Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of food thawing equipment, specifically a food thawing cabinet. Background Technology
[0002] Food processing companies, central kitchens, or restaurants typically use water soaking, microwave, or natural thawing when defrosting food. However, microwave ovens are not suitable for defrosting large quantities and the defrosting process is uneven. Water soaking can contaminate food and water forks, and natural thawing is slow. If frozen food is placed from the freezer into the defrosting chamber in advance, it can ensure safe thawing and save energy. However, during natural thawing, the food will be soaked in the thawed water, which may affect the taste and safety of the food.
[0003] Chinese Patent No. ZL202020277997.6 discloses a multifunctional defrosting rack, including a handle, a support rail, and casters. The defrosting rack has a cuboid structure, with a caster connected to the bottom of each corner. The support rail is fixedly connected to the top, and the upper left of the support rail is obliquely fixed to the handle. The defrosting rack includes an adjustment module and a drainage module. The adjustment module allows for adjusting the position of frozen food according to the defrosting progress and the storage position according to the size of the frozen food. The drainage module can collect the defrosting liquid generated during defrosting. However, when food is placed on the support plate or partition during defrosting, it is easy for the food to slip off the edge of the support plate or partition, causing contamination. This is inconvenient to place. After defrosting, the food needs to be manually removed layer by layer, which is inconvenient to operate and has technical problems of low efficiency and high labor costs. Summary of the Invention
[0004] The technical problem to be solved by this utility model is how to improve the efficiency of placing and taking out thawed food. The purpose of this utility model is to provide a food defrosting cabinet that can move thawed food layer by layer downwards through the flipping of the flap, while making it convenient to place food and draining defrosting water in a timely manner.
[0005] The technical solution adopted by this utility model is as follows: a food defrosting cabinet includes a support frame. The support frame is provided with protective mesh panels on the left, right, rear, and top sides. The support frame is provided with multiple horizontal bars parallel to the horizontal plane. Multiple horizontal bars at the same height are connected end to end to form a rectangle. A middle bar is provided between the front and rear horizontal bars. The two ends of the middle bar are fixedly connected to the middle of the front horizontal bar and the middle of the rear horizontal bar at the same horizontal height, respectively. Two flaps are rotatably connected to each horizontal bar and are symmetrically distributed along the middle bar. Multiple mesh holes are evenly distributed on the flaps. A sliding rod is slidably connected to each middle bar. Multiple protrusions are provided on both sides of the sliding rod. Multiple notches are provided on the edge of the flaps near the middle bar. The multiple protrusions on the sliding rods are adapted to the multiple notches on the flaps, and the width of the notches is greater than the width of the protrusions. A transfer cart is also provided at the bottom of the support frame.
[0006] The following benefits can be achieved by using the food defrosting cabinet provided by this utility model:
[0007] (1) After placing the food to be thawed on each flip plate, it can be thawed naturally or placed in the thawing chamber to accelerate thawing. The protective net prevents the food to be thawed from falling and causing contamination, while facilitating air flow and heat transfer. The thawing water produced after the protective net is thawed can flow down through the mesh holes on each flip plate and eventually be discharged. The structure is simple and easy to use.
[0008] (2) It is convenient and quick to take out and put in food to be thawed. When the protrusion on the slide bar is misaligned with the notch on the flip plate, the protrusion can be used to support the flip plate and prevent it from rotating, so that the food to be thawed can be placed stably on the flip plate; the slide bar can slide on the middle bar. When the protrusion on the slide bar moves with the slide bar to the bottom of the notch on the edge of the flip plate and aligns with the notch, the flip plate will start to rotate without the support of the protrusion, so that the thawed food will fall down layer by layer from the tilted flip plate and finally fall into the transfer car. The operation is convenient.
[0009] Preferably, both ends of the flap are provided with a pivot, which is located at an eccentric position in the horizontal direction at the end of the flap, with the eccentric direction away from the notch, and the two pivots on each flap are coaxial.
[0010] By setting a pivot and placing both pivots on each flip plate at an eccentric position away from the notch in the horizontal direction at the end of the flip plate, the flip plate can rotate around the pivot. The side of the flip plate with the notch on the left and right sides of the pivot is heavier than the other side. This allows the side of the flip plate with the notch to automatically flip downwards around the pivot under the action of gravity in its natural state, making it easy to quickly discharge thawed food downwards.
