Description

Technical Field

[0001] The utility model relates to the technical field of concentrators, in particular to a continuous feeding type double-effect concentrator. Background Art

[0002] Double-effect concentrator is suitable for low-temperature vacuum concentration of heat-sensitive materials such as traditional Chinese medicine, western medicine, glucose, brewing, starch, oral liquid, chemical industry, food, monosodium glutamate, dairy products, etc. The series concentrators in the technical parameters can be selected according to the amount of concentration. The double-effect concentrator adopts two-effect simultaneous evaporation, and the secondary steam is fully utilized, which saves the investment in boilers and saves energy consumption.

[0003] After searching, the publication number is: CN214158558U. A double-effect concentrator comprises a first-effect heater, a first-effect evaporator, a second-effect heater and a second-effect evaporator. A first conduit is connected between the first-effect heater and the bottom end of the first-effect evaporator, a third conduit is connected between the second-effect heater and the bottom end of the second-effect evaporator, a second conduit is connected between the top of the first-effect evaporator and the upper end of the side wall of the second-effect heater, and a fourth conduit is connected at the middle position of the top of the second-effect evaporator. The utility model adds a first annular cleaning pipe, a second annular cleaning pipe, a connecting pipe and a water spraying port, etc. When the evaporator needs to be cleaned, cleaning water can be added from the water adding pipe, and the cleaning water can be sprayed on the inner wall of the evaporator from the water spraying ports evenly opened on the first annular cleaning pipe and the second annular cleaning pipe, which can effectively increase the thoroughness and uniformity of the evaporator cleaning and improve the cleaning efficiency.

[0004] However, the device has the following disadvantages: although the above device can add cleaning water from the water adding pipe when the evaporator needs to be cleaned, the cleaning water can be sprayed onto the inner wall of the evaporator from the water spray ports evenly opened on the first annular cleaning pipe and the second annular cleaning pipe, which can effectively increase the thoroughness and uniformity of the evaporator cleaning and improve the cleaning efficiency, but in practice, the device uses a sealed door to add raw materials to the heater, which usually cannot achieve true continuous feeding, because each time the door is opened, it will cause a short interruption. Without a continuous feeding system, the concentration process will be interrupted and unstable, affecting the concentration efficiency.

[0005] Therefore, in view of the above problems, a continuous feeding double-effect concentrator is proposed. Utility Model Content
