The sterile air compression system is responsible for providing sterile air to the tank to maintain the stability of the environment inside the tank.

[0031] What is not shown in the figure is that the pipes and connectors used for connection in this application are made of high-quality materials to ensure that the system will not leak during use, thereby ensuring the stability and sterility of the environment inside the tank.

[0032] The specific steps are:

[0033] Initialization of sterile air pressure maintenance system in the aging tank area:

[0034] 1. Check whether all automatic valves are in automatic state. If they are in manual state, the program will be suspended and the next step will be entered normally. If they are not normal, the alarm program will be suspended and the problem will be solved. After the problem is solved, reset the valve. If the test is normal, the next step can be entered.

[0035] 2. Check the pressure sensor on the top of the aging tank. If it is normal, proceed to the next step. If it is abnormal, the alarm will be paused and the problem will be solved. After the problem is solved, reset it. If the test is normal, you can proceed to the next step.

[0036] 3. Check the air supply valve on the top of the aging tank, the negative pressure valve of the respirator and the butterfly valve of the CIP respirator. If normal, proceed to the next step. If abnormal, an alarm will be issued and select "Continue". If yes, proceed to the next step; if no, pause;

[0037] 4. Check the feedback of the negative pressure valve of the respirator on the top of the aging tank. If normal, proceed to the next step. If abnormal, an alarm will be triggered and select "Do you want to continue". If yes, proceed to the next step, otherwise pause.

[0038] Aging tank inlet and outlet:

[0039] 1. The pressure in the aging tank is always maintained between 1000-1500pa;

[0040] 2. When the aging tank is fed, the pressure sensor monitors the pressure inside the tank. When the pressure inside the tank is greater than the set 1000Pa, the positive pressure valve plate of the tank top respirator automatically pops up. In special cases, when the pressure inside the tank continues to rise to above 2000Pa, the possible reason for this situation is that the positive pressure valve plate is frozen or cannot be opened due to mechanical failure. The feeding program is stopped and the negative pressure valve plate is forced to open at the same time. After the pressure is released to 1500Pa, it is closed. The program alarms and repairs are carried out.

[0041] 3. When the aging tank is unloading, the pressure sensor monitors the pressure inside the tank. When the pressure inside the tank is lower than the set 1000pa, the air supply valve on the top of the tank is opened to replenish air. When the pressure reaches 1500pa, the air supply valve is closed. Special cases: When the air supply valve on the top of the tank cannot be opened, the unloading program stops and the alarm is triggered for maintenance; if the pressure continues to drop below -500pa at this time, the unloading program stops and the alarm is triggered for maintenance; when the pressure continues to drop below -1000pa, the negative pressure valve plate automatically pops up, the unloading program stops, and the alarm is triggered for maintenance; if the pressure continues to drop below -1500pa at this time, the negative pressure valve plate is forced to open, the program alarms and maintenance is triggered.

[0042] When the CIP cleaning process of the aging tank and the ambient temperature cause the pressure inside the tank to change:

[0043] 1. The pressure in the aging tank is always maintained between 1000-1500pa;

[0044] 2. Before the aging tank is CIP cleaned, the program is set to pneumatically open the negative pressure valve plate to check whether the negative pressure plate feedback of the respirator on the top of the aging tank is working normally. If it is normal, proceed to the next step. If it is not normal, an alarm will be issued;

[0045] 3. When the aging tank is CIP cleaned, the program sets the pneumatic butterfly valve for respirator cleaning to open intermittently according to the cleaning medium - the min time can be edited, and cold cleaning is not allowed for tank cleaning CIP;

[0046] 4. When the aging tank is CIP cleaned, the program sets that the tank washing only uses hot washing, that is, hot alkali / hot water washing or only hot water cleaning program is optional, and then the temperature is naturally cooled. Cold water cleaning is not allowed, and refrigerant cooling is not allowed. The program strictly prohibits the use of cold water to wash the tank. If there is any wrong operation, an alarm will be immediately issued and the cleaning program will be stopped;

[0047] The pressure sensor monitors the pressure inside the tank. When the pressure inside the tank is greater than the set 1500Pa, the positive pressure valve plate of the tank top respirator automatically pops up. In special cases, when the pressure inside the tank continues to rise to more than 2000Pa, the possible reason for this situation is that the positive pressure valve plate is frozen or mechanical failure cannot be opened. The cleaning program is stopped, and the negative pressure valve plate is forced to open at the same time. After the pressure is released to 1500Pa, it is closed. The program alarms and repairs are carried out.

[0048] After the hot wash, the tank naturally cools down, causing the pressure inside the tank to decrease. The pressure sensor 107-PT-P10300101 monitors the pressure inside the tank. When the pressure inside the tank is lower than the set 1000pa, the air supply valve on the tank top is opened to supply air. When the pressure reaches 1500pa, the air supply valve is closed. In special cases, when the pressure drops below 0pa and opening the air supply valve is ineffective, an alarm is issued for maintenance. If the pressure continues to drop below -650pa at this time, the negative pressure valve plate automatically pops up. If the pressure continues to drop below -1000pa at this time, the negative pressure valve plate is forced to open, and the program alarms and performs maintenance. After the maintenance is completed and reset, the tank body is cleaned again.

[0049] 5. When the pressure in the tank decreases due to changes in environmental conditions, the pressure sensor monitors the pressure in the tank. When the pressure in the tank is lower than the set 1000pa, the air supply valve on the top of the tank is opened to supply air. When the pressure reaches 1500pa, the air supply valve is closed. In special cases, when the pressure drops below 0bar and opening the air supply valve is ineffective, an alarm is issued for maintenance. If the pressure continues to drop below -650pa at this time, the negative pressure valve plate automatically pops up. If the pressure continues to drop below -1000pa at this time, the negative pressure valve plate is forced to open, and the program alarms and performs maintenance.

[0050] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
