Energy use is not sufficiently fluidized bed drying equipment exists the problem of insufficient energy use, leading to the drying efficiency is not ideal, increase energy consumption. If the material in a fluidized drying process and close contact of hot air fluidized bed dryer consultation, there is the problem of incomplete heat exchange, not only reduces the drying efficiency, and increased energy consumption. GEA Group, a subsidiary of Germany [1] specially designed intake air more evenly and smooth the sieve, sieve allows the flow of heat exchange in the drying process more fully and reasonable, and reducing the energy consumption of heated air generated , fluidized bed dryer repair, can significantly enhance the economic efficiency. Sulzer of Switzerland and Japan Nara Machinery [2] Production of built-in heat pipe fluid bed dryer, fluidized bed heat all changed in the past by the hot air into the method, it will tubular heat exchanger immersed in the stream State of the dried material, the material required heat of dehydration are supplied with hot air from the heat exchanger and the fluidizing pipe, with a smaller amount of air drying to meet the requirements of the stream, since some of the heat from the heat transfer tube heat medium conducting , thus greatly improving the thermal efficiency, and the heat medium is usually steam, oil and so on. In addition, we can also use a new heating technology or new energy to improve the thermal efficiency of the equipment. As the heat transfer tubes implanted in the bottom of the bed, fluid bed drying machine cleaning, the use of the latent heat of liquid spray heat exchange, the use of microwave heating and other forms of further improve the thermal efficiency of the fluidized bed drying equipment, thereby reducing energy consumption, to achieve the purpose of the economic environment ??? 2.3 drying effects of differences in the prevalence of current fluidized bed drying drying results are quite different questions: (1) the same kind of material, there is a difference in the results of different feeding amount of drying; (2) different types of materials, the same feeding amount of dried The results are quite different. Therefore, for these two problems are generally improve the structure of the fluidized bed, it is more reasonable design, thereby increasing the variety of dry materials, fluid bed dryer, and can improve the drying efficiency and reduce drying results difference. German GEA Group [5] for the same kind of material, feeding amount of different drying results different problems, the design is suitable for two cylindrical fluidized bed dryer smaller amounts of dry material, for medium-sized dried amount of four fluid bed dryer in series and three rectangular fluid bed dryer and dried for large-scale amount. For different types of materials, the same feeding amount of drying results of different issues, designed specifically applies to a fluidized drier easy to join the solid material and suitable for liquid material drying fluidized dryer. Germany Glatt company [6] for the same kinds of materials, different feeding amount of drying results different problems, the design of batch and continuous fluidized bed fluidized bed, batch-type production capacity of 2 kg / h ~ 1.5 t / h, Continuous production capacity of 20 kg / h ~ 5 t / h, this design can effectively solve the same kinds of materials, different feeding amount of drying results different issues. Fluidized bed dryer maintenance, further dried (certified), fluidized bed dryer step by Changzhou Drying Equipment Co., Ltd. Drying Equipment Co. Changzhou step (www.yibu.com) is a leader in Changzhou, Jiangsu, drying equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In step drying leadership with the staff warmly welcome all inquiries negotiations to create a better future for the drying step.
