Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a double-spiral spraying device with an automatic spray valve structure for food processing. Background Technology

[0002] When producing and processing pre-cooked food, the pre-cooked food needs to be heated to a certain temperature for sterilization and cooking. Then, the cooked pre-cooked food is packaged and stored. During the production process, the temperature of the pre-cooked food after packaging is around 80 degrees Celsius. In order to avoid the pre-cooked food being overcooked inside and affecting its taste, the pre-cooked food is usually placed on a conveyor belt for transportation, and the pre-cooked food is cooled down by spraying low-temperature cold water during transportation.

[0003] In practical applications, because the lower surface of the pre-cooked food is in constant contact with the conveyor belt during the transfer process, the sprayed cold water has difficulty contacting the lower surface of the pre-cooked food, thus affecting the cooling speed of the pre-cooked food by the cold water, resulting in poor cooling effect and low working efficiency of the equipment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in cooling the lower surface of pre-prepared food, resulting in poor cooling effect and low working efficiency. The invention proposes a double-spiral spraying device with an automatic spray valve structure for food processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-helix spraying device for food processing with an automatic spray valve structure, comprising a water storage tank and a spraying method. Two frames are fixedly connected to the bottom of the inner wall of the water storage tank. Several support pipes are welded to the surface of the frames, and the support pipes are connected to the frames. Double-helix guide rails are welded to the outer walls of the support pipes. A chain belt is driven through the surface of the double-helix guide rails. A bracket is fixedly connected to the surface of the frames, and the bracket is driven through the chain belt. A reducer is fixedly connected to the upper surface of the frames, and the side wall of the reducer... The system is connected to a motor, and the output end of the reducer is fixedly connected to a rotating cage. The rotating cage is connected to a chain belt drive. A cabinet is fixedly connected to the upper part of the outer wall of the water storage tank. Two water pumps are fixedly connected to the inner wall of the cabinet. The outlet end of the water pump is connected to a water supply pipe, which is connected to a frame. The inlet end of the water pump is connected to an inlet pipe, and the end of the inlet pipe away from the water pump is connected to the water storage tank. An annular pipe is connected to the top of the frame. Several first nozzles are connected to the arc surface of the annular pipe. The first nozzles are located above the double helical guide rail. Second nozzles are connected to the side wall of the support pipe.

[0006] The effect achieved by the above components is that, through the cooperation between the components, both sides of the pre-cooked food can be cooled down simultaneously, and cold water can be directly in contact with the pre-cooked food, which greatly improves the cooling speed of the pre-cooked food, improves the cooling effect of the equipment, and increases the working efficiency of the equipment.

[0007] Preferably, a V-shaped groove is provided at the outlet of the second nozzle, the angle of the V-shaped groove on the second nozzle is in the range of 36-77 degrees, and the outlet of the second nozzle is inclined upward.

[0008] The effect achieved by the above components is that by changing the opening angle of the V-groove on the second nozzle, the spraying range of the second nozzle can be adjusted, so that cold water can be sprayed onto the pre-cooked food more accurately.

[0009] Preferably, the inner wall of the second nozzle is made of stainless steel, and the inner wall of the V-groove on the second nozzle is polished.

[0010] The effects achieved by the above components are as follows: Since the inner wall of the second nozzle is made of stainless steel, the outlet of the second nozzle will not rust or become clogged, thereby extending the service life of the second nozzle; Since the inner wall of the V-groove is polished, the inner wall of the V-groove is smooth, allowing water to flow through quickly.

[0011] Preferably, the surface of the chain belt has several through holes, and the running speed of the outer edge of the chain belt is in the range of 10-25m / min.

[0012] The effect achieved by the above components is that by adjusting the running speed of the chain belt, the pre-cooked food can be fully contacted with cold water, thereby cooling pre-cooked food of different volumes or weights and expanding the applicability of the equipment.

