Description

Technical Field

[0001] The present invention relates to the technical field of red yeast rice fermentation, and in particular to a Tibetan red yeast rice bag-type intelligent fermentation device and a fermentation process. Background Art

[0002] Existing red yeast rice products such as Tibetan red yeast rice are made by inoculating the seeds of grass plants (such as rice, highland barley, etc.) with Aspergillus strains and then fermenting them artificially. They have extremely high commercial value and broad development prospects. In the preparation process of red yeast rice, the fermentation culture of the matrix is ​​one of the key process steps, and the fermentation culture time is generally long. In research and development experiments or industrial production, transparent culture bottles such as triangular flasks are often used for closed culture and fermentation, but there are problems such as low yield and troublesome operation. In this regard, in the prior art, such as the preparation method of a lipid-lowering red yeast rice disclosed in Chinese patent document CN116616407A, the high-yield MonacolinK purple red yeast rice strain disclosed in CN111534443A and the method for fermenting and producing functional red yeast rice, all use fermentation bags to carry out bag fermentation of red yeast rice, which is beneficial to further reduce costs, To improve the yield, however, in the existing red yeast bag fermentation, manual turning is required. Considering that the bag fermentation matrix is ​​not light and the fermentation cycle requires multiple turnings, especially for batch industrial production, the turning timing of each fermentation bag may also deviate, requiring staff to perform multiple manual turning operations at different time points, which is relatively tedious and laborious. If intelligent mechanical equipment such as a robotic arm is used to automatically turn each fermentation bag, the robotic arm needs to accurately move to the designated turning position of each fermentation bag. Position deviation may cause damage to the equipment or damage to the mycelium inside the fermentation bag, so the precision requirement is high and the initial investment is large. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to propose a Tibetan red yeast bag-type intelligent fermentation device and fermentation process to solve the problem that the manual turning of the existing bag-type red yeast fermentation is cumbersome and laborious, and the use of intelligent turning robot arm equipment has high precision requirements and large initial investment.

[0004] Based on the above objectives, the present invention provides a safflower bag-type intelligent fermentation device, including a fermentation bag:

[0005] A strip inner bag is attached to the inner wall of the fermentation bag, the length direction of the strip inner bag is parallel to the length direction of the fermentation bag, and multiple strip inner bags are arranged closely along the width direction of the fermentation bag, including odd-numbered rows of inner bags and even-numbered rows of inner bags;

[0006] One end of the strip-shaped inner bag is connected to an inflation port, the inflation port of each odd-numbered row of inner bags is externally connected to an odd-numbered row of pipes, and the inflation port of each even-numbered row of inner bags is externally connected to an even-numbered row of pipes. One end of the odd-numbered row of pipes and the even-numbered row of pipes are respectively connected to an air pump. The air pump works by suction to exchange air between the odd-numbered row of inner bags and the even-numbered row of inner bags, so that the odd-numbered row of inner bags or the even-numbered row of inner bags are inflated to form a strip-shaped air column.

[0007] The fermentation bag is filled with fermentation matrix, and the strip inner bag is placed horizontally with one side facing down. The fermentation matrix is ​​filled in the gaps between the strip air columns. When it needs to be turned over, the air pump is controlled to suck until the odd-numbered inner bags and the even-numbered inner bags are ventilated with each other.

[0008] Preferably, the strip-shaped air column is designed in a semi-cylindrical shape, with a flat side of the semi-cylinder attached to the inner wall of the fermentation bag and an arched side of the semi-cylinder facing the hollow interior of the fermentation bag.

[0009] Preferably, one end of the odd-numbered columns of pipes are respectively connected to the first air outlet pipe and the first air inlet pipe, and one end of the even-numbered columns of pipes are respectively connected to the second air outlet pipe and the second air inlet pipe, and the first air outlet pipe, the first air inlet pipe, the second air outlet pipe and the second air inlet pipe are respectively provided with switch valves, the first air inlet pipe and the second air inlet pipe are connected to the air inlet end of the air pump, and the first air outlet pipe and the second air outlet pipe are connected to the air outlet end of the air pump.

