ABSTRACT

An apparatus for drying of capillary-porous matters (for example, biological objects and products of various branches of industry) without temperature increasing and destruction of products and matters structure is considered. Positive effect is obtained by means of ultrasonic vibrations of high intensity (150 dB). Ultrasonic does not heat a drying product and positively affects on consumer properties of product (for example, it save gustatory properties of products, increase a storage life and germinating capacity of seeds, etc.).
The disc radiator is developed and made for effective ultrasonic drying in contactless mode. The disk radiator generates ultrasonic field with intensity level not less 130 dB. For the first time the drying chamber of special form is used. This drying chamber ensures resonant amplification of intensity level up to 150 dB. All these technical decisions ensure efficiency of ultrasonic drying.
Results of experiments confirmed high efficiency of drying process by ultrasonic vibrations (increment up to 50 g per 1 kg of drying matter). That allows decreasing temperature of drying agent without losses of quality and speed of drying process. That attests availability and expediency of development of contactless drying units.

Key words: drying, ultrasonic, drying chamber
