First, in the configuration of the baking kiln using the ACL block and the loess, the ALC block 110 having a size of 150 mm in width, 100 mm in length, and 300 mm in length is cut in half and polished into a wedge shape. This is because the ALC block 110 cut in half and wedge shaped is used to fabricate a round shape kiln which requires about 200 pieces.

Next, the loess 200 is evenly coated on the steel pedestal 120 and then dried. Preferably, a support 121 having a height of about 10 cm is installed at the lower end of the steel pedestal 120 for convenience of transportation Accordingly, when the kiln is moved by about 1.5 tons, it can be easily lifted by using a crane or the like.

The iron base 120 has a diameter of about 900 mm and is dried on the upper surface of the iron base 120 with a roughly 30 mm thickness of loess 200. The top surface of the loess loess 200 is covered with iron The ALC block 110 is stacked at a height of about 200 mm on the upper side of the iron furnace 130 to be assembled,

A plurality of cutouts 141 spaced from each other in a comb-like pattern are formed on the surface of the furnace plate 140. The furnace plate 140 is approximately 15 mm in diameter and 600 mm in diameter, . This is because when the charcoal 180 is heated by the furnace plate 140, the powder of the charcoal 180 is allowed to escape through the cutout 141 of the furnace plate 140, So that the amount of heat of the char 180 can be adjusted while the air is moved through the cutout 141 when the air hole 131 of the iron furnace 130 is adjusted.

Next, the ALC block 110 is mounted in a multi-stage structure with a height of approximately 400 mm to form a cylindrical shape. Then, the ALC block 110 is ring-shaped on the assembled ALC block 110 and has an outer diameter of 950 mm and an inner diameter of 750 mm. 151, the inner and outer surfaces of the assembled ALC block 110 are filled with yellow clay, and then the ALC block 110 is elevated to a height of 600 mm so that the inner diameter of the ALC block 110 is 600 mm. And the skewer stand 160 is installed on the assembled ALC block 110.

Therefore, a groove 161 is formed along the inner circumferential surface of the skewer holder 160 so that the grip portion of the skewer (not shown) can be mounted, and the lower end of the skewer is fixed to the engaging jaw 151 of the middle holder 150 Accordingly, the lower end of the shark catches against the inner surface of the assembled ALC block to prevent the loess of the loess adhering to the inner surface of the ALC block, and also prevents the floating shark floating.

Here, when meat is put on the shark's head, it is preferable that the meat is positioned at a position of about 600 to 800 mm above the burning plate 140 on which the charcoal 180 is placed. When the lid of the kiln is opened and the roasted meat is taken out while being separated from the charcoal 180, the air that has been blocked flows into the inside of the kiln to activate the flame to prevent the meat from burning and burning.

Next, a ring-shaped circular plate 170 having a rough outer diameter of 1000 mm and an inner diameter of 600 mm is placed on the top of the assembled ALC block 110, And the mortar body 100 is formed by repeatedly applying and drying the loess 200 on the inner and outer sides approximately once every 25 hours for about 2 hours to increase the tension of the kiln body 100 as much as possible.

In this case, the circular plate 170 installed at the upper end of the ALC block 110 is preferably made of marble or granite. For example, C black marble may be made of the same material as C black marble, The convection phenomenon of the heat inside the kiln body 100 can be effectively maintained by preventing it from being lost to the upper side of the furnace body 100.

Also, when the meat cooked in the inside of the kiln body 100 is taken out, the oil of the meat is prevented from falling into the top of the kiln body 100 to prevent the oil from penetrating into the inside of the kiln body 100, It is possible to prevent the phenomenon of being split by the infiltrated meat oil.

On the other hand, it is preferable that a temperature sensor 300 is installed on one side of the kiln body 100 to measure the internal temperature of the kiln body 100.

This is to control the meat because the meat can be baked in a heat source of about 400 DEG C to obtain the best taste. When the meat is higher than 400 DEG C, the air hole 131 of the iron oven 130 is closed to cut off the supply of oxygen , And when the temperature is lower than 400 ° C., the air holes 131 of the iron furnace 130 are opened to smoothly supply the oxygen, so that the thermal power of the charcoal 180 can be further strengthened.

