Description

Technical Field

[0001] This invention belongs to the field of yogurt fermentation technology, specifically relating to a yogurt fermentation chamber and its temperature control system. Background Technology

[0002] A yogurt fermentation chamber is a specialized facility used for yogurt fermentation. It is typically a sealed room or area with controlled temperature and humidity, used to house the main fermentation chamber or fermentation equipment. Within the yogurt fermentation chamber, temperature and humidity need to be precisely controlled to ensure successful fermentation. Simultaneously, the chamber must be kept clean and hygienic to prevent contamination and bacterial growth.

[0003] A yogurt fermentation chamber is a specialized facility used for yogurt fermentation. It is typically a sealed room or area with controlled temperature and humidity, housing the main fermentation unit or fermentation equipment. Within the yogurt fermentation chamber, temperature and humidity need to be precisely controlled to ensure successful fermentation. Simultaneously, the chamber must be kept clean and hygienic to prevent contamination and bacterial growth. Specialized equipment is usually installed in the yogurt fermentation chamber to monitor and control parameters such as temperature and humidity to ensure the quality and safety of the fermented yogurt. Furthermore, the fermentation chamber needs to be cleaned and disinfected regularly to maintain the cleanliness and hygiene of the equipment.

[0004] The temperature control system for yogurt is crucial for ensuring a stable fermentation process, product quality, and taste. This system typically includes temperature sensors, control circuitry, and heating or cooling equipment. The temperature sensors monitor the temperature within the fermentation chamber and transmit signals to the control circuitry. Based on the set temperature range and the sensor feedback, the control circuitry manages the operation of the heating or cooling equipment to maintain a stable temperature within the fermentation chamber. During yogurt fermentation, the temperature control system needs to precisely control the temperature to ensure effective lactic acid bacteria fermentation and a pleasant yogurt taste. Excessively high or low temperatures can negatively impact the growth of lactic acid bacteria and the fermentation process, leading to a decline in yogurt quality. Therefore, the temperature control system is a critical piece of equipment in yogurt production and requires regular maintenance and calibration to ensure its proper functioning and accuracy. Furthermore, it needs to be optimized and improved based on actual production needs and equipment performance to enhance production efficiency and product quality.

[0005] In the yogurt production process, when the yogurt is fermenting in the yogurt fermentation chamber, a temperature control system is used to control the ambient temperature of the yogurt during the yogurt production process. When the main body of the fermentation chamber is inside, the temperature inside and outside the fermentation chamber is monitored in real time by the temperature control system to provide constant temperature support for yogurt fermentation. However, the temperature detection equipment installed in the main body of the fermentation chamber is limited by the lack of spatial adjustment function, which makes it impossible to monitor the temperature of the yogurt in different spatial locations within the fermentation chamber. It is also impossible to accurately monitor the temperature of local locations during the yogurt fermentation process in a timely manner, resulting in temperature differences between local locations and other locations in the chamber. This leads to local temperature anomalies within the fermentation chamber, causing a decrease in the quality of the yogurt after fermentation. Therefore, we propose a yogurt fermentation chamber and its temperature control system. Summary of the Invention

[0006] The purpose of this invention is to provide a yogurt fermentation chamber and its temperature control system, which aims to solve the problem that the temperature detection equipment installed in the main body of the fermentation chamber does not have the function of spatial adjustment, making it impossible to monitor the temperature of the yogurt in different spatial locations within the fermentation chamber. This makes it impossible to accurately monitor the temperature of local locations during the yogurt fermentation process in a timely manner, resulting in temperature differences between local locations and other locations within the chamber, causing abnormal local temperatures within the fermentation chamber and a reduction in the quality of the yogurt after fermentation.

[0020] In a preferred embodiment of the present invention, a sealing ring is fitted on the circumferential surface of the support rod, and the sealing ring is fixedly connected to the bottom of the rotating sleeve;

[0021] A terminal is fixedly connected to the top of the main body of the fermentation chamber.

