Description

The present invention relates to a combustion method and apparatus using pelletized carbides made of trees containing bark such as cedar, firewood, firewood, pine, etc., and its major features are combustion temperature, duration, thermal stability and the like. A heat generating plane with good planar uniformity can be obtained.

Conventionally, there are various combustion apparatuses used for cooking food, such as burning with firewood or charcoal, a method using gas, a method using petroleum, and an electromagnetic type. Of these, combustion with charcoal does not give a flame, but charcoal is in a block shape, and over time, it becomes quite hot, and food and the like burn.

For example, Patent Document 1 sets charcoal in a pack on a charcoal pot with a charcoal tray on the bottom, ignites the charcoal with a household gas stove, then transfers to a combustion pot, and places a wire mesh on the combustion pot. It is configured to bake ingredients.

Further, Patent Document 2 discloses that a charcoal heating space is formed by storing white charcoal between upper and lower wire meshes in a main body in the shape of a pan, and as soon as heating by an external heat source is performed, charcoal baking is performed. It can be baked by placing ingredients on the wire mesh above, and white coal is not mainly used as fuel, and in order not to ignite the white coal, a structure is provided so that the fire is not cut off and the temperature of the white coal is not raised. The point which can be conveniently used like a pot, without having to replace white charcoal is disclosed.

Utility Model Registration No. 3077562 Japanese Patent Laid-Open No. 10-300091

However, since the thing of the said patent document 1 is in the pack which is a fine metal net between the charcoal made of stainless steel or iron, the charcoal is also in a block shape, so the temperature during combustion rises. Combustion is an accelerated chain reaction, and the temperature continues to rise with the amount of oxygen supplied. In the case of charcoal, the temperature reaches 350 to 700 ° C. depending on the material, size, and amount of stacking. In addition, there are disadvantages such as the temperature under the wire mesh on which food is placed is not uniform. Therefore, a heat generation plane having good combustion temperature, duration, thermal stability and planar uniformity cannot be obtained.

Also, Patent Document 2 is one in which cut white charcoal is arranged on a wire mesh. In Patent Document 2, although white charcoal is not ignited, it is heated to 500 degrees C or less. White coal is a high-density charcoal, and has a high heat storage amount. When the amount of water absorption decreases, it naturally oxidizes and burns slowly. In this way, white coal has a high density and is difficult to ignite, but it has a long combustion time, a long burn, and a high temperature. Therefore, the heating temperature is increased. Therefore, this method also cannot obtain a heat generation plane with good combustion temperature, duration, thermal stability and planar uniformity.

Therefore, the present invention solves the above-mentioned technical problem. Combustion that keeps the combustion temperature low, quickly ignites, spreads uniformly over the entire combustion surface after ignition, and combustion continues while maintaining a stable temperature. It is also an object to provide a method and apparatus thereof.

Is fitted into the upper end opening of a container-type combustion support base having an opening at the top, ignites the pellet carbide of the fuel support base, takes air from an air supply port of the combustion support base, and receives the pellet carbide with the pellet carbide. The combustion object on the frame was heated or baked, and a combustion method using pellet charcoal was used.

The invention of claim 2 is the invention of claim 1, wherein each pellet carbide has an outer diameter of 3 to 8 mm. A combustion method using pellet charcoal having a length of 3 to 30 mm was used.

The invention of claim 3 is the combustion method of pelletized charcoal according to the invention of claim 1 or 2, wherein the pellet carbide contains a binder containing 20% or less of an inorganic substance containing clay.

A large number of pellet carbides containing 2 to 20% are laid flat with a certain thickness, a wire mesh-like receiving frame is provided in the upper opening of the fuel cradle, and the fuel cradle is placed at the upper end. A combustion apparatus using pelletized charcoal, which is detachably fitted into the upper end opening of a container-type combustion support base having an opening, and is provided with an air supply port that can be freely opened and closed on the outer peripheral surface of the combustion support base.

The invention of claim 8 is the invention of claim 7, wherein each pellet carbide has an outer diameter of 3 to 8 mm. A combustion apparatus using pellet charcoal having a length of 3 to 30 mm was used.

According to the first to sixth aspects of the present invention, the pellet carbide used in the present invention burns gently due to the flame retardancy of the bark contained therein. Moreover, it can be used at a stable temperature suitable for the purpose from a low temperature to a high temperature by a method and an apparatus capable of controlling the combustion temperature from 60 ° C to 700 ° C. A wide and uniform temperature distribution and duration can be set by adjusting the thickness of pellet carbide and the intake air, which is impossible with conventional charcoal. In addition, since it is a carbide, it does not generate a flame during combustion and is safe.

In addition, this pellet carbonized carbonized pellet shaped product (outer diameter 3-8 mm, length 3-15 mm) from wood containing bark such as cedar, oak, pine, etc. Is. This carbide is characterized by containing 2 to 20% of inorganic components, for example, oxides or salts of silicic acids, Ca, K, P, Fe, Mg, Al, Ze and the like.

In recent years, it has been elucidated that the role of an ion pump with minerals, particularly K ions, Ca ions, Na ions, etc., is essential for cell activity and cell growth in plant growth. In this invention, paying attention to the fact that the inorganic component is concentrated in the bark, pellet carbide made of wood containing the bark component is used. The bark has a flame retardancy because its bark composition has improved drought resistance and heat resistance, which protects itself from natural fires such as lightning. Therefore, the use of pellet carbide containing a large amount of bark as fuel is disadvantageous compared to other fuels in terms of calories, is weak in price and quantity, and is profitable. Is not progressing.

Therefore, it was discovered that the inorganic substance contained in the pelletized carbide with an increased proportion of the flame retardant bark acts as a catalyst to control the combustion rate (chain reaction) and temperature. Utilizes the action of a so-called combustion moderator, and has high thermal conductivity characteristics and uniformity while maintaining high flatness heat generation with a slight lamination (10 mm to 20 mm) for a long time. .

Moreover, especially according to each invention of Claims 3-5, a flame retardance can be improved more and moderate combustion can be obtained.

Moreover, according to invention of Claim 7 and 8, the apparatus suitable for the combustion method of the pellet charcoal of Claims 1-4 can be provided.

The fuel cradle has an opening at the upper end. Is fitted in the upper end opening of a container-type combustion support base, and ignites the pellet carbide of the fuel cradle, takes air from the air intake port of the combustion support pedestal, and burns the receiving frame with the pellet carbide The object was heated or baked, and a combustion method using pellet charcoal was used.

Meats can leave fat and be separated, which is different from traditional yakiniku with a lot of smoke.

In the case of vegetables, root vegetables such as potatoes, sweet potatoes, and taros can be protected by covering them with aluminum foil or a lid, or sliced thickly and baked. Cook. Green vegetable vegetables contain a lot of moisture, so when finished in 3 to 6 minutes, the crunchy texture is good and you can cook without losing the umami and nutrients.

From cooking using raw materials such as low-temperature cooking at 60 ° C to 100 ° C, medium-temperature cooking at 100 ° C to 180 ° C, and medium-high temperature cooking at 180 ° C to 350 ° C.
