Description
Technical Field
[0001] The present invention relates to the field of fermentation equipment, and more particularly to a uniform fermentation device for primary processing of medicinal tea products. Background Art
[0002] During the primary processing of herbal tea, uniform fermentation is crucial for improving product quality. As a key step in improving tea quality, fermentation directly impacts the taste, aroma, and nutritional content of herbal tea. Currently, a variety of fermentation equipment for the primary processing of herbal tea products is available on the market, meeting production needs to a certain extent.
[0003] However, the existing uniform fermentation device still has some problems that need to be solved. For example, the fermentation chamber of the existing uniform fermentation device is mostly a square structure, and a bracket is fixedly welded inside the fermentation chamber. After the medicinal tea products are flattened inside the stainless steel material frame, they are directly stacked layer by layer on the bracket to facilitate uniform heating and moistening inside the fermentation chamber in the later stage, and then fermentation. Although such a structure is relatively simple and convenient to use, each time the fermented medicinal tea products are replaced, the door of the fermentation chamber must be fully opened before the material frame can be taken out for replacement. When the door is fully opened to replace the medicinal tea products, the temperature, humidity and other environmental indicators inside the fermentation chamber will inevitably be destroyed by the outside air entering. After the medicinal tea products are replaced and the door of the fermentation chamber is closed again, the uniform fermentation device needs to re-adjust and generate the temperature, humidity and other environmental indicators inside the fermentation chamber. Therefore, the structure of such a uniform fermentation device is not only not conducive to the continuous feeding and discharging fermentation of medicinal tea products, but also not conducive to reducing the energy consumption of the device during the continuous fermentation of medicinal tea products. Therefore, we propose a uniform fermentation device for the primary processing of medicinal tea products to solve the above-mentioned problems. Summary of the Invention

[0017] The operating principle of the uniform fermentation device for the primary processing of this kind of medicinal tea product is: First, the front door 103 is opened, and the sliced tea products are evenly spread on each material frame 12 inside the fermentation chamber 101. Then, the front door 103 is closed and confirmed to be sealed, so that the interior of the fermentation chamber 101 is in a closed environment. Then, the device is started by the control switch on the fermentation machine housing 1, and various indicators of the fermentation environment are set through the control panel. At this time, the sliced tea products on each material frame 12 can be fermented (the fermentation of the sliced tea products inside the fermentation chamber 101 includes but is not limited to electronic components such as a humidifier, a humidity sensor, an electric heating rod, a temperature sensor, their installation locations, and working principles, which are already known public technologies and will not be described in detail here); When the fermentation of the medicinal tea product is completed and the medicinal tea product on each material frame 12 needs to be replaced, it is only necessary to rotate the handwheel 21 of the driving mechanism 13, and the worm 19 and the worm gear 16 are driven to rotate through the connection of the transmission shaft 20, and then the center disk 4 of the rotary bracket mechanism 3 is driven to rotate through the connection of the main shaft 17, first the first support tube 5 and the support rod 6 in the rotary bracket mechanism 3 are rotated to a vertical state, and the conical ball head seat 8 at the top of the support rod 6 can be aligned with the through hole 107. At this time, the rotation of the handwheel 21 can be stopped, and then the handle 204 on the reset plate 2 is pulled to rotate it around the positioning axis, and the arc fitting section 201 is misaligned and not overlapped with the through hole 107, and the highest end of the S-shaped lifting section 202 is aligned with the through hole 107. At this time, the first support rod 6 can be pushed outward by the support spring 7 through the through hole 107, and the ball head on the conical ball head seat 8 of the first support rod 6 directly contacts the bottom of the highest end of the S-shaped lifting section 202; At the same time, after the first support rod 6 is pushed out, the first support rod 6 drives the bracket 10 and the material frame 12 to move upward as a whole through the connection of the connecting shaft 9, and the material frame 12 moves up and just stays inside the opening frame 105, and the sealing frame 1201 just contacts the bottom edge of the feeding opening 104, and the gap between