Abstract
The invention discloses a biological compound enzyme biochemical agent and a method for preparing biological straw paper pulp by using the same. The biological compound enzyme biochemical agent is prepared by mixing the following components in percentage by weight: 50-60% of corn flour, 2-8 parts of molasses, 15-25 parts of yeast, 10-20 parts of cellulose and 10-20 parts of saccharifying enzyme. The method for preparing the biological straw paper pulp by using the biological compound enzyme biochemical agent comprises the steps: triturating straws; mixing the biological compound enzyme biochemical agent, water and the crushed straws; fermenting; and producing paper pulp, and the like. The biological compound enzyme biochemical agent and the method for preparing the biological straw paper pulp by using the same have the effects that the pulp preparation process is clean; the production cost is reduced; woods are replaced with the straws of crops, so that wastes are turned into wealth, and the ecology is protected.
Description
Technical field
The present invention relates to a kind of biological complex enzyme biochemical agent and for the preparation of the method for straw biological paper pulp.
Background technology
The agricultural straw resource of China is very abundant, produces every year more than 5.7 hundred million tons, according to interrelated data, shows, China wastes stalk more than approximately 2.5 hundred million tons every year.Yet, as these resources are turned waste into wealth, for biological paper pulp, produce, replace traditional timber papermaking, reduce papermaking cost, tool is of great significance.In addition, traditional paper technology is high temperature, high-alkali, autoclaving method, belongs to high pollution industry.
Summary of the invention
The object of the invention is to adopt in order to overcome existing issue biofermentation technique that thereby a kind of biological complex enzyme biochemical agent is provided and for the preparation method of straw biological paper pulp.
For achieving the above object, the technical scheme providing is:
A biochemical agent, by following raw materials according by weight percentage composition mix and to form:
Corn flour 50～60 molasses 2～8 yeast 15～25
Cellulase 10～20 carbohydrase 10～20.
Optimum ratio scheme:
Corn flour 50 molasses 5 yeast 15
Cellulase 15 carbohydrase 15.
Biological complex enzyme biochemical agent, for a preparation method for straw biological paper pulp, comprises the following steps:
A, first by Mechanical Method, Straw Kneading is broken, is refined to 1.5-2 millimeters, makes crushed straw aggregate, standby;
B, biological complex enzyme biochemical agent is carried out to premix in ratio separately, then with 50 times of water purification mixing and stirring, then mix the weight proportion 1:1.5 of biological complex enzyme biochemical agent and crushed straw aggregate with above-mentioned standby crushed straw aggregate;
C, pack above-mentioned and the mixed crushed straw aggregate of biological complex enzyme biochemical agent in biochemical container boxcar anaerobic fermentation, between 25 ℃～45 ℃, allow stalk spontaneous fermentation 48 hours under the catalysis of biological complex enzyme biochemical agent;
D, above-mentioned tunning is sent into paper pulp manufacturing technique flow process, through feeding machine, dense grinding machine, enter Chi Tiaonong, wash Gu, jump sieve, belt type dewaterer, enter Chi Tiaonong, desanding, pressurized screen, mill, pull an oar, discongest, pressurized screen, circulating tank, papermaking operation.
Principle of the present invention is: in stalk native cellulose material, contain a considerable amount of heterocycle polymers, as pectin, silica, lignin etc., its degree of crystallinity and the degree of polymerization are very high, and in stalk except containing cellulose 30-50%, hemicellulose accounts for 10-15%, lignin accounts for 15-20%, its structure is very tight, cellulosic skin is hemicellulose, the skin of hemicellulose is lignin, only have lignin destroyed, hemicellulose and cellulose just can be decomposed softening, then transform the required paper pulp of copy paper after entering wash-out, purification, fine grinding.Biological complex enzyme biochemical agent of the present invention carries out fermentation process to stalk, stalk cellulose, hemicellulose and lignin are decomposed, and make lignin and cellulose, hemicellulose separated, cause cell wall expansion, make cell cellulose structure lose rockiness, the pine that becomes is dredged soft.For stalk cellulose, hemicellulose and cell membrane thereof are destroyed, decomposed and transform, add in right amount cellulase, hemicellulase very necessary.Straw biological paper pulp is typical enzyme reaction, is a part for enzyme engineering.
The alkaline slaking of synchronous use is chemical activator and bioactivator combination, strengthen enzyme group biologically active, make the subsidiary nature multiple beneficial bacterium of stalk self, as normal growth breedings such as lactic acid bacterias, and stalk is synchronously discongested, the cellulose degradation of stalk is reached to the desired softening grog of biological paper pulp.
Effect of the present invention shows: 1. cleaning pulping.Adopt biofermentation technique, substituted traditional high temperature, the pulping process of autoclaving; Without complicated technological process, in whole pulping process, do not produce black liquor, rear reuse is filtered in pulp washing water sedimentation, and not blowdown, not draining, using water wisely, really solved pollution-free cleaning pulping.2. reduce costs.Tradition papermaking main raw material(s) is timber, with agricultural crop straw, substitutes timber, turns waste into wealth, and can significantly reduce costs, and protection is ecological again, development agriculture-countryside-farmer economy.
Accompanying drawing explanation
Fig. 1 is paper pulp manufacturing technique schematic flow sheet of the present invention.
The specific embodiment
A biochemical agent, by take weight percentage with following raw materials according, as unit, enumerate 3 real row and mix and form:
Biological complex enzyme biochemical agent, for a preparation method for straw biological paper pulp, comprises the following steps:
A, first by Mechanical Method, Straw Kneading is broken, is refined to 1.5-2 millimeters, makes crushed straw aggregate, standby;
B, biological complex enzyme biochemical agent is carried out to premix in ratio separately, then with 50 times of water purification mixing and stirring, then mix the weight proportion 1:1.5 of biological complex enzyme biochemical agent and crushed straw aggregate with above-mentioned standby crushed straw aggregate;
C, pack above-mentioned and the mixed crushed straw aggregate of biological complex enzyme biochemical agent in biochemical container boxcar anaerobic fermentation, between 25 ℃～45 ℃, allow stalk spontaneous fermentation 48 hours under the catalysis of biological complex enzyme biochemical agent;
D, above-mentioned fermentate is sent into paper pulp manufacturing technique flow process, through feeding machine, dense grinding machine, enter Chi Tiaonong, wash Gu, jump sieve, belt type dewaterer, enter Chi Tiaonong, desanding, pressurized screen, mill, pull an oar, discongest, pressurized screen, circulating tank, papermaking operation.Detailed pulping process flow as shown in Figure 1.
