Description
Technical field:
The present invention relates to a kind of deiinted cotton seeds processing technology method, particularly a kind of delinting method of cotton seed by using acid solution.
Background technology:
At present, mainly being divided into chemical treatment, physical treatment and Chemical Physics in the cotton seed lint processing at present combines and handles several modes.The physical treatment mode mainly is to adopt physical friction mode brute force that the velveteen on cottonseed surface is sloughed, the disclosed cotton seed linter of Chinese patent CN2157936, disclosed watt of brush of CN2349220 cotton seed delinter promptly belong to the equipment of this class technology, this kind technology is comparatively serious to the seed damage, seldom uses at present.Chemical mode then is to slough after adopting the velveteen charing of sulfuric acid with the cottonseed surface, but mainly is limited to manual operation, and work of treatment intensity is big, efficient is low, the quality control difficulty is big, only uses when the small lot seed treatment at present.
And to be Chemical Physics the combine processing mode of the main flow in scale seed processing; particularly just belong to this class as present foamed acid, excess acid cotton seed processing technology; with acid kind of seed surface being carried out shallow-layer earlier handles; by warm air drier, rubbing machine residual suede is ground off, the advantage that this processing technology combines preceding two kinds of technologies has become the main flow technology that present cotton seed is processed again.As the disclosed cotton seed excess acid direct heat drying de-linter equipment of Chinese patent CN1172700, the disclosed cotton seed foamed acid of CN2688029 lint equipment just belongs to the exemplary apparatus of this class process, and this class processing technology mainly comprises following process at present:
Adding acid mixes and stirs: the hair seed adds acid and mixes and stirs by agitator;
Dehydration: drying machine drying or elder generation re-use drying machine drying after centrifuge dries;
Friction: remove short flannel after the charing by rubbing machine;
Screening: obtain qualified seed through the sifting machine screening.
It is cotton seed hair seed to be presented to be provided with in the tank diameter that mixes and stirs impeller that cotton seed wherein adds that acid mixes and stirs, the impeller that mixes and stirs by agitator mixes and stirs propelling by force with the seed in the tank diameter, mix and stir impeller itself and mix and stir impeller and tank diameter between extruding all can cause the damage of certain brokenness to seed, influence seed germination rate.
Development along with agricultural planting technique, particularly new quality product kind is applied, seed usually is to valuate with grain, for adapting to the needs of precision drilling, just the processing of seed is had higher requirement, promptly require in process loss lower, therefore a kind of crudy better, the lower delinting method of cotton seed by using acid solution of seed injury tolerance is just arisen at the historic moment.
Summary of the invention:
The purpose of this invention is to provide better, the lower deiinted cotton seeds processing technology method of a kind of crudy, particularly a kind of delinting method of cotton seed by using acid solution to the seed injury tolerance.
Technical scheme of the present invention is: comprise following process at least: add acid and mix and stir, dewater, dry, rub, screen, its improvements are describedly to add acid to mix and stir technology as follows: cotton seed hair seed is presented in the rotary screen that is provided with charging aperture and discharging opening, the rotary screen inwall is provided with the screw propulsion impeller, and above-mentioned rotary screen bottom is immersed in the acid solution of acid bath, and described cotton seed hair seed is by the rotation of rotary screen and advance to discharging opening one end from rotary screen charging aperture one end finish cotton seed acid seed course of reaction under the promotion of screw propulsion impeller.
As improved technical scheme, above-mentioned dewatering process is as follows: adopt high frequency oscillation to take off the liquid method cotton seed is dewatered, the concussion frequency is 100～30000 times/minute, and preference is 100～3000 times/minute
As improved technical scheme, in the above-mentioned process, raw material between each process procedure is carried and is preferably all adopted no compression induced formula conveying mechanism, as adopt conveyer belt, induction type conveyer, preferably adopt the vibration-type conveyer, the as far as possible extruding friction between minimizing equipment and the seed is reduced to floor level with the seed breakage rate in course of conveying.
Compared with prior art, technology process method of the present invention is lower to the seed injury tolerance in process, and loss is lower, and crudy is better.