[0022] A fermentation cellar, comprising:

[0023] The main body of the fermentation chamber, and the temperature control system is located on the main body of the fermentation chamber.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this solution, when it is necessary to collect the temperature of the yogurt inside the fermentation chamber in a dispersed manner, the support rod and the electric telescopic rod are on the same vertical axis. The terminal first powers on and starts the lifting motor. The output end of the lifting motor drives the lead screw to rotate. The lead screw drives the slider to rise and fall through the sliding engagement with the slider. The slider drives the lifting rod to rise and fall, so that the lifting rod drives the lifting block to rise and fall within the rotating sleeve. Under the sliding engagement of multiple guide blocks and guide grooves, the lifting block drives the support rod to retract and move at the bottom of the rotating sleeve, pushing the support rod out of the rotating sleeve. The support rod pushes the support block to move. The support block pushes the electric telescopic rod to fall through the sliding engagement with the rotating block, and then inserts the electric telescopic rod into the yogurt. The terminal then powers on and starts the drive motor. The output end of the drive motor drives the drive gear to rotate. The drive gear drives the driven gear to rotate through the meshing with the driven gear. The driven gear drives the rotating sleeve to rotate. The rotating sleeve drives the lifting block to rotate through the sliding engagement of multiple rotating sleeves and guide grooves. The lifting block drives the lifting block to rotate. The moving support rod rotates, causing the support block to rotate. The support block, in conjunction with the rotating block, drives the rotating block to rotate, causing the temperature sensor at the top of the electric telescopic rod to move horizontally within the yogurt container. The terminal is then powered on again to activate the second electric push rod. The output end of the second electric push rod pushes and pulls the moving block, raising and lowering it. The moving block pushes and pulls the L-shaped push-pull block, which in turn moves the swing block. The swing block moves the swing sleeve, which uses the axis between the groove and the rotating block as its rotational support point, facilitating the swinging of the electric telescopic rod. This allows the temperature sensor to perform three-dimensional temperature monitoring of the yogurt fermentation process. The temperature detection equipment can monitor the temperature of the yogurt at different spatial locations within the fermentation chamber, enabling timely and accurate temperature monitoring of localized areas during fermentation. This prevents temperature discrepancies between undetected localized areas and other parts of the container, thus preventing abnormal localized temperatures within the fermentation chamber and improving the quality of the fermented yogurt.

[0026] 2. In this scheme, when the temperature sensor needs to be rotated, the drive motor is started. The output of the drive motor drives the driving gear to rotate. The driving gear, through meshing with the driven gear, drives the driven gear to rotate. The driven gear drives the rotating sleeve to rotate. The first rotating groove drives the lifting block to rotate through the engagement between multiple guide blocks and multiple guide grooves. The support rod drives the electric telescopic rod to rotate through the transfer mechanism, so that the temperature sensor rotates within the fermentation chamber body. When the temperature sensor needs to be lifted or moved, the lifting motor is started. The output of the lifting motor drives the lead screw to rotate. The lead screw, through sliding engagement with the slider, pushes the slider forward. The slider moves up and down, driving the lifting rod to move up and down. This, in turn, causes the lifting rod to move up and down the lifting block, which in turn moves the support rod up and down. This allows the support rod to extend and retract within the rotating sleeve, controlling the depth of the temperature sensor within the yogurt. This facilitates the temperature sensor's monitoring of fermentation temperatures at different depths within the yogurt, enabling thorough temperature data collection during fermentation. Furthermore, it increases the ability to collect fermentation temperatures at different locations within the yogurt, allowing the temperature sensor to be immersed at different points on the same horizontal plane within the yogurt. This facilitates multi-point temperature data collection, improving the accuracy of temperature data acquisition during the yogurt fermentation process.

[0027] 3. In this solution, when the temperature sensor needs to be rotated, the output end of the first electric push rod pushes the pawl to engage with the ratchet, thereby locking the rotation of the rotating sleeve. After the rotating sleeve is locked, the support rod cannot drive the temperature sensor to rotate, thus locking and positioning the temperature sensor. After the temperature sensor completes local temperature monitoring, the first electric push rod extends and retracts to pull the pawl away from the ratchet, releasing the engagement and locking between the pawl and the ratchet. By moving the pawl, the rotation and movement of the temperature sensor are controlled, thus accurately positioning the temperature sensor at the temperature acquisition point inside the yogurt.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] Reference Figure 1 - Figure 16 A yogurt fermentation chamber, which consists of a fermentation chamber body 1 equipped with a temperature control system;

[0049] A temperature control system for a yogurt fermentation chamber, comprising:

[0050] The first rotating groove 2 is located on the top of the fermentation chamber body 1;

[0051] Support rod 9 is installed between the inner walls of the main body 1 of the fermentation chamber;

[0052] An electric telescopic rod 13 is installed between the inner walls of the fermentation chamber body 1, and is connected to the support rod 9 via a connecting mechanism. A temperature sensor 14 is fixedly connected to the output end of the electric telescopic rod 13.

