Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a sterilizing device for vacuum packaging of pre-prepared dishes. Background Art

[0002] The sterilization device for vacuum packaging of pre-prepared food is a device specially used for high-temperature sterilization of vacuum-packed food. It uses high-temperature water flow in a closed kettle to heat the vacuum-sealed food to kill microorganisms and extend the shelf life. Existing sterilization devices for vacuum packaging of pre-prepared dishes usually adopt an integrated frame. The traditional integrated frame design usually lays all packaging bags uniformly on the rack and shares the same water flow and steam space. If the packaging bag is broken, the liquid in the packaging bag will spread to other packaging bags through the water flow, causing overall group contamination. In the traditional fixed rack design, the packaging bag always remains stationary, and the spray device can only spray the packaging bag from a fixed angle. The surface of the packaging bag is prone to uneven heat distribution, resulting in unsatisfactory sterilization effect. In order to solve the above problems, the inventor proposed a sterilization device for vacuum packaging of pre-prepared dishes. Summary of the invention

[0013] When the partition compartment rotates, the guide rail and the vacuum packaging bag move back and forth along the slide groove, so that the sprayed hot water acts evenly on each side of the vacuum packaging bag. Compared with the traditional fixed storage rack design adopted in the prior art, the vacuum packaging bag always remains stationary, and the spray device can only spray to the packaging bag from a fixed angle, which easily causes uneven heat distribution. The present device allows the vacuum packaging bag to move back and forth along the slide groove, so that water or steam evenly bypasses each side of each vacuum packaging bag, reducing the phenomenon of insufficient heating in local areas, improving the uniformity of heat conduction, and thus improving the consistency of sterilization. The rotation allows each bag surface to be fully sprayed without being restricted by dead angles.

[0014] By closing the electromagnet to control the opening of the bottom plate, the moisture on the vacuum packaging bag is quickly discharged after the bottom plate is opened. Compared with the manual drying or centrifuge draining method in the prior art, the device uses the opening and closing of the bottom plate controlled by the electromagnet and combines it with rotation to drain the water, thereby realizing automatic drainage. Not only is the speed faster, but the drying effect is more uniform, avoiding the tedious steps of manual drying with the help of tools, reducing human interference, avoiding the steps of taking out the vacuum packaging bag and then putting it into the centrifuge, and simplifying the sterilization process.

[0023] Further, such as Fig. 9 and Fig.10 As shown, the rotating assembly also includes a cavity column 412 fixedly connected to the storage table 31, the inner cavity of the cavity column 412 is fixedly connected to a limiting plate 413, a round cap rod 414 is slidably connected inside the limiting plate 413, the limiting plate 413 is used to limit the horizontal movement range of the round cap rod 414, the outer surface of the round cap rod 414 is fixedly connected to a fixing ring 415, the side of the fixing ring 415 away from the limiting plate 413 is fixedly connected to a spring 416, the outer surface of the round cap rod 414 is fixedly connected to a fixing ring 417, the fixing ring 417 is used to limit the horizontal movement range of the round cap rod 414, the outer surface of the round cap rod 414 is slidably connected to a reset ring 418, and the reset ring 418 is located on the side of the fixing ring 417 away from the spring 416.

[0024] Further, such as Fig.10As shown, the round cap rod 414, the fixing ring 1 415, the fixing ring 2 417 are slidably connected to the inner cavity of the cavity column 412, the end of the spring 2 416 away from the fixing ring 1 415 is fixedly connected to the inner cavity of the cavity column 412, and the side of the fixing ring 2 417 close to the reset ring 418 is magnetic, and the fixing ring 2 417 adsorbs the reset ring 418.

