【考案の詳細な説明】
本考案は閃光放電灯を使用する殺菌装置に関す
るものである。[Detailed Description of the Invention] The present invention relates to a sterilization device using a flash discharge lamp.
従来、菌類の殺菌には、簡単な方法の１つとし
て殺菌灯による照射が利用されている。 Conventionally, irradiation with a germicidal lamp has been used as one of the simple methods for sterilizing fungi.
従来の殺菌灯は、消費電力が数十ワツト程度の
ものが普通で、特殊なもので200ワツト程度であ
る。たヾし、200ワツト程度になると殺菌灯の長
さが２米程の長大なものとなり、単位アーク長当
りの殺菌線の量は、特に著しく増大すると言うも
のではない。 Conventional germicidal lamps usually consume only a few tens of watts of power, with special types consuming around 200 watts. However, when the power is about 200 watts, the length of the germicidal lamp becomes about 2 meters long, and the amount of germicidal radiation per unit arc length does not increase significantly.
ところで、菌類にも非常に多種類あつて、例え
ば、黒カビのように光を良く吸収する菌の場合
は、表面の黒カビしか殺菌されず、重なつて、表
面の黒カビの下層に位置するものは非常に殺菌し
にくい。したがつて、従来の殺菌灯では、黒カビ
のように光をよく吸収する菌に対しては、殺菌時
間が長かつたり、殺菌率が低かつたりして、あま
り良い殺菌方法とは言えない欠点がある。 By the way, there are many types of fungi, and for example, in the case of fungi that absorb light well, such as black mold, only the black mold on the surface is sterilized; Very difficult to sterilize. Therefore, conventional germicidal lamps have drawbacks such as long sterilization times and low sterilization rates for bacteria that absorb light well, such as black mold, making them not a very good sterilization method. There is.
一般に、殺菌灯による紫外線殺菌効果は次の式
で与えられる。 In general, the germicidal effect of ultraviolet light from a germicidal lamp is given by the following formula:
Ｎ／Ｎ０＝ｅ−ｌ・ｔ／Ｑ
ｌ＝l0・ｅ-〓x
ｘ＝β・N0・Ｌ
こゝで、
N0：紫外線照射前の菌数
Ｎ：紫外線照射後の菌数
Ｑ：菌に固有の定数
ｌ：殺菌に有効な波長域の紫外線の強度
l0：菌の表面層へ照射される上記紫外線の強度
ｔ：照射時間
α：菌の上記紫外線吸収係数
β：定数
Ｌ：菌の層の表面からの深さ
である。したがつて、これらの式より、殺菌を有
効に行うためには、ｌ・ｔの値を大きくすれば良
いことが分る。α，βは菌の固有の定数であるの
で結局、ｌを大きくするか、もしくはｔを大きく
するかである。従来の殺菌灯では、l0したがつて
ｉも小さいのでｔを大きくせざるを得なかつた
が、それでも、黒カビの場合などでは表面層の殺
菌しかできず、殺菌率は低かつた。 N/N 0 = e-l・t/Q l=l 0・e - 〓 x x=β・N 0・L Where, N 0 : Number of bacteria before UV irradiation N: Number of bacteria after UV irradiation Q: Constant specific to bacteria l: Intensity of ultraviolet rays in the wavelength range effective for sterilization l 0 : Intensity of the above ultraviolet rays irradiated to the surface layer of bacteria t: Irradiation time α: The above ultraviolet absorption coefficient of bacteria β: Constant L : Depth from the surface of the bacterial layer. Therefore, from these equations, it can be seen that in order to effectively perform sterilization, the value of l·t should be increased. Since α and β are constants specific to bacteria, the final decision is whether to increase l or t. In conventional germicidal lamps, since l 0 and therefore i are small, t had to be made large, but even so, in the case of black mold, etc., only the surface layer could be sterilized, and the sterilization rate was low.
ところで、閃光放電灯は既に産業界で広く利用
されているが、この閃光放電灯は、発光成分とし
て稀ガスを含み、瞬間発光出力は従来の殺菌灯に
比べて104倍から107倍の強さを持つているので、
これを利用すれば前述の問題点を解決可能な殺菌
装置を得ることができる。 Incidentally, flash discharge lamps are already widely used in industry, but these flash discharge lamps contain a rare gas as a luminescent component, and their instantaneous luminous output is 10 4 to 10 7 times that of conventional germicidal lamps. Because it has strength,
By utilizing this, it is possible to obtain a sterilizer that can solve the above-mentioned problems.
ところが、被処理物が食品用の包装紙や容器の
蓋の場合は、高い殺菌率が要請されるとともに、

