  • Patent number: 6226889
    Abstract: The present invention relates to a method and apparatus for use in removing at least one volatile contaminant from contaminated material by using a rotary vacuum retort during high temperature and vacuum processing. The loading and unloading are performed in a manner that minimizes the introduction of low boiling point gases. The apparatus employs, in one preferred embodiment, elastomeric pinch valve airlocks to isolate the entire system between the airlocks and a vacuum generator. The apparatus employs, in another preferred embodiment, at least one material transfer element. Furthermore, the contaminated material may be dried in a dryer prior to introduction into the retort. Moreover, the decontaminated material can be cooled through a heat exchanger prior to discharge.

  • Patent number: 6143136
    Abstract: A method and apparatus for separating volatile from nonvolatile substances, separation of volatile substances, one from the other, and for performing various chemical reactions. In particular, an apparatus which performs these functions utilizing a combination of above ambient temperatures and above one inch of mercury vacuum within a rotating vessel. The apparatus uses a conventional rotary vacuum seal. The apparatus, however, operates well above the maximum operating temperature of the conventional rotary vacuum seal by isolating and cooling the conventional rotary vacuum seal.

  • Patent number: 6105275
    Abstract: The present invention relates to a method and apparatus for use in continuously loading material to be treated into a rotary vacuum retort and continuously unloading one or more vapors or similar volatile substances and treated material out of the rotary vacuum retort during high temperature and high vacuum processing. The loading and unloading are performed in a manner that minimizes the introduction of low boiling point gases. The apparatus employs, in one preferred embodiment, elastomeric pinch valve airlocks to isolate the entire system between the airlocks and a vacuum generator. Furthermore, the material being treated may be dried in a dryer prior to introduction into the retort. Moreover, the processed material can be cooled through a heat exchanger to permit the use of a low temperature pinch valve airlock on the discharge end of the process.

  • Patent number: 5628969
    Abstract: The present invention is an apparatus for use in the separation of volatile from non-volatile substances, separation of volatile substances, one from the other, and for performing various chemical reactions and, in particular, to an apparatus which performs these functions utilizing a combination of above ambient temperatures and above one inch of mercury vacuum within a rotating vessel fitted with or without an internal filter through which exiting gases and vapors must pass. Because of the compactness allowed by the present invention, the apparatus can also be configured to operate in a self contained mobile mode.
