Description

Technical Field

[0001] The present invention relates to an apparatus for making fermented tea.

[0002] Specifically, it relates to a dynamic tea fermenting machine with a rolling function and its usage method. Background Art

[0003] In the traditional process of making fermented tea, generally, the withered tea leaves need to go through the processes of rolling and fermentation successively. The rolling time is about 1 - 2 hours, and the fermentation time is 4 - 6 hours. If the external environmental temperature is relatively low, the fermentation time can be as long as 6 - 8 hours. At the same time, the rolling time needs to be strictly controlled, otherwise it will affect the fermentation effect. If the rolling time is too long, there may even be a situation where the tea leaves do not ferment.

[0004] It can be known that tea fermentation requires appropriate temperature and humidity. Previously, the Chinese patent with the patent number ZL201410372163.2 disclosed a patent for an integrated rolling and fermenting machine for Gongfu black tea. Its technical solution is to add an air inlet hole in the middle of the pressure cover, and then introduce temperature - controlled and humidity - controlled oxygen - rich air into the air inlet hole through a blower to achieve the effect of shortening the fermentation and rolling time. However, during the trial use, it was found that during the use process, the tea leaves directly contacted the air inlet hole, and the constantly moving tea leaves during the rolling process were extremely easy to block the air inlet hole, resulting in the failure of air supply. At the same time, the tea leaves around the air inlet hole were prone to overheating and adhesion, resulting in the failure of fermentation. In addition, the space between the pressure cover and the rolling barrel was completely open, and during the use process, the gas was easy to disperse, resulting in energy waste. Moreover, the accuracy of temperature control and humidity control was greatly affected by the external environment and was not easy to accurately control. Summary of the Invention

[0087] Step 4: Heavy pressure stage. The upper and lower driving devices drive the pressure cover to move down 10 - 15 cm for 40 - 50 min. The rotation speed of the rolling disk is 30 - 45 r / m, the air supply temperature is 30 - 40 °C, and the air supply humidity is 80 - 90%;

[0088] In addition, the distance that the pressure cover moves down can be 10 cm, 12 cm, 15 cm, etc.; the time can be selected as values such as 40 min, 43 min, 45 min, 48 min, 45 min, etc. according to needs; the rotation speed can be selected as 30 r / m, 32 r / m, 35 r / m, 37 r / m, 40 r / m, 45 r / m, etc. according to needs; the air supply temperature can be selected as 35 °C, 38 °C, 40 °C, etc.; the air supply humidity can be selected as 80%, 82%, 85%, 88%, 90%, etc.

[0089] Step Five: Light pressing stage. The upper and lower driving devices drive the pressing cover to move upward by 10 - 15 cm for 20 - 30 min. The rotation speed of the rolling disc is 20 - 35 r / m, the air supply temperature is 30 - 40 °C, and the air supply humidity is 80 - 90%, until the tea leaves are discharged and deblocked.

[0090] In addition, the upward movement distance of the pressing cover can be 10 cm, 12 cm, 15 cm, etc.; the time can be selected as 20 min, 23 min, 25 min, 28 min, 30 min, etc. according to needs; the rotation speed can be selected as 20 r / m, 22 r / m, 25 r / m, 27 r / m, 30 r / m, 35 r / m, etc. according to needs; the air supply temperature can be selected as 35 °C, 38 °C, 40 °C, etc.; the air supply humidity can be selected as 80%, 82%, 85%, 88%, 90%, etc.

[0091] During the fermentation and rolling process of tea leaves, the pressure, humidity, and temperature inside the barrel can be adjusted in real time. The pressing follows two principles: light - heavy - light and slow - fast - slow. For different raw materials, different pressures will be selected. Old tea is pressed heavily, and tender tea is pressed lightly. For different seasons and temperatures, when the temperature is low, the set temperature is slightly higher, and when the temperature is high, the set temperature is slightly lower. Sensors can be used to monitor the temperature and humidity inside the fermentation barrel, and a fan is used to send humid and hot atomized gas with controlled humidity and temperature into the fermentation barrel to intelligently control the temperature and humidity. When the temperature is high, the fermentation time is short, and vice versa.

[0092] Comparison of the rolling time between the traditional process and the process of this application: The traditional rolling takes 60 - 90 minutes, plus 240 - 360 minutes of fermentation, with a total time of 300 - 390 min. The total time of this process is 150 - 200 min, saving nearly half of the time on average. At the same time, because the process time is shortened, the energy consumption is greatly saved. After the two process flows are intelligently combined, the operation process is simplified, and the operation difficulty and labor intensity are reduced. Moreover, due to being sealed by a sealing cover and sending air through the air intake gap, in actual application, the situation of tea leaf blockage due to faults is zero, and unattended operation can be realized. Due to the full rolling and fermentation of tea leaves, the produced tea has the following advantages: Appearance: The tea is in the shape of tight and knotted strips, complete, clean, of uniform size, and consistent color; Soup color: More bright and red, clear to the bottom; Aroma: Fragrant, accompanied by a floral aroma, and the grassy smell is removed more thoroughly; Taste: Sweet and mellow; Leaf bottom: The brewed tea leaves unfold completely, without gaps, with a soft and delicate texture.

[0093] The above has described several embodiments of the present invention in detail, but the described content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should fall within the scope covered by the patent of the present invention.
