Latest technology energy-saving cold press combined screw automatic oil press

This cooking oil extraction machine is suitable for rapeseed, peanut, soybean, sunflower, rapeseed, sesame seed, tea seed, walnut, corn germ, and so on.

Raw material

the plant is suitable for Soybeans, peanuts, corn, flax, linseed, tea seed(camellia seed), sesame,walnuts, rapeseed, grape seed,castor, sunflower, cottonseed etc.

Working priciple

Generally, sunflower oil production line does the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extracting crude oil from these seeds, and then further refining the oil obtained before packaging.
Cleaning the Seeds
The harvested oil-bearing seeds are passed over magnets to remove any metal traces, and other impurities are being got rid of by cleaning sieve and destoners. Then the outer covering (hulls) of the seeds are removed to obtain pure seeds.
Grinding the Seeds
The de-hulled seeds are ground into coarse meal to provide a larger surface area to be pressed. Hammer mills or grooved rollers are used to crush the coarse meal into uniform fine particles. Then the meal is heated to enable oil extraction, though impurities are released with oil during this process and such impurities should be removed before the oil is declared edible.
Pressing
The heated meal is fed into a screw oil press which progressively, at the same time, the oil is squeezed out through the slots in the barrel and recovered.
Refining of the Oil
Oil refining involves removal of the bitterness, color, and odor. First, the oil is heated at temperatures between 40 0C and 85 0C. Then it’s mixed with an alkaline substance like sodium carbonate or sodium hydroxide. The oils are degummed by treating them with heated water at temperatures between 85 0C and 95 0C or with acidified water. This precipitates out most of the gums usually phosphatides. Then centrifugation is done to remove the dregs.

Advantage

Advanced motor and gear
Toppest gears and motors in domestic market
Manufactured by Liuhui factory, one of the most famous heavy industry bases in China. Machines manufactured by it in better quality and lower price.
High-level screw rings
Adopted advanced rings.
Rings can help achieve higher extracting efficiency, more durable than plates. Plates machine will be easily broken, also lower extracting rate.
Strong and reliable
Carbon steel, thickness of steel can reach 3mm, much heavier than any other factories’ machine proving better material and quality, which can help to achieve longer service life.
High oil yield
low residual in cakes, generally under 7%. Other brands usually about 10%. And also, because of the temperature in barrel of our machine under 80 degrees, the protein content in cake is much more higher.
