The basic principle of boiling drying

Definition of Boiling Drying: Boiling drying, also known as fluidized drying, refers to the process of drying solid particles in a fluidized state using a drying medium.

Boiling dryerPrinciple: It refers to the drying of solid particles in a fluidized state by a drying medium. The basis of the material drying process is the boiling of the powder. At the same time, under the action of exhaust, the fine powder in the container is filtered by a capture bag and discharged to the outside. During drying, due to the counter current contact between gas-solid phases, there is intense agitation. Solid particles suspended in a drying medium have a large contact surface area and are excellent in terms of heat and mass transfer, volumetric drying strength, thermal efficiency, and other aspects.

Due to its good adaptability to various materials, boiling drying has a smaller footprint, larger production capacity, higher thermal efficiency, easier operation control, and less particle damage compared to other drying machines. It is currently widely used, especially in the pharmaceutical industry.

Boiling dryerCharacteristics of

Due to the large contact area between the material and the drying medium, as well as the continuous vigorous agitation of the material in the bed, the heat transfer effect is good and the heat capacity coefficient is large;

Due to the uniform temperature distribution inside the fluidized bed, any local overheating of the product is avoided, making it particularly suitable for drying certain thermosensitive materials;

Continuous or intermittent operations can be performed within the same device;

The residence time of materials in the dryer can be adjusted as needed, so the moisture content of the product is stable;

The drying device itself does not include mechanical moving parts, so the investment cost of the equipment is low and the maintenance workload is relatively small.

Application scope of boiling drying in the pharmaceutical industry

Boiling drying can be widely used in the production of raw materials, including amoxicillin, ampicillin, ampicillin, kanamycin, ampicillin, penicillin, tetracycline, streptomycin, chloramphenicol, sulfathiazole, vitamin A, vitamin E, vitamin B12, aluminum oxychloride, aluminum sulfate glycolipids, amylase, barium sulfate, calcium lactate, calcium pantothenate, hormones, L-lysine, niacin, protease, rutin derivatives, liver essence, etc.
