FIELD: sublimation drying.
SUBSTANCE: invention relates to devices for sublimation drying. Sublimation of thermolabile material is carried out using a device comprising a drying chamber and a condensation chamber, between which there is a multistage (two-stage) turbocompressor equipped with an intermediate steam cooler between the stages. Device is also equipped with a control unit, pressure and temperature sensors, valves and pumps. At the same time in the drying chamber conditions are provided below the water triple point, and the condensation chamber is provided with conditions above the water triple point.
EFFECT: increasing energy efficiency and accelerating the drying process.