the inner edge of the feeding opening 104 and the bottom outer edge of the material frame 12 is blocked. At this time, the sealing cover 106 can be opened to expose the first material frame 12, and then the fermented food inside the first material frame 12 can be put into the container. The herbal tea product is taken out and replaced with a new unfermented herbal tea product, and then the sealing cover 106 is re-covered, and the reset plate 2 is rotated in the opposite direction by using the handle 204. During the reverse rotation, the first support rod 6 is squeezed back into the fermentation chamber 101 by using the structure of the S-shaped lifting section 202 and the through hole 107, and the arc-shaped fitting section 201 overlaps with the through hole 107 again and fits tightly, preventing external air from entering the fermentation chamber 101 through the through hole 107 and damaging the fermentation environment. After the first support rod 6 is squeezed back into the fermentation chamber 101 and reset, the material frame 12 of the replaced medicinal tea product will also be reset to the fermentation chamber 101. At this time, the medicinal tea product replacement process inside the material frame 12 on the first support rod 6 inside the fermentation chamber 101 is completed. Similarly, the hand wheel 21 is turned again to align the conical ball head seat 8 on the second support rod 6 with the through hole 107, and the medicinal tea product inside the material frame 12 on the second support rod 6 is replaced until the medicinal tea product inside all the material frames 12 inside the fermentation chamber 101 are replaced. There is no need to shut down the machine or open the front door 103 during the entire replacement process, and it has strong continuous operation performance. Moreover, since the front door 103 does not need to be opened during the replacement of the medicinal tea product, the interior of the fermentation chamber 101 will not be directly exposed to the outside air, and the preset temperature, humidity and other environmental parameters inside the fermentation chamber 101 are less affected. The device does not need to be restarted or briefly started to maintain the fermentation environment conditions inside the fermentation chamber 101, which greatly reduces the operating energy consumption of the device and achieves the effect of energy saving and emission reduction.
[0018] Example 2: In view of the above embodiment 1, for further description, refer to Figure 2-Figure 9 The arrangement of the reset plate 2 is to facilitate the rotation of the reset plate 2, and to utilize the outer structure of the arc-shaped fitting section 201 and the S-shaped lifting section 202 to release the support rod 6 through the through hole 107 to the outside of the fermentation machine housing 1, or to compress the support rod 6 through the through hole 107 to reset it to the inside of the fermentation chamber 101, thereby achieving the effect of controlling the extension and contraction of the support rod 6 and the lifting and lowering of the material frame 12; The sealing frame 1201 at the bottom of the material frame 12 is convenient for the material frame 12 to fit on the bottom of the feeding opening 104 and contact the sealing ring after it rises, thereby blocking the gap between the inner edge of the feeding opening 104 and the outer edge of the bottom of the material frame 12, and preventing the outside air from entering the fermentation chamber 101 through the gap during the material change process; during the material change process, the outside air can only temporarily enter the fermentation chamber 101 through the mesh holes on the material frame 12. Compared with the existing fermentation device that directly opens the front door 103 to change the material inside the material frame 12, the impact on the internal environment of the fermentation chamber 101 is greatly reduced; A connecting shaft 9 is fixedly installed inside the shaft hole 601 of the support rod 6, and a bracket 10 is rotatably connected to the end of the connecting shaft 9. A counterweight plate is rotatably connected to the bracket 10 at the bottom position of the connecting shaft 9 by a bolt, and a number of counterweight blocks 11 are fixedly installed on the counterweight plate by bolts. The axis of the connecting shaft 9 and the axis of the bolt are on the same vertical line. The structural design can lower the center of gravity of the bracket 10 and keep the center of gravity in a downward state, ensuring that the openings of each material frame 12 are always facing upward during the rotation of the rotating bracket mechanism 3, thereby avoiding the overturning of the material frame 12 and the spillage of the medicinal tea products; The drive mechanism 13 is structured in such a way that its transmission is connected via the worm gear 16 and the worm 19 , and utilizes the self-locking property of the worm gear transmission to facilitate the positioning of the support rod 6 after rotation.
[0019] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
