    • A method and apparatus for cleaning a stack of secure instruments such as banknotes is disclosed. Each secure instrument or banknote includes a substrate, visual data and a security feature. The apparatus includes a chamber configured to contain a supercritical fluid at a temperature and a pressure and for a duration sufficient to disinfect or decontaminate the banknotes and not compromise the security feature and the visual data of the banknotes, a structure for holding the stack of banknotes in the chamber so that the supercritical fluid circulates through and around the banknotes to remove one or more substances into the supercritical fluid, and a strapping machine configured to secure a securing mechanism to the stack of banknotes.

    • Objects with complex surface profiles can be cleaned effectively using hyperbaric pressure. After partially submerging an object in a superheated liquid, the pressure of the vapor portion of the superheated liquid can be cycled. For example, a valve connected to the vapor portion of the superheated liquid can be opened to an ambient, such as atmospheric ambient to release the chamber pressure. The chamber pressure then can increased, for example, by re-equilibrium or by introducing superheated vapor or heated vapor or gas. During the release of pressure, bubbles can formed on the surface of the object. During the increase of the pressure, the bubbles can be collapsed. The cycling of the bubbles can clean the object surface. Objects can be dried by a quick release of superheated vapor. After providing a superheated vapor to a chamber, the superheated vapor can be released. During the release of pressure, liquid droplets can be evaporated, drying the object.
    • 具有复杂表面轮廓的物体可以使用高压来有效清洁。 在将物体部分地浸没在过热液体中之后,过热液体的蒸汽部分的压力可以循环。 例如,连接到过热液体的蒸汽部分的阀可以打开到诸如大气环境的环境以释放室压力。 然后,腔室压力可以例如通过再平衡或通过引入过热蒸汽或加热的蒸气或气体而增加。 在压力释放期间,在物体的表面上可形成气泡。 在压力增加期间,气泡可能会倒塌。 气泡的循环可以清洁物体表面。 物体可以通过快速释放过热蒸气来干燥。 在向室提供过热蒸汽之后,可以释放过热蒸汽。 在释放压力期间,液滴可以蒸发,干燥物体。
