[0032] See also Figure 1-Figure 9 The embodiment of the present invention provides a technical solution: a pre-prepared meal packaging device, comprising a support frame 1 and a material storage tank 2 with a material feeding port on the top, the surface of the material storage tank 2 is connected to a liquid storage tank 4 through an infusion pipe 3, and the liquid storage tank 4 is fixedly connected to the support frame 1; a solid-liquid separation mechanism is arranged inside the material storage tank 2, and the solid-liquid separation mechanism is used to separate the dishes and soup of the pre-prepared dishes, and the interior of the material storage tank 2 is divided into a material separation area and a dish placement area, and the dishes and soup of the pre-prepared dishes are separated by the solid-liquid separation mechanism, and the dishes enter the dish placement area, and the soup infusion pipe 3 enters the liquid storage tank 4; a feeding mechanism is arranged in the dish placement area of ​​the material storage tank 2, which is used to transport the dishes to the packaging box, and after the dishes are transported to the packaging box, the liquid storage tank 4 transports the soup to the packaging box.

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

[0034] In this embodiment, the pre-prepared dish containing soup is poured into the storage tank 2 through the opening at the top of the storage tank 2. The pre-prepared dish will first enter the interior of the filter cartridge 5. The filter cartridge 5 can retain the dish, while the soup will flow out through the gap on the filter cartridge 5 and enter the bottom of the distribution area for temporary storage.

[0035] Specifically, the feeding mechanism includes a spiral conveying rod 14, a universal coupling 15 and a transmission rod 16. A feeding pipe 17 is fixedly connected to the discharge port of the filter cartridge 5. The spiral conveying rod 14 is movably connected to the inside of the feeding pipe 17.

[0036] In this embodiment, a spiral conveying rod 14 and a transmission rod 16 are arranged inside the dish placement area of ​​the storage tank 2. When the stirring motor 22 is started, the first electromagnetic coupling 39 can be powered off to save electric energy. The stirring motor 22 can realize the rotation of the rotating rod through the power rod 21 and the gear box 18, thereby driving the spiral conveying rod 14 to rotate through the universal coupling 15, and then squeezing the mixed raw materials into the feeding pipe 17. When the conveyor belt transports the packaging box to the outlet of the feeding pipe 17, the driving push rod 20 is retracted to move the closing plate 19 to open the feeding pipe 17, and then the spiral conveying rod 14 rotates to push the raw materials out of the feeding pipe 17 and drop them into the packaging box.

[0037] Specifically, the gear box 18 is also connected to the stirring motor 22 through the power rod 21 . The stirring motor 22 is fixedly connected to the surface of the storage tank 2 . The surface of the transmission rod 16 is fixedly connected with a stirring blade 23 .

[0038] In this embodiment, the stirring blade 23 can cut the food when the feeding pipe 17 cannot discharge the food normally. Specifically, the stirring motor 22 increases the speed, so that the stirring blade 23 increases the speed and cuts the food.

[0039] Specifically, a first electromagnet 11 is fixedly connected to the top of the connecting frame 9, the output shaft of the driving motor 10 movably passes through the storage tank 2 and is fixedly connected to the rotating frame 12, an annular groove 13 is provided 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, and the outer surface of the rotating ring 25 is movably connected to the inner wall of the filter cartridge 5 through a connecting bearing; a plurality of inclined stirring rod groups 26 are fixedly connected to the bottom of the rotating ring 25, and each inclined stirring rod group 26 includes a plurality of inclined stirring rods, the outermost inclined stirring rod in each inclined stirring rod group 26 is movably connected to the inner wall of the distributing area of ​​the storage tank 2, the innermost inclined stirring rod in each inclined stirring rod group 26 is movably connected to the surface of the filter cartridge 5, and the bottoms of all the inclined stirring rods in each inclined stirring rod group 26 are movably connected to the inner wall of the distributing area of ​​the storage tank 2; an electromagnetic leakage valve 27 is fixedly connected to the bottom of the distributing area of ​​the storage tank 2, and an annular sleeve 28 is fixedly connected to the surface of the storage tank 2 corresponding to the position of the electromagnetic leakage valve 27, and the annular sleeve 28 is fixedly connected to the infusion tube 3.

[0041] In this embodiment, in order to make the separated soup heated 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 is not required to drive the connecting frame 9 to rotate. It is only necessary to energize the electromagnetic ring 24 to drive the rotating ring 25 to rotate, so that the rotating ring 25 drives the multiple inclined stirring rod groups 26 to rotate and stir the separated soup.

[0042] Specifically, a heater 29 is fixedly connected to the outer wall of the material distribution area corresponding to the storage tank 2, and an insulation ring sleeve 30 is fixedly connected to the position of the storage tank 2 corresponding to the heater 29; a steam exhaust port 31 is opened on the top of the storage tank 2, and a steam collecting ring sleeve 32 is fixedly connected to the surface of the storage tank 2 corresponding to the steam exhaust port 31, and the steam collecting ring sleeve 32 is fixedly connected to the condensation box 33 through a steam transmission pipe, and the condensation 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 the multiple inclined stirring rod groups 26 to rotate, so that the soup can be stirred, which not only facilitates the concentration of the soup, but also prevents it from sticking to the bottom. The water vapor generated by evaporation can enter the steam collecting ring sleeve 32 through the exhaust port 31, and then enter the condensation box 33 for condensation.

