Compared with other oil press, auto hydraulic oil press is the easiest one in operation, featured by highest oil yield and the wearing parts are most durable. The hydraulic oil press is widely used to produce oil from sesame seeds, peanuts, flax, rapeseed, sunflower seed, cotton seed, soybeans and other oil crop seeds. Hydraulic oil press is more suitable for household and small size plant.
Hydraulic Oil Press Features
1. Energy saving: the hydraulic oil press can save 40% energy than other oil press machine with the same production capacity.
2. High oil yield: The normal oil yield is 2-3points higher than that made from the old-fashioned oil press machine.
3. Labor saving: this oil press is featured by easy operation, one person is enough.
4. Pure and high quality oil: the oil quality pressed by hydraulic oil press can meet the health and quarantine standards.
Hydraulic Oil Press Working Principle
The oil materials among screw threads are propelled forward when the pressing screw rotates. The space between pressing chamber and pressing screw is gradually reduced, and the oil material density increases, so the pressure is gradually increasing. For the friction of oil material particles, oil material and machine parts, it generates heat. The pressure and heat breaks the oil material histiocytes, the oil overflows from the oil lines. And the oil cakes are propelled out from the cake head and cake mouth. The vacuum pump pumps out the air from the bucket when the overflowing oil flows through the oil plate onto the oil bucket. Negative pressure forms in the bucket, so the oil is pumped into the bucket through the filter cloth. The oil residues are staying on the filter cloth, thus the oil is pure.