[0013] Preferably, the upper surface of the bracket is provided with a positioning structure, the positioning structure including a mounting plate, the mounting plate being fixedly connected to the bracket, an electric telescopic rod being fixedly connected inside the mounting plate, a pressure plate being fixedly connected to the output end of the electric telescopic rod, and a pressure plate being fixedly connected to the side of the pressure plate away from the electric telescopic rod. The vertical cross-section of the mounting plate is U-shaped, and a fixing rod is fixedly connected to the side of the two arms of the mounting plate that are close to each other. Two circular tubes are slidably sleeved on the arc surface of the fixing rod, and a connecting plate is fixedly connected to the arc surface of the circular tubes. Both sides of the connecting plate are rotated. The mounting plate is rotatably connected to a roller, the arc surface of which is slidably connected to a transmission plate. Positioning boxes are rotatably connected to the sides of the mounting plate where they are close to each other. A clamping plate is fixedly connected to the upper surface of the positioning box. A sliding plate is slidably connected to the inner wall of the clamping plate. A sliding rod is fixedly connected to the upper surface of the sliding plate. The end of the sliding rod away from the sliding plate is fixedly connected to a sliding tube. Two circular plates are fixedly connected to the arc surface of the fixing rod, both circular plates being located between two circular tubes. Two springs are sleeved on the arc surface of the fixing rod, with both ends of the springs fixedly connected to the circular plates and the circular tubes, respectively.

[0014] The effect achieved by the above components is that, by setting up a positioning structure, the distance between the two positioning boxes can be adjusted according to the size of the pre-cooked food, so that the pre-cooked food can be positioned at a designated position on the chain conveyor belt, which facilitates the subsequent cooling and temperature reduction of the pre-cooked food.

[0015] Preferably, the vertical cross-section of the transmission plate is "L" shaped, the angle between the long arm and the short arm of the transmission plate is an obtuse angle, and the short arm of the transmission plate is perpendicular to the horizontal plane.

[0016] The effect achieved by the above components is as follows: Since the angle between the long arm and the short arm of the transmission plate is an obtuse angle, and the short arm of the transmission plate is perpendicular to the horizontal plane, the long arm of the transmission plate is inclined to the horizontal plane. Therefore, when the long arm of the transmission plate slides, it can squeeze the roller, so that the roller can move in the horizontal direction.

[0017] Preferably, two U-shaped plates are fixedly connected to the bottom of the upper end of the mounting plate, and the inner wall of the U-shaped plates is slidably connected to the pressure plate.

[0018] The effect achieved by the above components is that the movement of the output end of the electric telescopic rod will cause the pressure plate to slide along the inner wall of the U-shaped plate, and the U-shaped plate will restrict the sliding path of the pressure plate.

[0019] Preferably, the inner wall of the positioning box is provided with an auxiliary structure, the auxiliary structure including an adjusting plate, the adjusting plate being slidably connected to the inner wall of the positioning box, the surface of the adjusting plate having a clearance hole, a screw threaded into the side wall of the positioning box, a push plate being rotatably connected to the end of the screw near the adjusting plate, a circular groove being provided in the positioning box relative to the push plate, the size of the circular groove in the positioning box being adapted to the size of the push plate, an anti-slip component being provided on the side of the push plate away from the screw, the anti-slip component including a frustum pad, the frustum pad being made of rubber, the frustum pad being fixedly connected to the push plate, a cavity being provided on the surface of the frustum pad, and eight elastic sheets being made of elastic steel being fixedly connected to the inner wall of the frustum pad, the elastic sheets being fixedly connected to the push plate.

[0020] The effect achieved by the above-mentioned components is that by setting up auxiliary structures, it is possible for staff to make fine adjustments to the distance between the two positioning boxes, which can better adjust the position of the pre-prepared dishes, thereby further facilitating the use by staff.

[0021] Preferably, the side wall of the positioning box is provided with a ranging component, the ranging component includes two strip holes, the strip holes are opened in the side wall of the positioning box, the inner wall of the strip holes on the positioning box is slidably connected with a protrusion, the protrusion is fixedly connected to an adjusting plate, a ranging rod is fixedly connected to the side of the two protrusions that are close to each other, an indicator plate is fixedly connected to the arc surface of the ranging rod, and a scale plate is fixedly connected to the side of the positioning box that is close to the indicator plate, the scale plate and the indicator plate are slidably connected.

[0022] The effect achieved by the above components is as follows: the sliding of the adjustment plate will cause the protrusion to slide along the inner wall of the strip hole, the sliding of the protrusion will cause the distance measuring rod to slide, the sliding of the distance measuring rod will cause the indicator plate to slide along the surface of the scale plate. At this time, the scale plate can facilitate the staff to observe the sliding distance of the adjustment plate, and the indicator plate can facilitate the staff to observe.

