Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food fermentation, in particular to a beef paste seal fermentation equipment and process capable of reducing flavor loss. BACKGROUND

[0002] As a fermented food with flavor levels and nutritional value, the core quality of beef paste depends on the metabolic activity of functional bacteria such as lactic acid bacteria and yeast bacteria in the fermentation process, and the retention efficiency of volatile flavor substances such as ethyl acetate and ethyl lactate. In the fermentation process, a stable micro-positive pressure environment can promote the ester and aroma production of bacteria, a low-oxygen atmosphere can inhibit the aerobic respiration of miscellaneous bacteria, and a sterile environment is the basis for avoiding the deterioration of fermented materials. All of the above are highly dependent on the sealing system performance of the fermentation equipment.

[0003] During the preparation of beef paste sauce in the sealed fermentation equipment, the gas generated in the fermentation process of the beef paste sauce raw materials in the fermentation equipment needs to be discharged through the exhaust mechanism in the fermentation equipment. However, in the process of filling the micro gaps of the equipment sealing surface by the elastic deformation sealing element (such as a sealing ring) to realize the isolation of the fermentation cabin from the outside world, the sealing element is prone to aging due to factors such as long-term compression, elastic attenuation, oxidation, etc., which in turn causes the surface of the sealing element to become brittle and cracked, and the mechanical wear produces rubber debris, eventually forming leakage pores, resulting in flavor loss of the sauce in the fermentation state in the fermentation equipment, microbial fermentation environment disorder, product contamination and other chain problems.

[0021] By adopting the above technical scheme, the ring-shaped sector formed by the mutual combination of the elastic sheets and the rubber sheets can collect the debris falling from the aging sealing ring.

[0022] The technical scheme of the present application provides a fermentation process of a beef paste sealing and fermentation equipment capable of reducing flavor loss, which comprises the following steps:

[0023] S1, first, the device in the process of fermentation of beef paste, the bottom of the valve seat under the action of its own gravity and the first elastic force and the flow cone surface and the surface of the sealing ring and fit, the flow cone surface is in a sealed state, while the storage cavity, cavity and vent groove inside all store high pressure gas, the third elastic element, the second elastic element and the fourth elastic element are all in compression state, the rubber sheet in the third sliding groove is in tension state, and the piston plate overcomes the elastic force of the third elastic element through the air pressure and its own gravity, the baffle overcomes the elastic force of the second elastic element and its own gravity through the air pressure below, and the baffle is in a balanced state at this time;

[0024] S2, due to the fermentation process will produce a large amount of gas, so that the gas pressure in the fermentation cabin increases, when the gas pressure exceeds the threshold value, it will overcome the gravity of the valve seat and the elastic force of the first elastic element, lift the valve seat, make the sliding plate and the first sliding groove slide and compress the first elastic element, at this time, the gas in the fermentation cabin is discharged from the exhaust pipe through the space between the valve seat and the flow cone surface and the sealing channel;

[0025] S3, and with the work of the device, the sealing ring will be aging under the action of long-term compression, dynamic stress damage and oxidation, the elasticity will decay, and the surface will gradually harden and become brittle, and finally cracks will appear, and when the elasticity decays to a certain extent, it will directly damage the balance of the sealing ring through elastic deformation to fill the micro concave-convex of the sealing surface of the storage cavity, and initial pores will be generated, at the same time, the sealing property of the sealing ring will also be reduced, at this time, the high pressure gas in the storage cavity will slowly discharge through the initial pores under the action of gas pressure, so that the gas pressure in the storage cavity is reduced;

[0026] S4, at this time, the reduction of the gas pressure in the storage cavity will destroy the balance of the baffle and the second elastic element, so that the baffle will rotate downward under the action of its own gravity and the elastic force of the second elastic element, opening the channel between the exhaust hole and the storage cavity, so that the gas in the storage cavity, cavity and vent groove is discharged quickly through the exhaust hole, with the rapid discharge of the gas, when the gas pressure in the cavity is reduced to less than the elastic force of the third elastic element, the piston plate will rise under the action of the third elastic element, compress the space in the cavity and speed up the discharge of the gas, at the same time, the gas pressure in the cavity plays a buffering role for the upward movement of the piston plate;

