Description

Technical Field

[0001] This utility model belongs to the technical field of milk and dairy product production, and specifically relates to a temperature measuring device for a dairy product processing line. Background Technology

[0002] Each dairy farm has a centralized milking parlor. Freshly milked milk is quite hot and needs to be rapidly cooled by a quick-cooling system to reduce bacterial growth and maintain milk quality. The outlet temperature of the quick-cooling system is a crucial indicator of its cooling effectiveness and its impact on raw milk quality. Collecting and evaluating the outlet temperature of the quick-cooling system is an important aspect of quality management.

[0003] Modern dairy production is large-scale industrial production. Each dairy company's supply chain includes hundreds of small and medium-sized farms that supply raw milk. Rapid and non-destructive measurement of the raw milk outlet temperature of the rapid cooling system at each different farm is of great significance for raw milk quality management.

[0004] Currently, various dairy farms use two main methods for temperature measurement: sampling measurement and invasive temperature sensor measurement. Sampling measurement involves manually sampling raw milk to measure its temperature, but the results are easily affected by human factors and lack real-time accuracy. Invasive temperature sensor measurement involves drilling holes or installing flanges in the raw milk pipeline, inserting the temperature sensor probe into the pipeline, and welding the sensor housing to the pipeline. However, this method is destructive and compromises the pipeline's seal. Furthermore, it creates an uneven surface inside the pipeline, leading to milk residue accumulation, cleaning dead zones, bacterial growth, and raw milk contamination. Utility Model Content

[0005] This invention provides a temperature measuring device for a dairy processing line to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A temperature measuring device for a dairy processing line includes an upper shell and a lower shell. The upper shell and the lower shell can be spliced ​​together and fitted onto the outside of a raw milk pipeline. A temperature sensor probe is installed inside the lower shell. An elastic abutment is provided between the temperature sensor probe and the inner wall of the lower shell. After the upper shell and the lower shell are fitted onto the outside of the raw milk pipeline, the elastic abutment pushes the temperature sensor probe against the wall of the raw milk pipeline.

[0008] Furthermore, the surface of the temperature sensor probe is arc-shaped and fits and matches the arc surface of the outer wall of the raw milk pipe;

[0009] The lower housing is installed at the bottom of the raw milk pipeline, and the temperature sensor probe is in contact with the wall of the bottommost area of ​​the raw milk pipeline.

[0010] Furthermore, the elastic clamping element is made of heat-insulating material.

[0011] Furthermore, a flexible abutment layer is provided inside the upper shell. When the upper shell and the upper shell are sleeved on the outside of the raw milk pipe, the flexible abutment layer abuts tightly against the outer wall of the raw milk pipe.

[0012] Furthermore, the flexible contact layer is made of a heat-dissipating material.

[0013] Furthermore, the temperature sensor probe is provided with multiple supporting arc plates around its periphery. These supporting arc plates are fixed at intervals to the surface of the elastic abutment for contact with the raw milk pipe.

[0014] Furthermore, the sidewalls of the upper housing that contact the lower housing are provided with alignment holes, and the sidewalls of the lower housing that contact the upper housing are each provided with a limiting key for insertion into the alignment hole.

[0015] Furthermore, annular mounting grooves are provided on the side wall surfaces where the upper housing and the lower housing contact each other, and sealing rings are fixed in the annular mounting grooves.

[0016] The present invention can achieve the following beneficial effects:

[0017] 1. By installing the temperature measuring device of this application on the outer sleeve of the raw milk pipeline, the temperature of the milk flowing out of the raw milk pipeline can be measured in real time by the temperature measuring device of this application; the temperature measuring device of this application is simple to install and disassemble and easy to operate; in addition, the temperature measuring device of this application does not come into contact with the raw milk, does not affect the quality of the raw milk being tested, and has a low manufacturing cost.

[0018] 2. An elastic abutment with heat insulation function is installed in the lower shell. Regardless of the milk flow rate in the raw milk pipeline, the milk will definitely pass through the bottom wall area of ​​the raw milk pipeline. The elastic abutment in the lower shell can reduce heat loss, so that the milk temperature can be accurately transmitted to the temperature sensor probe for temperature measurement. A flexible abutment layer with heat dissipation function is installed in the upper shell, so that heat can be slowly dissipated, thereby reducing the impact of heat accumulation inside the upper and lower shells on the accuracy of subsequent milk temperature measurement.

[0019] 3. Through the elastic action of the elastic abutment and flexible abutment layer, the upper and lower shells can be stably pressed against the outside of the raw milk pipeline, thereby allowing the temperature sensor probe to fit more closely with the raw milk pipeline and achieve higher temperature measurement accuracy.

[0026] 100. Raw milk pipeline. Detailed Implementation

[0027] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0028] like Figures 1 to 3 As shown, a temperature measuring device for a dairy processing line includes an upper housing 1 and a lower housing 2. During installation, the upper housing 1 and the lower housing 2 are fastened to the outside of the raw milk pipeline 100, and the upper housing 1 and the lower housing 2 are fastened together by screws and nuts. By adjusting the screws and nuts, the temperature measuring device of this application is tightly wrapped around the outside of the raw milk pipeline 100.

