Description
Technical Field
[0001] The utility model relates to the technical field of pet food processing, in particular to a raw meat block thawing device. Background Art
[0002] At present, in the pet food processing industry, especially in the processing of some meat and fish, in order to ensure the supply of food processing raw materials and to ensure constant production throughout the year, a large amount of the required raw materials must be processed over a period of time, and then these raw materials are stored in a cold storage in a frozen manner for normal and long-term production. Therefore, before the frozen meat or fish raw materials come out of the cold storage for processing, they must be thawed first, otherwise they cannot be processed.
[0003] Announcement No. CN219961854U proposes a raw material thawing device for pet food processing. When the frozen pet meat block raw material is put into the mixing drum, the driving motor can drive the rotating disk and the connecting shaft to rotate, and the warm water in the mixing drum can be used to thaw the meat block. At the same time, the stirring rod rotates to hit the meat block, thereby accelerating the separation speed of the meat block; however, in the device, the raw material meat block is thawed by direct stirring, contact and heating, which will cause a large amount of gravy in the meat block to be lost in the water, and the freshness and taste of the subsequent meat block are reduced. At the same time, a large amount of oil is floating in the water in layers, which requires frequent oil drainage, and the thawing effect needs to be further improved. Utility Model Content
[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a raw meat block thawing device.

[0007] This device can minimize the loss of meat juice when thawing raw pet meat. Compared with natural thawing, thawing by immersion in water at room temperature shortens the time and effectively ensures the freshness and taste of the meat. At the same time, there is no need to frequently drain oil and replace thawing water, and the thawing effect is further improved.

[0010] Furthermore, the thawing box is symmetrically provided with electric push rods, and the electric push rods are connected to a cover body.
[0011] The above solution can realize automatic lifting and lowering of the cover body through the electric push rod, thereby facilitating the taking and placing of materials.
[0012] Furthermore, a flexible rubber layer is provided on the surface of the protrusion.
[0013] The above solution can reduce the probability of the sealing bag being damaged during the contact between the protrusion and the sealing bag by providing the rubber layer, and further reduce the probability of the loss of meat juice in the meat while effectively thawing.
[0014] Furthermore, the water changing assembly includes a suction pump and a three-way pipe. A suction pump is arranged at the bottom of the thawing box and is connected to the suction pump.