[0023] Preferably, the spraying method specifically includes the following:

[0024] S1. First, adjust the position of the positioning box and the adjustment plate according to the size of the packaged pre-cooked food, so that the distance between the two adjustment plates matches the size of the pre-cooked food.

[0025] S2. The pre-prepared food is spiraled upward by a chain conveyor belt. During this process, the positioning box and the adjusting plate can position the pre-prepared food at a designated position on the chain conveyor belt.

[0026] S3. Start the water pump to make the second nozzle start draining water. Since the outlet of the second nozzle is tilted upward and the surface of the chain belt has through holes, the water discharged from the second nozzle will come into contact with the lower surface of the pre-cooked food through the through holes. At this time, the water will cool the pre-cooked food once. Then, the water will drip down due to its own gravity. The dripping water will flow to the upper surface of the pre-cooked food below, thereby cooling the upper surface of the pre-cooked food a second time.

[0027] S4. When the pre-cooked food moves to the top along the chain conveyor, the water flow discharged from the first nozzle will cool the pre-cooked food again. The first nozzle can spray a solid cone-shaped water flow. Multiple first nozzles can work together to form a water curtain around the double helix guide rail. The water curtain can reduce the influence of the external ambient temperature on the temperature of the pre-cooked food.

[0028] S5. As the chain belt continues to operate, the pre-cooked food will move to another chain belt. At this time, the pre-cooked food will follow the other chain belt and move spirally from top to bottom. During this process, the first nozzle and the second nozzle will continuously cool the pre-cooked food.

[0029] S6. Store the cooled pre-cooked food.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0031] 1. In this invention, when it is necessary to store the pre-prepared food after packaging, the motor is started. The output end of the motor rotates, which drives the reducer to rotate. At this time, the output end of the reducer rotates the electric rotating cage. The rotation of the rotating cage drives the chain belt to move along the surface of the double helical guide rail. Then, the heated pre-prepared food is placed on the chain belt. At this time, the chain belt drives the pre-prepared food spiral to move from bottom to top. During this process, the water pump is started. The water pump inlet end draws cold water from the water storage tank through the water inlet pipe. The temperature of the cold water is 4-7℃. Then, the cold water flows through the water pump and flows along the inner wall of the water delivery pipe. The cold water flows into the frame, and then flows into the annular pipe and the support pipe. Then, the first nozzle and the second nozzle discharge the cold water. Due to the second nozzle... The outlet of the second nozzle is tilted upwards, so the water flow from the second nozzle will contact the lower surface of the pre-cooked food through the through-hole. At this time, the water flow will cool the pre-cooked food once. Then, due to its own gravity, the water will drip down, and the dripping water will flow to the upper surface of the pre-cooked food below, thus cooling the upper surface of the pre-cooked food a second time. Therefore, multiple second nozzles working together can simultaneously cool the upper and lower surfaces of the pre-cooked food, greatly improving the cooling speed and ensuring uniform cooling, thus improving the cooling effect of the equipment. By changing the opening angle of the V-groove on the second nozzle, the spray range of the second nozzle can be adjusted, allowing the cold water to be sprayed more accurately onto the pre-cooked food. The inner wall of the nozzle is made of stainless steel, so the outlet of the second nozzle will not rust or become clogged, thus extending its service life. Because the inner wall of the V-shaped groove is polished, it is smooth, allowing water to flow quickly. By adjusting the speed of the chain belt, the pre-cooked food can be fully in contact with cold water, thus cooling pre-cooked food of different volumes or weights, expanding the equipment's applicability. When the pre-cooked food moves to the top with the chain belt, the water flow from the first nozzle will further cool it. The first nozzle sprays a solid cone-shaped stream of water; multiple first nozzles working together form a water curtain surrounding the double-helix guide rail. This water curtain reduces the impact of ambient temperature on the pre-cooked food. The temperature effect further increases the cooling speed of the pre-cooked food. The pre-cooked food then moves to another conveyor belt, which drives the pre-cooked food spiral downwards. During this process, the first and second nozzles continuously cool the pre-cooked food. The first and second nozzles allow cold water to directly contact the surface of the pre-cooked food, thereby improving the heat exchange efficiency between the cold water and the pre-cooked food, further enhancing the cooling effect. Through the cooperation of various components, the pre-cooked food can be cooled simultaneously on both sides, and cold water can directly contact the pre-cooked food, greatly increasing the cooling speed, improving the cooling effect of the equipment, and increasing the equipment's working efficiency.

