Abstract

The invention belongs to the technical field of biomedicine, in particular relates to an anhydrous dextrose drying device and a drying process. The technical scheme is that the anhydrous dextrose drying device comprises a fluidized bed and a back mixing bed. The fluidized bed comprises a first-section fluidized bed and a second-section fluidized bed. The lower portion of the back mixing bed is connected with an air inlet pipe I through an air feeder I, a heater I is arranged on the air inlet pipe I, an air inlet pipe II and an air inlet pipe III are respectively connected with the first-section fluidized bed, an air inlet pipe IV and an air inlet pipe V are respectively connected with the second-section fluidized bed, an air feeder II is respectively connected with the air inlet pipe II, the air inlet pipe III, the air inlet pipe IV and the air inlet pipe V through a heat exchanger II, so that the phenomena that finished products are apt to change colors and blocked caused by high temperature of materials caused by continuous drying can be avoided.

Description

technical field

[0001] The invention belongs to the technical field of biomedicine, and in particular relates to anhydrous glucose drying equipment and a drying process. Background technique

[0002] Glucose is an indispensable nutrient for the metabolism of organisms. The heat released by its oxidation reaction is an important source of energy for human life activities. It can be used directly in the food and pharmaceutical industries. In the industry, a large amount of glucose is used as a raw material to synthesize vitamins. c. Its main preparation products are large infusion solution and hyperosmotic medium needle. Due to the special administration route of infusion solution and medium needle, the quality of raw materials is particularly important. Especially heat source reaction, impurity content, foreign matter, etc., if not guaranteed, may cause great harm to patients. Dextrose anhydrous is a replacement product for the production of infusions or middle needles. Cou...
