Background

A fluidized bed is generally a machine for quickly drying wet materials, a vibration table is arranged in a container of the current mainstream fluidized bed, materials are placed on the vibration table, the materials are vibrated by the vibration table to be in a loose state, then hot air is introduced into the container to dry the materials, meanwhile, the materials are driven to be transported from one end to the other end by the vibration of the vibration table, so that the materials flowing into the container are continuously dried, the materials are generally dried by adopting smoke, namely, air with high temperature is quickly heated by means of thermal combustion and the like, then the high-temperature smoke is introduced into the container to dry the materials, but the materials with lower required temperature cannot be well dried, the pollution is large, and a large amount of heat is lost in the process of heating the air to higher temperature, the energy utilization rate is low, in order to better utilize heat, a low-wind-speed and low-wind-quantity flue gas supply method is generally adopted, but the moisture content in the flue gas is higher after the flue gas is dried for a period of time, so that the drying effect is poor. And the advancing mode of the belt-carrying animal materials has uncertainty, which can cause the phenomenon that the drying time of partial materials is longer and the drying time of partial materials is shorter, thereby causing the uneven drying degree.
