Description

Technical Field

[0001] This invention belongs to the field of Armillaria mellea fermentation technology, and particularly relates to an Armillaria mellea fermentation apparatus and method. Background Technology

[0002] Armillaria mellea is a facultative parasitic fungus that has a symbiotic relationship with Gastrodia elata (a valuable traditional Chinese medicine). Gastrodia elata itself has no roots or chlorophyll and cannot perform photosynthesis. The nutrients it needs for growth are mainly obtained by digesting the mycelium of Armillaria mellea that invades its body.

[0003] The fermentation of Armillaria mellea requires a fermentation device. This involves placing the mycelium and nutrient solution into the device, simultaneously aerating it. A stirring rack within the device mixes and stirs the mycelium, nutrient solution, and oxygen, thus initiating fermentation. However, some existing fermentation devices use a relatively simple method for stirring the mycelium, nutrient solution, and oxygen, resulting in uneven dissolved oxygen distribution. This leads to insufficient oxygen uptake by some mycelium cells, and the lack of oxygen directly inhibits mycelial cell respiration and ATP synthesis, thereby reducing the overall fermentation effect of Armillaria mellea. Summary of the Invention

[0004] This invention provides an Armillaria mellea fermentation device and method, aiming to solve the problem mentioned in the background art, where the existing fermentation devices have a relatively simple stirring method for Armillaria mellea, nutrient solution and oxygen, resulting in uneven internal dissolved oxygen distribution, insufficient oxygen absorption by some mycelia, and reduced overall fermentation effect of Armillaria mellea.

[0007] Preferably, the reset mechanism includes: a slide rod fixedly installed on the inner wall of the top of the fermenter, a slide frame slidably installed on the slide rod, and the slide frame and the material turning frame being fixedly connected; and two springs sleeved on the slide rod, with the two springs located on both sides of the slide frame respectively.

[0008] Preferably, the fermenter is equipped with an aerator for introducing air into the fermenter, and an air vent pipe is fixedly installed on the fermenter, the air vent pipe being connected to the aerator.

[0009] Preferably, a feed pipe is fixedly installed on the fermentation tank, and multiple feeding pumps are fixedly installed on the fermentation tank. Each of the multiple feeding pumps is connected to a feeding pipe at its outlet end, and the multiple feeding pipes are connected to the feed pipe. The multiple feeding pumps are used to add defoamer and acid / alkali solutions to the fermentation tank, respectively.

[0010] Preferably, the fermenter is provided with a rinsing mechanism for rinsing the inside of the fermenter. The rinsing mechanism includes: a rinsing pipe rotatably mounted on the fermenter, the rinsing pipe having multiple rinsing heads and a flexible hose connected to the rinsing pipe; a connecting pipe fixedly mounted on the fermenter, the connecting pipe being connected to the flexible hose; and a second servo motor fixedly mounted on one side of the outer wall of the fermenter, the output shaft of the second servo motor being connected to one end of the rinsing pipe via a coupling.

[0011] Preferably, the fermenter is provided with a protective mechanism for protecting the rinsing head. The protective mechanism includes: a connecting shaft rotatably mounted on the fermenter, on which a protective plate for protecting the rinsing head is fixedly mounted; and a third servo motor fixedly mounted on one side of the outer wall of the fermenter, the output shaft of which is connected to one end of the connecting shaft via a coupling.

[0012] Preferably, a guide pipe is provided in the mounting cavity of the fermenter, and a sampling tube for sampling Armillaria mellea in the fermenter is fixedly installed at the bottom of the fermenter. Two placement shafts are symmetrically mounted on the sampling tube via a damping shaft. Each of the two placement shafts is fixedly fitted with a stop block, which is adapted to the inner wall of the sampling tube. A storage tube is connected to the sampling tube for storing the extracted Armillaria mellea samples.

A controller activates a first servo motor, which drives a stirring rack and a dispersing plate at the bottom of the stirring rack to rotate. The stirring rack and dispersing plate horizontally stir the Armillaria mellea, nutrient solution, and oxygen. Simultaneously, the rotation of the stirring rack activates a turning mechanism, which moves the turning rack vertically to vertically stir and turn the Armillaria mellea, nutrient solution, and oxygen within the fermentation tank. This allows for different forms of mixing and stirring of the Armillaria mellea, nutrient solution, and oxygen, ensuring sufficient contact between the Armillaria mellea and the nutrient solution, while simultaneously distributing oxygen evenly within the fermentation tank. This guarantees that the mycelium receives sufficient oxygen, preventing the inhibition of mycelial cell respiration and energy synthesis due to oxygen deficiency, thereby improving the overall fermentation effect of Armillaria mellea.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a fermentation apparatus for Armillaria mellea, such as... Figure 1-10 As shown, the Armillaria mellea fermentation device includes: a fermentation tank 1 for fermenting Armillaria mellea, a stirring rack 2 rotatably installed inside the fermentation tank 1 for horizontally stirring the Armillaria mellea, nutrient solution, and oxygen inside the fermentation tank 1; a first servo motor 3 fixedly installed on the fermentation tank 1, the output shaft of the first servo motor 3 being connected to the top of the stirring rack 2 via a coupling; a material turning rack 4 disposed inside the fermentation tank 1; and a material turning mechanism assembled between the fermentation tank 1 and the stirring rack 2 for driving the material turning rack 4 to move up and down and vertically stirring and turning the Armillaria mellea, nutrient solution, and oxygen inside the fermentation tank 1.

