Screw type oil machine oil press oil press machine  is used to both cold press and hot press many materials. It can be used to press various kinds of oil corps, like rapeseed, cottonseed, soybean, peanut, sesame seed, coconut, olive fruit, sunflower seeds, walnuts, almonds, tea seed, etc.

About hot and cold pressing

Hot pressing: Less pressing, higher oil yield, less oil residue in frying, saving time and effort, increased economic benefit. But without further processing of hot oil, the oil has a very dark color, and contain a high acid value.

Cold pressing: Make sure that all kinds of nutrition in the materials are not been damaged and increase times of pressing, reduce the oil output, increase the residual oil in the cake, increase the power consumption greatly, and reduce the economic benefits. But cold pressing can keep the clear color of oil.

Principle and Structure of oil press machine/ seeds cold oil extraction

Screw expeller pressing is to separate the oil from oil bearing materials by the pressing power which comes from the change of chamber volume, drive from screw worm, resistance of curve teeth at press rings and extrusion friction between oil materials. Under the big pressure created in press chamber, the oil can be discharged from gap of press bars and oil trough of press rings. Either big scale and small scale of screw oil expeller, they have similar theories in screw expeller pressing. Because the screw type seed oil expeller is mainly used by extrusion theory, so it is also called as oil extruder or oil extrusion process.
