Description

Technical Field

[0001] The invention relates to the technical field of quick freezing processing, in particular to a high-efficiency spiral food quick freezing machine. Background Art

[0002] The double-screw food quick freezer is a processing equipment that freezes the center temperature of quick-frozen food to below minus 18 degrees in a short period of time to reduce the loss of nutrients and retain its original flavor. However, during the operation of the double-screw quick freezer, frost is prone to occur in the condensation and heat exchange part, which affects the heat exchange efficiency and seriously affects the speed efficiency of food. The reason for frost is often that the surface temperature of the condenser heat exchange tube drops to a certain level, usually below zero degrees. At this time, the moisture in the air may condense into frost on the heat exchange tube.

[0003] As described in the application number 202410426547.1, the efficient and energy-saving double-spiral quick-freezing machine for large-scale food quick-freezing defrosts the thick frost condensed on the surface of the spiral heat exchange tube by means of automatic mechanical defrosting. The transmission component drives multiple groups of movable sweeping brushes to reciprocate and defrost the surface of the spiral heat exchange tube, directly acting on the frost layer on the surface of the heat exchange tube to separate it from the heat exchange tube, and the fallen condensed frost is stored in a water storage plate, and an electric heating plate is used for defrosting.

[0004] Based on the search of the above information, it can be seen that when multiple groups of movable sweeping brush plates are used to wipe and defrost the surface of the spiral heat exchange tube, the multiple layers of movable sweeping brush plates overlap in the vertical direction, and the wiped frost is easy to fall directly on the movable sweeping brush plates. Due to the close distance to the heat exchange tube, it is easy to aggravate the frost on the surface of the heat exchange tube, and after the wiped frost falls into the water storage plate, the electric heating plate is heated and defrosted. At this time, in order to avoid the interference of frost on the heat exchange tube, it is often necessary to keep the electric heating plate open, and the waste of electric energy is serious. For this reason, a high-efficiency spiral food quick freezer is specially proposed, which wipes the frost on the spiral heat exchange tube in turn to ensure that the wiped frost can effectively fall away from the spiral heat exchange tube, and further avoids the interference of frost on the spiral heat exchange tube by collecting, isolating and storing the fallen frost, and melts the accumulated fallen frost by regular heating, effectively reducing the power consumption.

The condensing assembly 2 is arranged between the two spiral conveying members 3 and arranged outside the evaporator 4 to cool and liquefy the refrigerant vapor. The feeding end of one spiral conveying member 3 sequentially passes through the evaporator 4 and the processing chamber 1 and extends to one side of the processing chamber 1 as a food loading station. The discharging end of the other spiral conveying member 3 sequentially passes through the evaporator 4 and the processing chamber 1 and extends to the other side of the processing chamber 1 as a quick-frozen food unloading station. The food to be processed is placed at the food loading station. The food to be processed is transported to the processing chamber 1 by the spiral conveying member 3 and enters the evaporator 4 for quick freezing. The quick-frozen food is then taken out through the quick-frozen food unloading station.

Both ends of the third spring 509 are respectively in contact with the second limit plate 5012 and the opposite side of the load-reducing groove 505. Two adjacent first limit plates 507 in the vertical direction are fixed by a first connecting plate 5010, and several first connecting plates 5010 are arranged at intervals. Two adjacent second limit plates 5012 in the vertical direction are fixed by a second connecting plate 5013, and several second connecting plates 5013 are arranged at intervals.

[0023] As a detailed description, the second spring 508 and the third spring 509 are used to transfer the traction force between the first cleaning plate 501, the second cleaning plate 502 and several third cleaning plates 503, and the friction between the silicone rubber defrosting block 504 and the spiral heat exchange tube 2042 can make the first cleaning plate 501, several third cleaning plates 503 and the second cleaning plate 502 have a stepped distribution during their movement to ensure that the fallen frost falls smoothly into the bottom of the inner cavity of the heat exchange chamber 202.

[0024] As a preferred solution, in order to realize the automatic processing of frost, a reciprocating drive assembly 7 is arranged on the top of the box body 201, and the reciprocating drive assembly 7 includes a servo motor 701. The output end of the servo motor 701 is fixedly connected to a reciprocating screw 702 through a coupling. The outer periphery of the reciprocating screw 702 is provided with a movable plate 703 used in conjunction with it. In order to ensure the stable movement of the movable plate 703, the servo motor 701 is fixedly installed on one side of the box body 201 through a fixed plate. Ear plates 704 are fixedly installed on the front and rear sides of both sides of the top of the box body 201. One of the opposite sides of the two ear plates 704 An auxiliary rod 705 is fixedly installed in the middle, and the two auxiliary rods 705 are respectively arranged on the front and rear sides of the reciprocating screw 702, and the movable plate 703 is sleeved and slidably installed on the outer periphery of the two auxiliary rods 705. Two first card grooves 706 and two second card grooves 707 are respectively provided on both sides of the movable 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 conjunction with the two first card grooves 706, and the two second push plates 709 are used in conjunction with the two second card grooves 707.

