Description

Technical Field

[0001] This application relates to the field of heat circulation technology, and in particular to an energy-saving system for recycling waste heat from yak milk production. Background Technology

[0002] Yak milk, rich in protein, amino acids, and other nutrients, is known as "natural concentrated milk." It is not only an indispensable part of the daily diet of people of all ethnic groups in the high-altitude regions, but also a core raw material for the local dairy processing industry. To ensure the safety of yak milk for consumption, high-temperature sterilization is an essential step in the production process. This process effectively and thoroughly kills any pathogens and other harmful microorganisms that may be present in the milk, fundamentally preventing spoilage caused by bacterial growth and thus building a strong defense for consumers' health.

[0003] Currently, the dairy processing industry generates a large amount of waste heat during the high-temperature sterilization process. This waste heat is usually discharged into the environment through cooling towers or directly, which easily leads to energy waste. Therefore, an improvement is being made to a waste heat recycling and energy-saving system for yak milk production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a waste heat recycling and energy-saving system for yak milk production, which overcomes the deficiencies of existing technologies and aims to solve the problem of energy waste caused by the failure to utilize the waste heat generated during the high-temperature sterilization process in the processing of dairy products.

[0005] To achieve the above objectives, this application provides the following technical solution: a waste heat recycling and energy-saving system for yak milk production, comprising a high-temperature sterilization device, wherein a heater is fixedly installed inside the high-temperature sterilization device, a steam outlet and a feed inlet are fixedly connected to the top of the high-temperature sterilization device, a preheating tank is provided on one side of the high-temperature sterilization device, the interior of the preheating tank is filled with yak milk raw materials, a heating sleeve is fixedly fitted to the outer wall of the preheating tank, and the heating sleeve is connected to the steam outlet through a gas pipe, a conveying unit is fixedly connected to the lower end of the preheating tank, the other end of the conveying unit is connected to the feed inlet, a stirring unit is provided inside the high-temperature sterilization device, and a discharge pipe is fixedly connected to the lower end of the high-temperature sterilization device.

[0006] By adopting the above technical solution, yak milk is sterilized at high temperature using a heater in a high-temperature sterilization device. The yak milk in the high-temperature sterilization device is stirred by a stirring unit to ensure uniform heating. The sterilized yak milk is discharged through a discharge pipe and enters the subsequent processing stage. During this high-temperature sterilization process, steam containing residual heat is generated. This steam is discharged through a steam outlet and guided to the heating jacket through a gas pipe. The high-temperature steam in the heating jacket preheats the yak milk to be processed in the preheating tank through heat conduction, raising the initial temperature of the yak milk. The preheated yak milk is then fed into the high-temperature sterilization device from the inlet through a conveying unit. In other words, this system reduces the demand for additional energy in the preheating stage by using the directly discharged steam waste heat for yak milk preheating, thus achieving energy recycling.

[0007] As a preferred technical solution of this application, the stirring unit includes a drive motor fixedly installed on the top of the high-temperature sterilization device and a stirring shaft disposed inside the high-temperature sterilization device. The upper end of the stirring shaft is fixedly connected to the output end of the drive motor, and a plurality of stirring blades are fixedly connected to the outer wall of the stirring shaft.

[0008] By adopting the above technical solution, the stirring shaft is driven by a drive motor to rotate, thereby driving the stirring blades to stir the yak milk in the high-temperature sterilization device, so that the yak milk can be heated evenly.

[0009] As a preferred technical solution of this application, both the stirring shaft and the stirring blade are stainless steel components, and a gap is left between the outer wall of the stirring blade and the inner wall of the high-temperature sterilization device.

[0010] By adopting the above technical solution, the stirring shaft and stirring blades made of stainless steel meet food safety requirements, ensuring that the stirring blades will not scrape against the inner wall of the high-temperature sterilization device when rotating, thus ensuring safe use.

[0011] As a preferred technical solution of this application, the conveying unit includes a conveying pump, the input end and the output end of the conveying pump are respectively fixedly connected to an inlet pipe and an outlet pipe, the conveying pump is connected to a preheating tank through the inlet pipe, and the conveying pump is connected to a feed inlet through the outlet pipe.

