FIELD: solar engineering; technological processes.;SUBSTANCE: invention relates to solar engineering and is intended for drying of various products around-the-clock. Constant maintenance of dry air supply to drying chamber is provided by two alternating adsorbers. Stable maintenance of heated air temperature, which is optimum for drying of selected material, and supplied to drying chamber is provided by the first solar collector. And the second solar collector ensures uninterrupted supply of heated air to the adsorber operating in regeneration mode and heated to optimum for drying of moistened adsorbent. Each solar collector comprises a phase-transfer heat accumulator, melting point of heat-accumulating composition of which is equal to optimal temperature of corresponding process of its intended use.;EFFECT: technical result consists in continuous supply of dried and heated to preset temperature air into drying chamber and performance of round-the-clock and uninterrupted drying process.;1 cl, 1 dwg
