Screw press is a machine that uses the function of mechanical screw press to extrude oil by increasing temperature and activating oil molecules. The whole set of equipment includes: screw oil press, hydraulic oil press, centrifugal oil filter, frying pan, etc.
A good screw oil press can save users a lot of trouble in oil processing. When buying the machine, first check whether the appearance of the screw oil press is flat, check whether the parts of the machine are missing, and then turn the large belt pulley by hand to make it rotate a few more turns, check whether there are iron blocks and other foreign matters in the press cylinder, and pay attention to whether the gear engagement in the gearbox is normal.
Different oils have different pretreatment process requirements. The working principle of the screw oil press is that when the oil press equipment is running, the power is transmitted to the main shaft after deceleration, the oil pressing screw installed on the main shaft rotates, and the oil between the threads moves forward continuously.
As the space between the oil press and the oil screw is gradually reduced, the oil density increases and the pressure increases gradually. In the process of pressing, friction occurs between oil particles and between oil and parts to produce heat, which constitutes two major factors of pressure and heat in the process of pressing oil, and destroys the cell structure of oil tissue. The oil overflows from the oil line and the cake is pushed out between the oil cone and the cake outlet.
When the spilled oil flows into the oil filter barrel through the oil pan, the vacuum pump will extract the air in the barrel, a negative pressure is formed in the barrel, the oil is pumped into the barrel through the filter cloth, and the oil residue is isolated on the filter cloth. At this time, pure oil is obtained.
High oil yield of oil press equipment: the spiral oil press adopts directional oil pressing method, which is pushed for many times and pressed for 1 ~ 2 times, and the oil yield is continuously improved.
Output advantages of oil press equipment: strengthen the feeding device, strengthen the pressing propulsion speed, and greatly improve the processing raw materials.
Automatic temperature control device of oil press equipment: use electronic program, scientific heating and full-automatic temperature control pressing.
Automatic filtering of oil pressing equipment: using air hydraulic principle, vacuum separation technology and equipped with filter, the quality and color of oil are greatly improved.
The equipment of oil press is simple: the full-automatic spiral oil press has fine structure, less land and simple and convenient operation.
