摘要:
A method of drying an organic material by microwave-vacuum drying below butclose to the triple point of water has beendetermined to allow more conversion of microwaves to heat than would occurwhen microwave freeze-drying at lower pressures. Themethod comprises introducing the organic material into a microwave-vacuumdehydrator, exposing the organic material to microwaveradiation in the dehydrator to dry the organic material by sublimation, andmaintaining pressure in the dehydrator in the range of 0.5Torr to 4.5 Torr. The method provides the benefits of reduced drying time,energy requirements and product temperatures, relative todehydration done at lower vacuum pressures.
