Description

Technical Field

[0001] The present invention belongs to the technical field of cooling equipment, and in particular relates to a soup cooling system and a cooling method thereof. Background Art

[0002] In restaurant or hotel systems, soups generally need to be served on the table immediately after processing. Once the best drinking period is missed, the soup will lose its original taste.

[0003] To accelerate the cooling of soup and shorten its cooling time, existing soups are typically cooled after production by air cooling, water cooling, or placing them in an air-conditioned room. Generally, when air cooling is used to cool large volumes of soup, a large amount of heat is generated during the cooling process. This heat cannot be dissipated promptly indoors, affecting the working environment of the staff. Furthermore, bacteria can easily enter the soup during the airflow, affecting the quality of the soup. Water cooling wastes a large amount of water resources and has low cooling efficiency. Cooling in an air-conditioned room consumes a large amount of electricity, and using air conditioning to cool hot soup inevitably damages the air conditioner. Therefore, regardless of which of the above methods is used to cool large volumes of soup, there are certain drawbacks.

[0004] In order to overcome the problem of water resource waste caused by the existing water-cooled cooling of soup, a soup cooling device is provided in the prior art, including a bracket, a lifting plate, a refrigeration box, a cooling pipe, a motor, a stirring barrel and a fixed barrel. The fixed barrel is fixed to the bottom of the bracket, the cooling pipe is spirally wound on the surface of the fixed barrel, the water inlet and outlet of the cooling pipe are both connected to the refrigeration box, the lifting plate is slidably connected to the bracket, the stirring barrel is located above the fixed barrel and is threadedly connected to the lifting plate, the motor is fixed on the lifting plate, and a stirring blade is fixed to the driving end of the motor, and the stirring blade is located inside the stirring barrel.

[0005] During operation, the soup to be cooled is injected into the mixing barrel, the lifting plate descends to drive the mixing barrel into the interior of the fixed cylinder, the motor starts to drive the stirring blades to stir the soup, and the refrigeration box inputs cooling water into the cooling pipe. The cooling water circulates and takes away the heat of the soup, thereby cooling the soup.

[0006] Although the soup cooling device circulates the cooling water through the refrigeration box and the cooling pipe when cooling the soup, so that water resources can be recycled, there are the following problems with using this device to cool the soup. First, the refrigeration box consumes a lot of electricity when cooling the returning cooling water, resulting in a waste of other energy sources; second, there is a gap between the cooling water and the soup, resulting in a low cooling efficiency of the soup; third, the mixing barrel and the lifting plate are threadedly connected, which causes certain difficulties in the injection of soup and the installation between the mixing barrel and the lifting plate; in addition, when the soup fills the mixing barrel, the lifting plate will be subjected to a large pulling force, resulting in a large amount of power loss, which greatly increases the cooling cost of the soup.

[0068] In one embodiment of the present invention, Figure 1 and 7 As shown, a soup cooling system is provided, including a chiller 10, a cooling tower 20 and a cooling device 30, wherein the cooling device 30 includes a cooling box 31, a cooling sealed cavity 311 is provided inside the cooling box 31, and a water inlet 312 and a water outlet 313 are provided on the cooling box that are connected to the cooling sealed cavity 311. The cooling tower 20 is located on one side of the cooling box 31, and a return port 211, a water inlet 212, a return port 213 and a water supply port 214 are provided on the cooling tower 20. The return port 211 is connected to the water outlet 313. The water supply port 214 is connected to the water inlet 312, and the chiller 10 is located on one side of the cooling tower 20 and is connected to the interior of the cooling tower 20 through the water inlet 212 and the return water port 213. The cooling tower 20 is used to cool the hot water entering the interior of the cooling tower 20 from the water outlet 313 to form primary cooling water. The chiller 10 is used to input cooling water to the cooling tower 20 from the water inlet 212, and to perform secondary cooling on the primary cooling water entering the chiller 10 from the return water port 213 of the cooling tower 20.

