Description

Technical Field

[0001] The present invention relates to the technical field of quick-freezing of meat rolls, and particularly relates to a quick-freezing device for frozen rolled mutton. Background Art

[0002] Frozen rolled mutton is a common frozen food. Usually, mutton is processed specially and rolled into a roll shape for frozen storage. Generally, fresh mutton is selected, such as sheep meat or goat meat. To ensure the taste and quality, the tenderloin and other parts of the sheep with tender meat and appropriate fat and lean ratio are often selected. Some high-end frozen rolled mutton will use the meat of specific breeds of sheep, and the mutton of these breeds has unique flavors and tastes.

[0003] During the process of cutting mutton into rolls, low temperature can effectively inhibit the activity of enzymes in mutton. The protein and fat of mutton are well preserved, and the toughness and elasticity of the meat fibers are maintained in the best state. Secondly, low temperature makes the texture of mutton become hard and stable. During the slicing process, the stable texture ensures that the mutton will not be deformed or broken due to the cutting force of the slicing machine. The slicing machine can accurately cut the mutton into slices with uniform thickness and regular shapes, which not only improves the aesthetics of the product but also ensures that the mutton is evenly heated during cooking, further improving the cooking effect and eating experience.

[0004] For example, the Chinese patent with the publication number CN218604859U discloses a cutting device for producing mutton rolls with good heat preservation effect; in this utility model, by adding a storage box to this device, this device can store and store mutton rolls without the need for staff to use other storage objects to store mutton rolls, and by setting a refrigeration device in the storage box, the storage box has heat preservation ability, thereby preventing the mutton rolls in the storage box from thawing and deteriorating, effectively improving the practicability of this device.

[0005] However, there are still some deficiencies in the above device during actual use: 1. By setting a refrigeration device in the storage box, the above device makes the storage box have heat preservation ability. However, it takes a certain amount of time to cool inside the heat preservation box. The frozen mutton needs time to be cut into rolls, and the later cut mutton may thaw. The freezing time inside the heat preservation box is slow, which may cause the mutton to deform due to thawing.

[0006] 2. By using the refrigeration device to keep the mutton warm, the above device can only freeze the outside of the rolled mutton inside the heat preservation box, resulting in a slower freezing speed of the inner mutton and uneven freezing effects of the whole mutton. Due to the large temperature difference between the inside and outside, the hard shell formed by rapid freezing on the outside will hinder the dissipation of internal heat, making the internal mutton stay in a relatively high temperature range for a long time. This will not only cause uneven water distribution inside and outside the mutton but also affect the structural stability of the meat fibers.

[0007] Therefore, under the viewpoints stated above, it is of great significance to improve and perfect the cutting device for producing mutton rolls with good heat preservation effect, which can not only quickly freeze the mutton after cutting the rolls, but also ensure that the internal and external freezing speeds of the mutton are the same during freezing, thus ensuring the quality of the mutton.

At the same time, due to the rapid freezing process, the ice crystals formed by the moisture inside the meat rolls are small and evenly distributed, avoiding the destruction of the meat roll tissue structure caused by too large ice crystals, and enabling the shape of the meat rolls to be completely retained.

[0019] Second, by installing a placing structure inside the storage box, the quickly frozen meat rolls are neatly stacked in the storage box, greatly ensuring the contact area between the meat rolls in the storage box and the cold air in the storage box. And the cold air can freely circulate around the meat rolls, continuously providing a low-temperature environment for the meat rolls and further maintaining the fresh state of the meat rolls. This spaced arrangement effectively prevents the meat rolls from sticking together and avoids the shape deformation caused by mutual contact and extrusion. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Invention

[0031] The following will be described in detail with reference to the attached Figures 1-9 The embodiments of the present invention will be described in detail.

[0032] The embodiment of the present application discloses a rapid freezing device for frozen rolled mutton. It should be noted that the present invention is mainly applied in the process of quick freezing of meat rolls. In terms of technical effects, it can avoid the problem that the mutton cut and coiled later may thaw, and the freezing time in the insulation box is slow, which may cause the mutton to deform due to thawing; further, the present invention can also solve the problem that only the outside of the rolled mutton can be frozen, resulting in a slow freezing speed of the inner mutton and uneven freezing effect of the whole mutton.

