Embodiment
In the present embodiment, anti-channeling liquid plate heat exchanger 1 is mainly used in in vegetable fat powder production process, after shearing sterilizes
Vegetable fat powder feed liquid heat exchange cooling.Hydrothermal solution in hot flow path 10 is vegetable fat powder feed liquid, is cold water in cold runner 20, passes through cold water
Heat absorption, the heat release of vegetable fat powder feed liquid, so as to have the function that cool down vegetable fat powder feed liquid.
By suction pump after the shearing sterilizing that the feed liquid of vegetable fat powder passes through shear cylinder 2, the feed liquid in shear cylinder 2 is extracted into anti-
Alter and exchanged heat in the hot flow path 10 of liquid plate heat exchanger 1.Inlet one end of runner is provided with proportional flow control valve 30.When first
When the pressure that pressure sensor 11 senses is less than the pressure that second pressure sensor 21 senses, i.e., the pressure of hot flow path 10 is less than cold
The pressure of runner 20, there is the risk that cold water alters liquid into hydrothermal solution, now the aperture of proportional flow control valve 30 increase on hot flow path 10, companion
With the pressure rise of hot flow path 10.The one end of hot flow path 10 connects with shear cylinder 2, and the other end connects with high pressure homogenizer 3.
It is appreciated that anti-channeling liquid plate heat exchanger 1 also includes controller, controller and first pressure sensor 11, second
Pressure sensor 21 and proportional flow control valve 30 are electrically connected with, first pressure sensor 11, second pressure sensor 21 and ratio stream
Amount valve 30 together constitutes pressure closed-loop control system, sets up the pressure between hot flow path 10 and cold runner 20 so that hot flow path
Pressure on 10 is not less than the pressure in cold runner 20.
Specifically, when the pressure of the sensing of first pressure sensor 11 is less than second pressure sensor 21, hot flow path 10
The aperture increase of the proportional flow control valve 30 of inlet, the pressure loss for flowing through proportional flow control valve 30 reduce, proportional flow control valve 30
Pressure increase after valve, i.e., the pressure increase in hot flow path 10.
The proportional gradual increase aperture of proportional flow control valve 30, until first pressure sensor 11 sense pressure be equal to or
Slightly larger than second pressure sensor 21 pressure when, the aperture of proportional flow control valve 30 stops increase.
It is can solve the problem that using the pressure closed-loop control system of which due to feed liquid supply or cooling water circulation pressure change
Liquid problem is altered caused by imbalance of pressure so that anti-channeling liquid plate heat exchanger between caused hot flow path 10 and cold runner 20
1 has excellent anti-channeling liquid characteristic.

In another embodiment, the pressure that the first pressure sensor 11 is sensed is less than the second pressure sensor
During the pressure of 21 sensings, the circular flow of the circulating pump 50 reduces, so that the pressure in cold runner 20 reduces, it is suppressed that
Cold water is scurried into hydrothermal solution.
In a further example, the water inlet of cold runner 20 is provided with proportional flow control valve 30, when first pressure sensor 11 is felt
When the pressure measured is less than the pressure of second pressure sensor 21, the aperture of the proportional flow in cold runner 20 reduces, and flows through ratio
The pressure loss of example flow valve 30 is big, and the pressure in cold runner 20 reduces.Proportional flow control valve 30 it is proportional be gradually reduced aperture,
When the pressure of the sensing of first pressure sensor 11 is equal or slightly larger than the pressure of second pressure sensor 21, proportional flow control valve
30 aperture stops reducing.
The anti-channeling liquid plate heat exchanger 1 of the present embodiment also includes chilled water system, and the cold runner 20 connects the cold water system
System, the chilled water system include temperature sensor 60 and refrigeration machine 70, and the temperature sensor 60 is used to sense the cold runner
Water temperature in 20.When the water temperature that the temperature sensor 60 senses in the cold runner 20 is higher than default water temperature, the refrigeration
Machine 70 works to freeze to the water in the cold runner 20.
Above-mentioned, the temperature sensor 60 and refrigeration machine 70 of chilled water system constitute a kind of closed loop thermal control system, cold flow
Cold water in road 20 raises with temperature after hydrothermal solution progress heat exchange, by temperature sensor 60 and the moment of refrigeration machine 70 to cold water
Water temperature in system is regulated and controled so that anti-channeling liquid plate heat exchanger 1 has a preferable heat exchange efficiency all the time.
Also referring to Fig. 2 and Fig. 3, the anti-channeling liquid plate heat exchanger 1 include strap 101, ambulatory splint 102,