[0053] An adjustment mechanism is installed between the inner walls of the fermentation chamber body 1. The adjustment mechanism is connected to the temperature sensor 14 and is used to move the temperature sensor 14.

[0054] In this invention, the fermentation chamber body 1 is used to house the temperature sensor 14, the support rod 9, the transfer mechanism, and the adjustment mechanism. The first rotating groove 2 is opened to house the guide assembly. The support rod 9 supports the rotating block 12 through the transfer mechanism. The electric telescopic rod 13 moves the temperature sensor 14 through the extension and retraction of its output end. The transfer mechanism is used to connect the support rod 9 and the rotating block 12. The adjustment mechanism is connected to the temperature sensor 14 to move the temperature sensor 14.

[0055] The adjustment mechanism includes a guide assembly, a connecting rod assembly, a drive assembly, a limiting assembly, and a lifting assembly. The guide assembly is disposed between the inner walls of the first rotating groove 2 and is connected to the support rod 9. The connecting rod assembly is disposed on the circumferential surface of the support rod 9 and is connected to the electric telescopic rod 13. The drive assembly is disposed on the top of the fermentation chamber body 1 and is connected to the guide assembly. The limiting assembly is disposed on the top of the drive assembly and is connected to the guide assembly. The lifting assembly is disposed on the top of the fermentation chamber body 1 and is connected to the guide assembly.

[0056] In this invention, the guide assembly is used to guide and limit the lifting and rotation of the support rod 9, the linkage assembly is used to swing the temperature sensor 14 significantly, the drive assembly is used to rotate the support rod 9, thereby driving the temperature sensor 14 to rotate within the fermentation chamber body 1, the limiting assembly is used to lock the rotation of the support rod 9, thereby controlling the rotation of the temperature sensor 14, and the lifting assembly is used to adjust the height of the support rod 9, thereby achieving height adjustment of the temperature sensor 14.

[0057] The guiding assembly includes a rotating sleeve 3, guide blocks 4, lifting blocks 5, guide grooves 6, and lifting rods 7. The rotating sleeve 3 is rotatably connected between the inner circumference of the first rotating groove 2 and wraps around the circumference of the support rod 9. Multiple guide blocks 4 are provided and are fixedly connected between the inner walls of the rotating sleeve 3. The lifting blocks 5 slide between the inner walls of the rotating sleeve 3 and are connected to the support rod 9. Multiple guide grooves 6 are provided and are opened on the circumference of the lifting blocks 5. Each guide groove 6 corresponds to a multiple guide blocks 4. The lifting rod 7 is inserted between the inner walls of the rotating sleeve 3 and is connected to the lifting blocks 5.

[0058] In this invention, the rotating sleeve 3 is used to accommodate the lifting block 5 and multiple guide blocks 4. The multiple guide blocks 4 guide the lifting block 5 by slidingly engaging with multiple guide grooves 6. The lifting block 5 drives the support rod 9 to rise and fall. The multiple guide grooves 6 accommodate the multiple guide blocks 4. The lifting rod 7 pushes and pulls the lifting block 5 to rise and fall. When the temperature sensor 14 is raised and lowered, the lifting assembly drives the lifting rod 7 to rise and fall. The lifting rod 7 drives the lifting block 5 to rise and fall. During the raising and lowering process of the lifting block 5, the multiple guide grooves 6 guide the raising and lowering of the lifting block 5 by slidingly engaging with the multiple guide blocks 4. The lifting block 5 drives the support rod 9 to rise and fall. The support rod 9 drives the electric telescopic rod 13 to rise and fall through the transfer mechanism, thereby realizing the raising and lowering of the temperature sensor 14. During the raising and lowering process of the temperature sensor 14, the multiple guide grooves 6 slide with the multiple guide blocks 4, so that the temperature sensor 14 only moves up and down during the raising and lowering process, without generating rotation around the support rod 9 as the axis, so that the temperature sensor 14 rises and falls smoothly and reduces the interference of vibration on the temperature sensor 14 in collecting temperature.