[0021] In this embodiment, a SIMATIC S7-1500 controller is installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be elaborated here. During the fermentation of *Armillaria mellea*, *Armillaria mellea*, nutrient solution, and corresponding additives are added to the fermentation tank 1, and air is simultaneously introduced. The oxygen in the air comes into contact with the *Armillaria mellea*. The controller starts the first servo motor 3, which drives the stirring rack 2 and the dispersing plate 12 at the bottom of the stirring rack 2 to rotate. The stirring rack 2 and the dispersing plate 12 can disperse the *Armillaria mellea*, nutrient solution, and oxygen. The horizontal stirring, combined with the rotation of the stirring rack 2, activates the material turning mechanism. This mechanism drives the material turning rack 4 to move up and down, vertically stirring and turning the Armillaria mellea, nutrient solution, and oxygen in the fermentation tank 1. This allows for different forms of mixing and stirring of the Armillaria mellea, nutrient solution, and oxygen, ensuring full contact between the Armillaria mellea and the nutrient solution, while also ensuring even distribution of oxygen within the fermentation tank 1. This guarantees that the mycelium receives sufficient oxygen, preventing the inhibition of mycelial cell respiration and energy synthesis due to oxygen deficiency, thereby improving the overall fermentation effect of Armillaria mellea.

[0022] In a further preferred embodiment of the present invention, the turning mechanism includes: a mounting shell 5 fixedly installed on the inner wall of the top of the fermentation tank 1, the mounting shell 5 being rotatably connected to the stirring frame 2; two mounting shafts 6 rotatably installed on the mounting shell 5; three bevel gears 7 respectively fixedly sleeved on the stirring frame 2 and the two mounting shafts 6, and the two bevel gears 7 respectively fixedly sleeved on the two mounting shafts 6 meshing with the bevel gear 7 fixedly sleeved on the stirring frame 2; two cams 8 respectively fixedly sleeved on the two mounting shafts 6, the two cams 8 being used to squeeze the tops of the two turning frames 4; and a reset mechanism assembled on the fermentation tank 1 and the turning frames 4, the turning frames 4 being reset after being squeezed by the reset mechanism.

[0023] In this embodiment, when the first servo motor 3 drives the stirring rack 2 to rotate for horizontal stirring, the bevel gear 7 on the stirring rack 2 will drive the bevel gear 7 on the two mounting shafts 6 that mesh with it to rotate, thereby causing the two mounting shafts 6 to rotate synchronously. Two cams 8 are fixedly sleeved on the two mounting shafts 6 respectively. As the mounting shafts 6 rotate, the two cams 8 will squeeze the tops of the two turning racks 4 respectively. When the cams 8 squeeze the turning racks 4 and make them move downward, the squeezed turning racks 4 can be reset under the action of the reset mechanism. In this way, the turning racks 4 realize the up and down movement, and vertically stir and turn the Armillaria mellea, nutrient solution and oxygen in the fermentation tank 1. In this way, it can cooperate with the stirring rack 2 to mix and stir the Armillaria mellea, nutrient solution and oxygen in different forms, so that the Armillaria mellea and nutrient solution can fully contact each other, and at the same time, the oxygen can be evenly distributed in the fermentation tank 1, ensuring that the mycelium can obtain sufficient oxygen, avoiding the inhibition of mycelial cell respiration and energy synthesis due to hypoxia, thereby improving the overall fermentation effect of Armillaria mellea.

[0024] In a further preferred embodiment of the present invention, the reset mechanism includes: a slide rod 9 fixedly installed on the inner wall of the top of the fermentation tank 1, a slide frame 10 slidably installed on the slide rod 9, the slide frame 10 and the turning frame 4 being fixedly connected; and two springs 11 sleeved on the slide rod 9, the two springs 11 being located on both sides of the slide frame 10 respectively.

