|Application of boiling range of dryer in the pharmaceutical industry
Boiling drier can be widely used in the production of the API, application of varieties are: amoxicillin, ampicillin, ARCOR aspirin, dibydro streptomycin, kanamycin, ampicillin, penicillin, tetracycline, streptomycin, chloramphenicol succinate fog, sulfathiazole, vitamin A, vitamin E, vitamin B12, hydrogen chloride, sulfate aluminum Shu glycolipid, amylase, barium sulfate, calcium lactate, calcium pantothenate, hormones, L-lysine, nicotinic acid, protease, rutin derivatives, liver extract etc..
With the continuous development of applied technology, boiling type and application of dryer is also increasing, classification method of equipment are also different. According to the materials to be dried can be divided into three categories: the first category is granular material; the second category is the paste materials; the third category is the suspension and solution with mobility material. According to the operating conditions, basically can be divided into two categories: continuous and intermittent. According to the structure of state to general fluidization type, mixed flow type, vibration. Boiling drying of material adaptability is better because, it compared with hot air circulation oven, covers an area of small, large production capacity, high thermal efficiency, and the dried product moisture uniformity. Compared with air drying, can be adjusted by the residence time of material in the fluidized bed length, so that products meet the expected rate of water.
The dryer is introduced from the above three aspects of boiling the drying equipment factory. From the operating conditions: GFG series efficient boiling dryer, FG series boiling dryer is intermittent, materials to be dried particles have certain requirements, general requirements of not less than 30 micron, not more than 4mm for the right. When several materials mixed together when dry, all kinds of material ratio should be close to. XF series high boiling drier, ZLG series vibrating fluidized bed dryer is continuous, and can meet the requirements of continuous production.
