Description

Technical Field

[0001] This application relates to the field of dairy production technology, specifically to a temperature control device for milk entering the storage silo. Background Technology

[0002] Milk silos are containers used to store dairy products. They are typically large in volume and can hold a significant amount. To extend the shelf life of dairy products, the temperature inside the silo is usually low. If newly processed dairy products are directly introduced into the silo, the temperature of the existing milk will rise due to heat exchange, altering the overall temperature within the silo. This temperature will no longer be suitable for long-term storage. Therefore, current technologies require temperature pretreatment using temperature control equipment before introducing new milk into the silo to ensure the temperature of the new milk matches that of the existing milk. However, existing temperature control equipment is limited in function, simply cooling the milk before conveying it to the silo, resulting in inconsistent cooling performance. Utility Model Content

[0003] In view of the above problems, this application provides a temperature control device for milk products before they enter the milk storage chamber, which can efficiently control the temperature of milk products before they enter the milk storage chamber, and the temperature fluctuation of the milk products entering the milk storage chamber is small.

[0004] According to one aspect of the embodiments of this application, a temperature control device for milk storage before milk is put into storage is provided. The temperature control equipment before milk enters the milk silo includes a storage tank, a buffer tank, and a heat exchange box. The buffer tank is located on one side of the storage tank, and the heat exchange box is located on one side of the storage tank. The storage tank has a raw material inlet, and a first conveying pipe is located at the bottom of the storage tank. A first discharge valve is located at the first conveying pipe. The buffer tank is arranged horizontally, and a stirring device is arranged horizontally inside the buffer tank. A first three-way valve is located at the top of the buffer tank. A second conveying pipe is located between the first discharge valve and the first three-way valve. A second discharge valve is located at the bottom of the buffer tank. The second discharge valve is connected to a third conveying pipe, which is connected to the inlet end of the heat exchange box. The outlet end of the heat exchange box is connected to a temperature measuring box, which is electrically connected to a PLC controller. An electromagnetic three-way valve is connected to the side of the temperature measuring box away from the heat exchange box. The electromagnetic three-way valve is electrically connected to the PLC controller. The electromagnetic three-way valve is connected to the first three-way valve and the milk silo through a fourth conveying pipe and a fifth conveying pipe, respectively.

[0005] In some embodiments, the stirring device includes a stirring shaft arranged laterally inside the buffer tank, one end of which extends to the outer periphery of the buffer tank and is connected to a stirring motor.

[0006] In some embodiments, one side of the buffer tank is connected to a material inlet via a pipe.

[0007] In some embodiments, the storage tank includes a tank body and a support frame. The support frame is sleeved around the outer periphery of the tank body and supports the bottom of the tank body. The bottom of the tank body tapers inward to form a conical discharge end, and the first conveying pipe is connected to the bottom of the discharge end.

[0008] In some embodiments, a plurality of heat dissipation fins are connected to the outer periphery of the tank body, and the plurality of heat dissipation fins penetrate and extend to the outside of the support frame.

[0009] In some embodiments, the heat exchange box is provided with a heat exchange coil inside, and the two ends of the heat exchange coil are respectively connected to the inlet end and the outlet end of the heat exchange box. A cooler is connected to one side of the heat exchange box through a medium circulation pipe.

[0010] The beneficial effects of this application are as follows: In this application, by setting up a storage tank, a buffer tank, and a heat exchange box, a large quantity of milk is stored in the storage tank. Milk is supplied sequentially from the storage tank to the buffer tank. The milk then circulates between the buffer tank and the heat exchange box. Once the milk reaches the required temperature, it is sent to the milk hopper for storage. The amount of milk circulating for cooling is relatively small compared to the total mass of milk in the storage tank, enabling rapid cooling without causing rapid temperature fluctuations in the large quantity of milk in the storage tank. This application, through the coordinated use of components such as a temperature measuring box and a PLC controller, allows the PLC to automatically control a solenoid three-way valve after cooling, thereby sending the milk into the milk hopper. When the milk temperature has not dropped to the preset threshold, the PLC automatically controls the solenoid three-way valve to send the milk into the buffer tank for further cooling.