[0033] Embodiment 1: Refer to Figure 1 And Figure 2As shown in the figure, it includes a fixing plate 1. A fixing device 10 and a cutting and rolling knife 11 are installed on the fixing plate 1. The frozen meat roll is fixed by the fixing device 10, and then the meat roll is cut into wound thin slices by the cutting and rolling knife 11. One side of the fixing device 10 is provided with a conveying pipe 12. A storage box 13 is arranged on the side of the conveying pipe 12 far from the cutting device. The cut meat roll will enter the storage box 13 through the conveying pipe 12 for collection and storage. A freezing structure 2 for quick-freezing mutton is arranged on the conveying pipe 12. Inside the conveying pipe 12, the cut meat roll is quick-frozen to ensure its freshness and shape.

[0034] Moreover, freezing devices are arranged on the side walls of both the conveying pipe 12 and the storage box 13 to ensure that the meat roll is always in a low-temperature state during the process of transfer and collection.

[0035] The freezing structure 2 includes an air delivery pipe 20. Liquid nitrogen is delivered through the air delivery pipe 20, and the inside of the meat roll is quick-frozen by the liquid nitrogen. The air delivery pipe 20 penetrates through the conveying pipe 12 along the length direction of the conveying pipe 12. A docking pipe 21 is slidably arranged at the other end of the conveying pipe 12 in the length direction. A plurality of output holes 22 are formed on the docking pipe 21. A push plate 23 is slidably arranged inside the conveying pipe 12 along its length direction through a tension spring. The push plate 23 is sleeved outside the docking pipe 21.

[0036] After the meat roll drops into the conveying pipe 12, by driving the docking pipe 21 to approach the meat roll, the docking pipe 21 is inserted into the middle gap of the meat roll. After being completely inserted, the push plate 23 moves synchronously, pushing the meat roll towards the direction of the air delivery pipe 20 until the docking pipe 21 is communicated with the air delivery pipe 20. The liquid nitrogen in the air delivery pipe 20 enters the docking pipe 21 and is output from the output port of the docking pipe 21 to quick-freeze the inside of the meat roll.

[0037] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in the figure, it is a schematic structural diagram of driving the docking pipe 21 to be communicated with the air delivery pipe 20. Specifically, a clamping device 3 for driving the two to be communicated is arranged on the air delivery pipe 20 and the docking pipe 21. The clamping device 3 includes a clamping ring 30. The clamping ring 30 is slidably arranged inside the air delivery pipe 20 close to the docking pipe 21 through a tension spring. A plugging block 31 is slidably installed at one end of the air delivery pipe 20. The plugging block 31 is connected to the clamping ring 30. A pushing pin 32 for actively abutting against the plugging block 31 is arranged on the docking pipe 21.

[0038] During the process of the docking pipe 21 gradually moving towards the air delivery pipe 20, first, the pushing pin 32 on the docking pipe 21 will approach the plugging block 31, pushing the plugging block 31 to slide into the air delivery pipe 20 until the docking pipe 21 contacts the air delivery pipe 20. At this time, the air delivery pipe 20 is communicated with the clamping pipe.

[0039] After the quick-freezing is completed, the clamping pipe moves away from the gas transmission pipe 20. At this time, the blocking block 31 loses the acting force of the needle abutment 32. Under the action of the tension spring, the clamping ring 30 is driven back to its initial state. Furthermore, the clamping ring 30 drives the blocking block 31 to block the opening of the gas transmission pipe 20 again.

[0040] Refer to Figure 2 , Figure 3 and Figure 4 As shown in the figures, it is a schematic structural diagram for preventing the meat roll from dropping directly; specifically, a baffle 140 passing through the conveying pipe 12 is also slidably arranged inside the conveying pipe 12 along its height direction. The baffle 140 can prevent the meat roll from directly dropping from the conveying pipe 12 into the storage box 13 before the meat roll is quick-frozen. A driving shaft 141 is rotatably installed at the bottom inside the storage box 13. A driving groove is formed inside the driving shaft 141. A connecting shaft 142 connected to the baffle 140 is arranged inside the driving groove. A threaded groove is formed on the side wall of the driving groove. A driving block (not shown in the figure) that slides inside the threaded groove is installed on the connecting shaft 142. By rotating the driving shaft 141 and using the threaded groove on the driving shaft 141 to cooperate with the driving block on the connecting shaft 142, the connecting shaft 142 can move up and down, and then drive the baffle 140 to move up and down.

