Description

Technical Field

[0001] The present invention relates to the technical field of food processing, in particular to a cooling device for food processing. Background Art

[0002] Food processing refers to the grain milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as processing activities of foods such as vegetables, fruits and nuts that directly use agricultural, forestry, animal husbandry and fishery products as raw materials.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention drives two sets of conveyor rollers to rotate synchronously through a motor, so that the food on the surface of the conveyor belt is moved into the inside of the box. The cold air generated by the air cooler is transported to the inside of the shell through the cold air duct, and then ejected through the guide port on one side of the shell. Since the multiple sets of shells are symmetrically arranged in pairs, the cold air ejected from the symmetrical guide ports will form convection cold air, which directly acts on the food on the surface of the conveyor belt through the convection cold air to achieve cooling of the food. The convection cold air formed by the guide port can act on the food comprehensively from different directions, so that all parts of the food can be evenly cooled, effectively avoiding the problem of uneven local cooling.

[0022] 2. The present invention rotates the conveyor roller, and the ring installed inside the conveyor roller rotates synchronously. The knocking rod sliding inside the ring will continuously contact the stationary cam. During the rotation of the conveyor roller, the cam will squeeze the knocking rod, causing the knocking rod to slide in the ring, so that the knocking rod continuously knocks the inner wall of the conveyor roller to generate high-frequency slight vibration. The conveyor roller transmits the generated vibration to the surface of the conveyor belt, so that the vibration can reduce the adhesion of food to the surface of the conveyor belt, reduce food residue, and ensure the cleanliness of the conveyor belt. It also helps the food to move more smoothly during the transmission process, thereby improving the stability and efficiency of the overall processing. At the same time, one end of the vibration rod is synchronously affected by the vibration, so that the vibration generated by the conveyor belt will drive the food to jump slightly, so that different parts of the food are more evenly contacted with the cold air generated by the cooling mechanism, further improving the uniformity of cooling, and some poorly formed foods can be detected through slight vibration, which is convenient for timely screening out unqualified products and ensuring the quality of food processing.

[0023] 3. In the present invention, during the rotation of the conveying roller, the conveying roller drives the gear to rotate, and the gear drives the eccentric wheel to rotate synchronously, so that the eccentric wheel drives the pulling rod to move back and forth inside the casing, and a part of the gas is sucked into the inside of the casing, and then transported to the inside of the air storage pipe through the gas pipe and ejected through the nozzle, so that the impurities on the scraper surface can be blown to the inside of the collection box for storage, avoiding the accumulation of impurities on the surface of the scraper. In addition, the knocking rod drives the top rod to reciprocate and squeeze the diaphragm B, so that the diaphragm B squeezes the hydraulic oil in the inner cavity of the conveying roller, and the push plate drives the extrusion rod to squeeze the diaphragm A, thereby increasing the gas pressure in the air storage pipe and making the impact force of the ejected airflow greater. At the same time, the push block contacts the inclined block and pushes the baffle to rotate a certain angle, so that the wind ejected from the nozzle blows along the baffle to the side of the conveying roller, and the enhanced airflow is used to assist in cleaning impurities with strong adhesion on the surface of the conveying roller, thereby further improving the overall cleaning efficiency.

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See Figures 1 to 8As shown, the present invention provides a cooling device for food processing, comprising a frame 1, two sets of conveying rollers 2 are rotatably provided inside the frame 1, a box 3 is welded to the surface of the frame 1, and a conveyor belt 11 is sleeved on the surface of the two sets of conveying rollers 2;

[0036] A cooling mechanism 5 is provided inside the box 3. The cooling mechanism 5 includes multiple groups of cold air pipes 51 provided inside the frame 1. The bottom ends of the multiple groups of cold air pipes 51 are connected to a shell 52. The side wall of the shell 52 is provided with a guide port 53. A collection shell 55 is installed inside the frame 1.

