Description

Technical Field

[0001] The present invention relates to the technical field of quick-freezing processing, and particularly to a high-efficiency spiral food quick-freezer. Background Art

[0002] The double-screw food quick-freezer is a processing device that can freeze the central temperature of quick-frozen food to below minus 18 degrees Celsius within a short time to reduce the loss of nutrients and retain its original flavor. However, during the operation of the double-screw quick-freezer, frost condensation is likely to occur in its condensation heat exchange part, which not only affects the heat exchange efficiency but also seriously affects the speed efficiency of food. The reason for frost condensation is often that the surface temperature of the heat exchange tubes of the condenser drops to a certain degree, usually below zero degree Celsius, and at this time, the moisture in the air may condense into frost on the heat exchange tubes.

[0003] For example, the high-efficiency and energy-saving double-screw quick-freezer for large-scale food quick-freezing described in the application number 202410426547.1 defrosts the thick frost condensed on the surface of the spiral heat exchange tubes by using an automated mechanical defrosting method. Driven by a transmission component, multiple groups of movable brush plates perform reciprocating defrosting on the surface of the spiral heat exchange tubes, directly acting on the frost layer on the surface of the heat exchange tubes to separate and fall off from the heat exchange tubes. Moreover, the fallen frost is stored using a water storage plate, and an electric heating plate is used for defrosting operation.

[0004] Based on the retrieval of the above information, it can be seen that when the existing multiple groups of movable brush plates are used to wipe and defrost the surface of the spiral heat exchange tubes, the multi-layer movable brush plates overlap vertically in the vertical direction, and the wiped-off frost is likely to directly fall on the movable brush plates. Since the distance from the heat exchange tubes is relatively close, it is easy to exacerbate the frost condensation on the surface of the heat exchange tubes. And after the wiped-off frost falls into the water storage plate, the electric heating plate is used for heating and defrosting. At this time, in order to avoid the interference of the fallen frost on the heat exchange tubes, the electric heating plate often needs to be kept on, resulting in serious waste of electric energy. Therefore, a high-efficiency spiral food quick-freezer is specifically proposed to sequentially wipe off the frost on the spiral heat exchange tubes, ensure that the wiped-off frost can effectively fall, stay away from the spiral heat exchange tubes, and further avoid the interference of the fallen frost on the spiral heat exchange tubes by means of aggregating and isolating the storage of the fallen frost, and melt the aggregated fallen frost by means of periodic heating, effectively reducing the electric energy consumption. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency spiral food quick-freezer, which solves the problems that when the existing multiple groups of movable brush plates are used to wipe and defrost the surface of the spiral heat exchange tubes, the wiped-off frost is likely to directly fall on the movable brush plates. Since the distance from the heat exchange tubes is relatively close, it is easy to exacerbate the frost condensation on the surface of the heat exchange tubes, and in order to avoid the interference of the fallen frost on the heat exchange tubes, real-time electric heating defrosting needs to be carried out on the fallen frost, resulting in serious waste of electric energy.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention

[0050] Please refer to Figures 1 to 12 , the embodiments of the present invention provide the following technical solutions

[0051] Embodiment 1

[0052] A high-efficiency spiral food quick-freezing machine, comprising a processing chamber 1, a condensation component 2 arranged in the processing chamber 1, and two mutually cooperating spiral conveyors 3. An evaporator 4 is sleeved around the outer perimeters of the two spiral conveyors 3. The evaporator 4 is used to absorb the heat of the food for quick-freezing the food. The condensation component 2 is arranged between the two spiral conveyors 3 and outside the evaporator 4, and is used for cooling and liquefying the refrigerant vapor. The feeding end of one spiral conveyor 3 sequentially passes through the evaporator 4 and the processing chamber 1 and extends to one side of the processing chamber 1 as the food loading station. The discharging end of the other spiral conveyor 3 sequentially passes through the evaporator 4 and the processing chamber 1 and extends to the other side of the processing chamber 1 as the quick-frozen food discharging station. The food to be processed is placed at the food loading station, and the food to be processed is conveyed by the spiral conveyor 3 into the processing chamber 1 and then into the evaporator 4 for quick-freezing, and then the quick-frozen food is taken out through the quick-frozen food discharging station.