[0011] Preferably, the bottom of the crossbars on both sides of the bracket is provided with multiple first baffles. When the upper and lower sides of the flap are flush with the upper and lower sides of the crossbar, the first baffle at the bottom of the crossbar is located at the bottom of the flap and abuts against the bottom of the flap.
[0012] The first baffle at the bottom of the crossbars on both sides of the bracket allows the flap to be supported by a protrusion on the side with the notch when it is in a horizontal position, while the side of the flap away from the notch is supported by the first baffle. This prevents the flap from over-flipping and avoids the side of the flap away from the notch from rotating downwards, causing the food to be thawed to fall down from the side of the flap away from the notch. This ensures that all food to be thawed falls down from the side closer to the notch, making it easier to collect.
[0013] Preferably, a first fixing rod is fixedly connected to the bottom of one end of the middle rod, and a limiting rod is fixedly connected to the other end; a first mounting plate and a second mounting plate are respectively provided at the bottom of both ends of the slide rod, and the slide rod restricts the degree of freedom of the slide rod through the first mounting plate and the second mounting plate at its bottom, so that the slide rod is sleeved on the middle rod and can only slide along the front and back of the middle rod.
[0014] The first and second mounting plates enable the slide bar to slide along the central rod, and when the slide bar moves, it can drive all the protrusions at the bottom of the slide bar to move together.
[0015] Preferably, the upper front end of the slide bar is provided with a push-pull plate.
[0016] The sliding plate facilitates the movement of the slide bar, making operation convenient.
[0017] Preferably, the first mounting plate is disposed on the slide rod near one end of the first fixed rod, and a second fixed rod is fixedly connected to the first mounting plate, and a tension spring is also connected between the first fixed rod and the second fixed rod.
[0018] By connecting the first mounting rod on the central rod to the second mounting rod on the slide rod using a tension spring, the slide rod can automatically return to its original position under the action of the tension spring after sliding. When the flip plate is in a horizontal state, the protrusion on the slide rod is kept offset from the notch on the flip plate to prevent the flip plate from continuing to flip. This avoids uncold food from sliding directly down the tilted flip plate after flipping when placing food to be thawed. There is no need to repeatedly check the position of the protrusion on the slide plate, making it convenient to use.
[0019] Preferably, the second mounting plate is disposed on the slide rod near one end of the limiting rod, and the second mounting plate is provided with a first limiting groove, and the limiting rod is disposed in the first limiting groove and slidably connected to the first limiting groove.
[0020] The sliding position of the slide bar is restricted by the first limiting groove and the limiting rod inside the first limiting groove. When the slide bar retracts under the tension of the tension spring, one end of the first limiting groove at the bottom of the slide bar abuts against the limiting rod. When the slide bar is pushed so that the other end of the first limiting groove abuts against the limiting rod, the protrusion at the bottom of the slide bar aligns with the notch at the bottom of the flip plate, which facilitates the rotation of the flip plate and prevents the slide bar from moving too far. This prevents the protrusion and notch from continuing to misalign after aligning during the slide bar's movement to one side, causing interference between the flip plate and the protrusion and resulting in the slide bar being unable to flip.
[0021] Preferably, the width of the transfer vehicle is smaller than the width of the support, and the length of the transfer vehicle is greater than the length of the flip plate;
[0022] By making the width of the transfer cart smaller than the width of the support frame, it is easier to move the transfer cart into the support frame. The length of the transfer cart is greater than the length of the flip plate to prevent interference between the transfer cart and the flip plate, thus avoiding the problem of the flip plate being unable to flip.
[0023] Preferably, a second baffle is fixedly connected to both sides at the rear of the bottom of the bracket, and the distance between the two second baffles is less than the width of the transfer vehicle.
[0024] The second baffle facilitates the positioning of the transfer vehicle and restricts its placement. When the transfer vehicle is positioned inside the bracket and against the second baffle, its internal carrying space faces directly below the flip panel, making it easy to catch thawed food that slides off the flip panel and preventing food from falling outside the transfer vehicle and causing contamination.
[0025] Preferably, the transfer vehicle is equipped with casters at all four corners of its bottom.
[0026] The omnidirectional wheels facilitate the movement of the transfer vehicle.
[0027] Preferably, the top of both sides of the transfer vehicle is equipped with lifting rings.
