Description

Technical Field

[0001] The present invention relates to the technical field of food cooling, and particularly to a heat exchange device for rapid cooling of food. Background Art

[0002] The heat exchange device for rapid cooling of food is applicable to various food processing scenarios. For example, after baked foods (such as bread, cakes, etc.) are taken out of the oven, they need to be rapidly cooled to prevent spoilage, maintain taste and quality. In meat processing, cooked meat products are cooled to extend the shelf life and facilitate packaging and storage. In fruit and vegetable processing, heat-treated fruits and vegetables are cooled in time to lock in nutrients and flavors. In large-scale food production such as fast food and prepared dishes, cooked foods are rapidly cooled for subsequent packaging, transportation and sales, which can efficiently meet the cooling needs of different food production enterprises.

[0003] However, in the existing food cooling technology, most energy-saving heat exchange devices still have problems such as unstable food transportation and discontinuous cooling processes, resulting in low cooling efficiency. Most transportation methods are difficult to ensure the stable and continuous movement of food, and it is easy to have food accumulation and jamming, affecting the cooling progress. At the same time, it is difficult for food to flow smoothly inside the device, and there is a lack of an effective lifting mechanism, making it impossible for food to smoothly transfer from the lower layer to the upper layer for sufficient cooling, resulting in uneven cooling. Moreover, the conveyor belt often runs unstably during the feeding process, and food is prone to jolting and spilling when being sent out, which not only affects production efficiency but may also damage the food.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: As Figures 1-4As shown in the figure, the present invention provides a heat exchange device for rapid cooling of food, which includes a blanking rack 1 and a feeding rack 5. Heat exchange plates 6 are fixedly arranged on both sides of the blanking rack 1 and the feeding rack 5. A conveying mechanism 2 is fixedly arranged on the upper surfaces of the blanking rack 1 and the feeding rack 5 together. Lifting mechanisms 3 are fixedly arranged on the inner walls on both sides of the blanking rack 1 and the feeding rack 5 together. One of the lifting mechanisms 3 is located below the conveying mechanism 2. Feeding mechanisms 4 are fixedly arranged on the lower inner walls of the blanking rack 1 and the feeding rack 5. The conveying mechanism 2 includes a conveying rack 20. The lower surface of the conveying rack 20 is fixedly connected to the upper surfaces of the blanking rack 1 and the feeding rack 5. A sliding rack 27 is fixedly arranged on one inner wall of the conveying rack 20. A conveying motor 25 is fixedly arranged on one side of the conveying rack 20. The output end of the conveying motor 25 is fixedly provided with a conveying driving rod 23. Two conveying driving sprockets 22 are fixedly arranged on the outer side of the conveying driving rod 23. A conveying driven rod 28 is slidably arranged inside the end of the conveying rack 20 far from the conveying motor 25. Two conveying driven sprockets 29 are fixedly arranged on the outer side of the conveying driven rod 28. Each conveying driving sprocket 22 and conveying driven sprocket 29 are jointly sleeved with a conveying chain 26. A plurality of conveying push plates 201 are fixedly arranged on the outer side of the conveying chain 26. Both ends of the conveying driven rod 28 are rotatably sleeved with tension adjusting rods 202. The outer sides of the tension adjusting rods 202 are slidably matched with one side of the conveying rack 20. Two adjusting nuts 203 are threadedly sleeved on the outer sides of the tension adjusting rods 202.

[0029] By adopting the above technical solution, when the conveying motor 25 is started, the output end of the conveying motor 25 drives the conveying driving rod 23 to rotate. The two conveying driving sprockets 22 on the outer side of the conveying driving rod 23 rotate accordingly. The conveying driven sprockets 29 and the conveying driven rod 28 are driven to rotate through the conveying chain 26. The conveying chain 26 starts to move in a cycle. The plurality of conveying push plates 201 fixedly arranged on its outer side push the food to move stably and continuously on the upper surface of the sliding rack 27 between the blanking rack 1 and the feeding rack 5, and send it into the lifting mechanism 3 inside the blanking rack 1 for descending.

Through the conveying mechanism 2, the conveying motor 25 drives the conveying chain 26 and the conveying push plates 201, and the stable and continuous conveying of the food can be realized, which helps to improve the food cooling efficiency.

[0030] Two reinforcing stay ropes 7 are fixedly arranged on both sides of the blanking rack 1 and the feeding rack 5.

[0031] By adopting the above technical solution, two reinforcing stay ropes 7 are fixedly arranged on both sides of the blanking rack 1 and the loading rack 5.

[0035] By adopting the above technical solution, one end of the conveying rack 20 is fixedly provided with two conveying limit racks 21, and the inner side of the conveying limit racks 21 is rotatably connected to one end of the conveying driving rod 23. The conveying limit racks 21 can limit the conveying driving rod 23, prevent axial displacement of the conveying driving rod 23 during rotation, ensure the stable rotation of the conveying driving rod 23, and then ensure the normal operation of the conveying chain 26 and the conveying push plate 201, and improve the stability of food conveying.

[0036] Working principle: Start the conveying motor 25. The output end of the conveying motor 25 drives the conveying driving rod 23 to rotate. The two conveying driving sprockets 22 on the outer side of the conveying driving rod 23 rotate accordingly. The conveying driven sprocket 29 and the conveying driven rod 28 are driven to rotate through the conveying chain 26. The conveying chain 26 starts to move in a cycle. The multiple conveying push plates 201 fixed on its outer side push the food to move stably and continuously on the upper surface of the sliding rack 27 between the blanking rack 1 and the loading rack 5, and send it into the lifting mechanism 3 inside the blanking rack 1 for descending, and then cooperate with the feeding mechanism 4 below to send out the cooled food, realizing the conveying of food; when it is necessary to adjust the tension of the conveying chain 26, the two adjusting nuts 203 on the outer side of the tension adjusting rod 202 can be loosened, the tension adjusting rod 202 is moved to a suitable position, and then the adjusting nuts 203 are tightened for fixation.