[0032] 2. In this invention, by setting a positioning structure, before the pre-cooked food needs to be cooled, the electric telescopic rod is activated. The output end of the electric telescopic rod begins to extend, and the movement of the output end of the electric telescopic rod will cause the pressure plate to slide along the inner wall of the U-shaped plate. The U-shaped plate will restrict the sliding path of the pressure plate. The sliding of the pressure plate will cause the transmission plate to slide. At this time, the long arm of the transmission plate will squeeze the roller. The movement of the roller will cause the two connecting plates to move closer to each other. The movement of the connecting plates will cause the round tube to slide along the arc surface of the fixed rod. At this time, the fixed rod will restrict the sliding path of the round tube. The sliding of the round tube will squeeze the spring. At this time, the spring is in a compressed state. The sliding rod, with the help of the round tube, will cause the sliding plate to slide along the inner wall of the clamping plate. The sliding plate will cause the clamping plate to rotate the positioning box, thereby adjusting the distance between the two positioning boxes. When the pre-cooked food moves with the chain plate, the pre-cooked food will contact the side wall of the positioning box. At this time, the positioning box will guide the sliding path of the pre-cooked food, causing the pre-cooked food to slide onto the chain plate. The positioning structure is positioned at a designated location on the conveyor belt to facilitate subsequent cooling of the pre-prepared food. When the positioning structure is not in use, the electric telescopic rod is activated again. At this time, the output end of the electric telescopic rod begins to retract and drives the pressure plate upward. The movement of the pressure plate causes the long arm of the transmission plate to disengage from the roller. At this time, the spring begins to extend, and the round tube slides away from the round plate with the help of the spring tension. The sliding of the connecting plate with the round tube causes the roller to re-engage with the long arm of the transmission plate. When the transmission plate moves to a certain position, the short arm of the transmission plate will engage with the roller. At this time, the short arm of the transmission plate prevents the roller from moving further and disengages from the long arm of the transmission plate. The sliding of the round tube will drive the sliding rod to slide, ultimately causing the two positioning boxes to rotate away from each other, thereby increasing the distance between the two positioning boxes. By setting up the positioning structure, the distance between the two positioning boxes can be adjusted according to the size of the pre-prepared food, so that the pre-prepared food can be positioned at a designated location on the conveyor belt, facilitating subsequent cooling of the pre-prepared food.

[0033] 3. In this invention, by setting an auxiliary structure, when the auxiliary structure is needed, first rotate the screw. The screw will move away from the adjusting plate via the thread. The movement of the adjusting plate will cause the push plate to slide into the inner wall of the circular groove. The circular groove serves to house the push plate. The movement of the push plate will cause the frustum pad to no longer adhere to the surface of the adjusting plate. At this time, the elastic sheet will return to its original shape due to its own elastic force. The movement of the elastic sheet will cause the frustum pad to move, thereby restoring the frustum pad to its original shape and minimizing edge curling, making it convenient for the next use. Then, the adjusting plate is pulled along the inner wall of the positioning box via the clearance hole. The sliding of the adjusting plate will cause the protrusion to slide along the inner wall of the strip hole. The sliding of the protrusion will cause the distance measuring rod to slide. The sliding of the distance measuring rod will cause the indicator plate to slide along the surface of the scale plate. At this time, the scale plate serves to facilitate the operator's observation of the sliding distance of the adjusting plate. The adjustment plate facilitates observation by staff. When the adjustment plate slides to the appropriate position, rotating the screw in the opposite direction causes the screw to drive the push plate closer to the adjustment plate via its thread. The push plate's movement causes the frustum pad to slide. Since the frustum pad is made of rubber, it deforms and expands outwards upon contact with the adjustment plate, expelling air from the cavity. At this point, the frustum pad adheres to the surface of the adjustment plate, thus restricting its position and preventing slippage. The adjustment plate further reduces the distance between the two positioning boxes, allowing them to position pre-prepared dishes of different sizes. By incorporating this auxiliary structure, staff can easily fine-tune the distance between the two positioning boxes, enabling better adjustment of the pre-prepared dish's position and further facilitating its use.

