Description

Technical Field

[0001] This invention relates to the field of edible fungi equipment technology, specifically to an edible fungi sterilization boiler with a tumbling loading mechanism. Background Technology

[0002] During the cultivation of edible fungi, the substrate usually needs to be sterilized by high-temperature steam.

[0003] Currently, traditional mushroom sterilization boilers mostly employ static sterilization methods, where containers filled with mushroom substrate are manually or using trolleys to be placed into the boiler for heating. When processing bulk substrate, the slow heat penetration from the outside to the inside due to the static state of the material easily leads to uneven heating. Furthermore, after sterilization, traditional boilers typically require manual removal and transport of the substrate to the bagging station. This not only increases the workload for operators but also exposes the sterilized substrate directly to the outside air during multiple transfers, increasing the probability of secondary contamination by other microorganisms. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a mushroom sterilization boiler with a tumbling loading mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A sterilization boiler for edible fungi with a tumbling loading mechanism includes: a sterilization boiler section comprising a boiler body mounted on a base frame, wherein the boiler body has an annular chamber connected to a steam supply device, and the annular chamber has multiple steam discharge holes; a rotating cylinder section comprising a rotating cylinder with spiral ridges inside, wherein the two ends of the rotating cylinder are respectively connected to a tail cover and a head cover, forming an internal cavity; a boiler cover section comprising a boiler cover detachably connected to the boiler body, wherein a drive motor connected to the rotating cylinder via a transmission gear set is mounted on the boiler cover; and a moving section comprising an upper connecting frame connected to the boiler cover, a reduction motor mounted on a moving support frame, and a linear module connected to the base frame, wherein the working end of the reduction motor is connected to the upper connecting frame, and the linear module is drivenly connected to the moving support frame.

[0006] Preferably, the rotating cylinder is a barrel-shaped structure with a larger diameter at one end and a smaller diameter at the other end.

[0007] Preferably, the tail cap is connected to the end of the rotating cylinder with a larger diameter, and the head cap is detachably connected to the end of the rotating cylinder with a smaller diameter.

[0008] Preferably, the rotating cylinder and the boiler cover are connected by bearings.

[0009] Preferably, the boiler body is provided with a ring support frame, the rotating cylinder and the ring support frame are in sliding contact via ball bearings, and the ring support frame is used to support one end of the rotating cylinder.

[0010] Preferably, the transmission gear set includes a gear and a gear ring, the gear is connected to the working end of the drive motor, the gear ring is connected to the outer wall of the rotating cylinder, and the gear and gear ring mesh.

[0011] Preferably, the linear module is used to drive the dynamic support frame to make linear displacement movement in the horizontal direction, so as to move the boiler cover and the rotating cylinder together into or out of the boiler body.

[0012] Preferably, the geared motor is used to control the upper connecting frame to change its angle, so as to drive the rotating drum and the boiler cover to switch between a horizontal state and an inclined state.

[0013] Preferably, the plurality of steam exhaust holes are spaced apart circumferentially along the wall of the annular chamber, and the steam exhaust holes connect the annular chamber and the sealed cavity.

[0014] Preferably, one end of the upper connecting frame is axially connected to the working end of the geared motor, and the upper connecting frame deflects at an angle as the geared motor is driven axially.

[0015] Preferably, the boiler cover and the boiler body are detachably locked together by fastening bolts.

