Abstract
Description
Technical Field
[0001] This invention relates to the field of industrialized production technology of edible fungi, and in particular to an inoculation device and inoculation method suitable for integrated fermentation of edible fungi culture media. Background Technology
[0002] In industrialized production of edible fungi, inoculation is a crucial step, and the cleanliness, uniformity, and efficiency of the inoculation process directly affect mycelial growth and final yield.
[0003] In traditional straw mushroom production, manual inoculation is usually carried out on the surface of the substrate in the fruiting room after the fermentation material has been disinfected, sterilized, and cooled. This manual inoculation, carried out in the hot and humid environment of the fruiting room, is prone to problems such as high risk of contamination by miscellaneous bacteria, poor inoculation uniformity, high labor intensity, harsh working environment, and low production efficiency. If a three-stage fermentation substrate is used, how to achieve automated, clean, and efficient inoculation of the multi-layered substrate without opening the box or destroying the favorable internal fermentation environment has become a technical challenge.
[0004] Therefore, it is of great significance to design a mechanized inoculation device that can be integrated into a closed fermentation equipment and achieve precise positioning, automatic operation, and adaptability to multi-layer structures. Summary of the Invention
[0005] To address the shortcomings of the existing technologies, this invention provides an inoculation device suitable for integrated fermentation of edible fungi culture media, achieving a reasonable device structure design and enabling automated and precise inoculation during the fermentation process of straw mushrooms.
[0006] To achieve the above objectives, the present invention provides an inoculation device suitable for integrated fermentation of edible fungi culture media, which is installed at the top of a fermentation chamber containing the edible fungi culture media. The fermentation chamber contains a layered culture bed. The inoculation device includes:
[0007] Linear guide rails are fixed parallel to both sides of the top of the fermentation chamber.
[0008] An automatic inoculation unit is located at the top of the fermentation chamber and can move along the linear guide rail;
[0009] The automatic inoculation unit includes a lateral movement mechanism controlled by a split motor for lateral movement and vertical extension and retraction, a multi-stage telescopic rod, and an inoculation mechanism capable of omnidirectional rotation.
[0010] In some embodiments, the lateral movement mechanism includes:
[0011] A slider and guide rail drive motor, wherein the slider and the linear guide rail form a sliding pair, and the output shaft of the guide rail drive motor is connected to a gear;
[0012] A rack is fixedly installed along the length of the fermentation chamber.
[0013] The rack and the gear form a meshing transmission pair.
[0014] In some embodiments, the inoculation device further includes a telescopic rod fixing seat, the guide rail drive motor is mounted on the telescopic rod fixing seat, and the slider is fixed together with the telescopic rod fixing seat.
[0015] In some embodiments, the fixed end of the multi-stage telescopic rod is connected to the telescopic rod fixing seat, and a telescopic drive motor is installed on the side of the telescopic rod fixing seat.
[0016] In some embodiments, the end of the multi-stage telescopic rod is attached to the inoculation mechanism via a rotating wheel mechanism.
[0017] In some embodiments, the rotating mechanism is driven by a micro motor, which enables the inoculation mechanism to rotate 360 degrees.
[0018] In some embodiments, the inoculation device further includes a control system, which uses a PLC as a lower-level machine and is electrically connected to the control unit of the guide rail drive motor, the telescopic drive motor, the micro motor, and the inoculation mechanism.
[0019] In some embodiments, the multi-stage telescopic rod has four or more sections, and its maximum extension length ensures that the inoculation mechanism reaches the bottom layer of the tiered culture bed. In some embodiments, the inoculation mechanism is a solid particle inoculum dispensing device or a liquid inoculum spraying device.
[0020] The present invention also provides an inoculation method suitable for integrated fermentation of edible fungi culture media, which uses the inoculation device as described above, and the inoculation method includes the following steps:
[0021] After the culture medium in the fermentation chamber has cooled down during the pre-inoculation stage, the control system starts the guide rail drive motor. Through the meshing of gears and racks, the telescopic rod fixing seat, multi-stage telescopic rod, and inoculation mechanism move along the linear guide rail to the work position corresponding to the first layer of culture medium. Then, the telescopic drive motor drives the multi-stage telescopic rod to descend, while the rotating wheel mechanism adjusts the angle of the inoculation mechanism and starts the inoculation mechanism to complete the inoculation of this layer. Subsequently, the multi-stage telescopic rod retracts, and the control system controls the inoculation mechanism to move to the next work position, repeating the actions of descending, adjusting the angle, inoculating, and lifting, until all layers of the culture bed have been traversed.
[0022] Compared with the prior art, the present invention has the following advantages:
[0023] The inoculation device provided by this invention is a mechanized device for automated and precise inoculation in an integrated fermentation, sterilization and inoculation preparation box for edible fungi culture media. By combining a multi-degree-of-freedom robotic arm with intelligent control, it solves the problem of automatic inoculation of multi-layer materials in a confined space.
[0024] The inoculation device for integrated fermentation of edible fungi culture medium provided by the present invention uses a split motor to control the lateral movement and vertical extension and contraction, and is supplemented by an inoculation mechanism that can rotate in all directions, so as to realize the inoculation of multi-layer culture medium in a sealed box in a precise and automated manner without dead angles.