[0025] Ways to automate frost treatment include: The servo motor 701 is started, and the servo motor 701 drives the reciprocating screw 702 to rotate, and the reciprocating screw 702 drives the moving plate 703 to move back and forth on the top of the box body 201: When the movable plate 703 moves to the left, the first slot 706 is sleeved on the first push plate 708, and the first push plate 708 is pushed to make the first cleaning plate 501 move to the left. During the movement of the first cleaning plate 501, under the resistance limit of the silicone rubber defrosting block 504 and the spiral heat exchange tube 2042, the first cleaning plate 501 squeezes the second spring 508 set on the left side. When the second spring 508 reaches the compression limit, the first cleaning plate 501 pushes the first limiting plate 507 on the left side to move through the second spring 508, and makes the first sliding bar 506 drive the first limiting plate 507 on the right side to move to the left. At this time, the first limiting plate 507 on the right side drives the first connecting plate 5010 to push the first limiting plate 507 on the right side of the top third cleaning plate 503 to move to the left, and squeezes the second spring 508 set on the right 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 left. At this time, the first The plate 501 and the second cleaning plate 502 are distributed in a stepped manner, and the third cleaning plate 503 squeezes the third spring 509 set on the left side. When the third spring 509 reaches the compression limit, the third cleaning plate 503 pushes the second limiting plate 5012 on the left side to move through the third spring 509, so that the second sliding bar 5011 drives the second limiting plate 5012 on the right side to move leftward. At this time, the second limiting plate 5012 on the right side drives the second connecting plate 5013 and pushes the second limiting plate 5012 set on the right side of the second top cleaning plate 503 to move leftward, wherein the second top is the third cleaning plate 503 whose height is second only to the third cleaning plate 503 at the highest point. After the second limiting plate 5012 squeezes the third spring 509 and makes it reach the compression limit, it pushes the third cleaning plate 503 at the second top to move leftward. Similarly, as the first cleaning plate 501 continues to move to the left, several third cleaning plates 503 and second cleaning plates 502 move in sequence, as shown in the attached figure. Fig.12 As shown, they are distributed in a stepped manner. When the first cleaning plate 501 moves to contact the mounting shell 2041 set on the left, the servo motor 701 is turned off. Under the elastic force of the second spring 508 and the third spring 509, a plurality of third cleaning plates 503 and the second cleaning plates 502 contact the mounting shell 2041 set on the left, and then the servo motor 701 is started; When the movable plate 703 moves to the right, the second slot 707 is sleeved on the second push plate 709, and the second push plate 709 is pushed to make the first cleaning plate 501 move to the right. During the movement of the first cleaning plate 501, under the resistance limit of the silicone rubber defrosting block 504 and the spiral heat exchange tube 2042, the first cleaning plate 501 squeezes the second spring 508 set 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, so that the first sliding rod 506 drives the left The first limiting plate 507 on the left side moves 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 third cleaning plate 503 on the top to move to the right, and squeezes the second spring 508 set on the left side 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 right. At this time, the first cleaning plate 501 and the second cleaning plate 502 are distributed in a stepped shape, and the third cleaning plate 503 is pressed against the third spring 509 set on the right side. The third cleaning plate 503 is pressed and squeezed. When the third spring 509 reaches the compression limit, the third cleaning plate 503 pushes the second limiting plate 5012 on the right side to move through the third spring 509, so that the second sliding bar 5011 drives 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 set on the left side of the third cleaning plate 503 at the second top 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 limiting plate 5012 on the second top The third cleaning plate 503 at the top moves to the right. Similarly, as the first cleaning plate 501 continues to move to the right, a plurality of third cleaning plates 503 and second cleaning plates 502 move in sequence and are distributed in a stepped manner. When the first cleaning plate 501 moves to contact with the mounting shell 2041 set on the right, the servo motor 701 is turned off. Under the elastic force of the second spring 508 and the third spring 509, a plurality of third cleaning plates 503 and second cleaning plates 502 contact with the mounting shell 2041 set on the left, and then the servo motor 701 is started. 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 off the condensed frost on the spiral heat exchange tube 2042 , and the fallen frost falls to the bottom of the inner cavity of the heat exchange cavity 202 .

[0026] In this embodiment, the frost on the surface of the spiral heat exchange tube 2042 is automatically removed, and at the same time, the frost and the spiral heat exchange tube 2042 can be effectively separated during the removal process.

The top of the docking plate 606 passes through the extrusion cover 602 and is fixedly connected to the bottom of the movable plate 703. The top of the outer periphery of the scraper 601 is sleeved and slidably installed with the extrusion cover 602. The top of the inner cavity of the extrusion cover 602 is fixedly installed with a plurality of vertical rods 603. The top of the scraper 601 is provided with a connection with the vertical rods 603. The 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 chamber 202, and the front and rear sides of the scraper 601 and the extrusion cover 602 are in sliding contact with the front and rear sides of the inner cavity of the heat exchange chamber 202 respectively. It is further explained that in order to ensure that the fallen frost effectively enters the isolation chamber 203, the first inclined surfaces 607 are arranged on both sides of the top of the extrusion cover 602, and the bottoms of the opposite sides of the two mounting shells 2041 are provided with second inclined surfaces 2043, and the second inclined surfaces 2043 are used in conjunction with the first inclined surfaces 607.