Detailed Implementation

[0048] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0049] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0050] Example 1, such as Figure 1-6 As shown, the present invention provides a double spiral spraying device with an automatic spray valve structure for food processing, including a water storage tank 1 and a spraying method.

[0051] like Figure 1-6As shown, two frames 2 are fixedly connected to the bottom of the inner wall of the water storage tank 1. Several support pipes 3 are welded to the surface of the frames 2, and the support pipes 3 are connected to the frames 2. Double helical guide rails 4 are welded to the outer walls of the support pipes 3. Chain belts 5 are driven to the surface of the double helical guide rails 4. A bracket 6 is fixedly connected to the surface of the frames 2, and the bracket 6 is driven to the chain belt 5. A reducer 9 is fixedly connected to the upper surface of the frames 2. A motor 10 is driven to the side wall of the reducer 9. A rotating cage 11 is fixedly connected to the output end of the reducer 9, and the rotating cage 11 is driven to the chain belt 5. The upper part of the outer wall of the water storage tank 1 is fixedly connected to the cabinet 12. The inner wall of the cabinet 12 is fixedly connected to two water pumps 13. The water outlet of the water pump 13 is connected to the water supply pipe 14, which is connected to the frame 2. The water inlet of the water pump 13 is connected to the water inlet pipe 15. The end of the water inlet pipe 15 away from the water pump 13 is connected to the water storage tank 1. The top of the frame 2 is connected to the annular pipe 16. The arc surface of the annular pipe 16 is connected to several first nozzles 17. The first nozzles 17 are located above the double helical guide rail 4. The side wall of the support pipe 3 is connected to the second nozzles 18.

[0052] like Figure 1-6 As shown, a V-shaped groove 19 is provided at the outlet of the second nozzle 18. The angle range of the V-shaped groove 19 on the second nozzle 18 is 36-77 degrees. The outlet of the second nozzle 18 is tilted upwards. By changing the opening angle of the V-shaped groove 19 on the second nozzle 18, the spray range of the second nozzle 18 can be adjusted, so that cold water can be sprayed more accurately onto the pre-cooked food. The inner wall of the second nozzle 18 is made of stainless steel, and the inner wall of the V-shaped groove 19 on the second nozzle 18 is polished. Because the inner wall of the second nozzle 18 is made of stainless steel, the outlet of the second nozzle 18 will not rust and become clogged, thus extending the service life of the second nozzle 18. Because the inner wall of the V-shaped groove 19 is polished, the inner wall of the V-shaped groove 19 is smooth, allowing water to flow through quickly. The surface of the chain belt 5 has several through holes. The running speed of the outer edge of the chain belt 5 is in the range of 10-25m / min. By adjusting the running speed of the chain belt 5, the pre-cooked food can be fully contacted with cold water, thereby cooling pre-cooked food of different volumes or weights and expanding the applicability of the equipment.

[0053] like Figure 7 and Figure 8 as well as Figure 9As shown, the positioning structure 7 includes a mounting plate 701, which is fixedly connected to the bracket 6. An electric telescopic rod 702 is fixedly connected inside the mounting plate 701. A pressure plate 703 is fixedly connected to the output end of the electric telescopic rod 702. A pressure plate 703 is fixedly connected to the side of the pressure plate 703 away from the electric telescopic rod 702. The vertical cross-section of the mounting plate 701 is U-shaped. A fixing rod 705 is fixedly connected to the side of the two arms of the mounting plate 701 that are close to each other. Two round tubes 706 are slidably sleeved on the arc surface of the fixing rod 705. A connecting plate 709 is fixedly connected to the arc surface of the round tubes 706. Rollers 712 are rotatably connected to both sides of the connecting plate 709. The arc surface of the mounting plate 701 is slidably connected to the transmission plate 704. The two arms of the mounting plate 701 are rotatably connected to the positioning box 707 on the side that is close to each other. The upper surface of the positioning box 707 is fixedly connected to the clamping plate 708. The inner wall of the clamping plate 708 is slidably connected to the sliding plate 715. The upper surface of the sliding plate 715 is fixedly connected to the sliding rod 714. The end of the sliding rod 714 away from the sliding plate 715 is fixedly connected to the sliding tube. The arc surface of the fixing rod 705 is fixedly connected to two circular plates 710. The two circular plates 710 are located between two circular tubes 706. The arc surface of the fixing rod 705 is fitted with two springs 711. The two ends of the springs 711 are fixedly connected to the circular plates 710 and the circular tubes 706 respectively.