[0037] It should be noted that when the food needs to be cooled, the food is first placed on the surface of the conveyor belt 11, and then the motor is started. The motor drives the two sets of conveyor rollers 2 to rotate synchronously. Under the action of the conveyor rollers 2, the food on the surface of the conveyor belt 11 is moved to the inside of the box 3 and enters the cooling area. Then the air cooler 54 is started, and the cold air generated by the air cooler 54 is transported to the inside of the shell 52 through the cold air duct 51, and then ejected through the guide port 53 on one side of the shell 52. Since the multiple sets of shells 52 are arranged symmetrically in pairs, the cold air ejected from the symmetrical guide ports 53 will form convection cold air, which directly acts on the food on the surface of the conveyor belt 11 through the convection cold air to achieve cooling of the food. The convection cold air formed by the guide port 53 can act on the food from different directions, so that all parts of the food can be cooled evenly, reducing the amount of food in the box 3. The irregular internal diffusion allows the cold air to act on the food to the greatest extent, greatly improving the utilization rate of the cold air. Compared with the traditional one-way blowing cooling method, it can achieve faster cooling speed with the same cold air volume, shorten the food cooling time, improve processing efficiency, and effectively avoid the problem of uneven local cooling;

[0038] At the same time, the convective cold air will form an upward wind after docking, and the cooled hot air will enter the interior of the collecting shell 55, reducing the leakage of cold air to the external environment, avoiding a sudden drop in the ambient temperature of the device or energy waste caused by the diffusion of cold air, and a part of the hot air inside the collecting shell 55 will enter the interior of the air outlet shell 57 through the connecting pipe 56, and then be ejected through the nozzle of the air outlet shell 57 to act on the surface of the food, so that the ejected hot air can dry the residual moisture on the surface of the food, avoiding frost on the surface of the food due to the temperature drop during the cooling process, thereby ensuring the original taste of the food, and another part of the hot air inside the air outlet shell 57 is convenient for the subsequent cleaning mechanism 7 to extract and utilize, thereby improving the utilization rate of resources.

[0039] A vibration mechanism 6 is provided inside the conveyor roller 2. The vibration mechanism 6 includes a fixed shaft 61 installed inside the conveyor roller 2, and one end of the fixed shaft 61 is fixed to the outer wall of the mounting frame 1. A cam 62 is sleeved on the surface of the fixed shaft 61. A collar 63 is installed inside the conveyor roller 2. A knocking rod 64 slides inside the collar 63. A vibration rod 66 is provided inside the conveyor belt 11. One end of the vibration rod 66 is in contact with the side wall of the conveyor roller 2, and the other end of the vibration rod 66 is in contact with the inner surface of the conveyor belt 11.

[0040] It should be noted that when the conveyor roller 2 rotates under the drive of the motor, the fixed shaft 61 inside the conveyor roller 2 remains stationary because one end is fixed to the outer wall of the frame 1, and the cam 62 sleeved on the surface of the fixed shaft 61 also remains stationary. As the conveyor roller 2 rotates, the ring 63 installed inside the conveyor roller 2 rotates synchronously, and the knocking rod 64 sliding inside the ring 63 will continuously contact the stationary cam 62. Since the cam 62 has a convex structure, during the rotation of the conveyor roller 2, the cam 62 will squeeze the knocking rod 64, causing the knocking rod 64 to slide in the ring 63. When the knocking rod 64 is released from the squeezing of the cam 62, it is reset under the action of the spring A65, causing the knocking rod 64 to continuously knock on the inner wall of the conveyor roller 2 to generate high-frequency slight vibration. The conveyor roller 2 transmits the generated vibration to the surface of the conveyor belt 11, so that the vibration can reduce the adhesion of food to the surface of the conveyor belt 11, reduce food residue, ensure the cleanliness of the conveyor belt 11, and also help the food move more smoothly during the conveying process, thereby improving the stability and efficiency of the overall processing.

