The starch of rice is saccharified by the strong action of Aspergillus' amylase. Therefore, it has been used as a raw material of sugar together with malt to make wine, sweet wine and bean paste since ancient times. Liquor is produced by microbial fermentation of grain, and koji provides the initial microorganism for fermentation and is the direct driving force of the entire fermentation. Therefore, the fermentation of koji is generally carried out at a constant temperature;

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 8 As shown, the constant temperature equipment for koji fermentation of the present invention comprises a temperature regulating component 1;

[0039] The temperature control component 1 is composed of an internal unit 11 and an external unit 12; the internal unit 11 is connected to the external unit 12; the internal unit 11 is arranged in the fermentation room for adjusting the indoor temperature; the internal unit 11 adjusts the air temperature in the fermentation room and then sprays it out, and the principle of the temperature control component 1 is the same as the principle of air conditioning in the prior art;

[0040] The koji fermentation equipment also includes a temperature measuring component 2 and a controller;

[0041] The temperature measuring component 2 comprises:

[0042] A center rod 21; one end of the center rod 21 is fixedly connected to a disc 22, and the other end is fixedly connected to a ball 23;

[0043] The sleeve 24 is sleeved on the middle part of the center rod 21; one end of the sleeve 24 close to the first disc 22 is fixedly connected to the second disc 25, and the other end is fixedly connected to the external thread sleeve 26; the outer diameter of the external thread sleeve 26 decreases as it moves away from the sleeve 24; the second disc 25 is slidably connected to the center rod 21;

[0044] Internal thread sleeve 27; the internal thread sleeve 27 is sleeved on the center rod 21; the internal thread sleeve 27 is threadedly connected to the external thread sleeve 26; the outer wall of the internal thread sleeve 26 is evenly provided with notches 261; when the internal thread sleeve 27 is tightened close to the external thread sleeve 26, the external thread sleeve 26 is tightened under pressure, thereby increasing the friction between the external thread sleeve 26 and the center rod 21;

[0045] Elastic rods 28; a plurality of the elastic rods 28 are connected between the first disc 22 and the second disc 25; the elastic rods 28 are made of an elastic material, such as rubber;

[0046] Temperature sensor 29; the temperature sensor 29 is embedded in the outer wall of the elastic rod 28; the sensor is a contact sensor, which has higher measurement accuracy than non-contact sensors, and the temperature sensor 29 is fixedly connected to the outer wall of the elastic rod 28 away from the central rod 21; the temperature sensor 29 transmits the measured temperature result to the controller, and the controller controls the temperature regulating component 1 to regulate the temperature of the fermentation chamber;

[0047] Controller; the controller is used to control the automatic operation of the present invention; the injection molded parts of the present invention can be formed by half injection molding and then bonding;

[0048] When working, the existing temperature measuring component 2 measures the temperature of the air in the fermentation room. However, in the actual fermentation process, the temperature of the koji blocks is different from the temperature in the air, and the temperature of the densely stacked koji blocks and the sparsely stacked koji blocks is also different. The inaccurate temperature measured by the existing temperature measuring component 2 will affect the fermentation effect of the koji.

