摘要： Methods and apparatuses are described for food product preservation by deactivation of microorganisms and enzymes by applying high-intensity, short-duration pulses of polychromatic light in a broad spectrum to packaging material surfaces. In some embodiments, a photodiode is employed for detecting the intensity of the light, and a control circuit is used to adjust power delivered to a flashlamp if the intensity of the light needs adjustment. In some embodiments, an outer safety glass is employed to protect the flashlamps. The outer safety glass may include coating materials at ends thereof. In addition, several variations of lamp assembly geometries accommodate small diameter packaging material tubes by, for example, using a fill pipe having offset first and second portions with a transitional region thereinbetween, or be eliminating the water jackets and using an outer safety glass to contain water as it is passed over flashlamps. In another additional embodiment, a lamp holding device includes a holding cylinder with a first flange, which, together with a compression cylinder, compresses the first O-ring into the flashlamp. In yet another embodiment, a lamp holding device is positioned in a receptacle into which an electrode of a U-lamp is inserted. The lamp holding device allows a proximal portion to move relative to a distal portion thereof. In yet a further embodiment, a light guide is positioned to receive light emitted from a linear flashlamp and to transmit such light into a packaging material cup.
摘要翻译：通过将广泛的高色度，短时间脉冲的多色光脉冲施加到包装材料表面，描述了通过使微生物和酶失活来保护食品的方法和装置。在一些实施例中，使用光电二极管来检测光的强度，并且如果光的强度需要调整，则使用控制电路来调节输送到闪光灯的功率。在一些实施例中，采用外部安全玻璃来保护闪光灯。外部安全玻璃的末端可以包括涂层材料。此外，灯组件几何形状的几种变型通过例如使用具有偏移的第一和第二部分的填充管，其间具有过渡区域，或者消除水套和使用外部安全玻璃来容纳小直径的包装材料管水通过闪光灯。在另一个另外的实施例中，灯保持装置包括具有第一凸缘的保持筒，压缩圆筒与第一凸缘一起将第一O形环压入闪光灯。在另一个实施例中，灯保持装置定位在插入U形灯电极的插座中。灯保持装置允许近端部分相对于其远端部分移动。在又一个实施例中，光导被定位成接收从线性闪光灯发射的光并将这种光透射到包装材料杯中。

摘要： An approach for sterilizing microorganisms at a target object employs a flashlamp system including means for generating pulses of light, and for deactivating microorganisms within the target object by illuminating the target object with the pulses of light having been generated; a photo-sensitive detector positioned so as to receive a portion of each of the pulses of light as a measure of an amount of light illuminating the target object, for generating an output signal in response thereto; and a control system, coupled to the flashlamp system and the photo-sensitive detector, for determining, in response to the output signal, whether the pulses of light are sufficient to effect a prescribed level of deactivation of microorganisms in the target object. In accordance with this approach sterilizing microorganisms involves steps of generating a pulse of light; deactivating microorganisms at the target object by directing the pulse of light having been generated at the target object; receiving a portion of the pulse of light as a measure of an amount of the pulse of light illuminating the target object; generating an output signal in response to the receiving of the portion of the pulse of light; and determining, in response to the generating of the output signal, whether the pulse of light is sufficient to effect a prescribed level of deactivation of microorganisms in the target object.