[0041] Refer to Figure 2 , Figure 3 and Figure 4 As shown in the figures, it is a schematic structural diagram for driving the docking pipe 21 to move; specifically, a moving member 4 for driving the docking pipe 21 and the push plate 23 to slide is also installed on the conveying pipe 12 and the storage box 13. The moving member 4 includes a first screw rod 40. The first screw rod 40 is rotatably arranged inside the storage box 13 along the length direction of the conveying pipe 12. A connecting seat 41 threadedly connected to the first screw rod 40 is slidably arranged at the bottom of the storage box 13. A push rod 42 connected to the docking pipe 21 is arranged on the connecting seat 41. A sliding groove for the push rod 42 to slide is formed on the conveying pipe 12.

[0042] When the first screw rod 40 rotates, the connecting seat 41 can slide inside the storage box 13, and then drive the docking pipe 21 to slide. When the push rod 42 on the connecting seat 41 slides into the conveying pipe 12, it will push the push plate 23 to slide inside the conveying pipe 12. When the quick-freezing is completed and the docking pipe 21 moves away from the gas transmission pipe 20, the push plate 23 loses the acting force of the push rod 42 and returns to its initial state under the action of the tension spring.

[0043] Refer to Figure 2 , Figure 3 and Figure 4As shown, it is a schematic structural diagram of the structure that drives the drive shaft 141 to rotate; specifically, a synchronizing member 5 for driving the drive shaft 141 to rotate is further provided in the storage box 13. The synchronizing member 5 includes a synchronizing rack 50. The synchronizing rack 50 is provided on the connecting seat 41, and a synchronizing gear 51 that is movably engaged with the synchronizing rack 50 is sleeved outside the drive shaft 141.

[0044] During the process of the first screw 40 driving the connecting seat 41 to move, the synchronizing rack 50 on the connecting seat 41 will approach the synchronizing gear 51, and the drive shaft 141 will be driven to rotate through the synchronizing gear 51. During the process of the connecting seat 41 approaching the air delivery pipe 20, the drive shaft 141 drives the baffle 140 to descend. When the connecting seat 41 starts to move away from the air delivery pipe 20, the meat roll will directly fall into the storage box 13 without the barrier of the baffle 140 at this time. At this time, the first screw 40 continues to rotate, so that the synchronizing rack 50 on the connecting seat 41 moves away from the air delivery pipe 20. When the synchronizing rack 50 on the connecting seat 41 approaches the synchronizing gear 51, the drive shaft 141 drives the baffle 140 to rise at this time to block the next meat roll.

[0045] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, it is a schematic structural diagram of the structure for placing the meat roll into the storage box 13; specifically, a placing structure 6 for placing the meat roll is provided inside the storage box 13. The placing structure 6 includes a folded placing plate 60. Feeding holes 61 are formed in the upper plate surface at each bending part of the placing plate 60, and a plurality of partition plates 62 are slidably arranged at equal intervals along the height direction of the storage box 13 on the placing plate 60.

[0046] The quick-frozen meat roll will enter the placing plate 60 in the storage box 13 through the delivery pipe 12, and roll down layer by layer through the feeding holes 61 on the placing plate 60. After each meat roll drops, the corresponding partition plate 62 will slide up to block between each meat roll, so that the meat rolls are neatly stacked in the storage box 13, ensuring the contact area between the meat rolls in the storage box 13 and the cold air in the storage box 13, and preventing the meat rolls from sticking together.

[0047] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, it is a schematic structural diagram of the structure that drives the partition plate 62 to rise and fall; specifically, a driving member 7 for driving the partition plate 62 to rise and fall is provided inside the storage box 13. The driving member 7 includes a connecting plate 70 provided at the bottom of one end of the partition plate 62, and a second screw 71 is rotatably installed on the side wall of the storage box 13. The connecting plate 70 is threadedly sleeved on the second screw 71.

