Its main raw material of wood fibre is crop material, after handling accordingly, acquisition pulvis raw material, and due to
Different makees raw material, and the end properties after its actual processing are different, and peanut shell contains crude protein, cellulose, fat due to it
And multivitamin, when thus be accordingly used in lignocellulosic processing, it is possible to achieve the stronger performance of cellulose, and due to wooden at present
Cellulose processing technology is relatively single, and using peanut shell in the processing of reality, the processing of not relative science, therefore
Lignocellulosic processing is carried out using peanut shell, can not be popularized, be caused peanut shell to prepare lignocellulosic and technology bottle occur
Neck.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of processing technology is simple, and processing method is scientific and reasonable, system
The superior method that lignocellulosic is prepared based on peanut shell of standby end properties.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of method that lignocellulosic is prepared based on peanut shell, it is characterised in that comprise the steps：
1) market purchase obtains direct field and collects the peanut shell for removing fruit, removes the rotten composition that wherein goes mouldy, so
Unify collection afterwards and carry out tiling airing；
2) when the actual moisture content of peanut shell is 10-12% after above-mentioned airing, its all raw material is all put into freezer
In, low temperature precooling is carried out, it is 2-3 DEG C to control temperature, is stood after preserving 20-25min, then is cooled 0-1 DEG C, preserves 10-15min,
- 12 DEG C are finally cooled to, is ensured, after standing 5-8min, is taken out until reaching room temperature；
3) peanut shell after above-mentioned taking-up is all put into clear water reserviors, after soaking 20-30min, taking-up drains away the water, entirely
Portion is thrown in alkali lye pond, is carried out alkali bubble 20-25min, is taken out and cleaned 3-5 times using clear water；
Alkali lye in described alkali lye pond is prepared using the raw material of following parts by weight：It is sodium hydroxide 30-35 parts, small
Soda 10-15 parts, white lime 2-4 parts, vermiculite power 3-4 parts, nicotine 2-4 parts, deionized water 35-45 parts；
4) peanut shell after above-mentioned steps 3 are handled carries out drying and processing, until after moisture content is 3-5%, carries out preliminary
It is broken, obtain coarse powder；
5) by above-mentioned coarse powder and frozen water according to 1:2 amount is integrally thrown in grinder, opens grinding, until coarse powder is ground
After uniformly, the modified starch for adding total amount 1/10 is stirred compounding；
6) material in above-mentioned steps 5 is integrally poured out, is then filtered using the screen of 500 mesh, finely filtered
Liquid；
7) fine filtrate is thrown to be concentrated under reduced pressure in tank and concentrated, until relative density 1 ± 0.01, after concentration
Liquid obtains finished product by spray drying technology.
In the present invention, after carrying out corresponding sorting cleaning as major ingredient using peanut shell, step-by-step freezing is being carried out, it is ensured that
Crude protein, cellulose, fat in peanut shell are stored, after then being steeped by alkali, it is ensured that the clean performance of raw material, simultaneously
The toughness of internal fiber raw material is realized, after water mill, after acquisition water mill liquid is concentrated under reduced pressure accordingly, spray drying
Obtain.
Beneficial effects of the present invention are：Processing technology of the present invention is simple, scientific and normal, using peanut shell as raw material
When using, the cheap performance of the raw material of guarantee, while processing, clean pollution-free, the lignocellulosic performance obtained after preparation is more
Add superior.
