[0027] Combine the following Figures 1 to 5 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0028] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In the food industry, especially in the production of cold drinks and soups, there are strict requirements for the cooling and preservation of soups or beverages. For example, soups (including beverages, of course, the soups mentioned below are not limited to a specific type of soup, but can cover all liquid and fluid foods that need to be processed at high temperatures) still have a high temperature after cooking, and need to be cooled to a suitable temperature before filling and packaging. Figure 1 The soup is cooled by arranging cooling pipes on the outer periphery or inner wall of the cooking pot 10. After the soup is produced in the cooking pot 10, it remains in the cooking pot 10. The cooking pot 10 is cooled by passing a cooling medium through the cooling pipes. However, this cooling method has a small contact area between the cooling pipe and the soup, and the heat exchange efficiency is insufficient. Therefore, it takes a lot of time to cool the soup to the target temperature, which is not conducive to improving production efficiency.

[0031] Based on the above problems, the first aspect of the present application provides a cold soup device 100, please refer to Figure 2 The cold soup equipment 100 includes a cooking pot 10 and a heat exchanger 20. The soup after cooking is stored in the cooking pot 10. The heat exchanger 20 includes a first heat exchange side 21 and a second heat exchange side 22. The first heat exchange side 21 and the second heat exchange side 22 can exchange energy with each other. The first heat exchange side 21 is connected to the cooking pot 10, and the second heat exchange side 22 is used to pass the cooling medium. The heat exchanger 20 is detachably connected to the cooking pot 10 in a skid-mounted manner. By utilizing the mutual exchange of energy between the first heat exchange side 21 and the second heat exchange side 22 of the heat exchanger 20, the heat of the high-temperature soup in the cooking pot 10 can be transferred to the second heat exchange side 22, and the soup after cooling returns to the cooking pot 10, completing a cooling cycle. By continuously passing the soup in the cooking pot 10 into the first heat exchange side 21 for cooling, after multiple cooling cycles, the temperature of all the soups in the cooking pot 10 can be reduced to the target temperature, so that the soup can be subsequently filled and packaged. Compared with the method of arranging cooling pipes on the periphery of the cooking pot 10, the cold soup device 100 provided in the present application is to pass the soup into the heat exchange device, which can increase the contact area between the soup and the cooling medium in the heat exchange device and improve the cooling efficiency. The heat exchanger 20 is connected to the cooking pot 10 in a skid-mounted manner. On the one hand, there is no need to modify the existing cooking pot 10 and other equipment and pipelines in the existing production line, thereby improving the adaptability and versatility of the soup cooling solution. On the other hand, the heat exchanger 20 adopts a skid-mounted design, which has the advantages of compact overall structure, small footprint, easy transportation and installation, etc., which improves the convenience and practicality of the installation and use of the heat exchanger 20. For example, the skid-mounted base is provided with rollers and hoisting holes for easy rapid movement and fixation.

[0032] In some embodiments, the cooking pot 10 is provided with a liquid outlet 11 and a liquid return port 12, the liquid outlet 11 is connected to the first inlet 211 of the first heat exchange side 21, and the liquid return port 12 is connected to the second inlet 212 of the first heat exchange side 21. By using the liquid outlet 11 and the liquid return port 12, the liquid discharge process and the liquid return process of the soup in the cooking pot 10 can be carried out simultaneously, and the two processes do not affect each other, thereby improving the efficiency and reliability of the soup cooling process.

[0033] It can be understood that the first inlet 211 and the second inlet 212 of the first heat exchange side 21 are interconnected through the flow path inside the first heat exchange side 21, and the fluid (such as soup, cleaning liquid) flowing through the first heat exchange side 21 enters from either the first inlet 211 or the second inlet 212 and flows out from the other one.

[0034] Exemplarily, the heat exchanger 20 may be a plate heat exchanger 20 , and a power device such as a compressor may be used to drive the heat exchanger 20 to operate.

[0035] The present application utilizes a heat exchanger 20 to cool the soup. As the use time of the heat exchanger 20 increases, the problem of cleaning the heat exchanger 20 will also arise. On the one hand, since the heat exchanger 20 needs to have a large heat exchange area, the channels inside the heat exchanger 20 are usually arranged relatively densely, which makes it difficult to clean the inside of the heat exchanger 20. On the other hand, the heat exchanger 20 is connected to the cooking pot 10 when in use. If it is cleaned by manual spraying or the like, the heat exchanger 20 needs to be separated from the cooking pot 10, and the heat exchanger 20 needs to be connected to the cooking pot 10 again after cleaning. Therefore, this flushing cleaning method is not only difficult to ensure the cleaning effect, but also has low cleaning efficiency.