[0028] By setting up lifting rings, it is easy to lift the transfer vehicle to different locations using lifting equipment.
[0029] Preferably, the transfer vehicle has a discharge port on one side wall, and a discharge tilting door is provided on the discharge port, with the top of the discharge tilting door rotatably connected to the top of the discharge port.
[0030] The discharge port facilitates material unloading. A discharge tilting door is installed on the discharge port to block the discharge port when not unloading, preventing material leakage from the discharge port.
[0031] Preferably, a second limiting groove is fixedly connected to the top of the side of the unloading tilting door, and a slider is fixedly connected to the top of the side wall of the transfer vehicle near the unloading port. The slider is set in the second limiting groove and slidably connected to the second limiting groove.
[0032] The second limiting groove and slider facilitate the restriction of the opening and closing angle of the unloading tilting door, so that after unloading, the unloading tilting door can automatically re-cover the unloading port under the action of gravity. This prevents the unloading tilting door from rotating too much during unloading, which would require manual tilting of the unloading tilting door to the position of re-covering the unloading port after unloading, thereby reducing labor costs and operation time.
[0033] Preferably, the bottom of the side of the unloading tilting door is rotatably connected with a buckle, and the bottom of the side wall of the transfer vehicle near the unloading port is fixedly connected with a hanging rod. When the unloading tilting door is tilted and completely covers the unloading port, the buckle and the hanging rod can be engaged with each other.
[0034] By setting up buckles and hanging rods, the buckles can be fastened to the hanging rods to fix the unloading tilting door when not unloading, preventing the unloading tilting door from rotating at will and preventing materials from spilling from the unloading port. When unloading, rotating the buckles to disengage them from the hanging rods allows the unloading tilting door to rotate freely within the range limited by the second limit groove, making it easy to discharge the thawed food loaded in the transfer vehicle from the unloading port.

Detailed Implementation
[0054] The following will be combined with the appendix Figure 1-17 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.
[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0056] Example 1
[0057] The following description, in conjunction with specific embodiments, provides further details. Figure 1-17 As shown, this embodiment is a food defrosting cabinet, including a support 1. Protective mesh panels 11 are provided on the left, right, rear, and top sides of the support 1. Multiple horizontal bars 2 parallel to the horizontal plane are provided inside the support 1. Multiple horizontal bars 2 at the same height are connected end-to-end to form a rectangle. A middle rod 21 is provided between the front and rear horizontal bars 2. The two ends of the middle rod 21 are fixedly connected to the middle parts of the front and rear horizontal bars 2 at the same horizontal height, respectively. Two flaps 3 symmetrically distributed along the middle rod 21 are rotatably connected to each horizontal bar 2. Multiple mesh holes 31 are evenly distributed on the flaps 3. Sliding rods 4 are slidably connected to each middle rod 21. Multiple protrusions 42 are provided on both sides of the sliding rods 4. Multiple notches 33 are provided on the edge of the flaps 3 near the middle rod 21. The multiple protrusions 42 on the sliding rods 4 and the multiple notches 33 on the flaps 3 are all... The bracket 1 is designed with the width of the notch 33 greater than the width of the protrusion 42. The bottom of the bracket 1 is also equipped with a transfer cart 5. The protective net prevents the food to be thawed from falling and causing contamination, while facilitating airflow and heat transfer. The thawing water produced after the protective net is thawed can flow down layer by layer through the mesh 31 on each flap 3 and eventually be discharged. The structure is simple and easy to use. It is convenient and quick to take out and put in the food to be thawed. The protrusion 42 can be used to support the flap 3 to prevent the flap 3 from rotating at will. The slide bar 4 can slide on the middle bar 21. When the protrusion 42 on the slide bar 4 moves with the slide bar 4 to the bottom of the notch 33 on the edge of the flap 3 and aligns with the notch 33, the flap 3 will start to rotate without the support of the protrusion 42. This causes the thawed food to fall down layer by layer from the tilted flap 3 and finally fall into the transfer cart 5. The operation is convenient.