[0010] Preferably, the first air outlet pipe, the first air inlet pipe, the second air outlet pipe and the second air inlet pipe are respectively provided with a one-way valve for controlling the one-way air intake of the first air inlet pipe and the second air inlet pipe, and the one-way air outlet of the first air outlet pipe and the second air outlet pipe.

[0012] Preferably, a temperature sensor is provided on the inner wall of the strip inner bag close to the fermentation bag, and the fermentation matrix in the gap presses the strip inner bag downward and is close to the temperature sensor. When the temperature sensor senses that the temperature exceeds a preset value, the air pump suction operation is triggered.

[0013] Preferably, an L-shaped connecting rod is movably connected to the inner wall of the strip inner bag away from the fermentation bag, and a ventilation position is provided on the inner wall of the strip inner bag away from the fermentation bag. The ventilation position is composed of a double-layered ventilation surface, and a plurality of ventilation holes are provided on the ventilation surface. A draw rope is connected to the ventilation surface of the inner layer, and one end of the draw rope is connected to the short rod part of the L-shaped connecting rod. When the strip inner bag is inflated to form a strip air column, the double-layer ventilation surfaces are attached to each other, and the ventilation holes of the inner and outer layers are staggered. When the strip inner bag is deflated so that the fermentation matrix moves downward to the temperature sensor, the long rod part of the L-shaped connecting rod is pushed by the temperature sensor, so that the L-shaped connecting rod pulls the draw rope downward, and the draw rope pulls the ventilation surface of the inner layer downward to form a gap between the ventilation surfaces of the inner and outer layers.

[0014] Preferably, the odd-numbered pipes and the even-numbered pipes are respectively connected with ventilation pipes, through which air is ventilated into the strip-shaped inner bag, and the air is ventilated into the pile of fermentation matrix through the gaps and air holes, so as to cool down the pile of fermentation matrix and supply oxygen.

[0015] The present invention also provides a safflower bag-type intelligent fermentation process, comprising the following steps:

[0016] A certain amount of plant seeds are placed in a fermentation bag, which is then hydrated and sterilized to serve as a fermentation matrix. The fermentation matrix is ​​then inoculated with a corresponding Aspergillus strain. The fermentation bag is placed on a work platform in a culture room and kept in a horizontal position to begin fermentation.

[0017] Among them, multiple strip-shaped inner bags are arranged closely along the width direction of the fermentation bag, including odd-numbered inner bags and even-numbered inner bags. Each odd-numbered inner bag or each even-numbered inner bag is inflated to form a strip-shaped air column, and the fermentation matrix is ​​naturally filled in the gap between the strip-shaped air columns. When the fermentation bag needs to be turned over, the air pump is controlled to suck air between the odd-numbered inner bags and the even-numbered inner bags to complete a complete physical turning over action.

[0018] Preferably, a temperature sensor is provided on the inner wall of the strip inner bag close to the fermentation bag. When the temperature sensor senses that the temperature exceeds a preset value, the air pump is triggered to pump and complete a turning action.

[0019] The bag is then tightened so that the bag can be taken out of the airtight container and the bag is in a closed position so that the bag can be taken out of the airtight container and the bag is in a closed position.