[0041] In addition, one end of the vibration rod 66 that is in contact with the side wall of the conveyor roller 2 is synchronously affected by the vibration, and then the vibration is transmitted to the middle position of the conveyor belt 11 that is in contact with it. When the food passes the top of the vibration rod 66, the vibration generated by the conveyor belt 11 will cause the food to jump slightly. On the one hand, the slight jumping of the food can allow the cold air to smoothly contact the bottom of the food, so that the bottom that was originally difficult to cool due to contact with the conveyor belt 11 can be cooled, and each part of the food can be more evenly contacted with the cold air generated by the cooling mechanism 5, further improving the uniformity of cooling; on the other hand, some poorly formed foods can be detected through slight vibration, such as baked foods such as bread and cakes. If the internal structure is loose and the food is poorly formed, it will break or become loose under the action of vibration, which is convenient for timely screening out unqualified products and ensuring the quality of food processing.

[0042] A cleaning mechanism 7 is provided at one end of the frame 1. The cleaning mechanism 7 includes an air storage pipe 71 mounted at the top of the frame 1. A nozzle 72 is mounted at the bottom end of the air storage pipe 71. A diaphragm A73 is mounted on the side wall of the nozzle 72. A scraper 74 is mounted on the inner wall of the frame 1. An air extraction mechanism 8 is provided between the collection shell 55 and the air storage pipe 71.

[0043] An auxiliary mechanism 9 for enhancing the cleaning of impurities is provided on one side of the air storage pipe 71 .

[0044] It should be noted that when the conveyor belt 11 rotates, the scraper 74 fits tightly with the conveyor belt 11 and can scrape out impurities remaining on its surface. At the same time, when the conveyor roller 2 is rotating, the conveyor roller 2 drives the gear 81 to rotate. Since the gear 81 is meshed and connected with the eccentric wheel 82, the gear 81 drives the eccentric wheel 82 to rotate synchronously, so that the eccentric wheel 82 drives the pulling rod 84 to move back and forth inside the sleeve 83 through the eccentric structure, and sucks part of the gas inside the collection shell 55 into the interior of the sleeve 83 through the exhaust pipe 85, and then transports it to the interior of the air storage pipe 71 through the air supply pipe 86 and sprays it out through the nozzle 72. Since the nozzle 72 is designed to be flat, the wind sprayed by the nozzle 72 blows vertically to the surface of the scraper 74, so that the impurities on the surface of the scraper 74 can be blown to the inside of the collection box for storage, thereby avoiding the accumulation of impurities on the surface of the scraper 74.

[0045] In addition, when the knocking rod 64 moves back and forth, it synchronously drives the push rod 67 to move, and the push rod 67 reciprocates to squeeze the diaphragm B10, so that the diaphragm B10 squeezes the hydraulic oil in the inner cavity of the conveyor roller 2. The hydraulic oil enters the cross pipe 91 through the connecting pipe, squeezes the push plate 92 to move, and the push plate 92 drives the squeezing rod 94 to squeeze the diaphragm A73, thereby increasing the gas pressure in the air storage pipe 71 and making the impact force of the ejected airflow greater. At the same time, when the push plate 92 moves, it drives the push block 98 to move. The push block 98 contacts the inclined block 97 and pushes the baffle 96 to rotate a certain angle, so that the wind ejected from the nozzle 72 blows toward the side of the conveyor roller 2 along the baffle 96, and uses the enhanced airflow to assist in cleaning impurities with strong adhesion on the surface of the conveyor roller 2, thereby further improving the overall cleaning efficiency.

[0046] See Figure 3 As shown, the guide port 53 is set to be tilted downward, and each two groups of shells 52 are set symmetrically. When the air is sprayed out in a tilted downward direction through the guide port 53, symmetrical convection cold air is formed, which effectively improves the cooling effect and cooling uniformity of the food.

[0047] See Figures 2 to 3 As shown, an air outlet shell 57 is installed on the side wall of the box body 3, and a connecting pipe 56 is connected between the collecting shell 55 and the air outlet shell 57. An air cooler 54 is installed above the cold air pipe 51. After the collecting shell 55 collects the cooled hot air, part of the hot air in the collecting shell 55 is transported to the air outlet shell 57 through the connecting pipe 56. Finally, the hot air is discharged by the air outlet shell 57 and acts on the food to treat the surface of the food to avoid frost during cooling.

