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 Great. To improve this situation, the development of a multi-layered fluid bed dryer. A multistage operation improves efficiency, 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 triflumizole dryer manufacturer, operating, dryer, difficult for a variety of dried powder dry granular materials and heat-sensitive materials. Such as polyethylene, pesticides, artificial meat, copper sulfate, sodium chloride and the like. After decades of widespread application it shows adaptability to a variety of materials, high technology soy lecithin 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, 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. Fluidized drying reason for widespread development, has the following advantages. Drying device itself does not include mechanical moving parts, thus low investment cost of the equipment, maintenance workload is small. Its main disadvantage is as follows. ① is the particle size of the dried material has certain requirements, generally require no less than 30 microns and not more than 4mm as appropriate. When several materials mixed with dry density should be close to a variety of materials. ② Since the fluidized dryer material backmixing more intense, a calcium phosphate dryer production line, so that in a single stage continuous fluidized drying apparatus, uneven material residence time, may occur without the dried material with the product discharge bed.