[0044] Specifically, a plurality of stirring rods 34 are fixedly connected to the surface of the closed 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 via 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 gear box 18 and the first electromagnetic coupling 39 drive the connecting part 601 to rotate, and then drives the closing cover 8 to rotate, and at the same time the second electromagnetic coupling 35 is de-energized, the first electromagnet 11 and the electromagnetic ring 24 are energized, the driving motor 10 rotates the rotating ring 25 to stir the soup, and at the same time the filter cartridge 5 rotates. At this time, the rotation directions of the filter cartridge 5 and the closing cover 8 can be opposite, so that the dishes can be stirred every time they are transported to 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 matched with the outer diameter of the sealing cover 8 .

[0047] In this embodiment, for some pre-prepared dishes that need to mix the raw materials and the soup before packaging, mixing the raw materials and the soup in advance can increase the flavor of the raw materials. In this case, the electric push rod 7 can move the sealing cover 8 downward with the help of the stirring ring 36, and an area with an opening on the top is formed between the sealing cover 8 and the stirring ring 36. The pre-prepared soup and raw materials are placed in it, and the sealing cover 8 is rotated and stirred and mixed by the stirring rod 34.

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

[0049] In this embodiment, under the action of the conveyor belt, the dishes enter the packaging box, and then the packaging box moves to the bottom of the liquid storage tank 4, the liquid outlet solenoid valve 38 opens, and the soup flows out. Then the vacuum pump 37 draws air to block the outflow of the soup. At the same time, the liquid outlet solenoid valve 38 is closed to prevent the soup from dripping.

[0050] Pre-prepared dishes that need to be tightly packaged can be added to the storage tank 2. The pre-prepared dishes are made from one or more edible agricultural products and their products as raw materials, with or without seasonings and other auxiliary materials, without adding preservatives, and are made through industrial pre-processing such as stirring, pickling, tumbling, kneading, shaping, stir-frying, deep-frying, baking, boiling, steaming, etc., with or without seasoning packets, and meet the storage, transportation and sales conditions indicated on the product label, and are pre-packaged dishes that can be eaten only after heating or cooking.

[0051] If seasonings and other auxiliary materials are not used, and the raw materials formed by industrial pre-processing are directly packaged through this equipment, the raw materials can be directly placed into the tank from the opening on the top of the storage tank 2, and then the opening is closed. At this time, solid-liquid separation is not required. However, if multiple raw materials are placed and need to be stirred and mixed, the drive motor 10 can be started, and the drive motor 10 drives the rotating frame 12 to rotate. At the same time, the first electromagnet 11 on the connecting frame 9 is energized, so that the connecting frame 9 and the rotating frame 12 can be fixed through the first electromagnet 11, and the connecting frame 9 and the rotating frame 12 can be rotated synchronously, and the connecting frame 9 drives the filter cartridge 5 to rotate.

[0052] The second electromagnetic coupling 35 is not energized, the first electromagnetic coupling 39 is energized, and the stirring motor 22 is started at the same time. The stirring motor 22 can rotate the connecting portion 601 of the connecting rod 6 through the power rod 21 and the gear box 18. The connecting portion 601 drives the closing cover 8 to rotate through the electric push rod 7, thereby realizing the rotation of the stirring rod 34 to mix the various raw materials in the filter cartridge 5. After stirring and mixing for a period of time, under the action of the electric push rod 7, the closing cover 8 can move downward, thereby breaking contact with the filter cartridge 5, and the mixed raw materials can fall into the dish placement area of ​​the storage tank 2.

[0053] A screw conveying rod 14 and a transmission rod 16 are arranged inside the food placement area of ​​the storage tank 2. When the stirring motor 22 is started, the first electromagnetic coupling 39 can be powered off to save electric energy. The stirring motor 22 can realize the rotation of the rotating rod through the power rod 21 and the gear box 18, thereby driving the screw conveying rod 14 to rotate through the universal coupling 15, and then squeezing the mixed raw materials into the feeding pipe 17. When the conveyor belt transports the packaging box to the outlet of the feeding pipe 17, the driving push rod 20 is retracted to move the closing plate 19 to open the feeding pipe 17, and then the screw conveying rod 14 rotates to push the raw materials out of the feeding pipe 17 and drop them into the packaging box.

[0054] As for some pre-prepared dishes containing soup, if the pre-prepared dishes are directly transported to the packaging box through the spiral conveying rod 14 and the transmission rod 16, the dishes in the pre-prepared dishes may cause the soup to splash and cause waste. Therefore, it is possible to consider separating the solid and liquid of the pre-prepared dishes, and then placing the dishes in the packaging box before adding the soup.