[0069] Specifically, the cooling system includes a chiller 10, a cooling tower 20 and a cooling device 30. The cooling device 30 includes a cooling box 31. The cooling box 31 is provided with a cooling sealed cavity 311. The cooling box is provided with a water inlet 312 and a water outlet 313. The cooling tower 20 is provided with a return port 211, a water inlet 212, a return water port 213 and a water supply port 214. The return port 211 is connected to the water outlet 313, and the water supply port 214 is connected to the water inlet 312. The chiller 10 is located on one side of the cooling tower 20 and is connected to the interior of the cooling tower 20 through the water inlet 212 and the return water port 213. When the soup is cooled, cold water is first injected into the water tank of the chiller 10. The chiller 10 refrigerates the cold water to form cooling water, and the cooling barrel 70 filled with hot soup is placed Enter the cooling sealed chamber 311, start the water pump, and the cooling water enters the cooling tower 20 from the chiller 10 through the water inlet 212 of the cooling tower 20, and enters the cooling sealed chamber 311 from the cooling tower 20 through the water supply port 214 and the water inlet 312 in sequence. The cooling water flows and rises in the cooling sealed chamber 311 and absorbs heat from the hotter soup in the cooling barrel 70 to form hot water. After the hot water rises to a certain level, it enters the cooling tower 20 from the water outlet 313 and the return port 211 in sequence. The cooling tower 20 cools the hot water once to form primary cooling water. The primary cooling water enters the chiller 10 from the return port 213 for secondary cooling. The secondary cooled cooling water enters the cooling tower 20 from the water inlet 212 again for another cooling cycle until the cooling of the soup is completed. By having the cooling water formed by the chiller 10 flow on the surface of the barrel arm of the cooling barrel 70 filled with hot soup and directly contacting it, the heat dissipation efficiency of the soup can be effectively improved; the hot water formed is cooled by the cooling tower 20 and the chiller 10 to form cooling water again, which can realize the recycling of water resources and effectively reduce the water cost of the cooling process; the hot water is cooled once by the cooling tower 20 and then cooled for a second time by the chiller 10. Since the chiller 10 consumes a lot of electricity during the cooling process, the hot water is first cooled once by the cooling tower 20 to reduce a part of the water temperature and then cooled for a second time by the chiller 10. This can effectively reduce the electricity consumed in the cooling process of the hot water, and ultimately achieve the purpose of low cost and high cooling efficiency.

[0070] In this embodiment, further, Figure 2 As shown, the cooling box 31 is provided with a box overflow port 314, which is located above the water outlet 313. Specifically, after the cooling barrel 70 is placed in the cooling sealed chamber 311, the height of the box overflow port 314 is lower than the height of the barrel opening of the cooling barrel 70, preventing the water level in the cooling sealed chamber 311 from being too high and seeping into the cooling barrel 70.

[0071] In this embodiment, further, Figure 1As shown, the water inlet 312 and the water supply port 214, the water outlet 313 and the return port 211, the water inlet 212 and the chiller 10, and the return port 213 and the chiller 10 are all connected by pipes 12. The pipes between the water inlet 312 and the water supply port 214, and the water outlet 313 and the return port 211 are all provided with water pumps (not marked in the figure). The cooling water flows from the chiller 10 into the cooling tower 20 and the cooling box by the water pump between the water inlet 312 and the water supply port 214. The cooling water flows from the cooling box back to the cooling tower 20 and the chiller 10 by the water pump between the water outlet 313 and the return port 211.

[0072] In this embodiment, a detector (not shown) for detecting the soup temperature is further provided in the cooling sealed chamber 311. When the soup temperature detector detects that the soup temperature has reached a set value, the water pump between the water inlet 312 and the water supply port 214 stops operating, and the water pump between the water outlet 313 and the return port 211 starts operating, sucking the water out of the cooling sealed chamber 311.

[0073] In this embodiment, further, Figures 1 to 3 As shown, the surface of the cooling box 31 is provided with soup heat dissipation holes 315 communicating with the cooling sealed cavity 311 .

[0074] In this embodiment, further, the chiller 10 includes a casing 11, and a compressor, an expansion valve, a water tank, a cooling fan, a condenser and an evaporator (not marked in the figure) fixed in the casing 11; when the chiller 10 is working, the low-temperature and low-pressure refrigerant gas after evaporation and cooling is sucked into the compressor, and then compressed into a high-temperature and high-pressure gas and sent to the condenser; the high-pressure and high-temperature gas is cooled by the condenser to condense the gas into a normal-temperature and high-pressure liquid; when the normal-temperature and high-pressure liquid flows into the thermal expansion valve, it is throttled into a low-temperature and low-pressure wet steam and flows into the evaporator, and the low-temperature liquid refrigerant enters the evaporator to absorb heat from the cooling water in the water tank, and the cooling fan assists the refrigerant in dissipating heat from the cooling water, so that the temperature of the water in the water tank is reduced, and the evaporated refrigerant is sucked back into the compressor, and the next refrigeration cycle is repeated, thereby achieving the purpose of refrigeration.

[0075] In another embodiment of the present invention, Figures 1 to 4As shown, the cooling device 30 also includes a transport mechanism 40, which includes a transport frame 41 and a transport trolley 42.

