Example Embodiment
[0030] Example 1:
[0031] The specific preparation process of quaternized crab shell is as follows:
[0032] Step 1: Take 10kg of crab shells, wash them, dry and grind them, add 100L of hydrochloric acid solution with a concentration of 5mol / L to soak for 12 hours, and keep stirring during the soaking process to make the calcium in the crab shells Dissolve, then filter, wash and dry to obtain pretreated crab shells;
[0033] Step 2: Add the pretreated crab shells obtained in step 1 to a sodium hydroxide solution with a concentration of 40%, heat up to 50°C for a deacetylation reaction for 6 hours, and then perform filtration, washing and drying to obtain chitosan;
[0034] Step 3: Add the chitosan prepared in step 2 to a 5% acetic acid solution to prepare a chitosan solution with a concentration of 0.05g / mL, and then add 2,3-ring to the 100L chitosan solution Oxypropyltrimethylammonium chloride, stirred and reacted at 50℃ for 7h, filtered, washed and dried to obtain quaternary ammon...

[0035] Example 2:
[0036] A preparation method of green and pollution-free pig feed, the specific preparation process is as follows:
[0037] In the first step, 59kg of bagasse, 37kg of soybean meal, 45kg of wheat bran, 38kg of alfalfa and 27kg of distiller’s grains are dried and crushed to a particle size of less than 1cm;
[0038] In the second step, add edible vinegar to water to prepare a solution with pH=5.8-6, then add 2.3kg cellulase and 1.2kg xylanase to it, and crush the bagasse, wheat bran, Alfalfa and distiller's grains are added to the solution, heated to 55°C and stirred at low speed for 72 hours, then filtered, the filter residue is dried for use, and the filtrate is retained for use;
[0039] In the third step, add 34kg of cornmeal and the residue from the first step of filtration into the water, adjust the pH=8.2-8.5, and add 4.2kg of alkaline protease to it, raise the temperature to 50℃ and stir at low temperature for 3 days, then filter the cornmeal and the first st...

[0042] Example 3:
[0043] A preparation method of green and pollution-free pig feed, the specific preparation process is as follows:
[0044] In the first step, 63kg of bagasse, 41kg of soybean meal, 51kg of wheat bran, 42kg of alfalfa and 29kg of distiller’s grains were dried and crushed to a particle size of less than 1cm;
[0045] In the second step, add edible vinegar to water to prepare a solution with pH=5.8-6, then add 2.8kg cellulase and 1.4kg xylanase to it, and crush the bagasse, wheat bran, Alfalfa and distiller's grains are added to the solution, heated to 55°C and stirred at low speed for 72 hours, then filtered, the filter residue is dried for use, and the filtrate is retained for use;
[0046] In the third step, add 38kg of cornmeal and the residue from the first step of filtration into water, adjust the pH=8.2-8.5, add 4.5kg of alkaline protease to it, heat up to 50℃ and stir at low temperature for 3 days, then filter the cornmeal and the first step The remaining res...
