Description

Technical Field

[0001] This invention relates to the field of culture medium processing technology, specifically to a device and method for preparing culture medium for Poria cocos strain. Background Technology

[0002] Poria cocos strains are specific strains used to cultivate Poria cocos, a fungus that parasitizes the roots of pine trees. It is widely used in traditional Chinese medicine and has effects such as promoting diuresis and removing dampness, strengthening the spleen and calming the mind. Poria cocos strains are selected and purified strains that can ensure the stable growth and medicinal quality of Poria cocos. They are often used in the production process of artificially cultivating Poria cocos to improve yield and quality.

[0003] Please refer to Chinese Invention Patent No. CN117441548B, which discloses a novel method and equipment for preparing a culture medium for Poria cocos. The preparation method of this invention includes the following steps: weighing each component of the culture medium; mixing each component; bagging the culture medium; inserting pine strips evenly at intervals into the culture bags; and sterilizing in a mechanical boiler-free sterilizer for 2 hours. This method can reduce the aging rate of mycelium and ensure that the aging rate of mycelium is uniform, avoiding gaps between the culture bags and pine stumps. Furthermore, the preparation equipment provided by this invention can complete the processing of the culture medium, prevent components from adhering to the stirring paddle, and evenly place the pine strips in the culture medium.

[0004] However, inserting the cut pine strips entirely into the olefin bag results in insufficient contact area between the pine strips and the culture medium, leading to uneven distribution of nutrients and poor uniformity in mycelial growth. In addition, inserting several whole pine strips into the olefin bag at the same time will occupy excessive space inside the bag, reducing the amount of culture medium and limiting the space for mycelial growth, thus affecting the growth and reproduction of the strain. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for preparing a culture medium for Poria cocos, which involves cutting pine strips into segments and distributing them evenly in layers within a polysaccharide bag, ensuring that the pine blocks are evenly distributed within the polysaccharide bag, while also not occupying too much space within the polysaccharide bag, thereby effectively solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A device for preparing a culture medium for Poria cocos includes a bagging cylinder, a sleeve bagging cylinder, a cutting cylinder, a dicing cylinder, and a dispensing mechanism. The sleeve bagging cylinder is fitted outside the bagging cylinder and can slide up and down for adjustment. The bottom of the bagging cylinder is located inside the sleeve bagging cylinder. The cutting cylinder is used to fix and open the culture bag. The cutting cylinder, dicing cylinder, and dispensing mechanism are arranged sequentially from top to bottom inside the bagging cylinder. The cutting cylinder is used to divide pine wood segments into several pine wood strips and transfer the pine wood strips to the cutting cylinder in sequence. The cutting cylinder is used to cut the pine wood strips into several pine wood blocks and transfer the pine wood blocks to the dispensing mechanism. The dispensing mechanism is used to evenly dispense the pine wood blocks into the culture bag.

[0008] By first cutting the pine wood ends into strips and then into blocks, and then evenly placing the pine wood blocks into the olefin bag, the contact area with each component of the culture medium is increased, ensuring a uniform distribution of nutrients within the bag. At the same time, the pine wood blocks are evenly distributed within the olefin bag, with gaps between the upper and lower layers and between the blocks in the same layer, which does not occupy too much space within the olefin bag, providing sufficient space for mycelial growth. This also ensures that the amount of each component in the bag is sufficient, which is conducive to the good growth and reproduction of the strain.

[0009] Preferably, a feed pipe is inserted into the side of the bagging cylinder, and the feed pipe extends downward to the bottom of the feeding mechanism for feeding the mixed culture medium in the mixing drum into the bagging cylinder, and then into the spore bag by the bagging cylinder. The end of the feed pipe located inside the bagging cylinder is partially vertical and is centrally located inside the bagging cylinder.

[0010] Preferably, four clamping cylinders are fixed in a circular array near the top of the outer wall of the bag cylinder. Each clamping cylinder has a connecting arm fixed to the end of its telescopic rod, and an arc-shaped clamping plate is fixed to the end of the connecting arm. The curvature of each arc-shaped clamping plate is adapted to the curvature of the outer edge of the bag cylinder.

[0011] Preferably, a pair of first electric cylinders are symmetrically fixed on the inner wall of the bagging cylinder, both of which extend vertically, and a pair of connecting blocks are symmetrically fixed on the inner wall of the bagging cylinder, with the ends of the telescopic rods of the two first electric cylinders respectively fixedly connected to the corresponding connecting blocks.

