Description

Technical Field

[0001] The present invention relates to the technical field of food quick-freezing, and specifically to an efficient circulating air control device for food quick-freezing. Background Art

[0002] An efficient circulating air control device for food quick-freezing is a device designed to improve the air circulation efficiency during the quick-freezing process of food. It uses a high-efficiency centrifugal fan or axial flow fan to provide a strong and stable air flow, and allows precise adjustment of the wind speed to control the air circulation to adapt to different freezing requirements, so as to achieve efficient circulation of cold air in the quick-freezing equipment, enabling the food to be quickly and evenly frozen, and ensuring the quality and nutrition of the food.

[0003] When the food is transported to the efficient circulating air control device through the conveying mechanism, most of the food will be in a stacked state. As a result, the quick-freezing quality of the food will be affected. In the prior art, manual labor is used to flatten the stacked food. However, the manual operation speed is relatively slow. Especially when dealing with a large amount of food, it takes a lot of time and manpower, affecting the overall production efficiency. Moreover, hiring workers to perform the food flattening operation will increase the labor cost, and as the labor cost continues to rise, this cost will further increase. During the manual operation process, the contact of personnel will increase the risk of food contamination, making it difficult to ensure food hygiene and safety. Long-term repetitive labor will make workers feel fatigued, affecting the work quality and efficiency, and even causing workers to be injured.

[0004] After the efficient circulating air control device has been used for a long time, the air filtration medium inside it will become saturated by adsorption. After the filtration medium becomes saturated by adsorption, it cannot effectively filter pollutants such as impurities, dust, and microorganisms in the air, resulting in a deterioration of the air quality in the quick-freezing environment. This will increase the risk of food contamination, affecting the quality and safety of the food. In the prior art, it is necessary to disassemble the device to replace the filtration medium. The operation process is relatively cumbersome, requiring a lot of time and manpower. When disassembling the device for replacement, the equipment needs to stop running, which will cause the air purification process to be interrupted, affecting the indoor air quality. Frequent disassembly of the device will cause wear or damage to the components of the equipment, affecting the service life and stability of the equipment. During the disassembly and installation process, external pollutants will enter the interior of the device, having an adverse effect on the filtration effect. Due to reasons such as complex operation and easy damage of the equipment, the maintenance cost will increase, including labor costs, component replacement costs, etc. The equipment shutdown for filtration medium replacement will affect the normal progress of related work and reduce the overall work efficiency.

[0005] Therefore, an efficient circulating air control device for food quick-freezing is proposed to solve the above problems. Summary of the Invention

[0017] Compared with the prior art, the present invention provides an efficient circulating air control device for quick-freezing food materials, having the following beneficial effects:

[0018] 1. Through the mutual cooperation among the first cylinder, the second direction converter and the roller in the auxiliary quick-freezing mechanism, the surface of the food material can be rolled to adsorb the moisture on the surface of the food material. Reducing the moisture on the surface of the food material can accelerate the freezing speed, enabling the food material to pass through the ice crystal formation zone faster, reducing the damage of ice crystals to the cells of the food material, and thus better maintaining the quality and taste of the food material. When there is too much moisture on the surface of the food material, large ice crystals are likely to form during the freezing process. These ice crystals will damage the cell structure of the food material, resulting in the loss of nutrients and a deterioration in taste. By adsorbing the surface moisture, the formation and growth of ice crystals can be reduced, mitigating the damage to the food material. Removing the moisture on the surface of the food material can reduce the viscosity between the food materials, reduce the situation of food materials sticking to each other during the quick-freezing process, facilitate subsequent processing and packaging. Reducing the moisture on the surface of the food material helps to reduce the growth and reproduction conditions of microorganisms, extend the shelf life of the food material, and improve the storage stability. Adsorbing the moisture on the surface of the food material can make the surface of the food material drier, the appearance cleaner, and improve the market competitiveness of the product.

[0019] 2. By means of the baffle in the auxiliary quick-freezing mechanism, the stacked food materials can be laid flat and arranged neatly. The baffle can quickly lay flat and arrange a large number of food materials, greatly improving work efficiency, saving time and labor costs. The baffle can ensure that the laying flat and arrangement of each batch of food materials have high consistency, enabling the food materials to be processed more uniformly in subsequent processing or handling processes, ensuring the quality stability of the products. Manual laying flat is affected by factors such as operator fatigue and inattention, resulting in inconsistent laying flat and arrangement effects. The baffle operation can reduce the errors caused by these human factors and improve the accuracy of work. Manually laying flat food materials is a relatively cumbersome and laborious task. Long-term operation can cause worker fatigue and injuries. Using the baffle can reduce the labor intensity of workers and lower the risk of occupational diseases. Laying flat and arranging the food materials neatly can make more effective use of space, improving the space utilization rate of storage or processing sites. The neatly laid flat and arranged food materials are more convenient for subsequent quick-freezing, packaging, transportation and other operations, improving the fluency of the entire production process.