[0049] Therefore, after the koji blocks are made, they are stacked in the fermentation room, and then the temperature measuring assembly 2 is held by hand, and the outer wall of the center rod 21 close to the ball 23 is held to move the entire temperature measuring assembly 2 to the gap between adjacent koji blocks. Then, the sleeve 24 is held with one hand, and the internal threaded sleeve 27 is held with the other hand. The internal threaded sleeve 27 is twisted away from the sleeve 24, so that the internal threaded sleeve 27 is loosened from the external threaded sleeve 26, so that the internal threaded sleeve 27 is unlocked from the external threaded sleeve 26, that is, the external threaded sleeve 26 is unlocked on the center rod 21, and then the external threaded sleeve 26 is pushed to move along the center rod 21 away from the ball 23. During the movement of the external threaded sleeve 26, the sleeve 24 and the second disc 25 are driven to move synchronously, so that the second disc 25 The elastic rod 28 moves close to the No. 1 disc 22, and the elastic force of the inner half of the elastic rod 28 is greater than the elastic force of the outer half, so the elastic rod 28 will arch outward under extrusion, and the temperature sensor 29 will be driven to move close to the curved block during the arching process of the elastic rod 28. After arching, the multiple elastic rods 28 drive the temperature sensor 29 to fit on the outer wall of the corresponding curved block, and then tighten the internal threaded sleeve 27. By tightening the internal threaded sleeve 27, the internal threaded sleeve 27 is driven to move close to the sleeve 24. During the tightening process of the internal threaded sleeve 27, the inner wall diameter of the external threaded sleeve 26 will become smaller, and the external threaded sleeve 26 will gradually tighten, so that the pressure between the inner wall of the external threaded sleeve 26 and the center rod 21 will slowly increase. The internal threaded sleeve 27 is tightened to the limit position and then released, that is, it is complete. The purpose of locking the internal threaded sleeve 27 and the external threaded sleeve 26 is achieved. The static friction between the external threaded sleeve 26 and the center rod 21 makes the external threaded sleeve 26 locked to the corresponding position of the center rod 21, that is, the sleeve 24 is locked to the corresponding position of the center rod 21, thereby maintaining the deformation degree of the elastic rod 28, and maintaining the elastic rod 28 to drive the temperature sensor 29 to measure the temperature in real time. There are gaps between the elastic rods 28, and the gas can flow through the gaps between the elastic rods 28, so that the air permeability between the blocks will not be affected by the existence of the temperature measuring component 2, thereby ensuring the fermentation effect, and the temperature sensor 29 will sense the temperature on the corresponding block, thereby transmitting the temperature of the block to the controller, and the controller will transmit these temperature data The value is averaged and then transmitted to the temperature control component 1. The temperature control component 1 determines whether it needs to be heated up or cooled down according to the temperature value given by the controller until the values ​​of each temperature sensor 29 meet the value range of the fermentation of the koji. After the fermentation temperature is in the constant temperature range, the fermentation process is completed after a period of time. Then, the temperature measuring component 2 is recovered according to the above method, and the fermented koji blocks are subjected to the next process; the temperature measuring component 2 can measure multiple koji blocks at one time, and the controller calculates the average value of the koji, so that the temperature measurement result is more accurate. At the same time, measuring the temperature in the gap between the koji blocks can avoid damage to the koji blocks during the temperature measurement process to the greatest extent; the temperature measuring components 2 are all made of lightweight materials, so as to avoid the situation of crushing the koji blocks;By holding the center rod 21 with one hand and rotating the sleeve 24 with the other hand, the sleeve 24 drives the second disc 25 to rotate, and the second disc 25 rotates relative to the first disc 22, so that the elastic rod 28 can be twisted, thereby changing the direction in which the elastic rod 28 arches;

[0050] The present invention measures the temperature by clamping the temperature sensor 29 on the temperature measuring component 2 between the koji blocks, thereby making the temperature measurement more accurate while avoiding damage to the koji blocks caused by the temperature measurement, thereby allowing the koji blocks to ferment stably under a constant temperature environment, which is more accurate than the temperature measurement in the prior art; the more accurate the temperature measurement, the more accurate the temperature adjustment, and the better the fermentation effect.

[0051] As an embodiment of the present invention, a sliding hole 251 is provided at a position corresponding to the end surface of the second disc 25 and the elastic rod 28; a threaded hole 252 is fixedly connected to the side wall of the second disc 25; the threaded hole 252 is connected to the corresponding sliding hole 251; a bolt 253 is connected to the inner thread of the threaded hole 252; one end of the bolt 253 close to the threaded hole 252 is connected to a rubber pad 254; one end of the elastic rod 28 away from the first disc 22 is slidably connected to the sliding hole 251;

