FIELD: heating, drying.SUBSTANCE: invention relates to thermal drying of the dough materials, in particular deposit of the treatment stations. Method contains two drying stages: first stage of drying (2) is of indirect type fed by hot fluid, it receives deposit with output dryness Se, and deposit is created at the output with intermediate dryness Si, and water steam that is directed to the condenser (8) for heating in it of the fluid loop for water heating, in particular, that in its turn will heat the heating gas for second stage of drying (6); stage (5) of deposit forming as cords at output of the first stage; second stage of drainage (6) of deposit cords by gas heated in particular partially by heat removed from the condenser. At second stage output the product is produced by final dryness Sf; at that intermediate dryness Si is adjusted depending on measured input dryness Se and required output dryness Sf for minimum total power consumption for drying; at that due to this flowrate, pressure and/or temperature of hot fluid (3) feeding the first stage of drying (2) are adjusted.EFFECT: reduced power and heat consumption.18 cl, 3 dwg |
