The commercial cooking oil making machine is a mechanical device that uses mechanical external force to extract oil from oil crops (such as peanuts, soybeans, rapeseed, sesame, etc.). According to different working principles and processes, it is mainly divided into two categories: hydraulic oil press and screw oil press.The seed oil press machine is widely used in family workshops, small and medium-sized oil factories and industrial production.
Raw Materials For Oil Pressing
There are many raw materials that can be used to press oil. Such as soybeans, sesame seeds, peanuts, sunflower seeds, pepper seeds, rice bran, tea seeds, oil palm seeds, olives, coconut fruits, palm fruits and other granular oils. It can also be used for powdered oils such as rice bran and corn germ and small wild plant oils such as safflower. These raw materials for oil pressing are relatively nutritious. Among them, soybeans, peanuts and sesame are the raw materials often used in oil pressing, and the oil content is relatively high.
Cold Pressing VS. Hot Pressing
Cold pressing is a process in which the oil is sent to a cooking oil extraction machine for pressing at a temperature below 60°C without being heated or cooled before pressing. It retains the natural flavor and color of the oil, but the oil yield is low and the selling price is generally high.
Hot pressing is to wash the oil first, crush it, and then heat it at high temperature to make a series of changes inside the oil to adapt to pressing and increase the oil yield.
Screw Oil Press Machine Introduction
Screw oil press machine is a widely used equipment in oil pressing. It can be used for a wide range of raw materials. It has a large output range and can be applied to large and medium-sized enterprises such as families, workshops, and oil mills. The machine achieves the pressing and extraction of oil through the rotation of the screw, friction, and heat generated by thermal energy. This process helps to efficiently extract vegetable oil from oil while maintaining the natural characteristics of the oil. Therefore, the scope of use of screw oil press is very wide and is loved by customers.

Oil Screw Press Machine Capacity
The models of oil screw press machine are divided according to the screw diameter. For example, the 6YL-60 model has a screw diameter of Ф55mm and an output of 40-60kg/h, which is very suitable for small-scale production.
The 6YL-70 model has a production capacity of 50 – 70 kg/h, which can meet the needs of medium-sized oil mills. The 6YL-80 model has a production capacity of 80 – 120 kg/h, with high production efficiency, suitable for medium-sized and large oil mills or small processing plants. The 6YL-100 model has a production capacity of 150 – 230 kg/h, while the 6YL-125 model has the highest production capacity, up to 300 – 350 kg/h, which can meet the needs of large-scale production. Users can choose the appropriate model according to their production scale and market demand.
Hydraulic Oil Press Machine
Hydraulic oil press is a purely physical pressing method. It does not generate temperature during the pressing process and does not destroy the organic components of the oil. The pressed oil is of good quality and has few impurities. It is particularly suitable for some oils with high oil content (such as sesame, almonds, pine nuts, peanuts, walnut kernels and some animal oils) and materials that must be processed by cold pressing (such as chemical raw materials and pharmaceutical raw materials).

The output of hydraulic oil press varies depending on the model (pressing chamber diameter), raw material type, pressing process (hot pressing/cold pressing) and equipment power. For example, for the 6YZ-150 model, the diameter of the press chamber is Ф150mm, and the output is 15-30kg/h.
Differences Between Screw And Hydraulic Oil Press
1. Oil pressing method
Hydraulic oil press is an oil pressing equipment that squeezes oil based on the principle of hydraulic power transmission.
Screw cooking oil making machine is a pressing equipment that forces the feed through the screw shaft, generates high temperature and high pressure under the rotation and extrusion with the pressing ring, so that the oil is crushed and squeezed out of the oil and the cake is produced.
2. Oil quality
Hydraulic oil press does not generate temperature during the pressing process, does not destroy the organic components of the oil, and the oil squeezed out is of good quality and has few impurities.
Screw oil press generates high temperature during the oil pressing process, which will destroy the organic components of the oil. During the rotation and friction process, some oils with high oil content will produce sludge and be squeezed out of the pressing ring, and the impurities and content in the oil are higher.
3. Recycling rate of cake residue
The cake squeezed out by hydraulic cooking oil press machine is a round cake. Since there is no overheating phenomenon during the static pressing process, the protein of the cake is fully retained, and the nutritional value is high. It can be used as feed or high-grade fish bait.
The oil cake squeezed out by the screw oil press is a flaky cake. During the oil pressing process, high temperature will be generated due to mechanical friction, and the nutritional value such as protein will be lost. It can only be used as waste or leaching raw materials.
4. Whether filtering is required
The hydraulic oil press is a typical cold pressing process. The oil squeezed out is original in color and taste, and can be eaten directly without filtering.
The screw oil press generates high temperature during the oil pressing process, which will produce acid substances such as phosphoric acid, and the color will be black. The squeezed oil needs to be filtered.