[0058] Reference Figure 6 and Figure 15As shown, in this embodiment, both ends of the flip plate 3 are provided with a rotating shaft 32. The rotating shaft 32 is located at an eccentric position in the horizontal direction at the end of the flip plate 3, away from the notch 33. The two rotating shafts 32 on each flip plate 3 are coaxial. By setting the rotating shaft 32 and making the two rotating shafts 32 on each flip plate 3 located at an eccentric position in the horizontal direction at the end of the flip plate 3 away from the notch 33, the flip plate 3 can rotate around the rotating shaft 32. The side of the flip plate 3 with the notch 33 on the left and right sides of the rotating shaft 32 is heavier than the other side. This allows the side of the flip plate 3 with the notch 33 to automatically flip downwards around the rotating shaft 32 under the action of gravity in its natural state, which facilitates the rapid downward discharge of thawed food.
[0059] Reference Figure 2 or Figure 7 or Figure 10 As shown, in this embodiment, the bottom of the crossbars 2 on both sides of the bracket 1 is provided with multiple first baffles 12. When the upper and lower sides of the flip plate 3 are flush with the upper and lower sides of the crossbar 2, the first baffles 12 at the bottom of the crossbar 2 are located at the bottom of the flip plate 3 and abut against the bottom of the flip plate 3. The first baffles 12 at the bottom of the crossbars 2 on both sides of the bracket 1 enable the flip plate 3 to be in a horizontal state. The side of the flip plate 3 with the notch 33 can be supported by the protrusion 42, and the side of the flip plate 3 away from the notch 33 is supported by the first baffles 12, thereby preventing the flip plate 3 from overturning. At the same time, it prevents the side of the flip plate 3 away from the notch 33 from rotating downward, causing the food to be thawed to fall downward from the side of the flip plate 3 away from the notch 33. This ensures that all the food to be thawed falls downward from the side close to the notch 33, making it easy to collect.
[0060] Reference Figure 3 or Figure 7 and Figure 16 As shown, in this embodiment, a first fixing rod 211 is fixedly connected to the bottom of one end of the middle rod 21, and a limiting rod 212 is fixedly connected to the other end; a first mounting plate 43 and a second mounting plate 45 are respectively provided at the bottom of both ends of the slide rod 4. The slide rod 4 restricts the degree of freedom of the slide rod 4 through the first mounting plate 43 and the second mounting plate 45 at its bottom, so that the slide rod 4 is sleeved outside the middle rod 21 and can only slide back and forth along the middle rod 21. The slide rod 4 can slide along the middle rod 21 through the first mounting plate 43 and the second mounting plate 45. When the slide rod 4 moves, it can drive all the protrusions 42 at the bottom of the slide rod 4 to move together.
[0061] Reference Figure 1 or Figure 6 or Figure 14 or Figure 16 As shown, in this embodiment, a push-pull plate 41 is provided at the upper front end of the slide bar 4. The push-pull plate 41 facilitates the movement of the slide bar 4 and makes operation convenient.
[0062] Reference Figure 3 or Figure 7 or Figure 14 As shown, in this embodiment, the first mounting plate 43 is disposed on the slide rod 4 near the end of the first fixed rod 211, and a second fixed rod 431 is fixedly connected to the first mounting plate 43. A tension spring is also connected between the first fixed rod 211 and the second fixed rod 431. By connecting the first mounting rod on the middle rod 21 and the second mounting rod on the slide rod 4 with the tension spring, the slide rod 4 can automatically reset under the action of the tension spring after sliding. When the flip plate 3 is in a horizontal state, the protrusion 42 on the slide rod 4 is kept offset from the notch 33 on the flip plate 3 to prevent the flip plate 3 from continuing to flip. This avoids the unfrozen food from sliding directly down the tilted flip plate 3 after flipping when the flip plate 3 is flipped, without the need to repeatedly check the position of the protrusion 42 on the slide plate, making it convenient to use.
[0063] Reference Figure 3 or Figure 7 or Figure 10 As shown, in this embodiment, the second mounting plate 45 is disposed on the slide rod 4 near one end of the limiting rod 212. The second mounting plate 45 is provided with a first limiting groove 451. The limiting rod 212 is disposed in the first limiting groove 451 and is slidably connected to the first limiting groove 451. The sliding position of the slide rod 4 is restricted by the first limiting groove 451 and the limiting rod 212 in the first limiting groove 451. When the slide rod 4 retracts under the tension of the tension spring, one end of the first limiting groove 451 at the bottom of the slide rod 4 abuts against the limiting rod 212. When the slide rod 4 is pushed so that the other end of the first limiting groove 451 abuts against the limiting rod 212, the protrusion 42 at the bottom of the slide rod 4 aligns with the notch 33 at the bottom of the flip plate 3, which facilitates the rotation of the flip plate 3 and prevents the slide rod 4 from moving too far, causing the protrusion 42 and the notch 33 to continue to misalign after alignment during the movement of the slide rod 4 to one side, resulting in interference between the flip plate 3 and the protrusion 42 and thus the inability to flip.
