Description

An apparatus and method for directly fermenting fresh Polygonatum using edible fungi. Technical Field

[0001] This invention relates to the field of microbial fermentation, and in particular to an apparatus and method for directly fermenting fresh Polygonatum using edible fungi. Background Technology

[0002] Polygonatum, a traditional Chinese medicine, has the effects of tonifying qi and nourishing yin, strengthening the spleen and moistening the lungs, and is widely used in the field of traditional Chinese medicine. Fresh Polygonatum is rich in various bioactive components and has high medicinal and health-promoting value, but direct use has problems such as low absorption rate of effective components and unpleasant taste. Fermentation can improve its properties and enhance its medicinal value.

[0003] In the existing fermentation process of Polygonatum, fresh Polygonatum is not suitable for direct consumption due to its irritating and numbing effect on the tongue. Therefore, Polygonatum used for food and medicine needs to be processed before use. Traditional processing methods mainly involve steaming and stewing, and sometimes auxiliary materials (such as wine, black beans, and honey) are added to improve quality and efficiency. However, traditional processing methods are cumbersome, time-consuming, labor-intensive, and costly.

[0004] Furthermore, traditional fermentation equipment is limited in function, mostly providing only a basic fermentation environment and failing to effectively meet the specific needs of solid-state fermentation. During solid-state fermentation, mycelial growth requires sufficient oxygen, but traditional equipment struggles to guarantee adequate aeration of the fermenting material, often relying solely on top ventilation. This can easily lead to incomplete fermentation, affecting fermentation efficiency and effectiveness. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an apparatus and method for directly fermenting fresh Polygonatum using edible fungi. This fermentation method is simpler and safer than existing preparation methods, has a wide range of raw material sources, and the fermented product has a good anti-tumor effect. In addition, the solid fermented product can be shaken and aerated in the fermentation apparatus to promote aerobic respiration during solid fermentation, thereby improving fermentation efficiency and effect.

[0009] Preferably, the air intake mechanism includes an air-accumulating piston cylinder fixedly connected to the left side of the processing chamber. A transparent piston cylinder is fixedly connected between the inner walls of the left and right sides of the sterilization chamber. A first piston plate that can slide left and right is provided inside the transparent piston cylinder. The right side of the first piston plate is elastically connected to the right side wall of the transparent piston cylinder through an air-accumulating spring. An exhaust pipe is connected to the left side space of the transparent piston cylinder. The other end of the exhaust pipe is connected to a connecting hose. The left side space of the air-accumulating piston cylinder is connected to the outside through a first one-way channel. The left side space of the air-accumulating piston cylinder is connected to the left side space of the transparent piston cylinder through a second one-way channel. A filter is installed at the other end of the first one-way channel. A UV lamp plate is installed at the bottom of the sterilization chamber. An exhaust port is opened at the top of the processing chamber. Solenoid valves are installed inside both the exhaust port and the exhaust pipe.

[0010] Preferably, the flow direction of the one-way valve inside the first one-way channel is one-way from the outside into the gas storage piston cylinder, and the flow direction of the one-way valve inside the second one-way channel is one-way from the gas storage piston cylinder into the space on the left side of the transparent piston cylinder.

[0011] Preferably, the shaking mechanism includes a drive motor installed inside the processing cavity. The output shaft of the drive motor is fixedly connected to a drive disk. A connecting rod is rotatably connected to the lower eccentric part of the drive disk. The other end of the connecting rod is rotatably connected to a support plate. The lower end of the shaking plate is elastically connected to the inner bottom of the second rectangular groove through multiple third springs. An extension plate is fixedly connected to the left side of the shaking plate. An arc-shaped abutment is fixedly connected to the lower end of the extension plate. An arc-shaped protrusion that cooperates with the arc-shaped abutment is provided at the bottom of the left side space of the processing cavity.

[0012] Preferably, an abutment plate is fixedly connected to the upper end of the left side portion of the extension plate, and a second piston plate that can slide left and right is provided inside the gas storage piston cylinder. The left side of the second piston plate is connected to the elastic block of the left side wall of the gas storage piston cylinder through a second spring, and an abutment column is fixedly connected to the right side of the second piston plate. The right side of the abutment column contacts the abutment plate and is slidably connected.

