DETAILED DESCRIPTION

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] The present application will be further described below in combination with the embodiments.

[0018] Referring to the drawings Figures 1-7 A high-pressure sterilization device for morel culture medium, comprising: The autoclave 1 is the main container of the entire sterilization device, providing a closed environment for the sterilization of morel mushroom culture medium. It can withstand high temperature and high pressure conditions. High-temperature, high-pressure saturated steam is generated inside the chamber to sterilize the culture medium. A container basket 2 for holding the morel mushroom culture medium is movably inserted into the inner cavity of the autoclave 1. The morel mushroom culture medium is placed in the container basket 2, and then the container basket 2 is inserted into the autoclave 1 for sterilization. After sterilization, it can be removed for easy operation and management. A connecting frame 3 is provided inside the autoclave 1, which includes: Two sets of side plates 301 and a connecting shaft 302. The side plates 301 are symmetrically distributed around the axis of the connecting shaft 302 and are fixedly installed on the outer wall of the connecting shaft 302. The outer wall of the connecting shaft 302 is provided with a cross-shaped groove 305. The straight rod 303 is provided in six sets. The six sets of straight rods (303) are rotatably connected to the side plate (301) by pins and are evenly distributed along the circumference of the side plate (301), corresponding to the six sets of holding baskets 2. The holding baskets 2 are installed on the straight rod 303 by a snap-fit ​​structure. The rotary motor 4 is fixedly installed on the outer wall of the autoclave 1. The rotary motor 4 is the power source, providing power for the rotation of the connecting frame 3. The rotary motor 4 extends through the outer wall of the autoclave 1 into the interior of the chamber and is fixedly installed with a locking rod 401 that matches the locking slot 305. The locking rod 401 is inserted into and locked in the locking slot 305. After the rotary motor 4 is started, the output shaft rotates, driving the locking rod 401 to rotate. The locking rod 401 drives the connecting shaft 302 to rotate through the cooperation with the locking slot 305, thereby driving the entire connecting frame 3 and the holding basket 2 to rotate, so that the culture medium is heated more evenly.

[0019] The snap-fit ​​structure includes a connecting block 201 and a snap-fit ​​block 304. The connecting block 201 is fixedly welded to the outer wall of the container basket 2. The bottom of the connecting block 201 has an installation groove 202. The snap-fit ​​block 304 is fixedly set on the outer wall of the straight rod 303. The installation groove 202 is movably sleeved on the top of the snap-fit ​​block 304, so that the container basket 2 is stably installed on the straight rod 303, and at the same time, it is convenient to disassemble and install.

[0020] A bracket 307 is rotatably connected to the outer wall of the connecting shaft 302. A support leg 5 is rotatably connected to the outer wall of the bracket 307 via a hinge. When support is needed, the support leg 5 is rotated downwards so that the bottom of the support leg 5 contacts the ground to form support. When support is not needed, the support leg 5 is rotated upwards to retract the support leg 5, adapting to different support needs.

[0021] The bottom of the support leg 5 has a groove, and the inner wall of the groove is rotatably connected to a movable wheel 501 via a pivot, which reduces the friction when the connecting frame 3 moves, and facilitates the movement and adjustment of the connecting frame 3 inside or outside the autoclave 1.

[0022] Insert rods 308 are fixedly connected between multiple sets of supports 307. A fixing block 101 is fixedly installed on the inner wall of the autoclave 1. A sliding groove is opened on the outer wall of the fixing block 101, and the insert rods 308 are connected and movably inserted into the sliding groove. The insert rods 308 are fixedly connected between multiple sets of supports 307, which enhances the overall stability of the equipment structure. When the connecting frame 3 moves, the insert rods 308 slide in the sliding groove of the fixing block 101 to ensure the smooth movement of the connecting frame 3.

[0023] A marker block 306 is fixedly installed on the outer wall of the connecting shaft 302 to indicate the status of the connecting shaft 302, such as rotation position, initial position, etc., so as to facilitate the operator's observation and operation.

[0024] Working principle: In use, by lowering the support leg 5 and placing the caster wheel 501 on the ground, the operator can easily remove the entire connecting frame 3 system from the autoclave 1. Then, the container basket 2 is lifted, aligning the mounting groove 202 on the connecting block 201 at its bottom with the locking block 304 on the straight rod 303 and sliding it downwards, thus securely mounting the container basket 2 onto the connecting frame 3. After loading, the connecting frame 3 is pushed back into the autoclave 1, ensuring that the insert rod 308 between the supports 307 accurately slides into the groove of the fixing block 101 fixed to the inner wall of the chamber, while simultaneously ensuring that the cross-shaped locking groove 305 at the end of the connecting shaft 302 fully engages with the locking rod 401 on the output shaft of the rotary motor 4. After closing the chamber door, the equipment is started, and high-temperature, high-pressure saturated steam begins to flow into the autoclave 1, simultaneously... When the rotary motor 4 is powered on, it acts as a power source. Its output shaft drives the clamping rod 401 to rotate. The clamping rod 401 transmits torque to the connecting shaft 302 through the engagement of the clamping groove 305. This, in turn, drives the two sets of side plates 301 and the six sets of straight rods 303 on them to rotate slowly together. Finally, the container basket 2 and the culture medium inside it rotate at a uniform speed inside the chamber. This rotation process effectively breaks the natural convection pattern of steam, making the heat distribution more uniform, avoiding sterilization dead zones, and promoting the dispersion of condensate, thereby significantly improving the thoroughness and consistency of sterilization. After the sterilization process is completed, the rotary motor 4 is stopped first. After the pressure and temperature inside the chamber return to normal, the chamber door is opened, and the connecting frame 3 is moved out again using the moving wheels 501. The container basket 2 can then be easily removed, completing the entire sterilization process.

[0025] The above examples are only used to illustrate the technical solutions of the present application, and are not limiting; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