[0015] Furthermore, a liquid level sensor electrically connected to the suction pump is provided in the thawing box.
[0016] The above solution realizes the injection and replacement process of thawing water through the water replacement component, and the liquid level sensor can provide feedback and accurately control the amount of water added.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] Compared with the existing technology, this device can minimize the loss of meat juice when thawing raw pet meat blocks.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:
[0023] like Figure 1 As shown, a raw meat thawing device comprises a thawing box 1 and a plurality of sealed bags containing meat blocks to be thawed, the sealed bags are not shown in the figure, a first cylinder 12 is symmetrically arranged in the thawing box 1, and the first cylinder 12 is connected to a drain plate 13 that is slidably matched with the inner wall of the thawing box 1,
[0024] The scheme is refined. Slide rails 11 are symmetrically arranged in the thawing box 1. A drain plate 13 is slidably fitted between the two slide rails 11. The drain plate 13 is provided with a plurality of protrusions 14 and drain holes (the drain holes are not numbered in the figure). A cover body 2 is movably arranged on the thawing box 1. A second cylinder 21 is arranged on the cover body 2. The second cylinder 21 is connected to a lower pressure plate 22 which is located inside the thawing box 1 and is hollow inside. An air injection assembly is arranged on the lower pressure plate 22 to realize the surging of water during the thawing process. A water changing assembly is arranged at the bottom of the thawing box 1.
[0025] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, the gas injection assembly includes a blowing pipe 23, an air pump 31 and a hose 32. A plurality of blowing pipes 23 are arranged on the lower pressure plate 22 and the blowing pipes 23 are connected to the interior of the lower pressure plate 22. A plurality of air holes 24 are circumferentially arranged on each blowing pipe 23. An air pump 31 is arranged on the cover body 2, and the air pump 31 is connected to the interior of the lower pressure plate 22 through a hose 32.
[0026] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, the water changing assembly includes a suction pump 16 and a three-way pipe 17. The suction pump 16 is arranged at the bottom of the thawing box 1 and is connected to the suction pump 16. The suction pump 16 is connected to the three-way pipe 17. Electromagnetic valves are arranged on the two pipelines of the three-way pipe 17 and are respectively connected to the water tank and the waste liquid tank. The water tank and the waste liquid tank are not shown in the figure.
[0027] For further optimization of the solution, a liquid level sensor electrically connected to the suction pump 16 is provided in the thawing box 1. The liquid level sensor is not shown in the figure and belongs to the prior art, and its principle will not be described.
[0028] It should be noted that the first cylinder 12, the second cylinder 21, the air pump 31, the suction pump 16, the liquid level sensor and the two valves are all electrically connected to the controller and the two valves are independently electrically controlled. The controller is not shown in the figure.
[0029] The workflow of this utility model:
[0030] First, open the cover 2 and then place several sealed bags containing meat to be thawed on the drain plate 13 in sequence (the sealed bags are not stacked). It should be noted that the air inside the sealed bag itself has been discharged in advance to ensure that water and the frozen raw meat are in full contact. Due to the presence of the protrusion 14, the contact area between the meat and the drain plate 13 can be reduced, thereby improving the thawing effect;
[0031] Then close the cover 2, and then the controller controls the first cylinder 12 to work and drive the drain plate 13 to move to the lower area of the thawing box 1 (when the sealed bag is initially placed, the drain plate 13 moves to the top area of the thawing box 1), and then the controller controls the suction pump 16 to work to draw water from the water tank and inject it into the thawing box 1. At this time, the liquid level sensor can feedback and accurately control the amount of water added. After the water is quantitatively added to the thawing box 1, the controller controls the second cylinder 21 to work and drive the lower pressure plate 22 to move down below the water surface (the air is blown at this time). The pipe 23 does not contact the drain plate 13 and the raw meat block). The significance of this design is to avoid the problem that the meat block partially floats above the liquid surface during the thawing process, thereby causing the raw meat block to be unable to be completely immersed in the water. Then the controller controls the air pump 31 to work. The air pump 31 can pressurize the clean air source at room temperature and pass it into the lower pressure plate 22. Then the air flow flows along the air blowing pipe 23 and finally sprays out from the plurality of air holes 24 into the water. At this time, the thawing water can be turned over and the meat block can be turned over in the thawing water to further improve the thawing effect.
[0032] After the batch of meat blocks is thawed, the cover body 2 is opened first (the lower pressure plate 22 has moved back to the initial position before the cover body 2 is opened). After the cover body 2 is moved away, the controller controls the first cylinder 12 to extend so that the drain plate 13 moves upward. At this time, the sealed bag can be gradually separated from the thawing water and drained. After the draining is completed, the subsequent meat blocks can be discharged in a centralized manner, and then a new batch of meat blocks can be added to start a new round of pet raw material meat block thawing process;
[0033] During the thawing process, the presence of the sealed bag can prevent the meat from directly contacting water and causing a large amount of meat juice to be lost. At the same time, the amount of oil mixed in the water is greatly reduced, so there is no need to drain the oil frequently. The freshness and taste of the meat are kept good. After the fixed number of thawing times is completed, the suction pump 16 can reversely suck to realize the transfer of waste liquid to the waste liquid tank, and then replace a batch of clean water sources to carry out the thawing process again.
[0034] Compared with the existing technology, this device can minimize the loss of meat juice when thawing raw pet meat blocks. The thawing time by immersion in water at room temperature is shorter than that of natural thawing and the freshness and taste of the meat blocks are effectively guaranteed. At the same time, there is no need to frequently drain oil and replace thawing water, and the thawing effect is further improved.
[0035] In some embodiments, a flexible rubber layer is provided on the surface of the protrusion 14, which is not shown in the figure. By providing the flexible rubber layer, this embodiment can reduce the probability of damage to the sealing bag during the contact between the protrusion 14 and the sealing bag, and further reduce the probability of loss of gravy in the meat while effectively thawing.
[0036] In other embodiments, Figure 1 As shown, the thawing box 1 is symmetrically provided with electric push rods 15, and the electric push rods 15 are connected to the cover body 2; in this embodiment, the electric push rods 15 can realize automatic lifting of the cover body 2 to facilitate taking out and putting out materials.
[0037] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