[0055] Similarly, the pre-prepared dish containing soup is poured into the storage tank 2 through the opening at the top of the storage tank 2. The pre-prepared dish will first enter the interior of the filter cartridge 5, which can retain the dish, while the soup will flow out through the gap on the filter cartridge 5 and enter the bottom of the distribution area for temporary storage.

[0056] In order to prevent the pre-prepared food from spoiling, the pre-prepared food is usually stored at low temperature after being prepared. In this case, the soup of some pre-prepared food will solidify or have poor fluidity. If this part of the soup is not filtered, the soup will melt due to the temperature rise in the subsequent packaging process, causing splashing. Therefore, when the pre-prepared food is separated into solid and liquid, it can be selected whether to heat it according to the type of the pre-prepared food, that is, the separated part of the soup can be heated by the heater 29, and the temperature inside the storage tank 2 can be increased by heat transfer, so that the unseparated soup can be melted, which is convenient for separation.

[0057] In order to heat the separated soup faster and 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 is not required to drive the connecting frame 9 to rotate. It is only necessary to energize the electromagnetic ring 24 to drive the rotating ring 25 to rotate, so that the rotating ring 25 drives the multiple inclined stirring rod groups 26 to rotate and stir the separated soup.

[0058] In addition, in order to melt and separate the soup faster, the dishes in the filter cartridge 5 can be stirred. This can be achieved specifically by driving the motor 10. The stirring process is similar to the process of mixing multiple raw materials mentioned above. The soup is heated and stirred, which increases its fluidity and speeds up the separation process. After heating for a period of time, the stirring can be stopped. At this time, the first electromagnetic coupling 39 can be powered off, while the second electromagnetic coupling 35 is powered on. At the same time, the first electromagnet 11 is powered on. When the driving motor 10 rotates, the stirring ring 36 and the connecting frame 9 can be rotated at the same time. By gradually increasing the rotation speed, the soup in the filter cartridge 5 can be thrown out by the action of centrifugal force, which speeds up the separation, and is particularly suitable for soups with greater fluidity.

[0059] Of course, for soup with high fluidity, the heater 29 may not be started, but soup with high fluidity usually contains more water. After packaging, the dishes are soaked in the soup with high water content, which will cause the taste of the dishes to be poor. Therefore, the soup with high fluidity can be heated by the heater 29 to concentrate the soup. In this case, the rotating ring 25 drives the plurality of inclined stirring rod groups 26 to rotate, so that the soup can be stirred, which is not only convenient for soup concentration, but also can prevent the soup from sticking to the bottom. The water vapor generated by evaporation can enter the steam collecting ring sleeve 32 through the exhaust port 31, and then enter the condensation box 33 for condensation.

[0060] When the soup is separated, the electromagnetic leakage valve 27 opens, and the soup flows into the infusion tube 3 through the annular sleeve 28, and then enters the liquid storage tank 4. The closing cover 8 moves downward, and the dishes enter the dish placement area. Under the action of the conveyor belt, the dishes enter the packaging box, and then the packaging box moves to the bottom of the liquid storage tank 4, the liquid outlet electromagnetic valve 38 opens, and the soup flows out, and then the vacuum pump 37 pumps air to block the soup from flowing out, and at the same time the liquid outlet electromagnetic valve 38 is closed to prevent the soup from dripping.

[0061] When new pre-prepared dishes that need to be separated from solids and liquids are added to the material distribution area of ​​the storage tank 2, the pre-prepared dishes that are undergoing solid-liquid separation can be indirectly stirred while the dishes are being transported to the packaging box. Specifically, the first electromagnetic coupling 39 is energized, the stirring motor 22 drives the power rod 21 to rotate, the gear box 18 and the first electromagnetic coupling 39 drive the connecting part 601 to rotate, and then drive the closed cover 8 to rotate, while the second electromagnetic coupling 35 is powered off, the first electromagnet 11 and the electromagnetic ring 24 are energized, the driving motor 10 rotates the rotating ring 25 to stir the soup, and the filter cartridge 5 rotates at the same time. At this time, the rotation directions of the filter cartridge 5 and the closed cover 8 can be opposite, so that the dishes can be stirred every time the dishes are transported to the packaging box.

[0062] For some pre-prepared dishes that need to mix the raw materials and soup before packaging, mixing the raw materials and soup in advance can increase the flavor of the raw materials. In this case, the electric push rod 7 can move the closed cover 8 downward with the help of the stirring ring 36, and an area with an opening on the top is formed between the closed cover 8 and the stirring ring 36. The pre-prepared soup and raw materials are placed in it, and the closed cover 8 is rotated and stirred and mixed by the stirring rod 34. After that, the closed cover 8 moves upward, and the pre-prepared dish is separated into solid and liquid. In this way, it can not only prevent splashing when packaging, but also allow the raw materials to be mixed with the soup in advance, which is convenient for subsequent pickling after packaging and increases the flavor.

[0063] Finally, when the storage tank 2 needs to be cleaned, cleaning liquid can be added to the storage tank 2. By making the rotating ring 25 rotate in the opposite direction to the closing cover 8, the cleaning liquid can flush each structure and achieve effective cleaning.