[0012] Preferably, the cutting cylinder is equipped with a cutting blade with a cross-section in the shape of a star. The cutting blade extends vertically inside the cutting cylinder. An L-shaped frame is fixed to the top of the bagging cylinder. A pressing cylinder is vertically fixed on the L-shaped frame. A pressure plate is fixed to the end of the extension rod of the pressing cylinder and directly above the cutting cylinder. A feeding notch is provided on one side above the cutting cylinder. The bottom of the feeding notch is higher than the top of the cutting blade.

[0013] Preferably, the cutting tool consists of eight cutting blades arranged in a circular array around the axis of the cutting cylinder. A temporary storage cavity is formed between two adjacent cutting blades for the individual temporary storage of pine strips. A shaft is rotatably mounted through the bottom of the cutting cylinder. The top of the shaft is fixed to the bottom of the cutting tool. A driven gear is fixed on the shaft. A first drive motor is fixed to the bottom of the cutting cylinder. A main gear that meshes with the driven gear is fixed on the output shaft of the first drive motor. The bottom of the cutting cylinder is provided with a discharge port through which pine strips pass. During the rotation of the cutting tool, the discharge port can only be aligned with one temporary storage cavity at a time.

[0014] Preferably, the cutting cylinder is arranged vertically and runs through the top and bottom. The top of the cutting cylinder corresponds to the outlet position. A drive cylinder is installed on one side of the bottom of the cutting cylinder. A cutting device is installed on the moving part of the drive cylinder. The drive cylinder is used to drive the cutting device to move below the cutting cylinder in a direction perpendicular to the cutting cylinder, so as to realize the cutting and retraction.

[0015] Preferably, the dispensing mechanism comprises a first guide chute, a second guide chute, a second electric cylinder, and a second drive motor. The second drive motor is mounted on the feed pipe via a mounting bracket. A vertically extending rotating shaft is fixed on the output shaft of the second drive motor, and the rotating shaft is coaxial with the bagging cylinder. The first guide chute is inclinedly mounted on the top of the rotating shaft, and the first guide chute is aligned with the lower end of the cutting cylinder. The second guide chute is slidably fitted below the first guide chute, and its inclination angle is the same as that of the first guide chute. The second electric cylinder is fixed to the side of the second guide chute, and the end of the telescopic rod of the second electric cylinder is fixedly connected to the side of the first guide chute. A vertically penetrating guide cylinder is provided at the lower end of the second guide chute, and the top of the guide cylinder receives the lower end of the second guide chute.

[0016] The present invention also provides a method for preparing a culture medium for Poria cocos strain, which specifically includes the following steps;

[0017] Step 1: Mix all components of the culture medium thoroughly.

[0018] Step 2: Place the cut pine wood blocks and the mixing material evenly into the olefin bag layer by layer;

[0019] Step 3: Sterilize using a mechanical boiler-free sterilizer for 2 hours.

[0020] The preparation equipment and method provided by this invention are used to prepare the culture medium for Poria cocos spawn. The pine wood ends are first cut into strips and then into blocks. The pine wood blocks are then evenly placed in the olefin bag to increase the contact area with each component of the culture medium. This ensures that the nutrient supply is evenly distributed in the bag. At the same time, the pine wood blocks are evenly distributed in the olefin bag, and there are gaps between the upper and lower layers and between the pine wood blocks in the same layer. This does not occupy too much space in the olefin bag, providing sufficient space for mycelial growth. It also ensures that the amount of each component in the bag is sufficient, which is conducive to the good growth and reproduction of the spawn.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0022] This invention involves first cutting the ends of pine wood into strips, then into blocks, and then evenly placing the pine wood blocks into the olefin culture bag. This increases the contact area with the various components of the culture medium, ensuring a uniform distribution of nutrients within the bag. Furthermore, the even distribution of pine wood blocks within the bag, with gaps between upper and lower layers and between blocks within the same layer, prevents the bag from taking up too much space, providing ample room for mycelial growth. It also ensures sufficient bag volume for each component, promoting healthy growth and reproduction of the fungus.

[0023] This invention uses a cutting tool to evenly cut pine segments. By coordinating the positions of the cutting cylinder and the first guide groove, it ensures that the length of each pine strip cut is approximately the same, thereby ensuring that the size of the pine blocks is basically consistent. This further improves the consistency of nutrient supply when the pine blocks are evenly distributed in the bag. In addition, the first guide groove can not only block and limit the pine strips to be cut, but also position the length of the pine strip cut, and is also used for the feeding of pine blocks, achieving multiple benefits in one go.

