Description
Technical field
The present invention relates to the cottonseed processing processing technology field, relate in particular to a kind of cottonseed and carry oil and phenol removal, refer to that specifically a kind of cottonseed carries oil, dephenolization treating method and device.
Background technology
At present cottonseed carry oil, dephenolize technology more feasible single stage method and two kinds of methods of two-step approach are arranged.
Two-step approach refers to the oily operation of carrying of cottonseed and phenol removal process are finished respectively in two devices.What for example have that the people adopts in two leachers that the spray mode carries out respectively cottonseed carries oil and phenol removal.The patent of invention that on July 28th, 2010, publication number was CN101785527A discloses " preparation method of a kind of dephenolization cottonseed protein and raffinose ", this patent adopts the mode of whole process spray to realize respectively the oily and gossypol processing of proposing of cottonseed in two leachers, but this dephenolizing process must use the high concentration methanol more than 95%, and existence is poor because of the dephenolization effect that adopts high concentration methanol to bring, methyl alcohol makes the problems such as protein denaturation; In addition, the patent of invention that August 1 calendar year 2001, publication number was CN1306078 also discloses " a kind for the treatment of process of cottonseed ", this patent also be adopt that two-step approach carries out cottonseed carry oil and phenol removal, the first step is carried oil with the spray-type leacher, second step soaks dephenolize with three dephenolizing extractors, the advantage of the method is to adopt the methyl alcohol of lower concentration, realized blanking twice with three dephenolizing extractors, dephenolize is more thorough, yet, this cottonseed carries oil and phenol removal needs to finish in two kinds of equipment, and use equipment is many, exists investment large, the installation load is large, the shortcomings such as complex process and tooling cost height.
Single stage method also claims mixed solvent method, the patent of invention that on May 24th, 2006, publication number was CN1775061 discloses " method of One-step production dephenolized cotton protein ", adopt in this patent and carry oil and phenol removal with what in the traditional leaching device of a cover, finish cottonseed after 6# solvent oil and the methanol mixed, although the method is invested less, but because two kinds of solvent so that in the dregs of rice Residual oil higher, and adopt its technique of the method to determine to adopt the above methyl alcohol of high density 〉=95% and the merging of 6# oil miscible solvent to carry out the spray mode and carry oil and phenol removal, the dephenolize efficient of high concentration methanol is low, methyl alcohol and cotton seed embryo piece are oversize duration of contact, thereby cause the problems such as the poor and protein denaturation of oil quality is serious, greatly reduce the nutritive value of product.
At present also the someone proposes to add in two steps in the traditional leaching device of a cover that 6# solvent and methyl alcohol carries out cottonseed carries oil and phenol removal, a kind of " extraction method for dephenolize cotton seed protein " disclosed such as the patent of invention that on February 13rd, 2008, publication number was CN101121744, what the mode of the spray that adopts in this patent whole process was carried out cottonseed proposes oil and gossypol processing, yet this patented method is carrying out still must using when cotton seed dephenolization is processed the high concentration methanol more than 95% could realize spraying, and this patented method exists in the cotton dregs Residual oil higher too, dephenolization effect is poor, methyl alcohol makes the problems such as protein denaturation is serious.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of new carrying is provided oil is effective, dephenolize thoroughly, effectively reduces the cottonseed protein sex change and invest the cottonseed little, that production cost is low and carry oil, dephenolization treating method and device.
