Description

Technical Field

[0001] The utility model relates to the technical field of flash evaporation devices, in particular to a flash evaporation device used for milk processing. Background Art

[0002] Flash evaporation is the phenomenon that after a high-pressure saturated liquid enters a relatively low-pressure container, due to the sudden drop in pressure, these saturated liquids become saturated vapor and saturated liquid under part of the container pressure. The boiling point of a substance increases with increasing pressure, and the lower the pressure, the lower the boiling point. In this way, the high-pressure and high-temperature fluid can be reduced in pressure to lower its boiling point and enter the flash tank. At this time, the fluid temperature is higher than the boiling point under the pressure. The fluid boils and vaporizes rapidly in the flash tank, and the two phases are separated.

[0003] The existing flash evaporation device for milk processing usually has a small contact area between milk and air, resulting in low flash evaporation efficiency of milk, so we propose a flash evaporation device for milk processing. Utility Model Content

[0004] The utility model aims to solve the disadvantage that the contact area between milk and air is small, which leads to low flash evaporation efficiency of milk, and proposes a flash evaporation device for milk processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flash evaporation device for milk processing comprises a base, a plurality of support columns are fixedly mounted on the base, a flash evaporation tank is fixedly connected to the support columns, a liquid inlet pipe is fixedly connected to the flash evaporation tank, a rotating mechanism is connected to the liquid inlet pipe, a vacuum mechanism is connected to the flash evaporation tank, a motor is fixedly connected to the flash evaporation tank, a transmission rod is fixedly connected to the output shaft of the motor, a liquid discharge pipe is fixedly connected to the flash evaporation tank, and a liquid discharge valve is fixedly connected to the liquid discharge pipe.

[0007] Preferably, the rotating mechanism includes a transmission pipe, a support frame and a plurality of nozzles, the transmission pipe is rotatably connected to the liquid inlet pipe, the support frame is rotatably connected to the flash tank, the support frame is fixedly connected to the transmission pipe, the nozzle is rotatably connected to the support frame, and the plurality of nozzles are all connected to the transmission pipe.

[0008] Preferably, the vacuum mechanism comprises a vacuum pump and a vacuum pipe, the vacuum pump is fixedly connected to the flash tank, the vacuum pipe is fixedly connected to the vacuum pump, and the vacuum pipe is fixedly connected to the flash tank.

[0009] Preferably, a large gear is fixedly connected to the transmission rod, a small gear is fixedly connected to the transmission tube, the large gear is meshingly connected with the small gear, and the transmission rod and the transmission tube are both rotatably connected to the same protective box.

[0010] Preferably, a filter screen is fixedly connected to the flash tank, and the transmission rod is movably connected to the support frame.

[0011] Preferably, a pressure reducing valve is fixedly connected to the liquid inlet pipe, and a heater is fixedly connected to the pressure reducing valve.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] (1) In this solution, since a support frame and multiple nozzles are provided, the pinion drives the transmission tube to rotate, the transmission tube drives the support frame to rotate, and the support frame drives the nozzle to rotate. The high-pressure saturated solution is sprayed into the flash tank through the nozzle, thereby increasing the contact area between the milk and the air, and the flash evaporation efficiency of the internal liquid is higher and the flash evaporation is more thorough.

[0014] (2) In this scheme, since a filter screen, a vacuum pump and an exhaust pipe are provided, the filter screen shields the liquid to prevent the liquid from bursting into the exhaust pipe. The vacuum pump extracts the gas in the flash tank out of the flash tank through the exhaust pipe, thereby maintaining a negative pressure state in the flash tank.

[0015] The utility model has the advantages of simple operation and convenient use, and can make the contact area between milk and air larger, thereby improving the flash evaporation efficiency of milk. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the utility model, when working, the milk is first heated by the heater 3 to make the raw material into a high-pressure saturated solution, and the high-pressure saturated solution enters the flash tank 2 through the pressure reducing valve 11 and the liquid inlet pipe 13. After the high-pressure saturated solution enters the transmission pipe 10 through the liquid inlet pipe 13, the motor 4 and the nozzle 15 are switched on, and the output shaft of the motor 4 drives the transmission rod 5 to rotate, and the transmission rod 5 drives the large gear 8 to rotate, and the large gear 8 drives the small gear 9 to rotate through the meshing connection with the small gear 9, and the small gear 9 drives the transmission pipe 10 to rotate, and the transmission pipe 10 drives the support frame 14 to rotate, and the support frame 14 drives the transmission rod 5 to rotate.