[0052] During operation, before the staff inserts the temperature measuring component 2 between the adjacent curved blocks, they first observe the shape and position of the gap between the curved blocks, and then estimate the position of the temperature measuring component 2 after being inserted into the gap between the curved blocks, and then determine how many elastic rods 28 are needed, which position of the elastic rods 28 need to be driven, and whether the length ratio of each elastic rod 28 is appropriate. The reason is that after the elastic rods 28 are arched, some elastic rods 28 have already contacted the corresponding curved blocks and cannot continue to move, which will limit the elastic rods 28 that are not in contact with the curved blocks from continuing to arch, so these two need to be adjusted. The lengths of the elastic rods 28 need to be different. At the same time, some elastic rods 28 do not contact the curved block even if they are arched, so this elastic rod 28 is not needed. In this way, the staff of the present invention makes a judgment in advance, that is, first loosen the bolt 253, so that the bolt 253 moves away from the sliding hole 251 along the threaded hole 252 after being screwed, so that the state in which the bolt 253 drives the rubber pad 254 to fit the outer wall of the elastic rod 28 becomes a distant state, and one end of the elastic rod 28 can slide freely along the sliding hole 251 without being squeezed by the bolt 253, so that by pulling The elastic rod 28 or the second disc 25 is moved, thereby adjusting the length of the elastic rod 28 between the first disc 22 and the second disc 25, so that each position corresponds to the required length of the elastic rod 28, and then tightening the corresponding bolt 253 according to the elastic rod 28 that needs to be arched. During the tightening process, the thread moves along the threaded hole 252 close to the sliding hole 251, so that the rubber pad 254 is pressed by the bolt 253 to fit the outer wall of the elastic rod 28, so that one end of the elastic rod 28 is locked with the second disc 25, and after the elastic rod 28 is adjusted, the temperature measuring group 253 is set. Component 2 moves to the gap between adjacent curved blocks, and then pushes the sleeve 24 to drive the second disc 25 to move close to the first disc 22, so that each elastic rod 28 arches to different degrees, thereby maximizing the fit of the temperature sensor 29 to the outer surface of the curved block, thereby expanding the measurement range. The larger the measurement range, the larger the base of the average value, that is, the higher the accuracy of the measured temperature, and the better the temperature control effect; the purpose of the rubber pad 254 is to avoid the situation where the bolt 253 directly contacts the elastic rod 28 and causes the outer wall of the elastic rod 28 and the temperature sensor 29 to be scratched.

[0053] As an embodiment of the present invention, a circular groove 255 is provided on the end surface of the bolt 253 close to the sliding hole 251; the rubber pad 254 is slidably connected in the circular groove 255; the rubber pad 254 and the circular groove 255 are connected by a spring 256;

[0054] During operation, when the bolt 253 is tightened, the bolt 253 will move along the threaded hole 252 close to the sliding hole 251, and the bolt 253 will drive the spring 256 and the rubber pad 254 to move close to the sliding hole 251, so that the rubber pad 254 contacts the outer wall of the elastic rod 28 in the sliding hole 251, and at the same time, the spring 256 is compressed to a certain extent, so that the spring 256 has a certain squeezing force on the outer wall of the elastic rod 28 through the rubber pad 254, that is, there is a certain static friction between the rubber pad 254 and the elastic rod 28, and in the process of the elastic rod 28 in the gap between the curved blocks being pushed by the second disc 25 to arch The arched part of the elastic rod 28 will contact the koji block, and under the blocking limit of the koji block, the elastic rod 28 cannot continue to move. In the process that the second disc 25 continues to push the elastic rod 28, the force of the koji block to limit the elastic rod 28 will overcome the static friction between the rubber pad 254 and the elastic rod 28, so that one end of the elastic rod 28 will slide along the sliding hole 251 to achieve force unloading, thereby avoiding the situation where the elastic rod 28 is squeezed and breaks the surface of the koji block, thereby maximizing the measurement while protecting the koji block; the breakage of the koji block affects the fermentation effect of the koji and increases the difficulty of transportation.