[0027] S5, when the piston plate goes up, the secondary sealing block will be driven up by the connecting plate, if the valve seat is in the state of abutting against the sealing ring at this time, the secondary sealing block will abut against and fit the bottom of the valve seat with the elastic ring, and cooperate with the aging sealing ring to seal the flow guide cone surface, and when the valve seat is lifted, the secondary sealing block will open the elastic ring, and part of the top of the secondary sealing block will be popped out of the second sliding groove above the flow guide cone surface, and the elastic ring will be bent to the side away from the sealing ring, and when the valve seat goes down again, it will extrude the secondary sealing block downward, so that part of the secondary sealing block is retracted into the second sliding groove, and the bent elastic ring will abut against and fit the side wall of the valve seat through its elasticity, and the secondary sealing block and the elastic ring will seal the flow guide cone surface;

[0028] S6, during the process of the piston plate going up, the clamping plate will go up to release the clamping of the clamping groove, at this time the second adjusting plate will slide in the third sliding groove under the action of the fourth elastic element, and will apply stress to the inner wall of the fourth sliding groove of the first adjusting plate on both sides, and will drive the first adjusting plate to slide through the stress, and the two sides of the second adjusting plate will also slide into the fourth sliding groove, and the sliding of the first adjusting plate and the second adjusting plate will drive the elastic sheet to move out of the third sliding groove, so that the annular sector formed by the combination of the elastic sheet and the rubber sheet moves below the flow guide cone surface and abuts against the conical surface at the bottom of the valve seat to collect the debris falling after the aging of the sealing ring, at this time, since the inner diameter and the outer diameter of the annular sector are reduced, the stretched rubber sheet will shrink to normal, and when the exhaust is performed, the exhaust gas will make the elastic sheet bend the rubber sheet towards the sealing ring, so as to wrap the collected debris;

[0029] S7, finally, during the process of periodically cleaning the fermentation cabin, if the secondary sealing block is popped out and the elastic sheet is located outside the third sliding groove, it indicates that the sealing ring has aged to a critical failure state, and needs to be replaced, and the elastic sheet, the baffle and the secondary sealing block are reset, and high-pressure gas is injected into the gas storage cavity.

[0030] Advantages: one or more technical solutions provided in the technical scheme have at least the following technical effects or advantages:

[0031] 1. After the initial pores are generated in the aging sealing ring, the pressure of the gas storage cavity is released to break the balance of the piston plate, so that the piston plate drives the secondary sealing block to pop out under the action of the third elastic element, realizes the sealing, avoids the sealing failure after the aging of the sealing ring, prevents the rapid loss of flavor substances in the fermentation cabin along with the internal gas, guarantees the rich taste of the beef paste, maintains the pressure in the fermentation cabin within a threshold range, and ensures the stable metabolic environment of lactic acid bacteria, yeast and other strains.

[0032] 2. Meanwhile, the sealing can also prevent external air from entering the fermentation cabin, causing the low-oxygen environment in the fermentation cabin to be affected, and avoiding external bacteria from entering the fermentation cabin to pollute the fermented material, reduce the speed or yield of flavor substances produced by microorganisms, or even cause the fermented material to deteriorate, thereby improving product quality.

[0033] 3. After the initial pores are generated in the aging sealing ring, the gas in the gas storage cavity leaks, causing the internal gas pressure to decrease, which breaks the balance of the baffle, causing the baffle to rotate downward under the action of the second elastic member to open the exhaust hole, so that the high-pressure gas in the gas storage cavity can be quickly discharged through the exhaust hole, and the upward movement of the piston plate accelerates the exhaust, achieving rapid response and avoiding the occurrence of sealing hysteresis caused by slow pressure reduction after the aging of the sealing ring.

[0034] 4. The elastic ring provided on the secondary sealing block can isolate the secondary sealing block from the outside when it is not in use, avoiding the surface oxidation or contamination of the secondary sealing block before it is used, ensuring the performance integrity of the standby state of the secondary sealing block, and ensuring the effectiveness of the emergency sealing.

[0035] 5. Meanwhile, when the secondary sealing block is expanded, the elastic ring bends away from the sealing ring, directing dust or contaminated foreign matter attached to the elastic ring to the non-fermentation area, avoiding the occurrence of contamination of the fermented material in the fermentation cabin.

