Description

Rotary barbecue device using catalyst burner {Rotary barbecue device by catalyst bunner}

The present invention relates to a rotary barbecue apparatus using a catalytic burner (catalyst combustion burner), and in particular, chicken, duck, pig, chlorine, as a heat source of a flameless catalyst burner having high energy use efficiency and a large amount of infrared radiation (emission). Various meats (meat) such as sheep and cattle can be directly heated to be cooked from the inside, improving the taste and quality of these meats, and relatively short time, unlike conventional barbecue devices where the surface of meat is over-dried due to prolonged heating. The meat will be cooked.

Barbecue cuisine is one of the traditional dishes that have been enjoyed in both East and West. As the dietary life develops, the cooking (cooking) methods and cooking utensils are steadily developing.

The conventional barbecue apparatus mainly uses an indirect heating method in which an electric heat heater is built to bake meat and burn it by burning charcoal or wood fire, or burn it by heat, or raise the room temperature of the roasting chamber with a burning flame of LPG.

In addition, the heat transfer method using an indirect heat source has a problem that the surface of the meat (meat) is often dried because the heat generation amount is low and the heating is performed for a long time, and the quality of the product is deteriorated. It takes a lot of time and the life span of the electric heating rod is short, so it has to be replaced frequently.

In addition, charcoal or wood firewood is not unsanitary due to soot, smoke, etc., and the outside of the meat has a problem of less ripeness due to the inside of the ride, and the indirect heating method of heating by raising the room temperature with the flame of LPG gas. Its heat efficiency is lower than direct heating, and the temperature of the room is raised to bake meat at that temperature.

In addition, it is difficult to maintain a constant heating temperature of the meat, and the meat is heated from the surface of the meat no matter how well grilled, so if you wait until the inside of the meat is completely baked, the surface will not be overdried. In severe cases, the surface of the meat is pressed or burned, so the taste and quality were greatly reduced.

In addition, as the heating source adopts an indirect heating method using an electric heater with a high power consumption and a short lifespan, the maintenance cost is increased and the cumbersome time is required.

The rotary barbecue device has a door installed on one side of the hollow hollow barbecue device, and a rotating shaft which is decelerated and rotated horizontally by a motor and a power transmission means is installed inside the barbecue device, and both ends of the rotating shaft are provided. The rotating disk is installed, the inner surface of the rotating disk is provided with a plurality of hook pins that can hang the hook portion of the hanger facing each other, the hanger has an open (open type) basket form to hold the meat, rotating Even if the disc is rotated by the motor, the center of gravity is located at the bottom of the hanger, so it always rotates while maintaining the horizontal state.

The barbecue device configured as described above puts an appropriate amount of meat to be cooked in each hanger, then hangs the hanger part on the hanger pin of the rotating disc, and then turns on the motor power switch to turn the rotating disc. .

Therefore, the hanger caught in the rotating disc and the meat contained in the hanger are rotated in a horizontal state, so that the entire meat is exposed to the heating source and evenly baked. That is, the meat on the hanger is cooked uniformly because it is exposed to the rising heat source of the heating source, and the meat is baked evenly while rotating in the hanger so that the shape of the meat does not change.

However, this is also indirect heating method as described above, it is difficult to maintain a constant heating temperature of the meat, and even if grilled well while maintaining a constant temperature is heated from the surface of the meat when it is completely baked If you wait until the surface is not only dry, but in severe cases the surface of the meat is pressed or burned, there is a problem that the taste and quality are greatly reduced.

Meanwhile, the catalytic combustion burner equipped with a catalyst mat enables flameless combustion at a low temperature of 600 ° C. or lower by using a highly active catalyst that promotes the reaction of LPG or LNG fuel with oxygen. Since the combustion is complete without the flame generated by the surface reaction of the catalyst, pollution is prevented due to the improvement of the combustion rate, there is far infrared radiation effect, there is no flame (flame) and the temperature is low, there is no risk of fire, and the heating object There is an advantage that can be heated close to the surface of.

The catalytic combustion has a much wider heating range than conventional flame combustion, which enables the combustion of lean gases that cannot be burned by flame combustion, and burns fuel at low loads to achieve complete combustion, in particular combustion. Due to the low temperature, nitrogen oxides are not generated at all, and are being applied to various industrial fields.

The present invention uses a flameless catalyst burner that emits a large amount of far-infrared rays as a heat source of the barbecue device to solve the problems of the conventional barbecue device, so that various meats (meat) are cooked from the inside to taste and quality. It can be expected to improve, and by using the direct heat of flame-free, it aims to maximize the effect of barbecue in terms of heating temperature and efficiency.

