Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8As shown, a two-stage cooling mechanism includes two cooling tanks arranged one in front of the other, filled with cooling water. A drive mechanism is arranged between the two cooling tanks. A circulation mechanism is arranged on one side of each cooling tank. Each cooling tank includes a cooling box 101, the length of which is determined by actual conditions. A second water inlet 106 is opened at the front end of one side of the cooling box 101, and a first water inlet 105 is opened at the rear end of one side of the cooling box 101. The circulation mechanism includes a first pipe 301, with both ends of the first pipe 301 sealed and fixedly connected to the two second water inlets 106 respectively. A water pump assembly 304 is sealed and fixedly connected to the middle of the first pipe 301 through a connecting pipe. A second pipe 302 is arranged on one side of the first pipe 301, with both ends of the second pipe 302 connected to the two cooling boxes 106 respectively. A first water inlet 105 is sealed and fixedly connected. A filter assembly 303 is sealed and fixedly connected to the second pipe 302 via a connecting pipe. The filter assembly 303 is existing technology, and its specific structure will not be described in detail. The filter assembly 303 filters the water during water circulation, thereby ensuring the cleanliness of the water. Another water pump assembly 304 is sealed and fixedly connected to the second pipe 302 via a connecting pipe. The two water pump assemblies 304 are arranged correspondingly. The water pump assemblies 304 are existing technology, and their specific structure will not be described in detail. The two water pump assemblies 304 pump water in opposite directions, providing power for water circulation. A cooling refrigerator 305 is sealed and fixedly connected to the second pipe 302 via a connecting pipe. The cooling refrigerator 305 is existing technology. The specific structure will not be described in detail. Several staggered baffles 306 are fixedly connected inside the cooling refrigerator 305. Cooling pipes are installed inside each baffle 306. The multiple baffles 306 increase the water flow time within the cooling refrigerator 305, thus ensuring the cooling effect. A one-way valve 307 is fixedly connected to one end of the second pipe 302. The one-way valve 307 ensures the direction of water circulation. To achieve cooling of the bagged beef broth, two sets of cooling tanks are used to continuously cool the bagged beef broth with water. The water temperature in the front cooling tank 101 is lower, while the water temperature in the rear cooling tank 101 is close to room temperature. A circulation mechanism is installed to ensure stable water temperature in both cooling tanks 101. The cooling refrigerator 305 within the circulation mechanism can circulate the water. The device employs a two-stage cooling system. Upon completion of the filling and packaging of the bagged beef broth, which is at a relatively high temperature, it falls into the rear cooling tank 101. At this point, the surrounding water temperature should be as close as possible to the temperature of the bagged beef broth to avoid the negative impact of sudden cooling on the packaging bag and the broth. The bagged beef broth then moves forward, during which the surrounding water temperature gradually decreases, cooling the broth. Afterward, the bagged beef broth enters the front cooling tank 101. At this point, the temperature of the broth has already decreased, so even if the water temperature around the rear of the cooling tank 101 is lower, there will be no negative impact from sudden cooling. Thus, the rear of the cooling tank 101 has the lowest temperature, rapidly cooling the bagged beef broth. Subsequently, during its movement, the surrounding ice water absorbs heat.The chilled water, cooled by the refrigerator 305, enters the front cooling tank 101 through the first inlet 105. After cooling the bagged beef broth, it exits the front cooling tank 101 through the second inlet 106 and flows through the first pipe 301 into the rear cooling tank 101 through the second inlet 106. As the water flows forward, it absorbs heat, reaching its highest temperature at the rear of the cooling tank 101, and then exits the rear cooling tank 101 through the first inlet 105 into the second pipe 302. This circulation mechanism provides two-stage cooling of the cooling water, ensuring effective cooling. The inlet and outlet design also divides the cooling water into different temperature zones, achieving better cooling of the bagged beef broth and efficiently utilizing the water's heat absorption capacity to reduce energy consumption.

[0030] The cooling tank also includes an insulated outer shell 102 that covers the outside of the cooling box 101 and is bolted to it. The space between the insulated outer shell 102 and the cooling box 101 is filled with insulation material. A chain conveyor belt 103 is installed inside the cooling box 101. The chain plates on the chain conveyor belt 103 have several water-permeable holes. Several evenly distributed baffles 104 are fixedly connected to the chain conveyor belt 103. The chain conveyor belt 103 is U-shaped, with the front end of the chain conveyor belt 103 higher than the rear end, so that the bagged beef soup can be transported on the front and rear chain conveyor belts 103. Two symmetrically arranged top guard plates 107 are fixedly connected to the top of the cooling box 101. The top guard plates 107 prevent external factors from interfering with the cooling box 101. The two chain conveyor belts 103 carry the bagged beef soup and move within the two cooling boxes 101.

[0031] The water pump assembly 304 adopts the form of an impeller pump. A connecting support plate 308 is fixedly connected between the two water pump assemblies 304. A first bevel gear 309 is rotatably connected to the connecting support plate 308. Two symmetrically arranged second bevel gears 310 mesh on both sides of the first bevel gear 309. The second bevel gears 310 are fixedly connected to the pump body shafts of the two water pump assemblies 304 respectively. When the pump body shaft in one water pump assembly 304 rotates, it drives the second bevel gear 310 to rotate. The second bevel gear 310 drives the first bevel gear 309 to rotate. The first bevel gear 309 drives the other second bevel gear 310 to rotate in the opposite direction. The second bevel gear 310 drives the pump body shaft in the other water pump assembly 304 to rotate in the opposite direction. In this way, the two water pump assemblies 304 can provide power for water circulation.

