Embodiment 1
[0014] Take 1000g of pharmaceutical waste residue and dry it for 3 hours under the condition of vacuum degree of 3000Pa and microwave power of 267W until the water content of the dry waste residue is 10%.
[0015] Get 50g of pharmaceutical waste residue with a water content of 10% as a substrate, add 295ml of tap water to make the pharmaceutical waste residue substrate concentration 15%, then stir evenly, adjust the pH to 7.0 with sodium hydroxide solution, heat up to 50°C and add papain (the activity is 300,000 units) and neutral protease (the activity is 50,000 units) to make 5g of compound enzyme by weight ratio of 1:5, keep it warm for 8 hours, then raise the temperature to 70°C, keep it warm for 15 minutes to kill the enzyme , the enzymatic hydrolysis rate reaches 70%. After the enzyme is eliminated, the enzymatic hydrolysis solution is separated from the residue. The enzymatic hydrolysis solution produces polypeptide and amino acid products, and the enzyme residue is dri...
Embodiment 2
[0017] Take 1000g of pharmaceutical waste residue and dry it for 7 hours under the condition of vacuum degree of 2500Pa and microwave power of 160W until the water content of the dry waste residue is 12%.
[0018] Get 100g water content and be the pharmaceutical waste residue of 12%, add tap water 721ml to make the waste residue substrate concentration be 12%, stir then, pH is adjusted to 7.2 with sodium hydroxide solution, be warming up to 52 ℃ and add by papain (activity is 30 10,000 units) and neutral protease (the activity is 50,000 units) are made into 7.7g of compound enzyme by 1:5 weight ratio, keep warm for 6 hours, then raise the temperature to 72 ℃, keep warm for 12 minutes to kill the enzyme, the enzymolysis rate After reaching 65%, the enzymatic hydrolysis solution is separated from the residue after the end of the enzyme inactivation. The enzymatic hydrolysis solution produces polypeptide and amino acid products, and the enzyme residue is dried as flower nutrient ...
Embodiment 3
[0020] Take 1000g of pharmaceutical waste residue and dry it for 5 hours under the condition of vacuum degree of 2000Pa and microwave power of 350W until the water content of the dry waste residue is 8%.
[0021] Get 50g water content and be 8% pharmaceutical waste residue, add tap water 452ml and make substrate concentration be 10%, stir then, pH is adjusted to 7.5 with sodium hydroxide solution, be warming up to 55 ℃, add by papain (activity is 30 10,000 units) and neutral protease (activity is 50,000 units) compound enzyme 3g that is made into through 1:5 weight ratio, keep warm for 10 hours, then raise the temperature to 75 ℃, keep warm for 10 minutes to kill enzyme, enzymolysis rate After reaching 60%, the enzymatic hydrolysis solution is separated from the residue after the enzyme inactivation is completed. The enzymatic hydrolysis solution produces polypeptide and amino acid products, and the enzyme residue is dried as flower nutrient soil.
