Wet granulation production process using high-speed rotary wet granulation and fluidized bed drying machine equipment combined into granulation production line, present in many domestic pharmaceutical companies have been widely used. Domestic equipment selection based on the principles of: energy saving and environmental protection. We have proposed a series of equipment requirements, including with suppliers to explore the technical feasibility in equipment selection. Here, we fluidized bed URS standards required by provisions of the US FDA to discuss several topics as a reference. Changzhou Heng Cheng Fusite Drying Equipment Co., Ltd. mainly produces: drying, granulation, mixing, grinding, dust, and other products, niche products: flash dryer, a vacuum dryer, spray dryer, vibration fluidized bed dryer, air dryers, belt dryers, strengthen fluidized bed dryer, paddle dryer, tray dryer and the like. The fluidized bed has that kind of performance as the liquid flow, solid particles ejected from the container wall of the hole. And as liquid as the inflow from a container to another container; Again, smaller than a bed density of the object can be easily pushed into the bed, and a release, it pops up and floats on the surface of the bed; when When the container is tilted, general-purpose fluidized bed dryer, the upper surface of the bed to keep the level of connectivity as the two beds, their own bed adjusted to the same level; any pressure changes between the two sections of the bed approximately equal gravity between the two cross-sectional area of ??the bed unit.
