A continuous differential-pressure steam sterilization system for a powder, and belongs to the field of material sterilization includes: a superheated steam generation system, a steam pressure and flow rate control system, a quantitative feeding system, an instantaneous differential-pressure sterilization system, a dust explosion suppression system, a sterile cooling system, a primary gas-solid separation system, a secondary gas-solid separation system, a sterile storage system, a steam recovery and reheating system, and a condensate recovery system. The continuous differential-pressure steam sterilization system shortens the thermal contact time and mainly accumulates the heat on the surface of the powder, rather than in the center of the powder, which reduces the damage to the nutritional quality of the powder. Comprehensive treatment methods such as superheated steam, temperature compensation and non-sticky inner lining are adopted to reduce the problem of powder binding, agglomeration, and even blocking in the pipe of the system.

Surface disinfection for enclosures with Ultra-Violet (UV) light and illuminating such enclosures with visible light. Particular embodiments relate to limiting the transmission of viruses and bacteria in the interior space of an aircraft, such as a lavatory, through the use of UV light application, while providing visible light to passengers of such lavatory, both in a safe and compliant manner. This disclosure provides a lighting system and method that combines a visible light emitter and a UV light emitter into a single light system module. Although UV light is a preferred method of neutralizing pathogens, its use is not safe for human exposure. Accordingly, the disclosed lighting system is capable of detecting the presence of an occupant within an enclosure or defined space and only allows the visible light emitter to function (and prevents the UV light emitter from functioning) while people or animals are present within the electromagnetic range for the lighting system. The lighting system can then detect the absence of an occupant within an enclosure or defined space, prior to activating the UV light emitter, and once absence is detected, the UV light emitter can be activated by a controller.

A vessel sterilizer includes a gripper which is configured to hold a vessel having an opening facing upward, the endless conveyor being configured to move the gripper in a conveyance direction along a conveyance rout; a nozzle provided on the conveyance rout and configured to inject sterilizing gas from a spout provided at a bottom end of the nozzle toward the opening of the vessel to supply the sterilizing gas into the vessel; and a swing mechanism configured to horizontally swing the gripper forward in the conveyance direction when the vessel held by the gripper approaches the nozzle along the conveyance rout and configured to horizontally swing the gripper rearward in the conveyance direction when the vessel held by the gripper moves away from the nozzle.

A secure box for receiving packages is described. The secure box includes a rectangular container with a top, a bottom, a front, a left, a right, and a back. A front door forms part of the front when in a closed position, the front door having at least one hinge allowing it to move to an open position by swinging outward at a top end. A top cap with one or more photovoltaic panels formed therein, the top cap adapted to securely fasten onto the top. A package sensor senses a package placed in the rectangular container to initiate a decontamination process. A controller is electrically coupled to one or more photovoltaic panels, and the controller is communicatively coupled to the package sensor to control a decontamination system for decontaminating the package which has been sensed. The decontamination system includes at least one of ultraviolet light source, a chemical spray, or both.