[0032] The drive mechanism includes a fixed bracket 201 fixedly connected to two cooling boxes 101. A motor 202 is fixedly connected to the fixed bracket 201. A circulating power shaft 203 is rotatably connected to one side of the fixed bracket 201. The output end of the motor 202 is fixedly connected to the circulating power shaft 203. The other end of the circulating power shaft 203 is fixedly connected to the pump body shaft of the water pump assembly 304. A conveying power shaft 204 is rotatably connected to the top of the fixed bracket 201. A drive gear 205 is fixedly connected to the circulating power shaft 203. A driven gear 206 is fixedly connected to the conveying power shaft 204. The drive gear 205 and the driven gear 206 mesh. A drive pulley 207 is fixedly connected to the other end of the conveying power shaft 204. A first driven pulley 208 is fixedly connected to one end of the power shaft at the rear end of the front chain conveyor belt 103. The drive pulley 207 and the first driven pulley 208 are connected by a synchronous belt. The drive pulley 207 is connected to the first driven pulley 208 at the front end of the rear chain conveyor belt 103. A second driven pulley 209 is fixedly connected to one end of the force shaft. The first driven pulley 208 and the second driven pulley 209 are connected by a synchronous belt. The motor 202 drives the circulating power shaft 203 to rotate. The circulating power shaft 203 drives the pump body shaft on one side of the water pump assembly 304 to rotate. At the same time, the circulating power shaft 203 drives the drive gear 205 to rotate. The drive gear 205 drives the driven gear 206 to rotate. The driven gear 206 drives the conveying power shaft 204 to rotate. The conveying power shaft 204 drives the first driven pulley 208 to rotate. The first driven pulley 208 drives the front chain plate conveyor belt 103 to move. The first driven pulley 208 drives the second driven pulley 209 to rotate. The second driven pulley 209 drives the rear chain plate conveyor belt 103 to move. Thus, while the chain plate conveyor belt 103 is moving the bagged beef soup, the water pump assembly 304 rotates, and the water pump assembly 304 drives the water to circulate.

[0033] Several temperature sensors 108 are installed inside the cooling tank 101. The temperature sensors 108 are electrically connected to the cooling refrigerator 305. The temperature sensors 108 detect the water temperature inside the cooling tank 101. When the water temperature is too high, an electrical signal is generated to make the cooling refrigerator 305 enhance its effect, thereby realizing the monitoring and adjustment of water temperature.

[0034] Working principle: After the bagged beef broth has been filled and sealed, it is at a high temperature and falls onto the rear chain conveyor belt 103. The motor 202 drives the circulating power shaft 203 to rotate, which in turn drives the pump body shaft on the side water pump assembly 304 to rotate. Simultaneously, the circulating power shaft 203 drives the drive gear 205 to rotate, which in turn drives the driven gear 206 to rotate. The driven gear 206 drives the conveyor power shaft 204 to rotate, which in turn drives the first driven pulley 208 to rotate. The first driven pulley 208 drives the front chain conveyor belt 103 to move. The driving pulley 208 drives the second driven pulley 209 to rotate, which in turn drives the rear chain conveyor belt 103 to move. As the chain conveyor belt 103 moves the bagged beef broth, the water pump assembly 304 rotates, circulating water. The two chain conveyor belts 103 carry the bagged beef broth within the two cooling tanks 101. At this time, the water temperature at the rear end of the rear cooling tank 101 should be closest to the temperature of the bagged beef broth to avoid the negative impact of sudden cooling on the packaging bag and the beef broth. Subsequently, the chain conveyor belt 103 moves the bagged beef broth forward. During this process, the surrounding water temperature gradually decreases, cooling the bagged beef broth. The bagged beef broth then enters the front cooling tank 101. Since the temperature of the bagged beef broth has already decreased, even if the water temperature around the rear of the cooling tank 101 is lower, there will be no negative impact from a sudden drop in temperature. Thus, the rear of the cooling tank 101 has the lowest temperature, rapidly cooling the bagged beef broth. Subsequently, during its movement, the surrounding ice water absorbs heat. The ice water cooled by the cooling refrigerator 305 enters the front cooling tank 101 through the first water inlet 105, and then, after cooling the bagged beef broth, it flows out through the second water inlet... Water 106 leaves the front cooling tank 101 and enters the rear cooling tank 101 through the first pipe 301 and the second water inlet 106. As the water flows forward, it absorbs heat and reaches the highest temperature at the rear end of the cooling tank 101. It then leaves the rear cooling tank 101 through the first water inlet 105 and enters the second pipe 302. This circulation mechanism can perform two-stage cooling of the cooling water, thereby ensuring the cooling effect. The design of the inlet and outlet allows for the division of the cooling water temperature zone, achieving a better cooling effect for the packaged beef soup and efficiently utilizing the heat absorption capacity of water to reduce energy consumption.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