[0059] The drive assembly includes a gear cover 23, a drive motor 24, a driven gear 25, and a driving gear 26. The gear cover 23 is sleeved on the circumferential surface of the lifting rod 7 and the rotating sleeve 3, and the gear cover 23 is fixedly connected to the top of the fermentation chamber body 1. The driven gear 25 is fixedly connected to the circumferential surface of the rotating sleeve 3, and the driven gear 25 is located between the inner walls of the gear cover 23. The driving gear 26 is located between the inner walls of the gear cover 23, and the driving gear 26 meshes with the driven gear 25. The drive motor 24 is fixedly connected to the top of the gear cover 23, and the output end of the drive motor 24 extends to the inner walls of the gear cover 23, and the output end of the drive motor 24 is fixedly connected to the driving gear 26.

[0060] In this invention, the gear cover 23 is used to accommodate the driven gear 25 and the driving gear 26. The driven gear 25 drives the rotating sleeve 3 to rotate. The driving gear 26 drives the driven gear 25 to rotate through meshing with it. The drive motor 24 drives the driving gear 26 to rotate. When it is necessary to rotate the temperature sensor 14, the drive motor 24 is started. The output end of the drive motor 24 drives the driving gear 26 to rotate. The driving gear 26 drives the driven gear 25 to rotate through meshing with it. The driven gear 25 drives the rotating sleeve 3 to rotate. The first rotating groove 2 drives the lifting block 5 to rotate through the engagement between multiple guide blocks 4 and multiple guide grooves 6. The support rod 9 drives the electric telescopic rod 13 to rotate through the transfer mechanism, so that the temperature sensor 14 rotates inside the fermentation chamber body 1. This allows the temperature sensor 14 to be immersed in different positions on the same horizontal plane in the yogurt, facilitating multi-point temperature collection in the fermented yogurt. Multi-point temperature collection improves the accuracy of temperature data collection during the yogurt fermentation process.

[0061] The limiting assembly includes a limiting cover 27, a ratchet 28, a pawl 29, a swing groove 30, and a first electric push rod 31. The limiting cover 27 is fixedly connected to the top of the gear cover 23. The ratchet 28 is fixedly connected to the circumferential surface of the rotating sleeve 3. The pawl 29 is rotatably connected to the top of the gear cover 23 and engages with the ratchet 28. The limiting cover 27 is sleeved on the circumferential surface of the ratchet 28, the pawl 29, the lifting rod 7, and the rotating sleeve 3. The swing groove 30 is opened on the top of the limiting cover 27. The first electric push rod 31 is fixedly connected to the top of the limiting cover 27. The output end of the first electric push rod 31 slides between the inner walls of the swing groove 30 and is rotatably connected to the pawl 29.

[0062] In this invention, the limiting cover 27 is used to accommodate the ratchet 28 and the pawl 29, and the limiting cover 27 provides sealed protection for the ratchet 28 and the pawl 29. The opening of the swing groove 30 is used to accommodate the sliding of the first electric push rod 31. The first electric push rod 31 is used to push and pull the pawl 29 to deflect it. When the rotating sleeve 3 rotates, the rotating sleeve 3 drives the ratchet 28 to rotate. When it is necessary to rotate the temperature sensor 14, the output end of the first electric push rod 31 pushes the pawl 29 to engage with the ratchet 28, thereby realizing the rotation of the rotating sleeve. The rotation of sleeve 3 locks the temperature sensor 14. After the rotation of sleeve 3 is locked, the support rod 9 cannot drive the temperature sensor 14 to rotate, thus locking and positioning the temperature sensor 14. After the temperature sensor 14 completes local temperature monitoring, the first electric push rod 31 extends and retracts to pull the pawl 29 away from the ratchet 28, releasing the engagement and locking between the pawl 29 and the ratchet 28. By moving the pawl 29, the rotation and movement of the temperature sensor 14 are controlled, thus accurately positioning the temperature sensor 14 at the temperature collection point inside the yogurt.

[0063] The lifting assembly includes an adapter 8, a support frame 16, a limiting groove 17, a lifting motor 18, a lead screw 19, a slider 20, a limiting block 21, and a second rotating groove 22. The support frame 16 is fixedly connected to the top of the fermentation chamber body 1. Two limiting grooves 17 are provided, and the two limiting grooves 17 are opened at the side ends of the support frame 16. The lead screw 19 is rotatably connected between the inner walls of the support frame 16. The lifting motor 18 is fixedly connected to the top of the support frame 16, and the output end of the lifting motor 18 is fixedly connected to the lead screw 19. The slider 20 is sleeved on the circumferential surface of the lead screw 19 and the lifting rod 7. Two limiting blocks 21 are provided, and the two limiting blocks 21 slide between the inner walls of the two limiting grooves 17. Both limiting blocks 21 are connected to the slider 20. The second rotating groove 22 is opened at the top of the slider 20. The adapter 8 is rotatably connected between the inner circumferential walls of the second rotating groove 22, and the adapter 8 is connected to the lifting rod 7.

