Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial charcoal,

More particularly, the present invention relates to a method for manufacturing an environmentally friendly artificial charcoal, and more particularly, to a method for manufacturing an environmentally friendly artificial charcoal which is capable of rapid ignition, preventing the smell and dust generated when the residual noxious gas is burned from being scattered, The present invention relates to an eco-friendly artificial charcoal manufacturing method and an eco-friendly artificial charcoal which prevent a safety accident such as a burn on the skin from occurring and increase a heating value by increasing hot strength.

Generally, in the case of a hot coal used for charcoal grilling in a restaurant or the like, it must be ignited from the outside and be ignited to a certain degree and then transferred to the room, so it is necessary to provide a separate ignition facility in the external space, In addition, there is a problem that the user avoids the ignition operation due to the toxic gas generated at this time, and research has been conducted to improve the ignition property for instant ignition. However, due to the risk of harming the environment due to the use of chemical substances, it has been used as a small amount of specialized product mainly for convenience such as the use of charcoal for outdoor barbecue due to deterioration of health and cost increase due to deterioration of health and many additives, It is difficult to use natural charcoal or thermal coal which is used in large quantities in large quantities in consideration of environmental friendliness and low cost practicality.

In the case of solid fuels used for charcoal grilling, natural charcoal of oak is considered to be the best, but as mentioned above, there is a disadvantage that the price is high. In most foodservice businesses currently being used in large quantities, it is the most widely available light coal that can be ignited instantly by adding potato chemicals such as barium nitrate, sodium nitrate, etc. to charcoal and wood powder, .

In addition, it has been pointed out that there is a problem in detection of harmful components such as barium and zinc in the case of roasted roast, the problem of the risk due to the carcinogenic substances such as benzopyrene, and the increase in the production cost. However, in the case of most of the businesses using solid fuels for charcoal grilling at present, priority is given to economical efficiency rather than convenience, and there is still a case where the wood flour Is the highest in the utilization rate of carbonized carbon.

However, most of the charcoal grilles used in the businesses are dependent on imports due to economic problems such as raw material supply problems and manufacturing cost, but there was a problem about re-scattering and burning persistence when using coal.

On the other hand, in the case of coal, since sulfur dioxide is generated at the time of combustion and the characteristic of coal is good, combustion persistence is good but it is difficult to ignite. Therefore, there are many difficulties to utilize as fuel for charcoal grilling. .

Natural charcoal of oak used for charcoal grilling generally is evaluated as the best. However, as pointed out above, in addition to a great disadvantage that price is high, natural charcoal is completely carbonized because it undergoes a primary carbonization process The smell and dust generated by burning the residual noxious gas are scattered or scattered, and the sealed indoor space is smudged, and the fireworks are scattered sporadically. It is pointed out that it is a factor that impedes the creation of a clean and clean environment which is a cause of customer 's service improvement.

  BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a step of manufacturing artificial charcoal according to the present invention; FIG.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For the sake of convenience, the size, line thickness, and the like of the components shown in the drawings referenced in the description of the present invention may be exaggerated somewhat. The terms used in the description of the present invention are defined in consideration of the functions of the present invention, and thus may be changed depending on the user, the intention of the operator, customs, and the like. Therefore, the definition of this term should be based on the contents of this specification as a whole.

Generally, when a tree is lit, the tree is divided into three types by pyrolysis, which is in the form of gaseous noxious gas, liquid wood vinegar and wood tar, and solid char, and finally remains in the form of charcoal. The charcoal according to the kind of material can be divided into charcoal carbonized by wood, carbonized by squeezing sawdust, and charcoal (for example, coconut, palm, walnut, pine nut, etc.) .

The baking temperature of the char is generally 400 ° C. to 1,300 ° C., and the baked at about 400 ° C. is called the honey, and the ovary of the honey is represented by the acidic pH, which is mainly used for cultivating horticultural crops. After baking at about 600 ° C, it cut off the outside air and produced fire extinguishing. The pH of black coal is slightly acidic at 6.5, and the burned coal is baked at 1000 ° C and the pH of the burned coal is weakly alkaline at 7.5. Black coal is widely used in filtration equipment, and the white coal is often used for fuel. The charcoal of the above-mentioned wood charcoal is obtained by refining oak at 600 to 700 ° C and then putting it in a kiln for 2 to 3 days. The removed oven is called black coal, refined at a temperature of about 1000 ° C, It is called as a flame-blanket in which the blended flame is covered and the flame is turned off at a rapid rate.

