The present invention relates to a method for producing charcoal molded article having low manufacturing cost.
It is estimated that carbonization began about 5,000 years ago, and along with the development of the industry, the carbonization industry of wood has also developed remarkably. Carbonization of wood refers to chemical changes that thermally decompose various organic compounds that make up wood into other materials. Carbonization of wood can be divided into two types: coal and dry.
At this time, the application of the main purpose of the production of charcoal is called coal and the case of the main purpose of the production of liquid product is called dry distillation.
In the case of peat, raw materials are used as raw materials, and kilns are used. In the case of dry matter, mainly dry materials are used as raw materials. Usually, distillers are used.
Specific methods of the coal making mainly intended for the production of charcoal include a flat coal milling method, an intragranular coal milling method, a deposition coal milling method, and a shaft mill coal milling method. Among these, the potter's wheel making method has been used in Korea, Japan, and China for a long time, and carbonizes wood by constructing a kiln with earth, lead, refractory brick, insulation cement, concrete, and iron plate. You can make
The charcoal thus produced has conventionally been mainly used as a base material for various fuels, but recently, it is widely used as a main fuel for grilling meat in restaurants and the like with the improvement of living standards. In general, gas fires and charcoal fires have been mainly used as fuels for grilling meat, and in terms of convenience, the use of charcoal fires has been greatly increased in response to the desire of consumers to enjoy a taste close to nature although gas fires are relatively superior.
Recently, efforts have been made to further improve the function of charcoal. For example, hot coal and shaping charcoal using sawdust, bark, chaff, etc. are manufactured and used as a charcoal roast fuel in homes or restaurants. Molded charcoal is carbonized from sawdust, rice husk, bark powder, etc., dried to 10% or less of moisture, and then molded and heated with a molding machine to form hexagonal or octagonal with a hole in the center. Molded charcoal is suitable for cooking fuels and household fuels, and it is also used as a raw material of carbon disulfide for industrial purposes.