[0036] 6. After the elastic ring is bent, the downward movement of the valve seat causes part of the secondary sealing block to retract into the second sliding groove, and the bent elastic ring is in contact with the side wall of the valve seat due to its elasticity, forming a sealing lip. The secondary sealing block and the elastic ring seal the flow guide cone surface, improving the sealing performance of the flow guide cone surface.

[0037] 7. During the above-mentioned secondary sealing block sealing process, the clamping of the clamping plate and the clamping groove is simultaneously released, causing the second adjusting plate to quickly drive the annular fan formed by the elastic sheet and the rubber sheet under the action of the fourth elastic member, and the annular fan is positioned below the flow guide cone surface and in contact with the conical surface at the bottom of the valve seat. The broken pieces falling from the aging sealing ring are collected, avoiding the contamination of the sauce material caused by the falling of the rubber pieces, and the quick ejection can avoid the leakage of some pieces caused by the time difference, which can cause the contamination of the sauce material.

[0038] 8. The airflow during exhaust drives the elastic sheet to bend the rubber sheet towards the sealing ring, wrapping the collected debris inside the annular fan, avoiding the blowing of the debris to the fermentation cabin or the dead angle of the equipment, and preventing the debris from mixing into the sauce material that is in the fermentation state, thereby affecting the quality of the sauce product.

[0039] 9. When staff members observe the secondary sealing block being pushed out and the elastic plate being outside the third sliding groove during regular cleaning or maintenance of this fermentation equipment, they can directly determine that the sealing ring has aged to the critical state of failure. This method is not only highly accurate but also does not require the use of professional testing equipment, making it easy to operate. Attached Figure Description

[0057] Reference Figures 2 to 8 This application provides a sealed fermentation device for beef sauce that can reduce flavor loss. The valve assembly 12 includes a sealed channel 127 disposed inside the top shell of the fermentation chamber 101. The inner wall of the sealed channel 127 is provided with a first groove 125. The interior of the sealed channel 127 is provided with a guide cone surface 128. The interior of the sealed channel 127 is provided with a valve seat 121. A slide plate 122 is fixedly connected to the side of the valve seat 121. A plurality of partitions 123 for blocking the first groove 125 are fixedly connected to the bottom of the slide plate 122. A plurality of diaphragms 124 are provided on the top of the slide plate 122. A plurality of first elastic elements 126 are provided on the top of the slide plate 122.

[0058] The number of baffles 123 is the same as the number of diaphragms 124. The bottom of the valve seat 121 is conical. The slide plate 122 is slidably connected to the inner wall of the first slide groove 125. The top of the diaphragm 124 is fixedly connected to the inner wall of the first slide groove 125. The top of the slide plate 122 is elastically connected to the inner wall of the first slide groove 125 through the first elastic element 126. The size of the bottom of the valve seat 121 is adapted to the size of the guide cone surface 128. An air storage chamber 14 is provided inside the guide cone surface 128.

The contact surface between the elastic ring 16 and the secondary sealing block 17 is smooth.

[0059] Reference Figure 3 , Figure 6 and Figure 7 This application provides a sealed fermentation device for beef sauce that can reduce flavor loss. The exhaust assembly 15 includes a plurality of exhaust holes 151 opened on the guide cone surface 128. A plurality of baffles 152 are provided on the top of the inner wall of the gas storage chamber 14. A second elastic member 153 is provided on the top of the baffles 152. The baffles 152 are rotatably connected to the inner wall of the gas storage chamber 14. The top of the baffles 152 is elastically connected to the inner wall of the gas storage chamber 14 through the second elastic member 153. The number of exhaust holes 151 is the same as the number of baffles 152. The bottom of the exhaust holes 151 communicates with the interior of the gas storage chamber 14.