[0012] By adopting the above technical solution, the delivery pump extracts the yak milk to be processed from the preheating tank through the inlet pipe, and delivers the yak milk to the high-temperature sterilization device through the outlet pipe and the inlet for high-temperature sterilization.

[0013] As a preferred technical solution of this application, the heating jacket is hollow, and the inner wall of the heating jacket is fixedly connected with a heat insulation layer, which is made of polyurethane foam.

[0014] By adopting the above technical solution, the hollow structure of the heating jacket provides space for high-temperature steam to be contained and flow, and the heat insulation layer blocks the heat inside the heating jacket from diffusing to the external environment.

[0015] As a preferred technical solution of this application, a drain pipe is fixedly connected to the outer wall of the heating jacket near the bottom, and the drain pipe is equipped with a valve.

[0016] By adopting the above technical solution, after the high-temperature steam enters the heating jacket, it will gradually condense into liquid water during the process of releasing heat to preheat the yak milk, and this liquid water will be discharged through the drain pipe.

[0017] As a preferred technical solution of this application, the top of the preheating tank is fixedly connected to a feeding port, and a sealing cap is threaded onto the outer wall of the feeding port.

[0018] By adopting the above technical solution, the feeding port serves as the inlet for the yak milk to be processed to enter the preheating tank, which makes it convenient for operators to replenish the raw materials into the tank regularly or continuously. The sealed cover prevents heat from overflowing and also blocks external dust, impurities and other contaminants from entering the tank.

[0019] In summary, the beneficial effects of this application are as follows: In this application, yak milk is sterilized at high temperature using a heater in a high-temperature sterilization device. The yak milk in the high-temperature sterilization device is stirred by a stirring unit to ensure uniform heating. The sterilized yak milk is discharged through a discharge pipe and enters the subsequent processing stage. During this high-temperature sterilization process, steam containing residual heat is generated. This steam is discharged through a steam outlet and guided to the heating jacket through a gas pipe. The high-temperature steam in the heating jacket preheats the yak milk to be processed in the preheating tank through heat conduction, raising the initial temperature of the yak milk. The preheated yak milk is then fed into the high-temperature sterilization device from the inlet through a conveying unit. In other words, this system reduces the need for additional energy in the preheating stage by using the waste heat of the directly discharged steam for yak milk preheating, thus achieving energy recycling.

[0023] like Figure 1 - Figure 4 As shown, this embodiment provides a yak milk production waste heat recycling energy-saving system, including a high-temperature sterilization device 1. A heater 4 is fixedly installed inside the high-temperature sterilization device 1. A steam outlet 6 and a feed inlet 8 are fixedly connected to the top of the high-temperature sterilization device 1. A preheating tank 2 is provided on one side of the high-temperature sterilization device 1. The preheating tank 2 is filled with yak milk raw materials. A heating sleeve 3 is fixedly fitted onto the outer wall of the preheating tank 2, and the heating sleeve 3 is connected to the steam outlet 6 through a gas pipe 7. A conveying unit 9 is fixedly connected to the lower end of the preheating tank 2, and the other end of the conveying unit 9 is connected to the feed inlet 8. A stirring unit 5 is provided inside the high-temperature sterilization device 1. The lower end is fixedly connected to the discharge pipe 15. During use, the yak milk is sterilized at high temperature by the heater 4, and the yak milk in the high temperature sterilization device 1 is stirred by the stirring unit 5 to make it heat evenly. The sterilized yak milk is discharged through the discharge pipe 15. During this high temperature sterilization process, steam containing residual heat is generated. This steam is discharged through the steam outlet 6 and guided to the heating jacket 3 through the air pipe 7. The high temperature steam in the heating jacket 3 will preheat the yak milk to be processed in the preheating tank 2 through heat conduction, raising the initial temperature of the yak milk. The preheated yak milk is sent into the high temperature sterilization device 1 from the feed inlet 8 through the conveying unit 9, and the above high temperature sterilization process is repeated.

[0024] In this embodiment, as Figure 2 As shown, the stirring unit 5 includes a drive motor 51 fixedly installed on the top of the high-temperature sterilization device 1 and a stirring shaft 52 disposed inside the high-temperature sterilization device 1. The upper end of the stirring shaft 52 is fixedly connected to the output end of the drive motor 51. Several stirring blades 53 are fixedly connected to the outer wall of the stirring shaft 52. In use, the stirring shaft 52 is driven to rotate by the drive motor 51 to drive the stirring blades 53 to rotate and stir the yak milk in the high-temperature sterilization device 1, so that the yak milk can be heated evenly.

