[0041] The working principle of the embodiment is briefly described as follows:

[0042] The utility model uses the CIP tank body itself as the cleaning liquid preparation tank, and is provided with the pipeline, valve and pump required for self-cleaning, and the related software program is prepared, so that the self-circulation and self-cleaning purposes are achieved.

[0043] First, add CIP tank self-cleaning control program on the fermenter control cabinet. Before starting the program, the operator calculates the required amount of alkali and adds it to the CIP tank, and then starts the CIP tank self-cleaning control program. The program will automatically execute the following steps:

[0044] Step 1, alkali preparation: close the first pneumatic valve 12, the third pneumatic valve 14, the fourth pneumatic valve 15, the fifth pneumatic valve 16, the sixth pneumatic valve 17 and the power pump 7, open the second pneumatic valve 13 and the stirring, inject water pipeline 4 into the tank, the CIP tank 1 has a stirring function, which increases the speed of alkali dissolution, and makes the alkali and water evenly mixed.

[0045] Step 2, alkali circulation: close the second pneumatic valve 13 and the stirring, open the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7, the alkali starts to circulate through the cleaning branch 16 and the cleaning return pipeline 2 to clean the CIP tank.

[0046] After the circulation is completed, close the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7, open the third pneumatic valve 14, and drain the alkali in the tank.

[0047] Step 3, purified water cleaning: when the liquid level meter detects that the alkali in the tank is drained, close the third pneumatic valve 14, inject purified water into the tank by opening the first pneumatic valve 12, and open the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7. When the liquid level meter detects that the injected purified water reaches the set liquid level, close the first pneumatic valve 12, the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7, open the third pneumatic valve 14, and close the third pneumatic valve 14 when the purified water in the tank is drained. This step is repeated 3 times.

[0048] Step 4, injection water cleaning: when the liquid level meter detects that the purified water in the tank is drained, close the third pneumatic valve 14, add injection water to the tank by opening the second pneumatic valve 13, and open the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7. When the liquid level meter detects that the injected injection water reaches the set liquid level, close the second pneumatic valve 13, the fourth pneumatic valve 15, the sixth pneumatic valve 17 and the power pump 7, open the third pneumatic valve 14, and close the third pneumatic valve 14 when the injection water in the tank is drained.

[0049] Step 5, cleaning end: when the pH sensor detects that the pH of the cleaning liquid in the tank is less than 7, close the self-cleaning program, and the cleaning is completed.

[0050] Take the use of 100L 1mol / L alkali to clean the CIP tank as an example:

[0051] The calculated amount of alkali: 100L*1mol / L*40g / mol=4000g, the operator adds the calculated amount of alkali (4000g) into the CIP tank, and starts the CIP self-cleaning program;

[0052] The program will automatically execute the above steps 1-5, after the third execution of step 3, the alkali solution has been basically cleaned, and the purpose of this step is to reduce the amount of subsequent injection water, because the real cleaning of the alkali is the injection water, which greatly reduces the amount of injection water, and in turn reduces the cost. When the pH sensor detects that the liquid flowing reaches the set pH value, the system automatically terminates the program, at this time all valves will be in the closed state.

[0053] The CIP tank after cleaning has been circulated by the alkali solution, so that the disadvantages of cleaning dead angle that may exist in the traditional alkali cleaning method can be avoided, and the cleaning degree is improved. During the cleaning process, whether it is alkali, purified water or injection water, it is sprayed and cleaned by the spray ball. In addition, through the set self-cleaning program, after starting the program, combined with the structure of the circulating cleaning system, the operator only needs to calculate the alkali and add it into the CIP tank, and after starting the program, the operator does not need to watch all the time, which greatly saves the human resources.

[0054] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
