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, relate in particular to a kind of from cotton seed hulls the method for separated cotton linter and shell.
Background technology
China is maximum Chan Mian state, country of consumption and importer of the whole world.In recent years, along with the fast development of cotton spinning industry, market constantly increases cotton demand, and 2,011 7941.7 ten thousand mu of annual national cotton cultivated areas, compared with increasing by 8.5% last year; 95 kgs/acre of average per unit area yields, increase by 11.6%; 2011 754.8 ten thousand tons of annual national cotton total outputs, increase by 21.2%.Along with the expansion of cultivated area, the output of cotton is also in further increase, and the comprehensive utilization that how to realize cotton will become the emphasis of research from now on.
Cottonseed is separated through decorticator, and cotton benevolence is for oil expression, and remaining shell is exactly cotton seed hulls, also claims cotton skin.According to peeling off mechanical, type is different, cotton seed kind is different, the place of production is different, moisture is different, peel off after the broken cotton benevolence powder degree of sieving not equal.The size of the cotton seed hulls processing, color, velveteen length, also different containing cotton benevolence powder.
At present, cotton seed hulls after treatment, still has 15%～40% not recovery of cotton linter content, for planting edible fungi raw materials and ruminant feed raw material, causes the wasting of resources.And cotton linter is wherein the important source material of production of cellulose ester class, ethers and other cellulose derivatives, is widely used in the industries such as food, medicine, chemical industry, oil drilling, metallurgy.Extract the cotton linter in cotton seed hulls, there is good economy, society and environmental benefit.Therefore, how realizing the high value high-efficiency comprehensive utilization of cotton seed hulls is our problem in the urgent need to address.
Summary of the invention
For above-mentioned prior art, the invention provides a kind of from cotton seed hulls the method for separated cotton linter and shell, its objective is cotton linter separatedly with shell, obtain pure cotton linter and shell, realize the value of the high value high-efficiency comprehensive utilization of cotton seed hulls.
The present invention is achieved by the following technical solutions:
A method for separated cotton linter and shell from cotton seed hulls, is mainly achieved by following scheme:
(1) preliminary treatment: get cotton seed hulls raw material, add water and carry out stirring and washing, extract standby after cleaning; The KOH solution that is 0.5%～5% by concentration by the cotton seed hulls of extracting soaks 4～8h, standby;
(2) separating treatment: step (1) gained cotton seed hulls and KOH solution are proceeded in pyroreaction still, stir boiling, cooling after boiling, when being cooled to temperature and being 90 ℃ of left and right, add H
2o
2solution carries out insulation reaction, while being cooled to room temperature afterwards, takes out reactant, standby;
(3) cleaning, drying: above-mentioned reactant is extracted, put into baking oven and dry at 60～110 ℃, pull an oar afterwards, screening, can obtain separated cotton linter and shell.
In step (2), described boiling temperature is 120～200 ℃.
In step (2), described digestion time is 4～8h.
In step (2), described in add H
2o
2concentration is 0.3%～1.5%.
In step (2), described in add H
2o
2reaction time be 20～60min.
In step (3), the sieve of described screening use is 20～40 orders.
Beneficial effect of the present invention is:
1. the present invention isolates pure cotton linter and shell from cotton seed hulls, and the cotton seed hulls of gained can be done the raw material of feed and edible fungus, and raw material comprehensive utilization ratio and added value of product increase substantially;
2. in production process, use KOH solution and H
2o
2solution, cheap, nontoxic, cost is reduced greatly;
3. production process is simple, practical, meets the requirement that industrialization is produced.