[0055] As an embodiment of the present invention, the other end of the elastic rod 28 has an angle with the center rod 21 in the initial state; one end of the elastic rod 28 has a tendency to move outward without the restriction of the second disc 25; the end of the elastic rod 28 away from the first disc 22 is fixedly connected to the limit block 281;

[0056] During operation, when the bolt 253 is loosened, that is, when the bolt 253 is away from the sliding hole 251, one end of the elastic rod 28 is not hindered in the movement of the sliding hole 251, and under the action of the limit block 281, the second disc 25 and the first disc 22 move to the maximum limit distance, and then the temperature measuring component 2 is placed in the gap between the curved blocks, and finally the second disc 25 is pushed to make the second disc 25 move close to the first disc 22. During the movement of the second disc 25, one end of the elastic rod 28 will slide along the sliding hole 251, so that the elastic rod 28 is not limited by the second disc 25, and one end of the elastic rod 28 itself has a tendency to move outward. Therefore, after the second disc 25 is away from the elastic rod 28, one end of the elastic rod 28 will open outward, so that the elastic rod 28 fits with the surrounding curved block surface after opening, and then the elastic rod 28 drives the embedded temperature sensor 29 to contact the curved block surface to achieve temperature sensing. The method is simpler and more convenient to operate. It is suitable for gaps of various specifications and shapes of koji blocks. At the same time, the opening method of the elastic rod 28 does not affect the addition of partition grass. The purpose of adding partition grass is to isolate the koji blocks, increase air permeability, and absorb the water vapor generated by the koji blocks during fermentation. After the elastic rod 28 is opened without the second disc 25, the staff will lock the sleeve 24 through the internal threaded sleeve 27 and the external threaded sleeve 26. After the fermentation is completed, the external threaded sleeve 26 is unlocked. 6 and the internal threaded sleeve 27, and then pull the sleeve 24 to drive the second disc 25 to move away from the first disc 22, so that the second disc 25 tightens the other end of the elastic rod 28 while folding the partition grass together, thereby facilitating the folding of the partition grass. After the temperature measuring component 2 with the folded partition grass is moved to the specified area, the elastic rod 28 is opened again, and the partition grass falls into the specified area under the action of gravity. The elastic rod 28 is limited by the second disc 25 again without the obstruction of the partition grass.

[0057] As an embodiment of the present invention, both ends of the sliding hole 251 are fixedly connected to the annular sleeve 3; the inner diameter of the annular sleeve 3 increases as it moves away from the sliding hole 251; the temperature sensor 29 protrudes from the outer wall of the elastic rod 28;

[0058] During operation, by protruding the temperature sensor 29 out of the outer wall of the elastic rod 28, the elastic rod 28 can slightly embed into the outer wall of the curved block when the temperature sensor 29 is pressed against the outer wall of the curved block, thereby making the temperature sensed by the temperature sensor 29 more accurate. At the same time, the inner wall specification of the annular sleeve 3 away from the sliding hole 251 is larger than the sum of the cross-sections of the elastic rod 28 and the temperature sensor 29. At the same time, the inner wall specification of the sliding hole 251 is larger than the sum of the cross-sections of the elastic rod 28 and the temperature sensor 29. Therefore, during the relative displacement between the sliding hole 251 and the elastic rod 28 on the second disk 25, the temperature sensor 29 on the elastic rod 28 will contact the inner wall of the annular sleeve 3, and the temperature sensor 29 will be squeezed by the inner wall of the annular sleeve 3, thereby guiding the temperature sensor 29 and preventing the protruding temperature sensor 29 from being scratched by the sliding hole 251.

[0059] As an embodiment of the present invention, the inner wall of the annular sleeve 3 is hinged with a brush 31; the hinge point of the brush 31 is fixedly connected to the outer wall of the sliding hole 251 with a limiting rod 32; the brush 31 is perpendicular to the inner wall of the annular sleeve 3 under the limiting effect of the limiting rod 32; the brush 31 and the limiting rod 32 are elastic and will not affect the guiding of the elastic rod 28 and the temperature sensor 29 by the annular sleeve;

