Description

Technical Field

[0002] Fermentation is one of the important processes in tea processing. Fermentation is a series of chemical changes mainly involving the oxidative polymerization of polyphenol compounds under the promotion of enzymes, thus forming the unique color, aroma and taste of tea. Therefore, fermentation is a key process in the formation of its quality.

[0003] In order to improve the taste of tea and oxidize the tea polyphenols that originally have a bitter taste in tea, it is necessary to control the temperature fluctuations during the fermentation process. Existing heating equipment comes in various forms, but due to the lack of corresponding temperature control facilities, the fermentation of tea is often affected by overheating. Although some devices are equipped with temperature and humidity monitoring devices, the tea leaves need to be stirred during the fermentation process to ensure their uniformity, so they need to be turned over manually, which wastes manpower and time, and the ambient temperature and humidity inside the equipment will be destroyed when the equipment is turned on. At the same time, since the temperature inside the tea fermentation chamber is relatively high, the stirring mechanism set in the chamber will fail due to being in a high temperature state for a long time, and its service life is reduced, which affects the stirring efficiency of the tea leaves.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, the tea fermentation control device provided by the present invention includes a base 1, on which is disposed a fermentation box 2. The fermentation box 2 is internally provided with at least two fermentation chambers 3, so that multiple groups of tea leaves can be fermented simultaneously within the fermentation box 2, thereby improving overall fermentation efficiency. A limiting partition 4 is provided within the fermentation chamber 3, and a tea tray 5 is provided below the limiting partition 4. The limiting partition 4 limits the position of the tea leaves during hot air heating and fermentation, so that the tea leaves can only move within the space between the limiting partition 4 and the tea tray 5, preventing the tea leaves from being blown away by the hot air. The hot air conveying of the tea leaves is achieved by a hot air blower 6 arranged at one end of the base 1. A hot air channel 7 is arranged in the side wall of one end of the fermentation box 2. The hot air is conveyed through the hot air channel 7. An air duct switching mechanism is arranged in the hot air channel 7. The air duct switching mechanism is used to automatically cut off or turn on the hot air conveying temperature when the tea leaves are fermented in the fermentation chamber 3, so as to avoid the temperature of the tea leaves being too high during fermentation. There is no need to manually open the fermentation box 2 to stir the tea leaves. That is, the tea leaves can be fully heated and stirred by the blowing effect of the hot air, which is beneficial to improving the fermentation efficiency of the tea leaves.

[0024] The specific settings are as follows: the hot air blower 6 is connected to an air outlet pipe 8, which is communicated with the hot air channel 7. The hot air is transported to the hot air channel 7 through the rotation of the hot air blower 6 and enters each fermentation chamber 3 to heat and ferment the tea leaves.

[0025] An air supply duct 9 is provided within the tea tray 5. Ventilation grilles 10 are installed on the top of the tea tray 5 and on the limiting partition 4. One end of the hot air duct 7 is connected to the air supply duct 9. A sidewall air outlet grille 18 is installed on one side wall of the fermentation chamber 2, and a top air outlet grille 19 is installed on the top of the fermentation chamber 2. After passing through the air supply duct, the hot air acts on the tea tray 5 and passes through the ventilation grille 10, thereby heating and cooling the tea leaves. After passing through the tea leaves, the hot air flows out through the sidewall air outlet grille 18 or the top air outlet grille 19, respectively, forming a circulation system.

[0026] like Figure 3 or Figure 4 As shown, the air duct switching mechanism includes a first memory metal spring 11 installed in the side wall of one end of the fermentation box 2, a blocking block 12 is slidably installed in the hot air channel 7, one end of the first memory metal spring 11 is connected to the blocking block 12, and a second memory metal spring 13 is installed in the side wall of the other end of the fermentation box 2, one end of the second memory metal spring 13 is connected to the other end of the blocking block 12, a first flow auxiliary channel 14 is provided at the bottom of the blocking block 12, and a second flow auxiliary channel 15 is provided at the bottom of the second memory metal, the second flow auxiliary channel 15 and the hot air channel 7 are interlaced with each other and one end thereof is connected to the outside world.

[0027] The first memory metal spring 11 and the second memory metal spring 13 are both spring-shaped components made of memory metal material. When in use, they will return to a spring-shaped structure after being heated. Figure 3 As shown, in the initial state, the first memory metal spring 11 is in a stretched state, the second memory metal spring 13 is in a compressed state, and the blocking block 12 is on the side close to the second memory metal spring 13. Because it is stretched by the second memory metal spring 13, the hot air channel 7 is in a conductive state. However, since the hot air has a certain high temperature, when the first memory metal spring 11 in the hot air channel 7 is exposed to the hot air for a long time or instantaneously, it will gradually return to the contracted state of the initial spring, that is, it will pull the blocking block 12 to block the hot air channel 7 and cut off the delivery of hot air, thereby preventing the tea from being overheated and affecting the fermentation effect of the tea. At this time, the changed state is as shown in FIG. Figure 4As shown, after the first memory metal spring 11 returns to its initial state, it pulls the blocking block 12 to block the hot air channel 7. At this time, the hot air channel 7 no longer continues to ventilate, but instead flows in from the first circulation auxiliary channel 14 at the bottom of the blocking block 12 and flows out to the outside through the second circulation auxiliary channel 15, forming a cycle. Since the fermentation chamber is connected to the outside world, when the hot air channel 7 stops delivering hot air, the temperature in the fermentation chamber will gradually drop due to the continuous outflow of hot air. Until the second memory metal spring 13 is heated and returns to its initial state, it pulls the blocking block 12 again to realize the conduction of the hot air channel 7, and the tea leaves in the fermentation chamber are intermittently heated again. This cycle repeats.

[0028] Furthermore, an auxiliary push rod 16 is connected to the top sidewall of one end of the blocking block 12, and one end of the auxiliary push rod 16 extends outside the fermentation box 2. The auxiliary push rod 16 can be manually pushed or pulled outside the fermentation box 2 to impart a certain dynamic effect to the first memory metal spring 11 or the second memory metal spring 13.

[0029] A flexible curtain 17 is provided on one side wall of the fermentation box 2, and is positioned above one end of the tea tray 5. During use, the tea tray 5 is pushed into the fermentation box 2 through the flexible curtain 17. After the tea tray 5 is placed, the flexible curtain 17 will fall down automatically, achieving a sealing effect and preventing the hot air in the fermentation chamber from escaping.

[0030] In summary, the tea fermentation control device provided by the utility model avoids overheating of tea leaves by setting up a temperature control facility with an air duct switching mechanism, and there is no need to manually open the fermentation box 2 to stir the tea leaves. The blowing effect of hot air on the tea leaves can enable the tea leaves to be fully heated and stirred, which is beneficial to improving the fermentation efficiency of the tea leaves and ensuring the fermentation quality of the tea leaves.

[0031] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples.