[0013] This invention also discloses a method for directly fermenting fresh Polygonatum using edible fungi. The method employs the aforementioned fermentation apparatus and includes the following steps: Step 1: Fresh Polygonatum is cleaned by removing root impurities, washed with water, and drained. It is then sliced ​​using a slicer to a thickness of 0.5 cm and dried in a 60℃ electric heating oven. After drying, it is pulverized using a pulverizer and sieved to obtain Polygonatum powder. Step 2: Cordyceps militaris mycelium is inoculated onto potato dextrose agar medium and cultured at 28℃ for 7-10 days for fermentation. Step 3: Polygonatum powder is soaked in water for 30 minutes, sterilized at 121℃ for 20 minutes, inoculated with Cordyceps militaris mycelium, and placed on a columnar carrier box in the processing chamber for fermentation. Step 4: The fermented Polygonatum is rapidly frozen at -80℃ and then freeze-dried in a vacuum freeze dryer. After drying, it is pulverized to obtain solid-state fermented freeze-dried Polygonatum powder.

[0014] Compared with existing technologies, the advantages of this invention are as follows: 1. This invention directly ferments Polygonatum sibiricum, eliminating many complex and time-consuming processes compared to traditional processing methods. During fermentation, the solid matrix is ​​loosened by shaking the columnar support box, increasing porosity. Combined with the gas circulation system, sufficient oxygen is provided for the fermentation of Polygonatum sibiricum, promoting its aerobic respiration and effectively improving fermentation efficiency. This allows for complete fermentation of Polygonatum sibiricum in a shorter time, saving time and costs.

[0015] 2. The columnar support box vibrates vertically and horizontally, loosening the solid matrix and significantly increasing porosity. The gas circulation system evenly delivers sterilized gas into the tank, providing ample oxygen for the fermentation of Polygonatum odoratum. This significantly improves ventilation, helping to remove carbon dioxide generated by heat buildup and respiration, creating a favorable gaseous environment for fermentation.

[0016] 3. The heat exchanger installed at the rear of the chamber extends its inlet and outlet to both sides of the processing chamber. Temperature sensors provide real-time feedback on the temperature inside the processing chamber, allowing the control system to precisely adjust the heat exchanger's operation, maintaining a constant temperature within the chamber. This provides a suitable temperature environment for the fermentation of fresh Polygonatum sibiricum, ensuring stable fermentation and improving fermentation quality. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Referring to Figures 1-8, an apparatus for directly fermenting fresh Polygonatum using edible fungi includes a housing 1. The housing 1 contains a processing chamber 7 and a sterilization chamber 9. A sealing door 2 is installed on the front of the processing chamber 7 for easy material handling. A control switch 3 and a display panel 4 are installed on the front of the housing 1 for easy operation and monitoring of fermentation parameters. A heat exchanger 6 is installed on the rear of the housing 1, with its inlet and outlet extending to the left and right sides of the processing chamber 7, respectively. A temperature sensor 8, which works in conjunction with the heat exchanger 6, is installed on the right side wall of the processing chamber 7. This sensor can monitor and adjust the temperature inside the processing chamber 7 in real time, maintaining a constant internal temperature and providing a suitable temperature environment for the fermentation of fresh Polygonatum using edible fungi.

[0021] The system also includes a placement mechanism, which comprises a first rectangular groove 18 formed at the bottom of the processing cavity 7. A slidable support plate 19 is disposed inside the first rectangular groove 18. Guide grooves can also be provided on the front and rear sides of the first rectangular groove 18. Guide strips are fixed on the front and rear sides of the support plate 19 to ensure actual sliding effect. A second rectangular groove is formed at the upper end of the support plate 19. A vibrating plate 28 is disposed inside the second rectangular groove. Multiple columnar grooves 32 are formed at the upper end of the vibrating plate 28. Each columnar groove 32 contains a columnar support box 33. Each columnar support box 33 has an external thread layer 36 on its outer side. Each columnar groove 32 has an internal thread layer 37 that mates with the external thread layer 36 on its inner side. Each columnar carrier 33 has a rubber sealing ring at its lower end to improve sealing. Each columnar carrier 33 consists of an upper groove and a bottom cavity. Each cavity is connected to the corresponding groove through multiple air holes 34. Each cavity has a connecting interface at its inner bottom. Each columnar groove 32 has a connecting port 35 at its inner bottom. The other end of each connecting port 35 is connected to a horizontal channel 38. The other end of the horizontal channel 38 is connected to a connecting hose 39. Subsequently, when Polygonatum is placed in the groove of the columnar carrier 33, sterile gas can enter the cavity through the connecting hose 39, the horizontal channel 38, the connecting port 35, and the connecting interface, and then enter the groove evenly through the air holes 34, providing sufficient oxygen for Polygonatum fermentation, promoting aerobic respiration, and improving fermentation efficiency.