[0053] As a detailed description, the condensation component 2 includes a box body 201. Inside the box body 201, a heat exchange chamber 202 and an isolation chamber 203 are sequentially arranged at intervals from top to bottom. A heat exchange component 204 is fixedly installed between the two sides of the inner cavity of the heat exchange chamber 202. Specifically, the heat exchange component 204 includes two mounting shells 2041. A spiral heat exchange tube 2042 is penetrated and fixedly installed between the opposite sides of the two mounting shells 2041. The spiral heat exchange tube 2042 is composed of a plurality of straight pipe segments and elbows. The elbows are placed inside the mounting shells 2041, and the plurality of straight pipe segments are distributed in a matrix between the two mounting shells 2041. The two mounting shells 2041 are respectively fixedly installed on the two sides of the inner cavity of the heat exchange chamber 202. The top and bottom of one side of the box body 201 are respectively penetrated and fixedly installed with an air inlet pipe 206 and an air outlet pipe 207. One ends of the air inlet pipe 206 and the air outlet pipe 207 both extend into the interior of the same mounting shell 2041 and are respectively communicated with the two ends of the spiral heat exchange tube 2042. Further explanation, the air inlet pipe 206 is connected to the refrigerant vapor outlet of the evaporator 4 through a compressor, and the air outlet pipe 207 is connected to the refrigerant inlet of the evaporator 4 through a throttle valve. During use, the refrigerant in the evaporator 4 absorbs the heat of the food to form refrigerant vapor, which is compressed by the compressor and then enters the spiral heat exchange tube 2042 from the air inlet pipe 206. After heat exchange and condensation with the outside air, it is discharged from the air outlet pipe 207, and after being decompressed by the throttle valve, it flows back into the evaporator 4.

[0054] As a preferred solution, in order to achieve the defrosting treatment of the spiral heat exchange tube 2042, a defrosting component 5 is arranged inside the heat exchange cavity 202. Among them, the defrosting component 5 includes a first cleaning plate 501, a second cleaning plate 502, and a plurality of third cleaning plates 503. The first cleaning plate 501, the plurality of third cleaning plates 503, and the second cleaning plate 502 are arranged vertically and are respectively arranged on the upper and lower sides of several straight pipe sections of the spiral heat exchange tube 2042. A plurality of silicone rubber defrosting blocks 504 are fixedly installed at the bottom of the first cleaning plate 501, the top of the second cleaning plate 502, and the top and bottom of the plurality of third cleaning plates 503. The silicone rubber defrosting blocks 504 are in sliding contact with the outer surface of the spiral heat exchange tube 2042. There is an initial frictional force between the silicone rubber defrosting blocks 504 and the spiral heat exchange tube 2042, so as to facilitate defrosting the surface of the spiral heat exchange tube 2042. By using the silicone rubber defrosting blocks 504 to move back and forth on the surface of the spiral heat exchange tube 2042, the defrosting treatment can be achieved. A plurality of load-reducing grooves 505 are opened on both sides of the first cleaning plate 501, the second cleaning plate 502, and the plurality of third cleaning plates 503. A first sliding rod 506 is installed through and slidably between two adjacent horizontally arranged load-reducing grooves 505 in the first cleaning plate 501 and the plurality of third cleaning plates 503. First limiting plates 507 are fixedly installed at both ends of the first sliding rod 506. Second springs 508 are sleeved at both ends of the first sliding rod 506. The two ends of the second spring 508 are respectively in contact with the first limiting plate 507 and the opposite side of the load-reducing groove 505. A second sliding rod 5011 is installed through and slidably between two adjacent horizontally arranged load-reducing grooves 505 in the second cleaning plate 502 and the plurality of third cleaning plates 503. Second limiting plates 5012 are fixedly installed at both ends of the second sliding rod 5011. Third springs 509 are sleeved at both ends of the second sliding rod 5011. The two ends of the third spring 509 are respectively in contact with the second limiting plate 5012 and the opposite side of the load-reducing groove 505. Adjacent two first limiting plates 507 in the vertical direction are fixed by a first connecting plate 5010, and a plurality of first connecting plates 5010 are arranged at intervals. Adjacent two second limiting plates 5012 in the vertical direction are fixed by a second connecting plate 5013, and a plurality of second connecting plates 5013 are arranged at intervals.

[0055] As a detailed description, the second springs 508 and the third springs 509 are used to transmit the traction force between the first cleaning plate 501, the second cleaning plate 502, and the plurality of third cleaning plates 503. Cooperating with the frictional force between the silicone rubber defrosting blocks 504 and the spiral heat exchange tube 2042, during the movement of the first cleaning plate 501, the plurality of third cleaning plates 503, and the second cleaning plate 502, they can be distributed in a stepped shape to ensure that the frost falls smoothly to the bottom of the inner cavity of the heat exchange cavity 202.