In order to achieve the above object, a variety of meats (meat) such as chicken, duck, pig, goat, sheep, cow, etc. are installed by direct heating and far-infrared by installing a catalytic burner that generates direct combustion heat of far-infrared and flameless on the heating chamber side of hot bar roaster Heat evenly to bake.

The catalyst burner has a front structure, a catalyst mat, a ceramic thermal insulation material, and a rear network in a layer structure in a case in which a downward opening is formed, and a preheating heater connected to a controller is installed in the catalyst mat, and between the rear network and the case. A fuel retention space is formed in the casing, and a fuel supply pipe communicating with the fuel retention space is connected to one end of the case, and a fuel supply pipe is connected to an on / off valve controlled by a controller and a fuel supply source so that a large amount of far-infrared rays are emitted to flame-free combustion. It is.

Therefore, the wavelength of far-infrared rays emitted from the catalyst burner is radiated evenly to the meat to efficiently use energy, and the meat is cooked from the inside by the action of far-infrared, so that the meat to be grilled is roasted evenly without burning, so the meat is soft and tasty. It is possible to provide good roasting, and unlike the conventional barbecue device where the surface is overdried by a long heating, it can be sufficiently heated in a relatively short time so that the surface of the meat is not overdried or deteriorated in taste and quality.

In addition, since the use of clean fuel such as LPG or LNG can significantly reduce the fuel maintenance cost burden, soot, non-combustible gas (hazardous gas) and nitrogen oxides do not occur, it is hygienic.

In addition, the present invention has a drip phenomenon in which the surface of the protein is dried and discolored brown while carbon atoms, which are the nucleus of the protein, fly away with the water molecules when the protein is broken down due to a large amount of far-infrared radiation. Since it is suppressed, even if the heating time is sufficient, there is no problem that the meat (meat) is burned or excessively dried.

Hook pins 22 are installed to face each other.

The hanger 18 has an exposed (open) basket shape to hold the meat 4 and is bent and welded by a plurality of thin wires so as not to interfere with conduction and convection of heat and far infrared rays.

In addition, the hanger 20 is positioned at both upper sides of the hanger 18 so that the center of gravity of the hanger 18 is positioned below, so that the hanger 18 is always horizontal even when the hanger 18 is rotated along the rotating disc 16. It is possible to maintain, the body portion of the barbecue device 2 is configured by installing a catalyst burner 26 is exposed to the inside of the roasting chamber 6 as shown in FIG.

In addition, a temperature sensor 32 is installed at an inner upper portion of the roasting chamber 6 to sense an atmosphere temperature of the catalyst burner 18, the lamp 28, and the roasting chamber 6 and input it to the controller 30.

3 is a cross-sectional view of the catalyst burner 26 shown in one embodiment so that the present invention can be applied to the present invention. Looking at the configuration, the front mesh 38 and the catalyst are formed inside the case 36 in which the opening 34 is formed. The mat 40, the ceramic insulation 42, and the rear mesh 44 are installed in a layered structure.

The catalyst used in the catalyst mat 40 is a inorganic metal fibrous material carrying a noble metal or metal oxide catalyst, for example, porous alumina containing catalytically active metals such as platinum (Pt), palladium (Pd), rhodium (Rn), and the like. It is comprised by forming a fiber to an appropriate thickness.

The heat resistance temperature of the catalyst is maintained at a high specific surface area of the inorganic fibrous material, the maximum temperature of the catalyst layer is maintained within 600 ℃ to prevent volatilization or sintering of the catalyst supported on the fiber, and the combustion load is low, mainly indoor or factory It is used in low temperature drying or low temperature heating in heating or industrial process.

Meanwhile, the meshes 38 and 44 of the metal mesh function to enable efficient fuel supply and effective heat dissipation while maintaining the layer structure of the catalyst mat 40 and the ceramic thermal insulating material 42, and the ceramic thermal insulating material 42 is In addition to maintaining safety by preventing heat generated from the catalyst mat 40 from being transferred (conducted) to the rear surface, the feed fuel is distributed and supplied to the entire surface of the catalyst mat 40, and the catalyst mat 40 is kept at a constant temperature. It works so that it can be maintained.

In addition, a preheating heater 46 is installed inside the ceramic heat insulating material 42 to achieve initial ignition by heating the catalyst mat 40 to a temperature of about 200 ° C. or more, which is a catalyst reaction start temperature, and the preheating heater 46 is provided. It is connected to the controller 30 and is under its control.