[0025] The inoculation device provided by this invention, suitable for integrated fermentation of edible fungi culture media, completes the inoculation operation entirely inside the fermentation chamber using a split-type motor, eliminating the risk of contamination by miscellaneous bacteria caused by traditional open inoculation or material transfer. The inoculation device is reliable in operation, highly automated, greatly reduces the labor intensity of the inoculation process, improves inoculation efficiency and uniformity, and ensures the consistency of product quality.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0044] See Figure 1-4 An embodiment of the present invention provides an inoculation device suitable for integrated fermentation of edible fungi culture medium. The device is installed on the top of the fermentation chamber 1 of the edible fungi culture medium. The fermentation chamber 1 contains a layered mushroom bed 2. The inoculation device includes: a linear guide rail 3, which is fixed parallel to both sides of the top of the fermentation chamber 1; and an automatic inoculation unit, which is located on the top of the fermentation chamber 1 and can move along the linear guide rail 3. The automatic inoculation unit includes a lateral movement mechanism controlled by a split motor for lateral movement and vertical extension and retraction, a multi-stage telescopic rod 4, and an inoculation mechanism 5 capable of omnidirectional rotation.
[0045] The lateral movement mechanism includes: a slider 6 and a guide rail drive motor 7. The slider 6 and the linear guide rail 3 form a sliding pair. The output shaft of the guide rail drive motor 7 is connected to a gear 8. A rack 9 is fixedly installed along the length of the fermentation chamber 1. The rack 9 and the gear 8 form a precise linear meshing transmission pair.
[0046] In this embodiment, the inoculation device further includes a telescopic rod fixing seat 10, the guide rail drive motor 7 is mounted on the telescopic rod fixing seat 10, and the slider 6 is fixed together with the telescopic rod fixing seat 10; the fixed end of the multi-stage telescopic rod 4 is connected to the telescopic rod fixing seat 10, and a telescopic drive motor 11 is mounted on the side of the telescopic rod fixing seat 10, which is driven by a lead screw mechanism to drive the multi-stage telescopic rod 4 to perform multi-stage telescopic extension and retraction.
[0047] In this embodiment, the end of the multi-stage telescopic rod 4 is mounted to the inoculation mechanism 5 via a rotating wheel mechanism 12. The rotating wheel mechanism 12 is driven by a micro motor, which enables the inoculation mechanism 5 to rotate 360 degrees.
[0048] The inoculation device in this embodiment also includes a control system. The control system uses a PLC as the lower-level machine and is electrically connected to the control unit of the guide rail drive motor 7, the telescopic drive motor 11, the micro motor, and the inoculation mechanism 5.
[0049] In this embodiment, the multi-stage telescopic rod 4 has four or more sections to provide sufficient working space to cover all material layers, and its maximum extension length can ensure that the inoculation mechanism 5 can reach the bottom layer of the layered substrate 2.
[0050] In this embodiment, the inoculation mechanism 5 is a bacterial seed dispersing device, which can be a solid particle bacterial seed dispersing device or a liquid bacterial seed spraying device, to adapt to solid particle bacterial seeds or liquid bacterial seeds.
[0051] Another embodiment of the present invention provides an inoculation method suitable for integrated fermentation of edible fungi culture media, which uses the inoculation device described in the foregoing embodiments, and the inoculation method includes the following steps:
[0052] Once the culture medium in fermentation chamber 1 has completed the secondary fermentation process and cooled to the pre-inoculation temperature (e.g., 35-38℃), the control system starts the guide rail drive motor 7. Through the meshing of gear 8 and rack 9, the telescopic rod fixing seat 10, multi-stage telescopic rod 4, and inoculation mechanism 5 move along the linear guide rail 3 to the work position corresponding to the first layer of culture medium. Then, the telescopic drive motor 11 drives the multi-stage telescopic rod 4 to descend, while the rotating wheel mechanism 12 adjusts the angle of the inoculation mechanism 5, and the inoculation mechanism 5 is started to complete the inoculation of this layer. After the inoculation of this layer is completed, the multi-stage telescopic rod 4 retracts, and the control system controls the inoculation mechanism 5 to move to the work position corresponding to the next layer of culture medium, repeating the actions of descending, adjusting the angle, inoculating, and lifting, until all layers of the culture bed 2 have been traversed, and all inoculation operations are completed. The inoculation method for integrated fermentation of edible fungi culture media provided by this invention, after the culture medium in the fermentation chamber has completed the cooling process during the pre-inoculation stage, initiates the inoculation process. A guide rail drive motor, through gear and rack engagement, drives a telescopic rod fixing seat, moving the entire inoculation unit along a linear guide rail to the target position. The telescopic drive motor lowers the telescopic rod, while a rotating wheel mechanism adjusts the inoculation angle, activating the inoculation mechanism to complete precise inoculation. The system then automatically moves to the next position until all material layers have been traversed. This invention uses the same precisely positioned inoculation mechanism to automatically inoculate each layer of culture medium after fermentation, achieving continuous operation from fermentation to inoculation within a closed space. This device significantly improves the automation and precision of the inoculation process, effectively eliminating the contamination risks and efficiency bottlenecks associated with manual inoculation or inoculation by turning the fermentation chamber over, and offers advantages such as precise control and ease of operation.
[0053] The inoculation device provided by this invention, suitable for integrated fermentation of edible fungi culture medium, belongs to the technical field of industrialized edible fungi production equipment. The device is installed inside the culture medium fermentation chamber. Through the combination of multi-degree-of-freedom mechanical transmission and intelligent control, it realizes automated, precise and clean inoculation operations in a closed fermentation environment, effectively solving the industry pain points in the inoculation process.