The sealed box door is hinged to the cooling box 31, and a sealing rubber ring (not marked in the figure) is provided on the surrounding side of the cooling inlet 316. When the sealed box door 317 is closed, the sealed box door 317 fits the sealing rubber ring. The transport frame 41 is located on one side of the cooling inlet 316, and a first support frame 318 is provided on the bottom wall of the cooling sealed cavity 311. The surface of the first support frame 318 is provided with a first transport rail 319, and the top of the transport frame 41 is provided with a second transport rail 411. The first transport rail 319 and the second transport rail 411 are docked, and the transport trolley 42 is rollingly connected to the surface of the first transport rail 319 and the second transport rail 411 and is used to transport the soup.

[0076] Specifically, when cooling the soup, the cooling barrel 70 is placed on the transport vehicle 42 and the soup is injected. The cooling barrel 70 carrying the soup is transported by the transport vehicle 42 from the cooling inlet 316 to the cooling sealed chamber 311 and fixed on the first transport rail 319. It is supported by the first support frame 318, and the sealed box door 317 is closed. The inner side of the sealed box door 317 fits with the sealing rubber ring to achieve sealing of the cooling inlet 316. On the one hand, the first support frame 318 can support the cooling barrel 70, and on the other hand, it can support the cooling barrel 70 so that the bottom surface of the cooling barrel 70 can be in contact with the cooling water, thereby improving the cooling efficiency of the soup.

[0077] In this embodiment, further, Figures 4-6 As shown, a drain rack 32 is provided on one side of the cooling box 31 located at the cooling inlet 316. The drain rack 32 is located below the cooling inlet 316. A drainage groove 321 is provided on the surface of the drain rack 32. The length of the drainage groove 321 is greater than the bottom length of the cooling inlet 316. A drainage pipe 322 is provided on the bottom surface of the drain rack 32, which is connected to the drainage groove 321. Specifically, the drain rack 32 prevents water seepage from the cooling inlet 316 and promptly drains any water that seeps from the cooling inlet 316. Furthermore, the drain rack 32 receives water that flows out of the sealed door 317 when the sealed door is opened. The water that flows into the drainage groove 321 eventually flows down the drainage pipe 322 and is stored, thus avoiding water waste.

[0078] In this embodiment, further, Figures 1 to 4 As shown, a limiting frame 33 is provided around the cooling inlet 316 , and the sealing rubber ring is fixed on the limiting frame 33 .

[0080] Specifically, when cooling the soup, the cooling barrel 70 is fixed on the barrel body limiting frame 422 on the support plate 425, and is limited by the limiting ring 4221 and the connecting bar 4222. The first transport wheel 423 can facilitate the rolling of the transport vehicle 42 on the surface of the first transport rail 319 and the second transport rail 411. The first transport wheel 423 can be limited on both sides of the first transport rail 319 and the second transport rail 411 to improve the stability of the transport vehicle 42. The water seepage cooling hole 4251 can facilitate the contact between the cooling water and the bottom surface of the cooling barrel 70, thereby effectively improving the cooling efficiency of the soup.

[0081] In another embodiment of the present invention, Figures 1 to 4 As shown, a second transport wheel 412 is provided at the bottom of the transport rack 41, a transverse reinforcement rib 413 and a longitudinal reinforcement rib 414 are provided at the middle part of the transport rack 41, a transport handle 415 is provided at the end of the transport rack 41, a reinforcement plate 416 is fixed between the water seepage transport handle 415 and the water seepage transport rack 41, and a docking opening 417 is provided at one end of the first transport rail 319 and the second transport rail 411 that are docked with each other, and the width of the docking opening 417 is greater than the width of the first transport rail 319 and the second transport rail 411, and two limit blocks 34 are provided on the bottom side of the cooling inlet 316, and the two limit blocks 34 are arranged opposite to each other and are respectively located on both sides of the transport rack 41.

[0082] Specifically, the longitudinal reinforcement ribs 414 and the transverse reinforcement ribs 413 can enhance the pressure-bearing capacity of the transport rack 41, and the reinforcement plate 416 can enhance the connection between the transport handle 415 and the transport rack 41. Since the second transport wheel 412 is provided at the bottom of the transport rack 41, after the cooling barrel 70 is placed in the sealed cooling box 31, the transport rack 41 can be pushed out by the second transport wheel 412, which facilitates the closing of the sealed box door 317 and provides convenience for the injection of soup into the cooling barrel 70. The docking opening 417 and the limit block 34 can facilitate the pushing of the transport rack 41 and the docking of the first transport rail 319 and the second transport rail 411.

