DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas roasting machine,
More specifically, the present invention relates to a gas porcelain machine which always allows a strong and stable flame to directly act on foodstuffs, while preventing a gas outlet from being clogged by dripping juice from the foodstuffs.

[0002]

2. Description of the Related Art Conventionally, as a gas pottery machine for making pottery such as fish, meat, vegetables, etc., as described in Japanese Patent No. 2,534,485, a ceramic plate having an arch-shaped cross section is opposed to a gas jet port of a gas burner. There has been known a ceramic plate in which the broth soaked from food is prevented from adhering to the gas outlet by the ceramic plate.

[0003] However, in this gas roasting machine, since the ceramic plate disperses the flame injected from the gas outlet and reduces the momentum, the time required to obtain the roasted product becomes longer, and the heat efficiency is poor. there were. As a solution to this, a method is considered in which the flame is increased by increasing the gas injection amount so that the flame directly touches the food material. However, the flame that is split into ceramic plates and reaches the food is slowing down, so despite the large amount of gas used, it is important to reduce the time required for the material to become substantially porcelain. It was not an essential solution.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a gas jet by a broth dripped from food while constantly applying a strong and stable flame directly to the food. An object of the present invention is to provide a gas porcelain machine which is excellent in thermal efficiency and also prevents the outlet from being blocked.

[0005]

In order to achieve the above-mentioned object, a gas-fired machine according to the present invention is provided with gas burners having gas outlets on the upper and lower sides of a net on which food is placed, respectively, on the side facing the net. An inclined plate is provided between the gas burner and the net, obliquely crossing a perpendicular line dropped from the gas jet to the net, and guiding a flame jetted from the gas jet toward the net, and An air nozzle for performing air injection for forcibly directing the flame toward the net is provided at least near the gas burner above the net.

As described above, the gas ejection port of the gas burner is provided with the inclined plate obliquely crossing the exit side and the air nozzle is arranged at least in the vicinity of the gas burner above the net. The air jetted from the air nozzle directs the flame, which is going to reverse upward after jetting from the gas jet port, toward the net surface. A strong flame can be brought into direct contact with food on the surface to perform baking cooking with high thermal efficiency. In addition, since the broth which is dropped from the food is received so as not to enter the gas outlet, the gas outlet is not closed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a gas porcelain machine according to an embodiment of the present invention, and FIGS. 2 and 3 each show a detail of a portion near a gas burner in the gas porcelain machine in a partial cross section. It is. In this gas roasting machine, as shown in FIG. 1, a net 1 made of metal wire is formed in an endless belt shape, and the net 1 of the endless belt is wound between a driving wheel 11 and a driven wheel 12, and a motor When driven by 13, it rotates continuously. Endless belt net 1
Has a relationship in which the upper side and the lower side in the horizontal direction move in directions opposite to each other through the drive wheel 11 and the driven wheel 12, and the pulley 14a and the weight 1
4b, a tension maintaining mechanism 15 is attached to maintain a constant tension.

The net 1 moving on the upper side is a net surface on which food is placed. The starting end is the food receiving portion 17, and the end is the pottery take-out portion 18. A plurality of gas burners 2 and air nozzles 21 are arranged at regular intervals in an intermediate region between them with a mesh surface therebetween. A plurality of gas burners 3 are provided at a certain interval on the lower side. An exhaust hood 16 is provided above the intermediate area where the gas burners 2 and 3 are provided. The mesh 1 is knitted from a metal wire such as stainless steel, and the mesh is formed in such a size that the food does not fall and the flame injected from the lower gas burner 3 can sufficiently penetrate upward. I have.

Below the gas burners 2, 3 arranged in a row,
Drip pans 24, 24 are provided respectively. The drip pan 24 receives the drip generated when baking ingredients, and the drip is collected in a transport vehicle 25 and is collectively processed. Also, the cooked pottery
It is received by the pottery receiving device 26. A carrier, a conveyor, a container, or the like is used as the pottery receiving device 26.

