Description
Technical field
The invention belongs to the feed processing technology field, be specifically related to a kind of method of utilizing cassava starch dregs, manioc vinasse slag processing feed.
Background technology
In China south and South Asia ASEAN countries; Cassava all is to produce one of starch and the topmost raw material of alcohol; With cassava processing starch or (with) also have behind the alcohol a large amount of residue cassava starch dregs or (with) the vinasse slag, each with the cassava be raw material production starch or (with) enterprise of alcohol all can produce every year number with the fecula of kiloton even ten thousand tons, hundreds of thousands ton or (with) the vinasse slag.Slightly measuring and calculating just, annual cassava starch dregs that produces of China and vinasse slag total amount are at least more than five or six hundred ten thousand tons at present.Cassava starch dregs and vinasse slag also contain nutritional labelings such as a certain amount of starch and crude protein except that mainly containing a large amount of celluloses, still have higher nutritive value, can be used as animal-breeding feed.But because tapioca or (with) cassava starch dregs that produces of Alcohol Production enterprise or (with) the vinasse pulp water divides content higher, generally all can be between 85-90%, even higher; Both can't preserve for a long time, again can't long-distance transportation, still do not have mature and feasible comparatively in addition at present and can scale be processed into the method for feed; All cassava starch dregs or vinasse slag have only few part to be transported as fresh feed by near the raiser the enterprise season in production; And wherein the overwhelming majority all can't in time be handled and utilized, more can not with starch or Alcohol Production Synchronous Processing, cause cassava starch dregs or (with) the vinasse slag can only be discharged into earlier and deposit in the storage pool or stack with the stockyard; Time is long slightly; Just putrid and deteriorated giving out a foul smell can be taken place, grow a large amount of mosquitos and flies simultaneously, its feed value also can be lost thereupon; Both serious environment pollution caused the great wasting of resources again.
Can handle on environmental protection ground for cassava starch dregs and alcohol slag that will be so a large amount of, avoid environmental pollution, can its resource ground be utilized again, be developed to valuable feed, people have carried out a large amount of research and test, and have obtained some useful achievements.On February 9th, 2011 for example, Chinese patent just disclose the Cheng Guanwen application patent of invention " a kind of method of utilizing tapioca processing waste residue to prepare biological feedstuff " (publication number: 101965905A), disclose: " raw material is by following percentage batching: tapioca processing waste residue 50%-55%; oily chaff or wheat bran 20%-30%, corn flour 8%-10%, dregs of beans 8%-15%; ferment bacterium 0.1%-0.2%, brown sugar 0.2%, fish meal 2%-3%; urea 0.5%; calcium superphosphate 1%-1.5%, salt 0.1%, and copper sulphate, ferrous sulfate and zinc sulfate 105 gram/tons respectively; With above-mentioned raw materials mixing 10-15 minute, and the control moisture content was stacked anaerobic fermentation 2-3 days by wide 2-3 rice, high 1.5-2 rice bar shaped at 45%-50% after being mixed; Feed is processed in 55-65 ℃ of oven dry behind 55-65 ℃ of oven dry or extruder grain ".This method provides a kind of method with certain practical value for cassava starch dregs is prepared into feed; But also there is sizable deficiency in it, mainly is that production technology is too complicated, by too many with the feed supplementary product kind that relies on other high prices, amount is also bigger; Production cost is too high; Confined condition is too many, and operation easier is big, still is difficult to realize scale, minimizing environmental protection treatment; Be processed into to resource the feed that can preserve for a long time with long-distance transportation, the resource feed conversion of cassava starch dregs and vinasse slag still is badly in need of seeking more feasible method.
Summary of the invention
The objective of the invention is to overcome the deficiency and the vacancy of technical method in the present production practices, a kind of method of utilizing cassava starch dregs, manioc vinasse slag resource to be processed into feed is provided.
The objective of the invention is to realize like this: a kind of method of utilizing cassava starch dregs, vinasse slag processing feed; Comprise following processing step: cassava starch dregs, manioc vinasse slag are dewatered to moisture weight percentage 51-70%; Then with temperature oven dry more than 65 ℃; Its moisture is reduced to below 13%, is processed into feed or feedstuff.
Described cassava starch dregs, manioc vinasse slag dewater to moisture 51%-70% through once or once above dewatering process reach.
Described cassava starch dregs, manioc vinasse slag dewater and comprise that to the dewatering type of moisture 51%-70% employing mechanical dehydration, fermentation are dewatered, the airing dehydration.
Described cassava starch dregs, manioc vinasse slag dry to moisture below 13% through once or the stoving process once reach.
Described cassava starch dregs, manioc vinasse slag were dried before moisture is below 13% and are carried out the everfermentation PROCESS FOR TREATMENT.
Described cassava starch dregs, manioc vinasse slag dried before moisture is below 13% or after through extrusion process formation particle.
Described cassava starch dregs, manioc vinasse slag dry to moisture below 13% before a certain proportion of fill material of blending.
Described fill material is one or more the mixture in rice bran, system chaff, wheat bran, dregs of beans, grass meal, corn flour, ground rice, flour, tapioca starch, tea bran, peanut press pulp, dish bran, the paulownia bran.
Can also carry out earlier after the dehydration of described cassava starch dregs, manioc vinasse slag certain hour airing or air-dry after dry again; Or carry out the airing of certain hour or air-dry after the oven dry again, or carry out carrying out again after the prebake airing or the air-dry oven dry again of certain hour earlier.
By technique scheme, the beneficial effect that the present invention has is following:
1, the present invention is for cassava starch dregs, the manioc vinasse slag that is regarded as polluting waste by people carries out industrialization, the resource development and utilization has searched out a feasible approach always.
