Description

Technical Field

[0001] This utility model relates to the field of disinfection in fermented milk production, specifically to a disinfection device for fermented milk production. Background Technology

[0002] Chinese utility model patent application number 202322334347.7 proposes a sterilization device for fermented milk production. It first turns on a water pump to inject water into a hot water pipe and a cold water pipe respectively. The heating pipe heats the water, and the hot water flows into a copper pipe to pasteurize the emulsion. Adjusting the temperature control valve can mix the water in the hot water pipe and the cold water pipe, thereby regulating the water temperature and raising or lowering the temperature of the emulsion. This effectively prevents the filter from being damaged due to excessively rapid heating or cooling.

[0003] However, it still has some shortcomings:

[0004] First, the shape and structure of its copper tubes are relatively simple, which cannot guarantee that the fermented milk inside can be evenly heated and sterilized, resulting in uneven heating and sterilization and low overall sterilization efficiency.

[0005] Second, it lacks a structure for fully mixing hot and cold water, which easily leads to uneven mixing of hot and cold water, making it difficult to control the disinfection temperature and causing large temperature fluctuations.

[0006] Third, although it is equipped with a structure for cleaning the filter membrane, it cannot clean the disinfection tank and the internal copper pipes in a timely manner, which can easily lead to the adhesion of fermented milk on the inner wall of the disinfection tank, affecting subsequent disinfection operations, and also affecting the already cleaned filter membrane.

[0032] Furthermore, the two outlet pipes 13 are inclined, parallel and do not intersect, and are centrally symmetrical.

[0033] Furthermore, the upper end of the mixing tank 14 is connected to a water inlet pipe 7, the other end of the water inlet pipe 7 is located on the lower side of the outer shell 1 and is connected to a rotary joint 6. The water tank 9 is also connected to a return water pipe 15, the other end of the return water pipe 15 is connected to the rotary joint 6, and the return water pipe 15 is also connected to an air cooler 32.

At the same time, water is supplied from the water supply pipe 26 and enters the annular cleaning pipe 28 through the high-pressure telescopic pipe 27. The water is then sprayed through the nozzle to rinse and clean the inner wall of the outer shell 1 and the outer surface of the disinfection frame 31. Meanwhile, the water flows to the filter membrane 2 to rinse the filter membrane 2. Impurities that cannot pass through the filter membrane 2 are discharged through the water outlet pipe 4.

[0047] After cleaning is completed, the electric telescopic rod 30 drives the annular cleaning pipe 28 to return, and the high-pressure telescopic pipe 27 automatically retracts.
