Function introduction of screw oil press:
1.The screw oil press is a common oil extraction equipment. It has the characteristics of simple structure, easy use, low noise, low power consumption, and high oil yield. It is suitable for use by small and medium-sized processing plants and individual professional households.
2.The working principle of the screw oil press is to continuously push the material embryo inward through the rotation of the pressing screw and press it in the pressing chamber. Since the material embryo is pressed in a moving state in the oil press, a large frictional resistance is generated between the material embryo and the pressing snail, the material embryo and the pressing chamber, which causes relative movement between the material embryo particles and improves the pressing efficiency. .
3.Screw oil presses can be divided into hot presses and cold presses. Hot presses usually need to fry the oil before pressing, while cold presses do not need to heat the oil. In addition, the screw oil press can also be customized according to the type of oil pressed crops, the workload of the oil press, the diameter of the screw of the oil press, the number of crops pressed by the oil press, the degree of automation of the oil press and the configured oil filter. principles and so on.
4.When installing and using the screw oil press, you need to pay attention to leaving enough space around it for the staff to operate. After the machine is installed, a 0.5-1m deep ground wire needs to be placed 3-5m away from the machine before it can work.
What materials is the screw oil press suitable for?
This screw oil press is suitable for pressing peeled rapeseed, peanut kernels, soybeans, olives, walnut kernels, corn germ, rice bran, tea seeds, safflower seeds, sea buckthorn seeds, neem seeds, rubber seeds, pepper seeds, and tomato seeds. , watermelon seeds, grape seeds, flax seeds, evening primrose, pepper seeds, castor seeds, citrus seeds, cocoa beans, coffee beans, perilla, almonds, peach kernels, rose hips and other vegetable oils.

The product features of screw oil press are as follows:
1. Low-temperature pressed oil is light in color and rich in nutrients. Pure natural oil can be obtained through sedimentation and filtration, saving refining costs and reducing refining consumption.
2. The protein in the low-temperature pressed cake is less damaged, which is beneficial to the full utilization of oil protein.
3. The pressing temperature is low (normal temperature 10ºC~50ºC).
4. During the pressing process, the oil does not come into contact with any solvent, acid, alkali, bleaching soil, or chemical additives. The processed oil and cake have little loss of nutrients and trace elements, and the cake has a high protein content.
The screw oil press's methods of squeezing various oils are as follows:
1. Sesame: Before pressing, fry the seeds until they are light gray and appear to burst. When you pinch the seeds with your hands, oil will flow out. There is basically no residue in the oil. The cake will be in the shape of a long strip. Squeeze it dry.
2. Rapeseed: Because the moisture content of the raw materials is different in the north and the south, add 4-6% before frying. In the south, add 4-6% (depending on the moisture content of the raw materials). First stir-fry the rapeseed over high heat until it is hot to the touch and starts to make a popping sound. So far, the color is brownish red.
3. Peanut kernels: Soak the peanut kernels before frying the seeds. During the process of frying the seeds, an appropriate amount of water should be added to keep the kernels good softness and sufficient moisture. Fry the kernels until they are eight ripe.
4. Cottonseed kernels: Before pressing, fry the oil until it is light yellow, the temperature is 120-130 degrees, and the cake thickness is 1-1.5mm (the moisture content in the south and north is different, so control the moisture appropriately).
5. Soybeans: Stir-fry until bursting before pressing, temperature 120-130 degrees, cake thickness 0.7mm. Squeeze it dry once, but the cake will be too burnt, resulting in a great loss of protein. Generally, the process of squeezing dry twice is used.
