The Acoustic Drying Of Cloth In Drum-Type Washing Machines

Calorific Effect
• Absorption of ultrasonic oscillations
in wet material provides its heating
• Acoustic heating arising almost
uniformly on all deepness of
material, that promote water
transfer from deep layers.
• Calorific effect observes only under
high-intensity intensity ultrasonic (more 165
dB) and may be effectively using
for poured materials (e.g. sugar,
corn or silica).
• In the acoustic cloth drying calorific
effect show weakly and do not
influence to drying speed