As shown in FIGS. 1 and 2, a gas burner 2 provided above the net 1 extends a pipe 6 horizontally so as to be orthogonal to the moving direction of the net 1. A large number of gas ejection ports 4 are provided on the lower side opposite to the above, and an inclined plate 5 that extends obliquely outside the gas ejection ports 4 is fixed. The inclined plate 5 obliquely crosses a perpendicular line L vertically lowered from the gas ejection port 4 to the net 1. The pipe 6 is connected in a branch shape to a fuel gas supply pipe 19 provided along the moving direction of the net 1.

The air nozzles 21 are provided in pairs near the gas burners 2 and are connected to the air supply pipes 23 in a branch shape with the air injection ports 22 facing downward. . The air supply pipe 23 is provided to extend in parallel with the fuel gas supply pipe 19.

Gas burner 3 provided below net 1
As shown in FIGS. 1 and 3, similarly to the gas burner 2 on the upper side, a pipe 9 is horizontally extended so as to be orthogonal to the moving direction of the net 1, and the pipe 9 is disposed on the upper side facing the net 1. A large number of gas outlets 7 are provided, and an inclined plate 8 that extends obliquely outside the gas outlets 7 is fixed. Similarly to the inclined plate 5, the inclined plate 8 obliquely crosses a perpendicular line L vertically lowered from the gas outlet 7 to the net 1. The pipe 9 is connected in a branch shape to a fuel gas supply pipe 20 provided along the moving direction of the net 1.

The inclined plates 5 and 8 attached to the gas burners 2 and 3 are each made of a metal or ceramic rectangular flat plate, and one side in the longitudinal direction is fixed to the pipes 6 and 9 along the longitudinal direction. I have. The pipes 6 and 9 are also made of metal or ceramic, and their base ends are connected to the fuel gas supply pipes 19 and 20 and the other ends are closed. A mixed gas of fuel gas such as city gas and propane gas and air is supplied to the fuel gas supply pipes 19 and 20.

When the gas burners 2 and 3 configured as described above are ignited respectively, in the case of the gas burner 2 on the upper side,
When air is not jetted from the air nozzle 21, FIG.
As shown in the figure, the flame F blown downward from the gas outlet 4 collides with the inclined plate 5 and is guided obliquely downward along the slope, but a part of the flame is bent and inverted upward. Try to rise. However, when air is jetted from the air nozzle 21, as shown in FIG. 4, the jetted air A forcibly directs the flame F downward and increases the amount of contact with food on the net 1, thereby improving thermal efficiency. . In addition, since the gas combustion efficiency is improved by the supply of air A,
The number of gas burners 2 installed per unit length of the net 1 can be reduced, which can contribute to downsizing of the apparatus.

The amount of air injected from the air nozzle 21 is not particularly limited as long as it is an amount that generates a forcing force to direct the flame F downward. However, if the air injection amount is excessive, the flame F tends to disperse laterally, so it is desirable to appropriately adjust the air injection amount so as not to be excessive. In the case of the gas burner 3 arranged below the net 1, as shown in FIG. 3, after the flame F injected upward from the gas outlet 7 collides with the inclined plate 8, it is guided along the inclined surface. Therefore, it is sprayed so as to rise upward on the lower surface of the net 1 in a state where the diffusion is suppressed. Therefore, as in the case of the gas burner 2, the flame F is brought into direct contact with the foodstuffs on the net 1, so that the heat efficiency is high and a uniform baking treatment can be performed without substantially causing baking unevenness. it can.

The flame F injected from the gas burner 3 rises spontaneously, and the phenomenon that the flame F injected from the gas burner 2 does not reverse in the middle unlike the flame F injected from the gas burner 2 does not occur.
The air nozzle 21 attached to the above is not always necessary. However, in the present invention, it does not prevent the installation of the air nozzle with respect to the gas burner 3. Since the air is guided to the exhaust hood 16 so as not to leak to the outside, an operation and effect of maintaining a good working environment can be achieved.

