[0019] Embodiment 1

[0020] See also Figure 1-4 The present invention provides a frozen meat steam thawing device based on a vacuum environment, the thawing device comprises a thawing box 1, a vacuum pumping component 7, a driving component 8 and a steam supply component 9, a sealing cover 2 is movably installed on the top of the thawing box 1 through a hinge, a rubber pad is fixedly connected to the bottom of the sealing cover 2, a discharge funnel 3 is fixedly installed on the bottom of the thawing box 1, a discharge valve is fixedly installed on the outside of the discharge funnel 3, a rotating pipe 4 is movably sleeved on the middle part of the side of the thawing box 1, a flow pipe 5 is fixedly connected to the outside of the rotating pipe 4, and the flow pipe 5 The inner side of the rotary tube 4 is fixedly connected with a branch pipe 6, the outer sides of the rotary tube 4 and the branch pipe 6 are provided with through holes, the inner side of the rotary tube 4 is fixedly sleeved with a stopper 10, the vacuum pumping assembly 7 comprises an exhaust pipe 71 and a No. 1 connecting pipe 72, the exhaust pipe 71 is movably sleeved inside one end of the rotary tube 4, the No. 1 connecting pipe 72 is fixedly connected to the outer side of the rotary tube 4, the bottom end of the exhaust pipe 71 is fixedly connected with an exhaust pump 73, and an exhaust valve is fixedly installed on the outer side of the exhaust pipe 71, and an exhaust hood 74 is fixedly installed on one side of the No. 1 connecting pipe 72; In this embodiment, the vacuum pump 73 and the vacuum valve are first turned on, and the vacuum pipe 71 is used to evacuate air. At this time, negative pressure will be generated inside the circulation pipe 5 and the No. 1 connecting pipe 72, and suction will be generated at the through holes on the surfaces of the rotating tube 4 and the branch pipe 6, and suction will be generated at the vacuum hood 74. Then, the sealing cover 2 is opened, and the meat slices to be thawed are placed on the branch pipe 6. The suction at the through holes is used to adsorb and fix the meat slices. After the meat slices are placed, the sealing cover 2 is closed. As the air inside the thawing box 1 is continuously extracted, the meat slices to be thawed inside the thawing box 1 will be in a vacuum environment, which is convenient for the subsequent heat transfer of high-temperature steam, thereby accelerating the thawing speed of the frozen meat slices. In the above steps, the vacuum assembly 7 is used not only to evacuate the interior of the thawing box 1 to enhance the subsequent heat transfer effect of the high-temperature steam, but also to cooperate with the branch pipe 6 to temporarily adsorb and fix the meat slices to be thawed, so that the meat slices to be thawed can be neatly spread out, which can enable the frozen meat slices to be fully heated later, thereby accelerating the thawing speed of the meat slices.

[0021] The steam supply component 9 is used to input high-temperature steam into the thawing box 1. The steam supply component 9 includes a steam supply pipe 91 and a second connecting pipe 92. The steam supply pipe 91 is movably sleeved inside the other end of the rotating pipe 4, and a steam supply valve is fixedly installed on the outside of the steam supply pipe 91. The second connecting pipe 92 is fixedly connected to the outside of the rotating pipe 4, and a nozzle 93 is fixedly installed on one side of the second connecting pipe 92. In this embodiment, when the interior of the thawing box 1 is evacuated to a vacuum environment, the vacuum pump 73 will continue to work for a period of time. At this time, the steam supply valve is opened to allow the high-temperature steam to be input into the interior of the rotating tube 4 along the steam supply pipe 91, flow along the No. 2 connecting pipe 92, and be sprayed out from the nozzle 93. At this time, the high-temperature steam will diffuse outward from one side of the inner cavity of the thawing box 1, and because the vacuum pumping component 7 on the other side of the inner cavity of the thawing box 1 is still working and generates negative pressure attraction, and the interior of the thawing box 1 is a closed space, a pressure difference will be generated, so that the high-temperature steam can quickly flow from one side of the inner cavity of the thawing box 1 to the other side, so that the internal space of the thawing box 1 can be quickly heat-transferred, thereby further accelerating the thawing speed of the frozen meat slices; In the above steps, when high-temperature steam is input into the interior of the thawing box 1, the vacuum assembly 7 can be used to accelerate the flow rate of the high-temperature steam, so that the high-temperature steam can fill the interior of the thawing box 1 in a short time, which also saves time for thawing frozen meat slices.