[0029] Specifically, a temperature sensor probe 3 is installed inside the lower housing 2. The surface of the temperature sensor probe 3 is arc-shaped and fits snugly against the arc surface of the outer wall of the raw milk pipe 100, thereby measuring the temperature of the milk inside the raw milk pipe 100. In actual installation, the lower housing 2 is first installed at the bottom of the raw milk pipe 100. Since the milk must first contact the bottom area of ​​the raw milk pipe 100 regardless of the flow rate, installing the lower housing 2 at the bottom of the raw milk pipe 100 and contacting the temperature sensor probe 3 with the bottommost area of ​​the raw milk pipe 100 can reduce the instability of temperature measurement caused by changes in milk flow rate.

[0030] In addition, during installation, it is necessary to ensure that the temperature sensor probe 3 can fit tightly against the wall of the bottom area of ​​the raw milk pipe 100, thereby improving the temperature measurement accuracy. Therefore, an elastic clamping member 4 is provided between the temperature sensor probe 3 and the inner wall of the lower housing 2. After the upper housing 1 and the lower housing 2 are assembled and fitted onto the outside of the raw milk pipe 100, the elastic clamping member 4 can provide a pushing force to move the temperature sensor probe 3 toward the raw milk pipe 100 and clamp it.

[0031] Meanwhile, the elastic clamping part 4 is made of heat-insulating material. When milk flows out through the raw milk pipe 100, the heat-insulating elastic clamping part 4 can block heat from being dissipated from the raw milk pipe 100, thereby further ensuring that the temperature of the milk is accurately transmitted to the temperature sensor probe 3 and achieving accurate measurement. On the other hand, the elasticity of the elastic clamping part 4 enhances the adhesion stability between the temperature sensor probe 3 and the wall of the raw milk pipe 100.

[0032] The raw milk pipe 100 can specifically be a stainless steel pipe. It should be noted that during measurement, when raw milk flows through the raw milk pipe 100, the temperature of the outer wall of the raw milk pipe 100 will change with the temperature of the milk. When the milk temperature is transmitted to the outer wall of the raw milk pipe 100, there will be a temperature loss K. The temperature loss value K varies depending on the material and thickness of the raw milk pipe 100. The raw milk temperature measured by the temperature sensor probe 3 = the outer wall temperature of the raw milk stainless steel pipe - K.

[0033] A flexible abutment layer 5 is provided inside the upper housing 1. When the upper and lower housings 2 are fitted onto the outside of the raw milk pipe 100, the flexible abutment layer 5 will abut against the outer wall of the raw milk pipe 100. After the measuring device of this application is installed, the flexible abutment layer 5 works in conjunction with the elastic clamping member 4 to make the upper housing 1 and the lower housing 2 more securely wrapped around the raw milk pipe 100, which can play a role in stabilizing the measuring device.

[0034] The flexible contact layer 5 is made of heat dissipation material. As the measurement is carried out, a certain amount of heat will accumulate inside the measuring device due to the heat transfer of the milk. The flexible contact layer 5 can slowly dissipate this heat to avoid excessive heat accumulation inside, which would affect the accuracy of subsequent milk temperature measurements and ensure the accuracy of the measurement results.

[0035] Multiple abutment plates 6 are arranged around the temperature sensor probe 3, and these plates are fixed at intervals to the surface of the elastic retainer 4. During the installation and use of the measuring device, the abutment plates 6 can abut against the raw milk pipeline 100. When the measuring device is affected by external vibrations or other factors, the abutment plates 6 can increase the contact stability between the temperature sensor probe 3 and the raw milk pipeline 100, prevent the probe from loosening, and thus further ensure the accuracy of temperature measurement and the reliability of measurement data.

[0036] The sidewalls of the upper housing 1 and the lower housing 2 that contact each other are provided with alignment holes 11. The sidewalls of the lower housing 2 that contact the upper housing 1 are provided with limiting keys 21 for insertion into the alignment holes 11. The limiting keys 21 and the alignment holes 11 are arranged in a one-to-one correspondence. When assembling the upper and lower housings 2, multiple limiting keys 21 are inserted into multiple alignment holes 11 one-to-one, which can quickly and accurately complete the assembly operation, effectively ensuring that there is no misalignment between the upper housing 1 and the lower housing 2, greatly improving the installation efficiency of the device and saving installation time and labor costs.

[0037] Annular mounting grooves 12 are provided on the sidewall surfaces where the upper housing 1 and the lower housing 2 meet, and sealing rings are fixed inside the annular mounting grooves 12. After the upper housing 1 and the lower housing 2 are assembled, the sealing rings will fill the gap between the upper housing 1 and the lower housing 2. The sealing rings prevent external water from entering the measuring device, reducing the damage or impact of water on internal components such as the temperature sensor probe 3, thereby ensuring the long-term stable operation of the measuring device, extending its service life, and also ensuring the accuracy of the measured temperature.

[0038] In summary, this utility model's rapid cooling outlet temperature measuring device, through the synergy of its various technical features, achieves advantages such as accurate milk temperature measurement, convenient installation and disassembly, high stability, and low cost. It effectively solves the problems existing in current measurement methods, providing a reliable and practical solution for temperature measurement in the dairy production industry. Furthermore, since dairy farms are scattered across rural areas nationwide, far from major cities, the measuring device of this application is simple to install, requires minimal maintenance, and is easy to deploy and operate long-term.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