[0024] This invention places the cutting device inside the bagging cylinder. The pine wood chips produced by cutting pine strips fall directly into the bagging cylinder and are put into the bag together. They can be used as a supplement to the culture medium components. There is no need for additional collection and processing of pine wood chips, which avoids waste of pine wood chips. The structure layout is reasonable.

[0025] The cutting blade in this invention serves two purposes: cutting pine segments and temporarily storing pine strips. The blade also utilizes the storage cavity formed between adjacent cutting blades to store pine strips individually. By driving the cutting tool and each pine strip to rotate within the cutting cylinder, the storage cavity is aligned with the discharge outlet, allowing individual pine strips to fall into the cutting cylinder in an orderly manner for cutting, ensuring that the cutting process is well-organized.

[0026] The layer-by-layer feeding design of this invention avoids the situation where the bag opening is directly fitted onto the bottom of the bagging cylinder, which would cause excessive impact on the bag body due to the long material descent in the early stage of feeding, leading to bag detachment or damage. This allows the bag body to descend in an adaptive cycle following the layer-by-layer feeding rhythm, protecting the bag body while ensuring the stability of the feeding. Attached Figure Description

[0035] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0036] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0037] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0038] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0039] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0040] Please see Figures 1-7 This invention provides a device for preparing a culture medium for Poria cocos. The device includes a bagging cylinder 1, a covering cylinder 2, a cutting cylinder 3, a cutting cylinder 5, and a dispensing mechanism 6. The covering cylinder 2 is fitted outside the bagging cylinder 1 and can slide up and down for adjustment. The bottom of the bagging cylinder 1 is located inside the covering cylinder 2. The cutting cylinder 3 is used to fix and open the culture bag. The cutting cylinder 3, the cutting cylinder 5, and the dispensing mechanism 6 are arranged sequentially from top to bottom inside the bagging cylinder 1. The cutting cylinder 3 is used to divide pine wood segments into several pine wood strips and sequentially transfer the pine wood strips into the cutting cylinder 5. The cutting cylinder 5 is used to cut the pine wood strips into several pine wood blocks and transfer the pine wood blocks onto the dispensing mechanism 6. The dispensing mechanism 6 is used to evenly dispense the pine wood blocks into the culture bag.

[0041] By first cutting the pine wood ends into strips and then into blocks, and then evenly placing the pine wood blocks into the olefin bag, the contact area with each component of the culture medium is increased, ensuring a uniform distribution of nutrients within the bag. At the same time, the pine wood blocks are evenly distributed within the olefin bag, with gaps between the upper and lower layers and between the blocks in the same layer, which does not occupy too much space within the olefin bag, providing sufficient space for mycelial growth. This also ensures that the amount of each component in the bag is sufficient, which is conducive to the good growth and reproduction of the strain.

[0042] A feed pipe 9 is inserted into the side of the bagging cylinder 1, extending downwards to below the dispensing mechanism 6. This feed pipe 9 is used to dispense the mixed culture medium from the mixing drum into the bagging cylinder 1, and then into the mycelium bags from the bagging cylinder 1. The mixing drum uses existing technology and is not shown in the figure. Figure 2As shown, the feed pipe 9 is partially vertical at the end inside the bagging cylinder 1 and is centrally located inside the bagging cylinder 1. When the mixed material is fed into the bagging cylinder 1, it ensures that the mixed material falls vertically out of the center of the bagging cylinder 1. As a result, during bagging, the material accumulates as much as possible in the middle of the bag, and the mixed material rolls and spreads to the surrounding area, ensuring that it is distributed as evenly as possible inside the bag.

[0043] Please see Figure 1 and Figure 2 Four clamping cylinders 8 are fixed in a circular array near the top of the outer wall of the bagging cylinder 2. Each clamping cylinder 8 has a connecting arm 81 fixed to the end of its telescopic rod. Each connecting arm 81 has an arc-shaped clamping plate 82 fixed to the end. The curvature of each arc-shaped clamping plate 82 is adapted to the curvature of the outer edge of the bagging cylinder 1. The mycelium bag is placed on the outside of the bagging cylinder 2. The clamping cylinder 8 extends and works. Under the connecting action of the connecting arm 81, the arc-shaped clamping plate 82 is pushed to clamp the bag opening, thereby fixing the bag and ensuring the stability during bagging.