That is, the controller 30 supplies the operating power to the preheating heater 46 at initial ignition to heat the catalyst mat 40 until the catalyst reaction start temperature is reached. After about 10 minutes, the controller 30 switches the gas opening and closing valve. The 48 is opened to supply fuel necessary for combustion to be ignited and then burned, and then to cut off the power supplied to the preheater 46.

A fuel retention space 50 is formed between the rear mesh 44 and the case 36, and a fuel supply pipe 52 communicating with the fuel retention space 50 is connected to one end of the case 36.

In the present invention, the supply or flow of the fuel is automatically controlled by the controller 30, the gas opening and closing valve 48, the fuel supply pipe 52 is supplied with LPG, LNG, etc. is not mixed with the combustion air is small in diameter .

In addition, an air supply hole 54 is formed at an upper portion, a lower portion, or an upper and lower portion of the catalyst mat 26, and the air required for combustion flows into the roasting chamber 6 through the air supply hole 54, and thus the catalyst burner 26. It is naturally diffused to the opening 34 of the), the gas supply valve 52 and the fuel supply source 56 under the control of the controller 30 is connected to the fuel supply pipe 52 of the catalyst burner 26.

In addition, a temperature sensor (or temperature switch) 32 connected to the controller 30 is installed inside the roasting chamber 6 so as to sense an internal temperature of the roasting chamber 6, and the controller 30 is initially set. During operation, the preheating heater 46 is disconnected or there is an abnormality, so that all operations are stopped and the safety of gas fuel is emphasized. In addition, it is preferable to perform automatic preheating and ignition by a one-touch button method.

In addition, a gas leakage detecting sensor 58 is installed in the interior or exterior of the roasting chamber 6 or an inner or outer bottom thereof, and then connected to the controller 30 to close the gas open / close valve 48 when gas leakage is detected. Enhance your safety by doing so.

In the present invention, the inner wall surface of the roasting chamber 6 and the inner wall surface of the transparent door 8 may be made of ceramic, pottery, or metal that emit far infrared rays, or by applying or attaching a plate-like far infrared radiator to the side wall of the heating chamber. Far-infrared radiation efficiency can be improved.

As the radiator emitting far-infrared rays, it may be possible to use a mixture of ganbanite powder, loess and stone powder such as vermiculite and talc in an appropriate ratio.

In the upper part of the roasting chamber 6, the lighting lamp 28 is installed in the position which is not caught when the hanger 18 hanged on the rotating disc 16 rotates.

The barbecue device 2 configured as described above evenly contains the appropriate amount of meat 4 to be cooked on the hanger 18, then opens the transparent door 8, and the hanger pin 22 installed on the inner side of the rotating disc 16. The hangers 20 of the hangers 18 are mounted on the hangers 20, respectively, and then the transparent doors 8 are closed.

Subsequently, after setting the appropriate temperature range and cooking time using the temperature control knob and the timer knob of the controller 30 according to the type of the meat 4, the catalyst burner 26 is operated by pressing the operation button. Will be baked for the set temperature and set time.

When the temperature rises above the set temperature due to the abnormal operation of the barbecue device 2, the temperature sensor 32 detects this and inputs the signal to the controller 30, and the controller 30 is set with the input signal. In consideration of the reference signal, the gas opening / closing valve 48 is interrupted so that the supply amount of SARS can be controlled to maintain the temperature of the catalyst burner 26 at the set temperature. In addition, when the internal temperature of the roasting chamber 6 is excessively increased, the gas opening and closing valve 48 is closed to shut off the gas supply and at the same time, an alarm is not shown.

As described above, the roast is baked for a predetermined time, and when the roasting time input by the timer 22 is reached, the operation of the catalyst burner 26 is stopped and the user is informed that the barbecue is completed.

Meanwhile, in order to operate the barbecue device 2, the controller 30 is supplied with power to the preheating heater 46 built in the catalyst burner 26 to the catalyst mat until the catalyst reaction start temperature reaches 200 ° C to 250 ° C. When the temperature of the catalyst mat 40 reaches the above temperature when the temperature of the catalyst mat 40 reaches the above temperature, the controller 30 opens the gas opening / closing valve 48 so that the fuel (LPG / LNG, etc.) of the fuel supply source 56 is connected to the fuel supply pipe ( 52), the fuel retention space 50, the rear mesh 44, and the ceramic insulating material 42 are sequentially supplied to the catalyst mat 40 heated at the reaction temperature and ignited, and then supplied to the air supply hole 54. As it reacts with air and burns in a flameless state, flameless heat and far-infrared rays are emitted, and thus normal combustion occurs, and power supplied to the preheating heater 46 by the controller 30 is cut off.