[0064] In this invention, the support frame 16 is used to accommodate the lead screw 19 and the slider 20. The two limiting grooves 17 are used to accommodate the sliding of the two limiting blocks 21. The lead screw 19 pushes the slider 20 to move up and down through sliding cooperation with the slider 20. The slider 20 drives the lifting rod 7 to move up and down. The two limiting blocks 21 guide and limit the movement of the slider 20 through sliding cooperation with the two limiting grooves 17. The second rotating groove 22 is used to accommodate the adapter 8. The adapter 8 is installed to facilitate the internal and external connection of the wires in the wire trough 11. When it is necessary to move the temperature sensor 14 up and down, the lifting motor 18 is started by powering on. The output of the lifting motor 18 drives the lead screw 19 to rotate. The lead screw 19 pushes the slider 20 to move up and down through sliding cooperation with the slider 20. The slider 20 drives the lifting rod 7 to move up and down, which in turn causes the lifting rod 7 to move up and down the lifting block 5. The lifting block 5 drives the support rod 9 to move up and down, realizing the extension and retraction of the support rod 9 within the rotating sleeve 3. This achieves the control of the depth adjustment of the temperature sensor 14 in the yogurt, making it convenient for the temperature sensor 14 to monitor the fermentation temperature at different depths in the yogurt. This facilitates sufficient temperature collection during yogurt fermentation and further increases the collection of fermentation temperature at different locations in the yogurt.

[0065] The linkage assembly includes a mounting block 32, a second electric push rod 33, a moving block 34, an L-shaped push-pull block 35, a swing sleeve 36, and a swing block 37. The mounting block 32 is fixedly connected to the circumferential surface of the support rod 9. The swing sleeve 36 is fitted onto the circumferential surface of the electric telescopic rod 13. The swing block 37 is fixedly connected to the circumferential surface of the swing sleeve 36. The second electric push rod 33 is fixedly connected to the top of the mounting block 32, and the output end of the second electric push rod 33 extends to the bottom of the mounting block 32. The moving block 34 is fixedly connected to the output end of the second electric push rod 33. The L-shaped push-pull block 35 is disposed between the moving block 34 and the swing block 37. One end of the L-shaped push-pull block 35 is rotatably connected to the moving block 34 via a hinge, and the other end of the L-shaped push-pull block 35 is rotatably connected to the swing block 37 via a hinge.

[0066] In this invention, the mounting block 32 supports and fixes the second electric push rod 33. The swing sleeve 36 moves to drive the electric telescopic rod 13 to swing. The swing block 37 drives the swing sleeve 36 to move. The second electric push rod 33 moves the moving block 34 through the extension and retraction of its output end. The moving block 34 moves the L-shaped push-pull block 35 by moving up and down. The L-shaped push-pull block 35 drives the swing block 37 to move. When it is necessary to swing the electric telescopic rod 13, the second electric push rod 33 is started by powering on. The output end of the second electric push rod 33 drives the moving block 34 to move up and down. The moving block 34 drives the L-shaped push-pull block 35 to move. The L-shaped push-pull block 35 drives the swing block 37 to move. The swing block 37 moves, driving the swing sleeve 36 to move, which in turn drives the electric telescopic rod 13 to move. The electric telescopic rod 13 rotates with the transfer mechanism as the support point, causing the temperature sensor 14 to swing within the yogurt. This allows the temperature sensor 14 to move in three-dimensional space within the fermentation chamber 1, enabling the temperature detection equipment to monitor the temperature of the yogurt at different spatial locations within the fermentation chamber 1. This allows for timely and accurate temperature monitoring of local locations during the yogurt fermentation process, preventing temperature differences between local areas and other locations within the chamber due to undetected local temperatures, thus preventing abnormal local temperatures within the fermentation chamber and improving the quality of the fermented yogurt.

[0067] The adapter mechanism includes a support block 10, a wire groove 11, and a rotating block 12. The support block 10 is fixedly connected to the bottom of the support rod 9. The wire groove 11 is located at the side end of the support block 10 and extends into the support rod 9, the lifting block 5, and the lifting rod 7. The rotating block 12 is rotatably connected to the support block 10 through a hinge.

