DRYING METHOD WITH FULLY CLOSED CYCLE OF DRYING AGENT Russian patent published in 2008 - IPC F26B3/04 

FIELD: drying processes of dispersed materials, possibly in microbiological, food making, chemical branches of industry.

SUBSTANCE: method comprises steps of condensing evaporated moisture due to feeding waste gas into cooler for cooling and drying by liquid vapor condensation; feeding dried gas into heater and then to drier; at first cooling gas at Xo = const till dew point; then condensing moisture vapor and performing further cooling of gas till temperature of initial mixture; determining cooling agent flow rate through surface type condenser with use of heat balance equation and determining total balance of mass and energy during process of cooling and vapor condensation according to calculation formula.

EFFECT: enhanced efficiency of drying process.