[0036] Based on this, the second aspect of the present application provides a self-cleaning device 200, see Figure 3The self-cleaning device 200 further includes a cleaning mechanism 300 on the basis of the cold soup device 100 provided in the first aspect. Specifically, the cold soup device 100 further includes a liquid outlet pipeline 110, the liquid outlet pipeline 110 is connected to the liquid outlet 11 of the cooking pot 10, and the cleaning mechanism 300 includes a cleaning pipeline 310, the liquid outlet pipeline 110 and the cleaning pipeline 310 are arranged in parallel, and the first inlet 211 of the first heat exchange side 21 is selectively connected to the liquid outlet pipeline 110 or the cleaning pipeline 310. In this way, the heat exchanger 20 can be selectively connected to the liquid outlet pipeline 110 or the cleaning pipeline 310 according to working needs or cleaning needs. With the liquid outlet pipeline 110 and the cleaning pipeline 310 arranged in parallel, when the heat exchanger 20 is working, the first inlet 211 of the first heat exchange side 21 is connected to the liquid outlet pipeline 110, and when the heat exchanger 20 is cleaned, the first inlet 211 of the first heat exchange side 21 is connected to the cleaning pipeline 310. Therefore, the heat exchanger 20 can be cleaned by simply switching the pipeline, without separating or reconnecting the heat exchanger 20 from the cooking pot 10, thereby improving the convenience of cleaning the heat exchanger 20. For example, a solution containing a detergent or hot water can be passed into the cleaning pipeline 310, and the internal flow path of the heat exchanger 20 is flushed and cleaned with the cleaning liquid or hot water to ensure that the flow path inside the heat exchanger 20 can meet the food hygiene standards.

[0037] Please also read Figure 4 and Figure 5 , Figure 4 The figure shows the flow path of the soup when the self-cleaning device 200 is cooling the soup (cooling condition), and the pipes in the dotted line portion represent a non-conducting state in this condition. Figure 5 The figure shows the flow path of the cleaning liquid or hot water in the self-cleaning state (self-cleaning working condition) of the self-cleaning device 200, and the dotted part of the pipeline indicates the non-conducting state in this working condition. In some embodiments, the cold soup device 100 includes a liquid return pipeline 120, and the liquid return pipeline 120 is connected to the liquid return port 12 of the cooking pot 10; the cleaning mechanism 300 includes a sewage pipeline 320 and a bypass pipeline 330, and the cleaning mechanism 300 includes a sewage pipeline 320 and a bypass pipeline 330, one end of the bypass pipeline 330 is connected to the cleaning pipeline 310, and the other end is connected to the second inlet 212 of the first heat exchange side 21, and the sewage pipe is connected to the first inlet 211 of the first heat exchange side 21. By setting the sewage pipeline 320 and the bypass pipeline 330, when the heat exchanger 20 is cleaned (please refer to Figure 5 ), the cleaning liquid can enter from the cleaning pipeline 310, then enter the bypass pipeline 330, and enter the first heat exchange side 21 from the second inlet 212, leave the first heat exchange side 21 from the first inlet 211, and finally be discharged from the sewage pipe. With this connection method, the sewage after cleaning can be discharged outside the heat exchanger 20 to avoid residual pollutants, thereby ensuring the cleaning effect. When the heat exchanger 20 is working (see Figure 4), the soup is output from the cooking pot 10 through the liquid outlet pipe 110, enters the first heat exchange side 21 from the first inlet 211, and leaves the heat exchange side from the second inlet 212. The soup exchanges heat with the cooling medium of the second heat exchange side 22 in the first heat exchange side 21, thereby transferring the heat to the second heat exchange side 22, thereby cooling the soup, and finally returns to the cooking pot 10 through the liquid return pipe 120, thereby realizing a cooling cycle. The scheme in this embodiment can not only realize the self-cleaning effect of the heat exchanger 20, but also when the heat exchanger 20 needs to be cleaned, it is not necessary to separate the heat exchanger 20 from the cooking pot 10, but by passing cleaning liquid or hot water into the cleaning pipe 310, the cleaning liquid can be used to flow in the pipe of the first heat exchange side 21 to clean the inside of the heat exchanger 20, thereby improving the convenience and efficiency of cleaning the heat exchanger 20, and ensuring that the heat exchanger 20 can achieve a good cleaning effect. Furthermore, by providing the bypass pipeline 330 and the sewage pipeline 320, the flow path and flow direction of the cleaning liquid are completely independent from the flow path of the soup, thereby reducing the influence of the cleaning operation on the cooling of the soup.

[0038] It is understandable that before the heat exchanger 20 is self-cleaned, the soup in the cooking pot 10 may be emptied (for example, for filling, packaging or transfer) to further ensure that the cleaning liquid and the soup do not interfere with each other.

[0039] Of course, as an alternative embodiment, when the cleaning mechanism 300 is not provided with the sewage discharge pipeline 320 and the bypass pipeline 330, the cleaning liquid can also be passed into the emptied cooking pot 10 by using the liquid return pipeline 120, so as to clean the cooking pot 10. Finally, the cleaning sewage can be discharged from the cooking pot 10.

[0040] In some embodiments, a first stop valve 301 is provided in the liquid return line 120, a second stop valve 302 is provided in the cleaning line 310, a third stop valve 303 is provided in the bypass line 330, and a fourth stop valve 304 is provided between the bypass line 330 and the sewage line 320; when the first stop valve 301 is opened, the fourth stop valve 304 is opened, and the second stop valve 302 and the third stop valve 303 are closed; when the second stop valve 302 is opened, the third stop valve 303 is opened, and the first stop valve 301 and the fourth stop valve 304 are closed. By setting the opening and closing of each stop valve, it is ensured that the soup or cleaning liquid can flow in the set flow direction, and the self-cleaning device 200 can be stably operated.

