Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a high-efficiency water evaporation tank. Background Art

[0002] In current evaporation tanks for evaporating water from sugar solution in natto food processing, high-temperature steam is passed through a heating drum inside the tank to heat the sugar solution to boiling. To improve the heat exchange efficiency of the heating drum, the evaporation tank is usually designed as a slender structure. This reduces the liquid-gas interface area inside the evaporation tank, which is not conducive to the evaporation of water from the sugar solution. In addition, the existing evaporation tanks use a set of heating devices to heat the sugar solution during operation, resulting in a long heating time. At the same time, most devices are not equipped with corresponding stirring devices, which easily causes uneven heating and stirring of the sugar solution during the heating process. To solve the above problems, the present application proposes a high-efficiency water evaporation tank. Utility Model Content