[0054] like Figure 7 and Figure 8 as well as Figure 9 As shown, the vertical cross-section of the transmission plate 704 is L-shaped, and the angle between the long arm and the short arm of the transmission plate 704 is an obtuse angle. The short arm of the transmission plate 704 is perpendicular to the horizontal plane. Because the angle between the long arm and the short arm of the transmission plate 704 is obtuse and the short arm of the transmission plate 704 is perpendicular to the horizontal plane, the long arm of the transmission plate 704 is inclined to the horizontal plane. Therefore, when the long arm of the transmission plate 704 slides, it can squeeze the roller 712, allowing the roller 712 to move in the horizontal direction. Two U-shaped plates 713 are fixedly connected to the bottom of the upper end of the mounting plate 701. The inner wall of the U-shaped plate 713 is slidably connected to the pressure plate 703. When the output end of the electric telescopic rod 702 moves, it will drive the pressure plate 703 to slide along the inner wall of the U-shaped plate 713. The U-shaped plate 713 achieves the function of restricting the sliding path of the pressure plate 703.

[0055] like Figure 9-13As shown, the auxiliary structure 8 includes an adjusting plate 81, which is slidably connected to the inner wall of the positioning box 707. The surface of the adjusting plate 81 is provided with a clearance hole 87. A screw 82 is threaded into the side wall of the positioning box 707. A push plate 83 is rotatably connected to the end of the screw 82 near the adjusting plate 81. A circular groove 84 is provided in the positioning box 707 relative to the position of the push plate 83. The size of the circular groove 84 on the positioning box 707 is adapted to the size of the push plate 83. An anti-slip component 85 is provided on the side of the push plate 83 away from the screw 82. The anti-slip component 85 includes a frustum pad 851, which is made of rubber. The frustum pad 851 is fixedly connected to the push plate 83. A cavity is provided on the surface of the frustum pad 851. Eight elastic sheets 852, which are made of elastic steel, are fixedly connected to the inner wall of the frustum pad 851. The elastic sheets 852 are fixedly connected to the push plate 83. The positioning box 707 has a ranging component 86 on its side wall. The ranging component 86 includes two strip holes 861, which are formed in the side wall of the positioning box 707. A protrusion 862 is slidably connected to the inner wall of the strip hole 861 on the positioning box 707. The protrusion 862 is fixedly connected to the adjusting plate 81. A ranging rod 863 is fixedly connected to the side of the two protrusions 862 that is close to each other. An indicator plate 864 is fixedly connected to the arc surface of the ranging rod 863. The positioning box 707 is close to the indicator plate 864. A scale plate 865 is fixedly connected to one side. The scale plate 865 is slidably connected to the indicator plate 864. When the adjustment plate 81 slides, it will cause the protrusion 862 to slide along the inner wall of the strip hole 861. When the protrusion 862 slides, it will cause the distance measuring rod 863 to slide. When the distance measuring rod 863 slides, it will cause the indicator plate 864 to slide along the surface of the scale plate 865. At this time, the scale plate 865 and the indicator plate 864 can be used to facilitate the staff to observe the sliding distance of the adjustment plate 81.

