The Pressing Method of Screw Oil Press Machine.
The pressing method has a long history. Its process is relatively simple. After the raw materials are steamed and fried, the oil is squeezed out of the oil using mechanical methods.
The ancient pressing method requires heavy physical labor from the operators. The residual oil content in the extruded oil residue (oil cake) is quite high, thus wasting extremely precious oil resources.
The modern pressing method is an industrialized and automated operation. Compared with old-fashioned equipment, the normal oil yield can be 2 to 3 percentage points higher, and an average of 2-6 more pounds of peanuts can be produced for every 100 pounds of peanuts processed. The economic benefits throughout the year are very high. considerable.
According to the pretreatment of the pressed raw materials, there are cold pressing method and hot pressing method, also called cooked pressing method.
Cold pressing means that the raw materials are directly put into the oil press to squeeze out the oil without roasting or steaming. In this method, the color of the oil is relatively lighter and brighter, but the oil yield rate is low, and the oil taste is not strong and mellow. .
Ripe pressing requires the oil crops to be dried before pressing. The purpose is to reduce the moisture content of the raw materials and increase the activity and fluidity of the oil molecules, thereby increasing the oil yield and ensuring the aroma and flavor of the oil. But it also destroys the chemical composition of the oil, causing the oil to become darker.
Ⅱ. The process of oil being squeezed out.
when the oil enters the pressing chamber of the oil press, the pressure increases as the pressing chamber rotates. The principle of multi-stage advancement and gradual pressurization is adopted to rapidly increase the pressure in the pressing chamber, causing the oil to be fissured and separated at one time, automatically controlling the pressing temperature and moisture, directly softening the oil and activating the grease molecules, and the pressing is stable, and the oil is squeezed out in one go, which greatly improves the efficiency of the press. The oil yield rate.
The oil press produced by BTMA is made of high carbon steel, which is quenched at high temperature and heat-resistant. It has high hardness, strength and wear resistance. It is suitable for continuous operation under high temperature and high pressure, which increases the service life of the oil press and can be used for a long time. For decades. And our screw oil press is a multi-purpose machine that can press more than 30 kinds of oil crops such as peanuts, flax, sesame, rapeseed, sunflower, cottonseed, and soybeans. Multi-stage pressing, squeeze everything in one go.
In short, the pressing method of oil press needs to be determined based on the raw materials you use and your needs. Different raw materials are suitable for different pressing methods. What's more important is that you choose a good oil press, and BTMA Company is your best choice.