The surface temperature of the catalyst burner 26 reaches about 400 ° C by normal combustion, but overheating or overdrying of the meat 4 is prevented by the action of far infrared rays.

In addition, the barbecue device 2 of the present invention emits a large amount of far-infrared rays together with heat from the porous alumina fibers constituting the catalyst mat 40 during combustion, in which the catalyst mat 40 is roasted through the opening 34. Towards the hanger 18 of the yarn 6 and the meat 4 contained in the hanger, an abundant amount of far-infrared radiation released with heat acts as the meat 4 to be baked from the inside out.

At this time, the far infrared rays penetrate deeply inside the meat (4) to be cooked by self-heating, and wastes inside the meat (4) such as fat and cholesterol, which are harmful to the human body, are decomposed and discharged as oil. Roasted evenly to obtain a smooth and delicious meat (4).

In addition, when the catalyst burner 18 is burned, fuel and air are adsorbed on the catalyst surface, and an oxidation reaction occurs at the catalyst surface, resulting in a flameless combustion reaction, and the catalytic combustion has a much wider flammability range than that of conventional flame combustion. Is completely burned by burning a rare gas that is not combustible or burning a fuel at a low load. In particular, nitrogen oxides are not generated at all due to the low temperature of the combustion gas.

Therefore, the meat is ripened from the inside by the action of far-infrared rays emitted from the catalyst burner, so that the surface of the meat may be over-dried or taste and quality can be sufficiently heated in a relatively short time, unlike the conventional barbecue device where the surface is over-dried for a long time. This falling thing disappears.

In addition, since the use of clean fuel such as LPG or LNG can significantly reduce the fuel maintenance cost burden, soot, non-combustible gas (hazardous gas) and nitrogen oxides do not occur, it is hygienic.

In addition, the present invention uses the cheapest LPG / LNG fuel, and the infrared rays before and after 10 microns, which is the wavelength range of water molecules, are radiated (emitted and irradiated) by the catalytic burner, causing resonance and absorption. As the water molecules of the three layers forming the protein surface are activated, the intermediate binding force of the water molecules is increased and the drip phenomenon is suppressed.

The drip phenomenon means that when the water molecule bond of the protein surface is broken and the protein is decomposed, the carbon atom, which is the nucleus of the protein, flies together with the water molecule and the surface becomes dry and brown.

In addition, since the drip phenomenon is suppressed by far-infrared radiation, there is no problem that meat (meat) is burned or excessively dried even with sufficient heating time.

Reference numeral 60 is an oil sump, 62 is a gas outlet, 64 is a gas outlet, 66 is a handle, and 68 is a heat insulating material.

The present invention as described above is not limited to the present embodiment and the accompanying drawings, various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention, which is usually in the art It is self-evident for those who have knowledge.

As described above, the present invention is a barbecue of meat (meat) by the direct heating method of the catalytic burner which generates a large amount of far infrared rays, and thus has higher thermal energy and electric energy utilization efficiency than the indirect heating method by the conventional electric heater, and the action of far infrared rays. The meat is cooked while facing outwards, thereby preventing the surface overdrying of the meat, thereby improving taste and quality.

In addition, the present invention, the meat is roasted evenly and uniformly by the radiation of abundant far-infrared radiation together with the flameless heat, and the waste that is harmful to the human body is removed to taste more delicious and grilled meat, and even after it is baked, it is not pressed or overdried. It does not have the effect that you can eat while keeping it relaxed.

In addition, the present invention uses a flameless catalyst burner instead of a high-efficiency electrothermal heater with high power consumption, thereby reducing power consumption and minimizing the loss of meat from the meat surface by the action of far infrared rays.

In addition, the present invention, because the meat is continuously rotated by the rotating disk, the temperature is always maintained uniformly roasted uniformly without partial burning or undercooking, while the partial oxidation phenomenon that burns the contact part like the grill plate It is effective in disappearing.

In addition, the present design has the effect that it is possible to grill a high-quality barbecue without the generation of smoke while using a conventional heating device such as a gas burner or electric heater in the room.

In addition, the present invention has the effect of obtaining a chewy and delicious roast because the oil is removed by the action of far infrared rays and ripened while maintaining a certain amount of moisture.

In addition, the present invention has a drip phenomenon in which the surface of the protein dries and becomes brown while carbon atoms, which are the nucleus of the protein, fly away with the water molecules when the protein molecules are broken down by a large amount of far-infrared radiation. Since it is suppressed, even if the heating time is sufficient, there is an effect of eliminating the problem that the meat (meat) is burned or excessively dried.
