Embodiment 1

[0024] When the temperature of the exhaust outlet of the bamboo charcoal burning earth furnace is 80°C-90°C, and the temperature inside the kiln is 350°C-400°C, collect 1000kg of bamboo vinegar stock solution at the smoke exhaust outlet of the kiln, mix it with activated carbon, quartz sand, and cation exchange resin. Separation column, obtain pure vinegar liquid, wherein, the composition of separation column material is quartz sand 75%, activated carbon 5% (303 type unshaped granular activated carbons produced by Sanshan Carbon Co., Ltd., Huzhou, Zhejiang Province), cation exchange resin 20% ( 732 type cation exchange resin produced by Zhejiang Deqing County Environmental Protection Material Factory); put the pure bamboo vinegar solution into a decompression concentrator to concentrate, the decompression concentration temperature is 40 ℃ ~ 90 ℃, and the specific gravity of the concentrated solution is 1.12 , pH2.8, then enter the spray dryer for spray drying, and the dry powde...

Embodiment 2

[0025] When the exhaust outlet temperature of the bamboo charcoal furnace is 140°C-150°C, and the kiln temperature is 750°C-800°C, collect 1000kg of bamboo vinegar stock solution at the smoke exhaust outlet of the kiln, and mix it with activated carbon, quartz sand, and cation exchange resin. Separation column, obtain pure vinegar liquid, wherein, the composition of separation column material is quartz sand 80%, activated carbon 3% (303 type unshaped granular activated carbons produced by Sanshan Carbon Co., Ltd., Huzhou, Zhejiang Province), cation exchange resin 17% ( 732 type cation exchange resin produced by Zhejiang Deqing County Environmental Protection Material Factory); put the pure bamboo vinegar solution into a decompression concentrator to concentrate, and the decompression concentration temperature is 60 ° C ~ 85 ° C, and the specific gravity of the concentrated solution is 1 , pH is 3, then enters the spray dryer for spray drying, and the dry powder obtained is 37.5...

Embodiment 3

[0027] When the temperature of the exhaust outlet of the bamboo charcoal-burning earthen furnace is 100°C to 110°C, and the temperature in the kiln is 500°C to 550°C, collect 1000kg of bamboo vinegar stock solution at the smoke exhaust outlet of the kiln, and directly distill the collected vinegar liquid to obtain pure bamboo vinegar. The vinegar liquid; put the pure bamboo vinegar liquid into the decompression concentrator to concentrate after standing, the decompression concentration temperature is 40 ℃ ~ 50 ℃, the specific gravity of the concentrated solution is 1, the pH is 2.2, and the cation exchange (Deqing, Zhejiang Province) 732 type cation-exchange resins produced by County Environmental Protection Material Factory) extract and separate the required various pure vinegar powders, and it is 38.5 kilograms to obtain dry powder. After analysis: the content of acetic acid is 80wt%, the content of flavonoids is 12wt%, and the content of other organic compounds is 8wt%. Can...

Abstract

The present invention relates to charcoal production with bamboo and wood material and is especially the preparation process of high quality vinegar powder with the vinegar liquid collected during producing charcoal with bamboo and arbor material. The preparation process includes collecting vinegar liquid from charcoal kiln with smoke exhaust temperature of 80-150 deg.c and inside temperature of350-800 deg.c; processing the vinegar liquid with separating column comprising active carbon, quartz sand and cationic exchange resin and subsequent quiescence and filtering or direct distillation toobtain pure vinegar liquid; quiescence to separate and decompressing concentration; and high speed centrifugal spray drying in drying chamber or ion exchange to obtain pure vinegar powder.

Description

technical field [0001] The invention belongs to the field of charcoal production using bamboo or woody arbor plants as raw materials, in particular to the production of high-quality bamboo or woody vinegar powder using vinegar liquid collected during charcoal making from bamboo or woody arbor plants as raw materials Methods. Background technique [0002] Air pollution and water pollution have always been two major environmental problems that have plagued social development. Today, with the deteriorating environment, environmental protection will become an eternal theme. In this context, a bamboo or woody tree plant is used as raw material. In particular, the bamboo vinegar liquid extracted from bamboo as raw material for making charcoal has emerged as a new high-tech bamboo product required by emerging functionality and environmental protection. In the past, the exhaust gas was discharged directly when burning charcoal without collection; later, peopl...
