Embodiment 1
[0025] (1): Pulping
[0026] Cut the wheat straw to a length of about 5cm and wash the preparation material with water, put the prepared material into the steam ball, add lye, steam into the steam ball, wheat straw in 140 ° C saturated vapor to do alkali cooking for 30min, pressure relief and cooling to remove the material, with 5% pulp into the disk grinding and grinding, to obtain wheat grass pulp.
[0027] (2): Screening
[0028]The pre-treated wheat grass pulp is mixed into 3% pulp concentration, put into the overclocking vibrating screen mesh, the number of screen mesh is 50 mesh, the frequency is 20000HZ, the low crystalline fiber solution through the screen is collected, placed aside to make the fiber settle for 30min, the upper layer clear liquid is extracted, and the low crystalline fiber solution at the bottom is separated from the solid liquid to obtain the low crystalline fiber solid material.
[0029] (3): Enzymatic lysis