[0056] As a preferred solution, in order to achieve the automatic processing of frost condensation, a reciprocating drive assembly 7 is provided at the top of the box body 201. The reciprocating drive assembly 7 includes a servo motor 701. The output end of the servo motor 701 is fixedly connected with a reciprocating lead screw 702 through a coupling. A moving plate 703 which is used in cooperation is sleeved on the outer periphery of the reciprocating lead screw 702. In order to ensure the stable movement of the moving plate 703, the servo motor 701 is fixedly installed on one side of the box body 201 through a fixing plate. Ear plates 704 are fixedly installed on the front and rear sides of both sides of the top of the box body 201. An auxiliary rod 705 is fixedly installed between the opposite sides of the two ear plates 704. The two auxiliary rods 705 are respectively arranged on the front and rear sides of the reciprocating lead screw 702, and the moving plate 703 is sleeved and slidably installed on the outer peripheries of the two auxiliary rods 705. Two first card slots 706 and two second card slots 707 are respectively formed on both sides of the moving plate 703. Two first push plates 708 and two second push plates 709 are respectively fixedly installed on both sides of the top of the first cleaning plate 501. The two first push plates 708 are used in cooperation with the two first card slots 706, and the two second push plates 709 are used in cooperation with the two second card slots 707.

[0057] The methods for automatic frost condensation processing include:

[0058] Start the servo motor 701. The servo motor 701 drives the reciprocating lead screw 702 to rotate, and the reciprocating lead screw 702 drives the moving plate 703 to move left and right reciprocally on the top of the box body 201:

[0059] When the moving plate 703 moves to the left, the first card slot 706 is sleeved on the first push plate 708, and the first push plate 708 is pushed to move the first cleaning plate 501 to the left. During the movement of the first cleaning plate 501, under the resistance limitation of the silicone rubber defrosting block 504 and the spiral heat exchange tube 2042, the first cleaning plate 501 squeezes the second spring 508 arranged on the left. When the second spring 508 reaches the compression limit, the first cleaning plate 501 pushes the first limiting plate 507 on the left to move through the second spring 508, and the first sliding rod 506 drives the first limiting plate 507 on the right to move to the left. At this time, the first limiting plate 507 on the right drives the first connecting plate 5010 to push the first limiting plate 507 on the right of the topmost third cleaning plate 503 to move to the left, and squeezes the second spring 508 arranged on the right of the third cleaning plate 503. When the second spring 508 reaches the compression limit, the third cleaning plate 503 is pushed to move to the left. At this time, the first cleaning plate 501 and the second cleaning plate 502 are distributed in a stepped shape. The third cleaning plate 503 squeezes the third spring 509 arranged on the left. When the third spring 509 reaches the compression limit, the third cleaning plate 503 pushes the second limiting plate 5012 on the left to move through the third spring 509, and the second sliding rod 5011 drives the second limiting plate 5012 on the right to move to the left. At this time, the second limiting plate 5012 on the right drives the second connecting plate 5013, and pushes the second limiting plate 5012 arranged on the right of the second topmost third cleaning plate 503 to move to the left. The second topmost is the third cleaning plate 503 whose height is only second to the topmost third cleaning plate 503. After the second limiting plate 5012 squeezes the third spring 509 and makes it reach the compression limit, the second topmost third cleaning plate 503 is pushed to move to the left. Similarly, as the first cleaning plate 501 continues to move to the left, several third cleaning plates 503 and the second cleaning plate 502 move in sequence, as shown in the appendix Figure 12 As shown, they are distributed in a stepped shape. When the first cleaning plate 501 moves to contact the mounting shell 2041 arranged on the left, the servo motor 701 is turned off. Under the elastic force of the second spring 508 and the third spring 509, several third cleaning plates 503 and the second cleaning plate 502 contact the mounting shell 2041 arranged on the left, and then the servo motor 701 is started;