[0028] As a preferred solution, both sides of the bottom of the inner cavity of the heat exchange chamber 202 are connected to the isolation chamber 203 through the frost port 205, and elastic sealing components 8 are fixedly installed on both sides of the inner cavity of the heat exchange chamber 202. Specifically, the elastic sealing component 8 includes a sealing strip 801, and a plurality of guide rods 802 are fixedly installed on one side of the sealing strip 801, and a first spring 803 is fixedly installed on one end of the guide rod 802. A sleeve 804 is sleeved on the outer periphery of one end of the guide rod 802, and the first spring 803 is arranged inside the sleeve 804. A plurality of sleeves 804 are fixedly installed on one side of the inner cavity of the isolation chamber 203. The sealing strip 801 is used in conjunction with the frost port 205. In this way, when the first spring 803 is not subjected to the extrusion force, the sealing strip 801 can be pushed to seal the frost port 205, thereby ensuring the effective separation of the heat exchange chamber 202 and the isolation chamber 203, which provides a good storage environment for frost.

[0029] As a detailed description, the frost cleaning component 6 and the elastic blocking component 8 are used in combination as follows: The frost scraped off from the spiral heat exchange tube 2042 falls on the bottom of the inner cavity of the heat exchange chamber 202. When the movable plate 703 moves to the left, the movable plate 703 drives the scraper 601 to move to the left, scraping the frost falling on the bottom of the inner cavity of the heat exchange chamber 202, so that the frost moves to the left. At the same time, the scraper 601 drives the extrusion cover 602 to move to the left, so that the extrusion cover 602 contacts and squeezes the blocking strip 801 on the left, pushing the blocking strip 801 to push the guide rod 802 to squeeze the first spring 803. When the blocking strip 801 is separated from the first spring 803, the first spring 803 is pressed against the second spring 803. When passing through the frost opening 205, the left vertical edge of the scraper 601 moves to the frost opening 205, and part of the condensed frost falls into the isolation chamber 203. As the extrusion cover 602 continues to move to the left, 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 the process, the extrusion cover 602 presses the vertical rod 603 downward to squeeze the fourth spring 605. At the same time, the extrusion cover 602 pushes all the residual condensed frost between the sealing strip 801 and the scraper 601 into the isolation chamber 203. When the movable plate 703 moves to the right, the movable plate 703 drives the scraper 601 to move the extrusion cover 602 to the right. Under the elastic force of the first spring 803, the blocking strip 801 and the extrusion cover 602 remain in contact with each other until the blocking strip 801 completes the blocking of the frost opening 205. The extrusion cover 602 is separated from the blocking strip 801. Under the elastic force of the fourth spring 605, the extrusion cover 602 continues to move upward until it is reset, scraping the frost that falls on the bottom of the inner cavity of the heat exchange chamber 202, so that the frost moves to the right. When the scraper 601 drives the extrusion cover 602 to contact and squeeze the sealing strip 801 on the right side, the sealing strip 801 is pushed. 801 pushes the guide rod 802 to squeeze the first spring 803. When the blocking strip 801 is separated from the frost opening 205, the vertical edge of the right side of the scraper 601 moves to the frost opening 205, and part of the frost falls into the isolation chamber 203. As the squeezing cover 602 continues to move to the right, the squeezing cover 602 moves downward with the cooperation of the first inclined surface 607 and the second inclined surface 2043 on its right side. During the process, the squeezing cover 602 squeezes the vertical rod 603 downward to squeeze the fourth spring 605. At the same time, the squeezing cover 602 pushes all the residual frost between the blocking strip 801 and the scraper 601 into the isolation chamber 203, as shown in the attached figure. Fig. 9 As shown; During the movement of the movable plate 703 to the left, the movable plate 703 drives the scraper 601 to move the extrusion cover 602 to the left. Under the elastic force of the first spring 803, the sealing strip 801 and the extrusion cover 602 maintain contact until the sealing strip 801 completes the sealing of the frost opening 205. The extrusion cover 602 is separated from the sealing strip 801, and under the elastic force of the fourth spring 605, the extrusion cover 602 continues to move upward until it is reset.

[0030] As a preferred solution, in order to melt 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 connected to the isolation chamber 203 through an opening, and the two storage boxes 9 are respectively arranged directly below the two frost ports 205. When the frost falls into the isolation chamber 203, it falls directly into the storage box 9. An electric heating grid plate 901 is fixedly installed on the bottom of the inner cavity of the storage box 9. The opposite sides of the two storage boxes 9 are connected to a water pipe 902, and the back of the water pipe 902 is connected to a drain pipe 903. The electric heating grid plate 901 is started regularly, and the frost is melted into water and discharged through the water pipe 902 and the drain pipe 903. There is no need to keep the electric heating grid plate 901 turned on, which has the advantage of energy saving.

[0031] The advantage of the second embodiment over the first embodiment is that the frost at the bottom of the inner cavity of the heat exchange cavity 202 is collected and isolated, and the collected frost is melted by periodically opening the electric heating grid plate 901, thereby reducing power consumption.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