[0025] When the device is spraying and sterilizing, the separation chamber 32 is rotated, and the detailed steps are as follows: Before spray sterilization, the staff pulls out the storage table 31, and opens the hinged doors of the three compartments 32, respectively, and pulls the support plate 37 out of the compartment 32 through the guide rail 35, and places the vacuum packaging bags of the pre-prepared dishes on the surface of the support plate 37, and uses the fixed partition column 38 to separate each vacuum packaging bag from each other. After placing the vacuum packaging bags, the support plate 37 is pushed back to the initial position along the guide rail 35, and the hinged doors of the three compartments 32 are closed respectively; After closing the hinged doors of the three compartments 32, the staff pushes the storage table 31 to move horizontally toward the side close to the gear rotating disk 41. When the storage table 31 can no longer be pushed, the staff stops pushing. At this time, the water inlet pipe 42 has been inserted into the water inlet 39, and the water outlet pipe 43 has been inserted into the water outlet 310. Then, the staff closes the hinged door of the sterilizing kettle 1 to seal the interior of the sterilizing kettle 1. When the staff pushes the storage platform 31 to move horizontally toward the side close to the gear rotating disk 41, the cavity column 412 moves horizontally with the storage platform 31, so that the round cap rod 414 gradually enters the slot 44. When the round cap rod 414 enters the slot 44, the outer surface of the round cap on the side of the round cap rod 414 close to the gear rotating disk 41 contacts the inclined surface of the trapezoidal rod 410. As the round cap rod 414 continues to move horizontally, the round cap on the side of the round cap rod 414 close to the gear rotating disk 41 squeezes the trapezoidal rod 410, so that the trapezoidal rod 410 moves vertically upward along the limit plate 49, and the spring 411 is continuously compressed. When the round caps on the side of the round cap rod 414 close to the gear rotating disk 41 all pass through When the trapezoidal rod 410 is in the state of being pressed, the trapezoidal rod 410 does not contact the outer surface of the round cap on the round cap rod 414 close to the gear rotating disk 41, so that the trapezoidal rod 410 is free from the restriction of the round cap on the round cap rod 414 close to the gear rotating disk 41. At this time, the spring 1 411 changes from the compressed state to the initial state, pushing the trapezoidal rod 410 to move vertically downward along the inner cavity of the groove 48. When the spring 1 411 changes to the initial state, the trapezoidal rod 410 is also in the initial position. At this time, the vertical surface of the trapezoidal rod 410 contacts the bottom surface of the round cap on the round cap rod 414 close to the gear rotating disk 41, and the storage table 31 cannot be pushed further. In this way, the trapezoidal rod 410 is used to fix the storage table 31, so that the storage table 31 cannot be moved horizontally. After the fixing of the storage table 31 is completed, the staff starts the circulation pump in the heating water tank, so that the hot water in the heating water tank enters the nozzles 33 in the three compartments 32 through the main water inlet pipe 46, the branch water inlet pipes 42 and the water inlet 39 respectively, and then the hot water is sprayed out by the nozzles 33 to spray and sterilize the outer surface of the vacuum packaging bag. The sprayed hot water passes through the cover plate 36 and the support plate 37 to reach the bottom surface of the inner cavity of the compartment 32, and then flows into the heating water tank through the water outlet 310, the branch water outlet pipes 43 and the main water outlet pipe 47. The water source in the heating water tank is continuously circulated by the circulation pump; After the staff starts the circulation pump in the heating water tank, the servo motor is started, so that the servo motor drives the gear drive disk 45 to rotate, and further the gear drive disk 45 drives the gear rotating disk 41, the storage table 31 and the partition chamber 32 to rotate. During the rotation of the partition chamber 32, due to the effect of gravity, the guide rail 35, the cover plate 36 and the support plate 37 in the partition chamber 32 move back and forth along the slide groove 34. During the reciprocating movement of the guide rail 35 along the slide groove 34, each surface of the vacuum packaging bag on the support plate 37 can be sprayed with hot water for sterilization. When the sterilization is completed, the staff stops the servo motor through the controller; By setting up three independent separation chambers 32, compared with the traditional integrated frame design adopted in the prior art, usually all the vacuum packaging bags are uniformly laid flat on the storage rack to share the same water flow and steam space. If the vacuum packaging bag is not completely sealed, the vacuum packaging bag will be broken during the sterilization process, causing the liquid in the bag to spread to other packaging bags through the water flow during the spray sterilization process, resulting in overall group contamination. The present device is provided with three layers of independent separation chambers 32. Even if a bag is damaged, the leaked objects can only stay in the independent layer and are not easy to enter other product layers, thereby protecting the integrity and safety of the entire batch.

[0026] When the partition chamber 32 rotates, the guide rail 35 and the vacuum packaging bag move back and forth along the slide groove 34, so that the sprayed hot water acts evenly on each side of the vacuum packaging bag. Compared with the traditional fixed storage rack design adopted in the prior art, the vacuum packaging bag always remains in a stationary state, and the spray device can only spray to the packaging bag from a fixed angle, which easily causes uneven heat distribution. The present device allows the vacuum packaging bag to move back and forth along the slide groove 34, so that the water flow or steam evenly bypasses each side of each vacuum packaging bag, reducing the phenomenon of insufficient heating in local areas, improving the uniformity of heat conduction, and thus improving the consistency of sterilization. The rotation allows each bag surface to be fully sprayed without being restricted by dead angles.