[0060] After the sealing ring 13 ages and develops initial porosity, gas leakage occurs in the gas storage chamber 14, causing a decrease in its internal gas pressure. This disrupts the balance of the baffle 152, causing the baffle 152 to rotate downwards under the elastic force of the second elastic element 153, opening the exhaust port 151. This allows the high-pressure gas in the gas storage chamber 14 to be quickly discharged through the exhaust port 151. In conjunction with the upward movement of the piston plate 182, the exhaust is accelerated, achieving a rapid response and avoiding the sealing lag caused by the slow pressure drop after the sealing ring 13 ages. Furthermore, the elastic ring 16 on the secondary sealing block 17 isolates the secondary sealing block 17 from the outside when it is not in use, preventing the surface of the secondary sealing block 17 from oxidizing or being contaminated by the discharged gas before use. This ensures the performance integrity of the secondary sealing block 17 in its standby state and guarantees effective emergency sealing.

[0061] Meanwhile, when the secondary sealing block 17 unfolds, the elastic ring 16 bends away from the sealing ring 13, guiding the dust or contaminants attached to the elastic ring 16 to the non-fermentation area, preventing them from entering the fermentation chamber 101 and contaminating the fermented material. After the elastic ring 16 bends, the downward movement of the valve seat 121 will cause part of the secondary sealing block 17 to retract into the second slide groove 19, and the bent elastic ring 16 will abut against the side wall of the valve seat 121 through its own elasticity to form a sealing lip. The secondary sealing block 17 and the elastic ring 16 seal the guide cone surface 128, improving the sealing performance of the guide cone surface 128.

A plurality of ventilation slots 185 are disposed on the side of the cavity 184.

[0063] Piston plate 182 extends through the inner wall of second slide groove 19 into cavity 184. The bottom of piston plate 182 abuts against the bottom of inner wall of cavity 184. The bottom of piston plate 182 is elastically connected to inner wall of cavity 184 through third elastic member 183. The interior of cavity 184 is connected to interior of air storage cavity 14 through vent groove 185. The bottom of secondary sealing block 17 is fixedly connected to top of connecting plate 181. Several clamping plates 20 are fixedly connected to the bottom of piston plate 182. The several clamping plates 20 and several third elastic members 183 are staggered.

[0064] After the sealing ring 13 ages and produces initial pores, the gas storage chamber 14 depressurizes, disrupting the balance of the piston plate 182. Under the elastic force of the third elastic element 183, the piston plate 182 pushes out the secondary sealing block 17, achieving a resealing. This prevents the sealing ring 13 from failing after aging, thus avoiding the rapid loss of flavor substances in the fermentation chamber 101 with the internal gas. This ensures the rich flavor of the beef sauce and maintains the pressure in the fermentation chamber 101 within the threshold range, ensuring a stable metabolic environment for lactic acid bacteria, yeast, and other microorganisms. At the same time, the resealing also prevents external air from entering the fermentation chamber 101 and affecting the low-oxygen environment inside. It also prevents external bacteria from entering the fermentation chamber 101 and contaminating the fermentation material, reducing the rate or yield of flavor substances produced by microorganisms, or even causing the fermentation material to deteriorate, thereby improving product quality.

[0065] Reference Figures 3 to 10 This application provides a sealed fermentation device for beef sauce that can reduce flavor loss. The adjustment component 22 includes a plurality of first adjustment plates 221 and a plurality of second adjustment plates 224 slidably connected in the third slide groove 21. The first adjustment plates 221 are provided with fourth slide grooves 222 on both sides. The first adjustment plates 221 are provided with slots 223. The third slide groove 21 is provided with a plurality of fourth elastic members 225.

[0066] The number of first adjusting plates 221 is the same as the number of second adjusting plates 224. The two sides of the second adjusting plates 224 are slidably connected to the fourth sliding grooves 222 in the two first adjusting plates 221 respectively. A number of first adjusting plates 221 and a number of second adjusting plates 224 are alternately distributed and combined to form an annular adjusting component. Elastic sheets 23 are fixedly connected to both the first adjusting plates 221 and the second adjusting plates 224. Rubber sheets 24 are fixedly connected between the elastic sheets 23. A number of elastic sheets 23 and a number of rubber sheets 24 are combined to form an annular fan surface. The number of first adjusting plates 221 is the same as the number of clamping plates 20. The bottom of the clamping plate 20 extends through the inner wall of the cavity 184 to the interior of the third sliding groove 21. The bottom of the clamping plate 20 is engaged with the clamping groove 223. The number of fourth elastic elements 225 is the same as the number of second adjusting plates 224. The side of the second adjusting plate 224 away from the elastic sheet 23 is elastically connected to the inner wall of the third sliding groove 21 through the fourth elastic element 225.