[0068] In this invention, the support block 10 is rotatably connected to the rotating block 12 via a hinge shaft. The wire groove 11 is used to accommodate the wire, facilitating the transmission of power and electrical information between the support rod 9 and the electric telescopic rod 13 via a line. The rotating block 12 is used to support and fix the electric telescopic rod 13. The wire groove 11 is opened in the lifting rod 7, lifting block 5, support rod 9 and support block 10 to accommodate the installation of the wire. The wire groove 11 not only avoids the wire from contacting the yogurt, reducing the contamination of the yogurt, but also prevents the wire groove 11 from breaking due to the rotation of the support rod 9, thus preventing the power transmission from being interrupted due to the breakage of the wire.

[0069] A sealing ring 15 is fitted on the circumferential surface of the support rod 9, and the sealing ring 15 is fixedly connected to the bottom of the rotating sleeve 3.

[0070] In this invention, the sealing ring 15 is installed at the bottom of the rotating sleeve 3 to seal the gap between the support rod 9 and the rotating sleeve 3, so as to prevent yogurt from seeping into the rotating sleeve 3 and to prevent debris generated by friction between the lifting block 5 and the rotating sleeve 3 from contaminating the yogurt.

[0071] Terminal 38 is fixedly connected to the top of the main body 1 of the fermentation chamber.

[0072] In this invention, the terminal 38 is electrically connected to the lifting motor 18, the drive motor 24, the ratchet 28, and the second electric push rod 33. The terminal 38 has a built-in storage module, a communication module, etc. The storage module stores the running program, and the communication module is used to exchange the collected temperature data with other devices in the temperature control system.

[0073] The working principle of a temperature control system for a yogurt fermentation chamber is as follows:

[0074] S1. When it is necessary to collect the temperature of the yogurt in the main body 1 of the fermentation chamber in a decentralized manner, the support rod 9 and the electric telescopic rod 13 are on the same vertical axis. The terminal 38 first turns on the power to start the lifting motor 18. The output end of the lifting motor 18 drives the lead screw 19 to rotate. The lead screw 19 drives the slider 20 to rise and fall through the sliding cooperation with the slider 20. The slider 20 drives the lifting rod 7 to rise and fall, so that the lifting rod 7 drives the lifting block 5 to rise and fall and slide in the rotating sleeve 3. Under the sliding cooperation of multiple guide blocks 4 and guide grooves 6, the lifting block 5 drives the support rod 9 to retract and move at the bottom of the rotating sleeve 3, pushing the support rod 9 out of the rotating sleeve 3. The support rod 9 pushes the support block 10 to move. The support block 10 pushes the electric telescopic rod 13 down through the sliding cooperation with the rotating block 12, and then inserts the electric telescopic rod 13 into the yogurt.

[0075] S2, the terminal 38 is powered on again to start the drive motor 24. The output end of the drive motor 24 drives the drive gear 26 to rotate. The drive gear 26 drives the driven gear 25 to rotate through meshing with the driven gear 25. The driven gear 25 drives the rotating sleeve 3 to rotate. The rotating sleeve 3 drives the lifting block 5 to rotate through the sliding cooperation of multiple rotating sleeves 3 and guide grooves 6. The lifting block 5 drives the support rod 9 to rotate. The support rod 9 drives the support block 10 to rotate. The support block 10 drives the rotating block 12 to rotate through the rotational cooperation with the rotating block 12, so that the temperature sensor 14 at the top of the electric telescopic rod 13 moves horizontally inside the yogurt.

[0076] S3, terminal 38 is powered on again to start the second electric push rod 33. The output end of the second electric push rod 33 pushes and pulls the moving block 34 to move up and down. The moving block 34 pushes and drives the L-shaped push-pull block 35 to move. When the L-shaped push-pull block 35 drives the swing block 37 to move, the swing block 37 drives the swing sleeve 36 to move. The swing sleeve 36 uses the shaft between the wire groove 11 and the rotating block 12 as the rotation support point, which facilitates the swing of the electric telescopic rod 13. This allows the temperature sensor 14 to perform three-dimensional temperature monitoring of the yogurt fermentation process through swinging. This allows the temperature detection equipment to monitor the temperature of the yogurt in different spatial locations in the fermentation chamber body 1. It enables timely and accurate temperature monitoring of local locations during the yogurt fermentation process, avoiding the difference between the local temperature and the temperature of other locations in the tank due to the inability to detect local temperatures. This prevents abnormal local temperatures in the fermentation chamber body and improves the quality of the fermented yogurt.