[0020] The beneficial effects of the present invention are as follows: a plurality of strip-shaped inner bags are arranged closely along the width direction of the fermentation bag, including odd-numbered row inner bags and even-numbered row inner bags, each odd-numbered row inner bag or each even-numbered row inner bag is inflated to form a strip-shaped air column, one end of the strip-shaped inner bag is connected to an inflation port, the inflation port of each odd-numbered row inner bag is externally connected to an odd-numbered row pipe, and the inflation port of each even-numbered row inner bag is externally connected to an even-numbered row pipe, one end of the odd-numbered row pipe and the even-numbered row pipe are respectively connected to an air pump, the fermentation bag is filled with fermentation substrate, and the strip-shaped inner bag is placed horizontally with one side facing downward, the fermentation substrate is filled in the gap between the strip-shaped air columns, and fermentation and cultivation are started. When turning the yeast is required, the air pump is controlled to suck air between the odd-numbered row inner bags and the even-numbered row inner bags to complete a complete physical turning action, without the need for tedious and laborious manual turning, and without the need for investment in equipment such as intelligent turning robotic arms, and the design is simple and reasonable.

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] like Figure 1 、 Figure 2 、 Figure 7As shown, a saffron bag-type intelligent fermentation device includes a fermentation bag 100, a strip inner bag 1 is attached to the inner wall of the fermentation bag 100, the length direction of the strip inner bag 1 is parallel to the length direction of the fermentation bag 100, and a plurality of strip inner bags 1 are arranged closely along the width direction of the fermentation bag 100, including odd-numbered rows of inner bags and even-numbered rows of inner bags. One end of the strip inner bag 1 is connected to an inflation port 2, and the inflation port 2 of each odd-numbered row of inner bags is externally connected to an odd-numbered row of pipes 3, and the inflation port 2 of each even-numbered row of inner bags is externally connected to an even-numbered row of pipes 4. One end of the odd-numbered row pipe 3 and the even-numbered row pipe 4 are respectively connected to the air pump 5, and the air pump 5 is used for suction to exchange air between the inner bags in the odd-numbered row and the inner bags in the even-numbered row, so that each inner bag in the odd-numbered row or each inner bag in the even-numbered row is inflated to form a strip air column 6. The fermentation bag 100 is filled with a fermentation matrix 200, and the strip inner bag 1 is placed horizontally with one side facing down. The fermentation matrix 200 is filled in the gap between the strip air columns 6. When it needs to be turned over, the air pump 5 is controlled to suck until the inner bags in the odd-numbered row and the inner bags in the even-numbered row are ventilated with each other.

[0034] The present invention is based on the existing conventional bag-type red yeast fermentation device and process, including a fermentation bag 100, such as Figure 1 As shown, the fermentation bag 100 is generally designed to be in a rectangular shape, and a seal 101 is provided on one side of the fermentation bag 100. A breathing valve 102 may also be provided on the fermentation bag 100 (to ensure oxygen circulation in the bag and maintain an appropriate oxygen concentration). When in use, the seal 101 is opened, and certain plant seeds (such as rice, barley, etc.) are placed in the fermentation bag 100, and a preliminary water replenishment and sterilization treatment is performed to serve as the fermentation matrix 200. Then, the corresponding Aspergillus strain is taken to inoculate the fermentation matrix 200, and the seal 101 is sealed (to prevent external bacteria contamination). The fermentation bag 100 is placed on the work platform in the culture room and kept in a horizontal position. The culture room maintains certain temperature and humidity process conditions, and fermentation culture begins. The fermentation matrix 200 is generally filled to less than half of the space in the fermentation bag 100. The fermentation time generally lasts for dozens of days. During this period, the fermentation state needs to be observed, and the koji operation is performed several times at intervals. After the fermentation is completed, the matrix is ​​sterilized and dried to obtain the corresponding red yeast product.