[0048] By rotating the second screw 71 to drive the connecting plate 70 to rise and fall, the partition plate 62 is further driven to rise and fall.

[0049] Reference 6, Figure 7 and Figure 8 as shown, which is a schematic structural diagram of driving the second screw 71 to rotate; specifically, an actuating member 8 for driving the second screw 71 to rotate is further installed inside the storage box 13. The actuating member 8 includes a zigzag plate 80. An actuating rack 81 is slidably arranged on the zigzag plate 80. A guide rail is further arranged on the zigzag plate 80. The actuating rack 81 slides on the zigzag plate 80 through the guide rail. An actuating gear 82 meshing with the actuating rack 81 is installed on the second screw 71.

[0050] The guide rail enables the actuating rack 81 to slide on the zigzag plate 80 and gradually move upward from the bottom. Whenever the meat roll enters the storage box 13, the guide rail makes the actuating rack 81 slide a certain distance and come into contact with the actuating gear 82, driving the second screw 71 to rotate, causing the corresponding partition plate 62 to rise and block the meat roll. It should be noted that the actuating rack 81 always remains horizontal to ensure that the actuating rack 81 is always horizontal when it contacts the actuating gear 82.

[0051] Embodiment Two: On the basis of Embodiment One, in order to further improve the freezing rate of the mutton roll; a linkage member 9 is also proposed, which is beneficial to synchronously quick-freezing the cut meat roll while the cutting roll knife 11 cuts the meat roll, ensuring the freshness of the mutton roll.

[0052] Reference Figure 2 and Figure 9 as shown, which is a schematic diagram of the mechanism for driving the first screw 40 to rotate; specifically, the synchronizing member 5 includes a synchronizing shaft 90. The synchronizing shaft 90 is rotatably installed inside the storage box 13. The upper end of the synchronizing shaft 90 is connected to the output shaft of the cutting roll knife 11 through bevel gears, and the other end is connected to the first screw 40 through bevel gears.

[0053] Whenever the cutting roll knife 11 cuts the meat roll once, the output shaft of the cutting roll knife 11 rotates and drives the first screw 40 to rotate through bevel gear transmission. Furthermore, every time the meat roll is cut, the first screw 40 drives the freezing structure 2 inside the conveying pipe 12 to work once.

[0054] It should be noted that the diameter of the bevel gear at the lower end of the synchronizing shaft 90 is much larger than the diameter of the bevel gear on the first screw 40.

[0055] So that every time the synchronizing shaft 90 rotates, the first screw 40 rotates more turns, ensuring the working efficiency of the connecting seat 41 on the first screw 40.

[0056] During operation: In the first step, the frozen meat roll is fixed through the fixing device 10, and then the cutting roll knife 11 is used to cut the meat roll into wound thin slices.

[0057] Step 2: The first screw 40 rotates to enable the connecting seat 41 to slide inside the storage box 13, thereby driving the docking pipe 21 to slide. During the process that the docking pipe 21 gradually moves towards the gas transmission pipe 20, the needle 32 on the docking pipe 21 will approach the plugging block 31, pushing the plugging block 31 to slide inside the gas transmission pipe 20 until the docking pipe 21 contacts the gas transmission pipe 20. At this time, the gas transmission pipe 20 is connected to the clamping pipe.

[0058] Step 3: The liquid nitrogen in the gas transmission pipe 20 enters the docking pipe 21 and is output from the output port of the docking pipe 21 to quickly freeze the inside of the meat roll.

[0059] Step 4: The quickly frozen meat roll enters the placement plate 60 inside the storage box 13 through the conveying pipe 12, rolls layer by layer through the feeding holes 61 on the placement plate 60, and enables the driving rack 81 to slide on the zigzag plate 80 through the guide rail and gradually move upward from the bottom.

[0060] Step 5: Whenever the meat roll enters the storage box 13, the guide rail drives the driving rack 81 to contact the driving gear 82, driving the second screw 71 to rotate, raising the corresponding partition plate 62 to block the meat roll, enabling the meat roll to be neatly stacked in the storage box 13, ensuring the contact area between the meat roll in the storage box 13 and the cold air in the storage box 13, and preventing the meat rolls from sticking together.

[0061] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0062] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
