摘要:
An apparatus for extracting a vaporizable substance, from a material containing such substance, comprises an irradiation chamber for irradiating the material with electromagnetic radiation to vaporize the substance. The substance may comprise water and the material is dehydrated. The electromagnetic radiation comprises microwaves. The irradiation is conducted in the near-field range of the electromagnetic radiation. In one aspect, the electromagnetic radiation within the waveguide evanescently couples with the material.

Disclosed herein is a method for preserving a plant material. The method comprises applying a composition comprising a microwave attractant to the plant material; and then drying the plant material while exposing the plant material to microwave energy, wherein the microwave energy heats the plant material to a temperature effective to inactivate the majority of any browning enzymes in the plant material, and wherein the microwave attractant results in the heating of the plant material occurring at a rate whereby browning of the plant material by the browning enzymes during heating is substantially prevented. Also disclosed are uses of the preserved plant material.

A method for continuous processing food product is provided. The method includes providing a food product and a solution. The food product and solution are mixed so that the food product is equally distributed in the solution forming a food solution. The food solution is continuously pumped from a hopper or container through an electromagnetic or volumetric source, which rapidly heats the food solution. The processed food solution may then be filled in packages, such as flexible pouches.
摘要:
An apparatus and a method of drying and/or treating loose products such as food products, for example corn, flour, seeds in general, spices, tea and coffee, dried pulses, dried or shelled fruit, like hazelnuts, dry food products in general, such as dried mushrooms, etcetera, the treatment which the aforementioned loose products can be subjected to being of the type such as disinfestation, sanitization, pasteurisation, sterilisation, etcetera, wherein the aforementioned apparatus comprises a conveyor for the loose products, a treatment unit defining a treatment chamber, means for generating radio frequency electromagnetic radiation, means for applying radio frequency electromagnetic radiation and/or microwaves which act in the treatment chamber or area and designed to affect the loose products transported through the treatment chamber or area, mixing means for the loose products to be treated arranged in the treatment chamber.
摘要:
An apparatus and method for microwave vacuum-drying of organic materials, such as food products. The apparatus has a microwave vacuum chamber 20, a loading module 36 to load containers 38 of the organic material into the vacuum chamber, a rotatable cylindrical cage 64 in the vacuum chamber for rotating the containers, a piston 114 for moving the rotating containers through the vacuum chamber, and means for unloading the containers of dehydrated material from the vacuum chamber. The apparatus may include an equilibration chamber 150 for cooling the dehydrated material under reduced pressure, and a transfer module 42 to transfer the containers from the vacuum chamber to the equilibration chamber. The apparatus has a microwave transparent window 54 for transmission of radiation into the vacuum chamber, and a gas jet 58, 60, 62 for blowing a stream of gas, such as air or nitrogen, into the vacuum chamber adjacent to the window.
摘要:
Systems and methods for thermal preservation (sterilization) of heterogeneous and multiphase foods and biomaterials in order to achieve their shelf stability at ambient level temperatures. Flowing heterogeneous, multiphase foods and biomaterials are exposed to single or multiple stages of electromagnetic energy under continuous flow conditions within conduits passing through the electromagnetic energy exposure chambers.