The food baked by the flame emits broth, which drops toward the lower gas burner 3. However, the lower gas burner 3 is provided with an inclined plate 8 at an upper portion, and the inclined plate 8 receives the broth, so that the broth enters the gas outlet 7 to cause clogging or extinguish a flame. Does not cause any problems. The upper gas burner 2
When the gas burner 3 and the lower gas burner 3 are provided so as to face each other, the flame injected from the lower gas burner 3 raises the hot air together with the flame toward the upper gas burner 2. , The thermal efficiency can be improved so as not to hinder the combustion of the gas burner 2.

In the case of a gas roasting machine in which the net 1 is formed in the shape of an endless belt, if the foodstuffs are sequentially placed on the foodstuff receiving portion 17 at the upper starting end, the upper and lower both sides are moved while moving in the middle area. It is continuously burned by the gas burners 2 and 3 and finally can be sequentially taken out as a pottery from the pottery take-out portion 18 on the other end side. Therefore, a large amount of food can be cooked at a time, and the upper gas burner 2 and the lower gas burner 3 perform the baking process. be able to.
In addition, since it is not necessary to invert the food during baking, the food does not lose its shape easily caused by the inversion.

In the embodiment of FIG. 1, the lower gas burner 3
Are provided concentrated on the food receiving part 17 side, and the upper gas burner 2 is provided concentrated on the pottery take-out part 18 side.
It is not limited to this form, and may be changed according to the type of food as long as it is arranged vertically with the net 1 interposed therebetween. For example, the lower gas burners 3 and the upper gas burners 2 are alternately arranged. Is also good. To avoid exuding a large amount of broth during the baking process, such as meat, and to reduce the umami by dripping of the broth, first bake the lower side of the meat as shown in FIG. It is preferable to reduce drip.

In the present invention, the gas outlets 4 and 7 are generally circular holes, but may be slit-shaped openings in the longitudinal direction of the pipes 6 and 9. In general, the directions of the gas outlets 4 and 7 are substantially perpendicular to the surfaces of the pipes 6 and 9, but may be obliquely inclined. In addition, gas outlets 4,7
Is the shape, size,
The orientation and the like may be variously changed.

Further, the inclined plates 5 and 8 do not necessarily need to be fixed to the respective gas burners 2 and 3. For example, as shown in FIG. 6, the longitudinal end of the inclined plate 8 (5) is integrally fixed to the support frame 31, and the attached inclined plate 8 (5) is attached to the gas burner 3 (2) in the longitudinal direction. May be arranged along. Alternatively, as shown in FIG. 7, a hook 32 is attached to the inclined plate 8 (5), and the pipe 9 of the gas burner 3 (2) is connected through the hook 32.
You may make it attach to (6) detachably.

The pipes 6 and 9 of the gas burners 2 and 3 are connected to the fuel gas supply pipes 19 and 20 by connecting the base ends of the pipes 6 and 9 as shown in FIG. The ends or the middle of the two or three may be connected by a connecting pipe, and the connecting pipe may be connected to the fuel gas supply pipes 19 and 20. As a method of supplying the mixed gas from the fuel gas supply pipes 19 and 20 to the respective gas burners 2 and 3, mixing is performed by providing forced air pressure feeding means (not shown) such as a blower in the fuel gas supply pipes 19 and 20. The gas may be sent into the gas burners 2 and 3 at a high pressure so that the fire power of the flame rising from the gas ejection ports 4 and 7 may be increased.

[0023]

As described above, according to the gas sintering machine of the present invention, the gas ejection port of the gas burner is provided with the inclined plate obliquely crossing the exit side, and at least in the vicinity of the gas burner above the net. Since the air nozzles are located on the inclined plate, the inclined plate guides the flame ejected from the gas jet toward the net, and the air jetted from the air nozzle turns the flame that is going to reverse upward after jetting from the gas jet on the mesh surface. , It is possible to perform high-efficiency baking cooking by bringing a strong flame into direct contact with food on the net surface. In addition, since the broth which is dropped from the food is received so as not to enter the gas outlet, the gas outlet is not closed.
