

You have peanuts and want oil. How do you get it out just by squeezing? Is it simple?

Peanut oil pressing uses mechanical force to press oil from the nuts. The oil press presses the nuts tightly, The oil flows out. This is an older, simple method.

This method is very direct. You feed peanuts into a machine. The machine has a screw inside. The screw turns. It pushes the peanuts along a barrel. There is pressure and friction. This pressure breaks the cell walls in the peanuts. It forces the oil out. The oil comes out through small gaps in the barrel cage. The solid part, called cake, comes out the end. We make different types of presses. Some use one screw. Some use two screws. We have presses that add heat automatically. This helps get more oil. We use strong materials for the screws and cages. This makes them last long. The machines can run for a long time. This gives you lots of oil.

What is Peanut Oil Extraction?

Pressing squeezes oil. What about extraction? How does that work? Is it better?

Peanut oil extraction uses a solvent to dissolve the oil from the nuts. The solvent mixes with the crushed nuts. It pulls the oil out. Then you separate the solvent and oil.

This process is different from pressing. First, you often press the peanuts a little bit. This removes some oil. Then, you crush the remaining peanut cake. You put this crushed cake into a special machine. This machine is called an extractor. You add a chemical solvent, like hexane. The solvent flows through the cake. It grabs the oil from the solid parts. This creates a mix of solvent and oil. This mix is called miscella. You then heat the miscella. This boils the solvent. The solvent turns into gas. It goes away. The oil stays behind. You also remove the solvent from the solid cake. This makes sure no solvent is left in the oil or cake. This method can get almost all the oil out.

What are the Benefits of Pressing?

Why do people choose pressing? Does it give you good oil? Is it easy to do?

Pressing gives you pure oil. No chemicals are used in the process. The oil keeps its natural taste and smell. This oil is often called virgin or cold-pressed oil.

The biggest benefit is the oil quality. When you press peanuts, especially at lower temperatures, the oil is natural. It keeps nutrients and flavors. This is good for food oil. The process is also simpler than extraction. You need fewer machines. The system is smaller. This costs less to start. It is also easier to operate. You need less training for your workers. The machines need less complex maintenance. Pressing also makes a solid cake. This cake has protein. You can sell it as animal feed. Or you can use it for other things. For small to medium oil makers, pressing is often a good start. We have oil presses for both small and large users.

How Do You Choose Between Pressing and Extraction?

You know about both methods. How do you pick the right one for you? What should you think about?

Think about how much oil you want to make. Think about how much money you have to start. Think about the oil quality you need.

Your choice depends on your specific needs. If you are starting small, or want natural oil with good flavor, pressing is usually better. The machines are simpler. The cost is lower. You can sell the cake easily. If you want to make large amounts of oil and get the most yield possible, extraction is better. This is for big companies. They have the money for a large plant. They have skilled staff. They can refine the oil later. Sometimes, companies use both. They press first. Then they extract oil from the pressed cake. This is called pre-pressing and extraction. We can help you decide. We look at your goals. We look at your budget. We look at the peanuts you use. We design the right system for you.

What Equipment Do You Need for Each Method?

You chose a method. Now what machines do you need? Is it just one machine?

You need more than just the main machine. Both methods need steps before and after the main oil making.

For pressing, you need machines to prepare the peanuts. This might include cleaning them. You might need to heat them first. This helps get more oil. We call it stir frying, and we have an electric frying machine.After pressing, you need to filter the oil. This removes small pieces. We have oil filters. You might also want to bottle the oil. For extraction, you need more machines. You need equipment to crush the peanuts or cake. You need the extractor. You need machines to remove the solvent from the oil and the cake. You might need a dryer for the cake. You definitely need refining equipment for the oil. This makes it clean and safe. We offer all these machines. We can provide a complete set for any method. We design the whole line from start to finish. This makes setting up easy for you.

Choosing pressing or extraction depends on your goals. Think about scale, cost, and oil quality. Zhengzhou Fude Machinery can help you build the right plant.
