Peanut kernels go through a series of pretreatment steps to produce peanut oil. The specific process is as follows:
Peanut kernels → cleaning → magnetic separation → stone removal → crushing → embryo pressing → steaming and frying → pre-pressing → steaming and frying → secondary pressing → filtering → deacidification and drying → canning
The cakes produced by the secondary pressing will be stored in the cake warehouse after cooling. The process is: secondary pressing → cake cooling → cake warehouse
1) Peanut Shelling Machine
This peanut shelling machine consists of a feed hopper, a grooved roller, a slatted concave plate, a fan, a specific gravity sorting screen, an air conveyor, etc. It has the advantages of compact structure, stable performance, good durability, large processing capacity, low power consumption, and easy operation. The shelling rate is not less than 95%.

2) Cleaning sieve
In order to achieve effective cleaning effects, ensure a good operating environment and production stability, and improve the quality of finished products, a high-efficiency vibrating screen is equipped in the process to clean up large and small impurities.

3) Magnetic separator
It is equipped with a non-powered magnetic separator, which is used to remove iron impurities in peanuts.

4) Gravity Stoner
A suction-type specific gravity stone remover is used to remove the side stones and side mud from peanuts.

5) Toothed Roller Crusher
To ensure that the peanuts can achieve the ideal effect during the subsequent softening and steaming process, a toothed roller crusher is used to evenly crush the peanuts into 4-8 pieces, so that the temperature and moisture of the peanuts can be evenly distributed during steaming and frying, which is convenient for subsequent pressing.

6) Steaming and frying pan
The function of the steamer is to adjust the moisture and temperature of the peanuts to a range suitable for pressing.

7) Embryo Press
The embryo press can prepare peanuts of a certain particle size into thin flakes of about 0.3mm. Its purpose is to extract the oil from the raw materials to the maximum extent in the shortest time during the leaching process, so that the residual oil in the meal is less than 1%.

8) Pre-press
This screw pre-press has a wide range of applications and can be used to press a variety of vegetable oils, including peanuts, rapeseed, soybeans, sunflower, etc. It uses a striping process and is suitable for the first pressing of materials with high oil content.

9) Screw oil press
This screw oil press is a popular product of the company, capable of pressing a variety of vegetable oils, including peanuts, rapeseed, soybeans, and sunflower. It utilizes a combination of round and row screws, equipped with micro-electric control, infrared heating, and multi-stage pressing capabilities. It can perform both hot and cold pressing, making it an ideal machine for oilseed processing.

10) Vertical leaf filter
The vertical vane filter is a highly efficient filtration system that uses a thick stainless steel mesh screen to remove both coarse and fine residues from the oil, with automatic deslagging. This filter is easy to operate and continuous, with minimal labor intensity, facilitating subsequent fine filtration.