[0037] Embodiment 2: As Figures 5-6As shown in the figure, the lifting mechanism 3 includes two transmission motors 31 which are fixedly connected to the upper surface of the blanking frame 1. A transmission rod 32 is fixedly provided on one side of the two transmission motors 31. A lifting motor 30 is fixedly provided on one side of one of the transmission motors 31.

One ends of two of the lifting rotating rods 37 are respectively fixedly connected to the output ends of the two transmission motors 31. A plurality of lifting driving sprockets 36 are fixedly provided on the outer sides of two of the lifting rotating rods 37. A plurality of lifting driven sprockets 34 are fixedly provided on the outer sides of the other two lifting rotating rods 37.

A plurality of lifting plates 38 which are evenly distributed at equal intervals are fixedly provided on the outer sides of the lifting chains 35 on the same side.

[0038] By adopting the above technical solution, when the lifting motor 30 is started, the lifting motor 30 drives one of the transmission motors 31 to work, and the other transmission motor 31 works synchronously through the transmission rod 32. The output ends of the two transmission motors 31 respectively drive the two lifting rotating rods 37 to rotate. The lifting driving sprockets 36 on the outer sides of the two lifting rotating rods 37 rotate accordingly. The lifting driven sprockets 34 and the other two lifting rotating rods 37 are driven to rotate through the lifting chain 35. The plurality of lifting plates 38 fixedly provided on the outer sides of the lifting chains 35 on the same side start to move in a cycle, lifting the food from the lower layer to the upper layer, facilitating the flow and cooling treatment of the food in the equipment. The lifting mechanism 3 inside the blanking frame 1 is used for the descent of the food, and the lifting mechanism 3 inside the loading frame 5 is used for the lifting of the food. Through the lifting mechanism 3, by using the lifting motor 30 to drive the lifting chain 35 and the lifting plates 38, the food can be lifted from the lower layer to the upper layer, facilitating the flow and cooling treatment of the food in the equipment.

[0039] A plurality of lifting limit frames 33 are fixedly provided on the upper and lower surfaces of the blanking frame 1 and the loading frame 5. The inner sides of the lifting limit frames 33 are rotatably connected to the lifting rotating rods 37.

[0040] By adopting the above technical solution, a plurality of lifting limit frames 33 are fixedly provided on the upper and lower surfaces of the blanking frame 1 and the loading frame 5. The inner sides of the lifting limit frames 33 are rotatably connected to the lifting rotating rods 37. The lifting limit frames 33 play a role in limiting and supporting the lifting rotating rods 37, ensuring the stability of the lifting rotating rods 37 during the rotation process, preventing the lifting rotating rods 37 from shaking or shifting, ensuring the normal operation of the lifting chain 35 and the lifting plates 38, and enabling the food to be lifted and transferred smoothly.

[0041] Working principle: When the heat exchange plate 6 is working, the internal temperatures of the blanking rack 1 and the loading rack 5 will decrease accordingly. Subsequently, the lifting motor 30 can be started. The lifting motor 30 drives one of the transmission mechanisms 31 to work. Through the transmission rod 32, the other transmission mechanism 31 works synchronously. The output ends of the two transmission mechanisms 31 respectively drive the two lifting rotating rods 37 to rotate. The lifting drive sprockets 36 on the outer sides of the two lifting rotating rods 37 rotate accordingly. Through the lifting chain 35, the lifting driven sprockets 34 and the other two lifting rotating rods 37 are driven to rotate. A plurality of lifting plates 38 fixedly connected together on the outer sides of the same-side lifting chains 35 start to move cyclically, lifting the food from the lower layer to the upper layer, facilitating the flow and cooling treatment of the food in the equipment. The lifting mechanism 3 inside the blanking rack 1 is used for the descent of the food, and the lifting mechanism 3 inside the loading rack 5 is used for the lifting of the food.

[0042] Embodiment 3: As Figures 7-8 shown, the feeding mechanism 4 includes a moving rack 40. The two sides of the moving rack 40 are fixedly connected to the lower end of the blanking rack 1.

Two moving driven wheels 47 are fixedly provided on the outer side of the moving driven rod 48. The moving driven wheels 47 are in sliding contact with the inner side of the moving conveyor belt 46.

[0043] By adopting the above technical solution, when the moving motor 42 is started, the output end of the moving motor 42 drives the moving drive rod 44 to rotate. The two moving drive wheels 45 on the outer side of the moving drive rod 44 rotate accordingly. Through the moving conveyor belt 46, the moving driven wheels 47 and the moving driven rod 48 are driven to rotate. The moving conveyor belt 46 starts to move cyclically, realizing the smooth delivery of the food; a plurality of supporting brackets 41 rotatably provided on the inner walls of the two sides of the moving rack 40 play a supporting role for the moving conveyor belt 46, ensuring its stable operation. Through the feeding mechanism 4, the smooth delivery of the food is realized, and the stability of the operation of the moving conveyor belt 46 can be ensured. The three mechanisms work together, effectively improving the overall performance and efficiency of the food rapid cooling heat exchange equipment.

[0044] A plurality of supporting brackets 41 arranged at equal intervals are rotatably provided on the inner walls of the two sides of the moving rack 40. The outer sides of the supporting brackets 41 are in sliding contact with the lower surface of the moving conveyor belt 46.

[0047] By adopting the above technical solution, one end of the moving frame 40 is fixedly provided with a moving mounting frame 43, and one side of the moving mounting frame 43 is fixedly fitted with a moving motor 42.