[0022] The driving assembly 8 is used to drive the rotating tube 4 to rotate. The driving assembly 8 includes a bearing plate 81. A driving motor 82 is fixedly installed on the top of the bearing plate 81. A driving gear 83 is fixedly sleeved on the output shaft of the driving motor 82. The outside of the driving gear 83 is meshedly connected with a driven gear 84. The driven gear 84 is fixedly sleeved on the outside of the other end of the rotating tube 4. The top of the driving gear 83 and the bottom of the driven gear 84 are meshed with each other. The thickness of the driving gear 83 is less than the thickness of the driven gear 84. In this embodiment, when high-temperature steam is input, the driving motor 82 is turned on, so that the driving gear 83 rotates, and the driving gear 83 drives the driven gear 84 to rotate, and the driven gear 84 drives the rotating tube 4 to rotate. At this time, the rotating tube 4 drives the second connecting tube 92 and the nozzle 93 to rotate, so that the ejected high-temperature steam will form a rotating flow trend, and combined with the suction of the vacuum assembly 7, the high-temperature steam can quickly fill the entire inner cavity of the thawing box 1; When the high-temperature steam is sucked into the No. 1 connecting pipe 72 from the exhaust hood 74, that is, when the surface of the exhaust pipe 71 is heated, the exhaust pump 73 and the exhaust valve are closed. At this time, due to the disappearance of negative pressure, the meat slices placed on the branch pipe 6 will fall, and the rotating pipe 4 will drive the circulation pipe 5 and the branch pipe 6 to rotate. The circulation pipe 5 and the branch pipe 6 can be used to turn the meat slices inside the thawing box 1, so that the meat slices can better absorb heat, thereby bringing convenience to the thawing of the meat slices; In the above steps, the driving assembly 8 can not only drive the rotating tube 4 to rotate, and cooperate with the circulation tube 5 and the branch tube 6 to flip the meat slices, so that the meat slices can better absorb the heat in the steam, but also can make the input high-temperature steam produce a spinning flow, further accelerating the diffusion speed of the high-temperature steam.

[0023] In summary, compared with most existing thawing devices, the frozen meat steam thawing device based on a vacuum environment in this embodiment has the following advantages: 1. By setting the vacuum pumping component 7, it is convenient to vacuum the interior of the thawing box 1 during the thawing of frozen meat, so that the high-temperature steam can efficiently diffuse and transfer heat in a vacuum environment, thereby accelerating the thawing speed of the frozen meat. At the same time, during the vacuum pumping process, the branch pipe 6 and the through holes opened on its surface can be used to temporarily adsorb and fix the meat slices to be thawed, so that the meat slices to be thawed can be neatly spread out, so that the frozen meat slices can be fully heated later, further accelerating the thawing speed of the meat slices. When the steam supply component 9 is used to input the high-temperature steam into the interior of the thawing box 1, the vacuum pumping component 7 can be used to generate a pressure difference in the thawing box 1, which will accelerate the flow speed of the high-temperature steam, prompting the internal space of the thawing box 1 to be quickly heat-transferred, indirectly accelerating the thawing speed of the frozen meat slices, thereby improving the working efficiency of the thawing device; 2. By setting up the driving component 8, it is convenient to drive the rotating tube 4 to rotate during the thawing process of frozen meat, and cooperate with the circulation tube 5 and the branch pipe 6 to form a stirring structure, and turn the meat slices scattered inside the thawing box 1, so that the meat slices can better absorb the heat in the steam. At the same time, when high-temperature steam is input, the driving component 8 will use the rotating tube 4 to drive the second connecting pipe 92 and the nozzle 93 to rotate, so that the ejected high-temperature steam will form a rotating flow trend, and combined with the suction of the vacuum component 7, the high-temperature steam can quickly fill the inner cavity of the entire thawing box 1, which saves time for thawing the frozen meat and speeds up the thawing speed, thereby further improving the working efficiency of the thawing device.

