Description

  The present invention relates to a method for producing bamboo charcoal or charcoal crafts.

Methods for producing crafts from bamboo charcoal or charcoal are known. Patent Document 1 below discloses a method of manufacturing bamboo charcoal crafts by putting raw bamboo in a charcoal pot to produce bamboo charcoal and then cutting the bamboo charcoal into a desired shape.
JP-A-2-266901

  Bamboo charcoal and charcoal are hard but brittle, so it is not easy to cut into a desired shape. Therefore, the present invention intends to obtain bamboo charcoal or charcoal craft by carbonizing a craft obtained by cutting bamboo or wood. One of the problems in this case is that ordinary bamboo charcoal or charcoal When a craft is put in a charcoal pot and carbonized as in the method of manufacturing charcoal, a considerable part is ashed and it is difficult to keep the original shape of the craft.

  The present invention provides a method for producing bamboo charcoal or charcoal crafts that solves the above problems and can be carbonized while keeping the original shape without ashing bamboo or wooden crafts. For the purpose.

  The present invention is a metal container such as a costume can, a drum can, an oil can, an 18 liter can, etc. It is characterized in that after being put in and sealed, fuel is arranged around it and the fuel is ignited to spontaneously carbonize the craft.

  Spontaneous carbonization of crafts can be carried out in the same way as manufacturing charcoal and bamboo charcoal in a charcoal baking pot with a metal container containing crafts, or by covering the metal container with fuel such as firewood. It can also be done by igniting.

  According to the method of the present invention, after spontaneous carbonization by the above-described method, the metal container taken out from the kettle was opened and the craft was inspected. It was confirmed that the skin remained in its original shape.

Example 1
1 and 2 show a charcoal pot used in the method of the present invention. As shown in FIG. 1, the charcoal chamber 1 has an egg-shaped horizontal section, a shed 2 and a flue 3, and the whole is shown. Constructed with refractory bricks and refractory concrete. In the figure, 4 is an auxiliary chimney, 5 is a barrier, 6 is a refining hole, 7 is a smoke outlet, and 8 is a drain.

Next, an example of the manufacturing method according to the present invention performed using the charcoal pot will be described.
First, a certain length of round bamboo 9 is vertically arranged on the floor surface of the carbonization chamber 1 and spread over the entire floor surface, and then a steel costume can 10 is placed thereon. The costume can 10 has a size as shown in FIG. 3 and repeats the operation of placing a chaff inside the lid 10a and then embedding bamboo or wooden crafts in the chaff and covering it with the chaff. The crafts wrapped in rice husks are put in several layers, and the lid 10a is closed and sealed.

  The amount of rice husk used is about 1/2 to 2/3 of the capacity of the costume can 10, but when canna waste is used instead of the rice husk, it is about 2/3 of the capacity of the costume can 10. About 5/6 is necessary.

  On the costume can 10 placed on the round bamboo 9, the further divided bamboo 9 is arranged side by side and stacked. Next, the round bamboo 9 is stacked in a sideways direction on the shed 2, and after closing the shed 2, the round bamboo 9 in the shed 2 is ignited using a burner. When the temperature in the carbonization chamber reaches 80 to 90 ° C. after ignition, the burner is stopped and the door (not shown) of the shed 2 is closed. Then, when the temperature in the carbonization chamber reaches 140 to 150 ° C. as it is for a whole day and night, the lower air port is temporarily closed among the air ports above and below the door, and then the temperature of the carbonization chamber 1 is 200 ° C. or higher. When it reaches, close the air vent on the door. If left undisturbed for a whole day, the temperature inside the carbonization chamber drops naturally, and when it reaches room temperature, the door opens. In this state, most of the bamboo around the costume can 10 was in an incinerated state, but when the costume can 10 was taken out and opened and the inside was inspected, the craft was carbonized with its chaff in its original form. It was confirmed that

Example 2
As shown in FIG. 4, a wood chip 13 is laid around a 10 cmφ chimney 12, and a steel 18 liter can 14 containing crafts and rice husks is placed on it as well as the above-described costume can 10. The wood chips 13 were further covered to a height of about 1 m, and the upper layer wood chips 13 were ignited. As the wood chips 13 burned, new wood chips 13 were supplied 5 to 6 times in a timely manner, and after 8 hours had passed, they were left as they were. After a few hours, the 18-liter can 14 was taken out of the ash while the wood chips were burned out, and the inside was inspected. As in Example 1, the craft was carbonized with its rice husk kept in its original form. confirmed.

  The present invention can provide a product obtained by carbonizing a craft product obtained by cutting bamboo or wood.

Claims (1)

  Crafts obtained from cutting materials made of bamboo and wood are sealed in a metal container with rice husks, canna scraps, or leaves, and then fuel is placed around them, and the fuel is ignited. Then, a method for producing bamboo charcoal or charcoal crafts characterized in that the crafts are spontaneously carbonized.
