Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to an intermittent water injection type meat bubbling thawing device. Background Art

[0002] In the food processing, thawing meat is a crucial step. Because frozen meat forms ice crystals at low temperatures, the water in the meat will become hard and difficult to cut and process. The thawing process can melt these ice crystals and restore the meat to its original structure and texture, making it easier to process and handle.

[0003] In the traditional thawing process, the thawing methods mainly include room temperature thawing, water immersion thawing, etc., but these methods have many limitations. Thawing at room temperature may cause the surface of the food to thaw first while the center is still frozen, forming a temperature difference, which is conducive to the growth of bacteria and poses a potential threat to food safety. Thawing by water immersion may cause the loss of nutrients in the food, such as the dissolution of water-soluble vitamins. At the same time, the penetration of water may also change the texture of the food and affect the taste. Therefore, a thawing device dedicated to meat came into being; compared with the traditional thawing process, the thawing device dedicated to meat food can not only quickly thaw meat food from a frozen state, greatly reducing time and labor costs, and improving production efficiency; it can also evenly thaw meat products to avoid local overheating or uneven thawing. The quality of the food has deteriorated, thereby maintaining the original taste and nutritional value of the food.

[0004] In the prior art, for example, a patent with application number CN201910362870.6 discloses: a meat food thawing device, in which a spray mechanism, a placement mechanism and a bubbling mechanism are arranged in sequence from top to bottom in the thawing tank, the spray mechanism includes a plurality of spray pipes fixed on the top of the thawing tank, and a plurality of spray heads are connected to the lower end of the spray pipe; the placement mechanism includes a rotating shaft rotatably connected in the thawing tank, a first placement barrel is fixed on the rotating shaft, a second placement barrel is hinged on the first placement barrel, and the first placement barrel and the second placement barrel are buckled into a cylindrical shape; the bubbling mechanism includes a bubbling tube fixed in the thawing tank, the upper end of the bubbling tube is in an arc shape that is attached to the outer walls of the first placement barrel and the second placement barrel, and a plurality of air outlets are arranged at the upper end of the bubbling tube. The scheme of the present invention can improve the thawing rate.

[0005] Although the above device can achieve the purpose of thawing meat food; however, when using the above device, the meat food to be thawed needs to be stacked in the placement barrel for rolling thawing, which easily leads to the problem that the outer layer of meat food thaws faster and the inner layer of meat food thaws slower, and the meat food cannot be thawed evenly. At the same time, there is also the possibility that the outer layer of meat food will be over-thawed and cause nutrient loss of the food; in addition, when the placement barrel in this device is continuously rolled, it is easy to squeeze the outer layer of meat food, which will further destroy the integrity of the meat food and is not conducive to subsequent processing operations; in summary, a meat thawing device needs to be designed to solve the above problems.

The loading mechanism 5 also includes a middle bearing groove 52 upwardly provided at the middle section of the loading frame 51 and a connecting screw 56 symmetrically provided on the middle bearing groove 52, the connecting screw 56 is penetrated through the snap ring block 13, and an external thread matching the internal thread is provided on the connecting screw 56.

[0045] The bubbling mechanism 7 includes a blast pipe 72 arranged on the bottom of the thawing tank 1, a plurality of blast ports 721 opened on the blast pipe 72, and a blast device 71 installed outside the thawing tank 1, and the blast pipe 72 is connected to the blast device 71.

[0046] When implementing the device of the present application, the meat food to be thawed is first loaded into the loading frame 51. In order to facilitate placement, the loading mechanism 5 needs to be driven up first; when driving, the first motor 16 is started first, and the first motor 16 drives the driving gear 15 to rotate. The rotating driving gear 15 drives the driven gear 131 meshing with it to rotate. The rotating driven gear 131, under the action of the synchronous belt 14, causes the two snap ring blocks 13 to rotate synchronously; since the connecting screw 56 and the snap ring block 13 are threadedly connected, the connecting screw 56 is synchronously displaced upward while the snap ring block 13 rotates, and drives the loading mechanism 5 to move upward until the bottom of the loading mechanism 5 moves out of the thawing tank 1, and the first motor 16 is turned off, and the loading mechanism 5 stops moving; in this process, the support plate 12 extends upward to a fixed height so that the loading mechanism 5 can be completely moved out of the thawing tank 1 without causing motion interference. Then, the movable side plate 54 is pulled outward so that the movable side plate 54 rotates and unfolds, so that the meat food to be thawed can be evenly spread in the loading frame 51. The uniform spreading can ensure that the meat food is evenly thawed; after the spreading is completed, the movable side plate 54 is released by hand, and under the pulling force of the second spring 55, the movable side plate 54 rotates and resets, so that the processing efficiency can be improved; after all the meat food on both sides are laid, the first motor 16 is started to drive the loading mechanism 5 to move downward until the roller 62 is correspondingly stuck in the bottom groove 53, and the first motor 16 is turned off to stop the displacement of the loading mechanism 5; then a certain amount of water is injected into the thawing tank 1 so that the meat food to be thawed is completely immersed; and in the thawing process, in order to speed up the thawing speed, the limiting wheel 3, the blowing device 71 and the second motor 68 can be started respectively.

