Technical Field

[0002] Some products in the food industry need to be filled with BIB equipment. During filling, the existing BIB filling equipment opens the valve core of the filling head, and the material will flow out from the four sides of the valve core and be filled into the sterile bag. When filling stops, the filling valve closes, and there will still be a certain amount of residual material in the filling head. At this time, the filling head moves upward to reset. Before the next filling, the remaining filling liquid in the filling head is likely to drip outside the filling port of the sterile bag or onto the filling platform, bringing potential risks of microbial growth. If the dripping position is at the bag opening, it may cause subtle sealing problems and microbial growth at the bag opening, which in turn brings potential food quality risks.

[0044] In a specific example, the residual liquid collection mechanism 5 includes a residual liquid collection cylinder 51 and a residual liquid collection trough 52. The residual liquid collection cylinder 51 is electrically connected to the controller and the cylinder body of the residual liquid collection cylinder 51 is fixed to the lower side wall of the filling bin 2. The piston rod of the residual liquid collection cylinder 51 is arranged parallel to the slide 1 and extends into the filling bin 2.

[0051] Specifically, a baffle 97 is fixed at the bottom of the push rod 93, and the baffle 97 can abut against the top of the bag cover to prevent the push rod 93 from damaging the bag cover during the opening and closing process.

The disinfectant storage tank 101 is connected to the atomizing nozzle 103 via the disinfectant delivery pipeline 102. The disinfectant output solenoid valve 104 is mounted on the disinfectant delivery pipeline 102 and electrically connected to a controller. The disinfectant storage tank contains hydrogen peroxide. When the sterile bag opening enters the filling chamber 2, it is disinfected with atomized hydrogen peroxide, which ensures more thorough disinfection of the sterile bag opening, reduces the growth of bacteria and other microorganisms at the sterile bag opening, and prevents bacteria and other microorganisms from entering the filling chamber 2 through the bag opening.

[0053] Working principle:

[0054] During filling, the mouth of the sterile bag is inserted into the bag entrance and fixed by the bag clamping mechanism 3. The controller controls the bag disinfection mechanism 10 to disinfect the bag mouth. After disinfection, the piston rod of the cover clamping cylinder 91 extends to drive the claw head to open and embrace the bag cover. The piston rod of the cover clamping cylinder 91 retracts, the claw clamps the bag cover and pulls up the bag cover, completing the cover opening action and the cover clamping cylinder 91 resets. The slide cylinder 11 drives the slide 1 to move to the left, so that the filling mechanism 4 is aligned with the bag opening, and the piston rod of the filling cylinder 41 extends to drive the filling head 42 to move downward to the top of the bag opening for filling. After the flow meter 45 detects that the filling amount is sufficient, it sends a signal to the controller. The controller controls the piston rod of the filling cylinder 41 to retract, and at the same time controls the piston rod of the residual liquid collecting cylinder 51 to extend, and the slide cylinder 11 drives the slide 1 to move to the right. At the same time, the residual liquid collecting tank 52 moves to the bottom of the filling head 42, and then controls the filling head 42 to move tightly with the sealing ring of the residual liquid collecting tank 52. The steam purge mechanism 7 blows out high-temperature steam to blow the filling liquid in the filling head 42 and the residual liquid collecting tank 52 along the drain pipe 62 and complete the disinfection under high-temperature steam purge. After the purge is completed, all mechanisms are reset to complete one filling.

[0055] During the entire filling process, high-temperature steam can be continuously injected into the filling bin 2 through the filling disinfection mechanism 8, so that the entire filling process is in a sterile environment and the residual filling liquid after filling can be effectively collected and discharged to prevent it from dripping onto the sterile bag or other equipment, thereby improving the safety of filling production.