要がある。従つて閃光放電灯は閉空間内で発光さ

じる不具合があつた。 However, when the objects to be processed are food wrapping paper or container lids, a high sterilization rate is required, and
In the unlikely event that a lamp or the like breaks during sterilization, its fragments should not be allowed to adhere to the object to be processed. For this reason, instead of directly facing the object to be treated with a flash discharge lamp disposed in the box, it is necessary to interpose an ultraviolet-transmitting protection wall and irradiate the object through the protection wall. Therefore, since the flash discharge lamp emits light in a closed space, its temperature tends to rise, resulting in the problem of flash errors.

とする。 Therefore, the present invention provides a flash sterilizer that can safely sterilize flat objects to be treated using a flash discharge lamp at a high sterilization rate, and can operate the flash discharge lamp efficiently without causing flash mistakes. The structure consists of a box with an irradiation opening on one side, a cover glass placed in this opening, and a flash discharge lamp placed between the mirror inside the box and the cover glass. and a wind barrel connected to the box, so that cooling air is blown along the longitudinal direction of the discharge lamp.

いる。 Box 1 may have built-in flash discharge power equipment such as a trigger coil (not shown), but
A rectangular irradiation opening 1a is formed in the center of the lower surface, and a cover glass 2 made of quartz glass serving as an ultraviolet ray transmission protection wall is disposed in the opening 1a, so that the box 1 is a closed space. Above the cover glass 2, a flash discharge lamp 3, which is a U-shaped bulb made of quartz glass and has an inner diameter of 8 mm and an arc length of 270 mm, is supported horizontally by front and rear holders 4. . A mirror 5 is arranged behind the flash discharge lamp 3, and the flash light emitted from the flash discharge lamp 3 passes through the cover glass 2 and is irradiated downward from the opening 1a. The planar workpiece 6 is transported to the location and sterilized. Further, on both side walls of the box 1 in the longitudinal direction of the flash discharge lamp 3, a blowing wind cylinder 7 and an air exhaust wind cylinder 8 are provided. These wind barrels 7 and 8 are connected to a fan (not shown), so that cooling air is forcibly blown along the longitudinal direction of the flash discharge lamp 3.

い。 In the apparatus configured as described above, the object to be processed 6, which is food wrapping paper, is set at a predetermined position.
When the blower fan is activated, the flash discharge lamp 3 emits flash light. To give an example of flash sterilization, the irradiation intensity on the surface of the object 6 to be treated is approximately 2 Joule/cm 2 and the light emission cycle is once per second. When a flash is emitted, one flash can kill 99.999% of black mold, and three flashes can achieve an ultra-high sterilization rate of 99.99999%, which is higher than conventional ultraviolet germicidal lamps. This is a sterilization rate that can never be achieved. At this time, the cooling air that has been forcibly blown from the blowing wind cylinder 7 moves along the longitudinal direction of the flash discharge lamp 3 as shown by the arrow in FIG. be done. Therefore, the flash discharge lamp 3 is sufficiently cooled, but when the air flow rate is approximately 3 m 3 /min, the temperature of the bulb wall of the flash discharge lamp 3 is cooled to below 200 to 300°C, and at this temperature, the flash discharge lamp 3 cannot be emitted. The electric light 3 operates efficiently and does not cause flash errors.

することが可能である。 As explained above, in this invention, a flash discharge lamp is placed between the glass cover, which is an ultraviolet transmission protection wall, and the mirror, and the flash discharge lamp is emitted onto a flat object. In addition to being able to obtain a significantly higher sterilization rate than lights,
Even if a flash discharge lamp or the like is damaged, it is safe because no debris will adhere to the object to be treated. Since the cooling air is blown along the length of the flash discharge lamp, the flash discharge lamp is sufficiently cooled and operates efficiently without causing flash errors. Further, since the cooling air passes through the box in a closed space and does not come into contact with the object to be processed, there is no need to keep the cooling air in a sterile state. Therefore, according to the present invention, there is a flash sterilizer that can safely sterilize flat objects to be processed using a flash discharge lamp with a high sterilization rate, and that can operate the flash discharge lamp efficiently without flash mistakes. It is possible to provide
