    摘要: Device and method suitable for disinfecting herbs using plasma are disclosed. The device comprises a chamber and two sets of electrodes in an opposed position one relative to the other, inside the chamber. Each electrode in one set has a counterpart electrode in the other set, the two electrodes positioned facing each other and being configured to connect to a RF HV power supply, to produce a plasma-generating EM field in the space between the electrodes. The device further comprises a dielectric carrier positioned inside the chamber in the space between the two sets of electrodes, the carrier being dimensioned and configured to carry herbs in granular form such as powder or particles thereon. A portable sealable container comprising a unidirectional valve is also disclosed, configured to store herbs thereinside during plasma treatment in the device, and to store the disinfected herbs after treatment under vacuum. A device for disinfecting herbs by evaporating a disinfection agent in an evacuated chamber is also disclosed where plasma is used in any of several methods to enhance, improve and expedite the disinfection process.

    摘要: An automated robotic food handling or preparation apparatus includes one or more food contact surfaces and an antimicrobial lighting fixture. The antimicrobial lighting fixture includes an enclosure forming a sanitization chamber and one or more antimicrobial lighting elements, wherein each element emits light at a wavelength, irradiance, and direction sufficient to inactivate one or more microorganisms on a target surface(s) within the sanitization chamber. The automated food handling apparatus subjects itself to an antimicrobial lighting treatment within the sanitization chamber upon detection of one or more conditions. The systems and/or methods of the present disclosure may sanitize food contact surfaces of automated robotic food equipment and help reduce the frequency at which such food contact surfaces need to be manually sanitized to keep microbial growth below acceptable levels.

    摘要: A chamber can be a pathogen control device, which can include a body having at least one internal wall defining an internal chamber, and a layer of a two dimensional material on at least a portion of the at least one internal wall. The two-dimensional material can have at least one edge protruding from the at least one internal wall. A pathogen control system can include the chamber and at least one pressure source operably coupled with an inlet of the internal chamber, and optionally include a depressurization vessel. A method of processing a fluid, such as for controlling pathogens, can include providing the chamber, and flowing a fluid with or without pressurized carbon dioxide or processing fluid through the internal chamber of the chamber to contact an edge of the two-dimensional material. The flow through the chamber can be conducted until at least one pathogen is controlled.
