On August 30, 2023, Guangdong Pangdaxi Yuexi Construction Engineering Co., Ltd. ordered Huatai Group's 15T peanut oil extraction and 10T cold filter projects to start delivery.

Peanut is a very common food, and it can always be seen in our daily life. Whether it is fried peanuts made into dry goods or deep-processed peanut oil and peanut butter, they are very popular. The peanut ripening season is generally from August to October. During this time period, manufacturers of peanut products are busy, and peanut oil factories are no exception. Some oil factories will replace or purchase new equipment in order to expand production. More is the screw press. Because the oil content in peanuts is rich, up to about 50%, and the peanut oil squeezed by a screw press can achieve good production results.

The peanut oil screw press machine is mainly composed of five parts: hopper, gear box, press chamber, press screw and frame. Among them, the pressing screw is the key to the whole peanut oil screw press, and the selection of its material will affect the quality and service life of the printing machine. The technological process of extracting peanut oil by screw oil press: the processed oil is transported from the hopper to the press chamber, and the raw material embryo is continuously pushed inward by the screw to press, and the raw material is continuously pressed in the press chamber of the screw oil press. In the movement, the relative movement between the raw materials will generate friction, and the oil will also generate friction between the screw and the squeeze chamber, thereby generating heat.

At the same time, the diameter of the root circle of the pressing snail gradually becomes thicker from the inside to the outside, and the pitch of the screw gradually decreases. Therefore, when the pressing snail rotates, the thread enables the material embryo to be pushed forward and turned outward, close to the thread of the pressing snail. The material layer on the surface rotates with the press shaft, but the volume in the press chamber decreases continuously, so that the oil is subjected to a strong extrusion force. Peanuts are subjected to high temperature and high pressure in the screw press, and the protein in the oil is denatured by heat, and the plasticity of the embryo becomes larger but the viscosity decreases, so that the oil in the oil is precipitated and a good oil yield is achieved. Therefore, whether it is a peanut oil factory or an oil mill, they will choose a screw press machine when processing peanut oil.

Advantages of pressing peanut oil with screw press:

1. The protein content of the peanut cake after oil extraction is as high as 60%, which contains 8 kinds of amino acids needed by the human body and is a complete protein;

2. Peanut oil is a non-drying oil and contains a lot of fatty acids. Among them, unsaturated fatty acids are the main ones, which can be processed into high-grade edible oils such as salad oil, fragrant peanut oil, and pure peanut oil.

3. The roasted peanuts emit a pleasant and special fragrance, and its volatile fragrance is rich in more than 230 kinds of components, with complete color, fragrance and rich nutrition.

Why Peanut Oil Needs Cold Filtration:

Peanut oil cold filtration is to filter the crude oil squeezed by the peanut oil press, remove the fat contained in the crude oil, and reach the second-class edible oil standard stipulated by our country. Compared with the traditional hot filtration process, the peanut oil cold filtration process has the following obvious advantages:

1. Precipitation at low temperature, the separation of impurities is more thorough.

2. Avoid the problems caused by the oxidation and corrosion of oil at high temperature, so that the oil can maintain a high quality.

3. Reduce the multi-step operations required in the traditional thermal filtration process and reduce production costs.

4. The purification effect is better, which can improve the quality of oil and increase sales.
