Description

[Detailed description of the invention] (Field of industrial application) The present invention is an automatic roasting machine in which an air-permeable conveyor for placing and transporting articles is installed inside a roasting chamber equipped with a heat source. In particular, the present invention relates to an automatic roasting machine that makes effective use of a heat source.

(Prior Art) In a conventional automatic roasting machine, heat sources are provided at predetermined intervals opposite the stay conveyor (see, for example, Japanese Utility Model Publication No. 57-53457).

(Problem to be solved by the invention) In the conventional automatic roasting machine, a space is provided between the heat sources, and a part of the heat inside the firing chamber is exhausted from the space between the heat sources. The problem was that the heat was discharged without being recovered, resulting in poor thermal efficiency.

In the present invention, between the first heat source and the second heat source,
The object of the present invention is to provide an automatic baking machine that eliminates the above-mentioned problems by providing a member that absorbs a portion of the heat from the heat source and emits radiant heat to the articles on the breathable conveyor.

(Means for Solving the Problems) In order to achieve the above object, in the automatic roasting machine of the present invention, at least a first heat source and a second heat source are provided, and heat from the heat sources is disposed between them. A member is provided that absorbs some of the heat and emits radiant heat to the articles on the breathable conveyor.

(Function) The automatic baking machine configured as described above absorbs a part of the heat from the heat source between the first heat source and the second heat source and emits radiant heat to the articles on the ventilation conveyor. The members recover heat and radiate the heat to the articles on the breathable conveyor.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 is an automatic grilling machine, in which a grilling chamber 2 is provided, and in the grilling chamber 2, fish (for example, sea bream), A breathable conveyor 4 is provided to transport goods 3 such as meat.

The breathable conveyor 4 is formed, for example, of a stay type, a net type, or the like.

Above the breathable conveyor 4, a first heat source 5 (for example, an infrared burner, a vacuum burner, etc.) and a second heat source 6 (for example, (burner, infrared burner, etc.) are provided alternately, and an automatic baking machine 1 is installed on the ventilation conveyor 4.
Exhaust hoods 12, 12 having exhaust ports 11, 11 are provided facing the breathable conveyor 4 from the center to the exit side.

Further, between the first heat source 5 and the second heat source 6, a part of the heat from the first heat source 5 and the second heat source 6 is absorbed and radiated heat is transferred to the articles 3 on the breathable conveyor 4. Each of the members 7, 7, .

The member 7 is, for example, a ceramic plate formed of ceramics with a honeycomb-like structure, and because it has a honeycomb-like structure, it can absorb waste heat and radiate it to the article 3 well. , the article 3 can be baked evenly.

Note that part of the heat from the first heat source 5 and the second heat source 6 passes through the member 7, and the exhaust temperature is
The temperature is about 200℃ to 500℃.

Since the member 7 is heated using this exhaust gas, energy saving can be achieved.

Furthermore, when ceramics are heated, far infrared rays are emitted, and far infrared rays in particular are well absorbed by food and excite food molecules, causing heat generation. Quality is improved because the surface can be heated evenly from the inside without being heated more than necessary.

If the member 7 is made of a ceramic plate as in this embodiment, the articles 3 on the breathable conveyor 4 can be baked well, and the ceramic plate has the effect of scientifically decomposing and oxidizing soot and odor. , pollution can also be prevented.

Further, a line burner 8 is installed below the ventilation conveyor 4 as a heat source from the entrance side to the exit side of the automatic roasting machine 1 so as to face the ventilation conveyor 4.
is provided.

Note that the ventilation conveyor 4 is driven by a drive motor 9 via sprockets 10, 10, . . . .

In the automatic grilling machine 1 having such a configuration, when an article 3 such as fish or meat is placed on a stay (other nets, etc.) not shown in the ventilation conveyor 4 at the starting end of the ventilation conveyor 4, the article 3 is sex conveyor 4
As a result, the article 3 is transferred between the first heat source 5, the second heat source 6, the member 7, and the line burner 8, and both sides of the article 3 are burned by fire heat, radiant heat, or the like.

At this time, the member 7 absorbs part of the heat from the first heat source 5 and the second heat source 6 (for example, the temperature of the exhaust gas passing through the member 7 is about 200°C to 500°C). It is possible to save energy by emitting radiant heat to the articles 3 on the breathable conveyor 4.

Further, since oil and the like falling from the article 3 fall into a water tray (not shown) provided under the breathable conveyor 4, soot and smoke can be prevented and the glossy finish of the article 3 can be improved.

Fig. 4 shows a reversing type in which the first and second ventilation conveyors 15 and 16 of upper and lower stages are combined in a single-sided baking method to automatically invert the article 3 and bake both sides of the article 3. This shows an example in which the present invention is applied to an automatic grilling machine 20 (for example, Japanese Utility Model Application Publication No. 49-49184) (the same reference numerals are given to the same parts as described above), and there are grilling chambers 2, 2 inside. is provided, and in the grilling chamber 2, as described above, articles 3, 3, etc. such as fish and meat are stored.
A first air permeable conveyor 15 and a second air permeable conveyor 16 (for example, stay, net type, etc.) for transporting... are provided.

Above the first breathable conveyor 15, a first heat source 5' (for example, an infrared burner) is installed as a heat source from the entrance side to the exit side of the automatic roasting machine 20 so as to face the first breathable conveyor 15. , a vacuum burner, etc.) and a second heat source 6' (for example, a vacuum burner, an infrared burner, etc.) are provided alternately. A first heat source 5'' (for example, an infrared burner, an infrared burner, etc.) and a second heat source 6'' (for example, an infrared burner, an infrared burner, etc.) are provided alternately so as to face each other.

Furthermore, between the first heat source 5' and the second heat source 6',