[0020] 3. Through the T-shaped push rod in the auxiliary filtering mechanism, the filter medium in the high-efficiency circulating air control device can be quickly pushed out, avoiding opening the high-efficiency circulating air control device. The method of using the T-shaped push rod to push the filter medium is relatively simple and does not require complex disassembly steps, which can reduce the complexity and difficulty of operation. This method can complete the replacement of the filter medium faster, improve work efficiency, reduce equipment downtime, avoid problems such as component damage or connection loosening caused by frequent disassembly of the device, and reduce the risk of equipment failure due to disassembly and installation. During the process of replacing the filter medium, it is not necessary to completely disassemble the device, which helps to maintain the sealing performance of the device and reduce the possibility of external pollutants entering. Compared with the cumbersome disassembly and installation work, the operation of using the T-shaped push rod to push the filter medium is relatively easy, reducing the labor intensity of the staff.

[0033] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0034] Embodiment

[0035] Please refer to Figures 1 to 4 as shown in

[0036] To solve the problems mentioned in the technical solutions, the embodiment of the present application provides an efficient circulating air control device for quick-freezing food ingredients, which is used for quick-freezing food ingredients and includes: a base 1, a feeder 2 fixedly connected to the top surface of the base 1, two first support plates 3 fixedly connected to the top surface of the base 1, a conveyor belt 4 drivingly connected between the two first support plates 3, a quick freezer 5 fixedly connected to the top surface of the base 1, an auxiliary quick-freezing mechanism for assisting in quick-freezing food ingredients is arranged on the top inner wall of the quick freezer 5, and an auxiliary filtering mechanism for quickly replacing the filtering medium is arranged on the top surface of the quick freezer 5;

[0037] The auxiliary quick-freezing mechanism includes two connecting blocks 601, and a rotating rod 602 for driving auxiliary quick-freezing is rotatably connected through between the two connecting blocks 601;

[0038] The auxiliary quick-freezing mechanism further includes a wedge-shaped push block 603. The two connecting blocks 601 are fixedly connected to the top surface of the inner wall of the quick-freezer 5. The wedge-shaped push block 603 is fixedly connected to the outer surface of the rotating rod 602. One end of the rotating rod 602 is fixedly connected to a first direction converter 604. The end of the first direction converter 604 away from the rotating rod 602 is fixedly connected to a first cylinder 608. The bottom surface of the connecting block 601 is fixedly connected to a telescopic rod 606. The bottom surface of the telescopic rod 606 is fixedly connected to an n-shaped auxiliary block 605. A first return spring 607 is fixedly connected between the n-shaped auxiliary block 605 and the connecting block 601.

[0039] The top surface of the n-shaped auxiliary block 605 is fixedly connected to an auxiliary plate 613. The top surface of the auxiliary plate 613 is rotatably connected to a rotating block 614. The inner wall of the n-shaped auxiliary block 605 is rotatably connected to a second direction converter 609. The end of the second direction converter 609 away from the first cylinder 608 is fixedly connected to a roller 610, and the roller 610 is located inside the n-shaped auxiliary block 605. The top surface of the base 1 is fixedly connected to a second support plate 612. The top surface of the second support plate 612 is fixedly connected to a baffle 611.

[0040] Wherein: The inside of the feeder 2 is in an inclined state, mainly used for placing food materials on the surface of the conveyor belt 4. The conveyor belt 4 is made of water-absorbing material. The motor drives the conveyor belt 4 and the rotating rod 602 to rotate simultaneously. A number of partition blocks are arranged on the side of the bottom surface of the baffle 611 close to the quick-freezer 5, and exactly one food material can pass through between every two partition blocks.

