Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a pre-prepared food packaging equipment. Background Technology

[0002] Pre-prepared dishes, also known as pre-cooked foods, generally refer to semi-finished or finished products made from various agricultural, livestock, poultry, and aquatic products as raw and auxiliary materials, along with seasonings and other auxiliary materials, through pre-selection, preparation, and other processes. Pre-prepared dishes usually need to be stored or transported under cold chain conditions and are intended for consumers or catering staff to simply heat or cook before consumption.

[0003] Chinese utility model patent CN221230035U discloses a broth extraction mechanism for pre-prepared food packaging, including a workbench. Support frames are welded to the middle of the left and right sides of the upper surface of the workbench, and a support ring is welded to the top of the support frame. A filling mechanism is welded inside the support ring, comprising a solid filling mechanism and a liquid filling mechanism. A packaging box is placed under the solid filling mechanism. The solid filling mechanism includes a solid bucket, a filter screen welded to the right side of the top of the solid bucket, and baffles welded to the front and rear sides of the upper surface of the filter screen. This mechanism achieves a certain degree of dry-wet separation of the pre-prepared food during packaging, and then remixes and heats the two during processing. This prevents the food from being soaked in broth for a long time, which could alter its flavor. Separating the solid and liquid components during packaging prevents liquid splashing due to solid falling and impacting during loading, and reduces the need for excessive cleaning of the workbench surface, saving manpower.

[0004] While existing technology can achieve solid-liquid separation, the solid-liquid separation device cannot accelerate the separation process, especially for some less fluid soups, which still lead to liquid splashing during actual packaging. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0032] Please see Figures 1-9 This invention provides a technical solution: a pre-prepared food packaging device, including a support frame 1 and a storage tank 2 with a feed inlet on the top. The surface of the storage tank 2 is connected to a liquid storage tank 4 via a liquid delivery pipe 3, and the liquid storage tank 4 is fixedly connected to the support frame 1. The storage tank 2 is equipped with a solid-liquid separation mechanism to separate the pre-prepared food and its broth. The storage tank 2 is divided into a dispensing area and a food placement area. After the food and broth are separated by the solid-liquid separation mechanism, the food enters the food placement area, and the broth delivery pipe 3 enters the liquid storage tank 4. The food placement area of ​​the storage tank 2 is equipped with a conveying mechanism to transport the food into a packaging box. After the food is transported into the packaging box, the liquid storage tank 4 transports the broth into the packaging box.

[0033] Specifically, the solid-liquid separation mechanism includes a filter cylinder 5 with openings at both the top and bottom. A connecting rod 6 is fixedly connected inside the filter cylinder 5, and an electric push rod 7 is fixedly connected to the surface of the connecting rod 6. A sealing cover 8 is fixedly connected to the end of the output shaft of the electric push rod 7. The surface of the sealing cover 8 is connected to the opening at the bottom of the filter cylinder 5, and the sealing cover 8 is movably sleeved on the surface of the connecting rod 6. The bottom of the filter cylinder 5 is movably connected to the inner side wall of the material distribution area of ​​the storage tank 2 through a rotating bearing. The top of the connecting rod 6 is fixedly connected to the filter cylinder 5 through a connecting frame 9. A drive motor 10 is fixedly connected to the top of the storage tank 2, and the drive motor 10 is connected to the connecting frame 9 in a transmission connection.

[0034] In this embodiment, the pre-cooked food containing broth is poured into the storage tank 2 through the opening at the top of the storage tank 2. The pre-cooked food first enters the interior of the filter cylinder 5, which can retain the food, while the broth flows out through the gaps in the filter cylinder 5 and enters the bottom of the dispensing area for temporary storage.

[0035] Specifically, the material conveying mechanism includes a screw conveyor 14, a universal coupling 15, and a transmission rod 16. A material conveying pipe 17 is fixedly connected to the outlet of the filter cylinder 5. The screw conveyor 14 is movably connected inside the material conveying pipe 17. One end of the screw conveyor 14 is fixedly connected to one end of the universal coupling 15, and the other end of the universal coupling 15 is fixedly connected to the transmission rod 16. The other end of the transmission rod 16 is connected to the first electromagnetic coupling 39 through a gearbox 18. The other end of the first electromagnetic coupling 39 is fixedly connected to the connecting rod 6. A sealing plate 19 is movably connected to the outlet of the material conveying pipe 17. The surface of the sealing plate 19 is movably connected to the drive push rod 20, and the other end of the drive push rod 20 is movably connected to the surface of the material conveying pipe 17.

