  • Patent number: 9259029
    Abstract: A system providing for on-site reclamation and re-use of reclaimed antimicrobial solution includes a dispenser, at least one receptacle, piping, and at least one pump. The dispenser sprays antimicrobial solution toward moving raw food products. Unspent antimicrobial solution that did not contact the moving raw food products and rebound antimicrobial solution that did contact the raw food products combine to form a reclaimed antimicrobial solution. The reclaimed antimicrobial solution is collected in the receptacle and is pumped through the piping to a location for reuse.

  • Patent number: 9101679
    Abstract: A method of sterilizing an article by sequentially exposing the article to hydrogen peroxide and ozone is disclosed. The article is exposed under vacuum first to an evaporated aqueous solution of hydrogen peroxide and subsequently to an ozone containing gas. The exposure is carried out without reducing the water vapor content of the sterilization atmosphere, the water vapor content being derived from the aqueous solvent of the hydrogen peroxide solution and from the decomposition of the hydrogen peroxide into water and oxygen. The complete sterilization process is carried out while the chamber remains sealed and without removal of any component of the sterilization atmosphere. For this purpose, the chamber is initially evacuated to a first vacuum pressure sufficient to cause evaporation of the aqueous hydrogen peroxide at the temperature of the chamber atmosphere. The chamber is then sealed for the remainder of the sterilization process and during all sterilant injection cycles.

  • Publication number: 20150139854
    Abstract: To improve throughput of biomedical waste treatment, the present inventors devised an exemplary ozone-based system including a shredder, a roll-off treatment bin with ozone injectors, an ozone source, and a controller. The controller monitors electric current drawn by the shredder as shredded waste enters the ozone-enriched treatment bin. In response to current falling below a predetermined low level, indicating that a batch of waste has been shredded and loaded into the treatment bin, the controller starts a treatment timer. The timer measures elapsed ozone treatment or exposure time. If additional waste is added to the shredder and a subsequent low-current condition is detected, the controller restarts the treatment timer. Expiration of the timer indicates that the waste in the roll-off bin is sterilized and ready for transport to landfills. The exemplary system provides continuous waste processing and promises to boost throughput by 50% over some conventional ozone-based waste-treatment systems.

  • Publication number: 20150044094
    Abstract: The present disclosure pertains to a ventilator treatment system configured to sterilize and/or disinfect a fluid pathway through a ventilator by providing a forced flow of treatment gas to the ventilator. Ventilators are frequently contaminated with bacteria and viruses during normal use. When a ventilator is moved from one patient to the next, there is a risk of contaminating the new patient with a pathogen from the previous patient. The application of treatment gas is especially practical for sanitizing hard to access surfaces such as those found in the cavities and conduits (the fluid pathway) of a ventilator. A treatment gas such as, for example, ozone, converts back to oxygen and has a short half life, which can be further reduced with humidity, heat, or inexpensive destruct catalysts.

  • Publication number: 20150010432
    Abstract: An apparatus and method for achieving low temperature vapor sterilization of objects which may involve objects having a lumen. Following evacuation of the sterilization chamber and the introduction of a vaporous or gaseous sterilant, the volume of the chamber is changed by actuation of a movable boundary in the chamber to increase and decrease the pressure in the chamber thus driving the sterilant into and out of such lumens.

  • Patent number: 8916093
    Abstract: The disclosure relates to an apparatus (10) for decontaminating an enclosure that includes a passage having an inlet (18) to receive a carrier gas from the enclosure, an outlet (31) to discharge the carrier gas to the enclosure, a fan (21) for causing a low of carrier gas through the passage from the inlet to the outlet, and a vapour generator (19) where a decontaminant vapour is introduced into the flow of carrier gas to be discharged with the flow at the outlet to decontaminate the enclosed space. A further fan (33) delivers a separate flow of gas from the enclosure bypassing the passageway in which the decontaminant vapour is introduced to be delivered into the enclosure from outlet vents (32) adjacent the vapour outlets (31) to assist in dispersing the carrier gas containing decontaminant vapour throughout the enclosure.

  • Publication number: 20140356231
    Abstract: Systems and processes to dispense, clean and sanitize the key exposure points in the filling process to reduce risk of mold, yeast, or bacteria product spoilage, with minimal downtime. In some embodiments, a process uses a chemical solution that includes a liquid including potable water or another liquid—such as paramagnetic water, ultrapure water, R.O. water or any other kind of modified water—and a biocide solution such as sodium hypochlorite, stabilized chlorine dioxide, etc. at concentrations between 0.5 and 200 ppm or any of the components of electrochemical activated (EAC) water. In some embodiments, the water has a low enough chemical concentration to allow application without a follow-up rinse. The high ORP water at high pressure and flow removes the statically charged particles, preventing micro growth in between sprays, and effectively cleaning and sanitizing in a single step.