[0025] In this embodiment, when the cam 8 presses the turning frame 4 to move downward, the slide 10 slides downward on the slide rod 9. At this time, the spring 11 located below the slide 10 is compressed. When the cam 8 rotates through a certain angle and stops pressing the turning frame 4, the compressed spring 11 will extend upward due to its own elastic potential energy, pushing the slide 10 to slide upward on the slide rod 9, thereby driving the turning frame 4 to reset upward. This process is repeated, and the turning frame 4 moves up and down to vertically stir and turn the Armillaria mellea, nutrient solution and oxygen in the fermenter 1.

[0026] In a further preferred embodiment of the present invention, an aerator 14 for introducing air into the fermentation tank 1 is provided inside the fermentation tank 1, and an air vent pipe 13 is fixedly installed on the fermentation tank 1, the air vent pipe 13 and the aerator 14 are connected.

[0027] In this embodiment, the vent pipe 13 is connected to the corresponding air compressor. The air compressor provides sterile compressed air, which is sent to the aerator 14 through the vent pipe 13. The aerator 14 then evenly disperses the sterile air into the fermenter 1 in the culture medium in the form of tiny bubbles, so that the oxygen in the air can come into contact with the Armillaria mellea. At the same time, the dispersing plate 12 can disperse the air discharged from the aerator 14, thereby making the air better distributed.

[0028] In a further preferred embodiment of the present invention, a feed pipe 101 is fixedly installed on the fermentation tank 1, and a plurality of feeding pumps 15 are fixedly installed on the fermentation tank 1. Each of the feeding pumps 15 is connected to a feeding pipe 16 at its discharge end, and the feeding pipes 16 are connected to the feed pipe 101. The feeding pumps 15 are respectively used to add defoamer and acid / alkali solution to the fermentation tank 1.

[0029] In this embodiment, the feed ends of multiple feed pumps 15 are respectively connected to the corresponding defoamer storage tank, acid solution storage tank, and alkaline solution storage tank. Each feed pipe 16 is equipped with a control valve, which controls the feed pipe 16. When a specific feed pipe 16 is needed, the control valve on that pipe is opened. When excessive foam is generated in the fermenter 1, the defoamer can be accurately added to the fermenter 1 via the feed pump 15 through the feed pipe 16 and feed pipe 101 to quickly eliminate the foam. When the pH of the fermentation system deviates from the suitable range, other feed pumps 15 are used to add acid and alkaline solutions to the fermenter 1 through the same path to adjust the pH value in a timely manner, creating a favorable acid-base environment for mycelial growth and maintaining the optimal pH environment for Armillaria mellea growth. Simultaneously, the fermenter 1 is equipped with an InPro 3250i pH sensor, which monitors the pH within the fermenter 1.

[0030] In a further preferred embodiment of the present invention, the fermenter 1 is provided with a rinsing mechanism for rinsing the interior of the fermenter 1. The rinsing mechanism includes: a rinsing pipe 17 rotatably mounted on the fermenter 1, the rinsing pipe 17 being provided with a plurality of rinsing heads 18, and a hose 19 connected to the rinsing pipe 17; a connecting pipe 20 fixedly mounted on the fermenter 1, the connecting pipe 20 and the hose 19 being connected in communication; and a second servo motor 21 fixedly mounted on one side of the outer wall of the fermenter 1, the output shaft of the second servo motor 21 being connected to one end of the rinsing pipe 17 via a coupling.

[0031] In this embodiment, after fermentation is completed, when it is necessary to clean the fermentation tank 1, the connecting pipe 20 and the corresponding water pump are connected, and a control valve is provided on the connecting pipe 20. When rinsing is required, the control valve on the connecting pipe 20 is opened, and the cleaning water enters the rinsing pipe 17 through the connecting pipe 20 and the hose 19, and then is sprayed into the fermentation tank 1 through the rinsing head 18. During cleaning, the second servo motor 21 is started by the controller to perform certain forward and reverse rotation, thereby driving the rinsing pipe 17 to rotate, and then causing the rinsing head 18 to rotate back and forth to perform all-round dynamic rinsing of the fermentation tank 1. Compared with static rinsing, dynamic rinsing can more thoroughly remove the residual materials in the fermentation tank 1.

[0032] In a further preferred embodiment of the present invention, the fermentation tank 1 is provided with a protective mechanism for protecting the rinsing head 18. The protective mechanism includes: a connecting shaft 22 rotatably mounted on the fermentation tank 1, a protective plate 23 for protecting the rinsing head 18 fixedly mounted on the connecting shaft 22; and a third servo motor 24 fixedly mounted on one side of the outer wall of the fermentation tank 1, the output shaft of the third servo motor 24 being connected to one end of the connecting shaft 22 via a coupling.

[0033] In this embodiment, during the fermentation process, the protective plate 23 is positioned to cover the rinsing head 18, providing reliable protection for the rinsing head 18 and preventing the rinsing head 18 from splashing onto the material in the fermentation tank 1 and causing blockage. When rinsing is required, the third servo motor 24 is started to drive the connecting shaft 22 to rotate, moving the protective plate 23 away so that the rinsing head 18 can spray water normally for rinsing.

