Groundnut Oil Extractor | Peanut Oil Expeller

The automatic screw groundnut oil extractor is a compact machine designed for extracting edible oil from over twenty types of oilseeds, including peanut, soybean, sunflower, rapeseed, and more. It is primarily utilized in individual households and small oil pressing operations.

This machine can achieve an oil extraction efficiency of 20%- 50% of the seed weight, enhance the oil yield by 35%- 50% compared to traditional oil presses, and save 60% of energy for the same output.

Application range of oil press machine

This screw oil press is designed for processing a variety of vegetable oilseeds and nuts. Examples include mustard seed, sunflower seed, rapeseed, soybean, castor seed, shea nut, coconut or copra seed, neem seed, cottonseed, jatropha seed, corn germ, flaxseed, palm kernel, peanut, sesame seed, and more.

How to extract oil from groundnut seed?

The screw groundnut oil extractor is primarily made up of five key components: the automatic control box, the heating and pressing section, the adjusting mechanism, the rotating part, and the vacuum oil filtering system. Among these, the heating and pressing section is the most crucial for the entire machine’s operation.

The preparation of oilseeds prior to processing or extraction can vary somewhat, but it mainly hinges on the oil content and physical characteristics of the oilseed. However, almost all oilseeds go through the standard procedures of seed cleaning, drying, size reduction, flaking, cooking, and final conditioning.

1. Start by pouring the peanut kernels into the hopper. The machine’s screw mechanism will then push the material forward. As the space between the press chamber and the pressing screw narrows, the density of the oil material increases.
2. Consequently, the internal pressure also rises. This process generates heat due to friction between the oil material and the machine parts during pressing. The pressure breaks down the cellular structure of the peanuts, allowing the peanut oil to be extracted.
3. Next, the peanut oil moves through the vacuum filtering section, where any oil residue is separated and collected on top of the filter cloth. In the end, we obtain clean peanut oil. This outlines the complete process of extracting groundnut oil.

Screw peanuts oil extractor advantages

• Small footprint. It requires only 10-20 square meters of space.
• The well-designed pressing chamber increases internal pressure, significantly enhancing working efficiency.
• Wide range of applications. This machine can process over 20 different types of raw materials for oil extraction.
• High efficiency. Our peanut oil expeller can handle 500 kg of raw materials each hour, and it can be operated by just one person.
• Constructed from high-quality carbon steel, it is sturdy, durable, wear-resistant, and designed for continuous oil pressing.
• High oil output rate. A groundnut oil extractor can achieve an oil yield of approximately 50%, with the dry cake residue rate being 8% or less.

Which groundnut is best for oil extraction?

1. Consider the size of the peanut kernel. If the peanut kernel is too large, it won’t fit through the feed opening of smaller oil press machines. Conversely, if the kernel is too small, the downstream speed will be too high, which can hinder oil yield. .
2. Check if the peanut kernel is fresh. It’s essential that the peanuts used for oil extraction are not moldy, as moldy kernels contain aflatoxin, a potent carcinogen.
3. Examine the variety of peanut kernels. There are several types of peanuts, including ordinary peanuts, pearl peanuts, multi-grain peanuts, and dragon peanuts. The ordinary type is the most suitable for oil extraction, boasting an oil content of 52-54%.

How to start groundnut oil extraction business?

1. Conduct a thorough market analysis. It’s essential to determine if peanuts are cultivated in the area, assess the quality of the peanuts, understand the local demand for peanut oil, and evaluate the income levels of the population.
2. Select an appropriate location to set up a groundnut oil extraction business. After that, obtain the necessary business license from the relevant government department.
3. Buy groundnut oil processing machine equipment. If you want to start a peanut oil press factory, then a peanut oil press is not enough. You need a peanut shelling machine, peanut peeling machine, groundnut oil extractor, peanut filling machine, and other related equipment
4. Market your peanut oil. Finally, you need to find sales channels to sell your peanut oil.
