Description

Technical Field

[0001] The invention relates to the technical field of tea processing equipment, and in particular to a low-debris tea fermentation production and processing system. Background Art

[0002] Regular consumption of Pu'er ripe tea can reduce fat and weight, lower blood pressure, resist arteriosclerosis, prevent cancer, protect teeth, reduce inflammation and sterilize, protect the stomach and resist aging, and has great value to human health. Pu'er ripe tea has a sweet taste and is consumed by a large number of Chinese people. With the improvement of people's quality of life, consumers are increasingly paying attention to the quality, taste and health benefits of Pu'er ripe tea.

[0003] Generally, tea production and processing systems mainly include withering devices, fermentation devices and drying devices; however, these devices have the following problems: the existing tea drying devices, in order to dry out the moisture of the tea leaves themselves, often cause the tea leaves themselves to become dry and brittle, and often carry a large amount of tea fragments when bottling, which greatly affects the quality of the tea leaves; at the same time, the existing fermentation devices are prone to damage the surface of the tea leaves during the stacking and unstacking processes, resulting in the formation of debris during the fermentation process.

[0016] Compared with the prior art, the beneficial effects of the present invention are at least one of the following:

[0017] 1. A conical filter is designed at the feed inlet of the withering device. When a fan is used to extract the air or smoke inside the withering tank, the suction generated by the rotation of the fan will drive some tea leaves into the feed inlet. When the tea leaves contact the conical filter, due to the conical filter's conical structure, the tea leaves will slide along the side wall of the conical filter and gather between the side wall of the conical filter and the inner side wall of the feed inlet. The conical end of the conical filter always remains transparent and does not affect the use of the fan.

[0018] 2. During the fermentation process in the fermentation screening device, tea leaves can be placed between the pile plates to form a tea pile, and fermentation microorganisms can be inoculated into the tea pile to carry out pile fermentation. When the fermentation temperature exceeds a certain level, the driving cylinder can be started to drive the push rod to extend and retract, which can drive the pile plates to open, and at the same time, the bulking mechanism descends to cool down and unpack, which is beneficial to better temperature control during the fermentation process and to improve the fermentation effect;

[0020] 4. The negative pressure far-infrared drying method is adopted for drying the fermented ripe tea, which combines the two drying methods of negative pressure drying and infrared radiation heating. In the negative pressure environment, since the air pressure inside the tea leaves is greater than the surface pressure of the tea leaves, a pressure gradient is formed that is conducive to the diffusion of water from the inside to the outside, which is conducive to reducing the surface temperature that is too high and excessive drying that causes the surface fiber to peel off and form debris; it is conducive to improving the intensity and uniformity of moisture diffusion, and is conducive to avoiding the brittle cracking of the lower moisture part due to uneven drying of the tea leaves, which is conducive to reducing the debris rate; under negative pressure conditions, the infrared radiation efficiency is improved, and the boiling point of water is reduced, which is conducive to the evaporation of water and the advantages of far-infrared heating drying; while being conducive to the drying of tea leaves, the temperature is reduced, which is conducive to retaining tea polyphenols, polysaccharides and other substances in the tea leaves, and is conducive to improving the quality of tea leaves.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Example 1: Figures 1 to 8The present invention discloses a low-debris tea fermentation production and processing system, comprising a fixing device, a fermentation screening device and a drying device; the fixing device comprises a transparent cover shell 1 and a fixing tank 2 rotatably arranged in the transparent cover shell 1; an electric heating layer is arranged on the inner wall of the fixing tank 2; a feed port 3 is fixedly installed at one end of the fixing tank 2; a conical filter screen 4 is slidably installed in the feed port 3; a fan 5 is movably connected at the end of the feed port 3; the fermentation screening device comprises a fermentation tank 6 and a placement plate 7 arranged inside the fermentation tank 6; filter holes are arranged on the placement plate 7; a pile plate 8 is slidably arranged on the surface of the placement plate 7; the pile plate 8 is connected to a push rod 9; the other end of the push rod 9 is connected to the driving cylinder of the outer wall of the pile plate 8; a bulking mechanism 10 is also arranged on the top of the fermentation tank 6; the drying device adopts a negative pressure far-infrared drying device; in this embodiment, the transparent cover shell 1 and the fixing tank 2 are made of conventional materials with a certain mechanical strength, which can be selected according to needs.

[0032] A conical filter screen 4 is designed at the feed inlet 3 of the fixing device. When the fan 5 is used to extract the air or smoke inside the fixing tank 2, the suction force generated by the rotation of the fan 5 will drive some of the tea leaves into the inside of the feed inlet 3. When the tea leaves contact the conical filter screen 4, due to the conical filter screen 4 having a conical structure, the tea leaves will slide along the side wall of the conical filter screen 4 and gather between the side wall of the conical filter screen 4 and the inner side wall of the feed inlet 3. The conical end of the conical filter screen 4 always remains transparent and does not affect the use of the fan 5. During the fermentation process in the fermentation screening device, the tea leaves can be placed between the pile plates 8 to form a tea pile. The tea pile can be inoculated with fermentation microorganisms, etc., and then the pile fermentation can be carried out. When a certain fermentation temperature is exceeded, the driving cylinder can be started to drive the push rod 9 to extend and retract, which can drive the pile plate 8 to open. At the same time, the bulking mechanism 10 descends to cool and de-pile, which is beneficial to better temperature control during the fermentation process and to improve the fermentation effect.

In the negative pressure environment, since the air pressure inside the tea leaves is greater than the surface pressure of the tea leaves, a pressure gradient is formed that is beneficial to the diffusion of moisture from the inside to the outside, which is beneficial to reducing the surface temperature being too high and over-drying that causes the surface fiber to peel off and form broken residues; it is beneficial to improve the moisture diffusion intensity and uniformity, and is beneficial to avoid the brittle cracking of the lower moisture part due to uneven drying of the tea leaves, and is beneficial to reducing the broken residue rate; under the negative pressure state, the infrared radiation efficiency is improved, the boiling point of water is reduced, which is beneficial to the evaporation of moisture and the advantages of far-infrared heating drying; while being beneficial to the drying of the tea leaves, the temperature is reduced, which is beneficial to retaining tea polyphenols, polysaccharides and other substances in the tea leaves, and is beneficial to improving the quality of the tea leaves.

[0034] When too much tea leaves are gathered, the adjusting plate is pushed to drive the conical filter 4, the leak-proof tube 12, the annular plate (not shown in the figure) and the connecting tube 14 to do synchronous movement. The two sets of telescopic springs 11 are in a compressed state, and the conical filter 4 will push the gathered tea leaves to move. When one end of the connecting tube 14 contacts the internal opening of the feed port 3, the movement stops. At this time, the tea leaves are pushed into the interior of the withering tank 2. The adjusting plate is released, and the two sets of telescopic springs 11 are acted upon by their own elastic force to drive the conical filter 4, the leak-proof tube 12, the annular plate (not shown in the figure) and the connecting tube 14 to do a reset movement.
