The pipe burner 104 is provided so as to extend in the longitudinal direction of the frying pan 100.

(Problems to be solved by the invention) However, in the conventional apparatus, since the pipe burner 104 used as the heating means is a flame heating system by the linear flame 105, the bottom of the frying pan 100 is locally affected by the flame 105. As a result, the oil in the fryer 100 burns and deteriorates,
There was a problem that the quality of the fried food would deteriorate.

Further, in the pipe burner 104, since secondary air is required for combustion, it is necessary to provide an inlet 106 for the secondary air in the surrounding of the pipe burner 104, and the heat associated with the combustion causes this inlet 1
It will escape from 06 to the outside and the heating efficiency will decrease,
There is a problem that the environment around the device becomes high due to the heat escaping to the outside and the working environment is bad.

(Means for Solving Problems) The present invention has been made in order to solve the above-mentioned conventional problems. Therefore, in the present invention, one end is used as an input portion and the other end is discharged. In a frying pan, a transfer means provided in the frying pan from a charging part to a discharging part, and a heating means for heating the frying pan from below, wherein the heating means is a blast type. A plurality of blast type infrared burners are provided in the lower longitudinal direction of the frying pan together with an infrared burner, and the blast type infrared burners and the frying pan are spaced apart from each other by a distance between the blast type infrared burners. The narrow width portion formed so as to be narrower than the space is provided, and the exhaust groove communicating with the chimney is formed in the narrow width portion.

(Operation) In the present invention, since the blast type infrared burner which is the heating means is the all primary air type combustion system that does not require the secondary air, it is not necessary to provide an inlet for the secondary air and the combustion heat There is no escape to the outside.

Further, the blast type infrared burner is a radiant heating method in which the refractory is red-heated by the combustion heat of the blast flame and is heated by the heat rays emitted from the red-hot refractory, so that it can be heated by hot air. Since the heating spreads radially, uniform heating can be performed.

Further, in the present invention, the heating means is formed by a blast type infrared burner, and a plurality of the blast type infrared burners are arranged in the longitudinal direction below the frying pan. Since the narrow part is formed so that the interval is narrower than the interval between the blast type infrared burner and the frying pan, and the exhaust groove communicating with the chimney is formed in the narrow part, the combustion heat from the burner is used. Can flow into the narrow portion and uniformly and effectively heat the entire bottom surface of the frying pan.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 and FIG. 2 show an automatic frying device A of this embodiment. This automatic frying device A comprises a frying pan 1, a feeding conveyor 2 and a pressing conveyor 3 as a transfer means, and a heating means. The blast type infrared burner 4 is used as a main component.

The frying pan 1 is formed in a long oil tank structure in which one end side is a charging section 11 and the other end side is a discharging section 12, and is supported by a machine frame 9.

The feeding conveyor 2 and the pressing conveyor 3 are means for transferring fried food (for example, tempura), and net conveyors are used for each. The feeding conveyor 2 runs along the bottom of the frying pan 1 from the charging section 11 to the discharging section 12. Is provided over the entire length up to and the holding conveyor 3 is provided with an oil level level 8 in the fryer 1.
Input section 11 and discharge section 12 so that they are located slightly below
It is provided from the middle part to the discharge part 12.

Therefore, when the raw material is fed from the feeding section 11, the raw material is initially sunk in oil and is therefore transferred at the starting end side of the feed conveyor 2, and gradually lifts up as the frying condition progresses during the transfer, and then the lifting conveyor. 3 and finally, in a fully fried state, the feed conveyor 2
It will be discharged from the discharge part 12 at the terminal end side of.

The blast-type infrared burner 4 serving as a heating means has a total of 6 positions, two positions in the width direction, at each position of the input part 11, the discharge part 12, and the intermediate part between the input part 11 and the discharge part 12 of the pan 1. In this case, a combustion chamber 7 surrounded by a heat insulating material is formed in the bottom and back of the frying pan 1, and in this combustion chamber 7, a burner installation portion 71 is provided.
Is narrowed, and the space between the burner installation parts 71, 71 rises so that the space between the burner installation part 71 and the bottom plate of the frying pan 1 is narrower than the space between the burner installation part 71 and the bottom plate of the pan 1. Part 72
Is provided, and an exhaust groove 74 communicating with the chimney 73 is formed substantially in the center of the narrow portion 72.

Further, as shown in FIG. 3, the burner 4 is provided with a cup 41 made of ceramic fiber and a tip 42 for blowing out a gas / air mixture (blast), and the cup 41 has a large number of annular step portions 43. A substantially spherical concave portion 44 having is formed on the upper surface,
The chip 42 is set at the center bottom of the recess 44, and
This is an all-primary air combustion method in which the air-fuel mixture is blown from the air outlet 45 provided in the tip 42 along the surface of the recessed portion 44 and is burned, and the surface of the recessed portion 44 is red-heated by the combustion heat. A radiant heating system is used in which the heat rays radiated from the recesses 44 are used for heating.

Therefore, in the automatic fryer apparatus A of the present embodiment, the combustion method uses the all-primary-air type blast-type infrared burner 4 as a heating means, so that it is not necessary to take in secondary air, and an air inlet is provided in the combustion chamber 7. Since it is not necessary to open it, it is possible to prevent the combustion heat from escaping to the outside.

Further, since the heating method is a radiant heating method in which heating is performed with a hot wire, it is possible to prevent uneven heating by hot air-like and radially spreading heating.

Further, since the narrow portion 72 is formed between the burners 4, 4 of the combustion chamber 7 and the exhaust groove is formed in the narrow portion 72, the combustion heat from the burner 4 causes the width between the burners 4, 4 to be large. It is possible to effectively and uniformly heat the whole bottom plate of the frying pan 1 by flowing into the narrow portion 72.

The present invention is not limited to the above-described embodiments, and for example, the rotary blades mentioned in the prior art may be used as the transfer means.

Also, the number of burners and the installation positions are appropriately determined in consideration of the length and width of the frying pan.

The material used for the burner cup is not limited as long as it has high radiation ability, durability, low specific heat, low thermal conductivity, etc. It is possible to use a certain material, for example, a heat-resistant alloy such as nickel-chromium steel or ceramic.

By storing water in the fryer, it can be used as it is as an automatic fryer device.

(Effect of the Invention) As described above, in the automatic fryer device of the present invention, since the blast type infrared burner is used as the heating means, the combustion system is the all primary air system, and as a result, the secondary air system is used. Since the intake port is not needed, the combustion heat does not escape, the heating efficiency is improved, and the temperature rise around the device is eliminated, and the working environment is improved.

Also, since the heating method is a radiant heating method, unlike local heating such as conventional flame heating, uniform heating can be performed, and it is possible to prevent problems such as oil burning and deterioration.
The effect of improving the quality of fried food is obtained.

Further, in the present invention, the heating means is formed by a blast type infrared burner, and a plurality of the blast type infrared burners are arranged in the longitudinal direction below the frying pan. Since the narrow part is formed so that the interval is narrower than the interval between the blast type infrared burner and the frying pan, and the exhaust groove communicating with the chimney is formed in the narrow part, the combustion heat from the burner is used. Can flow into the narrow portion and uniformly and effectively heat the entire bottom surface of the frying pan.