[0048] See Figure 4As shown, the vibration rod 66 is set in an L shape, and its diameter gradually decreases from the end close to the conveyor roller 2 to the end close to the conveyor belt 11, which can make the vibration more concentrated when transmitted from the conveyor roller 2 to the conveyor belt 11, reduce the loss of vibration energy during the transmission process, and enable the conveyor belt 11 to obtain a more effective vibration effect, thereby better driving the food to jump slightly, improving the cooling uniformity and the ability to detect loose food. The outer wall of the ring 63 is provided with a spring A65, one end of the spring A65 is fixedly connected to the inner wall of the ring 63, and the other end of the spring A65 is fixedly connected to the bottom end of the knocking rod 64. When the cam 62 squeezes the knocking rod 64 to make it slide in the ring 63, the spring A65 will be compressed; and when the knocking rod 64 is released from the squeezing of the cam 62, the spring A65 can quickly push the knocking rod 64 to reset by its own elastic force, so that the knocking rod 64 can continuously and stably knock the ring 63 repeatedly, ensuring the continuity and stability of the vibration effect of the vibration mechanism 6.

[0049] See Figure 6 As shown, the exhaust mechanism 8 includes a gear 81 sleeved on the outer wall of the conveying roller 2, an eccentric wheel 82 is meshed on one side of the gear 81, a sleeve 83 is installed on the side wall of the frame 1, and a pull rod 84 is slid inside the sleeve 83, and one end of the pull rod 84 is sleeved on the protrusion of the eccentric wheel 82.

[0050] See Figure 6 As shown, an exhaust pipe 85 is connected between the sleeve 83 and the collecting shell 55, and an air supply pipe 86 is connected between the sleeve 83 and the air storage pipe 71. An intake one-way valve is installed at the connection between the exhaust pipe 85 and the sleeve 83, and an exhaust one-way valve is installed at the connection between the air supply pipe 86 and the sleeve 83 to ensure the orderly flow of gas from the collecting shell 55 to the sleeve 83 and then to the air storage pipe 71.

[0051] See Figures 7 and 8 As shown, the auxiliary mechanism 9 includes a transverse tube 91 installed on the side wall of the frame 1, and a push plate 92 slides inside the transverse tube 91. The push plate 92 passes through one end of the transverse tube 91 and is welded with an extrusion rod 94. The push plate 92 is located below the extrusion rod 94 and is welded with a push block 98.

[0052] See Figures 7 and 8 As shown, the auxiliary mechanism 9 also includes two groups of connecting plates 95 welded to the top of the frame 1, and a baffle 96 is rotatably provided between the two groups of connecting plates 95. The connecting plates 95 and the baffle 96 are rotatably connected by a torsion spring, and a bevel block 97 is installed on the side wall of the baffle 96, and the bevel block 97 and the push block 98 slide together.

[0053] See Figure 8 As shown, a push rod 67 is installed on the side wall of the knocking rod 64, a diaphragm B10 is embedded in the interior of the conveying roller 2, the inner cavity of the conveying roller 2 is filled with hydraulic oil, and the interior of the conveying roller 2 is connected to the horizontal pipe 91 through a connecting pipe.

[0054] See Figure 8 As shown, a spring B93 is provided inside the cross tube 91, and the spring B93 is sleeved on the outer wall of the push plate 92. When the hydraulic oil enters the cross tube 91 and squeezes the push plate 92 to move, the push plate 92 will squeeze the spring B93 to cause it to deform. When the squeezing force of the hydraulic oil weakens or disappears, the spring B93 will rely on its own elastic restoring force to push the push plate 92 to quickly return to its original position.