[0060] When the moving plate 703 moves to the right, the second card slot 707 is sleeved on the second push plate 709 and pushes the second push plate 709 to move the first cleaning plate 501 to the right. During the movement of the first cleaning plate 501, under the resistance limitation of the silicone rubber defrosting block 504 and the spiral heat exchange tube 2042, the first cleaning plate 501 squeezes the second spring 508 arranged on the right side. When the second spring 508 reaches the compression limit, the first cleaning plate 501 pushes the first limiting plate 507 on the right side through the second spring 508, causing the first sliding rod 506 to drive the first limiting plate 507 on the left side to move to the right. At this time, the first limiting plate 507 on the left side drives the first connecting plate 5010 to move, and pushes the first limiting plate 507 on the left side of the topmost third cleaning plate 503 to move to the right, and squeezes the second spring 508 arranged on the left side of the third cleaning plate 503. When the second spring 508 reaches the compression limit, it pushes the third cleaning plate 503 to move to the right. At this time, the first cleaning plate 501 and the second cleaning plate 502 are arranged in a stepped manner. The third cleaning plate 503 squeezes the third spring 509 arranged on the right side. When the third spring 509 reaches the compression limit, the third cleaning plate 503 pushes the second limiting plate 5012 on the right side through the third spring 509, causing the second sliding rod 5011 to drive the second limiting plate 5012 on the left side to move to the right. At this time, the second limiting plate 5012 on the left side drives the second connecting plate 5013, and pushes the second limiting plate 5012 arranged on the left side of the second topmost third cleaning plate 503 to move to the right. After the second limiting plate 5012 squeezes the third spring 509 and makes it reach the compression limit, it pushes the second topmost third cleaning plate 503 to move to the right. Similarly, as the first cleaning plate 501 continues to move to the right, several third cleaning plates 503 and second cleaning plates 502 move in sequence and are arranged in a stepped manner. When the first cleaning plate 501 moves to contact the installation shell 2041 arranged on the right side, the servo motor 701 is turned off. Under the elastic force of the second spring 508 and the third spring 509, several third cleaning plates 503 and second cleaning plates 502 contact the installation shell 2041 arranged on the left side, and then the servo motor 701 is started;

[0061] During the movement of the first cleaning plate 501, the third cleaning plate 503 and the second cleaning plate 502, the silicone rubber defrosting block 504 is driven to scrape the frost on the spiral heat exchange tube 2042, and the fallen frost lands on the bottom of the inner cavity of the heat exchange cavity 202.

[0062] In this embodiment, the automatic cleaning of the frost on the surface of the spiral heat exchange tube 2042 is realized. At the same time, it can also ensure the effective separation of the fallen frost from the spiral heat exchange tube 2042 during the cleaning process.

[0064] As an improvement over the previous embodiment, in order to achieve the energy-saving treatment of frost accumulation, a high-efficiency spiral food quick-freezing machine is provided with a frost cleaning component 6 inside the heat exchange cavity 202. Specifically, the frost cleaning component 6 includes a scraper 601. On the front and rear sides of the top of the scraper 601, docking plates 606 are fixedly installed. The tops of the docking plates 606 penetrate through the extrusion cover 602 and are fixedly connected to the bottom of the moving plate 703. The top of the outer periphery of the scraper 601 is sleeved and slidably installed with the extrusion cover 602. Several vertical rods 603 are fixedly installed at the top of the inner cavity of the extrusion cover 602. Blind holes 604 adapted to the vertical rods 603 are formed at the top of the scraper 601. A fourth spring 605 is arranged between the bottom end of the vertical rod 603 and the bottom of the inner cavity of the blind hole 604. The bottom of the scraper 601 is in sliding contact with the bottom of the inner cavity of the heat exchange cavity 202, and the front and rear sides of the scraper 601 and the extrusion cover 602 are respectively in sliding contact with the front and rear sides of the inner cavity of the heat exchange cavity 202. Further, in order to ensure that the frost effectively enters the isolation cavity 203, first inclined surfaces 607 are arranged on both sides of the top of the extrusion cover 602. Second inclined surfaces 2043 are arranged at the bottom of the opposite sides of the two mounting shells 2041, and the second inclined surfaces 2043 are used in cooperation with the first inclined surfaces 607.

[0065] As a preferred solution, both sides of the bottom of the inner cavity of the heat exchange cavity 202 are communicated with the isolation cavity 203 through frost passing openings 205. Elastic sealing components 8 are fixedly installed on both sides of the inner cavity of the heat exchange cavity 202. Specifically, the elastic sealing component 8 includes a sealing strip 801. Several guide rods 802 are fixedly installed on one side of the sealing strip 801. One end of the guide rod 802 is fixedly installed with a first spring 803. A sleeve 804 is sleeved on the outer periphery of one end of the guide rod 802. The first spring 803 is arranged inside the sleeve 804. Several sleeves 804 are fixedly installed on one side of the inner cavity of the isolation cavity 203. The sealing strip 801 is used in cooperation with the frost passing opening 205. In this way, when the first spring 803 is not subjected to an extrusion force, it can push the sealing strip 801 to block the frost passing opening 205, thereby ensuring the effective separation of the heat exchange cavity 202 and the isolation cavity 203, which provides a good storage environment for the condensed frost.