[0035] Among them, in the bag-type red yeast rice fermentation process, turning the koji is one of the key process steps. Considering that heat is released during the metabolism of red yeast rice, and red yeast rice is generally an aerobic bacterium, its mycelial growth and the synthesis of secondary metabolites depend on oxygen. Therefore, after a long time, inside the heap of the fermentation matrix 200 (especially when the mycelium is dense in the middle and late stages of fermentation), heat is difficult to diffuse outward and internal oxygen deficiency may cause the mycelial activity to decrease or even autolyze. In addition, the internal high-temperature anaerobic area is also suitable for the proliferation and growth of high-temperature resistant anaerobic bacteria (such as lactic acid bacteria, Bacillus, etc.). Therefore, turning the koji is a physical way of turning the fermentation matrix 200, so that the deep material is turned to the surface, avoiding metabolic stagnation due to local overheating or hypoxia, and is beneficial to the uniform distribution of temperature and oxygen in the matrix, thereby ensuring product quality. The existing conventional turning method is to manually turn the fermentation bag 100 or use an intelligent robotic arm to automatically turn the bag;

[0036] In the present invention, in particular, Figure 1 、 Figure 2 、 Figure 7 As shown, a strip inner bag 1 is attached to the inner wall of the fermentation bag 100. The length direction of the strip inner bag 1 is parallel to the length direction of the fermentation bag 100. A plurality of strip inner bags 1 are arranged closely along the width direction of the fermentation bag 100, including odd-numbered rows of inner bags and even-numbered rows of inner bags, for example Figure 2 As shown, along the width direction of the fermentation bag 100, the 1st, 3rd, 5th, 7th and 9th strip-shaped inner bags 1 are odd-numbered inner bags, and the 2nd, 4th, 6th and 8th strip-shaped inner bags 1 are even-numbered inner bags. One end of the strip-shaped inner bag 1 is connected to an inflation port 2, and one end of the inflation port 2 passes through the fermentation bag 100. The inflation port 2 of each odd-numbered inner bag is externally connected to an odd-numbered pipe 3, and the inflation port 2 of each even-numbered inner bag is externally connected to an even-numbered pipe 4. One end of the odd-numbered pipe 3 and the even-numbered pipe 4 are respectively connected to an air pump 5. The odd-numbered row pipe 3 and the even-numbered row pipe 4 respectively include a bronchial pipe connected to one end of the inflation port 2 and a confluence pipe connected to one end of the bronchial pipe. One end of the confluence pipe is connected to the air pump 5. The air pump 5 is used to pump air between the inner bags in the odd-numbered row and the inner bags in the even-numbered row, so that each inner bag in the odd-numbered row or each inner bag in the even-numbered row is inflated to form a strip-shaped air column 6. When in use, based on the same process steps as above, the fermentation bag 100 is filled with the fermentation matrix 200, and the strip-shaped inner bag 1 is placed horizontally with one side facing downwards, as shown in FIG. Figure 2 As shown, the fermentation matrix 200 is naturally filled in the gaps between the strip-shaped air columns 6. When bending is required, it is only necessary to control the air pump 5 to pump, for example Figure 2As shown, the gas in the odd-numbered row inner bags is gradually exchanged into the even-numbered row inner bags, that is, the even-numbered row inner bags gradually push up the fermentation matrix 200, the odd-numbered row inner bags gradually collapse, and the outer layer of the fermentation matrix 200 gradually falls onto the collapsed odd-numbered row inner bags, so that the matrix of the outer layer of the original pile turns to the inner layer of the pile, and the matrix of the inner layer of the original pile turns to the outer layer of the pile, until the odd-numbered row inner bags and the even-numbered row inner bags complete mutual ventilation, as shown in FIG. Figure 7 As shown, a complete physical turning action is completed. Compared with the traditional turning method, there is no need to operate tedious and laborious manual turning, nor is there any need to invest in equipment such as intelligent turning robotic arms. The design is simple and reasonable.

[0037] In an embodiment of the present invention, optionally, Figure 2 、 Figure 7 As shown, the strip-shaped air column 6 is designed in a semi-cylindrical shape, and the flat side of the semi-cylinder is attached to the inner wall of the fermentation bag 100 , and the arched side of the semi-cylinder faces the hollow interior of the fermentation bag 100 .