[0041] In the prior art, when the food is transported to the high-efficiency circulating air control device through the conveying mechanism, most of the food will be in a stacked state, which will affect the quick-freezing quality of the food. In the prior art, the stacked food is spread out manually, and the manual operation speed is relatively slow. Especially when processing a large amount of food, it takes a lot of time and manpower, which affects the overall production efficiency. Hiring workers to spread the food will increase the labor cost, and as the labor cost continues to rise, this cost will increase further. During the manual operation, the contact of people will increase the risk of food contamination, making it difficult to ensure the hygiene and safety of food. Long-term repetitive labor will make workers feel tired, which will affect the work quality and efficiency and even cause injuries to workers. Compared with the prior art, the baffle 611 in the auxiliary quick-freezing mechanism can be used to spread the stacked food and arrange the food neatly. The baffle 611 can quickly spread and arrange a large amount of food. It greatly improves work efficiency, saves time and labor costs. Baffle 611 can ensure that the paving and arrangement of each batch of ingredients are highly consistent, so that the ingredients can be processed more evenly during subsequent processing or handling, ensuring the quality stability of the product. Manual paving will be affected by factors such as operator fatigue and lack of concentration, resulting in inconsistent paving and arrangement effects. The operation of baffle 611 can reduce the errors caused by these human factors and improve work accuracy. Manual paving of ingredients is a relatively tedious and tiring job. Long-term operation will cause worker fatigue and injury. The use of baffle 611 can reduce the labor intensity of workers and reduce the risk of occupational diseases. Neatly paving and arranging ingredients can make more effective use of space and improve the space utilization rate of storage or processing sites. Neatly paved and arranged ingredients are more convenient for subsequent quick freezing, packaging, transportation and other operations, improving the smoothness of the entire production process.

[0042] For further examples, please refer to Figures 5 to 7 As shown:

[0043] The auxiliary filtering mechanism includes an outer frame 702, and a filter plate 711 for filtering air is slidably connected inside the outer frame 702;

[0044] The auxiliary filtering mechanism also includes an exhaust duct 701, which passes through and is fixedly connected to the top surface of the quick freezer 5, an outer frame 702 is fixedly connected to a side of the exhaust duct 701 away from the quick freezer 5, an air inlet duct 715 is fixedly connected to the top surface of the outer frame 702, a connecting column 703 is fixedly connected to the side of the outer frame 702, and a connecting plate 704 is fixedly connected to the end of the connecting column 703 away from the outer frame 702.

[0045] A T-shaped push rod 705 is slidably connected through the inside of the connecting plate 704, and the T-shaped push rod 705 is slidably connected inside the outer frame 702. One side of the outer frame 702 close to the connecting plate 704 is fixedly connected with a support rod 706. One end of the T-shaped push rod 705 away from the outer frame 702 is rotatably connected with a connecting rod 707. The top surface of the outer frame 702 is fixedly connected with an alarm 710.

[0046] A gasket 708 is fixedly connected to the outer surface of the T-shaped push rod 705, and the gasket 708 is located between the connecting plate 704 and the outer frame 702. A second return spring 709 is fixedly connected between the gasket 708 and the outer frame 702. A third support plate 712 is slidably connected inside the outer frame 702. A third return spring 713 is fixedly connected between the third support plate 712 and the outer frame 702. A contact 714 is fixedly connected to the bottom surface of the inner wall of the outer frame 702.

[0047] Wherein: the contact 714 is electrically connected to the alarm 710, and the filter plate 711 is made of ultra-fine glass fiber material.

[0048] In the prior art, after the high-efficiency circulating air control device has been used for a long time, the air filtration medium inside it will be saturated by adsorption. After the filtration medium is saturated by adsorption, it cannot effectively filter pollutants such as impurities, dust, and microorganisms in the air, resulting in a deterioration of the air quality in the quick-freezing environment. This will increase the risk of food ingredients being contaminated and affect the quality and safety of food ingredients. In the prior art, it is necessary to disassemble the device to replace the filtration medium. The operation process is relatively cumbersome and requires a lot of time and manpower. When disassembling the device for replacement, the equipment needs to stop running, which will cause the air purification process to be interrupted and affect the indoor air quality. Frequent disassembly of the device will cause wear or damage to the components of the equipment, affecting the service life and stability of the equipment. During the disassembly and installation process, external pollutants will enter the inside of the device, having an adverse effect on the filtration effect. Due to reasons such as complex operation and easy damage of the equipment, the maintenance cost will increase, including labor costs, component replacement costs, etc. The equipment downtime for replacing the filtration medium will affect the normal progress of related work and reduce the overall work efficiency. Compared with the prior art, through the T-shaped push rod 705 in the auxiliary filtration mechanism, the filtration medium in the high-efficiency circulating air control device is quickly pushed out, avoiding opening the high-efficiency circulating air control device. The method of using the T-shaped push rod 705 to push the filtration medium is relatively simple and does not require complex disassembly steps, which can reduce the complexity and difficulty of the operation. This method can complete the replacement of the filtration medium faster, improve work efficiency, reduce equipment downtime, avoid problems such as component damage or connection loosening caused by frequent disassembly of the device, and reduce the risk of equipment failure due to disassembly and installation. During the process of replacing the filtration medium, it is not necessary to completely disassemble the device, which helps to maintain the sealing performance of the device and reduce the possibility of external pollutants entering. Compared with the cumbersome disassembly and installation work, the operation of using the T-shaped push rod 705 to push the filtration medium is relatively easy, reducing the labor intensity of the staff.

