Introduction
Have you ever wondered how oil is extracted from seeds and nuts? The process might seem complicated, but with the help of oil expeller machines, it's much easier than you think. Whether you’re a small business owner or just curious, understanding how these machines work can be very helpful.
In this guide, we'll explain how oil expeller machines work, what types are available, and why choosing the right one is important for your needs. We’ll also share a special offer from Creature Industry at the end, so keep reading!
What is an Oil Expeller Machine?
An oil expeller machine is a device used to extract oil from seeds and nuts. It works by squeezing the seeds under high pressure, which forces the oil to come out. The remaining solid part, known as oil cake, can be used as animal feed or fertilizer.
These machines are used in different industries like food production, cosmetics, and even biofuels. They can process many types of seeds, such as mustard, sunflower, groundnut, sesame, and more.
How Does an Oil Expeller Machine Work?
1. Preparing the Seeds
The first step is to prepare the seeds. This involves cleaning them to remove dirt and other impurities. Sometimes, the seeds are also roasted to make the oil extraction easier and more efficient.
2. Feeding the Machine
After preparation, the seeds are fed into the machine through a hopper, a funnel-shaped part that guides the seeds into the pressing chamber.
3. Crushing and Pressing
Inside the pressing chamber, the seeds are crushed under high pressure by a rotating screw. As the seeds are crushed, the oil is squeezed out. The machine’s bolt system, like in a 4 Bolt Oil Expeller Machine, applies the necessary pressure to extract the oil.
4. Collecting the Oil
As the seeds are pressed, the oil flows out through small openings in the machine. The oil is collected in a container, while the leftover solid part (oil cake) is pushed out separately.
5. Filtering the Oil
The oil is then filtered to remove any remaining impurities, leaving you with pure, clean oil that’s ready for use.