[0022] The connecting hose 39 supplies sterile gas through an air intake mechanism, which includes a gas-accumulating piston cylinder 21 fixedly connected to the left side of the processing chamber 7. A transparent piston cylinder 10 is fixedly connected between the inner walls of the left and right sides of the sterilization chamber 9. A first piston plate 13, which can slide left and right, is installed inside the transparent piston cylinder 10. The right side of the transparent piston cylinder 10 is connected to the outside through an adjustment hole. The right side of the first piston plate 13 is elastically connected to the right side wall of the transparent piston cylinder 10 through a gas-accumulating spring 11. An exhaust pipe 14 is connected to the left side of the transparent piston cylinder 10, and the other end of the exhaust pipe 14 is connected to the connecting hose 39. The left side of the gas-accumulating piston cylinder 21 is connected to the outside through a first one-way channel 25, and the left side of the gas-accumulating piston cylinder 21 is connected to the outside through a second one-way channel 25. One-way channel 27 is connected to the left space of transparent piston cylinder 10. A filter 26 is installed at the other end of the first one-way channel 25 to filter impurities in the incoming gas. The left space is also connected to the left space of transparent piston cylinder 10 through the second one-way channel 27. A UV lamp plate 12 is installed at the bottom of the sterilization chamber 9. An exhaust port 5 is opened at the top of the processing chamber 7. Solenoid valves are installed inside the exhaust port 5 and the exhaust pipe 14. After each start-up and power-off of the drive motor 15, both solenoid valves will be energized for a period of time and then closed. The flow direction of the one-way valve inside the first one-way channel 25 is one-way from the outside into the gas storage piston cylinder 21. The flow direction of the one-way valve inside the second one-way channel 27 is one-way from the gas storage piston cylinder 21 into the left space of transparent piston cylinder 10.

[0023] The system also includes a shaking mechanism to improve the uniformity of gas supply from the intake mechanism. The shaking mechanism includes a drive motor 15 installed inside the processing chamber 7, electrically connected to the UV lamp plate 12. The output shaft of the drive motor 15 is fixedly connected to a drive disk 16. A connecting rod 17 is rotatably connected to the lower eccentric end of the drive disk 16. The other end of the connecting rod 17 is rotatably connected to a support plate 19. The lower end of the shaking plate 28 is elastically connected to the inner bottom of the second rectangular groove via multiple third springs 31. An extension plate 29 is fixedly connected to the left side of the shaking plate 28, and an arc-shaped abutment 40 is fixedly connected to the lower end of the extension plate 29. An arc-shaped protrusion 22, which cooperates with the arc-shaped abutment 40, is provided at the bottom of the left side space of the processing chamber 7. An abutment plate 30 is fixedly connected to the upper end of the left side portion of the extension plate 29. A sliding piston cylinder 21 is provided inside the cylinder. The second piston plate 23 is movable. The left side of the second piston plate 23 is connected to the elastic block on the left side wall of the gas storage piston cylinder 21 via the second spring 24. The right side of the second piston plate 23 is fixedly connected to the abutment column 20. The right side of the abutment column 20 contacts the abutment plate 30 and is slidably connected. After the drive motor 15 is started, it drives the drive disk 16 to rotate. The bearing plate 19 slides left and right through the connecting rod 17. At the same time, the arc-shaped abutment strip 40 and the arc-shaped protrusion strip 22 cooperate to make the shaking plate 28 shake up and down. The abutment plate 30 pushes the abutment column 20 to realize the shaking of the columnar bearing box 33 in the up and down and left and right directions. This shaking can loosen the solid matrix, increase the porosity, and prevent caking. The second piston plate 23 slides left and right in the gas storage piston cylinder 21 and can inject gas into the space on the left side of the transparent piston cylinder 10. After being sterilized by the ultraviolet lamp plate 12, it is injected into the connecting hose 39.