[0064] Reference Figure 1 or Figure 2 or Figure 5 or Figure 6 or Figure 13 As shown, in this embodiment, the width of the transfer vehicle 5 is less than the width of the support 1, and the length of the transfer vehicle 5 is greater than the length of the flip plate 3. By making the width of the transfer vehicle 5 less than the width of the support 1, it is easier to move the transfer vehicle 5 into the support 1. The length of the transfer vehicle 5 is greater than the length of the flip plate 3, which can prevent the transfer vehicle 5 from interfering with the flip plate 3 and avoid the problem that the flip plate 3 cannot be flipped.
[0065] Reference Figure 5As shown, in this embodiment, two second baffles 13 are fixedly connected to the rear sides of the bottom of the support 1. The distance between the two second baffles 13 is less than the width of the transfer vehicle 5. The second baffles 13 facilitate the positioning of the transfer vehicle 5 and restrict the placement of the transfer vehicle 5. When the transfer vehicle 5 is located inside the support 1 and abuts against the second baffles 13, the internal bearing space of the transfer vehicle 5 faces directly below the flip plate 3, which facilitates the reception of thawed food that slides off the flip plate 3 and prevents the food from falling outside the transfer vehicle 5 and causing contamination.
[0066] Reference Figure 1 or 2 or Figure 17 As shown, in this embodiment, the transfer vehicle 5 is provided with universal wheels 51 at all four corners of its bottom, which facilitates the movement of the transfer vehicle 5.
[0067] Reference Figure 17 As shown, in this embodiment, the top of both sides of the transfer vehicle 5 is provided with lifting rings 52, which facilitates the lifting of the transfer vehicle 5 to different positions by using lifting equipment.
[0068] Reference Figure 17 As shown, in this embodiment, a discharge port 53 is provided on one side wall of the transfer vehicle 5, and a discharge tilting door 531 is provided on the discharge port 53. The top of the discharge tilting door 531 is rotatably connected to the top of the discharge port 53. The discharge port facilitates material discharge. The discharge tilting door 531 on the discharge port 53 facilitates the use of the discharge tilting door 531 to block the discharge port 53 when not discharging, so as to prevent material from leaking from the discharge port 53 when not discharging.
[0069] Reference Figure 17 As shown, in this embodiment, a second limiting groove 533 is fixedly connected to the top of the side of the unloading tilting door 531, and a slider 55 is fixedly connected to the top of the side wall of the transfer vehicle 5 near the unloading port 53. The slider 55 is disposed in the second limiting groove 533 and slidably connected to the second limiting groove 533. The second limiting groove 533 and the slider 55 facilitate the restriction of the opening and closing angle of the unloading tilting door 531, so that after unloading, the unloading tilting door 531 can automatically re-cover the unloading port 53 under the action of gravity. This prevents the rotation angle of the unloading tilting door 531 from being too large during unloading, which would require manual tilting of the unloading tilting door 531 to the position of re-covering the unloading port 53 after unloading, thereby reducing labor costs and operation time.
[0070] Reference Figure 2 or Figure 4As shown, in this embodiment, a buckle 532 is rotatably connected to the bottom of the side of the unloading tilting door 531, and a hanging rod 54 is fixedly connected to the bottom of the side wall of the transfer vehicle 5 near the unloading port 53. When the unloading tilting door 531 is tilted and completely covers the unloading port 53, the buckle 532 and the hanging rod 54 can be fastened to each other. By setting the buckle 532 and the hanging rod 54, the unloading tilting door 531 can be fixed when not unloading, preventing the unloading tilting door 531 from rotating at will and preventing the material from spilling from the unloading port 53. When unloading, rotating the buckle 532 to disengage the buckle 532 from the hanging rod 54 allows the unloading tilting door 531 to rotate freely within the range limited by the second limiting groove 533, which facilitates the discharge of the thawed food loaded in the transfer vehicle 5 from the unloading port 53.