[0083] In another embodiment of the present invention, Figures 1 to 6 As shown, the cooling box 31 is also provided with a locking assembly 50, and the locking assembly 50 includes a threaded connecting frame 51, a screw 52, a turntable 53 and two limit plates 54. The threaded connecting frame 51 is fixed to the cooling box 31 on the side of the cooling inlet 316 away from the hinged end of the sealed box door 317, and the screw 52 is threadedly connected to the inside of the threaded connecting frame 51. The turntable 53 is fixed to the end of the screw 52. A handle 55 is provided on the surface of the turntable 53. The two limit plates 54 are arranged opposite to each other and fixed to the sides of the sealed box door 317. When the sealed box door 317 is closed, the two limit plates 54 are respectively located on both sides of the screw 52.

[0084] Specifically, when the sealed box door 317 is closed, the two limit plates 54 are located on both sides of the screw 52. The screw 52 can be tightened by rotating the turntable 53, and the side of the turntable 53 close to the limit plate 54 is abutted against the limit plate 54 to achieve the locking of the sealed box door 317. Through the above locking method, the locking force of the sealed box door 317 can be conveniently adjusted, the sealing performance of the sealed box door 317 can be improved, and the opening and closing of the sealed box door 317 can be facilitated.

[0085] In another embodiment of the present invention, Figure 4 As shown, the cooling device 30 also includes a stirring mechanism 60, which includes a first stirring component 61 and a stirring motor 62. A base fixing frame 3111 is provided inside the cooling sealed cavity 311, and the stirring motor 62 is fixed on the base fixing frame 3111. The first stirring component 61 includes a rotating shaft 611, a stirring shaft 612, a stirring blade 613 and a sealing barrel cover 614. The rotating shaft 611 is vertically arranged and fixed on the driving end of the stirring motor 62. The stirring shaft 612 is fixedly connected to the rotating shaft 611 through a coupling 615. The stirring blade 613 and the sealing barrel cover 614 are both fixed on the surface of the stirring shaft 612, and the sealing barrel cover 614 is located above the stirring blade 613.

[0086] Specifically, before the cooling barrel 70 is pushed into the cooling sealed cavity 311, the stirring shaft 612 is first removed from the rotating shaft 611 to prevent the stirring shaft 612 from blocking the pushing of the cooling barrel 70. After the cooling barrel 70 is pushed into the cooling sealed cavity 311, the stirring shaft 612 is reinstalled, and the sealed barrel cover 614 is covered on the barrel mouth of the cooling barrel 70 to prevent cooling water from splashing into the cooling barrel 70 or the soup from leaking. During cooling, the stirring motor 62 starts to drive the rotating shaft 611 and the stirring shaft 612 to rotate, stirring the soup, accelerating the cooling of the soup, and effectively improving the cooling efficiency of the soup.

[0087] In another embodiment of the present invention, Figure 4 As shown, the first stirring component 61 also includes a worm gear fixing seat 616 and a worm shaft 617. The worm gear fixing seat 616 is fixed on the machine base fixing frame 3111 and is located on one side of the stirring motor 62. The worm shaft 617 passes through the worm gear fixing seat 616 and is fixed on the machine shaft of the stirring motor 62. The rotating shaft 611 is transmission-connected to the worm shaft 617. The stirring mechanism 60 also includes a second stirring component 63 with the same structure as the first stirring component 61. The worm gear fixing seat 616 of the second stirring component 63 is fixed on the machine base fixing frame 3111, and the worm shaft 617 of the second stirring component 63 is fixedly connected to the worm shaft 617 of the first stirring component 61 through a coupling 615.

[0088] Specifically, through the above arrangement, when the stirring motor 62 is in operation, it can simultaneously drive the stirring shafts 612 of the first stirring component 61 and the second stirring component 63 to rotate, thereby simultaneously stirring the two cooling barrels 70 and improving the cooling efficiency of the soup.

[0089] In this embodiment, further, the number of the barrel limiting frames 422 is two.

[0090] In another embodiment of the present invention, Figure 2 As shown, a water retaining frame 364 is fixed to the inner wall of the cooling sealed chamber 311. The water retaining frame 364 is fixed to one side of the water inlet 312. A vertical water retaining plate 361 is provided around the water retaining frame 364. An inclined buffer slope 362 is provided at the top of the water retaining frame 364. A water inlet opening 363 is provided at the bottom of the water retaining frame 364. Specifically, the water retaining frame 364 can block and buffer the cooling water entering the cooling sealed chamber 311, facilitate the introduction of the cooling water, and prevent the cooling water from flowing into the cooling barrel 70.