[0060] During operation, when the sliding hole 251 approaches the first disk 22 along the elastic rod 28, the brush 31 in the annular sleeve 3 on the side of the second disk 25 close to the first disk 22 rotates under the friction of the elastic rod 28, and due to the limiting effect of the limiting rod 32, the brush 31 on the side of the second disk 25 close to the first disk 22 is perpendicular to the inner wall of the annular sleeve 3, that is, the brush 31 in the annular sleeve 3 on the side of the second disk 25 close to the first disk 22 scrapes the outer surface of the moving elastic rod 28, so that impurities on the surfaces of the elastic rod 28 and the temperature sensor 29 are cleaned, and friction is also generated between the brush 31 in the annular sleeve 3 on the side of the second disk 25 away from the first disk 22 and the elastic rod 28, so that the brush 31 in the annular sleeve 3 on the side of the second disk 25 away from the first disk 22 The brush 31 rotates under the action of friction, so that the brush 31 on the side of the second disk 25 away from the first disk 22 throws out the attached impurities after rotation; conversely, in the process of the sliding hole 251 moving away from the first disk 22 along the elastic rod 28, the brush 31 close to the first disk 22 rotates under the action of friction and throws off the attached impurities, while the brush 31 away from the first disk 22 scrapes the outer wall of the elastic rod 28 under the action of the limiting rod 32, thereby achieving the cleaning purpose; the elastic rod 28 is cleaned by the brushes 31 at two locations, so that the temperature sensor 29 on the cleaned elastic rod 28 has no impurities attached, and the impurities attached to the surface of the temperature sensor 29 will not affect the sensing accuracy, thereby greatly improving the measurement accuracy of the temperature measuring component 2.

[0061] As an embodiment of the present invention, the inner wall of the sleeve 24 is provided with an annular cavity 241; both ends of the sleeve 24 are connected to the center rod 21 in a sliding and sealing manner; the annular cavity 241 is connected to an annular plate 242 in a sliding and sealing manner; the inner wall of the annular plate 242 is fixedly connected to the outer wall of the center rod 21; the annular plate 242 divides the annular cavity 241 into an upper cavity 243 and a lower cavity 244; the outer wall of the sleeve 24 is provided with a No. 1 air inlet hole 245 and a No. 2 air inlet hole 246; the No. 1 air inlet hole 245 is connected to the upper cavity 243; The second air inlet 246 is connected to the lower chamber 244; the sleeve 24 is provided with a first air outlet 247 and a second air outlet 248; one end of the first air outlet 247 is connected to the upper chamber 243, and the other end is connected to the inner wall of the slide hole 251; one end of the second air outlet 248 is connected to the lower chamber 244, and the other end is connected to the inner wall of the slide hole 251; one-way air inlet valves are provided in the first air inlet 245 and the second air inlet 246; one-way air outlet valves are provided in the first air outlet 247 and the second air outlet 248;

[0062] During operation, when the sliding hole 251 approaches the No. 1 disc 22, the annular plate 242 moves along the annular cavity 241, so that the air inside the upper cavity 243 is squeezed. At the same time, the space of the lower cavity 244 is expanded, and the internal gas of the upper cavity 243 is squeezed and filled into the corresponding sliding hole 251 along the No. 1 air outlet 247, thereby impacting the overturned brush 31 with air flow to make impurities fall off, and also impacting the impurities attached to the surface of the elastic rod 28. Since the space of the lower cavity 244 is expanded, the outside air enters the lower cavity 244 along the No. 2 air inlet 246 to replenish the internal gas of the lower cavity 244. Then, when the sliding hole 251 moves away from the No. 2 disc 25, the annular plate 242 moves along the annular cavity 243 again. 41 moves, thereby squeezing the gas on the inner wall of the lower chamber 244. At the same time, the space of the upper chamber 243 is expanded. The internal gas of the lower chamber 244 is squeezed and then filled into the corresponding sliding hole 251 along the No. 2 air outlet hole 248, thereby performing a gas impact on the other flipped brush 31 to make impurities fall off. At the same time, it also impacts the impurities attached to the surface of the elastic rod 28. Since the air in the upper chamber 243 is expanded, the outside gas enters the upper chamber 243 along the No. 1 air inlet hole 245 to replenish the internal gas of the upper chamber 243. In this way, each time the sleeve 24 moves along the center rod 21, one of the flipped brushes 31 can be cleaned, thereby ensuring the cleaning effect of the brush 31 on the outer wall of the elastic rod 28.

