摘要： A method and apparatus for pasteurizing and drying cannabis 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： 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： An apparatus and method for microwave vacuum-drying of organic materials such as food products. The dehydration apparatus (20) has a vacuum chamber (24) with an input module (28) at one end and a discharge module (32) at the other. The vacuum chamber has access doors (80) spaced between the input end (30) and the discharge end (34) which provide operator and maintenance access. Microwave generators (86) are mounted on each access door and arranged to radiate through a microwave chamber and microwave-transparent window on the access door into the vacuum chamber. A pair of rollers (60) in the vacuum chamber rotates the container of organic material (112) about a horizontal axis, and a chain drive (64) pulls the containers along the rollers through the vacuum chamber.

摘要： An apparatus and method for microwave vacuum-drying of temperature-sensitive biological materials on a continuous flow-through basis, in which the materials are frozen, ground to frozen particles, dehydrated to a powder, and the powder collected. The apparatus has a microwave generator and waveguide, a freezing chamber with a grinder, a rotatable dehydration chamber in or adjacent to the waveguide, and a powder collector to receive the powdered biological material. The apparatus operates under reduced pressure provided by a vacuum system coupled to the powder collector.

摘要： An apparatus (20) for dehydrating organic material in batches has a processing unit (22) having a microwave-vacuum chamber (34), an input module (28) and an output module (30), with a conveyor (54) for moving the material through the chamber on a microwave-transparent window. A material reservoir (68) is arranged to receive the material exiting the output module. A conveyor (78) external to the vacuum chamber conveys material that exits the reservoir to the input module. The vacuum chamber (34), reservoir (68) and external conveyor (78) are in fluid communication to operate at a common, reduced pressure. The organic material passes through the vacuum chamber multiple times to equilibrate and dry to the desired degree.

摘要： An apparatus and method for microwave vacuum-drying of organic materials such as food products. The dehydration apparatus (10) has a vacuum chamber (12) with a loading module (14) at one end and a discharge module (22) at the other. The vacuum chamber has access doors (80) spaced between the input end (16) and the discharge end (24) which provide operator and maintenance access. Microwave generators (86) are mounted on each access door and arranged to radiate through a microwave chamber and microwave-transparent window on the access door into the vacuum chamber. The waveguides on a respective access door are oriented to minimize microwave interference between the magnetrons on that door. A conveyor (60) in the vacuum chamber moves the organic material (96) on trays (18) through the vacuum chamber.

摘要： An apparatus and method for dehydrating biological materials, such as vaccines and microorganism cultures, in which the materials are dehydrated in an evacuated container which is in a microwave waveguide that is open to the atmosphere. The apparatus comprises means for freezing the container of biological material, a microwave generator, a waveguide, means for introducing the container into the waveguide, means for applying a vacuum to the container and means for removing the dehydrated material from the waveguide. In the method of the invention, the container of biological material is put in a microwave waveguide open to the atmosphere, a vacuum is applied to the container, the material is frozen and is radiated to dehydrate it. The dehydrated material is then removed from the waveguide.
