Problems solved by technology

It was found that the difference between the temperature of the upper space of the oven and the temperature of the lower space was more than 10°C, which caused the material to be heated unevenly; and the metal baking pan was placed directly on the heating pipe, and the actual temperature of the material at the bottom was much higher than the temperature of the oven. The temperature value measured by the table shows that the heat transfer between metal and metal is fast, the temperature of the material at the bottom is higher than the surface temperature of the material, and the surface of the material is heated unevenly, resulting in uneven quality of the dry paste

Embodiment 1

[0031] (1) Ingredients: The dosage of the drug raw materials is as follows in parts by weight:

[0032] Take 4 parts of white peony; 3 parts of tangerine peel; 2 parts of Polygonum multiflorum; 2 parts of medlar; 1 part of licorice.

[0033] Process Polygonum multiflorum and licorice, add Polygonum multiflorum to black bean juice to steam, and roast licorice honey.

[0034] (2) Extract the extract:

[0035] Boil white peony root, tangerine peel, Polygonum multiflorum multiflorum multiflorum, Radix Glycyrrhizae and Lycium barbarum for three times. The amount of water added for the first time is 8 times the amount of the medicinal materials, the second time is 4 times the amount of the medicinal materials, and the third time is the amount of the medicinal materials. 4 times, soak the medicinal materials for 30 minutes before the first decoction, boil and reflux for 1 hour each time, filter, combine the filtrate three times, and concentrate under vacuum at 60°C to a clear paste ...

Abstract

The invention discloses a method for preparing extracted extractum for preparing drugs for treating biliary tract infection, comprising the following steps of: spreading the blended and extracted extractum into a baking pan according to 3-5 Kg/pan; setting the material temperature of a microwave vacuum drying sterilizer to 60-70 DEG C and operating time to 60-100 minutes, and drying to obtain dry extractum under the condition that vacuum degree is controlled between -0.08 MPa and -0.09 MPa; and crushing the dry extractum to surpass 100 meshes so as to obtain dry extractum powder. The invention adopts a microwave vacuum drying method, has the advantages of fast drying, high energy utilization ratio, good drying and sterilizing effect, high finished product quality, controllable production, high automation degree and good production environment, meets the requirements of GMP (Good Manufacturing Practice) and also greatly reduces the production cost.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, in particular to a method for drying extracts of medicines for treating biliary tract infection. Background technique [0002] In the production of modern traditional Chinese medicine, one of the most difficult problems for pharmaceutical companies is the drying of the extract. At present, pharmaceutical companies mainly use traditional oven vacuum drying or spray drying to dry extracts. These traditional drying methods have high drying temperature, high energy consumption, large equipment investment, long production cycle, low benefit, high cost, and land occupation. Issues such as large area. Therefore, extract drying has become a "bottleneck" in the production of pharmaceutical companies, limiting the development of production. [0003] In the prior art, the medicinal extract for treating biliary tract infection is dried in an oven. It was found that the difference bet...
