FIELD: drying engineering.
SUBSTANCE: device has pad mounted on the bottom with a heater provided with differential pickups of heat flux connected with the differentiator. The device is additionally provided with polarized relay, first and second integrator, memory unit, divider, comparator, and set-point device which is interposed between the pickup of heat flux and differentiator. The first output of the recorder is connected with the input of the differentiator. The second output is connected with the first input of the polarized relay. The first output of the polarized relay is connected with the input of the first integrator. The second output of the polarized relay is connected with the input of the second integrator. The output of the first and second integrators are connected with the divider whose output is connected with the heater of the sublimation apparatus through the comparator connected to the generator and servomechanism.
EFFECT: enhanced efficiency.
