[0002] In the process of milk processing, in order to improve the taste and quality of dairy products, many dairy product production or processing companies will flash evaporate the milk to increase the solid content of milk and make the milk more fragrant, which requires a flash evaporator for dairy processing.

[0003] According to the description of a flash evaporation device for milk processing disclosed on the patent website (authorization announcement number: CN210017690U), "The utility model discloses a flash evaporation device for milk processing, including a tank body, a feed pipe, a drain pipe and a steam pipe. The steam pipe is connected to the top of the tank body through an insertion, and the steam pipe includes a cylindrical tube and an annular water collecting plate. The middle part of the cylindrical tube is fixedly connected to the top of the tank body through an insertion, and the inner wall of the cylindrical tube is conical. The annular water collecting plate is fixedly connected to the bottom end of the cylindrical tube. A water collecting trough is provided in an annular shape at the top of the annular water collecting plate, and the bottom end of the inner wall of the cylindrical tube fits with the top of the inner wall of the water collecting trough. The utility model can increase the contact area with steam by setting the inner wall of the cylindrical tube to a cone shape, so that the water in the steam contacts the inner wall of the cylindrical tube and liquefies and then flows into the water collecting trough of the annular water collecting plate, thereby greatly eliminating the water mixed in the steam, reducing the corrosion of the steam to the steam pipe, so that the operator does not need to stop the machine frequently for maintenance and replacement, and improves the flash evaporation efficiency of milk."

However, in actual use, the milk directly enters the tank body for flash evaporation, and the flash evaporation efficiency is relatively low. Therefore, it is necessary to improve a flash evaporator for dairy processing to solve the above problems. Utility Model Content
