Abstract
The invention discloses a method for separating cotton linters and hulls from cottonseed hulls. The method comprises the following steps: 1, adding water to a cottonseed hull raw material for cleaning, wiping, and immersing the cleaned and wiped cottonseed hull raw material in a KOH solution for later use; 2, transferring cottonseed hulls and the obtained solution to a high temperature reaction kettle, boiling, adding an H2O2 solution in the boiling process, cooling to room temperature, and taking out the obtained reaction product; and 3, putting the reaction product in an oven, drying, beating by a juice machine, and screening by a sieve to obtain the cotton linters and the hulls. The method has the advantages of simple and easy production process, and strong practicality, and realizes low price, non-toxicity and innocuousness by using the KOH solution and the H2O2 solution in the production process in order to substantially reduce the cost; and the purified cotton linters and the hulls are separated from the cottonseed hulls, and the comprehensive utilization rate of the raw material and the added values of the product are greatly improved.
Description
Technical field
The present invention relates to a kind of processing method of cotton seed hulls, more particularly, to a kind of cotton linter and shell of separating from cotton seed hulls
Method.
Background technology
China is the maximum Chan Mian state in the whole world, country of consumption and importer.In recent years, send out with the swift and violent of cotton textile industry
Exhibition, market is continuously increased to cotton demand, 2011 annual 7941.7 ten thousand mu of national cotton cultivated areas, increases by 8.5% compared with last year；
Average 95 kgs/acre of per unit area yield, increases by 11.6%；2011 annual 754.8 ten thousand tons of national cotton total outputs, increase by 21.2%.With
The expansion of cultivated area, also increasing further, the comprehensive utilization how realizing cotton will become and study from now on for the yield of cotton
Emphasis.
Cottonseed separates through decorticator, and cotton benevolence is used for extracting oil, and remaining shell is exactly cotton seed hulls, also referred to as cotton skin.According to stripping
The type of shell machinery is different, cotton seed kind is different, the place of production is different, water content is different, peel off after broken cotton benevolence powder sieve degree not
On an equal basis.The size of the cotton seed hulls processing, color, velveteen length, the powder of benevolence containing cotton are also different.
At present, cotton seed hulls after treatment, still has 15%～40% cotton linter content not reclaim, edible for planting
Bacterium raw material and ruminant feed raw material, cause the wasting of resources.And cotton linter therein be produce cellulose esters, ethers and its
The important source material of his cellulose derivative, is widely used in the industries such as food, medicine, chemical industry, oil drilling, metallurgy.Extract cottonseed
Cotton linter in shell, has good economic, social and environmental benefit.Therefore, how to realize the efficiently comprehensive profit of cotton seed hulls high level
With being our problems in the urgent need to address.
Content of the invention
For above-mentioned prior art, the invention provides a kind of method separating cotton linter and shell from cotton seed hulls, its mesh
Be that cotton linter is separated with shell, obtain pure cotton linter and shell, realize the value of cotton seed hulls high level high-efficiency comprehensive utilization.
The present invention is achieved by the following technical solutions：
A kind of method separating cotton linter and shell from cotton seed hulls, is mainly achieved by following scheme：
(1) pre-process：Take cottonseed husk as raw material, add water and be stirred cleaning, extract standby after cleaning；By the cottonseed extracted
Shell concentration is 0.5%～5% KOH solution immersion 4～8h, standby；
(2) separating treatment：Step (1) gained cotton seed hulls and KOH solution are proceeded in pyroreaction kettle, stirs boiling, steam
Boil cooling after finishing, when being cooled to temperature for 90 DEG C about, add H2O2Solution carries out insulation reaction, when being cooled to room temperature afterwards,
Take out reactant, standby；
(3) cleaning, drying：Above-mentioned reactant is extracted, puts in baking oven and dry at 60～110 DEG C, carry out afterwards beating
Slurry, screening, you can obtain detached cotton linter and shell.
In step (2), described boiling temperature is 120～200 DEG C.
In step (2), described digestion time is 4～8h.
In step (2), described addition H2O2Concentration is 0.3%～1.5%.
In step (2), described addition H2O2Reaction time be 20～60min.
In step (3), the sieve of described screening is 20～40 mesh.
In step (1), the addition of KOH is the 5%～15% of amount of dry matter.
H is added in step (2)2O2Amount be dry 3%～10%.
Beneficial effects of the present invention are：
1. the present invention isolates pure cotton linter and shell from cotton seed hulls, and the cotton seed hulls of gained can make feed and eat
The raw material of bacterium, raw material comprehensive utilization ratio and added value of product increase substantially；
2. in production process, use KOH solution and H2O2Solution, cheap, nontoxic so that cost reduces significantly；
3. production process is simple, practical, meets the requirement of industrialization production.