[0024] Embodiment 2

[0025] See also Figure 5-7 The frozen meat steam thawing device based on a vacuum environment of this embodiment adds an adjusting component 11 on the basis of the first embodiment. The adjusting component 11 is arranged on the outside of the circulation pipe 5, and the end of the adjusting component 11 is fixedly connected to the mounting plate 12, and the outside of the mounting plate 12 is fixedly connected to the scraper plate 13, and the material of the scraper plate 13 is an elastic material. The adjusting component 11 includes a reset spring 111 and a cylinder 112. The reset spring 111 is located between the circulation pipe 5 and the mounting plate 12. The cylinder 112 is fixedly connected to the outside of the circulation pipe 5, and the cylinder 112 is movably sleeved with a piston 113. The top of the piston 113 is fixedly connected with a movable rod 114. The end of the movable rod 114 is fixedly connected to the bottom of the mounting plate 12. The two ends of the reset spring 111 are respectively fixedly connected to the top of the circulation pipe 5 and the bottom of the mounting plate 12, and the movable rod 114 and the cylinder 112 are movably sleeved. In this embodiment, when the vacuum assembly 7 is working, negative pressure is generated inside the circulation tube 5, and the piston 113 in the cylinder 112 moves under the action of the negative pressure, so that the movable rod 114 retracts and pulls the mounting plate 12 closer to the circulation tube 5, causing the return spring 111 to be compressed and deformed. When the vacuum assembly 7 stops working, the meat slices originally adsorbed on the branch pipe 6 will scatter inside the thawing box 1. At this time, the inside of the circulation tube 5 will also lose the negative pressure, and the compressed return spring 111 needs to restore its elastic deformation and press the mounting plate 12 against the return spring 111. 12 applies force to make the mounting plate 12 move away from the circulation tube 5, and the mounting plate 12 will drive the movable rod 114 to extend, and at the same time the mounting plate 12 will drive the scraper plate 13 of elastic material to move, so that the scraper plate 13 is in contact with the inner wall of the thawing box 1, so that when the rotating tube 4 drives the circulation tube 5 to rotate, the scraper plate 13 will also rotate close to the inner wall of the thawing box 1, so that the scraper plate 13 can better drive the scattered meat slices to turn over, avoiding the problem of uneven heating of the meat slices due to accumulation, thereby improving the thawing effect of the frozen meat slices.

[0026] In summary, the frozen meat steam thawing device based on a vacuum environment of the present embodiment, by setting an adjustment component 11, can cooperate with the vacuum component 7 to adjust the positions of the mounting plate 12 and the scraper plate 13 during the thawing process of the frozen meat. When it is necessary to stir the frozen meat slices scattered inside the thawing box 1, the scraper plate 13 can be rotated close to the inner wall of the thawing box 1, so that the scraper plate 13 can better drive the scattered meat slices to turn over, avoiding the problem of uneven heating of the meat slices due to accumulation, thereby improving the thawing effect of the frozen meat slices.