[0036] In this embodiment, a spiral conveyor rod 14 and a transmission rod 16 are installed inside the food placement area of ​​the storage tank 2. When the stirring motor 22 is started, the first electromagnetic coupling 39 can be de-energized to save energy. The stirring motor 22 can rotate the rotating rod through the power rod 21 and the gearbox 18, thereby driving the spiral conveyor rod 14 to rotate through the universal coupling 15, and then squeezing the mixed raw materials into the conveying pipe 17. When the conveyor belt transports the packaging box to the outlet of the conveying pipe 17, the drive push rod 20 retracts, causing the closing plate 19 to move and open the conveying pipe 17. Then the spiral conveyor rod 14 rotates, pushing the raw materials out of the conveying pipe 17 and dropping them into the packaging box.

[0037] Specifically, the gearbox 18 is also connected to the stirring motor 22 via the power rod 21. The stirring motor 22 is fixedly connected to the surface of the storage tank 2, and the stirring blade 23 is fixedly connected to the surface of the transmission rod 16.

[0038] In this embodiment, the stirring blade 23 can cut the food when the feeding pipe 17 cannot discharge food normally. Specifically, the stirring motor 22 increases its speed, which in turn increases the speed of the stirring blade 23, thus chopping the food.

[0039] Specifically, a first electromagnet 11 is fixedly connected to the top of the connecting frame 9, the output shaft of the drive motor 10 moves through the storage tank 2 and is fixedly connected to the rotating frame 12, and an annular groove 13 is opened at the bottom of the rotating frame 12, and the surface of the first electromagnet 11 is movably connected to the inner wall of the annular groove 13.

[0040] Specifically, an electromagnetic ring 24 is fixedly connected to the surface of the rotating frame 12, and a rotating ring 25 is movably connected to the surface of the electromagnetic ring 24. The outer surface of the rotating ring 25 is movably connected to the inner wall of the filter cartridge 5 through a connecting bearing. Multiple inclined stirring rod groups 26 are fixedly connected to the bottom of the rotating ring 25. Each inclined stirring rod group 26 includes multiple inclined stirring rods. The outermost inclined stirring rod in each inclined stirring rod group 26 is movably connected to the inner wall of the distribution area of ​​the storage tank 2, and the innermost inclined stirring rod in each inclined stirring rod group 26 is movably connected to the surface of the filter cartridge 5. The bottom of all the inclined stirring rods in each inclined stirring rod group 26 is movably connected to the inner wall of the distribution area of ​​the storage tank 2. An electromagnetic leakage valve 27 is fixedly connected to the bottom of the distribution area of ​​the storage tank 2. An annular sleeve 28 is fixedly connected to the surface of the storage tank 2 at the position corresponding to the electromagnetic leakage valve 27. The annular sleeve 28 is fixedly connected to the infusion pipe 3.

[0041] In this embodiment, in order to heat the separated broth faster and more evenly, the drive motor can be started. In this case, the first electromagnet 11 does not need to be energized, that is, the rotating frame 12 does not need to drive the connecting frame 9 to rotate. Only the electromagnetic ring 24 needs to be energized to drive the rotating ring 25 to rotate, thereby enabling the rotating ring 25 to drive the multiple inclined stirring rods 26 to rotate and stir the separated broth.

[0042] Specifically, a heater 29 is fixedly connected to the outer wall of the material distribution area of ​​the storage tank 2, and an insulation ring 30 is fixedly connected to the storage tank 2 at the position corresponding to the heater 29; a steam vent 31 is opened on the top of the storage tank 2, and a steam collecting ring 32 is fixedly connected to the surface of the storage tank 2 at the position corresponding to the steam vent 31. The steam collecting ring 32 is fixedly connected to the condenser box 33 through a steam transmission pipe, and the condenser box 33 is fixedly connected to the surface of the storage tank 2.

[0043] In this embodiment, for soups with high fluidity, the rotating ring 25 drives multiple inclined stirring rods 26 to rotate, which can stir the soup. This not only facilitates soup concentration but also prevents sticking to the bottom. The water vapor generated by evaporation can enter the steam collecting ring 32 through the exhaust port 31 and then enter the condenser 33 for condensation.

[0044] Specifically, a plurality of stirring rods 34 are fixedly connected to the surface of the sealed cover 8. The connecting rod 6 includes a connecting part 601 and a transmission part 602. The connecting part 601 and the transmission part 602 are connected by a second electromagnetic coupling 35. The electric push rod 7 is fixedly connected to the surface of the connecting part 601, and the transmission part 602 is fixedly connected to the connecting frame 9.

[0045] In this embodiment, the first electromagnetic coupling 39 is energized, the stirring motor 22 drives the power rod 21 to rotate, the gearbox 18 and the first electromagnetic coupling 39 drive the connecting part 601 to rotate, which in turn drives the closed cover 8 to rotate. At the same time, the second electromagnetic coupling 35 is de-energized, the first electromagnet 11 and the electromagnetic ring 24 are energized, the drive motor 10 makes the rotating ring 25 rotate, and the soup is stirred. At the same time, the filter cylinder 5 rotates. At this time, the rotation direction of the filter cylinder 5 and the closed cover 8 can be opposite, so that the food can be stirred every time it is transported into the packaging box.