[0049] The working principle of all the contents in the above embodiments is as follows:

[0050] In the initial state: The third support plate 712 is located above the contact 714.

[0051] The following is the working process of the auxiliary quick-freezing mechanism for wiping the surface moisture of food ingredients:

[0052] When in use, the food to be quick-frozen is placed on the surface of the conveyor belt 4 through the inclined surface of the dispenser 2, and then the motor drives the conveyor belt 4 to rotate. The rotation of the conveyor belt 4 can transport the food on its surface into the quick freezer 5 for quick freezing. In the prior art, the moisture on the surface of the food is not completely removed before the food is quick-frozen, and the moisture on the surface of the food is easy to freeze quickly during the quick freezing process to form larger ice crystals. The large ice crystals will destroy the cell structure of the food, resulting in a deterioration in the texture of the food, a poor taste, and possible loss of nutrients. Food with moisture requires more energy to freeze the moisture during freezing, which will increase the operating cost of the freezing equipment. The surface moisture may cause the food to stick to each other, resulting in uneven freezing. During the process of transporting the food for quick freezing by the conveyor belt 4, it will pass through the baffle 611, and the stacked food will be flattened by the blocking of the baffle 611, and a plurality of partition blocks are slidably connected to the bottom surface of the baffle 611 close to the quick freezer 5. The partition blocks can be adjusted at intervals according to the different sizes of the food, so that every two partition blocks Just one ingredient can pass through between them, and then the ingredients can be sorted, laid out and arranged, which greatly improves work efficiency and saves time and labor costs. The baffle 611 can ensure that the laying and arrangement of each batch of ingredients are highly consistent, so that the ingredients can be processed more evenly in the subsequent processing or handling process, ensuring the quality stability of the product. Manual laying will be affected by factors such as fatigue and lack of concentration of the operator, resulting in inconsistent laying and arrangement effects, and the operation of the baffle 611 can reduce the errors caused by these human factors and improve the accuracy of the work. Manual laying of ingredients is a relatively tedious and tiring job, and long-term operation will cause fatigue and injury to workers. The use of the baffle 611 can reduce the labor intensity of workers and reduce the risk of occupational diseases. Tiling and arranging ingredients neatly can make more effective use of space and improve the space utilization rate of storage or processing sites. Neatly laid and arranged ingredients are more convenient for subsequent quick freezing, packaging, transportation and other operations, improving the fluency of the entire production process.

[0053] Meanwhile, the motor drives the rotating rod 602 to rotate. The rotation of the rotating rod 602 drives the wedge-shaped push block 603 fixedly connected thereto to rotate together. The rotation of the wedge-shaped push block 603 pushes the rotating block 614 to move downward. The downward movement of the rotating block 614 drives the auxiliary plate 613 rotatably connected thereto to move downward together. The downward movement of the auxiliary plate 613 drives the n-shaped auxiliary block 605 fixedly connected thereto to move downward together, thereby driving the roller 610 to move downward together. At the same time as the rotating rod 602 rotates, it drives the first direction converter 604 fixedly connected thereto to rotate together. The rotation of the first direction converter 604 drives the first cylinder 608 fixedly connected thereto to rotate. The rotation of the first cylinder 608 drives the second direction converter 609 slidably connected thereto to rotate together. The rotation of the second direction converter 609 drives the roller 610 fixedly connected thereto to rotate, thereby rolling and pressing the food ingredients on the surface of the conveyor belt 4 to adsorb the moisture on the surface of the food ingredients. Reducing the moisture on the surface of the food ingredients can accelerate the freezing speed, enabling the food ingredients to pass through the ice crystal formation zone (referring to a specific area with a temperature range of approximately -1°C to -5°C during the food freezing process) faster, reducing the damage of ice crystals to the food ingredient cells, and thus better maintaining the quality and taste of the food ingredients. When there is too much moisture on the surface of the food ingredients, large ice crystals are likely to form during the freezing process. These ice crystals will damage the cell structure of the food ingredients, resulting in the loss of nutrients and a deterioration in taste. By adsorbing the surface moisture, the formation and growth of ice crystals can be reduced, and the damage to the food ingredients can be alleviated. Removing the moisture on the surface of the food ingredients can reduce the stickiness between the food ingredients, reduce the situation of the food ingredients sticking to each other during the quick-freezing process, facilitate subsequent processing and packaging. Reducing the moisture on the surface of the food ingredients helps to reduce the growth and reproduction conditions of microorganisms, extend the shelf life of the food ingredients, and improve the storage stability. Adsorbing the moisture on the surface of the food ingredients can make the surface of the food ingredients drier, the appearance cleaner, and improve the market competitiveness of the product. Using a cam mechanism to move the roller 610 up and down can make the roller 610 come into dynamic contact with the surface of the food ingredients instead of continuously pressing on the food ingredients. The intermittent contact can reduce the heat transfer between the roller 610 and the food ingredients, which is beneficial to maintaining a low-temperature environment.

