摘要： A method of drying and pasteurizing food and pharmaceutical products in a vacuum microwave chamber (40), in which a relatively lower vacuum pressure step (14) is used for dehydration and a relatively higher vacuum pressure step (18) is used for pasteurization. The higher vacuum pressure is selected to provide a temperature in the vacuum microwave chamber that is effective for pasteurization. One or more pasteurization steps and drying steps can be used in the method. The invention permits both drying and pasteurization to be done in a single vacuum chamber in a continuous throughput process by controlling the vacuum pressure, and therefore product temperature, during each step.

摘要： An apparatus 20 for microwave vacuum-drying organic materials such as foods and bioactives has a plurality of microwave generators 50 actuated so as to cause interference between their respective microwave streams and evenly distribute the microwave energy across the vacuum chamber 34. The microwave-transparent window 36 in the chamber is arranged so the organic material to be dried is moved across it on a conveyor belt 60 and the microwave energy passing into the chamber 34 immediately encounters the organic materials, thus attenuating the energy and reducing arcing.

摘要： A method and apparatus for pasteurizing and drying marijuana plant materials using a microwave-vacuum chamber. The pasteurizing and drying are carried out with no use of ionizing radiation and with rapid drying. Pasteurization is done at a temperature and for a time period that are sufficient to reduce microorganisms to an acceptably low level, while not significantly reducing the psychoactive compounds in the material. In the process, the pressure inside a vacuum chamber is reduced to a first pressure less than atmospheric. The material is maintained in the vacuum chamber at the first pressure at a pasteurizing temperature while irradiating the material with microwave radiation. The pressure is then reduced to a second pressure lower than the first pressure and the material is maintained in the vacuum chamber at the second pressure for a time period at a dehydrating temperature lower than the pasteurizing temperature while irradiating the material with microwave radiation. The pasteurizing and dehydrating steps can be done in the reverse order.

摘要： A continuous-throughput vacuum chamber apparatus (20), in which the organic material to be treated in the vacuum chamber (34) is carried directly on the conveyor belt (54), has a cleaning station (86) for cleaning the conveyor belt as the belt moves. The cleaning station is external to the vacuum chamber, avoiding contamination of the vacuum chamber by removed material residues or cleaning preparations, and permitting a more thorough cleaning than if the cleaning station were inside the chamber. The invention reduces the need to shut down the vacuum chamber apparatus for cleaning and also makes it possible to monitor the status of contamination of the conveyor belt from the outside of the vacuum chamber. The apparatus (20) may be a vacuum microwave dehydrator.
