  • Patent number: 10760853
    Abstract: A system for condensing steam from an autoclave sterilizer includes a cooling tank and a condensing coil extending into the cooling tank. Cooling water from a source of water flows into the tank to cool the condensing coil when the temperature of the coolant in the cooling tank exceeds a predetermined value. A waste water drain is in fluid communication with the cooling tank. An air gap is located between the tank and the source of cooling water. The air gap includes an opening to atmospheric air and is configured to avoid back flow from a waste water drain toward the water source. A check valve may be used with or in lieu of an air gap to prevent back flow toward the water source.

  • Patent number: 9028750
    Abstract: Fumigation systems and processes that are especially applicable for the fumigation of perishable (or otherwise sensitive to temperature) agricultural products as the temperature conditions under which the product is being treated are closely controlled to advantageously prevent the product from being exposed to temperature drops and/or spikes during the fumigation cycle. In addition, the present invention incorporates an air filtration system as a part of the fumigation system to substantially remove the toxic fumigant residuals from the air before it is exhausted into the open atmosphere, which typically occurs at the completion of a fumigation cycle. As such, the harmful effect of the fumigant on the products and the surrounding environment and work areas is greatly minimized. In summary, the systems and processes of the present invention provide the ability to conduct fumigations in a well-controlled environment.

  • Publication number: 20130302211
    Abstract: A method and device related to a liquid product pressure and (optionally) temperature treatment method reduces the level of microorganisms in the liquid product to a preselected level. Utilizing the method, liquid product is diffused in a chamber with the speed of pressure variation of liquid product in one embodiment of about 109 Pa/sec. The preferred speed of the diffused drops is about 10 m/sec. The liquid product can optionally be heated before or during diffusion, and is preferably heated as a diffused liquid product by mixing it with superheated steam.

  • Publication number: 20130243662
    Abstract: A pressure vessel and a drum rotatably arranged inside which has an inner space for material that is introduced into the pressure vessel. In various embodiments, a drive mechanism rotates the drum in relation to the pressure vessel. The drive mechanism can include a motor that can be located inside the pressure vessel in an interspace between the drum and the pressure vessel. Some embodiments include a door to close an opening of the pressure vessel and a part of the door can extend into an open end of the drum when the door is closed to keep the material in the drum and out of the interspace. In particular embodiments, a steam supply conduit extends into the drum at the closed end of the pressure vessel. In some embodiments, a helical agitation blade in the drum moves the material away from or toward the opening.

  • Patent number: 8517709
    Abstract: Disclosed herein are methods and pressure vessels for solid-state microcellular processing of thermoplastic rolls and sheets. In one embodiment, the present invention is directed to a method for making a gas impregnated interleaved roll, which method comprises: providing a pressure vessel having an internal pressure chamber and a rotatable shaft horizontally positioned within the pressure chamber; placing an interleaved roll about the rotatable shaft and within the pressure chamber, wherein the interleaved roll is made from a thermoplastic material sheet interleaved together with a gas-channeling material sheet; pressurizing the pressure chamber to a selected pressure; rotating the rotatable shaft having the interleaved roll thereabouts (thereby rotating the interleaved roll) while under pressure for a selected period of time; and depressurizing the internal chamber to yield the gas impregnated interleaved roll.

  • Publication number: 20130142694
    Abstract: The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water. The method comprises the following steps: generating a plasma from air as the process gas, which forms reactive nitrogen and oxygen species; oxidizing NO to form NO2 at temperatures below 400° C. so that a plasma-activated gas mixture forms having an NO2 content of at least 0.3%; bringing said plasma-activated gas mixture in contact with water in one or more of the states of aggregation thereof; bringing the latter gas mixture in contact with the objects to be decontaminated or sterilized.

  • Patent number: 8453671
    Abstract: An apparatus for controlling an internal pressure of a hermetically sealed chamber at a prescribed pressure level serves to relax pressure changes in the hermetically sealed chamber. The chamber is connected to an inlet passage for supplying air from an external environment through an aseptic filter, an outlet passage for discharging a gas through an aseptic filter, and an inlet valve and an outlet valve for selectively opening and closing the inlet passage and the outlet passage, respectively. The apparatus also includes a controller for controlling the inlet valve and the outlet valve to keep the internal pressure of the chamber at a prescribed positive pressure level. An elastic membrane of silicone rubber which is expanded or retracted depending on a change in the internal pressure of the chamber to relax the pressure change is connected to the outlet passage between the aseptic filter and the outlet valve.