[0067] During the resealing process of the secondary sealing block 17, the engagement between the card plate 20 and the card slot 223 is simultaneously released. Under the action of the elastic force of the fourth elastic element 225, the second adjusting plate 224 quickly moves the annular fan-shaped surface formed by the combination of the elastic sheet 23 and the rubber sheet 24 to the bottom of the guide cone surface 128 and abuts against the cone surface at the bottom of the valve seat 121. This collects the debris that falls off after the sealing ring 13 ages, preventing the aged rubber debris from entering the fermentation chamber 101 and causing the sauce to be contaminated and inedible. The rapid ejection also prevents some debris from leaking due to time difference, thus avoiding contamination of the sauce. During exhaust, the airflow drives the elastic sheet 23 to bend the rubber sheet 24 towards the sealing ring 13, wrapping the collected debris inside the annular fan-shaped surface. This prevents the airflow from blowing the debris into the fermentation chamber 101 or dead corners of the equipment, thus preventing debris from mixing into the sauce raw materials that are currently fermenting and affecting the quality of the sauce product.

[0068] This application provides a fermentation process for a sealed fermentation device for beef sauce that can reduce flavor loss, including the following steps.

[0069] S1. First, during the fermentation of beef sauce, the bottom of the valve seat 121 abuts against and fits against the surfaces of the guide cone 128 and the sealing ring 13 under its own weight and the elastic force of the first elastic element 126, so that the guide cone 128 is in a sealed state. At this time, the gas storage chamber 14, the cavity 184 and the ventilation groove 185 all store high-pressure gas. The third elastic element 183, the second elastic element 153 and the fourth elastic element 225 are all in a compressed state. The rubber sheet 24 stored in the third sliding groove 21 is in a stretched state. The piston plate 182 overcomes the elastic force of the third elastic element 183 by the air pressure above and its own weight. The baffle 152 overcomes the elastic force of the second elastic element 153 and its own weight by the air pressure below. At this time, the baffle 152 is in a balanced state.

[0070] S2. As a large amount of gas is generated during fermentation, the gas pressure in the fermentation chamber 101 increases. When the gas pressure exceeds the threshold, it will overcome the gravity of the valve seat 121 and the elastic force of the first elastic element 126, and lift the valve seat 121, so that the slide plate 122 slides with the first slide groove 125 and compresses the first elastic element 126. At this time, the gas in the fermentation chamber 101 is discharged from the exhaust pipe 11 through the space between the valve seat 121 and the guide cone surface 128 and the sealing channel 127.

[0071] S3. As the device operates, the sealing ring 13 will age under the effects of long-term compression, dynamic stress damage and oxidation, causing its elasticity to decrease and its surface to gradually harden and become brittle, eventually resulting in cracks. When the elasticity decreases to a certain extent, it will directly destroy the balance of the micro-unevenness of the sealing surface of the gas storage cavity 14 filled by the elastic deformation of the sealing ring 13, creating an initial pore. At the same time, the sealing performance of the sealing ring 13 will also decrease. At this time, the high-pressure gas in the gas storage cavity 14 will be slowly discharged through this initial pore under the action of air pressure, causing the air pressure in the gas storage cavity 14 to decrease.

[0072] S4. At this time, the decrease in air pressure in the air storage chamber 14 will disrupt the balance between the baffle 152 and the second elastic element 153, causing the baffle 152 to rotate downward under its own weight and the elastic force of the second elastic element 153, opening the channel between the exhaust port 151 and the air storage chamber 14, allowing the gas in the air storage chamber 14, the cavity 184 and the ventilation groove 185 to be quickly discharged through the exhaust port 151. As the gas is quickly discharged, when the air pressure in the cavity 184 decreases to a level that is less than the elastic force of the third elastic element 183 in conjunction with the weight of the piston plate 182, the piston plate 182 will move upward under the action of the elastic force of the third elastic element 183, compressing the space in the cavity 184 and accelerating the gas discharge. At the same time, the air pressure in the cavity 184 acts as a buffer for the upward movement of the piston plate 182.

