Embodiment 1

[0024] (1) Dissolution of crude lactose: Dissolve crude lactose in a pot, add 0.5% activated carbon under mechanical stirring, heat and boil for 30 minutes, so as to ensure that impurities are removed and obtain a concentration of 30-32 ° Be ' A mixture of crude lactose and activated carbon;

[0025] (2) Pressure filtration: transfer the mixed solution of crude lactose and activated carbon prepared in step (1) to a 400-mesh thermal insulation laminated plate-and-frame filter while it is hot, and use it to filter out activated carbon and impurities adsorbed by activated carbon. And pigment, filtering while it is hot can avoid lactose precipitation and reduce the amount of later operations. Using a 400-mesh thermal insulation laminated plate and frame filter can ensure that there is no activated carbon in the filtrate and ensure that the filtrate is pure;

[0026] (3) Crystallization: transfer the pure lactose solution prepared in step (2) into a crystallization tank for cooling...

Embodiment 4

[0041] Embodiment 4 is the best implementation mode.

[0042]The above test results show that the technical solution of the present invention is scientific and reasonable, and the obtained medicinal lactose complies with the provisions of the 2010 edition of the Chinese Pharmacopoeia. In actual production, the production process parameters of medicinal lactose and the operation of the crushing and drying machine can be adjusted according to production requirements. parameters, so that the production cost can be minimized and the maximum benefit can be obtained.

Abstract

The invention belongs to the field of medicine and particularly relates to an officinal lactose production technology which comprises the following steps: dissolution, filter pressing and crystallization of coarse officinal lactose, and desorption, washing, drying and smashing of a mother liquor; production equipment for realizing the production technology of the officinal lactose comprises a feeding device, a smashing device, a grading device, an induced draft fan, a hot blast heater and a cyclone separator, wherein the smashing device comprises a smashing cavity and a smashing shaft; a smashing disc is connected with the smashing shaft; the smashing shaft is connected with an electric motor. The officinal lactose production technology, disclosed by the invention, has the following benefits: during the production process of the officinal lactose, the steps of drying and smashing are completed at one step by adopting a smashing and drying machine, so that the labor cost is greatly reduced, and time and labor are saved; in addition, a radial hot-blast air intaking mode is adopted by the smashing and drying machine, and smashing and drying are carried out simultaneously, so that residual moisture in the lactose is removed easily, and the officinal lactose has high yield and purity. The production technology is advanced, and the quality of the officinal lactose reaches the world standard.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a production process of medicinal lactose. Background technique [0002] Lactose is a unique disaccharide in mammalian milk. Lactose is composed of a molecule of glucose and a molecule of galactose, and is a common disaccharide in mammalian milk. Lactose is one of the main nutrients for children's growth and development. It is very important for the intellectual development of adolescents, especially for newborn babies. It is often used in the manufacture of baby food, candy, and artificial milk. The lactose content in bovine milk is 4.6-4.7%, and the lactose content in human milk is 6-8%. Lactose is 1 / 5 as sweet as sucrose. In the food industry, lactose is used as baby food and condensed milk varieties. In the pharmaceutical industry, it is used as a flavoring agent, excipient, diluent, filler, dry powder inhalation carrier, stabilizer, etc. of medicines; in addition, it c...
