Description

Technical Field

[0001] The utility model relates to the technical field of dark tea production and fermentation, in particular to cold water humidifying equipment used for Liubao tea production and fermentation. Background Art

[0002] Liubao tea is a type of dark tea. The production process of dark tea generally includes killing green, rolling, piling, drying, etc. Piling is a unique process for dark tea and an important difference from green tea. Fermentation (piling) is crucial for dark tea. During the piling process, microorganisms multiply and metabolize in large numbers, causing complex chemical changes in the substances contained in the tea. During the fermentation process of dark tea, a suitable environment needs to be provided for the activities of microorganisms. Generally, the temperature is kept in a relatively stable range, about 20 to 30 degrees Celsius, and the humidity needs to be maintained between 75% and 90% to promote the active growth and reproduction of microorganisms. Good ventilation is often required, and the air can circulate moderately to provide sufficient oxygen for microorganisms while also draining away excess moisture and odor in time. Through fermentation, the color of tea leaves gradually changes from green to dark brown, the taste becomes mellow, and the soup color turns to red, thick and bright. Fermentation gives dark tea a unique flavor and quality, such as the formation of the unique aroma of aged and woody aromas of dark tea, and a more mellow and smooth taste. At the same time, fermentation can also reduce the irritation of tea to a certain extent, making dark tea more suitable for more people to drink. For example, Anhua black tea, Liubao tea and other black teas.

[0003] According to the "A Pu'er Ripe Tea Fermentation Humidification Equipment" provided by application number 202320743462.7, a humidifying device is set up. When the humidity of the Pu'er ripe tea to be fermented needs to be controlled, the water pump is turned on to discharge the water in the water tank through the conduit, and then discharged into the heating box through the liquid outlet pipe, and then sprayed out water mist through multiple atomizing nozzles. When the water mist contacts the electric heating plate, it will be directly vaporized due to the instantaneous high temperature, and the water vapor will be transported to the fermentation box through the vent to humidify the tea leaves. The water vapor enables the tea leaves to ferment more evenly.

[0004] However, the temperature of the water vapor generated in the above technical solution is relatively high, and it is difficult to control it between 20-30 degrees Celsius, and the fermentation temperature of Liubao tea cannot be guaranteed. In addition, the space in the fermentation box is limited, and the stacking thickness of the tea leaves is not easy to be too large. Sufficient oxygen needs to be provided for the microorganisms, resulting in a limited amount of tea leaves fermented in the fermentation box at one time. Therefore, in view of the above phenomenon, a cold water humidification equipment for the production and fermentation of Liubao tea is proposed to meet the needs of actual use. Utility Model Content

[0040] Working principle: By adding a heating wire 6 to the ultrasonic humidification generator 5, the water in the ultrasonic humidification generator 5 can be heated to about 30 degrees Celsius, and then the water is atomized through the transducer and transmitted to the air guide pipe 7, the air distribution pipe 8 and the fermentation tank 2 through the pipeline in sequence, so that the inside of the fermentation tank 2 maintains a certain humidity, and when the temperature and humidity sensor 11 detects that the temperature in the fermentation tank 2 reaches more than 20 degrees, the heating work of the heating wire 6 is stopped. When the temperature and humidity sensor 11 detects that the humidity of the fermentation tank 2 reaches more than 75%, the power of the ultrasonic humidification generator 5 is gradually reduced, and when the air humidity in the fermentation tank 2 exceeds When the humidity reaches 90%, the ultrasonic humidifier 5 stops working. There are multiple air distribution pipes 8, and the air humidity at different positions in the fermentation tank 2 is increased at the same time. The mist output is controlled by the humidity control component 9.
