The relevant process parameters can be adjusted according to different product characteristics, with the advantages of high efficiency and simple process. According to the different conditions of the owner, the drying and cooling process or fluidized bed drying + powder flow cooling process can be selected, which is well-adapted.

Internal heating fluidized bed dryer is a new drying technology developed on the basis of boiling fluidized bed drying and indirect heating drying. The tubular exchanger is immersed in the fluidized dry material. There is a hot (cold) medium in the built-in heat exchanger, and the heat required for material dehydration (cooling) is mainly provided by the built-in heat exchanger, so as to meet the requirements of material fluidization with a small air volume.Fluidizing medium mainly carries water and maintains the normal fluidization of bed particles. The drying (cooling) process is mainly built-in heat exchanger and two-phase flow of heat transfer and two-phase flow between the heat and mass transfer process.