[0055] Working principle: When food needs to be cooled, the food is first placed on the surface of the conveyor belt 11, and then the motor is started. The motor drives the two sets of conveyor rollers 2 to rotate synchronously. Under the action of the conveyor rollers 2, the food on the surface of the conveyor belt 11 is moved to the inside of the box 3 and enters the cooling area. Then the air cooler 54 is started. The cold air generated by the air cooler 54 is transported to the inside of the shell 52 through the cold air duct 51, and then ejected through the guide port 53 on one side of the shell 52. Since the multiple sets of shells 52 are arranged symmetrically in pairs, the cold air ejected from the symmetrical guide ports 53 will form convection cold air, which directly acts on the food on the surface of the conveyor belt 11 through convection cold air to achieve cooling of the food.

[0056] At the same time, the convective cold air will form an upward wind after docking, and the cooled hot air will enter the interior of the collection shell 55, while a part of the hot air will enter the interior of the air outlet shell 57 through the connecting pipe 56, and then be ejected through the nozzle of the air outlet shell 57 to act on the surface of the food, so that the ejected hot air can dry out the residual moisture on the surface of the food;

[0057] When the conveyor roller 2 is driven by the motor to rotate, the fixed shaft 61 inside the conveyor roller 2 remains stationary because one end is fixed to the outer wall of the frame 1, and the cam 62 sleeved on the surface of the fixed shaft 61 also remains stationary. As the conveyor roller 2 rotates, the collar 63 installed inside the conveyor roller 2 rotates synchronously, and the knocking rod 64 sliding inside the collar 63 will continuously contact the stationary cam 62. Since the cam 62 has a convex structure, during the rotation of the conveyor roller 2, the cam 62 will squeeze the knocking rod 64, causing the knocking rod 64 to slide in the collar 63. When the knocking rod 64 is released from the squeezing of the cam 62, it is reset under the action of the spring A65, causing the knocking rod 64 to continuously knock on the inner wall of the conveyor roller 2 to generate high-frequency slight vibration, and the conveyor roller 2 transmits the generated vibration to the surface of the conveyor belt 11;

[0058] In addition, one end of the vibration rod 66 that is in contact with the side wall of the conveyor roller 2 is simultaneously affected by the vibration, and then transmits the vibration to the middle position of the conveyor belt 11 that is in contact with it. When the food passes over the top of the vibration rod 66, the vibration generated by the conveyor belt 11 causes the food to jump slightly.

[0059] When the conveyor belt 11 rotates, the scraper 74 fits tightly with the conveyor belt 11 and can scrape out the impurities remaining on its surface. At the same time, when the conveyor roller 2 is rotating, the conveyor roller 2 drives the gear 81 to rotate. Since the gear 81 is meshed and connected with the eccentric wheel 82, the gear 81 drives the eccentric wheel 82 to rotate synchronously, so that the eccentric wheel 82 drives the pulling rod 84 to move back and forth inside the sleeve 83 through the eccentric structure, and sucks part of the gas inside the collection shell 55 into the interior of the sleeve 83 through the exhaust pipe 85, and then transports it to the interior of the air storage pipe 71 through the air supply pipe 86 and sprays it out through the nozzle 72. Since the nozzle 72 is designed to be flat, the wind sprayed by the nozzle 72 blows vertically to the surface of the scraper 74, so that the impurities on the surface of the scraper 74 can be blown to the inside of the collection box for storage;

[0060] In addition, when the knocking rod 64 moves back and forth, it synchronously drives the push rod 67 to move. The push rod 67 reciprocates and squeezes the diaphragm B10, causing the diaphragm B10 to squeeze the hydraulic oil in the inner cavity of the conveyor roller 2. The hydraulic oil enters the cross pipe 91 through the connecting pipe, squeezing the push plate 92 to move. The push plate 92 drives the squeezing rod 94 to squeeze the diaphragm A73, thereby increasing the gas pressure in the air storage pipe 71 and making the impact force of the ejected air flow greater. At the same time, when the push plate 92 moves, it drives the push block 98 to move. The push block 98 contacts the inclined block 97 and pushes the baffle 96 to rotate a certain angle, so that the wind ejected from the nozzle 72 blows along the baffle 96 to the side of the conveyor roller 2.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
