Raw sugar loss late is 48.54%, and the removal rate of furfural reaches 74.91%, and phenolic compound can be removed all, again passes by baking
Dry step dries wheat-straw；
It crushes: after the wheat-straw of drying is air-cooled, putting into pulverizer, cross 80~100 mesh when wheat-straw exports after crushing
Sieve, unsifted stalk foam grind and crossed 16~20 meshes again；
Macromolecule mixing: the stalk foam of sieving, calcium carbonate, dioctyl sebacate, reactive assistant, resists aldehyde crosslinking agent
Oxygen agent, lubricant, ultraviolet absorbing agent, light stabilizer, water and microbial deodorant mixing are 80~90 DEG C in temperature, and lead to
It crosses High-efficient Stirrer and stirs 20~30min, reach mixed uniformly purpose, degradable thick mixture is transferred to spiral
In formula cooler, it is stirred cooling；
Granulation: degradable granular materials is squeezed out by twin-screw extrusion granulator；
Blown film: high speed inflation film manufacturing machine is used, degradable granular materials is blow molded into the full degradable mulch of controllable biological base.
As a preferred technical solution of the present invention, the biomass fiber 200--1500 mesh micro mist of the mulch can be
One of wheat-straw, stalk, rice straw, animal hair etc. or several mixture.
As a preferred technical solution of the present invention, the exhaust gas generated in the baking step, extremely by pipeline
The input terminal of stalk dryer, preheats wheat-straw, final exhaust gas by purify it is up to standard after, be discharged into atmosphere.
As a preferred technical solution of the present invention, the ultraviolet absorbing agent selects UVP-327.
As a preferred technical solution of the present invention, the degradable granular materials in the granulation step is irregular
Shape.
As a preferred technical solution of the present invention, the mulch in the blown film step is wound using winder, packaging,
Storage.
Compared with prior art, the beneficial effects of the present invention are: a kind of addition biomass fiber controllable biological base of the present invention
Full degradable mulch, by the way that biomass fiber is added, biomass fiber 200--1500 mesh micro mist includes wheat-straw, stalk, rice
One of bar, animal hair etc. or several mixture make full use of resource, and more environmentally friendly, the mulch produced is degradable, raw
Production method is simple, at low cost, has the application prospect being widely popularized to promotion China's soil pollution treatment, the aspect that develops eco-agriculture.