[0044] like Figure 2 As shown, a pair of first electric cylinders 11 are symmetrically fixed on the inner wall of the bagging cylinder 1. Both first electric cylinders 11 extend vertically. A pair of connecting blocks 12 are symmetrically fixed on the inner wall of the bag-covering cylinder 2. The ends of the telescopic rods of the two first electric cylinders 11 are respectively fixedly connected to the corresponding connecting blocks 12. By synchronously telescopically working, the two first electric cylinders 11 can drive the bag-covering cylinder 2 to move up and down along the surface of the bagging cylinder 1. During the initial bagging, the bag-covering cylinder 2 is adjusted upward to the limit position, driving the bottom of the bag to approach the bottom of the bagging cylinder 1. After the bottom layer of material is fed, the bag-covering cylinder 2 is then adjusted downward to drive the bag to move down, allowing the next layer of material to be fed. This process is repeated to allow for layer-by-layer feeding, ensuring the uniformity of the feeding. In addition, layer-by-layer feeding can avoid the situation where the bag opening is directly fitted onto the bottom of the bagging cylinder 1, which would cause excessive impact on the bag due to the long descent of the material in the initial feeding stage, leading to bag detachment or damage.

[0045] Please see Figures 3-6 The cutting cylinder 3 is equipped with a cutting blade 4 with a cross-section in the shape of a cross. The cutting blade 4 extends vertically inside the cutting cylinder 3. An L-shaped frame 72 is fixed at the top of the bagging cylinder 1. A pressing cylinder 7 is vertically fixed on the L-shaped frame 72. A pressure plate 71 is fixed at the end of the extension rod of the pressing cylinder 7 and directly above the cutting cylinder 3. When the pine wood segment is placed inside the cutting cylinder 3, the pressing cylinder 7 extends and pushes the pressure plate 71 down onto the pine wood segment. The cutting blade 4 can then cut the wood segment into multiple pine wood strips.

[0046] In addition, a feeding notch 301 is provided on one side above the cutting cylinder 3. The bottom of the feeding notch 301 is set higher than the top of the cutting blade 4. By setting the feeding notch 301, it is convenient to feed pine wood segments into the cutting cylinder 3 from the side, thereby avoiding the problem of ensuring sufficient space between the pressure plate 71 and the cutting cylinder 3 when feeding from the top, which helps to reduce the size of the equipment in the vertical direction.

[0047] Specifically, the cutting tool 4 consists of eight cutting blades 41 arranged in a circular array around the axis of the cutting cylinder 3. A temporary storage cavity 42 is formed between two adjacent cutting blades 41 for the individual storage of pine strips. After cutting, the pine strips can be stored individually in the temporary storage cavity 42, ensuring that the pine strips are arranged in an orderly manner. The cutting blades 41 serve as both the component for cutting pine wood and the partition for the individual storage of pine strips, achieving two goals at once.

[0048] A shaft 32 is rotatably mounted through the bottom of the cutting cylinder 3. The top of the shaft 32 is fixed to the bottom of the cutting blade 4. A driven gear 33 is fixed on the shaft 32. A first drive motor 34 is fixed to the bottom of the cutting cylinder 3. A main gear 35, which meshes with the driven gear 33, is fixed on the output shaft of the first drive motor 34. The bottom of the cutting cylinder 3 is provided with a discharge port 31 through which pine strips pass. During the rotation of the cutting blade 4, the discharge port 31 can only align with a temporary storage cavity 42 at a time. When the first drive motor 34 works, its output shaft can drive the main gear 35 to rotate. The rotating main gear 35 meshes with and drives the driven gear 33, which in turn drives the shaft 32 and the cutting blade 4 to rotate. This can drive each pine strip to rotate in the cutting cylinder 3. When the temporary storage cavity 42 rotates to align with the position of the discharge port 31, the pine strips in the temporary storage cavity 42 can be discharged downward through the discharge port 31. With this setting, the subsequent cutting of pine strips can be carried out in an orderly manner, avoiding mutual obstruction and interference between pine strips and affecting normal cutting.

[0049] Please see Figure 2 , Figure 3 and Figure 7 The cutting cylinder 5 is arranged vertically and is open from top to bottom. The top of the cutting cylinder 5 corresponds to the position of the outlet 31. Pine strips falling vertically from the outlet 31 can be aligned and fall into the cutting cylinder 5. A drive cylinder 51 is installed on one side of the bottom end of the cutting cylinder 5. A cutting device 52 is installed on the moving part of the drive cylinder 51. The drive cylinder 51 is used to drive the cutting device 52 to move below the cutting cylinder 5 in a direction perpendicular to the cutting cylinder 5, so as to realize the cutting and retraction.

[0050] The cutting device 52 adopts existing technology and mainly includes a tool holder fixed on the moving part of the drive cylinder 51, a cutting disc mounted on the tool holder, and a drive source mounted on the tool holder for driving the cutting disc to rotate.

