Claims (1)

Способ сушки плодоовощного сырья, включающий пропитку сырья жидкой двуокисью углерода при давлении выше атмосферного, сброс давления для вспенивания или вспучивания сырья и удаление влаги при повышении температуры и снижении давления, отличающийся тем, что сброс давления осуществляют в два этапа, на первом из которых скорость снижения давления задают на уровне, исключающем замерзание влаги, а на втором - на уровне, обеспечивающем замерзание влаги, при этом удаление влаги осуществляют методом сублимации под вакуумом.A method of drying fruit and vegetable raw materials, including impregnating the raw material with liquid carbon dioxide at a pressure higher than atmospheric pressure, relieving pressure to expand or expand the raw material, and removing moisture when the temperature rises and pressure drops, characterized in that the pressure is released in two stages, the first of which is the rate of decrease pressure set at a level that excludes freezing of moisture, and at the second - at a level that provides freezing of moisture, while the moisture is removed by sublimation under vacuum.