[0066] As a detailed description, the cooperation mode of the frost cleaning component 6 and the elastic sealing component 8 includes:

[0067] The frost scraped from the spiral heat exchange tube 2042 falls onto the bottom of the inner cavity of the heat exchange chamber 202. During the leftward movement of the moving plate 703, the moving plate 703 drives the scraping plate 601 to move leftward, scraping the frost that has fallen onto the bottom of the inner cavity of the heat exchange chamber 202, causing the frost to move leftward. At the same time, the scraping plate 601 drives the extrusion cover 602 to move leftward, causing the extrusion cover 602 to contact and squeeze the left sealing strip 801, pushing the sealing strip 801 to push the guide rod 802 to squeeze the first spring 803. When the sealing strip 801 disengages from the frost passage 205, the vertical edge on the left side of the scraping plate 601 moves to the position of the frost passage 205, and part of the frost falls into the isolation chamber 203. As the extrusion cover 602 continues to move leftward, the extrusion cover 602 moves downward under the cooperation of the first inclined surface 607 on its left side and the second inclined surface 2043. During this process, the extrusion cover 602 squeezes the vertical rod 603 downward to squeeze the fourth spring 605. At the same time, the extrusion cover 602 pushes all the residual frost between the sealing strip 801 and the scraping plate 601 into the isolation chamber 203;

[0068] During the rightward movement of the moving plate 703, the moving plate 703 drives the scraping plate 601 to move the extrusion cover 602 rightward. Under the elastic force of the first spring 803, the sealing strip 801 remains in contact with the extrusion cover 602 until the sealing strip 801 completes the sealing of the frost passage 205, at which point the extrusion cover 602 separates from the sealing strip 801. And under the elastic force of the fourth spring 605, the extrusion cover 602 continuously moves upward until it is reset. The scraping plate 601 scrapes the frost that has fallen onto the bottom of the inner cavity of the heat exchange chamber 202, causing the frost to move rightward. When the scraping plate 601 drives the extrusion cover 602 to contact and squeeze the right sealing strip 801, it pushes the sealing strip 801 to push the guide rod 802 to squeeze the first spring 803. When the sealing strip 801 disengages from the frost passage 205, the vertical edge on the right side of the scraping plate 601 moves to the position of the frost passage 205, and part of the frost falls into the isolation chamber 203. As the extrusion cover 602 continues to move rightward, the extrusion cover 602 moves downward under the cooperation of the first inclined surface 607 on its right side and the second inclined surface 2043. During this process, the extrusion cover 602 squeezes the vertical rod 603 downward to squeeze the fourth spring 605. At the same time, the extrusion cover 602 pushes all the residual frost between the sealing strip 801 and the scraping plate 601 into the isolation chamber 203, as shown in the attached Figure 9 figure;

[0069] During the leftward movement of the moving plate 703, the moving plate 703 drives the scraping plate 601 to move the extrusion cover 602 leftward. Under the elastic force of the first spring 803, the sealing strip 801 remains in contact with the extrusion cover 602 until the sealing strip 801 completes the sealing of the frost passage 205, at which point the extrusion cover 602 separates from the sealing strip 801. And under the elastic force of the fourth spring 605, the extrusion cover 602 continuously moves upward until it is reset.

[0070] As a preferred solution, in order to achieve the melting treatment of the frost, storage boxes 9 are fixedly installed on both sides of the bottom of the box body 201. The top of the storage box 9 is communicated with the isolation cavity 203 through an opening, and the two storage boxes 9 are respectively arranged directly below the two frost passing openings 205. When the condensed frost falls into the isolation cavity 203, it directly falls into the storage box 9. An electric heating grid plate 901 is fixedly installed at the bottom of the inner cavity of the storage box 9. A water passing pipe 902 is communicated on the opposite side of the two storage boxes 9, and a drain pipe 903 is communicated with the back of the water passing pipe 902. The electric heating grid plate 901 is started regularly. After the condensed frost is melted into water, it is discharged through the water passing pipe 902 and the drain pipe 903. There is no need to keep the electric heating grid plate 901 on all the time, which has the advantage of energy saving.

[0071] The advantage of the second embodiment relative to the first embodiment is that the frost falling on the bottom of the inner cavity of the heat exchange cavity 202 is agglomerated and isolated, and the agglomerated frost is melted by regularly turning on the electric heating grid plate 901, reducing the power consumption.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