[0047] When the limiting wheel 3 is started to rotate, the high block 32 and the low rotating wheel 31 rotate synchronously, and the water injection pipe 44 abutting against the limiting wheel 3 is continuously moved back and forth up and down under the action of the first spring 26 and the limiting position of the low rotating wheel 31 and the high block 32; when the water injection pipe 44 is displaced to the highest point, the water inlet 43 just coincides with the water outlet 24, and at this time, the thawing water in the water storage tank 21 flows into the thawing tank 1 through the water outlet 24, the water inlet 43 and the water injection pipe 44; when the water injection pipe 44 is displaced to the lowest point, the water outlet 24 and the water inlet 43 are completely misaligned, and the circulating water flow is disconnected; during the continuous rotation of the limiting wheel 3, the movable water injection assembly 4 cooperates with the water storage mechanism 2 to realize intermittent water injection, and the water level in the thawing tank 1 also continuously rises; during the rising process, the overflowing thawing water is discharged through the thawing tank 1. The water flows through the drainage hopper 17 into the reflux assembly 8, and the thawed water flows into the reflux pipe 22 after being filtered by the filter plate 82; at this time, the reflux pump 27 can be started to input the refluxed thawed water into the water storage tank 21 for reuse, so that the design can avoid the waste of water resources; during intermittent water injection, when the water is injected into the thawing pool, a large number of tiny bubbles will be generated due to the increase in water temperature and the stirring of the water; these bubbles form a bubble cloud in the water, which continues to rise and impact the surface of the meat, thereby effectively accelerating the thawing speed of the meat food; similarly, the use of intermittent water injection can not only significantly reduce the amount of water used and save water resources; it can also better control the temperature gradient during the thawing process, so that the meat food is heated more evenly during the thawing process, thereby improving the thawing efficiency. When the blower 71 is started, the blower 71 blows gas into the blower pipe 72 and generates a large number of bubbles through the blower port 721. The large number of bubbles will continuously generate impact force during the rising process. This impact force can effectively destroy the frozen structure of meat, promote the breaking and thawing of ice crystals, and thus accelerate the thawing speed. When the second motor 68 is started, the second motor 68 drives the driving screw 67 to rotate, and the rotating driving screw 67 drives the displacement block 66 to move. The displacement block 66 drives the rolling gear 63 and the connecting rod 61 arranged between the rolling gear 63 to move. Since the rolling gear 63 is meshed with the limited rack 64 below, the rolling gear 63 rotates while displacing, so the roller 62 is synchronously displaced and rotated. During the movement, the roller 62 continuously pushes the meat food in the loading frame 51, making it easier to separate the meat food, thereby accelerating the thawing speed; in this process, the pressure rod 65 clamped on the rolling gear 63 at the other end can ensure that the rolling gear 63 is always meshed with the limited rack 64, thereby ensuring the stable movement of the roller 62. After thawing is completed, the reflux pump 27, the limiting wheel 3, the second motor 68 and the blowing device 71 are turned off, and then the first motor 16 is started to drive the loading mechanism 5 to move upward; finally, the movable side plate 54 is pulled to take out the thawed meat food.In addition, it should be noted that the first motor 16, reflux pump 27, limiting wheel 3, second motor 68 and blowing device 71 in the device of the present application are all existing technologies and only need to realize corresponding functions. The specific working principles will not be repeated in this technical solution.

[0048] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