[0027] Embodiment 3

[0028] The present invention also provides an operating method for steam thawing of frozen meat based on a vacuum environment, comprising the following steps: S1. First, open the vacuum pump 73 and the vacuum valve, and use the vacuum pipe 71 to extract air. At this time, negative pressure will be generated inside the circulation pipe 5 and the No. 1 connecting pipe 72, and suction will be generated at the through holes on the surfaces of the rotating tube 4 and the branch pipe 6, and suction will be generated at the vacuum hood 74. Then open the sealing cover 2, place the meat slices to be thawed on the branch pipe 6, and use the suction at the through holes to adsorb and fix the meat slices. After the meat slices are placed, close the sealing cover 2. As the air inside the thawing box 1 is continuously extracted, the meat slices to be thawed inside the thawing box 1 will be in a vacuum environment, which is convenient for the subsequent heat transfer of high-temperature steam, thereby accelerating the thawing speed of the frozen meat slices. S2. When the interior of the thawing box 1 is evacuated to a vacuum environment, the vacuum pump 73 will continue to work for a period of time. At this time, the steam supply valve is opened to allow the high-temperature steam to be input into the interior of the rotating tube 4 along the steam supply pipe 91, and flow along the No. 2 connecting pipe 92, and sprayed out from the nozzle 93. At this time, the high-temperature steam will diffuse outward from one side of the inner cavity of the thawing box 1. Since the vacuum pumping component 7 on the other side of the inner cavity of the thawing box 1 is still working and generates negative pressure attraction, and the interior of the thawing box 1 is a closed space, a pressure difference will be generated, so that the high-temperature steam can quickly flow from one side of the inner cavity of the thawing box 1 to the other side, so that the internal space of the thawing box 1 can be quickly heat-transferred, thereby further accelerating the thawing speed of the frozen meat slices; S3. When high-temperature steam is input, the driving motor 82 is turned on to rotate the driving gear 83, and the driving gear 83 drives the driven gear 84 to rotate, and the driven gear 84 drives the rotating tube 4 to rotate. At this time, the rotating tube 4 drives the second connecting tube 92 and the nozzle 93 to rotate, so that the ejected high-temperature steam will form a rotating flow trend, and combined with the suction of the vacuum assembly 7, the high-temperature steam can quickly fill the entire inner cavity of the thawing box 1; S4. When the high-temperature steam is sucked into the No. 1 connecting pipe 72 from the exhaust hood 74, that is, when the surface of the exhaust pipe 71 is heated, the exhaust pump 73 and the exhaust valve are closed. At this time, due to the disappearance of the negative pressure, the meat slices placed on the branch pipe 6 will fall, and the rotating pipe 4 will drive the circulation pipe 5 and the branch pipe 6 to rotate. The circulation pipe 5 and the branch pipe 6 can be used to turn the meat slices inside the thawing box 1, so that the meat slices can better absorb heat, thereby bringing convenience to the thawing of the meat slices; S5. When the vacuum assembly 7 stops working, the return spring 111 in the compressed state needs to restore its elastic deformation and apply force to the mounting plate 12, so that the mounting plate 12 moves away from the circulation tube 5, and the mounting plate 12 will drive the movable rod 114 to extend. At the same time, the mounting plate 12 will drive the scraper plate 13 made of elastic material to move, so that the scraper plate 13 is in contact with the inner wall of the thawing box 1. In this way, when the rotating tube 4 drives the circulation tube 5 to rotate, the scraper plate 13 will also rotate close to the inner wall of the thawing box 1, so that the scraper plate 13 can better drive the scattered meat slices to turn over, so that the frozen meat slices can be fully heated, thereby improving the thawing effect of the frozen meat slices.

The device for steam thawing frozen meat in a vacuum environment according to claim 8, characterized in that: The two ends of the return spring (111) are respectively fixedly connected to the top of the flow tube (5) and the bottom of the mounting plate (12), and the movable rod (114) and the cylinder (112) are movably sleeved.

10. A method for steam thawing of frozen meat in a vacuum environment, comprising the following steps: S1. Provide a thawing device; S2, firstly, using the vacuum pumping component (7) to vacuum the interior of the thawing box (1), so that in a vacuum environment, the heat transfer efficiency of the subsequent high-temperature steam can be enhanced, and at the same time, the sealing cover (2) is opened, and the meat slices to be thawed are placed on the branch pipe (6). Due to the operation of the vacuum pumping component (7), suction is generated at the through holes on the surface of the branch pipe (6), so that the placed frozen meat slices can be temporarily adsorbed and fixed; S3, then using the steam supply component (9) to input high-temperature steam into the interior of the thawing box (1), and because the vacuum component (7) is still working, a pressure difference is generated inside the thawing box (1), and the high-temperature steam will quickly flow and diffuse inside the thawing box (1); S4, the driving assembly (8) is then used to drive the rotating tube (4) to rotate, and the rotating tube (4) drives the second connecting tube (92) and the nozzle (93), so that the ejected high-temperature steam forms a rotating flow trend, and cooperates with the operation of the vacuum assembly (7) to accelerate the flow and diffusion speed of the high-temperature steam; S5. Finally, when the vacuum pumping component (7) is closed, the frozen meat slices on the branch pipe (6) will be scattered inside the thawing box (1), and the rotating tube (4) will drive the circulation tube (5) and the branch pipe (6) to form a stirring structure to stir the scattered frozen meat slices. At the same time, the adjusting component (11) will cause the scraping plate (13) to rotate in contact with the inner wall of the thawing box (1), so that the frozen meat slices can be turned over better, so that the frozen meat slices can be fully heated; It is characterized in that the thawing device is a frozen meat steam thawing device based on a vacuum environment as described in any one of claims 1 to 9.
