Embodiment 1
[0033] Bamboo charcoal powder preparation: a pilot test was carried out in a vertical moving bed carbonization furnace, using bamboo chips (about 36cm in length) with an average moisture content of 39%, the temperature of each temperature measurement point, drying zone A is 150 ℃, pre-carbonization zone B Is 275℃, carbonization zone C is 450℃, observe when heating up figure 1 The D zone shown is the temperature at different locations in the combustion zone. When the temperature in the combustion zone, such as d2, is too low, open the small hole in the combustion zone and introduce air to burn on the spot to increase the temperature in the area and control the bamboo to move down. The temperature of the combustion zone experienced during the process was raised to 700°C at a rate of 5°C / min and kept for 40 minutes, and then at a rate of 5°C / min from 700°C to 1100°C and kept for 2 hours, the bamboo charcoal cooling pipe and bamboo vinegar were condensed The device adopts natural c...

[0039] Preparation of bamboo charcoal powder: a pilot test was carried out in a 16-tube conjoined column-tube moving bed carbonization furnace. Mengzong bamboo chips (about 40cm in length) with an average moisture content of 30% were used. The temperature of each temperature measurement point was 200 in the drying zone. ℃, the pre-carbonization zone B is 270℃, and the carbonization zone C is 500℃. When the temperature rises, part of the combustion gas is introduced from the external combustion type and part of the non-condensable gas in the bamboo vinegar liquid condenser is burned at the same time, so that the temperature of the combustion zone is 15℃ / min The temperature is increased to 750℃ and kept for 80min at a rate of 15℃ / min, and then the temperature is increased from 750℃ to 1500℃ and kept for 8h at a rate of 15℃ / min. Water vapor is sprayed in the 1500℃ area for 60min. The bamboo charcoal cooling pipe and bamboo vinegar liquid condenser adopt natural Cool, the discharge ...

[0045] The preparation of bamboo charcoal powder is the same as in Example 1. Then the prepared bamboo charcoal is used to prepare charcoal powder with a particle size of 8000-10000 mesh.
[0046] The preparation method of tea juice is as follows: (1) First, wash the perilla leaves and tea leaves and smash them. Among them, the tea leaves are Pu-erh tea and white tea mixed with 1:1.5; mix the purple with the weight ratio of 1:5. The sesame leaves and tea leaves are soaked in deionized water for 1.5 hours, and then poured into a countercurrent extraction machine for extraction to obtain a coarse filtrate; the coarse filtrate is initially filtered with a precision filtration membrane containing a polypropylene fiber membrane filter element to remove the coarse filtrate (2) The preliminary filtrate is filtered by ultrafiltration, and the ultrafiltration permeate is concentrated with a reverse osmosis membrane at 40°C to obtain the first concentrated solution with a solid content of ...