[0063] As an embodiment of the present invention, a circular cavity 211 is provided inside the center rod 21 near the first disc 22; an air hole 212 is provided on the outer wall of the center rod 21; the air hole 212 is communicated with the circular cavity 211; a desiccant 213 is contained in the circular cavity 211; the outer wall of one end of the sleeve 24 away from the second disc 25 is fixedly connected to the annular shell 4; an opening is provided on one end of the annular shell 4 near the second disc 25;

[0064] During operation, when the bolt 253 is away from the sliding hole 251, the sleeve 24 is pushed to slide along the center rod 21, and at the same time, one end of the elastic rod 28 is gathered by hand, so that one end of the elastic rod 28 moves to the inner side of the annular shell 4 under the guidance of the hand, so that the temperature sensor 29 on the inner elastic rod 28 is dustproof and protected by the annular shell 4. At the same time, the sleeve 24 also covers the air hole 212 on the center rod 21. After the sleeve 24 moves away from the No. 1 disk 22, the elastic rod 28 is pulled out from the inside of the annular shell 4, and the air tube is exposed after the sleeve 24 is removed, so that the water vapor generated during the fermentation process can enter the circular cavity 211 from the air hole 212, and then be adsorbed by the desiccant 213 in the circular cavity 211. The desiccant 213 can be replaced by opening a replacement window on the outer wall of the center rod 21.

[0065] The specific workflow is as follows:

[0066] After the koji blocks are made, they are stacked in the fermentation room, and then the temperature measuring assembly 2 is held by hand, and the outer wall of the center rod 21 close to the ball 23 is held to move the entire temperature measuring assembly 2 to the gap between adjacent koji blocks. Then, the sleeve 24 is held with one hand, and the internal threaded sleeve 27 is held with the other hand. The internal threaded sleeve 27 is twisted away from the sleeve 24, so that the internal threaded sleeve 27 is loosened from the external threaded sleeve 26, so that the internal threaded sleeve 27 is unlocked from the external threaded sleeve 26, that is, the external threaded sleeve 26 is unlocked on the center rod 21, and then the external threaded sleeve 26 is pushed to move along the center rod 21 away from the ball 23. During the movement of the external threaded sleeve 26, the sleeve 24 and the second disc 25 are driven synchronously The movement causes the second disc 25 to move closer to the first disc 22, and the elastic force of the inner half of the elastic rod 28 is greater than the elastic force of the outer half, so the elastic rod 28 will arch outward under the extrusion, and the temperature sensor 29 will be driven to move closer to the curved block during the arching process of the elastic rod 28. After arching, the multiple elastic rods 28 drive the temperature sensors 29 to fit on the outer wall of the corresponding curved block, and then tighten the internal threaded sleeve 27. By tightening the internal threaded sleeve 27, the internal threaded sleeve 27 is driven to move closer to the sleeve 24. During the tightening process of the internal threaded sleeve 27, the inner wall diameter of the external threaded sleeve 26 will become smaller, and the external threaded sleeve 26 will gradually tighten, so that the pressure between the inner wall of the external threaded sleeve 26 and the center rod 21 is reduced. The strength is slowly increased, and the internal threaded sleeve 27 is loosened after being tightened to the limit position, that is, the purpose of locking the internal threaded sleeve 27 and the external threaded sleeve 26 is completed. The static friction between the external threaded sleeve 26 and the center rod 21 makes the external threaded sleeve 26 locked to the corresponding position of the center rod 21, that is, the sleeve 24 is locked to the corresponding position of the center rod 21, thereby maintaining the deformation degree of the elastic rod 28, and maintaining the elastic rod 28 to drive the temperature sensor 29 to measure the temperature in real time. There are gaps between the elastic rods 28, and the gas can flow through the gaps between the elastic rods 28. The temperature sensor 29 will sense the temperature on the corresponding curved block, thereby transmitting the temperature of the curved block to the controller. The controller will The temperature value is averaged and then transmitted to the temperature control component 1. The temperature control component 1 determines whether it needs to be heated up or cooled down according to the temperature value given by the controller until the values ​​of each temperature sensor 29 meet the value range of the fermentation of the wine koji. After the fermentation temperature is in the constant temperature range, the fermentation process is completed after a period of time. Then, the temperature measuring component 2 is recovered according to the above method, and the fermented koji block is subjected to the next process; the central rod 21 is held by one hand, and the sleeve 24 is rotated by the other hand, so that the sleeve 24 drives the second disc 25 to rotate, and the second disc 25 will rotate relative to the first disc 22, so that the elastic rod 28 can be twisted, and then the direction of the elastic rod 28 can be changed;