[0046] Specifically, a stirring ring 36 is fixedly connected inside the food placement area of ​​the storage tank 2, and the inner diameter of the stirring ring 36 is adapted to the outer diameter of the closed cover 8.

[0047] In this embodiment, for some pre-prepared dishes that require mixing the ingredients and broth before packaging, mixing the ingredients and broth in advance can enhance the flavor of the ingredients. In this case, the sealing cover 8 can be moved downwards by the stirring ring 36 and the electric push rod 7, forming an area with an opening at the top between the sealing cover 8 and the stirring ring 36. The pre-prepared broth and ingredients are placed into this area, and the sealing cover 8 is rotated to mix them by the stirring rod 34.

[0048] Specifically, a vacuum pump 37 is fixedly connected to the top of the liquid storage tank 4, a liquid outlet solenoid valve 38 is fixedly connected to the liquid outlet pipe of the liquid storage tank 4, and the liquid storage tank 4 is fixedly connected to the support frame 1 through a fixing rod.

[0049] In this implementation, the food enters the packaging box under the action of the conveyor belt. Then the packaging box moves to the bottom of the liquid storage tank 4, the liquid discharge solenoid valve 38 opens, and the soup flows out. Then the air pump 37 draws air to block the soup from flowing out. At the same time, the liquid discharge solenoid valve 38 is turned off to prevent the soup from dripping.

[0050] Pre-packaged dishes that require tight packaging can be added to storage tank 2. Pre-packaged dishes are made from one or more edible agricultural products and their products as raw materials, with or without the use of seasonings and other auxiliary materials, without the addition of preservatives, and are produced through industrial pre-processing such as stirring, marinating, rolling, shaping, frying, deep-frying, roasting, boiling, steaming, etc. With or without seasoning packets, they meet the storage, transportation and sales conditions indicated on the product label and can be eaten after heating or cooking.

[0051] If no seasonings or other auxiliary materials are used, and the raw materials, which have undergone industrial pre-processing, are directly packaged using this equipment, the raw materials can be placed directly into the tank from the opening at the top of the storage tank 2, and then the opening can be sealed. In this case, solid-liquid separation is not required. However, if multiple raw materials are placed and mixing is required, the drive motor 10 can be started. The drive motor 10 drives the rotating frame 12 to rotate, and at the same time, the first electromagnet 11 on the connecting frame 9 is energized. Thus, the first electromagnet 11 can fix the connecting frame 9 to the rotating frame 12, allowing the connecting frame 9 and the rotating frame 12 to rotate synchronously. The connecting frame 9 drives the filter cartridge 5 to rotate.

[0052] The second electromagnetic coupling 35 is not energized, while the first electromagnetic coupling 39 is energized. Simultaneously, the stirring motor 22 starts. The stirring motor 22, via the power rod 21 and gearbox 18, allows the connecting part 601 of the connecting rod 6 to rotate. The connecting part 601, through the electric push rod 7, drives the closed cover 8 to rotate, thereby rotating the stirring rod 34 and mixing the various raw materials in the filter cylinder 5. After mixing for a period of time, under the action of the electric push rod 7, the closed cover 8 can move downwards, thus disengaging from the filter cylinder 5, allowing the mixed raw materials to fall into the food placement area of ​​the storage tank 2.

[0053] Inside the food placement area of ​​storage tank 2, a spiral conveyor rod 14 and a transmission rod 16 are installed. When the stirring motor 22 is started, the first electromagnetic coupling 39 can be de-energized to save energy. The stirring motor 22 can rotate the rotating rod through the power rod 21 and gearbox 18, thereby driving the spiral conveyor rod 14 to rotate through the universal coupling 15, thus squeezing the mixed raw materials into the conveying pipe 17. When the conveyor belt transports the packaging box to the outlet of the conveying pipe 17, the drive push rod 20 retracts, causing the closing plate 19 to move and open the conveying pipe 17. Then, the spiral conveyor rod 14 rotates, pushing the raw materials out of the conveying pipe 17 and dropping them into the packaging box.

[0054] For some pre-cooked dishes containing broth, if the pre-cooked dishes are directly transported into the packaging box through the aforementioned screw conveyor rod 14 and transmission rod 16, the dishes in the pre-cooked dishes may cause the broth to splash and result in waste. Therefore, it is advisable to consider separating the solid and liquid components of the pre-cooked dishes, then placing the dishes into the packaging box first, and then adding the broth to them.

[0055] Similarly, the pre-cooked food containing broth is poured into the storage tank 2 through the opening at the top of the storage tank 2. The pre-cooked food will first enter the interior of the filter cylinder 5, which can retain the food, while the broth will flow out through the gaps in the filter cylinder 5 and enter the bottom of the dispensing area for temporary storage.