[0038] In an embodiment of the present invention, optionally, Figure 2 、 Figure 7 As shown, one end of the odd-numbered pipes 3 (i.e., one end of the pipes 3 merging into the odd-numbered pipes 3) is respectively connected to the first air outlet pipe 31 and the first air inlet pipe 32, and one end of the even-numbered pipes 4 (i.e., one end of the pipes 4 merging into the even-numbered pipes 4) is respectively connected to the second air outlet pipe 41 and the second air inlet pipe 42. The first air outlet pipe 31, the first air inlet pipe 32, the second air outlet pipe 41, and the second air inlet pipe 42 are respectively provided with a switch valve 7. The switch valve 7 can adopt an existing conventional switch control valve, solenoid valve, and other components for controlling the on-off of the air pipe. Among them, the first air inlet pipe 32 and the second air inlet pipe 42 are connected to the air inlet end of the air pump 5, and the first air outlet pipe 31 and the second air outlet pipe 41 are connected to the air outlet end of the air pump 5, and each switch valve 7 is initially in a normally closed state, for example Figure 2 As shown, when the bend needs to be turned, the switch valve 7 on the first air outlet pipe 31 and the second air inlet pipe 42 is controlled to be opened, and the other switch valves 7 remain closed, and the air pump 5 is controlled to suck, and the gas in the odd-numbered inner bags is gradually replaced into the even-numbered inner bags. Conversely, the switch valve 7 on the first air inlet pipe 32 and the second air outlet pipe 41 is controlled to be opened, and the other switch valves 7 remain closed, and the air pump 5 is controlled to suck, and the gas in the even-numbered inner bags is gradually replaced into the odd-numbered inner bags.

[0039] In an embodiment of the present invention, optionally, Figure 2 、 Figure 7As shown, a one-way valve 8 is respectively provided on the first air outlet pipe 31, the first air inlet pipe 32, the second air outlet pipe 41 and the second air inlet pipe 42. The one-way valve 8 adopts the existing conventional one-way valve components, check valve components and other components used on the air pipe, and is used to control the one-way air intake of the first air inlet pipe 32 and the second air inlet pipe 42, and the one-way air outlet of the first air outlet pipe 31 and the second air outlet pipe 41.

[0040] In an embodiment of the present invention, optionally, Figure 2 、 Figure 7 As shown, pressure gauges 9 are respectively provided on the odd-numbered pipes 3 and the even-numbered pipes 4 for monitoring the air pressure in the odd-numbered inner bags and the even-numbered inner bags.

[0041] In an embodiment of the present invention, optionally, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a temperature sensor 10 is provided on the inner wall of the strip-shaped inner bag 1 close to the fermentation bag 100. The temperature sensor 10 can be a conventional sensor that can sense temperature and convert it into a usable output signal. In fact, a thermometer and hygrometer will also be provided in the culture chamber where the fermentation bag 100 is placed, which is mainly used to monitor the temperature and humidity in the entire culture chamber to ensure the overall fermentation and cultivation conditions. The temperature sensor 10 in the strip-shaped inner bag 1 mainly plays two roles. On the one hand, when the inner bags in each odd-numbered row or each even-numbered row are inflated to form a strip-shaped air column 6, the temperature sensor 10 in the strip-shaped air column 6 is mainly used to monitor the temperature of the gas in the inner bag to avoid affecting the fermentation and cultivation of the fermentation matrix 200. On the other hand, when the fermentation matrix 200 in the gap presses downward against the strip-shaped inner bag 1 and comes close to the temperature sensor 10, the temperature of the inner layer of the fermentation matrix 200 is mainly monitored through the temperature sensor 10. At this time, when the temperature sensed by the temperature sensor 10 exceeds the preset value, it means that the temperature of the inner layer exceeds the threshold value. At this time, the air pump 5 is triggered to suck, realizing the intelligent triggering of the turning action.