[0024] The working principle of this invention is as follows: Take an appropriate amount of Polygonatum powder, add water and soak for 30 minutes. Then, sterilize the soaked Polygonatum at 121℃ for 20 minutes. After sterilization, inoculate with Cordyceps militaris mycelium, lay a breathable cloth at the bottom of the columnar support box 33, and then put in the fermentation substrate. Place the pre-treated Polygonatum into the columnar support box 33. Since each columnar support box 33 has an external thread layer 36 on its outer side and each columnar groove 32 has an internal thread layer 37 that mates with the external thread layer 36 on its inner side, the columnar support box 33 can be screwed into the columnar groove 32. The rubber sealing ring at the lower end of each columnar support box 33 can improve the sealing performance. Then, close the sealing door 2 at the front of the processing chamber 7. Start the drive motor 15 periodically. The output shaft of the drive motor 15 drives the drive disk 16 to rotate. The drive disk 16 causes the support plate 19 to slide left and right in the first rectangular groove 18 through the connecting rod 17. Meanwhile, the lower end of the shaking plate 28 is elastically connected to the bottom of the second rectangular groove through multiple third springs 31. The lower end of the extension plate 29 on the left side of the shaking plate 28 is fixedly connected to an arc-shaped abutment 40. An arc-shaped protrusion 22 that cooperates with the arc-shaped abutment 40 is provided at the bottom of the space on the left side of the processing cavity 7. During the left and right sliding of the bearing plate 19, the arc-shaped abutment 40 and the arc-shaped protrusion 22 cooperate to make the shaking plate 28 shake up and down. The left and right sliding of the bearing plate 19 and the up and down shaking of the shaking plate 28 can make the columnar bearing box 33 shake in the up and down and left and right directions, loosen the solid matrix, increase the porosity, and prevent the plate from caking and clumping.

[0025] The abutment plate 30, fixedly connected to the upper left side of the extension plate 29, also moves with the left and right movement of the vibrating plate 28. The abutment column 20 drives the second piston plate 23 inside the gas storage piston cylinder 21 to slide left and right. When the second piston plate 23 slides to the right, a negative pressure is generated in the space on the left side of the gas storage piston cylinder 21, and the outside gas enters the gas storage piston cylinder 21 through the first one-way channel 25. When the second piston plate 23 slides to the left, the gas in the gas storage piston cylinder 21 enters the space on the left side of the transparent piston cylinder 10 through the second one-way channel 27. The gas entering the space on the left side of the transparent piston cylinder 10 is sterilized by the ultraviolet lamp plate 12 installed at the bottom of the sterilization chamber 9 and is accumulated. At this time, because the solenoid valve is closed, the accumulated gas will push the first piston plate 13 to the right and compress the gas storage spring 14. When the drive motor 15 is turned off, the gas is released and enters the connecting hose 39 through the exhaust pipe 14, and then through the horizontal The channel 38, the connecting port 35, and the interface enter the cavity of the columnar support box 33, and finally enter the tank evenly through the air hole 34, providing sufficient oxygen for the fermentation of Polygonatum, promoting aerobic respiration, and improving fermentation efficiency. Since the processed Polygonatum substrate is loose and the porosity is increased at this time, the ventilation effect is better in this state, and it helps to remove the carbon dioxide generated by heat accumulation and respiration. The heat exchanger 6 installed on the rear side of the box 1 has its air inlet and air outlet extending to the left and right sides of the processing chamber 7, respectively. According to the temperature information fed back by the temperature sensor 8, the control system adjusts the operation of the heat exchanger 6 to achieve a constant internal temperature in the processing chamber 7, providing a suitable temperature environment for the fermentation of fresh Polygonatum by edible fungi.

[0026] Continue the above process until the Polygonatum sibiricum is fully fermented. Once fermentation is complete, open the sealed door 2 to remove it.

[0027] This invention also discloses a method for directly fermenting fresh Polygonatum using edible fungi. The method employs the aforementioned fermentation apparatus and includes the following steps: Step 1: Fresh Polygonatum is cleaned by removing root impurities, washed with water, and drained. It is then sliced ​​using a slicer to a thickness of 0.5 cm and dried in a 60℃ electric heating oven. After drying, it is pulverized using a pulverizer and sieved to obtain Polygonatum powder. Step 2: Cordyceps militaris mycelium is inoculated onto potato dextrose agar medium and cultured at 28℃ for 7-10 days for fermentation. Step 3: Polygonatum powder is soaked in water for 30 minutes, sterilized at 121℃ for 20 minutes, inoculated with Cordyceps militaris mycelium, and placed on a columnar carrier box 33 in the processing chamber 7 for fermentation. Step 4: The fermented Polygonatum is rapidly frozen at -80℃ and then freeze-dried in a vacuum freeze dryer. After drying, it is pulverized to obtain solid-state fermented freeze-dried Polygonatum powder.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