The upper end of the circular plate 170 may be detached or hinged to one side of the circular plate 170 to provide a lid (not shown) so as to open and close the open portion of the circular plate, So that foreign matter can be prevented from flowing into the inside of the kiln body 100 during storage or transportation of the kiln body 100. [

In the meantime, according to the present invention, when the internal temperature of the kiln body 100 reaches approximately 400 ° C through the combination of the ALC block 110 constituting the kiln body 100, the clay loom 200 and the charcoal 180, So that the smell of the meat roasted in the kiln body 100 can be effectively removed and the meat quality can be softened.

In addition, the charcoal 180 is charged only once per 24 hours, no separate cleaning is required, and the material at the bottom of the furnace plate 140 can be used semi-permanently since it is only removed about 30% every three days. And management can be easily performed, and labor costs can be saved.

FIG. 7 is a block diagram illustrating a manufacturing process of a baking kiln according to the present invention. Referring to FIG. 7, an ALC block 110 having a predetermined size is cut in half and then cut into a wedge shape and cut into a wedge- A first step of applying a vegetable paste to the surface of the block 110 and drying the same; a step of applying yellow clay (200) at a predetermined thickness on a disk-shaped iron base (120) And a second step of mounting the furnace 130.

In the second process, it is preferable that the iron furnace 130 is formed in a wedge shape corresponding to the wedge-shaped ALC block 110 in a half-cut state, The front surface of the iron furnace 130 is placed in the same or protruding state as the outer edge of the iron base 120. In this case,

And a third step of cutting the wedge-shaped ALC block 110 to a predetermined portion and mounting the pre-blinds and the fired plate 140.

In the third step, a plurality of ALC blocks 110 are joined to each other along the outer edge of the steel pedestal 120 with the steel burner 130 as a center, so that the steel burner 130 and the ALC blocks 110 And then the yellow iron (200) is plastered on the upper side of the iron furnace (130) and the ALC block (110) in a circle, and then the other ALC blocks (110) And the ALC blocks 110 are alternately stacked in multi-stages with the loess 200 in such a manner that the loess loom 200 is laid over it.

And a fourth step in which the ALC block 110 is further rounded to have a predetermined height, and then an intermediate holder 150 and a skewer holder 160 are installed.

Preferably, the fourth step further includes a fifth step of mounting a ring-shaped circular plate 170, which is made of marble or granite and has a central through hole, to the upper end of the assembled ALC block 110.

In addition, by repeatedly applying and drying the loess 200 200 times in an interval of 2 hours, the loess 200 is repeated 25 times along the inner and outer surfaces of the assembled ALC block 110 in order to maximize the tension of the kiln body 100 .

It is preferable that the finished kiln body 100 is formed to have a height of 1400 mm, a thickness of 260 mm, a circumference of 4000 mm and a weight of 2.5 ton. When the kiln body 100 is manufactured, You can decorate it with a circular ring (190) to make you feel the beauty of oriental Korea.

When the kiln body 100 is manufactured as described above, the meat can be burned by the convection heat and radiant heat of 95% or more, so that the meat can be burned and the juice can be left intact.

It is generally known that it is best to taste meat at about 400 ℃, and that is why the meat is delicious when it is cooked on charcoal fire. However, in the case of charcoal, it is temporarily maintaining a heat source of about 400 ° C, and after the passage of time, 400 ° C can not be maintained continuously unless charcoal is added.

On the other hand, since the baking kiln according to the present invention uses a method of confining heat supplied from the bottom to the top, the internal temperature of the kiln continuously maintains 400 ° C., and the efficiency of roasting is improved as the meat is baked under these conditions It can be a juicy grill.

Meanwhile, the ALC block 110 serving as a mold of the kiln body 100 is made of ALC (Autoclacve Lightweight Concrete) in the form of a block having a rectangular hexahedron shape, wherein ALC means lime and silicic acid As a main material, it is a kind of concrete which is made by weightlessly dispersing innumerable bubbles in the inside by the foaming agent. Since this ALC block 110 has a light weight and a light weight of about 1/4 of ordinary concrete, Shortening the production cost and reducing the manufacturing cost due to an increase in work efficiency.

And 70% of the fine closed bubbles inside the ALC block 110 strongly block heat conduction and have an excellent heat insulating property ten times as much as that of ordinary concrete.

When one side of the ALC block 110 is heated for 120 minutes to reach 1010 占 폚, the backside rising temperature of T100 is 75 占 폚 and T200 is 18 占 폚, which is excellent in fire resistance. .