[0042] Among them, such as Figure 2 、 Figure 3 As shown, the temperature sensors 10 are symmetrically distributed along both sides of each odd-numbered column inner bag and each even-numbered column inner bag. More preferably, multiple temperature sensors are spaced apart along the length direction of both sides of the inner bag to facilitate more comprehensive temperature monitoring.

[0043] In an embodiment of the present invention, optionally, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7As shown, an L-shaped connecting rod 11 is movably connected to the inner wall of the strip inner bag 1 away from the fermentation bag 100. The L-shaped connecting rod 11 is arranged corresponding to the temperature sensor 10, wherein the corner of the L-shaped connecting rod 11 can be connected to the inner wall of the fermentation bag 100 through a connecting block. The connecting block can be made of conventional materials such as rubber with good deformation resistance, deformation recovery ability and toughness to achieve a movable connection. A vent position 12 is provided on the inner wall of the strip inner bag 1 away from the fermentation bag 100. Specifically, the vent position 12 can be designed in the shape of a long rectangle, and the vent position The length direction of 12 is parallel to the length direction of the fermentation bag 100. The air-permeable portion 12 is composed of a double-layered air-permeable surface 120. The air-permeable surface 120 can be made of the same material as the fermentation bag 100. A plurality of air holes are provided on the air-permeable surface 120. More preferably, each air hole can be provided with a breathable membrane, a filter and other structures to facilitate the passage of gas and prevent the passage of moisture, solid matrix and the like. A drawstring 13 is connected to the air-permeable surface 120 of the inner layer. One end of the drawstring 13 is connected to the short rod portion of the L-shaped connecting rod 11. When the strip-shaped inner bag 1 is inflated to form a strip air column 6, as shown in FIG. Figure 3 、 Figure 4 As shown, under the action of air pressure and the elastic restoring force of the inner breathable surface 120 and the elastic restoring force of the connecting block, the double-layer breathable surface 120 is attached to each other, and the breathable holes of the inner and outer layers are staggered. At this time, the breathable position 12 is in a closed state. When the strip-shaped inner bag 1 is deflated and collapsed, as shown in FIG. Figure 5 、 Figure 6 As shown, the fermentation matrix 200 is moved downwardly toward the temperature sensor 10. Under the pressure of the gravity of the fermentation matrix 200, the long rod portion of the L-shaped connecting rod 11 is pressed against the temperature sensor 10. The temperature sensor 10 pushes the long rod portion of the L-shaped connecting rod 11, so that the L-shaped connecting rod 11 pulls the drawstring 13 downwardly, and the drawstring 13 pulls the air permeable surface 120 of the inner layer downwardly. The air permeable surface 120 of the inner layer elastically expands downwardly to form a gap 121 between the air permeable surfaces 120 of the inner and outer layers, thereby forming a certain ventilation state between the inner layer pile of the fermentation matrix 200 and the strip-shaped inner bag 1, which is beneficial to the heat dissipation and oxygen supply of the inner layer pile.

[0044] Preferably, the ventilation position 12 is located on the side of the L-shaped connecting rod 11 away from the temperature sensor 10. The temperature sensor 10 senses the temperature of the inner layer of the fermentation matrix 200 through the sensing head at its top to avoid interference with ventilation. An extension plate can be added to the middle of the temperature sensor 10 to facilitate stable resistance to the L-shaped connecting rod 11.