[0054] Please refer to the above working process Figures 1 to 4 。

[0055] The following is the working process of the auxiliary filtration mechanism for replacing the filter medium:

[0056] During use, after the filter plate 711 has been used for a long time, since the filter plate 711 is made of ultra-fine glass fiber and forms a complex maze structure through the gaps between the fibers, it can capture particles of various sizes, thereby filtering the particulate matter in the air. After long-term use, its weight will gradually increase due to adsorbed impurities. When the filter plate 711 is saturated with adsorption, the filter plate 711 will press the third support plate 712 to move downward, thereby squeezing the third return spring 713 to compress. Immediately afterwards, the third support plate 712 touches the contact 714. Since the contact 714 is electrically connected to the alarm 710, that is, the contact 714 triggers the alarm 710 to sound an alarm, thereby reminding the staff to replace the filter plate 711. By touching the contact 714 to alarm and remind the staff, the method of touching the contact 714 to alarm is relatively simple, does not require complex equipment and technical support, and is easy to implement and operate. Compared with the method of detecting the saturation degree of the filter plate 711 by a sensor and then alarming, the method of touching the contact 714 to alarm has a lower cost, can save equipment investment and maintenance costs. The method of touching the contact 714 to alarm relies on physical contact, has a higher reliability, and is not prone to false alarm situations;

[0057] When replacing the filter plate 711, the staff first place a new filter plate 711 inside the outer frame 702. Subsequently, hold the end of the connecting rod 707 away from the T-shaped push rod 705 and pull it in the direction away from the connecting plate 704 with the fixed point of the support rod 706 as the fulcrum. At this time, the connecting rod 707 makes a lever movement on the support rod 706. Since the arm of force of the connecting rod 707 away from the T-shaped push rod 705 is longer than the arm of force close to the T-shaped push rod 705, it is a labor-saving lever at this time. The labor-saving lever includes: the support rod 706 and the connecting rod 707, and the other end of the connecting rod 707 is rotatably connected to the T-shaped push rod 705. Due to the lever principle, the staff can use a smaller force to push the T-shaped push rod 705, so that the T-shaped push rod 705 slides inside the outer frame 702, and the new filter plate 711 is pushed to move by the T-shaped push rod 705, thereby replacing the adsorption-saturated filter plate 711 with the new filter plate 711, enabling the filter medium to filter air normally. By using the T-shaped push rod 705 to push the new filter plate 711 for replacement, the filter medium inside the high-efficiency circulating air control device can be quickly pushed out, avoiding opening the high-efficiency circulating air control device. The method of using the T-shaped push rod 705 to push the filter medium is relatively simple and does not require complex disassembly steps, which can reduce the complexity and difficulty of the operation. This method can complete the replacement of the filter medium faster, improve work efficiency, reduce equipment downtime, avoid problems such as component damage or connection loosening caused by frequent disassembly of the device, and reduce the risk of device failure due to disassembly and installation. During the process of replacing the filter medium, it is not necessary to completely disassemble the device, which helps to maintain the sealing performance of the device and reduce the possibility of external pollutants entering. Compared with the cumbersome disassembly and installation work, the operation of using the T-shaped push rod 705 to push the filter medium is relatively easy, reducing the labor intensity of the staff.