Figure 4This is a schematic cross-sectional view of the buffer tank provided in an embodiment of this application. The temperature control device 100 before milk enters the silo includes a storage tank 110, a buffer tank 120, and a heat exchange box 130. The storage tank 110 typically has a large volume to accommodate all freshly produced milk at once. Its specific dimensions can be set according to the actual production volume. There can be multiple storage tanks 110, which can be connected in series. The buffer tank 120 is relatively small. The heat exchange box 130 is used to circulate and cool the milk in the buffer tank 120. A buffer tank 120 is located on one side of the storage tank 110, and a heat exchange box 130 is located on one side of the storage tank 110. The storage tank 110 has a raw material inlet 111, and a first conveying pipe 112 is located at the bottom of the storage tank 110. A first discharge valve 113 is located at the first conveying pipe 112. The buffer tank 120 is arranged horizontally, and a stirring device 121 is arranged horizontally inside the buffer tank 120. The stirring device 121 is used to stir the milk inside the buffer tank 120 so that its temperature tends to be uniform after rapid heat exchange. A first three-way valve 122 is located at the top of the buffer tank 120. A second conveying pipe 123 is arranged between the first discharge valve 113 and the first three-way valve 122. The milk inside the storage tank 110 can enter the buffer tank 120 through the first conveying pipe 112 and the second conveying pipe 123. A pump body can be installed at the first conveying pipe 112 to pump the milk into the buffer tank 120. The first discharge valve 113 opens intermittently, allowing a sufficient amount of milk to pass through before closing. It remains open until the milk in the buffer tank 120 has cooled completely and entered the milk hopper, at which point it reopens to transfer milk from the storage tank 110 into the buffer tank 120. A second discharge valve 124 is located at the bottom of the buffer tank 120, connected to a third conveying pipe 125. This third conveying pipe 125 connects to the inlet of the heat exchanger 130. Milk from the buffer tank 120 is fed into the heat exchanger 130 via the third conveying pipe 125, and after cooling, it flows through the fourth conveying pipe 142 and the first three-way valve 122 into the buffer tank 120. A temperature measuring box 140 is connected to the outlet of the heat exchanger 130 to detect the temperature of the milk at the outlet of the heat exchanger 130. The temperature measuring box 140 is electrically connected to a PLC controller. A solenoid three-way valve 141 is connected to the side of the temperature measuring box 140 away from the heat exchange box 130. The solenoid three-way valve 141 is electrically connected to the PLC controller. The solenoid three-way valve 141 is connected to the first three-way valve 122 and the hopper via the fourth feed pipe 142 and the fifth feed pipe 145, respectively. A temperature threshold is preset. When the temperature of the milk is lower than the preset threshold, the PLC control box controls the temperature measuring box 140 to connect with the fifth feed pipe 145, at which point the milk will be sent into the milk hopper. When the temperature of the milk detected in the temperature measuring box 140 is higher than the preset threshold, the PLC control box controls the temperature measuring box 140 to connect with the fourth feed pipe 142, at which point the milk will be sent into the buffer tank 120. After heat exchange with the milk in the buffer tank 120, the milk will re-enter the heat exchange box 130 for cooling until its temperature reaches the target level before being sent into the milk hopper.

[0021] As can be seen from the above, in this embodiment, by setting up a storage tank 110, a buffer tank 120, and a heat exchange box 130, a large quantity of milk is stored in the storage tank 110. Milk is supplied sequentially from the storage tank 110 to the buffer tank 120. Subsequently, the milk circulates between the buffer tank 120 and the heat exchange box 130. After the milk temperature reaches the required value, it is sent to the milk hopper for storage. Thus, the amount of milk circulating for cooling is relatively small compared to the total mass of milk inside the storage tank 110, which can quickly complete the cooling process without causing rapid temperature fluctuations in the large quantity of milk in the storage tank 110. This application sets up a temperature measuring box 140, a PLC controller, and other components to work together so that after the milk has been cooled, the PLC can automatically control the electromagnetic three-way valve 141 to send the milk into the milk hopper. When the milk temperature has not dropped to the preset threshold, the PLC automatically controls the electromagnetic three-way valve 141 to send the milk into the buffer tank 120 for further cooling.

[0022] In some embodiments, the stirring device 121 includes a stirring shaft arranged laterally within the buffer tank 120, with one end extending to the outer periphery of the buffer tank 120 and connected to a stirring motor. In this embodiment, the stirring device 121 can be configured using existing technology. The stirring device 121 drives the stirring shaft to rotate via the stirring motor, allowing the milk that has undergone heat exchange in the heat exchange box 130 to enter the buffer tank 120 and quickly mix with the high-temperature milk inside the buffer tank 120 to complete heat exchange. This results in a uniform temperature of the milk inside the buffer tank 120 and further reduces temperature fluctuations of the milk at the heat exchange box 130.

[0023] In some embodiments, a receiving port 126 is connected to one side of the buffer tank 120 via a pipe. In this embodiment, by providing the receiving port 126, when producing a small amount of milk at a time, the corresponding pipe can be connected to the receiving port 126 and the milk can be directly fed into the buffer tank 120 through the receiving port 126, without needing to enter the storage tank 110, thus saving operation steps.

[0024] In some embodiments, the storage tank 110 includes a tank body 116 and a support frame 114. The support frame 114 is sleeved around the outer periphery of the tank body 116 and supports the bottom of the tank body 116. The bottom of the tank body 116 tapers inward to form a conical discharge end, and a first conveying pipe 112 is connected to the bottom of the discharge end. In this embodiment, the above arrangement makes the bottom of the tank body 116 conical, thereby allowing the milk inside the storage tank 110 to flow out completely.

[0025] In some embodiments, a plurality of heat dissipation fins 115 are connected to the outer periphery of the tank body 116, and the plurality of heat dissipation fins 115 penetrate and extend to the outer side of the support frame 114. In this embodiment, through the above arrangement, the milk inside the tank body 116 can be pre-cooled by the heat dissipation fins 115, thereby accelerating the heat dissipation effect and reducing the heat dissipation time when the milk enters the buffer tank 120 later.

[0026] In some embodiments, a heat exchange coil is provided inside the heat exchange box 130, with its two ends connected to the inlet and outlet ends of the heat exchange box 130, respectively. A cooler is connected to one side of the heat exchange box 130 via a medium circulation pipe. In this embodiment, through the above arrangement, the cooler lowers the temperature of the circulating medium, which then exchanges heat with the milk in the heat exchange coil inside the heat exchange box 130, thereby reducing the temperature of the milk.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