[0073] S5. When the piston plate 182 moves upward, it will drive the secondary sealing block 17 upward through the connecting plate 181. If the valve seat 121 is in a state of abutting against the sealing ring 13 at this time, the secondary sealing block 17 will push against the elastic ring 16 and abut against and fit against the bottom of the valve seat 121, cooperating with the aged sealing ring 13 to seal the guide cone surface 128. When the valve seat 121 is lifted and in the exhaust state, the secondary sealing block 17 will push the elastic ring 16 open and push the secondary sealing block 17 against the elastic ring 16. Part of the valve seat 121 springs from the second slide groove 19 to the top of the guide cone surface 128, while the elastic ring 16 bends to the side of the secondary sealing block 17 away from the sealing ring 13. When the valve seat 121 moves down again, it will press the secondary sealing block 17 downward, causing part of the secondary sealing block 17 to retract into the second slide groove 19. The bent elastic ring 16 will abut against and fit against the side wall of the valve seat 121 through its own elasticity, thus sealing the guide cone surface 128 through the secondary sealing block 17 and the elastic ring 16.

[0074] S6. During the upward movement of the piston plate 182, it will drive the locking plate 20 upward, causing it to disengage from the locking groove 223. At this time, the second adjusting plate 224 will slide in the third sliding groove 21 under the action of the elastic force of the fourth elastic element 225, and apply stress to the inner wall of the fourth sliding groove 222 in the first adjusting plate 221 on both sides. The stress will drive the first adjusting plate 221 to slide, and the two sides of the second adjusting plate 224 will also slide into the fourth sliding groove 222. The sliding of the first adjusting plate 221 and the second adjusting plate 224 will... The elastic sheet 23 is moved out of the third slide groove 21, so that the annular fan formed by the combination of the elastic sheet 23 and the rubber sheet 24 moves to the bottom of the guide cone 128 and abuts against the cone surface at the bottom of the valve seat 121 to collect the debris that falls off after the sealing ring 13 ages. At this time, since the inner and outer diameters of the annular fan are reduced, the stretched rubber sheet 24 will shrink to its normal state. When the exhaust is performed, the exhaust airflow will cause the elastic sheet 23 to drive the rubber sheet 24 to bend towards the sealing ring 13, wrapping the collected debris.

[0075] S7. Finally, during the regular cleaning of the fermentation chamber 101, if the secondary sealing block 17 is found to be pushed out and the elastic plate 23 is located outside the third sliding groove 21, it indicates that the sealing ring 13 has aged to the critical state of failure. This method is not only highly accurate, but also does not require the use of professional testing equipment and has a low operating threshold. At this time, it is necessary to replace it, and reset the elastic plate 23, baffle 152 and secondary sealing block 17, and inject high-pressure gas into the gas storage chamber 14.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.

