Introduction of the oil press
Hydraulic oil presses are characterized by low temperature, high quality, and small batch production, making them suitable for high-end oil products. Screw oil presses are mainly divided into semi-automatic and fully automatic types, both of which are characterized by continuous, high-efficiency, and large-scale production, making them suitable for large-scale oilseed processing.
Differences in working principles
A screw oil press primarily works by using the rotation of a screw shaft to reduce the volume within the pressing chamber, squeezing and grinding the oil to expel it. A hydraulic system generates pressure that forces the oil through a piston.

Applicable raw materials
Screw oil press
Oil with medium oil content or requiring large-scale production, such as soybeans, rapeseed, cottonseed, etc. | Oil with high oil content and high quality requirements, such as olives, walnuts, sesame, etc.
Hydraulic oil press
Oils with high oil content and high quality requirements, such as olives, coconut oil, walnuts, and sesame oil
Difference in production efficiency
Screw oil press
Strong continuous operation capability, suitable for large-scale industrial production, and high production efficiency
Hydraulic oil press
A single press takes a certain amount of time and is relatively more suitable for small and medium-sized production
