Embodiment 1

[0034] The method for preparing bio-fertilizers of the present embodiment utilizing fat, saponin and protein class traditional Chinese medicine dregs wastes comprises the following steps:

[0035] Step 1. Centrifugal dehydration:

[0036] The traditional Chinese medicine dregs are successively washed with water and centrifuged to dehydrate, and the centrifuge speed is controlled to be 4000rmp to obtain a centrate, which is set aside.

[0037]Step 2, constant temperature and low pressure hydrolysis:

[0038] Add dilute sulfuric acid solution with a mass concentration of 20% to the centrifuged traditional Chinese medicine residue as a catalyst, and perform constant temperature and low pressure hydrolysis in a hydrolysis tank with a controlled pressure of 0.13 MPa, a constant temperature of 90°C, and a hydrolysis time of 8 hours.

[0039] Step three, enzymatic hydrolysis:

[0040] Add a compound enzyme preparation to the hydrolyzed material (residue) after hydrolysis, and carry...

Embodiment 2

[0047] Step 1. Centrifugal dehydration:

[0048] The traditional Chinese medicine dregs are successively washed with water and centrifugally dehydrated, and the centrifugal speed is controlled to be 3800rmp to obtain a centrate, which is set aside.

[0049] Step 2, constant temperature and low pressure hydrolysis:

[0050] Add dilute sulfuric acid solution with a mass concentration of 18% as a catalyst to the centrifuged traditional Chinese medicine residue, and carry out constant temperature and low pressure hydrolysis in the hydrolysis tank, the control pressure is 0.1MPa, the constant temperature is 85°C (90°C), and the hydrolysis time is 8.5h .

[0051] Step three, enzymatic hydrolysis:

[0052] Add a compound enzyme preparation to the hydrolyzed material (residue) after hydrolysis, and carry out enzymatic hydrolysis at 45°C; the compound enzyme preparation includes alkaline protease, lipase, amylase, pectinase, hemicellulase and cellulose Enzyme, the total dosage of co...

Embodiment 3

[0059] Step 1. Centrifugal dehydration:

[0060] The traditional Chinese medicine dregs are sequentially washed with water and centrifugally dehydrated, and the centrifugal speed is controlled to be 4200rmp to obtain a centrate, which is set aside.

[0061] Step 2, constant temperature and low pressure hydrolysis:

[0062] Add dilute sulfuric acid solution with a mass concentration of 22% to the centrifuged traditional Chinese medicine residue as a catalyst, and carry out constant temperature and low pressure hydrolysis in a hydrolysis tank with a controlled pressure of 0.15 MPa, a constant temperature of 95°C, and a hydrolysis time of 7.5 hours.

[0063] Step three, enzymatic hydrolysis:

[0064] Add a compound enzyme preparation to the hydrolyzed material (residue) after hydrolysis, and carry out enzymolysis at 55°C; the compound enzyme preparation includes alkaline protease, lipase, amylase, pectinase, hemicellulase and fiber Sulfase, the dosage of compound enzyme prepara...

Abstract

The invention relates to the technical field of resource utilization of traditional Chinese medicine residues, in particular to a method for preparing a biological fertilizer by utilizing traditionalChinese medicine residue waste containing fat, saponins and proteins; the method comprises the steps of rinsing, centrifugal dewatering, constant-temperature low-pressure hydrolysis, enzymolysis, fermentation and the like. The method solves the problems of long period, incomplete fermentation and secondary pollution of the fertilizer prepared from the traditional Chinese medicine residues at present, the biological fertilizer prepared by the method plays a role in both pesticide and fertilizer, and the traditional Chinese medicine residues of plants are truly absorbed and utilized completely.

Description

technical field [0001] The invention relates to the technical field of resource utilization of traditional Chinese medicine dregs, in particular to a method for preparing biological fertilizers from wastes of traditional Chinese medicine dregs containing fat, saponin and protein. Background technique [0002] Extraction of plant traditional Chinese medicine preparations is the core part of traditional Chinese medicine, and the industrial extraction of traditional Chinese medicine preparations is particularly important. my country's traditional Chinese medicine extraction industry has a large scale. Chinese medicine dregs are solid wastes produced in the process of making traditional Chinese medicines. The annual output is as high as several million tons. Classified substances, if a large amount of traditional Chinese medicine dregs are discarded without treatment, especially in high-temperature and humid places, it is easy to become rancid and deteriorate, seriously affecting...