[0067] The staff first loosens the bolt 253, so that the bolt 253 moves away from the sliding hole 251 along the threaded hole 252 after being screwed, so that the bolt 253 drives the rubber pad 254 to change the state of being in contact with the outer wall of the elastic rod 28 to a state of being away from each other. In the absence of the bolt 253 squeezing, one end of the elastic rod 28 can slide freely along the sliding hole 251, so that by pulling the elastic rod 28 or moving the second disk 25, the length of the elastic rod 28 between the first disk 22 and the second disk 25 is adjusted, so that each The position corresponds to the required length of the elastic rod 28, and then the corresponding bolt 253 is tightened according to the elastic rod 28 that needs to be arched. The thread moves along the threaded hole 252 close to the sliding hole 251 during the tightening process, so that the rubber pad 254 is pressed by the bolt 253 to fit the outer wall of the elastic rod 28, so that one end of the elastic rod 28 is locked with the second disk 25. After the elastic rod 28 is adjusted, the temperature measuring component 2 is moved to the gap between the adjacent curved blocks, and then the sleeve 24 is pushed to drive the second disk 25 close to the first disk 22. The spring 256 and the rubber pad 254 are moved so that each elastic rod 28 is arched to different degrees; when the bolt 253 is tightened, the bolt 253 moves along the threaded hole 252 close to the sliding hole 251, and the bolt 253 drives the spring 256 and the rubber pad 254 to move close to the sliding hole 251, so that the rubber pad 254 contacts the outer wall of the elastic rod 28 in the sliding hole 251, and the spring 256 is compressed to a certain extent, so that the spring 256 has a certain squeezing force on the outer wall of the elastic rod 28 through the rubber pad 254, that is, the rubber pad 254 and the rubber pad 254 are pressed together. There is a certain static friction between the elastic rods 28. When the elastic rod 28 in the gap between the curved blocks is pushed by the second disc 25 and arched, the arched part of the elastic rod 28 will contact the curved block. Under the blocking limit of the curved block, the elastic rod 28 cannot continue to move. When the second disc 25 continues to push the elastic rod 28, the force of the curved block on the elastic rod 28 will overcome the static friction between the rubber pad 254 and the elastic rod 28, so that one end of the elastic rod 28 will slide along the sliding hole 251 to achieve force unloading.When the bolt 253 is loosened, that is, when the bolt 253 is moving away from the sliding hole 251, one end of the elastic rod 28 is not hindered in the movement of the sliding hole 251, and under the action of the limit block 281, the second disk 25 and the first disk 22 move to the maximum limit distance, and then the temperature measuring component 2 is placed in the gap between the curved blocks, and finally the second disk 25 is pushed to make the second disk 25 move closer to the first disk 22. During the movement of the second disk 25, one end of the elastic rod 28 will slide along the sliding hole 251, so that the elastic rod 28 is not limited by the second disk 25, and one end of the elastic rod 28 itself has a tendency to move outward, so when the second disk 25 is away from After the elastic rod 28 is pulled out, one end of the elastic rod 28 will open outward, so that the elastic rod 28 fits with the surrounding curved block surface after opening, and the staff then locks the sleeve 24 through the internal threaded sleeve 27 and the external threaded sleeve 26. After the fermentation is completed, the external threaded sleeve 26 and the internal threaded sleeve 27 are unlocked, and then the sleeve 24 is pulled to drive the second disc 25 to move away from the first disc 22, so that the second disc 25 tightens the other end of the elastic rod 28 while folding the partition grass out. After the temperature measuring component 2 with the partition grass folded is moved to the specified area, the elastic rod 28 is opened again, and the partition grass falls into the specified area under the action of gravity. The elastic rod 28 is again The second disc 25 is limited; by