Embodiment 1
[0023] Bamboo charcoal powder preparation: Pilot test was carried out in a vertical moving bed dry distillation carbonization furnace, with bamboo chips (about 36cm long) with an average moisture content of 39%, the temperature of each temperature measurement point, the drying area A was 150 ° C, and the pre-carbonization area B 275°C, carbonization zone C is 450°C, when the temperature rises, observe the temperature of different positions in zone D, that is, the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, and introduce air to burn nearby. , to increase the temperature at this place, and control the temperature of the combustion zone experienced by the bamboo during its downward movement to 700°C at a rate of 5°C / min and keep it for 40 minutes, and then increase the temperature from 700°C to 1100°C at a rate of 5°C / min And keep it warm for 2 hours, the bamboo charcoal cooling pipe an...
Embodiment 2
[0029] Preparation of bamboo charcoal powder: a pilot test was carried out in a 16-tube conjoined moving bed dry distillation carbonization furnace, with Mengzong bamboo chips (about 40cm long) with an average moisture content of 30%, the temperature of each temperature measurement point, and the drying area A was 200 ℃, pre-carbonization zone B is 270 ℃, and carbonization zone C is 500 ℃. When the temperature rises, part of the combustion gas introduced from the external combustion type and part of the non-condensable gas of the bamboo vinegar liquid condenser are combusted at the same time, so that the temperature of the combustion zone is 15 ℃ / min The temperature was raised to 750°C at a rate of 15°C / min and held for 80 minutes, and then the temperature was raised from 750°C to 1500°C at a rate of 15°C / min and held for 8 hours. Water vapor was sprayed into the 1500°C area for 60 minutes. The bamboo charcoal cooling pipe and the bamboo vinegar liquid condenser used natural Co...
Embodiment 3
[0035] The preparation of bamboo charcoal powder is with embodiment one. Then the prepared bamboo charcoal is prepared into charcoal powder with a particle size of 8000-9000 mesh.
[0036] The preparation method of the tea juice is as follows: (1), first, wash and pulverize the perilla leaves and tea leaves, wherein the tea leaves are cooked Pu-erh tea and white tea mixed at a ratio of 1:1.5; Perilla leaves and tea leaves are fully soaked in deionized water for 1.5 hours, then poured into a countercurrent extractor for extraction to obtain a crude filtrate; the crude filtrate is initially filtered with a precision filter membrane containing a polypropylene fiber membrane filter element, and the crude filtrate is removed. (2), the preliminary filtrate is subjected to ultrafiltration, and then the ultrafiltration permeate is concentrated with a reverse osmosis membrane at 40 ° C to obtain the first concentrated solution with a solid content of 15%. Take half of the first concen...