The ALC block 110 suppresses the generation of the spoilage bacteria due to the attraction force and can eliminate the source of the smell. The odor is applied to the ALC block 110 and the deodorization ratio is 95.7% after 2 hours, which is advantageous in that the deodorizing property is almost the same as that of charcoal.

In addition, the ALC block 110 prevents the propagation of bacteria by the far-infrared rays emitted by itself, and has an excellent antibacterial property that the bacterial reduction rate reaches 99.8% as a result of the antibacterial test by E. coli.

And ALC is legally acceptable for use as a plant fertilizer and feed additive in Korea and Japan.

In addition, the ALC has a far infrared ray emissivity of 91.2%, which activates cell tissue by generating 2000 wavelengths per minute, and a radiant energy of 3.68 x 100, which produces far infrared rays similar to that of elvan and charcoal.

The ALC block 110 includes 53 to 62% by weight of a silicious raw material, 17 to 28% by weight of cement, 12 to 27% by weight of powdered quicklime, a high or anhydrous 3 to 6% by weight of gypsum, and 0.04 to 0.1% by weight of an aluminum foaming agent.

53 to 62% by weight of the total solid content of the siliceous raw material is suitable. When the amount of the silicate raw material is less than 53% by weight, the amount of the unreacted siliceous raw material is decreased, and the bearing capacity of the tobermorite crystal formed on the surface of the siliceous raw material is weakened, Can be weakened. And when it is used in an amount of 62 wt% or more, the specific gravity is increased.

When the amount of cement is less than 17% by weight, scrap is generated due to insufficient bonding force at the time of curing. When the amount of cement is more than 28% by weight, the influence of magnesium oxide and the like contained in cement So that minute cracks are likely to occur.

The powdered quicklime is suitable as 12 to 27% by weight of the total solid content. Powdered quicklime is powdery and small in particle size. The higher the calcium oxide content, the faster the digestion rate and the larger the heat of digestion. The productivity of the ALC block 110 and the formation of the tobermorite can be facilitated.

The high or anhydrite gypsum suitably contains 3 to 6% by weight of the total solid content. Such anisotropic gypsum or anhydrous gypsum increases the wet strength of the ALC block 110 due to the intergranular filling effect, And the drying shrinkage rate is also decreased. However, if the amount of the high or anhydrous gypsum used exceeds 6% by weight, there is a risk of corrosion of the autoclave due to the influence of the water-soluble sulfate, and if the amount is less than 3% by weight, I can not.

Since the aluminum foaming agent determines the amount and size of bubbles in the ALC block 110, it is preferable to add 0.04 to 0.1 wt% of the total solid content. The aluminum foaming agent can be used in powder form, but the foaming rate can be easily controlled, The paste may be replaced with a pasty aluminum paste in which the aluminum raw material of the peeling structure is mixed with glycol or the like so that the dispersibility of the bubbles can be made uniform by improving the dispersibility.

When 0.6 to 0.8 times water is added to the total solids of the silicious raw material, the cement, the powdered quicklime, the anhydrous gypsum or anhydrous gypsum, and the aluminum foaming agent, the mixture is mixed and slurried. When the water content exceeds 0.8, The time is increased, and when it is less than 0.6 times, the bubbles generated due to the high viscosity become large, and cracks may occur on the surface of the slurry prior to the autoclave curing.

The mixed slurried mixture is cured at 180 ° C and 10 atmospheres for 6 hours by using an ordinary autoclave device to obtain an ALC block 110 in which bubbles are uniformly contained in a large amount.

On the other hand, in order to bake meat with convection heat, there is no crack or the like inside and outside the kiln body 100. If a crack is generated, the heat escapes from the kiln body 100 and the convection heat can not flow in a certain direction, and the meat can not be cooked at a predetermined time.

Therefore, as described above, the loess 200 is applied to the upper surface of the steel pedestal 120 of the kiln body 100, between the ends of the ALC block 110 and the inner and outer surfaces of the kiln body 100 It is preferable that the loess material 200 used is a mixture of loess and ceramics mixed at a ratio of 3: 4: 7 to 6, since the loess material 200 may cause shrinkage depending on the presence or absence of moisture when the loess material is used. .

In addition, by repeating the above-mentioned blending and drying of the yellow clay mixture on the inner and outer surfaces of the kiln body 100, cracks are split between the inside and the outside of the kiln body 100 and the convection heat can not flow in a certain direction So as to prevent the refraction phenomenon.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims and equivalents thereof.
