Combined with Figure 3 The rear end of the suction gun 9 is clamped by the automatic manipulator 10, and the suction gun 9 is axially sent into the tubular cleaning and sterilization equipment 8 by the automatic manipulator 10, or the suction gun 9 that has been cleaned is axially drawn out from the tubular cleaning and sterilization equipment 8 by the automatic manipulator 10, so as to realize the connection and separation of the suction gun 9 and the tubular cleaning and sterilization equipment 8. The tubular cleaning and sterilization equipment 8 realizes regional functional isolation through the wall 7.

[0023] The present invention also provides a method for online cleaning and sterilization of a suction gun of a vacuum freeze dryer using the above system, the steps of which are as follows: after the automatic manipulator 10 moves the suction gun 9 and connects the tubular cleaning and sterilization equipment 8, the cleaning water inlet valve 2 is opened, and the cleaning water enters the tubular cleaning and sterilization equipment 8 through the stainless steel pipe, the hose 11, and the suction gun 9, and the overflow valve 5 and the drain valve 3 of the drain outlet are opened. After three minutes, the drain valve 6 is opened. After cleaning until the set time, all valves are reset and closed, and the cleaning process is completed. After the cleaning is completed, the steam inlet valve 1 is opened, and pure steam enters the tubular cleaning and sterilization equipment 8 through the stainless steel pipe, the hose 11, and the suction gun 9, and the drain valve 6 and the drain valve 3 of the drain outlet are opened. After the temperature of the temperature probe 4 reaches 121 degrees and is maintained for the set time, the sterilization process is completed.
