Experimental Studies Method 1. Drying same-type tissues samples in different conditions: • without ultrasound - temperature 120°С • without ultrasound - temperature 60°С • with ultrasound - without heating • with ultrasound - temperature 120°С • with ultrasound - temperature 60°С 2. Measuring the humidity over same time intervals. 3. Analysis of results. 40