protruding the temperature sensor 29 from the outer wall of the elastic rod 28, the temperature sensor 29 can be slightly embedded in the outer wall of the curved block when the elastic rod 28 presses the temperature sensor 29 against the outer wall of the curved block. At the same time, during the relative displacement between the sliding hole 251 on the second disc 25 and the elastic rod 28, the temperature sensor 29 on the elastic rod 28 will contact the inner wall of the annular sleeve 3, and the temperature sensor 29 will be squeezed by the inner wall of the annular sleeve 3, thereby guiding the temperature sensor 29; during the process of the sliding hole 251 approaching the first disc 22 along the elastic rod 28, the brush 31 in the annular sleeve 3 on the side of the second disc 25 close to the first disc 22 is pressed against the elastic rod 2 8 rotates under the action of the friction force of the limiting rod 32, and due to the limiting effect of the limiting rod 32, the brush 31 on the side of the second disc 25 close to the first disc 22 is perpendicular to the inner wall of the annular sleeve 3, that is, the brush 31 in the annular sleeve 3 on the side of the second disc 25 close to the first disc 22 scrapes the outer surface of the moving elastic rod 28, and the brush 31 in the annular sleeve 3 on the side of the second disc 25 away from the first disc 22 and the elastic rod 28 also generate friction, so that the brush 31 on the side of the second disc 25 away from the first disc 22 rotates under the action of the friction force, so that the brush 31 on the side of the second disc 25 away from the first disc 22 throws out the attached impurities after rotation;On the contrary, when the sliding hole 251 moves away from the No. 1 disc 22 along the elastic rod 28, the brush 31 close to the No. 1 disc 22 rotates under the action of friction and throws away the impurities attached to it, while the brush 31 away from the No. 1 disc 22 scrapes the outer wall of the elastic rod 28 under the action of the limiting rod 32; when the sliding hole 251 moves toward the No. 1 disc 22, the annular plate 242 moves along the annular cavity 241, so that the air inside the upper cavity 243 is squeezed, and at the same time, the space of the lower cavity 244 is expanded, and the air inside the upper cavity 243 is compressed. The compressed air will flow into the corresponding sliding hole 251 along the first air outlet 247, thereby impacting the flipped brush 31 with air flow, and also impacting the impurities attached to the surface of the elastic rod 28. Since the space of the lower chamber 244 is expanded, the external air enters the lower chamber 244 along the second air inlet 246 to replenish the internal air of the lower chamber 244. Subsequently, when the sliding hole 251 moves away from the second disc 25, the annular plate 242 moves along the annular chamber 241 again, thereby squeezing the air on the inner wall of the lower chamber 244. When the air in the upper chamber 243 is expanded, the internal gas of the lower chamber 244 is squeezed and then flows into the corresponding sliding hole 251 along the second air outlet 248, thereby performing a gas impact on the other flipped brush 31, and also impacting the impurities attached to the surface of the elastic rod 28. Since the air in the upper chamber 243 is expanded, the external gas flows into the upper chamber 243 along the first air inlet 245, and replenishes the internal gas of the upper chamber 243. When the bolt 253 is away from the sliding hole 251, the sleeve 24 is pushed along the center rod 21. Slide, and at the same time, one end of the elastic rod 28 is gathered by hand, so that one end of the elastic rod 28 moves to the inner side of the annular shell 4 under the guidance of the hand, and at the same time, the sleeve 24 also covers the air hole 212 on the central rod 21, and after the sleeve 24 moves away from the first disc 22, the elastic rod 28 is pulled out from the inside of the annular shell 4, and the air tube is exposed after the sleeve 24 is removed, so that the water vapor generated during the fermentation process can enter the circular cavity 211 from the air hole 212 and then be adsorbed by the desiccant 213 in the circular cavity 211. ;
