Embodiment 1

[0015] The invention discloses a production process of bincho charcoal, which selects Uoka wood or Qinggang wood as carbon wood, and prepares the finished bincho charcoal in a carbonization kiln through technical steps such as drying, steaming, carbonization, calcination, and cooling. The specific steps are as follows:

[0016] (1) Drying: first lay a layer of firewood evenly in the carbonization kiln, then place ebony or green wood on the bottom firewood, semi-close the kiln door and chimney, and burn and heat with combustible wood at the kiln door for 12 days .

[0017] (2) Steaming: Extinguish the combustible wood at the kiln door, close the kiln door and chimney, and let the charcoal wood be steamed in the kiln for 14 days. When the temperature in the kiln reaches 60°C, stop the steaming.

[0018] (3) Carbonization: Close the kiln door, leave two small holes with a diameter of 2cm for oxygen supply, open the chimney by one third, light the bottom firewood, and carry out l...

Embodiment 2

[0022] The invention discloses a production process of bincho charcoal, which selects Uoka wood or Qinggang wood as carbon wood, and prepares the finished bincho charcoal in a carbonization kiln through technical steps such as drying, steaming, carbonization, calcination, and cooling. The specific steps are as follows:

[0023] (1) Drying: first lay a layer of firewood evenly in the carbonization kiln, then place ebony or green wood on the bottom firewood, semi-close the kiln door and chimney, and burn and heat with flammable wood at the kiln door for 14 days .

[0024] (2) Steaming: Extinguish the combustible wood at the kiln door, close the kiln door and chimney, and let the charcoal wood be steamed in the kiln for 7 days. When the temperature in the kiln reaches 80°C, the steaming is terminated.

[0025] (3) Carbonization: Close the kiln door, leave two small holes with a diameter of 4cm for oxygen supply, open the chimney by one third, light the bottom firewood, and carry...

Embodiment 3

[0029] The invention discloses a production process of bincho charcoal, which selects Uoka wood or Qinggang wood as carbon wood, and prepares the finished bincho charcoal in a carbonization kiln through technical steps such as drying, steaming, carbonization, calcination, and cooling. The specific steps are as follows:

[0030] (1) Drying: Firstly lay a layer of bottom firewood evenly in the carbonization kiln, then place ebony or green wood on the bottom firewood, semi-close the kiln door and chimney, and burn and heat with combustible wood at the kiln door for 18 days .

[0031] (2) Steaming: Extinguish the combustible wood at the kiln door, close the kiln door and chimney, and steam the carbon-making wood in the kiln for 10 days. When the temperature in the kiln reaches 70°C, stop the steaming.

[0032] (3) Carbonization: close the kiln door, leave two small holes with a diameter of 3cm for oxygen supply, open the chimney for one third, light the bottom firewood, and carry...

Abstract

The invention discloses a production technique of white charcoal, which comprises the following steps: selecting Wugang wood or Qinggang wood as carbon preparation wood, and carrying out drying, closed evaporation, carbonization, smelting and cooling in a carbonization kiln to obtain the white charcoal finished product. According to the carbon preparation technique, Wugang wood or Qinggang wood in remote mountains is selected as the raw material, and is subjected to long-time (30 days or so, which is 2-3 times of the firing time of common white charcoal) low-temperature carbonization and high-temperature smelting at 1000 DEG C above to obtain the white charcoal. Since the wood is subjected to sufficient closed evaporation and shrinking in the kiln, the earlier stage adopts low-oxygen carbonization which consumes fewer wood substances, and the later stage adopts high-temperature oxygen-rich smelting and oxidation reaction. The produced charcoal has the advantages of high strength, high heating value (up to 8800 kilocalories), metallic luster on the cross section of the product, smooth surface, fewer cracks, compact structure, and low breaking tendency by knocking; and the density is up to 1.05-1.10 g / cm<3>, and the hardness is up to 5.6-5.8 which is greater than that of pig iron.

Description

technical field [0001] The invention belongs to the technical field of charcoal processing technology, and in particular relates to a process for processing and manufacturing Bincho charcoal by using ebony wood or qinggang wood as raw materials. Background technique [0002] "Binchotan" is a high-grade charcoal product made of hard Uoka and Qinggang wood with traditional charcoal burning techniques and techniques. "Binchotan" belongs to the Japanese folk scientific name, and the Chinese folk scientific name is "white charcoal". It is collectively referred to as "charcoal" in Chinese commerce. "Binchotan" is a symbol of craftsmanship. The one made of Uoka wood is called "Uoka Binchotan"; the one made of Qinggang wood is called "Qinggang Binchotan". [0003] Uoba wood and Qinggang wood belong to Fagaceae and Quercus; they are mainly produced in Southwest China, India and Myanmar. Characteristics: air-dry density is 0.95-1.15g / cm 3 , high strength, high hardness, high oilines...