[0056] To prevent pre-cooked food from spoiling, it is usually stored at low temperatures after preparation. However, in this case, some of the broth may solidify or become less fluid. If this broth is not filtered, it will melt and splatter during subsequent packaging due to the rising temperature. Therefore, during the solid-liquid separation of pre-cooked food, heating can be selected depending on the type of pre-cooked food. Specifically, heater 29 can be used to heat the separated broth, raising the temperature inside the storage tank 2 through heat transfer, thereby melting the remaining broth and facilitating separation.

[0057] In order to heat the separated soup faster and more evenly, the drive motor can be started. In this case, the first electromagnet 11 does not need to be energized, that is, the rotating frame 12 does not need to drive the connecting frame 9 to rotate. Only the electromagnetic ring 24 needs to be energized to drive the rotating ring 25 to rotate, thereby enabling the rotating ring 25 to drive the multiple inclined stirring rods 26 to rotate and stir the separated soup.

[0058] In addition, to accelerate the melting and separation of the broth, the ingredients in the filter cylinder 5 can be stirred. This can be achieved by driving motor 10. The stirring process is similar to the mixing process of multiple ingredients described above. The broth, when heated and stirred, becomes more fluid, which speeds up the separation process. After heating for a period of time, stirring can be stopped. At this time, the first electromagnetic coupling 39 can be de-energized, while the second electromagnetic coupling 35 is energized. Simultaneously, the first electromagnet 11 is energized, and the driving motor 10 rotates, causing the stirring ring 36 and the connecting frame 9 to rotate simultaneously. Gradually increasing the rotation speed allows the broth in the filter cylinder 5 to be thrown out by centrifugal force, accelerating the separation, which is especially suitable for broths with high fluidity.

[0059] Of course, for broths with high fluidity, heater 29 can be left unactivated. However, broths with high fluidity usually contain a lot of water. After packaging, if the food is soaked in broth with high water content, it will result in poor taste. Therefore, broths with high fluidity can be heated by heater 29 to concentrate the broth. In this case, rotating ring 25 drives multiple inclined stirring rods 26 to rotate, which can stir the broth. This not only facilitates the concentration of the broth but also prevents it from sticking to the bottom. The water vapor generated by evaporation can enter the steam collecting ring 32 through the exhaust port 31 and then enter the condenser 33 for condensation.

[0060] After the broth is separated, the electromagnetic leakage valve 27 opens, and the broth flows through the annular sleeve 28 into the infusion pipe 3, and then into the storage tank 4. The sealing cover 8 moves downward, and the dish enters the dish placement area. Under the action of the conveyor belt, the dish enters the packaging box, and then the packaging box moves to the bottom of the storage tank 4. The discharge electromagnetic valve 38 opens, and the broth flows out. Then, the air pump 37 draws air to block the flow of broth, and at the same time, the discharge electromagnetic valve 38 closes to prevent broth from dripping.

[0061] When new pre-cooked food requiring solid-liquid separation is added to the distribution area of ​​storage tank 2, the pre-cooked food undergoing solid-liquid separation can be indirectly stirred while being transported to the packaging box. Specifically, when the first electromagnetic coupling 39 is energized, the stirring motor 22 drives the power rod 21 to rotate, the gearbox 18 and the first electromagnetic coupling 39 drive the connecting part 601 to rotate, which in turn drives the closed cover 8 to rotate. At the same time, the second electromagnetic coupling 35 is de-energized, the first electromagnet 11 and the electromagnetic ring 24 are energized, and the drive motor 10 makes the rotating ring 25 rotate, stirring the soup. At the same time, the filter cylinder 5 rotates. At this time, the rotation directions of the filter cylinder 5 and the closed cover 8 can be opposite, so that the food can be stirred every time it is transported to the packaging box.

[0062] For some pre-cooked dishes that require mixing ingredients and broth before packaging, pre-mixing the ingredients and broth can enhance the flavor. In this case, the stirring ring 36 and the electric push rod 7 can be used to move the closed cover 8 downwards, forming an area with an opening at the top between the closed cover 8 and the stirring ring 36. The pre-prepared broth and ingredients are placed into this area, and the rotation of the closed cover 8, along with the stirring rod 34, mixes them together. Afterwards, the closed cover 8 moves upwards, causing the pre-cooked dish to separate from the solids. This not only prevents splashing during packaging but also ensures that the ingredients are mixed with the broth beforehand, facilitating subsequent marinating and enhancing the flavor.

[0063] Finally, when cleaning the storage tank 2 is required, cleaning fluid can be added to it. By rotating the rotating ring 25 in the opposite direction to the rotation of the closed cover 8, the cleaning fluid can be used to flush the various structures, achieving effective cleaning.
