[0053] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Example

[0055] like Figures 1 to 4The diagram illustrates an energy-saving tea steamer and a specific embodiment of the tea steaming process. The energy-saving tea steamer includes:

[0056] The container 1 has a support base 2 on its top surface. The support base 2 has multiple first through holes 3 connecting the inside and outside of the container 1. The bottom of the container 1 can be equipped with wheels to facilitate movement of the container 1. A door can also be provided on one side of the container 1. The number of support bases 2 can be one or two, etc., and this embodiment is not limited to this.

[0057] The housing 4 is disposed inside the receiving box 1, and a steam generator is disposed inside the housing 4; wherein, wheels may be provided at the bottom end of the housing 4 to facilitate the movement of the housing 4 and to facilitate the placement of the housing 4 inside the receiving box 1.

[0058] A tea barrel 5 is mounted on the support base 2, and the tea barrel 5 has an opening facing upwards.

[0059] A filter assembly is disposed inside the housing 1 and communicates with the tea barrel 5 through the first through hole 3;

[0060] A steam recovery assembly is installed on the receiving tank 1;

[0061] The tea barrel 5 contains tea leaves to be steamed. The filter assembly is adapted to filter water droplets in the steam generated by the steam generator, and the steam recovery assembly is adapted to recover the residual steam after steaming. The steam generated by the steam generator flows from the bottom to the top of the tea barrel 5. After the tea leaves are softened by steaming, the residual steam flows out from the opening at the top of the tea barrel 5 and is then recovered by the steam recovery assembly. If the water droplets in the steam are not filtered, a large number of water droplets will accumulate at the bottom of the tea barrel 5, easily flowing to the surface of the receiving box 1, resulting in a large amount of water accumulation on the surface of the receiving box 1. If the residual steam after steaming is not collected, the steam after steaming can easily cause air pollution, such as particulate matter pollution detached from the surface of the tea leaves.

[0062] Specifically, regarding the steam recovery component, this embodiment can employ the following method: for example, the steam recovery component can be a vacuum pump positioned directly above the tea barrel 5 to extract residual steam within the tea barrel 5. One end of the vacuum pump can be connected to a recovery tank via a pipeline. When the steam travels from the vacuum pump to the recovery tank, it can be cooled, and the recovery tank collects the cooled liquid. Of course, this embodiment is merely an example illustrating the specific method of the steam recovery component, and it is not intended to limit it. Those skilled in the art can modify it according to actual circumstances to achieve the same technical effect.

[0063] Furthermore, the steam generator is used to perform a tea steaming operation, which includes the following steps:

[0064] S1. Turn on the steam generator, set the steaming time to 15-30 seconds, and the steam temperature to 75℃-90℃.

[0065] S2. Compress and shape the tea leaves;

[0066] S3. Dry the tea leaves.

[0067] The steam generator can be a conventional evaporator with a power of 6000-7500W, a steam pressure of 0.2-0.7MPa, and a steam flow rate of 150-450ml / min. The steam generation time and temperature can be set by the user.

[0068] It should be noted that the pressing operation can be carried out directly inside the tea barrel 5. After pressing and shaping, cover it with a cloth bag to fix the shape, and then dry it.

[0069] Furthermore, prior to step S1, the tea leaves undergo a withering process, wherein the withering process includes:

[0070] The tea leaves are spread out for 12-18 hours;

[0071] The tea leaves are withered to remove moisture until the moisture content is 30%–50%; the withering temperature is 20℃–30℃; and the humidity of the withering environment is 40%–60%.

[0072] Continue to spread the tea leaves out for 4-8 hours until the moisture content of the tea leaves is 20%-30%, the oxygen concentration is 25%-40%, and the temperature is 25℃-40℃.

[0073] Continue to spread the tea leaves out for 4-8 hours until the moisture content is 12%-15%, and the spreading temperature is 25℃-35℃.

[0074] Before steaming, the tea leaves need to undergo withering, which can be carried out in a withering room. Temperature and humidity-controlled withering rooms are standard equipment and will not be elaborated further. The purpose of withering is to evaporate moisture from the tea leaves and increase their resilience. During withering, a tiered withering system can be installed in the withering room, and the thickness of the withered tea leaves can be controlled between 1cm and 3cm. The withering room can be equipped with a circulating air system and a dehumidification system. In the initial stage of withering, the circulating air and dehumidification system ensure that the fresh leaves lose moisture evenly.

[0075] Furthermore, step S3 includes:

[0076] Spread the tea leaves out for 1 hour (preset time), at a temperature of 40℃-60℃, a humidity of 40%-80%, and an oxygen concentration of 25%-40%.