[0056] like Figure 1-13As shown, the spraying method specifically includes the following: First, adjust the positions of the positioning box 707 and the adjusting plate 81 according to the size of the packaged pre-prepared food, so that the distance between the two adjusting plates 81 is adapted to the size of the pre-prepared food. Then, a chain belt 5 is used to spirally transport the pre-prepared food upwards. During this process, the positioning box 707 and the adjusting plate 81 ensure that the pre-prepared food is positioned at a designated location on the chain belt 5. The water pump 13 is then activated, causing the second nozzle 18 to begin draining water. Since the outlet of the second nozzle 18 is tilted upwards and the surface of the chain belt 5 has through holes, the water discharged from the second nozzle 18 will contact the lower surface of the pre-prepared food through the through holes. At this time, the water will cool the pre-prepared food once. Afterwards, the water will drip due to its own gravity. The water flows to the upper surface of the pre-cooked food below, thus providing secondary cooling to the upper surface of the pre-cooked food. When the pre-cooked food moves to the top with the chain belt 5, the water discharged from the first nozzle 17 will cool the pre-cooked food again. The first nozzle 17 can spray a solid cone-shaped water stream. Multiple first nozzles 17 work together to form a water curtain around the double spiral guide rail 4. The water curtain can reduce the influence of the external ambient temperature on the temperature of the pre-cooked food. The chain belt 5 continues to operate, causing the pre-cooked food to move to another chain belt 5. At this time, the pre-cooked food will follow the other chain belt 5 and spiral down. During this process, the first nozzle 17 and the second nozzle 18 will continuously cool the pre-cooked food and collect the cooled pre-cooked food.

[0057] Its overall working principle is as follows: Before cooling the pre-cooked food, the electric telescopic rod 702 is activated. The output end of the electric telescopic rod 702 begins to extend. The movement of the output end of the electric telescopic rod 702 will cause the pressure plate 703 to slide along the inner wall of the U-shaped plate 713. The U-shaped plate 713 will restrict the sliding path of the pressure plate 703. The sliding of the pressure plate 703 will cause the transmission plate 704 to slide. At this time, the long arm of the transmission plate 704 will squeeze the roller 712. The movement of the roller 712 will cause the two connecting plates 709 to move closer to each other. The movement of 09 will cause the round tube 706 to slide along the arc surface of the fixed rod 705. At this time, the fixed rod 705 will limit the sliding path of the round tube 706. The sliding of the round tube 706 will compress the spring 711. At this time, the spring 711 is in a compressed state. The sliding rod 714, with the help of the sliding of the round tube 706, will cause the sliding plate 715 to slide along the inner wall of the clamping plate 708. The sliding of the sliding plate 715 will cause the clamping plate 708 to rotate the positioning box 707, thereby adjusting the distance between the two positioning boxes 707. When the pre-cooked food moves with the chain belt 5, the pre-cooked food will... When the positioning box 707 contacts the side wall, it guides the pre-prepared food along its sliding path, allowing it to slide to the designated position on the chain belt 5 for subsequent cooling. When the positioning structure 7 is not in use, the electric telescopic rod 702 is activated again. The output end of the electric telescopic rod 702 retracts, causing the pressure plate 703 to move upwards. The movement of the pressure plate 703 disengages the long arm of the transmission plate 704 from the roller 712. At this point, the spring 711 extends, and the round tube 706 extends further with the help of the tension of the spring 711. As the circular plate 710 slides away from the circular plate, the connecting plate 709 slides with the help of the circular tube 706, causing the roller 712 to contact the long arm of the transmission plate 704 again. When the transmission plate 704 moves to a certain position, the short arm of the transmission plate 704 will contact the roller 712. At this time, the short arm of the transmission plate 704 will prevent the roller 712 from moving further and disengage from the long arm of the transmission plate 704. The sliding of the circular tube 706 will drive the slide rod 714 to slide, eventually causing the two positioning boxes 707 to rotate in a direction away from each other, thereby increasing the distance between the two positioning boxes 707.

