(イ) 産業上の利用分野
この発明は、菓子・パン類焼成用トンネル窯に
関するものである。[Detailed Description of the Invention] (a) Industrial Application Field This invention relates to a tunnel kiln for baking confectionery and bread.
(ロ) 従来技術
従来、高級焼菓子、特にカステラの焼成には、
能率的はトンネル窯がすでに開発されているにも
かかわらず、固定窯が用いられている。(b) Prior art Conventionally, when baking high-grade baked confectionery, especially castella cakes,
Although tunnel kilns have already been developed for efficiency, fixed kilns are still used.

ず、被焼成物の表面が加熱され、同被焼成物内部
への加熱は熱伝導により行われている。 The reason is that conventional firing kilns use an electric resistance heating element or a gas burner as a heat source, and heating the object to be fired increases the internal atmosphere temperature of the kiln through convection, etc.
Heating is performed using near-infrared radiation emitted from the heating element, and ultraviolet radiation emitted from the flame in gas burners.In both heating methods, the surface of the object to be fired is first heated, and Heating inside is done by thermal conduction.

焼き上げるトンネル窯では、上記の泡切り及び灰
鉄板の作業が困難であるため、依然として固定窯
が使用されることになつていた。 On the other hand, castella dough, which is a material to be burned, is mainly made of starch, sugar, and water, and these materials have low thermal conductivity.Furthermore, since the dough is formed into a spongy shape, the heat conductivity of the dough is The rate is extremely low. For this reason, there is a large temperature difference between the surface and the inside of the object to be fired, resulting in the problem that the surface is overfired and the inside is unfired. The dough is stirred approximately four times in the early stages of baking to ensure a uniform temperature of the dough, and from the middle to late stages of baking, the dough is stirred on an iron plate filled with ash called a ash iron plate. In tunnel kilns, where the top surface is covered and the heating from above is partially cut off, it is difficult to perform the above-mentioned bubble removal and ash iron plate work in tunnel kilns, where the object is fired all the time. Therefore, fixed kilns were still to be used.
(ハ) 発明が解決しようとする問題点
しかしながら、固定窯ではいかにも非能率であ
り、泡切りの時期判断及び手技には格別の熟練を
要するものであり、灰鉄板作業も高温下で行われ

のであつた。(c) Problems to be solved by the invention However, fixed kilns are extremely inefficient, require special skill to judge when to remove bubbles, and require special skill, and ash iron plate work is also carried out at high temperatures. Therefore, the firing failure rate was extremely high.
なお、焼成温度を低めて緩徐な焼成により上記
欠点を回避しようとすれば、生地が乾燥しすぎて
カステラのしつとりとした風味が失われることに
なる。 If an attempt is made to avoid the above drawbacks by lowering the baking temperature and baking slowly, the dough will become too dry and the moist flavor of the castella cake will be lost.

ある。(d) Means for solving the problem In this invention, while the object to be fired is transported by the transport device, the object to be fired is fired using upper and lower heat sources disposed above and below the transport device. In the constructed tunnel kiln for baking confectionery and bread, a ceramic far-infrared radiation plate is disposed above the upper heat source so that it can be raised and lowered using a lifting mechanism.
The purpose is to provide a tunnel oven for baking bread.

ラの焼成をトンネル窯で行うことを可能とした。(E) Effect In this invention, the far infrared rays emitted from the ceramic far infrared radiation plate above the inside of the tunnel kiln heated by the upper heat source penetrates into the inside of the castella dough and directly heats the inside of the same dough. , the same dough is heated almost uniformly on both the surface and inside, eliminating the above-mentioned conventional drawbacks and eliminating the need for bubble removal and ash iron plate work.Therefore, high-quality castella cakes can be baked in a tunnel kiln. made it possible to do so.

The far infrared rays in this band excite the rotational vibrations of the fabric raw material molecules and generate heat in the fabric itself.The longer the wavelength, the less the attenuation in the middle, and the longer the distance it can reach inside the fabric. This wavelength can be adjusted by controlling the temperature of the radiation surface of the ceramic far-infrared radiation plate, and the same intensity can be adjusted by adjusting the distance between the radiation surface and the object to be fired.

The ceramic far-infrared radiating plate can be installed by adjusting the mounting height of the radiating plate so that the distance between the castella dough on the conveying device and the radiating plate is appropriate according to the baking process of the dough. Because it is possible
The castella dough is transported through a tunnel kiln using a transport device, and is then baked at a timely rate by irradiation with far-infrared rays and heating using conventional methods.
Since there is no need for intermediate work such as removing bubbles or making ash iron plates, it is now possible to fire castella cake using a tunnel kiln, which was previously considered impossible, and even inexperienced users can fire castella cake with high efficiency without making any mistakes. There is an effect that it can be done. Furthermore, since the above-mentioned effect is obtained when baking castella cakes, which requires the most advanced baking technology, it is clear that the above-mentioned effect can also be obtained when baking baked goods such as kutuki, cakes, etc., or breads. be.

る熔射工法を採用している。 In particular, a ceramic far-infrared radiating plate 11 is horizontally stretched above the upper heat source 8 at a predetermined interval, and the radiating plate 11 is attached to the lower surface of a metal substrate 12 made of aluminum alloy. A ceramic far-infrared radiation surface 13 is formed by coating far-infrared radiation material particles such as metal oxides such as boron, aluminum oxide, sodium oxide, and titanium oxide, and rare earth oxides using a blasting method using sodium silicate as a binder. The radiation surface 13 is heated by near infrared rays from a heat source and convection, and then far infrared rays are emitted from the radiation surface 13. Since a highly thermally conductive aluminum alloy is used for the metal substrate 12 of the ceramic far-infrared radiating plate 11, the temperature distribution of the radiating plate 11 is made uniform, and the wavelength and wavelength of the far-infrared rays emitted from the radiating plate 11 are therefore uniform. The strength is
Each part of the radiation surface 13 is uniform. In addition, methods such as enameling can also be used to coat the infrared radiation material.
The point is to attach the same material to the surface of the metal substrate in a state that can withstand high temperatures and allows good heat transfer from the substrate to the material. However, in order to promote scattering of the emitted far infrared rays and to equalize the intensity of far infrared rays in front of the emission surface, it is desirable that the radiation surface is rough.
From this point of view, this embodiment employs a hot-spraying method that produces a rough radiation surface.
