Abstract
The invention discloses a kind of biological complex enzyme biochemical agent and the preparation method for straw biological paper pulp thereof, biological complex enzyme biochemical agent by corn flour 50～60, molasses 2～8, yeast 15～25, cellulase 10～20, carbohydrase 10～20 by weight percentage composition mix form. Biological complex enzyme biochemical agent, for the preparation method of straw biological paper pulp, comprises the steps such as Straw Kneading is broken, biological complex enzyme biochemical agent mixes with water, crushed straw aggregate, fermentation, pulp production. Effect of the present invention shows that cleaning pulping and production cost reduce, and with the alternative timber of agricultural crop straw, turns waste into wealth, and protection is ecological.
Description
Technical field
The present invention relates to a kind of biological complex enzyme biochemical agent and the method for the preparation of straw biological paper pulp thereof.
Background technology
The agricultural straw resource of China is very abundant, produces every year more than 5.7 hundred million tons, shows China according to interrelated dataAnnual waste stalk is more than approximately 2.5 hundred million tons. But, as these resources are turned waste into wealth, produce for biological paper pulp, replace traditionTimber papermaking, reduces papermaking cost, and tool is of great significance. In addition, traditional paper technology is high temperature, high-alkali, highPress boiling method, belong to high pollution industry.
Summary of the invention
Thereby the object of the invention is to adopt in order to overcome existing issue biofermentation technique to provide a kind of biological compoundEnzyme biochemical agent and for the preparation method of straw biological paper pulp.
For achieving the above object, the technical scheme providing is:
A kind of biological complex enzyme biochemical agent, by following raw materials according by weight percentage composition mix and 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, for subsequent use;
B, biological complex enzyme biochemical agent is carried out to premix in ratio separately, then with 50 times of water purification mixing and stirring, soMix afterwards the weight proportion 1:1.5 of biological complex enzyme biochemical agent and crushed straw aggregate with above-mentioned crushed straw aggregate for subsequent use;
C, pack above-mentioned and the mixed crushed straw aggregate of biological complex enzyme biochemical agent in biochemical container boxcar anaerobic fermentation,Between 25 DEG C～45 DEG C, 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, washAncient, jump sieve, belt type dewaterer, enter Chi Tiaonong, desanding, pressurized screen, mill, pull an oar, discongest, pressurized screen, circulating tank, paper makerOrder.
Principle of the present invention is: in stalk native cellulose material, contain a considerable amount of heterocycle polymers, as pectin, twoSilica, lignin etc., its degree of crystallinity and the degree of polymerization are very high, and in stalk except containing cellulose 30-50%, hemicellulose accounts for10-15%, lignin accounts for 15-20%, and its structure is very tight, and cellulosic skin is hemicellulose, the skin of hemicelluloseBe lignin, only have lignin destroyed, hemicellulose and cellulose just can be decomposed softening, then enter wash-out, purification, fine grindingThe required paper pulp of rear conversion copy paper. Biological complex enzyme biochemical agent of the present invention carries out fermentation process to stalk, by stalk cellulose,Hemicellulose and lignin decompose, and lignin is separated with cellulose, hemicellulose, cause cell wall expansion, make cell fibreTie up plain structure and lose rockiness, become pine and dredge soft. For stalk cellulose, hemicellulose and cell membrane thereof being destroyed, dividingSeparate and transform, add in right amount cellulase, hemicellulase very necessary. Straw biological paper pulp is typical enzyme reaction, is enzymeA part for engineering.
The alkaline slaking of synchronous use is chemical activator and bioactivator combination, strengthens enzyme group biologically active, makes stalkThe nature multiple beneficial bacterium that self is subsidiary, as normal growth breedings such as lactic acid bacterias, and synchronously discongests stalk, by strawThe cellulose degradation of stalk reaches the desired softening grog of biological paper pulp.
Effect of the present invention shows: 1. cleaning pulping. Adopt biofermentation technique, substituted traditional high temperature, high pressureThe pulping process of boiling; Without complicated technological process, in whole pulping process, do not produce black liquor, after pulp washing water sedimentation is filteredReuse, not blowdown, not draining, using water wisely, really solved pollution-free cleaning pulping. 2. reduce costs. Tradition papermaking is mainRaw material are timber, with the alternative timber of agricultural crop straw, turn waste into wealth, and can significantly reduce costs, and protection is ecological again, development threeAgriculture economy.
