【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、簡便な方法の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, and the ones that overlap and are located below the black mold on the surface are 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。 Generally, the ultraviolet sterilizing effect of 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
ｌ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, l0 and therefore l are small, so t has to be increased, but even so, in cases of black mold, etc., only the surface layer can be sterilized, and the sterilization rate is 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。そして容器状の被処理
を殺菌する場合は、Ｕ字状の閃光放電灯を容器内
に挿入した状態で発光させると有効に殺菌するこ
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. When a container-shaped object to be treated is to be sterilized, it can be effectively sterilized by emitting light from a U-shaped flash discharge lamp inserted into the container.
ところが、被処理物が食品用の容器の場合は、
高い殺菌率が要請されるとともに、殺菌中に万一
にもランプなどが破損してその破片が被処理物に
付着することは許されないので、Ｕ字状の閃光放

を通して照射する必要がある。従つて閃光放電灯
は閉空間内で発光されるのでその温度が上昇しや
すく、このために作動効率が低下し、閃光ミスが
生ずる不具合があつた。 However, if the object to be processed is a food container,
A high sterilization rate is required, and it is unacceptable for the lamp to break during sterilization and its fragments to adhere to the treated object, so a U-shaped flash discharge lamp is housed inside an ultraviolet-transparent protection tube. It is necessary to place it and irradiate it through this protection tube. Therefore, since the flash discharge lamp emits light in a closed space, its temperature tends to rise, which causes problems such as a decrease in operating efficiency and the occurrence of flash errors.

However, to give an example of flash sterilization, if the irradiation intensity on the inner surface of the object to be treated 5 is approximately 2 Joule /cm 2 and the flash is emitted at a light cycle of once per second, one flash sterilization The light emission can kill 99.999% of black mold, and three flashes can achieve an ultra-high sterilization rate of 99.99999%, which is a sterilization rate that can never be achieved with conventional ultraviolet germicidal lamps. At this time, the cooling air forcibly blown from the wind barrel 9 is forced into the glass cup 4 through one of the two openings 1b as shown by the arrows in FIG. When it reaches the vicinity of the lower end, it changes direction and rises again along the opposite valve wall, enters the box 1 through the other half of the opening 1b, and is discharged to the outside by the exhaust duct 8. is discharged. Therefore, although the flash discharge lamp 3 is sufficiently cooled, the amount of air blown is approximately 3 m 3 /
minutes, the bulb wall temperature of flash discharge lamp 3 is 200
It is cooled to below ~300°C, and no flash misses occur at this temperature. If a partition wall is provided between the U-shaped bulb walls of the flash discharge lamp 3, the entire amount of the cooling air forced into the glass cup 4 will surely reach the lower end, thereby further enhancing the cooling effect.