[0016] Preferably, the rotating cylinder is axially inserted into the interior of the boiler body under the drive of the linear module, and the circumferential outer wall of the rotating cylinder is completely surrounded by a sealed cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This device features a rotating cylinder with spiral ridges. During sterilization, the drive motor, through a gear set, enables the rotating cylinder to rotate smoothly. Due to the spiral ridges inside, the substrate undergoes continuous convective tumbling during rotation. Compared to traditional static stacking sterilization, the tumbling and flowing of the material allows it to come into more even contact with the high-temperature steam heat emitted from the annular chamber, eliminating localized heating dead zones and helping to improve the overall sterilization quality. This device cleverly utilizes the moving part for multi-degree-of-freedom adjustment. By driving the upper connecting frame to tilt via the geared motor, the substrate can be conveniently filled at the angle shown in the figure. By driving the moving support frame to translate via the linear module, the rotating cylinder can be axially sent into the boiler body for horizontal sealing and sterilization. This mechanized reciprocating connection design eliminates the heavy physical labor of traditional manual handling of materials in and out of the boiler. During the discharge stage after sterilization, the rotating drum is pulled out as a whole and readjusted to an inclined state by the moving part. At this time, the head cover is removed and the drive motor is started. The spiral convex pattern inside the rotating drum, combined with its own tilt angle, can directly discharge the mushroom material from the end with the smaller diameter and directly bag it. This structure allows the sterilized mushroom material to be bagged immediately after discharge, reducing unnecessary intermediate transfer and exposure links, and to a certain extent reducing the risk of secondary contamination of the material by miscellaneous bacteria during the discharge process.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] One embodiment provided by the present invention: refer to Figures 1-5 A sterilization boiler for edible fungi with a tumbling loading mechanism.

[0022] It includes a sterilization boiler section 01, a vortex section 02, a boiler cover section 03, and a moving section 04.

[0023] The sterilization boiler section 01 includes a boiler body 11 and a base frame 12. The boiler body 11 is mounted on the base frame 12. The boiler body 11 has an annular chamber 111 inside. The annular chamber 111 is connected to a steam supply device. The annular chamber 111 has steam discharge holes facing inward, and multiple steam discharge holes are arranged in a ring.

[0024] The rotating cylinder 02 includes a rotating cylinder 21, which is a barrel-shaped structure with a larger diameter at one end and a smaller diameter at the other end. A tail cap 22 is connected to the larger diameter end of the rotating cylinder 21, and a head cap 23 is detachably connected to the smaller diameter end of the rotating cylinder 21. The rotating cylinder 21, the tail cap 22, and the head cap 23 form an internal cavity, which is used to hold the culture substrate.

[0025] The inner wall of the rotating cylinder 21 is provided with spiral ridges that extend along the axis.

[0026] The exterior of the rotating cylinder 02 is provided with a boiler cover 03, which includes a boiler cover body 31. A drive motor 32 is installed in the boiler cover body 31. The working end of the drive motor 32 is connected to the rotating cylinder 21 through a transmission gear set 33. The transmission gear set 33 includes a gear and a gear ring. The gear is connected to the working end of the drive motor 32, and the gear ring is connected to the outer wall of the rotating cylinder 21. The gear and the gear ring mesh. When the drive motor 32 starts, it drives the transmission gear set 33 through the working end, and then drives the rotating cylinder 21 to rotate through the transmission gear set 33.

[0027] The rotating cylinder 21 and the boiler cover 31 are connected by bearings. The rotating cylinder 21 and the support ring 112 are in sliding contact with each other by ball bearings. The support ring 112 is used to support one end of the rotating cylinder 21 and, while supporting, ensures that the rotating cylinder 21 can rotate along the axis.

[0028] The boiler cover 31 and the boiler body 11 are detachably connected. When the boiler cover 31 and the boiler body 11 are connected, the boiler body 11 and the boiler cover 31 form a sealed cavity. Steam can enter this sealed cavity through the holes on the annular chamber 111, thereby heating the rotating cylinder 21. The heat will be transferred to the culture medium inside the rotating cylinder 21 to achieve sterilization.

[0029] The movable part 04 includes an upper connecting frame 41, which is connected to the boiler cover 31. One end of the upper connecting frame 41 is connected to a reduction motor 43, and the working end of the reduction motor 43 is connected to the upper connecting frame 41. The reduction motor 43 is mounted on a movable support frame 42, and a linear module 44 is provided at the bottom of the movable support frame 42. The linear module 44 is connected to the base frame 12.

[0030] By controlling the linear module 44, the movable support 42 can be moved, thereby driving the boiler cover 03 and the rotating drum 02 to move together.

[0031] Working principle: S1, Loading preparation stage (tilted state) Initially, the overall structure is in a tilted position (e.g. Figure 5 (As shown). First, remove the tail cap 22 from the larger diameter end of the rotating cylinder 21. Then, pour the culture medium to be sterilized into the internal cavity of the rotating cylinder 21 through this end. Since the rotating cylinder 22 is tilted at this time, and the rotating cylinder 21 is a conical structure with a larger diameter at one end and a smaller diameter at the other, the poured culture medium can be stably stored in the internal cavity of the rotating cylinder 21. After loading, reconnect the tail cap 22 to the rotating cylinder 21.