10. The fermentation process of a sealed fermentation device for beef sauce that reduces flavor loss according to claim 9, characterized in that, Includes the following steps: S1. First, during the fermentation of beef sauce, the bottom of the valve seat (121) abuts against and fits against the surfaces of the guide cone (128) and the sealing ring (13) under the action of its own weight and the elastic force of the first elastic element (126), so that the guide cone (128) is in a sealed state. At this time, the gas storage chamber (14), the cavity (184) and the ventilation groove (185) all store high-pressure gas. The third elastic element (183), the second elastic element (153) and the fourth elastic element (225) are all in a compressed state. The rubber sheet (24) stored in the third slide groove (21) is in a stretched state. The piston plate (182) overcomes the elastic force of the third elastic element (183) by the air pressure above and its own weight. The baffle (152) overcomes the elastic force of the second elastic element (153) and its own weight by the air pressure below. At this time, the baffle (152) is in a balanced state. S2. As a large amount of gas is generated during the fermentation process, the gas pressure in the fermentation chamber (101) increases. When the gas pressure exceeds the threshold, it will overcome the gravity of the valve seat (121) and the elastic force of the first elastic element (126), lift the valve seat (121), and make the slide plate (122) slide with the first slide groove (125) and compress the first elastic element (126). At this time, the gas in the fermentation chamber (101) is discharged from the exhaust pipe (11) through the space between the valve seat (121) and the guide cone surface (128) and the sealing channel (127). S3. As the device works, the sealing ring (13) will age under the effects of long-term compression, dynamic stress damage and oxidation, causing its elasticity to decrease and its surface to gradually harden and become brittle, eventually resulting in cracks. When the elasticity decreases to a certain extent, it will directly destroy the balance of the micro-concave and convex surfaces of the sealing surface of the gas storage cavity (14) filled by the elastic deformation of the sealing ring (13), creating an initial pore. At the same time, the sealing performance of the sealing ring (13) will also decrease. At this time, the high-pressure gas in the gas storage cavity (14) will slowly discharge through this initial pore under the action of the gas pressure, causing the gas pressure in the gas storage cavity (14) to decrease. S4. At this time, the decrease in air pressure in the gas storage chamber (14) will disrupt the balance between the baffle (152) and the second elastic element (153), causing the baffle (152) to rotate downward under its own weight and the elastic force of the second elastic element (153), opening the channel between the exhaust hole (151) and the gas storage chamber (14), allowing the gas in the gas storage chamber (14), cavity (184) and ventilation groove (185) to be quickly discharged through the exhaust hole (151). As the gas is quickly discharged, when the air pressure in the cavity (184) decreases to a level that is less than the elastic force of the third elastic element (183) in conjunction with the weight of the piston plate (182), the piston plate (182) will move upward under the action of the elastic force of the third elastic element (183), compressing the space in the cavity (184) and accelerating the gas discharge. At the same time, the air pressure in the cavity (184) will buffer the upward movement of the piston plate (182). S5. When the piston plate (182) moves upward, it will drive the secondary sealing block (17) upward through the connecting plate (181). If the valve seat (121) is in a state of abutting against the sealing ring (13) at this time, the secondary sealing block (17) will push against the elastic ring (16) and abut against and fit against the bottom of the valve seat (121), cooperating with the aged sealing ring (13) to seal the guide cone surface (128). When the valve seat (121) is lifted and is in the exhaust state, the secondary sealing block (17) will push open the elastic ring (16) and make the secondary sealing block (17) push against the elastic ring (16). Part of the flow guide cone (128) springs from the second slide groove (19) to the top of the flow guide cone (128), while the elastic ring (16) bends to the side of the secondary sealing block (17) away from the sealing ring (13). When the valve seat (121) moves down again, it will press down on the secondary sealing block (17), causing part of the secondary sealing block (17) to retract into the second slide groove (19). The bent elastic ring (16) will abut against and fit against the side wall of the valve seat (121) through its own elasticity, and seal the flow guide cone (128) through the secondary sealing block (17) and the elastic ring (16). S6. During the upward movement of the piston plate (182), it will drive the clamping plate (20) upward to disengage it from the clamping groove (223). At this time, the second adjusting plate (224) will slide in the third sliding groove (21) under the action of the elastic force of the fourth elastic element (225), and apply stress to the inner wall of the fourth sliding groove (222) in the first adjusting plate (221) on both sides. The stress will drive the first adjusting plate (221) to slide, and the two sides of the second adjusting plate (224) will also slide into the fourth sliding groove (222). The first adjusting plate (221) and the second adjusting plate (224) slide... The movement will cause the elastic sheet (23) to move out of the third groove (21), so that the annular fan formed by the combination of the elastic sheet (23) and the rubber sheet (24) moves to the bottom of the guide cone (128) and abuts against the cone at the bottom of the valve seat (121) to collect the debris that falls off after the sealing ring (13) ages. At this time, since the inner and outer diameters of the annular fan are reduced, the stretched rubber sheet (24) will shrink to its normal state. When the exhaust is performed, the exhaust airflow will cause the elastic sheet (23) to drive the rubber sheet (24) to bend towards the sealing ring (13) and wrap the collected debris. S7. Finally, during the regular cleaning of the fermentation chamber (101), if the secondary sealing block (17) is found to be pushed out and the elastic plate (23) is located outside the third slide groove (21), it indicates that the sealing ring (13) has aged to the critical state of failure and needs to be replaced. The elastic plate (23), baffle (152) and secondary sealing block (17) should be reset, and high-pressure gas should be injected into the gas storage chamber (14).
