For a long time, because cooking oil industry of our country has no market access system, edible vegetable oil production standard is lower, many cooking oil manufacturing enterprises were set up, this caused the good cooking oil and bad cooking oil are intermingled. Now, with the performing of new country standard of cooking oil, edible oil production adopted market access system, to the effective cooking oil brand market expansion provided the opportunity. The traditional oilseed press has many disadvantages, such as the unreasonable structure, low oil yield, mechanical wear easily, can't the continuous production, low output, poor mechanical quality, the service life is short, unsatisfied performance, low profits, separated mechanical and electrical, more hidden danger of accident, need more operator, time consuming, poor hygiene environment, oil quality is no guarantee to the standards. Now there is a better choice for us: screw oil press.The processed oil materials get into the pressing chamber from the hopper when strat operating the screw oil press. The spiral turn make the material by the embryo to promote constantly squeezing. Because of material embryos in the oil press in the chamber is in motion state, under the high pressure of the chamber and the condition of material embryo and squeezer, material embryo and squeezed between bore produced great friction resistance, therefore it will make friction between the material embryos micro material, cause relative motion. On the other side, screw pitch is diminishing due to the root of squeezer diameter will become thick gradually, so thread material that can be hard embryo forward when squeezer turns, and to turn the can, close to the surface of the thread squeezer material layer also twirl with the rotation axis at the same time.
So each embryo particles material within the chamber will be twirling at the different speed, but the same direction, and between the micro particles there also exist relative motion. The heat produced by the friction can meet the demands for quantity of heat of press in the process operation, help to make materials in the embryo protein denaturation, destroy the colloid, increase the plastic, but also reduce the separation oil viscosity easy to some, and improve the yield efficiency of sesame oil press, thatfrom the park row gap and a row of aperture outflow have the oil squeezing out material.
The cold press expeller has many advantages, such as science design, reasonable structure, easy operation, safety stable, adopts full automatic device, from feeding to the finished product it needs only a few minutes. The screw oil press adopts high carbon steel that through the high frequency quenching, heat treatment, has high hardness and strength, good abrasion resistance, high temperature and can adapt to high pressure continuous work, improve the service life of the screw oil press, service life dozens of years. Using infrared temperature control system, the automatic control temperature and moisture squeeze, make oil directly to soften grease activated molecular, squeezing stability, greatly increasing the yield efficiency.