[0045] In an embodiment of the present invention, optionally, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7As shown, odd-numbered pipes 3 (convergence pipe part) and even-numbered pipes 4 (convergence pipe part) are respectively connected to ventilation pipes 14. In one embodiment, the outer end of the ventilation pipe 14 can be directly opened, and an adjusting screw cap for adjusting the air intake can be provided at the opening. The adjusting screw cap is in an initial normally closed state to avoid affecting the turning operation. After the turning operation, the adjusting screw cap of the ventilation pipe 14 connected to the inner bag in the collapsed state can be opened, so that the air in the culture chamber is introduced into the collapsed inner bag through the ventilation pipe 14 and supplied to the inner layer of the fermentation matrix 200. In another embodiment, an air storage tank 15 is also included. Sterilized air or sterilized oxygen is stored in the air storage tank 15. Each ventilation pipe 14 is divided into They are respectively connected to the gas storage tank 15, and each vent pipe 14 is provided with a switch control valve component for controlling the on and off of the vent pipe 14. The switch control valve component is also in the initial normally closed state to avoid affecting the turning operation. After the turning operation, the switch control valve component of the vent pipe 14 connected to the inner bag in the collapsed state can be opened, and ventilation is allowed into the strip inner bag 1 through the vent pipe 14. The slowly replenished sterilized air or sterilized oxygen penetrates into the pile of the fermentation matrix 200 (especially the inner layer of the pushing material) through the gap 121 and the air vent, and is used to cool the pile of the fermentation matrix 200 (especially the inner layer of the pushing material) and supply oxygen, so as to avoid abnormal temperature rise and bacteria death in the fermentation and cultivation process, and avoid too high a turning frequency.

[0046] The gas used for mutual ventilation between the inner bags in the odd-numbered rows and the inner bags in the even-numbered rows can be sterile air or sterile oxygen.

[0047] In addition, when bending, if the pressure gauge 9 detects that the air pressure in the strip air column 6 is not up to standard, the corresponding switch control valve can be opened, and sterilized air or sterilized oxygen can be added or pumped in through the air storage tank 15 until the inflation pressure in the strip air column 6 reaches the standard.

[0048] The present invention also provides a safflower bag-type intelligent fermentation process, comprising the following steps:

[0049] A certain amount of plant seeds are placed in a fermentation bag 100, hydrated and sterilized to form a fermentation substrate 200. The fermentation substrate 200 is then inoculated with a corresponding Aspergillus strain. The fermentation bag 100 is placed on a work platform in a culture chamber and kept in a horizontal position to begin fermentation.

[0050] Among them, multiple strip-shaped inner bags 1 are arranged closely along the width direction of the fermentation bag 100, including odd-numbered inner bags and even-numbered inner bags. Each odd-numbered inner bag or each even-numbered inner bag is inflated to form a strip-shaped air column 6, and the fermentation matrix 200 is naturally filled in the gap between each strip-shaped air column 6. When it is necessary to turn the bag, the air pump 5 is controlled to suck and is used to exchange air between the odd-numbered inner bags and the even-numbered inner bags to complete a complete physical turning action.

[0051] Preferably, a temperature sensor 10 is provided on the inner wall of the strip-shaped inner bag 1 close to the fermentation bag 100. When the temperature sensor 10 senses that the temperature exceeds a preset value, the air pump 5 is triggered to pump, completing a turning action.

[0052] An L-shaped connecting rod 11 is movably connected to the inner wall of the strip inner bag 1 away from the fermentation bag 100. A ventilation position 12 is provided on the inner wall of the strip inner bag 1 away from the fermentation bag 100. The ventilation position 12 is composed of a double-layered ventilation surface 120. A plurality of ventilation holes are opened on the ventilation surface 120. A drawstring 13 is connected to the ventilation surface 120 of the inner layer. One end of the drawstring 13 is connected to the short rod part of the L-shaped connecting rod 11. The strip inner bag 1 is inflated to form a strip. When the air column 6 is formed, the double-layer air permeable surfaces 120 are attached to each other, and the air holes of the inner and outer layers are staggered. When the strip-shaped inner bag 1 is deflated and collapses, the temperature sensor 10 pushes the long rod part of the L-shaped connecting rod 11, so that the L-shaped connecting rod 11 pulls the drawstring 13 downward, and the drawstring 13 pulls the air permeable surface 120 of the inner layer downward, so that a gap 121 is formed between the air permeable surfaces 120 of the inner and outer layers, which is used to dissipate heat and supply oxygen to the inner layer pile of the fermentation matrix 200.