[0071] Example 2
[0072] When using this invention, place the food defrosting cabinet in a clean place above the drain trough inside the defrosting chamber. Check the status of each flip plate 3, ensuring all flip plates 3 are horizontal. Since a tension spring connects the first fixing rod 211 on the central rod 21 and the second fixing rod 431 on the sliding plate, the sliding rod 4 returns to its original position under the action of the tension spring. That is, the protrusion 42 on the sliding rod 4 is offset from the notch 33 on the flip plate 3. Therefore, when the flip plate 3 is horizontal, the protrusion 42 at the bottom of the sliding rod 4 must be located at the bottom of the flip plate 3. The part is offset from the notch 33 on the flip plate 3. The protrusion 42 on the slide rod 4 and the first baffle 12 on the crossbar 2 limit the two sides of the flip plate 3, so that the flip plate 3 can not be flipped after being kept in a horizontal state, thus making it convenient to place food to be thawed on the flip plate 3. If the flip plate 3 is not in a horizontal state, the slide rod 4 can be pushed by the push-pull plate 41 first, and then the flip plate can be adjusted to a horizontal state. Then the push-pull plate 41 can be released, so that the slide rod 4 can be reset under the action of the tension spring. The protrusion 42 at the bottom of the slide rod 4 can restrict the degree of freedom of flip plate flipping.
[0073] Place the food to be thawed on each flip plate 3. The protective mesh plate 11 and the mesh holes 31 on the flip plate 3 facilitate air flow and heat transfer, which helps to accelerate thawing. At the same time, the mesh holes 31 on the flip plate 3 facilitate the downward drainage of thawing water generated after thawing, preventing the food from being soaked in the thawing water itself, which could lead to bacterial growth, spoilage, and deterioration of the taste of the thawed food.
[0074] After the food is thawed, the transfer cart 5 is moved to the inner side of the bottom of the support 1 via the casters 51, ensuring that the buckle 532 on the unloading flip door 531 is engaged with the hanging rod 54 on the transfer cart 5. The position of the transfer cart 5 is then restricted by the second baffle 13, so that when the transfer cart 5 abuts against the second baffle 13, the load-bearing space of the transfer cart 5 is directly below the flip plate 3. Then, the push-pull plate 41 is pushed from top to bottom, causing the slide rod 4 to slide along the middle rod 21. When the limiting rod 212 on the slide rod 4 moves from one end of the first limiting groove 451 to the other end and abuts against the other end of the first limiting groove 451, the protrusion 42 moves with the slide rod 4 to directly below the notch 33 on the side of the flip plate 3, and the bottom of the flip plate 3 loses the protrusion 4. Supported by 2, the flip plate 3 rotates around the pivot 32 under the weight of its own weight and the weight of the thawed food on the flip plate 3. Since the side of the flip plate 3 away from the notch 33 is supported and limited by the first baffle 12, the side of the flip plate 3 with the notch 33 can only be flipped downwards, so that the thawed food on the flip plate 3 slides down the flip plate 3 to the next layer. By pushing the slide bar 4 layer by layer, all the thawed food eventually falls down layer by layer and finally falls into the transfer car 5. When all the thawed food on the flip plate 3 has fallen into the transfer car 5, the transfer car 5 is pulled out and can be moved to the next work station by using the casters 51 or by using the hoisting equipment and the lifting rings 52 on the transfer car 5.
[0075] During unloading, the buckle 532 is disengaged from the hook, causing the unloading tilting door 531 to flip and expose the unloading port 53 on the transfer vehicle 5. The side of the transfer vehicle 5 away from the unloading port 53 is then lifted upwards, allowing the thawed food to be discharged from the unloading port 53. Because the transfer vehicle 5 is equipped with a second limiting groove 533 and a slider 55, the opening and closing angle of the unloading tilting door 531 can be limited, thus preventing the unloading tilting door 531 from flipping too far. At the same time, it is easy to control the speed and position of the thawed food as it falls. After unloading, when the transfer vehicle 5 is kept horizontal, the unloading tilting door 531 can automatically flip back to its original position under the action of gravity to cover the unloading port 53 again, without the need for manual adjustment of the state of the unloading tilting door 531. After cleaning the transfer vehicle 5, the buckle 532 on the unloading tilting door 531 is fastened to the hanging rod 54 on the transfer vehicle 5, and it can be used for the next thawing operation.
