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： A process for making a shelf-stable food, not requiring preservatives or refrigeration and in a form that is convenient for use as a snack food. A block of tofu or wheat gluten is first frozen so as to cause the formation of ice crystals that form cavities within the block. The frozen block is then thawed, cut into smaller pieces and drained of excess water. The thawed pieces are dried in a microwave-vacuum dehydrator to produce a crunchy food product.

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 for producing foams, such as sponges, from hydrocolloids is described. A solid or semi-solid gel is formed by dissolving polymeric material in an aqueous solvent. The gel formed is allowed to set, and may optionally then be cut into the desired shape. The gel may be frozen to allow formation of ice crystals to act as porogens. Subsequently, the gel is exposed to a radiant energy field for drying under vacuum. This causes the solvent to boil and the foam or sponge is formed. Medicinally active ingredients may be included in the process, so that the sponge or foam formed contains the active ingredient dispersed within the structure. The method described provides an alternative to the conventional methods of particulate leaching or freeze drying.

摘要： A method of making a porous, dehydrated food product comprises subjecting a food product to pulsed electric field treatment to form pores in the cell membranes of the food product, freezing the treated food product, and exposing the treated frozen food product to microwave radiation in a vacuum chamber at a pressure that is less than atmospheric and at which the boiling point of water is above 0° C., causing the frozen food product to thaw and water to evaporate to produce the porous, dehydrated product. The process is faster than freeze-drying and consumes less energy. The pulsed electric field treatment does not result in structural damage to the product, despite the thawing of the frozen product during the drying process.

摘要： A method for producing foams containing biological materials is described. A solid or semi-solid paste is formed by combining biologically active material with a protecting agent in an aqueous solvent. The paste formed is allowed to set, and may optionally then be apportioned into the desired shape. The paste may be frozen to allow formation of ice crystals to act as porogens. Subsequently, the paste is exposed to travelling wave radiant energy under vacuum (t-REV) for drying. This causes the solvent to boil off, leaving dried material containing the biologically active material, the protecting agent, and a relatively low water content. Biologically active materials which can be used include cells, microbial cultures, live attenuated microbes, probiotics, yeasts, enzymes, vaccines, proteins, and any heat-sensitive biological material. By directing energy via a travelling wave through a sample, good control of temperature and process conditions can be achieved. The method provides an alternative to the conventional methods of particulate leaching or freeze drying.

摘要： Methods for drying cannabis in continuous throughput-type and batch-type microwave vacuum drying apparatus. One method uses a vacuum chamber having a plurality of adjacent drying zones. The cannabis is conveyed through each of the zones while exposing it to microwave radiation. Each of the drying zones has a microwave power level different from that of an adjacent drying zone, the microwave power levels of zones varying from each other in a non-linear arrangement from the first zone to the last zone. In a batch method, cannabis is loaded into a vacuum chamber, the pressure is reduced, and the cannabis is irradiated with microwave radiation at a first power level. The surface temperature of the cannabis is measured and when the temperature exceeds a specified temperature for a time period greater than a first time period, the power level is reduced to a lower power level for a second time period. The methods of drying maximize the retention of terpenes in the cannabis.
