[0029] In the embodiment, the first liquid level detection sensor 17 is a tuning fork liquid level detection sensor, and the controller is a PLC module or a single-chip microcomputer or an industrial computer.

[0030] The utility model can realize at least the following working processes:

[0031] When CIP backwashing of the wort heat exchange sheet 1 is required according to the process,

[0032] Firstly, blowdown is performed, the controller controls to open the wort come pipe blowdown valve 10, the wort out pipe blowdown valve 15 and the anti channeling blowdown total valve 18, and to close the wort come valve 6, the wort inlet sheet stop valve 7, the wort out sheet stop valve 11, the wort out valve 12, the CIP backwash return valve 8 and the CIP backwash come valve 13, so as to empty the wort come pipe blowdown pipe 9 and the wort out pipe blowdown pipe 14 and avoid false signals of the first liquid level detection sensor 17 caused by residual liquid;

The controller automatically closes the CIP backwash return valve 8 and the CIP backwash inlet valve 13 immediately, stops the CIP backwash operation and outputs an alarm, so as to achieve the purpose of detection and control of CIP backwash anti-channeling of the heat exchange sheet during production, and avoid the occurrence of a serious economic loss situation caused by channeling of CIP liquid into wort.

The CIP backwash return pipe 3 between the shunt pipe 19 and the heat exchange wort inlet pipe 2 is provided with a CIP backwash return pressure sensor 22. The controller is electrically connected to the CIP backwash inlet pressure sensor 21 and the CIP backwash return pressure sensor 22.

[0037] When the wort heat exchange sheet 1 backwash starts, the shunt valve 20 opens to shunt a part of the CIP cleaning liquid, so as to prevent the wort heat exchange sheet 1 from being damaged by a larger pressure when there is a blockage. When the detected pressure difference of the CIP backwash inlet pressure sensor 21 and the CIP backwash return pressure sensor 22 meets the requirements, the shunt valve is closed, and all the CIP cleaning liquid passes through the wort heat exchange sheet 1.

[0038] In one embodiment, as shown in Figure 3 , Figure 4 , the CIP backwash inlet pipe 5 is provided with a preheater 23. The CIP backwash inlet pipe 5 between the preheater 23 and the CIP backwash inlet valve 13 is provided with a temperature sensor 24.

[0040] In one embodiment, as shown in Figure 5 A second liquid level detection sensor 31 is arranged on the heat exchange wort inlet pipe 2 between the wort inlet thin plate stop valve 7 and the wort inlet pipe blowdown pipe 9, and a third liquid level detection sensor 32 is arranged on the heat exchange wort outlet pipe 4 between the wort outlet thin plate stop valve 11 and the wort outlet pipe blowdown pipe 14, and the controller is electrically connected with the second liquid level detection sensor 31 and the third liquid level detection sensor 32. The second liquid level detection sensor 31 and the third liquid level detection sensor 32 are both tuning fork liquid level detection sensors. By arranging the second liquid level detection sensor 31 and the third liquid level detection sensor 32, it can be more convenient to distinguish whether the CIP cleaning liquid leakage exists in the input end or the output end, that is, which liquid level detection sensor detects a signal, indicating that the CIP cleaning liquid leakage exists in the end.
