[0028] The working principle of the present invention is as follows:

[0029] After the liquid preparation tank 1 is normally prepared, the liquid outlet pneumatic valve 12 and the liquid preparation valve 61 are opened, and the second delivery pump 64 is started to fill the liquid product prepared in the liquid preparation tank 1 into the production liquid storage tank 2 for storage until the liquid in the production liquid storage tank 2 reaches the preset high liquid level, and the liquid replenishment is stopped. When the liquid in the production liquid storage tank 2 is consumed to the preset low liquid level, the liquid preparation tank 1 automatically replenishes the production liquid storage tank 2.

[0030] When the liquid in the liquid preparation tank 1 is consumed to a low level, the system automatically alarms and reminds, closes the liquid outlet pneumatic valve 12 and the second delivery pump 64, and then replenishes the liquid in the liquid preparation tank 1. When the liquid level in the liquid preparation tank 1 reaches the preset high level, the liquid replenishment is stopped, and the automatic stirring of the liquid preparation tank 1 is turned on to stir the liquid evenly, waiting for the filling operation of the production storage tank 2 to be carried out again.

[0031] See attached Figure 1 The two liquid storage tanks 2 on the left side, taking a liquid dispensing system in which one liquid storage tank 2 is equipped with one liquid dispensing tank 1 as an example, can be manually cleaned in the following three ways:

[0032] a. Manual pure water cleaning steps: open the pure water valve 51 of the liquid supply system to release water →→ when the liquid level of the liquid dispensing tank 1 reaches the set upper limit →→ close the pure water valve 51 →→ manually open the stirring motor in the liquid dispensing tank 1 →→ manually open the first liquid return valve 63 and the second liquid return valve 13 →→ manually open the bottom liquid outlet pneumatic valve 12 →→ manually open the liquid pumping motor of the second delivery pump 64 →→ circulate the return liquid pipeline 7 until the preset time is reached →→ manually close the liquid outlet pneumatic valve 12, the first liquid return valve 63, the second liquid return valve 13, the second delivery pump 64, and the stirring motor in the liquid dispensing tank 1 →→ open the drain valve of the liquid dispensing tank 1 to release water →→ alarm when the preset cleaning low liquid level is reached →→ manually close the drain valve.

[0033] b. Manual hot water cleaning steps: open the hot water valve 41 to release hot water →→ when the liquid level in the liquid dispensing tank 1 reaches the set upper limit →→ the hot water valve 41 is closed →→ manually open the stirring motor in the liquid dispensing tank 1 →→ manually open the first liquid return valve 63 and the second liquid return valve 13 →→ manually open the bottom liquid outlet pneumatic valve 12 →→ manually open the liquid pumping motor of the second delivery pump 64, →→ circulate the liquid return pipeline 7 until the preset time is reached →→ manually close the liquid outlet pneumatic valve 12, the first liquid return valve 63, the second liquid return valve 13, the second delivery pump 64, and the stirring motor in the liquid dispensing tank 1 →→ open the drain valve of the liquid dispensing tank 1 to release water →→ an alarm is sounded when the preset cleaning low liquid level is reached →→ manually close the drain valve.

[0034] c. The steps of manual pipeline disinfection are as follows: open the pure water valve 51 of the liquid supply system to release water →→ when the liquid level of the liquid preparation tank 1 reaches the set upper limit →→ close the pure water valve 51 →→ add a certain proportion of disinfectant →→ manually open the stirring motor in the liquid preparation tank 1 →→ manually open the first return liquid valve 63 and the second return liquid valve 13 →→ manually open the bottom liquid outlet pneumatic valve 12 →→ manually open the pumping motor of the second delivery pump 64, →→ circulate the return liquid pipeline 7 until the preset time is reached →→ manually close the liquid outlet pneumatic valve 12, the first return liquid valve 63, the second return liquid valve 13, the second delivery pump 64, and the stirring motor in the liquid preparation tank 1 →→ open the drain valve of the liquid preparation tank 1 to release water →→ alarm when the preset cleaning low liquid level is reached →→ manually close the drain valve.

[0035] You can also use the following method to perform automatic cleaning. The specific steps are as follows:

[0036] During automatic cleaning, the above three manual steps will run automatically. The working principle is as follows: After the parameters are set, press a button to clean →→ the pure water valve 51 opens to automatically drain water →→ set time →→ the drain valve opens →→ the drainage reaches the set time →→ close the drain valve →→ the set water level is reached in the liquid distribution tank 1 →→ close the pure water valve 51 →→ automatic stirring in the liquid distribution tank 1 →→ automatically open the pumping motor of the second delivery pump 64 →→ open the first return liquid valve 63 and the second return liquid valve 13 →→ the return liquid pipeline 7 circulates →→ reaches the set time →→ close the circulation →→ the drain valve opens again to drain →→ the low set water level is reached in the liquid distribution tank 1 →→ automatically open the hot water circulation (same as the above manual hot water cleaning steps, only change the manual to automatic) →→ after the hot cycle is completed →→ open the pure water circulation (same as the above manual pure water cleaning steps, only change the manual to automatic) →→ after the pure water circulation is completed →→ end and automatically close all functions.

[0037] See attached Figure 1 The three liquid storage tanks 2 on the right side take the liquid dispensing system in which one liquid storage tank 2 is equipped with two liquid dispensing tanks 1 as an example, and the two liquid dispensing tanks 1 are respectively recorded as liquid dispensing tank A and liquid dispensing tank B. The operation can be carried out in the following manner:

[0038] Cleaning and disinfection: ① Start one-button cleaning, the pure water valve 51 of the A and B liquid dispensing tanks automatically opens, and the pure water starts to rinse the tank body. After 2 minutes, the bottom drain valve automatically opens to drain. After ten minutes of flushing, the pneumatic valves of the A and B tanks automatically close. After 2 minutes, the drain valve automatically closes, and the pure water valve 51 automatically opens and automatically closes after the pure water reaches a certain liquid level. At the same time, the liquid outlet pneumatic valve 12 of the A and B liquid dispensing tanks, the first liquid return valve 63 of the liquid storage tank 2, and the liquid pumping motor of the second delivery pump 64 automatically open, and the second liquid return valve 13 (return diaphragm valve) of the A and B liquid dispensing tanks is adjusted to the same flow rate of the two tanks. After 30 minutes of cyclic cleaning, the liquid pumping motor of the second delivery pump 64 is closed, and the drain valve automatically opens to drain the pure water in the A and B liquid dispensing tanks (the time can be set).

[0039] ② Repeat step ① with hot water cleaning and disinfection (all steps are completed automatically).

[0040] ③Repeat step ① with pure water.

[0041] Liquid preparation: Start draining water from liquid preparation tank A, open the pure water valve 51 on the tank body, drain water to the set liquid level of liquid preparation tank A, then manually start the stirring motor in liquid preparation tank A, add raw materials (manually), click the automatic button, and stir for the set time. When liquid storage tank 2 gives a low liquid level signal to liquid preparation tank A, the liquid outlet pneumatic valve 12 automatically opens, and the pumping motor of the second delivery pump 64 starts. After liquid is prepared until liquid storage tank 2 reaches the set high liquid level, a liquid level signal is given to liquid preparation tank A, and the pumping motor of the second delivery pump 64 is turned off. When the liquid in liquid preparation tank A gives a low liquid level signal, the pumping motor of the second delivery pump 64 is turned off, and the liquid outlet pneumatic valve 12 at the bottom of liquid preparation tank A is automatically closed. Manually switch to liquid preparation tank B, and repeat the above steps for liquid preparation tank A.