[0077] Continue to spread the tea leaves out until they are dry to a moisture content of 9%–12%, for a time of 16 hours (preset), at a temperature of 50℃–70℃, a humidity of 20%–50%, and an oxygen concentration of 20%–30%.

[0078] The preset time can be selected as 8 hours. Step S3 can be carried out in the drying room. The drying room with controllable temperature, humidity and oxygen concentration is existing technology and will not be described in detail.

[0079] The low-temperature steaming in step S1 effectively protects the surface of the tea leaves and the activity of internal enzymes. The maturation process in step S3 further enhances the aging effect, significantly improving the aroma, color, and taste of the tea. Figure 4 The figure shown is a comparison of the aroma distribution trends of tea samples treated with traditional high temperature and low temperature steaming with a preset time of 8 hours.

[0080] Furthermore, the housing 4 includes:

[0081] Inlet 6;

[0082] Air outlet 7, which is connected to the filter assembly;

[0083] Both the water inlet 6 and the air outlet 7 are connected to the steam generator via pipelines. The steam generated by the steam generator enters the filter assembly through the air outlet 7. The air outlet 7 is connected to the filter assembly via pipelines, allowing water to be added to the steam generator through the water inlet 6. Optionally, a filter can be installed at the water inlet 6. When adding water to the steam generator, the housing 4 can be moved out of the housing 1, or water can be added through the pipeline to the water inlet 6. The number of air outlets 7 should be no less than the number of the support base 2 and the tea canister 5, ensuring that each tea canister 5 can ultimately be connected to an air outlet 7.

[0084] Furthermore, the bottom surface of the tea barrel 5 is provided with a plurality of second through holes 8, through which steam entering the filter assembly enters the tea barrel 5 via the first through hole 3 and the second through hole 8.

[0085] Furthermore, the filtering component includes:

[0086] The filter housing 9 is disposed inside the receiving box 1, and its upper end is fixedly connected to the top surface of the receiving box 1;

[0087] An air inlet 10 is disposed on the outer side wall of the filter housing 9 and communicates with the inner side of the filter housing 9.

[0088] The filter screen 11 is disposed inside the filter housing 9 and is located at the connection between the air inlet 10 and the filter housing 9.

[0089] The liquid outlet 12 is located at the bottom of the filter shell 9 and communicates with the inner side of the filter shell 9. A pipeline is provided at the liquid outlet 12.

[0090] The steam generated by the steam generator enters the inner side of the filter shell 9 through the air inlet 10. The filter screen 11 is adapted to filter water droplets in the steam, and the obtained water droplets flow out through the liquid outlet 12 along the inner wall of the filter screen 11 and the filter shell 9. The air inlet 10 and the air outlet 7 can be connected by a pipeline, so that the steam from the steam generator passes through the air outlet 7, the air inlet 10, the filter screen 11, the filter shell 9 and the support base 2 in sequence, and enters the tea barrel 5, thereby softening the tea leaves in the tea barrel 5.

[0091] Furthermore, the filtering component also includes:

[0092] The collection tank 13 is installed inside the container tank 1. The liquid flowing out of the outlet 12 can enter the collection tank 13 through a pipeline, or it can be directly discharged to an external collection pool, etc. Because it does not contain steam, there is no problem of air pollution.

[0093] Furthermore, the steam recovery assembly includes:

[0094] A recycling channel 14 is provided through the upper side of the container 1. One end of the recycling channel 14 is located at the opening of the tea barrel 5, and the other end of the recycling channel 14 is located inside the container 1 and is provided with a pipeline.

[0095] Centrifugal fan 15 is installed on the recycling channel 14;

[0096] The centrifugal fan 15 is adapted to drive the steam at the opening of the tea barrel 5 into the recovery channel 14.

[0097] The recycling channel 14 is fixedly connected to the receiving box 1. The top of the recycling channel 14 is located at the opening of the tea barrel 5. Under the action of the centrifugal fan 15, the residual steam is extracted. The bottom of the recycling channel 14 can be connected to the collection box 13 or to an external collection pool. The cross-section of the recycling channel 14 can be a rectangle with a large perimeter, so that the residual steam has a large contact area with the outside, making it easier to exchange heat. This allows the steam to cool into water droplets within the recycling channel 14, thus eliminating the problem of air pollution.

[0098] Furthermore, the steam generator is an instantaneous steam generator.

[0099] Traditional steam generators obtain steam by heating water through burning coal or charcoal. This method results in low coal utilization. The instantaneous steam generator of this application can generate steam quickly and energy-efficiently.

[0100] In addition, this application integrates the steam generator, filter assembly and steam recovery assembly into the housing 1, which makes it less likely for the temperature inside the housing 1 to be lost, and makes it less likely for the steam generated by the steam generator to cool down before steaming tea. The utilization rate of the steam generator is high, which plays an energy-saving role.

[0101] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