[0051] The dispensing mechanism 6 comprises a first guide trough 61, a second guide trough 62, a second electric cylinder 63, and a second drive motor 65. The second drive motor 65 is mounted on the feed pipe 9 via a mounting bracket 651. A vertically extending rotating shaft 652 is fixed on the output shaft of the second drive motor 65. The rotating shaft 652 is coaxial with the bagging cylinder 1. The first guide trough 61 is inclinedly mounted on the top of the rotating shaft 652 and is aligned with the lower end of the cutting cylinder 5. The second guide trough 62 is slidably fitted below the first guide trough 61, and its inclination angle is the same as that of the first guide trough 61. The second electric cylinder 63 is fixed to the side of the second guide trough 62. The end of the telescopic rod of the second electric cylinder 63 is fixedly connected to the side of the first guide trough 61. A vertically penetrating guide cylinder 64 is provided at the lower end of the second guide trough 62, and the top of the guide cylinder 64 is connected to the lower end of the second guide trough 62.

[0052] The bottom of the pine strip that falls into the cutting cylinder 5 can extend to the bottom of the cutting cylinder 5 and fall on the first guide groove 61. The first guide groove 61 plays a blocking and limiting role for the pine strip to be cut in the cutting cylinder 5, preventing the pine strip from falling out directly before it can be cut. At the same time, there is no need to set a fixing structure on the cutting cylinder 5 to fix the pine strip.

[0053] By driving the wire cylinder 51 to work, the cutting device 52 is driven to advance, which can cut the part of the pine strip extending from the bottom of the cutting cylinder 5 into blocks. Since the bottom of the pine block that has been cut off is in contact with the first guide groove 61, and the top is in contact with the uncut pine strip, it is difficult to separate them completely, which affects the pine strip to continue falling. After the cutting blade has completely passed through the pine strip, the wire cylinder 51 drives the cutting device 52 to continue to advance until the blade holder contacts the pine block and pushes the pine block to one side until the pine block is completely separated from the pine strip above and slides down along the first guide groove 61. The pine strip in the cutting cylinder 5 continues to fall and contacts the first guide groove 61, and the cutting step can be repeated. This process can be repeated to cut the pine strip into blocks in an orderly manner.

[0054] In addition, the cutting device 52 is set inside the bagging cylinder 1. The pine wood chips produced by cutting the pine wood strips fall directly into the bagging cylinder 1 and are put into the bag together. They can be used as a supplement to the culture medium components. There is no need to collect and process the pine wood chips separately, which avoids waste of pine wood chips and makes the structure layout reasonable.

[0055] In addition, since the distance between the cutting cylinder 5 and the first guide groove 61 is fixed, the cutting length of the pine strips extending to the bottom of the cutting cylinder 5 is approximately the same each time. Combined with the cutting blade 4 cutting the pine segments evenly, the size of the pine blocks is basically consistent, which further improves the consistency of nutrient supply when the pine blocks are evenly distributed in the bag.

[0056] The material falls onto the first guide trough 61 and slides onto the second guide trough 62, eventually falling into the guide cylinder 64 and then downwards into the bag body. The second electric cylinder 63 extends and retracts, causing the second guide trough 62 to move horizontally along the first guide trough 61, thus adjusting the feeding span on the horizontal plane. The second drive motor 65 rotates, and through the connecting shaft 652, it drives the first guide trough 61, the second guide trough 62, and the guide cylinder 64 to rotate, adjusting the feeding position. This coordinated action ensures that the falling point of the pine blocks changes regularly in each layer, ensuring even distribution of the pine blocks in each layer. Furthermore, the guide cylinder 64, installed at the lower end of the second guide trough 62, extends and restricts the falling of the pine blocks, ensuring accurate landing points.

[0057] The present invention also provides a method for preparing a culture medium for Poria cocos strain, which specifically includes the following steps;

[0058] Step 1: Mix all components of the culture medium thoroughly.

[0059] Step 2: Place the cut pine wood blocks and the mixing material evenly into the olefin bag layer by layer;

[0060] Step 3: Sterilize using a mechanical boiler-free sterilizer for 2 hours.

[0061] It is worth noting that first, the pine blocks are evenly and regularly arranged and fed. Then, the mixing material is fed into the bag through the feed pipe 9 until the mixing material covers all the pine blocks in the same layer. This completes the feeding of one layer. Then, the bag sleeve 2 is driven down to the next layer feeding height. The above process is repeated to achieve uniform feeding layer by layer.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
