Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a charcoal kiln.

[0002]

BACKGROUND OF THE INVENTION As is well known, charcoal has long been known in part as an excellent cooking fuel that maximizes the taste of the ingredients. However, it has been used again by many people because of the recent outfitting and ease of use. In addition, recently, it has been found that various aspects other than fuel are beneficial (effective) to our lives, and are widely introduced, for example, in newspapers, magazines, and television. Among them, examples of well-known effects include dampproofing and insect repellent effects in homes, deodorant effects, water purification effects, soil improvement effects, mental calming effects, negative (-) ion effects, and the like. In addition, attention has been paid to the diversification of hobbies and the global environment. That is, thinning materials for growing forests or pruned foliage of home garden trees are used. It is thought that if this thinned wood, branches and leaves, etc. are carbonized to clean recycled fuel from ancient Japan, or carbonized, finely crushed and mixed with soil, the soil will be improved and become the most familiar ecological cycle.

[0003] In view of the above, various charcoal kilns and tools and methods related to charcoal firing have been introduced or put into practical use. However, there are few structures that can be easily moved, that can be repeatedly used, or that can be used easily and efficiently by any number of people. As a document, there is a mobile charcoal kiln of Japanese Utility Model No. 5-81259. The contents consist of a kiln body having a fire hole and a chimney hole, a ceiling lid that closes the opening of the kiln body, and a chimney provided in the chimney hole. There is a feature that can be achieved.

[0004]

Conventionally, no charcoal kiln suitable for easily moving and easily charcoal burning by anybody has been proposed or marketed, and improvement thereof is desired. .

[0005] The above document is a device useful for solving the conventional problem. However, since it is made of iron, it has some problems in terms of heat retention, and leaves a problem in the beauty of the finish or in the enhancement of the function. In addition, the degree of sealing between the kiln body and the ceiling lid is not sufficient, and a smooth transition to carbonization cannot be expected.

[0006]

Means for Solving the Problems The invention of claim 1 is to improve the sealing degree of the kiln during carbonization to produce good quality charcoal, or to make the finish beautiful and functional by using the heat retention of diatomaceous earth. To produce excellent charcoal.

A kiln body made of diatomaceous earth having a suction port and an exhaust port, a shielding body made of diatomaceous earth which is attached to and detachable from an opening of the kiln body, and the opening is provided. A charcoal kiln comprising: a fluid object filling a gap between the gas inlet and the shield; a plug for closing the inlet and the outlet; and a chimney detachably provided at the outlet.

Another object of the present invention is to improve the ease of ignition and the combustion efficiency.

A second aspect of the present invention is a charcoal kiln having a configuration in which projections are provided on the inner bottom surface of the kiln body.

The third object of the present invention is to secure the shape of the kiln body and to manufacture the kiln body by a conventional method.

[0013] A third aspect of the present invention is a charcoal kiln in which the kiln body is constituted by means for cutting out a diatomaceous earth mass.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As is well known, charcoal burning varies depending on the properties of the carbonaceous material, the state at the time of charcoal burning, climatic conditions, time and the like, and the handling described later is an example. The selection of the carbonaceous material and the length, size, thickness, etc. of the carbonaceous material are arranged, and these are made as uniform as possible. And it is preferable that the carbonaceous material is sufficiently dried, but in the case of raw wood, it is difficult to remove.

The suction port and the exhaust port of the kiln body are each closed with a suction plug with an exhaust plug. After removing the shield and opening the kiln body, carbon material is filled through the opening. The carbon material is made to protrude at an appropriate interval and at the center portion by using the projection (a), and the ignition of the ignition material for ignition described later is improved. Attach a chimney to the exhaust port (b). Thereafter, an ignition material is placed on the filled carbon material, and the ignition material is ignited (c). Desirably, the ignited ignition material is dropped into the gap between the carbonaceous materials to improve the combustion efficiency (d).
Next, a shield is provided on the kiln body to hermetically close the kiln body.
(E). Then, paying attention to the fact that the fire has circulated over substantially the entire kiln body and the carbon material and the color of the smoke, it is confirmed that the color of the smoke is white (f). In this case, the suction port is adjusted to increase the amount of air suction into the kiln body (g). The smoke changes from a yellowish nose to a clear, non-irritating odor in blue. Then, wait for the seal to close while watching the smoke change. The smoke changes from the white color at the center of the water vapor to the white with a turquoise color. Usually, it is about 1-2 hours. By catching this timing, the air flow into and out of the kiln body is stopped. Specifically, the intake port is plugged, the chimney is removed, and the exhaust port is plugged (I). And, in order to further improve the degree of sealing (sealing degree) of the kiln body, sand is filled in the gap between the opening and the shield.
(Nu). This sealing of the kiln body is the basic operation of producing carbonization, which takes several hours and waits for the kiln body to cool down. About 2 to 4 hours. Then, when the kiln body has cooled, the shield is removed and the charcoal is taken out.

[0014]

An embodiment of the present invention will be described below.

Reference numeral 1 denotes a kiln body having an opening 111 formed by hollowing out a diatomaceous earth lump. A wall 113a of the kiln body 1 has a suction port 113 and an exhaust port reaching a cavity 112 of the kiln body 1. 1