[0091] In another embodiment of the present invention, Figure 1 and 7As shown, the cooling tower 20 includes a tower body 21, a cooling fan 22, a diverter plate 23, a partition plate 24 and an insulation liner 25. The partition plate 24 is horizontally fixed to the inside of the tower body 21. The upper and lower sides of the partition plate 24 are respectively provided with a heat dissipation cavity 241 and a water storage cavity 242. The insulation liner 25 is fixed in the water storage cavity 242. The return water port 213, the water inlet 212 and the water supply port 214 are all connected to the insulation liner 25. The return water port 211 is connected to the heat dissipation cavity 241. The partition plate 24 is provided with an inner liner water inlet pipe 243, and the inner liner water inlet pipe 243 is connected to the inside of the insulation liner 25. The tower body 21 is connected, and a tower overflow port 215 is provided on the surface of the tower body 21. The tower overflow port 215 is connected with the interior of the thermal insulation liner 25. The cooling fan 22 is fixed on the top of the cooling cavity 241. The diverter plate 23 is horizontally fixed in the cooling cavity 241 and is located below the return port 211. A plurality of diverter holes 231 are provided on the surface of the diverter plate 23 at intervals. A plurality of rows of cooling water heat dissipation holes 216 are provided on the side wall of the cooling cavity 241 at intervals. A water retaining inclined plate 217 is fixed above each row of the cooling water heat dissipation holes 216, and the water retaining inclined plate 217 extends toward the direction of the partition plate 24.

[0092] Specifically, when working, the cooling fan 22 is started, and hot water is pumped into the heat dissipation cavity 241 from the return port 211, flows into the diverter plate 23 and is dispersed, and flows down from the diverter hole 231, and finally flows out of the interior of the thermal insulation liner 25 from the liner water inlet pipe 243. During the flow of hot water, the heat dissipation of the cooling fan 22, the diversion of the diverter plate 23 and the heat dissipation of the cooling water heat dissipation hole 216 can increase the cooling efficiency of the cooling water and reduce the energy consumption of the chiller 10. The water retaining inclined plate 217 can prevent the cooling water from flowing out of the cooling water heat dissipation hole 216 to the outside of the heat dissipation cavity 241.

[0093] In this embodiment, the cooling tower 20 is further provided with a cooling water temperature detector (not shown) for detecting the water temperature of the heat-insulating inner tank 25. When the cooling water temperature detector detects that the cooling water temperature in the heat-insulating inner tank 25 reaches a predetermined value, the chiller 10 stops operating. This not only reduces power loss, but also prevents the cooling water temperature from being too low, which could cause the soup to cool excessively and affect its taste.

[0094] In one embodiment of the present invention, a soup cooling method of a soup cooling system is provided, such as Figure 8 As shown, the following steps are included:

[0095] S100: Cold water is injected into the water tank of the chiller 10, and the chiller 10 cools the cold water to form cooling water.

[0096] S200: Place the cooling barrel 70 filled with hot soup into the cooling sealed chamber 311.

[0097] S300: Start the water pump, and the cooling water enters the cooling tower 20 from the chiller 10 through the water inlet 212 of the cooling tower 20, and enters the cooling sealed cavity 311 from the cooling tower 20 through the water supply port 214 and the water inlet 312 in sequence.

[0098] S400: The cooling water flows upward in the cooling sealed chamber 311 and absorbs heat from the hot soup in the cooling barrel 70 to form hot water.

[0099] S500: After the generated hot water rises to a certain amount, it enters the cooling tower 20 from the water outlet 313 and the return port 211 in sequence.

[0100] S600: The cooling tower 20 cools the hot water once to form primary cooling water.

[0101] S700: The primary cooling water enters the chiller 10 from the return water inlet 213 for secondary cooling.

[0102] S800: The cooling water after secondary cooling enters the cooling tower 20 again from the water inlet 212 for another cooling cycle until the cooling of the soup is completed.

[0103] Specifically, through the above cooling method, the cooling water formed by the chiller 10 flows on the surface of the barrel arm of the cooling barrel 70 filled with hot soup and directly contacts it, which can effectively improve the heat dissipation efficiency of the soup; the hot water formed is cooled by the cooling tower 20 and the chiller 10 to form cooling water again, which can realize the recycling of water resources and effectively reduce the water cost of the cooling process; the hot water is cooled once by the cooling tower 20 and then cooled for the second time by the chiller 10. Since the chiller 10 consumes a lot of electricity during the cooling process, the hot water is first cooled once by the cooling tower 20 to reduce part of the water temperature and then cooled for the second time by the chiller 10. This can effectively reduce the electricity consumed in the cooling process of the hot water, and ultimately achieve the purpose of low cost and high cooling efficiency.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
