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, fluid bed dryers, belt dryers, paddle dryers, disc dryers and the like. Fluidized bed drying technology development process is a fluidized dryer easiest single-cylinder type, the disadvantage of this dryer is widely distributed in residence time in the fluidized bed, the resulting dried product moisture content is uneven, the diameter should not be too Big. To improve this situation, the development of a multi-layered fluid bed dryer. A multistage operation improves efficiency, durability fluidized bed dryer, but more importantly, it can be more desirable solid particles residence time distribution, and greatly narrows the residence time distribution, the material to avoid short-circuiting during the drying process. Start is the use of the overflow pipe and downstream pipe, subsequent development into a multi-layered fluid bed through flow plate. Drying is mainly used for diffusion control of materials, such as polyester resin, grains, quartz sand, polypropylene particles. But it has the operation more difficult, the sieve material layer is not easy to build, large bed resistance, complex structure and other shortcomings. To overcome these shortcomings, in the late 1960s and early 1970s he developed a horizontal multi-chamber fluidized dryer. The device is simple in structure, easy to operate, for a variety of difficult-dried powder and granular materials and heat-sensitive materials dry. Such as polyethylene, pesticides, artificial meat, copper sulfate, sodium chloride and the like. After decades of widespread application it shows the adaptability of various materials is better to strengthen the fluidized bed dryer, drying room for it than the box-type, small footprint, large capacity, high thermal efficiency, and dried After the product moisture uniformity. Compared to air drying, fluidized bed dryer operation by adjusting the stop loss less material in a fluidized bed, it was more widely used in recent years. But horizontal multi-chamber fluidized dryer thermal efficiency is lower than the multi-fluid bed dryer, especially when using hot air temperatures higher thermal efficiency will be even worse. While the wet material in the first and second chamber dryer is often easy to agglomerate, requiring constant cleaning.
