Description

Technical Field

[0001] The utility model relates to the technical field of yeast production and processing equipment, in particular to a high-efficiency and energy-saving yeast metabolite top-spray fluidized bed. Background Art

[0002] The existing yeast metabolite drying system uses a fluidized bed, which transports liquid yeast metabolites to a spray assembly and sprays them on the top of the fluidized bed through the spray assembly. The drying is completed by high-temperature hot air provided by an air heat exchanger and cooled cold air at the discharge port. The steam energy consumption cost is high. In order to prevent the steam condensate from being directly discharged and the heat from being wasted, a heat exchange pipe is usually installed between the mesh plate and the spray assembly to recover the heat of the steam condensate.

[0003] The above process has the following problems:

[0004] Heat exchange tubes usually use single-segment straight lines or serpentine shapes. On the one hand, the heat exchange efficiency is poor and the internal space is not fully utilized to ensure the efficiency of heat recovery. On the other hand, the entire weight of the heat exchange tube is borne by the flanges where the pipe ends are connected, which can easily cause flange damage and lead to steam condensate leakage.