[0041] In some embodiments, a fifth stop valve 305 is provided in the sewage pipeline 320, and a sixth stop valve 306 is provided in the liquid return pipeline 120; when the first stop valve 301 is opened, the sixth stop valve 306 is opened, and the fifth stop valve 305 is closed; when the second stop valve 302 is opened, the fifth stop valve 305 is opened, and the sixth stop valve 306 is closed. By providing the fifth stop valve 305, in coordination with the second stop valve 302 and the third stop valve 303, the cleaning passage is connected, and the effect of cleaning the inside of the heat exchanger 20 is achieved. By providing the sixth stop valve 306, in coordination with the first stop valve 301 and the fourth stop valve 304, the passage for cooling the soup is realized, and the effect of cooling the soup is achieved.

[0042] In some embodiments, the self-cleaning device 200 further includes a control structure (not shown), the first stop valve 301, the second stop valve 302, the third stop valve 303, the fourth stop valve 304, the fifth stop valve 305 and the sixth stop valve 306 are all electronic valves, and the control structure is electrically connected to the first stop valve 301, the second stop valve 302, the third stop valve 303, the fourth stop valve 304, the fifth stop valve 305 and the sixth stop valve 306 to control the opening or closing of the stop valve. By setting the control structure to control the opening and closing of the above-mentioned stop valves, the switching of the two flow paths of the heat exchanger 20 operation and the internal cleaning of the heat exchanger 20 can be realized, thereby realizing the function of automatic cleaning of the heat exchanger 20 and improving the intelligence of the cleaning operation of the heat exchanger 20.

[0043] In some embodiments, the cleaning device further includes a temperature sensor 307, which is disposed in at least one of the liquid outlet pipeline 110 and the liquid return pipeline 120. The temperature sensor 307 is electrically connected to the control structure, and the control structure can also be used to control the opening and closing of the first stop valve 301 according to the detected temperature of the temperature sensor 307. By providing the temperature sensor 307, it can be used to detect the temperature of the soup in real time, so that the cooling cycle of the soup can be continued according to the temperature of the soup, or the soup cooling can be stopped when the soup is cooled to the target temperature, thereby reducing the energy consumption of the heat exchanger 20.

[0044] In some embodiments, the cold soup device 100 further includes a circulation pump 308, which is disposed in the liquid outlet pipeline 110. The circulation pump 308 can extract the soup in the cooking pot 10 into the liquid outlet pipeline 110, provide power for the cooling circulation of the soup, and facilitate adjustment of the flow rate and cooling speed of the soup. It is understandable that the circulation pump 308 can be electrically connected to the control structure, and the flow rate of the circulation pump 308 can be controlled by the control structure.

[0045] Optionally, a flow valve 309 may also be provided in the second heat exchange side 22 to control the flow of the cooling medium. The flow valve 309 may be electrically connected to the control structure, and the cooling rate may be adjusted by adjusting the flow valve 309 .

[0046] The following is an explanation of the two processes of the self-cleaning device 200, namely, cooling the soup and performing self-cleaning.

[0047] See also Figure 4 When the self-cleaning device 200 is used to cool the soup, the control structure controls the first stop valve 301, the fourth stop valve 304 and the sixth stop valve 306 to open, and the other stop valves are closed. At this time, the first inlet 211 of the first heat exchange side 21 is connected to the liquid outlet pipeline 110. The circulation pump 308 is turned on, and the soup is pumped out from the cooking pot 10 into the liquid outlet pipeline 110 by the power of the circulation pump 308. The soup enters the first heat exchange side 21 from the first inlet 211 through the liquid outlet pipeline 110, and leaves the first heat exchange side 21 from the second inlet 212. At this time, the soup flows in the first heat exchange side 21 along the arrow direction, and the soup exchanges heat with the cooling medium in the second heat exchange side 22 in the first heat exchange side 21, thereby transferring heat to the second heat exchange side 22, realizing the cooling of the soup, and the soup returns to the cooking pot 10 through the return liquid pipeline 120.

[0048] See also Figure 5 When the self-cleaning device 200 is self-cleaning, the control structure controls the second stop valve 302, the third stop valve 303 and the fifth stop valve 305 to be opened, and the other stop valves are closed. At this time, the first inlet 211 of the first heat exchange side 21 is connected to the cleaning pipeline 310, and the cleaning liquid or hot water provided from the outside enters the cleaning pipeline 310, and the cleaning liquid or hot water enters the bypass pipeline 330, and then enters the first heat exchange side 21 from the second inlet 212, and leaves the first heat exchange side 21 from the first inlet 211. At this time, the cleaning liquid flows in the direction of the arrow on the first heat exchange side 21 (opposite to the flow direction under the cooling condition), and is finally discharged through the sewage pipeline 320, thereby achieving the self-cleaning effect of the pipeline on the first heat exchange side 21.
