Description
Technical field
The invention belongs to cotton seeds manufacture field, and in particular to a kind of processing method of cotton seeds.
Background technology
After cottonseed is separated from cotton, the velveteen of many remainings is also attached with cottonseed surface, during planting with sowing machine, because
The velveteen on cottonseed surface winds mutually, hinders seed and is successfully spread out from seeder, has severely impacted mechanical planting, is
This is prior to seeding, it is necessary to which cottonseed is processed, and the velveteen of remaining is thoroughly peeled off from cottonseed surface.
Conventional technique is with dilute sulfuric acid or foamed acid processing technology at present.I.e.：Sulfuric acid solution stirs cottonseed, drying cylinder
With friction cylinder friction cottonseed after drying, any surface finish is then obtained, be suitable to the cotton seeds of mechanical planting.When acid solution is selected
Typically use following two techniques：(1) dilute sulfuric acid technique, short time spray is carried out using the acid solution of high concentration and excess to hair seed
Stirring is spilt, is then centrifuged for filtering off unnecessary acid solution, velveteen is sloughed by high temperature cabonization.This technique is simple and easy to operate, but easily
Cause seed damaged, residual acid is higher, typically 0.2% or so, more than GB.(2) foamed acid technique, in sulfuric acid concentration 6.0-
Foaming agent, activator are added in 7.0% solution, acid solution is covered on velveteen in the form of foam, urged by activator and oozed
Under effect and high temperature, acid solution carbonization velveteen, rubbed lint.Because strict control acid, to the seed hair for having knife wound and crackle
Bud rate influence is little, and seed breakage is low, processing cost is low, has the disadvantage that this process specifications is strict, and process technology standard is difficult to
Grasp, with the presence of residual suede, residual acid is whard to control, influences seed presentation quality.In sum：Two kinds of technique in production practices all
Insoluble defect is there is, causes that the seed percentage of A-class goods is not high, quality cannot be guaranteed.
A kind of processing method of cotton seeds is now provided, seed presentation quality, technical requirements be low, operation is simple with not influenceing
Single, safe and reliable advantage.
The content of the invention
In order to the processing method for solving existing cotton seeds is existed, influence seed presentation quality, technical requirements are high, operation
The low problem of complicated, security reliability, it is an object of the invention to provide a kind of processing method of cotton seeds, with not influenceing to plant
Low, simple to operate, the safe and reliable advantage of sub- presentation quality, technical requirements.
