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, specifically refer to that 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 is completed respectively in two devices.What for example have the people to adopt 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 ", what this patent adopted the mode of whole process spray to realize respectively cottonseed in two leachers proposes oil and gossypol processing, but this dephenolizing process must be used the high concentration methanol more than 95%, existence is because the dephenolization effect that adopts high concentration methanol to bring is poor, 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 be also 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 the methyl alcohol that can adopt lower concentration, realized blanking twice with three dephenolizing extractors, dephenolize is more thorough, yet, this cottonseed is carried oil and phenol removal need complete in two kinds of equipment, use equipment is many, exist 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 by what complete cottonseed after 6# solvent oil and methanol mixed in a set of traditional leaching device, although the method is invested less, but because two kinds of solvent make 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 efficiency 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 someone propose in a set of traditional leaching device to add in two steps 6# solvent and methyl alcohol to carry out cottonseed carry oil and phenol removal, as patent of invention that on February 13rd, 2008, publication number was CN101121744 discloses a kind of " extraction method for dephenolize cotton seed protein ", what the mode of the spray adopted in this patent whole process was carried out cottonseed proposes oil and gossypol processing, yet this patented method is carrying out when cotton seed dephenolization is processed still using the high concentration methanol more than 95% could realize spray, this patented method exists in 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