[0032] S2, Feeding and Sealing Stage (Horizontal Reset and Closing) After the material is loaded, the geared motor 43 in the moving part 04 is started by the external controller. The working end of the geared motor 43 drives the upper connecting frame 41 to deflect at an angle, thereby adjusting the boiler cover part 03 and the rotating drum part 02 from an inclined state to a horizontal state.

[0033] Subsequently, the linear module 44 is activated. Since the linear module 44 is connected to the base frame 12, its operation drives the moving support frame 42 to move linearly in the horizontal direction, thereby causing the boiler cover 03 and the rotating cylinder 02 to move forward together, allowing the rotating cylinder 21 to be smoothly inserted axially into the boiler body 11. After complete insertion (e.g....) Figure 1 and Figure 2 (As shown in the diagram), one end of the rotating cylinder 21 makes sliding contact with the ring support 112 inside the boiler body 11 through ball bearings, and the ring support 112 provides support for it.

[0034] Finally, the boiler cover 31 and the boiler body 11 are detachably locked using fasteners such as bolts, so that a sealed cavity for sterilization is formed between the boiler body 11 and the boiler cover 31.

[0035] S3, Steam sterilization and tumbling homogenization stage After sealing, the external steam supply equipment is activated. The generated high-temperature, high-pressure steam first enters the annular chamber 111 inside the boiler body 11, and then is evenly sprayed into the sealed cavity through multiple annularly distributed steam discharge holes arranged inwards in the annular chamber 111. The steam directly contacts the outer wall of the rotating cylinder 21 and exchanges heat. The heat is transferred through the cylinder wall of the rotating cylinder 21 to the culture medium in its internal cavity, achieving high-temperature heat conduction sterilization.

[0036] While the steam is heating, the drive motor 32 in the boiler cover 03 is started. The working end of the drive motor 32 drives the gear in the transmission gear set 33 to rotate. The gear meshes with the gear ring connected to the outer wall of the rotating cylinder 21, thereby causing the rotating cylinder 21 to rotate around its own axis. At this time, the support ring 112 supports and ensures the smooth rotation of the rotating cylinder 21. During the rotation of the rotating cylinder 21, the spiral convex textures along the axis on its inner wall continuously agitate and scoop up the fungal material inside (the direction of movement is as follows). Figure 2 (As shown by the middle arrow), the substrate continuously undergoes axial convection and tumbling within the internal cavity, thereby ensuring that all substrate is homogenized and heated, eliminating dead zones in local sterilization.

[0037] S4. Cooling and Aseptic Bagging Stage After sterilization for the preset time is completed, the system stops to dissipate heat. Once the internal substrate has cooled to a suitable bagging temperature, the bolts between the boiler cover 31 and the boiler body 11 are removed.

[0038] Subsequently, the linear module 44 in the moving part 04 is activated again. The linear module 44 drives the moving support frame 42 to move in the opposite direction, axially pulling the vortex section 02 out of the boiler body 11 of the sterilization boiler section 01 as a whole. After the moving support frame 42 has been driven to the end position, the reduction motor 43 is activated to control the upper connecting frame 41 to tilt again, so that the vortex section 02 and the boiler cover section 03 are restored to their original positions. Figure 5 The tilted state shown.

[0039] At this point, the cap 23 at the smaller diameter end of the rotating cylinder 21 is removed, and a corresponding mushroom bag is fitted onto the discharge end. Finally, the drive motor 32 is restarted to rotate the rotating cylinder 21. During rotation, the internal spiral ridges, combined with the tilt angle of the rotating cylinder 21 and the weight of the material, generate an outward axial thrust, efficiently and smoothly discharging the sterilized mushroom material from the smaller diameter end of the rotating cylinder 21. The mushroom material falls directly into the fitted mushroom bag, completing the bagging process in one step, effectively avoiding secondary contamination by miscellaneous bacteria caused by traditional transfer processes.

[0040] 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.
