Information

Drying can be divided into two categories, one requires that after drying, raw materials remain the original shape, such as many kinds of food drying, building materials drying, etc. The other is to dry liquid, muddy, massive and powdery materials into powdery or granular products, Some drying processes, especially the drying of drugs, hope not to destroy the original crystal shape. In pharmaceutical production, liquid and powder materials are often used to reach a certain size of particles after drying. There are also technical problems in the feeding and discharging of dryers, and many aspects still need to rely on practical experience. From the economic point of view, the size of the treatment capacity is also one of the factors to choose the type of drying equipment. Table 1-7 summarizes the selection of dryers based on materials. Table 1-7 selection of raw materials according to materials, suitable initial drying conditions, suitable drying machines for large batch continuous treatment, small amount of treatment liquid, slurry spray drying, fluidized bed multi-stage drying, drum type, vacuum belt inert medium fluidized bed paste flow drying, stirring rotary drying, ventilation belt drying, impact wave spray drying, conduction heating cylinder stirring. Drying Conduction Heating Tank Stirring Drying Ventilation Box Type Drying Flake Type Belt Ventilation Drying Rotary Snake Tube Through Steam Drying Rotary Ventilation Drying Box Type Ventilation Drying Vacuum Cylinder Type Stirring Granular Material Belt Ventilation Drying, Rotary Ventilation Drying Vertical Ventilation Drying Fluidized Bed Drying Rotary Steam Snake Tube fluidized bed tank type mixing box type ventilation drying conical rotary dryer multi-layer disc drying powder material fluidized bed drying airflow drying intermittent fluidized bed drying vacuum cylinder type with stirring shaped material advection tunnel type advection trolley type box type sheet type, multi-cylinder type single or multi-cylinder type coating, coating liquid infrared ray, Following is the general scope of application of various types of dryers. The detailed application of each type of dryer will be further introduced in the following content.