In recent years, it has been reported that charcoal has a characteristic of porosity (about 300 square per gram), an anion generation amount, and a rich mineral (about 80% carbonaceous material and the remaining minerals) Report).

In terms of strength, the bullet burns when it is knocked out, and the use of the bullet is higher because the black coal is crushed with a blunt sound. Black coal is a charcoal that can be made by anyone, but it requires a high level of skill and patience, and is superior in firepower than ordinary charcoal.

Charcoal produces about 4 times more infrared rays than gas fire, and most of them are far infrared rays. Since the infrared ray, which is radiant heat, goes straight, the surface of the meat is baked quickly and uniformly regardless of the wind, and the flavor is not lost, and the 'near infrared rays' having a short wavelength emitted from the charcoal are penetrated into the meat.

Therefore, consumers prefer to use a charcoal grill because they can browse on the outside and softly grill the inside, which is superior to the grilled meat or the grilled meat.

Accordingly, the charcoal made of wood, sawdust, and fruit husks contains a noxious gas such as a noxious gas such as nitrous oxide (N2O), which is subjected to a primary carbonization process in an unburned atmosphere, and has a hot strength, Is generally kept constant, but it is known that the carbonization degree is unstable due to the change of the thickness of the char, and the characteristics thereof are deteriorated.

When carbonized materials such as wood are carbonized, the amount of combustibles decreases as the carbonization temperature rises. However, as the carbonization temperature is about 450 ° C, the amount of heat generated per 1 kg of fuel is hardly reduced.

This is because, in the temperature range up to about 450 ° C, the rate of oxygen reduction is low in the combustible components and the ratio of carbon that increases the heating value is relatively high. As a result of the experiment, it was found that the calorific value of low temperature carbonization was about 4 times higher than that of high temperature carbonization and twice as much as that of medium temperature carbonization.

For this reason, the present invention has been carried out in consideration of the temperature of the carbonization type in which the emission amount of the harmful gas is much reduced and the calorific value is increased.

In addition, in the case of a conventional method for manufacturing a charcoal used as artificial charcoal, any one of charcoal powder produced in a general char manufacturing process and charcoal powder subjected to a pulverizing process may be selected and mixed with an adhesive (e.g., starch, However, the artificial charcoal which has been artificially bonded by the manufacturing process has been heated to a temperature higher than that of natural char, When the burning temperature is very low, when the burning is continued for a certain period of time after the burning, the shape of the artificial charcoal is changed into ash so that it is re-scattered and the amount of heat generation is small and the noxious gas and smoke And it is difficult to use it as fuel for roasting meat because it is low in complexity.

Accordingly, the present invention has been researched in consideration of the problems of artificial charcoal as described above. The sugar and sodium silicate, which have a role of adhering to charcoal powder produced by primary carbonization of a plant or a shell, It is an artificially processed charcoal that has undergone carburization and cooling process, but it has been researching and developing the combustion, ignitability, hot strength, harmlessness and convenience of human body by substituting natural charcoal function.

The present invention is able to ignite more rapidly than conventional activated carbon, thermal coal, and other artificial charcoal such as the above, and prevent burning of the skin due to spontaneous splashing during fuel heating to prevent safety, The natural charcoal of the present invention carries out the carbonization process for the first time. Therefore, it is possible to prevent the smell generated when the remaining noxious gas is burned and the scattering or scattering of the dust, By improving the customer service by the composition, it is also possible to develop the alternative artificial charcoal which is the same as the natural carbon burner through the secondary carbonization process, and the complete combustion is performed to improve the calorific value, to improve the combustion sustainability and the ignition property, It improves hot strength and makes it possible to sell at a lower price than natural charcoal, It is intended to be used as a personal product.