[0034] In a further preferred embodiment of the present invention, a guide pipe 26 is provided in the mounting cavity 25 of the fermenter 1, and a sampling tube 27 for sampling Armillaria mellea in the fermenter 1 is fixedly installed at the bottom of the fermenter 1. Two placement shafts 28 are symmetrically mounted on the sampling tube 27 via a damping shaft. Each of the two placement shafts 28 is fixedly fitted with a stop block 29, which is adapted to the inner wall of the sampling tube 27. A storage tube 30 is connected to the sampling tube 27 for storing the extracted Armillaria mellea samples. A steam pipe 31 is connected to the storage tube 30 for introducing steam into the storage tube 30. An exhaust pipe 32 is connected to the storage tube 30 for discharging the steam introduced into the storage tube 30.

[0035] In this embodiment, during the stirring fermentation process, water at a certain temperature is introduced into the guide pipe 26 to control the temperature inside the fermentation tank 1, thereby fermenting Armillaria mellea. The fermentation tank 1 is equipped with a TMT162 temperature sensor to monitor the temperature inside. Simultaneously, in the non-sampling state, the two baffles 29 are tightly closed, sealing the sampling tube 27 and effectively preventing external air and bacteria from entering the fermentation tank 1, maintaining a sterile fermentation environment. When sampling is required, the placement shaft 28 above the sampling tube 27 is rotated to rotate the baffle 29 on it. At this time, part of the Armillaria mellea solution in the fermentation tank 1 enters the storage tube 30. Then, the placement shaft 28 above the sampling tube 27 is rotated in the opposite direction to rotate the baffle 29 back to its original position. Then, the placement shaft 28 below the sampling tube 27 is rotated to drive the stop block 29 on it to rotate, thereby taking out the sample from the storage tube 30. After sampling is completed, the placement shaft 28 below the sampling tube 27 is rotated in the opposite direction to drive the stop block 29 on it to rotate in the opposite direction to reset. Then, the steam pipe 31 and the corresponding steam supply pipe are connected, and the control valve on the steam pipe 31 is opened. The steam pipe 31 introduces steam into the storage tube 30 to sterilize the storage tube 30, ensuring that there are no bacteria residues in the storage tube 30, avoiding sample contamination during storage, ensuring the accuracy and reliability of the sample taken, and reducing the possibility of bacteria entering the fermenter 1 through the sampling tube 27. At the same time, the control valve on the exhaust pipe 32 is opened, and the exhaust pipe 32 discharges the steam introduced into the storage tube 30.

[0036] In a further preferred embodiment of the present invention, a transparent observation port 33 is provided on the fermentation tank 1 for viewing the inside of the fermentation tank 1. A round rod 34 is rotatably mounted on the fermentation tank 1 via a damping shaft. A connecting block 35 is fixedly mounted on the round rod 34. A shielding plate 36 is fixedly mounted on the connecting block 35 for protecting the transparent observation port 33. A limiting block 37 is fixedly mounted on the fermentation tank 1 for limiting the rotational position of the shielding plate 36.

[0037] In this embodiment, when it is necessary to observe the situation inside the fermentation tank 1, the shield 36 is rotated to move away from the transparent observation port 33, and the inside of the fermentation tank 1 is viewed through the transparent observation port 33. After the observation is completed, the shield 36 is rotated in the opposite direction to return to the position covering the transparent observation port 33. The limiting block 37 can ensure that the shield 36 is accurately in place, so as to achieve reliable protection of the transparent observation port 33.

[0038] This invention also proposes a method for fermenting Armillaria mellea, comprising: S1, placing Armillaria mellea mycelium and nutrient solution into a fermentation tank 1, and simultaneously introducing oxygen; S2, using a first servo motor 3 to drive a stirring rack 2 to rotate and horizontally stir the Armillaria mellea mycelium, nutrient solution, and oxygen in the fermentation tank 1, and using a turning rack 4 to vertically stir the Armillaria mellea mycelium, nutrient solution, and oxygen in the fermentation tank 1; S3, during the stirring and fermentation process, introducing water at a certain temperature into a guide pipe 26 to control the temperature inside the fermentation tank 1, thereby fermenting Armillaria mellea.

[0039] In summary, compared with related technologies, this device can ferment Armillaria mellea and mix and stir Armillaria mellea, nutrient solution and oxygen in different ways to ensure uniform oxygen distribution, guarantee that the mycelium can obtain sufficient oxygen, avoid the inhibition of mycelial cell respiration and energy synthesis due to hypoxia, thereby improving the overall fermentation effect of Armillaria mellea.