[0058] When auxiliary structure 8 is needed, first rotate screw 82. Screw 82 will move away from adjusting plate 81 via the thread. The movement of adjusting plate 81 will cause push plate 83 to slide into the inner wall of circular groove 84. Circular groove 84 will then accommodate push plate 83. The movement of push plate 83 will cause frustum pad 851 to no longer adhere to the surface of adjusting plate 81. At this time, elastic sheet 852 will return to its original shape due to its own elasticity. The movement of elastic sheet 852 will cause frustum pad 851 to move, thus restoring frustum pad 851 to its original shape and preventing edge curling of frustum pad 851 as much as possible, making it convenient for the next use of frustum pad 851. Then, pull adjusting plate 81 along the inner wall of positioning box 707 via clearance hole 87. The sliding of adjusting plate 81 will cause protrusion 862 to slide along the inner wall of strip hole 861. The sliding of protrusion 862 will cause distance measuring rod 863 to slide. The sliding of distance measuring rod 863 will cause indicator plate 864 to slide along the scale. The surface of plate 865 slides, at which point plate 865 facilitates the observation of the sliding distance of adjustment plate 81 by the staff. Indicator plate 864 also facilitates the observation by the staff. When adjustment plate 81 slides to the appropriate position, screw 82 is rotated in the opposite direction. Screw 82 will drive push plate 83 to move closer to adjustment plate 81 through the thread. The movement of push plate 83 drives frustum pad 851 to slide. Since frustum pad 851 is made of rubber, it will deform and unfold in all directions after contacting adjustment plate 81, and the air in the cavity will be expelled. At this time, frustum pad 851 will be attracted to the surface of adjustment plate 81, thereby restricting the position of adjustment plate 81 and preventing adjustment plate 81 from sliding as much as possible. Adjustment plate 81 can further reduce the distance between the two positioning boxes 707, so that positioning box 707 can restrict the position of pre-prepared dishes of different sizes.

[0059] When it is necessary to store the packaged pre-prepared food, the motor 10 is started. The output of the motor 10 rotates, which drives the reducer 9 to rotate. At this time, the output of the reducer 9 rotates the electric rotating cage 11. The rotation of the rotating cage 11 drives the chain belt 5 to move along the surface of the double helical guide rail 4. Then, the heated pre-prepared food is placed on the chain belt 5. At this time, the chain belt 5 drives the pre-prepared food spiral to move from bottom to top. During this process, the water pump 13 is started. The water inlet of the water pump 13 draws cold water from the water storage tank 1 through the water inlet pipe 15. The temperature of the cold water is 4-7℃. Then, the cold water flows through the water pump 13 and flows along the inner wall of the water delivery pipe 14. The cold water flows into the frame 2, and then flows into the annular pipe 16 and the support pipe. Within 3 seconds, the first nozzle 17 and the second nozzle 18 will discharge cold water. Since the outlet of the second nozzle 18 is tilted upwards, the water discharged from the second nozzle 18 will contact the lower surface of the pre-cooked food through the through hole. At this time, the water will cool the pre-cooked food once. Then, the water will drip due to its own gravity, and the dripping water will flow to the upper surface of the pre-cooked food below, thus cooling the upper surface of the pre-cooked food a second time. Therefore, multiple second nozzles 18 working together can simultaneously cool the upper and lower surfaces of the pre-cooked food, greatly improving the cooling speed of the pre-cooked food and making the pre-cooked food cool evenly, thus improving the cooling effect of the equipment on the pre-cooked food. By changing the opening of the V-groove 19 on the second nozzle 18... The angle of the nozzle can be adjusted to control the spray range of the second nozzle 18, allowing cold water to be sprayed more accurately onto the pre-cooked food. Since the inner wall of the second nozzle 18 is made of stainless steel, the outlet of the second nozzle 18 will not rust or become clogged, thus extending its service life. Because the inner wall of the V-groove 19 is polished, it is smooth, allowing water to flow quickly. By adjusting the running speed of the chain belt 5, the pre-cooked food can be made to fully contact with the cold water, thus cooling pre-cooked food of different volumes or weights, expanding the equipment's applicability. When the pre-cooked food moves to the top with the chain belt 5, the water discharged from the first nozzle 17 will again spray the pre-cooked food. The food is cooled down, and the first nozzle 17 can spray a solid cone-shaped stream of water. Multiple first nozzles 17 work together to form a water curtain that covers the double spiral guide rail 4. The water curtain can reduce the influence of the ambient temperature on the temperature of the pre-cooked food, thereby further improving the cooling speed of the pre-cooked food. Then the pre-cooked food will move to another chain plate belt 5, which will drive the pre-cooked food spiral to move from top to bottom. During this process, the first nozzle 17 and the second nozzle 18 will continuously cool the pre-cooked food. During the cooling process, the first nozzle 17 and the second nozzle 18 will allow the cold water to come into direct contact with the surface of the pre-cooked food, thereby improving the heat exchange efficiency between the cold water and the pre-cooked food, and further improving the cooling effect of the pre-cooked food.
