Fruit and vegetable slurries are often pasteurized uniformly, and the sterilization quality of large quantities of fruit and vegetable slurries is average; fruits and vegetables that are not completely crushed in the fruit and vegetable slurries will also sink to the bottom due to gravity, resulting in uneven filling of the fruit and vegetable slurries in each packaging bottle.

[0023] After placing the packaging bottle 60 on the top of the lifting device 20, the lifting device 20 lifts the packaging bottle 60, firstly makes the bottle mouth of the packaging bottle 60 abut against the filling assembly 50 and seals the packaging bottle 60, and in the process of further lifting the packaging bottle 60, the lifting device 20 drives the pull rod 31 to move upward, and the piston plate 32 at the bottom of the pull rod 31 generates negative pressure in the process of moving upward in the negative pressure cylinder 33, and the packaging bottle 60 is vacuumed through the negative pressure pipe 34. The present invention does not set up a special negative pressure pump and other equipment, and while the lifting device 20 lifts the packaging bottle 60, a negative pressure is generated in the negative pressure cylinder 33, and then the packaging bottle 60 is vacuumed, which simplifies the structure and saves the energy required by the negative pressure pump and other equipment.

[0024] In a preferred embodiment, a one-way solenoid valve 341 is provided on the negative pressure pipe 34. After the lifting device 20 stops lifting, the one-way solenoid valve 341 can prevent the gas in the negative pressure cylinder 33 from flowing back into the packaging bottle 60. After the filling is completed, the lifting device 20 moves downward, and the one-way solenoid valve 341 is opened at this time to discharge the gas in the negative pressure cylinder 33, waiting for the next filling.

[0025] In a preferred embodiment, the bottom area of ​​the negative pressure cylinder 33 is larger than the bottom area of ​​the packaging bottle 60; the lifting device 20 drives the packaging bottle 60 and pulls the piston plate 32 to move the same distance, and the negative pressure cylinder 33 can generate a larger negative pressure required by the packaging bottle 60.

At the same time, the fruit and vegetable slurry in a single packaging bottle 60 enters the sterilization tank 41 through the connecting pipe 411, and the electric heating layer 42 quickly heats the heating layer to sterilize the fruit and vegetable slurry according to the pasteurization method; during the heating process of the electric heating layer 42, the motor 43 drives the stirring rod 44 to rotate in the sterilization tank 41, which can not only make the fruit and vegetable slurry evenly heated, but also prevent the incompletely crushed fruits and vegetables from depositing, so that the filling is more uniform; after the disinfection is completed, the solenoid valve 53 is opened, and under the negative pressure of the packaging bottle 60, the fruit and vegetable slurry in the sterilization tank 41 enters the packaging bottle 60 to complete the filling; the lifting device 20 moves downward, so that the sealing plate 54 and the sealing flexible layer 541 are separated from the bottle mouth, the filling tube 51 is separated from the packaging bottle 60, and the one-way solenoid valve 341 is opened to exhaust the negative pressure cylinder 33 and wait for the next filling.
