Description

Technical Field

[0001] The invention relates to the technical field of Pu'er tea pile fermentation, in particular to a pile fermentation aging machine and a pile fermentation process for preparing Pu'er tea with floral, fruity and caramel aroma. Background Art

[0002] In the processing technology of Pu'er tea, the most critical link is the process of piling, humidifying and keeping warm the tea materials to achieve fermentation. This process is also called the Pu'er tea pile aging process. The pile fermentation technology is a process of rapid aging of Pu'er tea through artificial natural fermentation. During the fermentation process, the environmental temperature and humidity, fermentation time, tea stacking density and stacking amount must be strictly controlled. Through pile fermentation, Pu'er tea not only has a soft taste, but also has outstanding health functions due to the production of a large amount of theabrownin, soluble polysaccharides and other ingredients.

[0003] The existing Pu'er poor fermentation pile usually piles the sun-dried green tea to a certain height (usually around 70CM), sprinkles water on it, and covers it with linen to promote the action of tea enzymes. It ferments for about 24 hours under the action of wet heat. After the tea is converted to a certain degree, it is spread out to dry. The tea leaves after the fermentation will have different degrees of fermentation.

[0004] However, in the prior art, the existing pile fermentation is usually operated manually. During the pile fermentation process, the tea leaves need to be piled up manually in a quantitative manner, and the fermentation environment of the tea leaves needs to be manually controlled in real time. After the fermentation is completed, the tea leaves need to be transported to the drying position for drying. This not only requires operators to perform real-time monitoring, which increases labor costs, but also is inconvenient to operate. In addition, in order to facilitate the stacking of tea leaves, the tea leaves are usually directly piled on the ground to prevent bamboo mats from being used for fermentation, which results in poor sanitation. If a support is provided, it will inevitably increase the trouble of loading and unloading.

[0005] In addition, a special pile smell will be produced during the fermentation process of tea leaves, and its smell is similar to that of moldy tea, which is often difficult to accept. Due to the special nature of the pile smell, which is similar to the smell of mold, many inferior teas with moldy smells enter the market as good ones, causing market chaos, which is not conducive to the healthy development of the tea market. Therefore, how to solve the pile smell produced after the fermentation of tea leaves is also an urgent problem that needs to be solved.

The amount of tea added to the housing 1 is measured by the size of the housing 1, and the filling of the tea can be assisted by controlling the vibration motor 11 during the feeding process;

[0060] S4, continue to convey tea leaves until the full material sensor 13 detects that the infrared light is continuously blocked for more than 5 seconds, indicating that the tea leaves are full, and then the driving motor 19 can be controlled to stop working. If the infrared light emitted by the full material sensor 13 is not blocked after the driving motor 19 stops working, the driving motor 19 is controlled to work again until the full material sensor 13 detects that the infrared light is blocked for more than 5 seconds again, and then the vibration motor 11 and the driving motor 19 are controlled to stop working. After 30 seconds, the cover plate cylinder 3 is controlled to retract, thereby driving the cover frame 3 and the linen cloth 6 to cover the tea leaves, and the linen cloth 6 is covered with the tea leaves;

During the unloading process, the empty material sensor 14 continuously detects intermittent obstructions (tea leaves falling obstruction), so no action is taken until the empty material sensor does not detect any obstruction for 30 seconds. At this time, it is determined that the inside of the shell 1 is in an empty state, and the next cycle of piling operation can be performed;

7. The pile-fermenting machine for producing Pu'er tea with floral, fruity and caramel aroma according to claim 6, characterized in that: The bottom of the shell (1) is fixedly connected to a support frame (15); the transfer bucket (16) is placed below the shell (1) and located on the inner side of the support frame (15); a universal wheel is fixedly installed on the bottom of the transfer bucket (16); a handle is fixedly connected to the outer side of the transfer bucket (16); a flow guide frame (26) is fixedly connected between the inner walls of the shell (1); the flow guide frame (26) is arranged as a square-shaped frame; and the inner side of the flow guide frame (26) is arranged as an inclined surface.

8. The pile-fermenting machine for producing Pu'er tea with floral, fruity and caramel aroma according to claim 7, characterized in that: A vibration motor (11) is fixedly mounted on the outer side of the housing (1). The vibration motor (11) is used to properly vibrate the tea leaves during pile fermentation and is also used to assist in feeding the tea leaves.

9. The pile-fermenting machine for producing Pu'er tea with floral, fruity and caramel aroma according to claim 8, characterized in that: A controller (22) is fixedly connected to the outer side of the support frame (15); the drive motor (19), the electric humidifier (10), the vibration motor (11), the temperature and humidity sensor (12), the material full sensor (13), and the material empty sensor (14) are all electrically connected to the controller (22).

10. The pile fermentation process of the pile fermentation machine for producing Pu'er tea with floral, fruit and caramel aroma according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, preparation work before stacking, control the cover plate cylinder to extend so that the cover frame is in an open state relative to the shell, and control the pad plate cylinder to retract so that the bamboo mat is in a closed state relative to the shell; S2, pouring the sun-dried green tea into the loading hopper and waiting for the loading mechanism to load; S3, by controlling the driving motor to work, driving the auger to rotate, thereby realizing feeding, so that the sun-dried green tea is transported along the auger and falls from the feeding pipe onto the bamboo mat in the shell; S4, when the tea material is full, the sensor detects that the infrared light is continuously blocked for more than 5 seconds, indicating that the tea material is full, and then the driving motor is controlled to stop working, and after 30 seconds, the cover cylinder is controlled to retract, thereby driving the cover frame and linen cloth to cover the tea material; S5, using a temperature and humidity sensor inside the shell to detect the temperature and humidity inside the shell, and controlling the operation of the electric humidifier to continuously provide heat and humidity inside the shell, so that the temperature inside the shell is controlled at 40-45 degrees Celsius, and the humidity inside the shell is controlled at 80%-90%; through wet pile fermentation, the enzyme contained in the tea leaves can react with the unique floral and fruity components in the tea leaves to produce a unique floral and fruity aroma; then the temperature is increased to bake the tea leaves to remove the moisture in the tea leaves and maintain the caramel floral and fruity aroma of the tea leaves; S6, after the pile is continuously fermented for 24 hours, the cover plate cylinder and the pad plate cylinder are controlled to extend, so that the cover frame and the bamboo mat are opened at the same time, and the tea leaves fall into the transfer bucket under the action of gravity. During the unloading process, the vibration motor can be used to make the shell aim to assist unloading; S7, transporting the tea leaves in the transfer bucket to a drying location for drying.