[0025] In this embodiment, as Figure 2As shown, both the stirring shaft 52 and the stirring blade 53 are stainless steel components, and there is a gap between the outer wall of the stirring blade 53 and the inner wall of the high-temperature sterilization device 1. When in use, the stirring shaft 52 and the stirring blade 53, which are made of stainless steel, meet food safety requirements, so that the stirring blade 53 will not scrape against the inner wall of the high-temperature sterilization device 1 when rotating, thus ensuring safe use.

[0026] In this embodiment, as Figure 1 and 3 As shown, the conveying unit 9 includes a conveying pump 92. The input end and output end of the conveying pump 92 are respectively fixedly connected to an inlet pipe 91 and an outlet pipe 93. The conveying pump 92 is connected to the preheating tank 2 through the inlet pipe 91 and to the feed inlet 8 through the outlet pipe 93. In use, the conveying pump 92 draws out the yak milk to be processed from the preheating tank 2 through the inlet pipe 91 and conveys the yak milk to the high-temperature sterilization device 1 through the outlet pipe 93 and the feed inlet 8 for high-temperature sterilization.

[0027] In this embodiment, as Figure 4 As shown, the heating jacket 3 is hollow, and the inner wall of the heating jacket 3 is fixedly connected with a heat insulation layer 12, which is made of polyurethane foam. During use, the hollow structure of the heating jacket 3 provides space for high-temperature steam to be contained and flow, and the heat insulation layer 12 blocks the heat inside the heating jacket 3 from diffusing to the external environment.

[0028] In this embodiment, as Figure 4 As shown, a drain pipe 13 is fixedly connected to the outer wall of the heating jacket 3 near the bottom. The drain pipe 13 is equipped with a valve 14. When in use, after the high-temperature steam enters the heating jacket 3, it will gradually condense into liquid water during the process of releasing heat to preheat the yak milk. This liquid water will be discharged through the drain pipe 13.

[0029] In this embodiment, as Figure 3 As shown, a feeding port 10 is fixedly connected to the top of the preheating tank 2. A sealing cap 11 is threaded onto the outer wall of the feeding port 10. During use, the feeding port 10 serves as the inlet for the yak milk to be processed to enter the preheating tank 2, making it convenient for operators to replenish the raw materials into the tank regularly or continuously. The sealing cap 11 prevents heat from overflowing and also blocks external dust, impurities, etc. from entering the tank.

[0030] The working principle of this application is as follows: When using the waste heat recycling energy-saving system for yak milk production according to this application, yak milk to be processed is first added to the preheating tank 2 through the feeding port 10 at the top. Then, the conveying unit 9 is started to temporarily transport the yak milk to the high-temperature sterilization device 1. When the yak milk in the high-temperature sterilization device 1 reaches a certain amount, the conveying unit 9 is turned off, and the preheating tank 2 is filled with raw materials again to prepare for subsequent circulation. Then, the heater 4 and the drive motor 51 are started. The heater 4 sterilizes the yak milk in the high-temperature sterilization device 1 at high temperature. The stirring shaft 52, driven by the drive motor 51, rotates with the stirring blades 53 to sterilize the yak milk in the high-temperature sterilization device 1. Stirring ensures the yak milk is heated evenly, generating steam containing residual heat. This steam is discharged through steam outlet 6 and guided to heating jacket 3 via air pipe 7. The high-temperature steam in heating jacket 3 preheats the yak milk to be processed in preheating tank 2 through heat conduction, raising the initial temperature of the yak milk in preheating tank 2. After the high-temperature sterilization device 1 completes the high-temperature sterilization process, the yak milk is completely discharged through discharge pipe 15. At this time, the transfer pump 92 is started, and the preheated yak milk in preheating tank 2 is extracted by the transfer pump 92 and liquid inlet pipe 91. Then, the yak milk is transported to high-temperature sterilization device 1 through liquid outlet pipe 93 and feed port 8, repeating the above high-temperature sterilization process.