[0027] Embodiment 2: Further, as Fig.11 and Fig.12 As shown, a drainage assembly is arranged above the support plate 2, and the drainage assembly includes a rotating shaft 51 fixedly connected to the bottom surface of each partition chamber 32, and a bottom plate 52 is rotatably connected to the rotating shaft 51, and the bottom plate 52 is located below the partition chamber 32. Two springs 53 are fixedly connected to the upper surface of each bottom plate 52, and no less than six springs 53 are arranged. A drainage hole 54 is opened on the bottom surface of the inner cavity of the partition chamber 32, and an electromagnet 55 is fixedly connected to the bottom surface of the partition chamber 32.

[0028] Further, such as Fig.12 As shown, a sealing gasket is provided on one side of the bottom plate 52 close to the partition chamber 32 , one end of the spring 53 away from the bottom plate 52 is fixedly connected to the partition chamber 32 , and the electromagnet 55 adsorbs the bottom plate 52 .

[0029] After completing the sterilization, the device can be rotated to drain water. The detailed steps are as follows: After the spray sterilization is completed, the staff uses the controller to change the electromagnet 55 from the open state to the closed state, so that the electromagnet 55 loses the adsorption force on the bottom plate 52, and further causes the bottom plate 52 to rotate in the direction away from the side of the partition chamber 32 with the rotation connection with the rotating shaft 51 as the axis, until the bottom plate 52 can no longer rotate, at which time the bottom of the partition chamber 32 is in the open state, and the spring three 53 is in the stretched state; When the bottom of the partition chamber 32 is in an open state, the staff uses the controller to make the output shaft of the servo motor rotate again, thereby making the partition chamber 32 rotate again. During the rotation of the partition chamber 32, the centrifugal force generated by the rotation is used to throw out the water remaining on the surface of the vacuum packaging bag, so that the remaining water is separated from the vacuum packaging bag and leaves the interior of the partition chamber 32, thereby completing the drainage; When the draining work is completed, the staff opens the hinged door of the outer wall of the sterilizing kettle 1 and pushes the round cap rod 414, so that the round cap rod 414 moves horizontally along the inner cavity of the cavity column 412 in a direction away from the side of the second limit plate 413 until the round cap rod 414 can no longer be pushed, and then stops pushing the round cap rod 414; When the round cap rod 414 is pushed, the side of the reset ring 418 away from the second fixing ring 417 squeezes the trapezoidal rod 410, so that the trapezoidal rod 410 moves vertically upward along the inner cavity of the groove 48. As the round cap rod 414 continues to move, the trapezoidal rod 410 is located in the middle position of the reset ring 418. When the round cap rod 414 can no longer be pushed, the trapezoidal rod 410 moves to the surface of the reset ring 418 close to the second fixing ring 417. At this time, the spring 1 411 applies downward pressure, so that the bottom of the trapezoidal rod 410 is located between the reset ring 418 and the second fixing ring 417. When the round cap rod 414 can no longer be pushed, the staff member lets go and, with the help of the rebound of the second spring 416, drives the round cap rod 414 to return to the initial position horizontally along the inner cavity of the cavity column 412. During the process of the round cap rod 414 returning to the initial position, the bottom of the trapezoidal rod 410 is always stuck with the reset ring 418, so that the reset ring 418 and the trapezoidal rod 410 remain relatively stationary until the reset ring 418 contacts the side away from the fixed ring 417 and enters the bottom of the round cap on the side of the round cap rod 414 close to the gear rotating disk 41. As the round cap rod 414 moves horizontally, the reset ring 418 and the round cap squeeze the trapezoidal rod 410, so that the trapezoidal rod 410 moves vertically upward. When the bottom of the trapezoidal rod 410 is located on the outer surface of the round cap, the round cap rod 414 has been freed from the restriction of the trapezoidal rod 410, and the trapezoidal rod 410 and the round cap rod 414 have returned to the initial position. Then the staff can open the hinged doors on the outer wall of the nozzle 33, pull out the support plate 37, and take out the sterilized vacuum packaging bags so as to carry out the sterilization treatment of the next batch of vacuum packaging bags; By closing the electromagnet 55 to control the opening of the bottom plate 52, the water on the vacuum packaging bag is quickly discharged after the bottom plate 52 is opened. Compared with the manual drying or centrifuge draining method in the prior art, the device uses the opening and closing of the bottom plate 52 controlled by the electromagnet 55 combined with rotation to drain water, thereby realizing automatic drainage. Not only is the speed faster, but the drying effect is more uniform, avoiding the tedious steps of manual drying with the help of tools, reducing human interference, avoiding the steps of taking out the vacuum packaging bag and then putting it into the centrifuge, and simplifying the sterilization process.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