According to another aspect of the present invention, there is provided a method for manufacturing eco-friendly artificial char, comprising the steps of:

(S1) for sorting a charcoal powder having a particle size of 0.05 to 1 mm and a charcoal powder having a particle size of 0.1 mm to 0.3 mm at a ratio of 2: 1, wherein 13 to 23% by weight of molasses and 0.7 (S2) in which the charcoal powder of the above-mentioned sorting step (S1) is mixed in the amount of 2 wt% to 2 wt% in a cylindrical rotary mixer having a pressure of 1 to 2 kg / cm 2 at a temperature of 40 to 50 ° C. The more the amount of the charcoal powder is, the better the function of the charcoal is, so the better the performance of the charcoal. However, as the amount of the charcoal powder increases, the amount of molasses which acts as an adhesive increases, resulting in an increase in cost due to an increase in purchase cost. The amount of the charcoal powder to be added is preferably in the range of 70 to 85% by weight.

If the amount of the charcoal powder added is less than 70 wt%, the strength of the char solids produced may be weakened and the amount of the charcoal powder added may be reduced to the range of 70 to 85 wt%.

(S3) in which the raw material mixture in the mixing step (S2) is put in a vertical reciprocating molding machine to form a molding composition having a compression force of 1 kg / cm2 to 30 kg / (S4) in which the compression molded product of step (S3) is charged into a horizontal kiln and maintained at a temperature of 450 to 600 DEG C for 30 minutes to 40 minutes, and the oxygen-occluding lid is heated to continue for 5 to 6 hours, The carbide of the step S4 is taken out from the horizontal kiln and subjected to a cooling step S5 in which the material is naturally cooled for 3 to 4 hours and the loss of fixed carbon and volatile components contained in the product cooled in the cooling step S5 (S6), which is packaged in an airtight packaging container to prevent moisture from being absorbed, and at the same time, weighing is carried out by weighing the scale, On the method Will.

 In other examples of the mixing step, the following mixing and aging steps can be added or replaced.

The molasses in the mixing step is mixed with 20-25% by weight of sodium silicate and 0.7-1% by weight of sodium silicate, and the mixture is heated to a temperature of 40-50 ° C and a pressure of 1-2 kg / (S2 ') in which the mixture is aged for 10 to 20 minutes, thereby improving the quality of the product and satisfying the degree of mixing.

The compression molded product of the carbonization step S4 is subjected to a first preheating carbonization step S4 'in which the preform is preliminarily preheated at a temperature of 30 to 50 ° C and charged into a horizontal kiln in consideration of deformation before charging into a horizontal kiln .

The molding process of the compression molding step S3 includes a molding automatic control step S3 'for automatically controlling the molding of the mixture by pressing and kneading the mixture and discharging the mixture to reduce the intensity of the labor by the automatic control And is used as a measure to reduce the cost by improving the productivity in a large amount.

The eco-friendly artificial charcoal comprises the steps of: (S1) sorting the charcoal powder as described above; (b) mixing the mixture of molasses and sulphate with the selected charcoal powder; and (c) Cooling step, and packaging and shipping steps.

It is preferable that the molding die forming mold of the compression molding step is constituted by an upper molding die and a lower molding die, the upper molding die may be provided with a heating means, and the lower molding die may be moved upward and downward by a press.

In the carbonization step, the heating temperature of the upper mold is maintained at the carbonization temperature, and it is preferable to maintain the temperature at 500 to 600 ° C.

If the carbonization temperature is less than 500 ° C, the carbonization time becomes too long to reduce the productivity. When the carbonization temperature exceeds 600 ° C, the energy consumption is large, which is uneconomical and the temperature is selected in consideration of the decrease in hot strength and heat generation.

If the cooling step is not performed in the cooling step, the surface of the char is burnt, and the degree of carbonization according to the thickness of the char is uneven and the characteristics of the char are deteriorated. In the carbonization process of the char, .

Accordingly, since the degree of carbonization is kept constant due to the cooling step, it is possible to manufacture artificial charcoal having excellent quality.
