Description
Technical field
The utility model relates to oilseed cold pressing expeller, more particularly, relates to screw oil expeller or twin-screw screw oil expeller.
Background technology
Along with the improvement day by day of material life condition, people are more and more higher to the requirement of food quality, and a tangible example is that the demand that does not apply the agricultural chemicals and the organic food of a large amount of chemical fertilizer is rolled up.Simultaneously, people whether " environmental protection " also keeps a close eye on especially for food processing technology.
At present industrial habitual system oil mode has milling process and solvent leaching method, grease processing textbook at classics [is edited as Y.H.Hui, " oil chemistry and the technology " of Bei Lei (the 5th edition, the 4th), China Light Industry Press, 69-72 (2001)] in, for obtaining higher oily yield, conventional milling process need heat oil plant usually, promptly so-called " steam and fry " or " modified " operation, can make protein denaturation in the oil plant through the processing of this operation, assemble with the microgranular oil droplet that is dispersed in the oil plant thereby make originally, and be easy to from the oilseed protein of sex change, be squeezed out.
Yet a big shortcoming of this method is, because after oil plant was heated, some oil-soluble impuritieses that contain in oil plant also can together be squeezed out as phosphatide, pigment etc., and make expressed oil must just can reach the standard of edible oil through refining treatment.And the process of refining can be followed processing such as acid, alkali, carclazyte decolouring and heating usually, thereby makes process can't reach the requirement of " environmental protection ".
In traditional milling process, also having a kind of is that the oil plant that will not pass through heat treated directly adopts screw oil expeller or twin-screw screw oil expeller to squeeze.Yet because the oil expression process is the process of a kind of high pressure and friction, along with the carrying out of oil plant squeezing, pressing bore temperature in the oil press can raise gradually, and finally is stabilized between 110-130 ℃.Following of this temperature press expressed oil can't satisfy directly edible quality standard requirement equally, and must after making with extra care, could eat.
In view of the above shortcoming of traditional milling process, in recent years, the exploitation of pressed oil technology and device and improvement have caused the attention of industry.
For example, Chinese utility model patent 02290849.8 provides a kind of low temperature screw oil expeller, and it comprises dog-house, and quality-adjusting device presses thorax, dregs of fat collecting chamber, oil cake outlet, spiral shaft and press for extracting juice cage.This patent is by cold press that vegetable oil material is peeled, and is set as the multistage different-diameter by pressing cage, and the press for extracting juice spiral shell series connection that screw spindle is made by the different pitch of more piece, various outer diameter constitutes.
The shortcoming of this low temperature screw oil expeller is that it has only done corresponding adjustment in shape in the pitch and the row of press for extracting juice of press for extracting juice spiral shell, and the screw oil expeller of the remainder of oil press and routine does not have any difference, and [Ni Peide writes, grease processing technology, Chemical Industry Press, Beijing, 122-129 (2003); What is conquered east is write, and grease is produced and process technology, Hubei science tech publishing house, Wuhan, 114-138 (1998)].Therefore, in the oil expression process, along with the prolongation of time, the friction of oil plant between shaft and press for extracting juice thorax may cause the rising of pressing temperature equally, thereby in fact can't guarantee cold pressing.The rising of pressing temperature then might cause various oil-soluble impuritieses in the sex change of oilseed protein and the expressed oil, as the rising of phosphatide, pigment equal size, thereby makes expressed oil might can't satisfy the quality standard of edible oil.
