"The aim of this work was to study the infrared (IR) drying of food products. In present article are investigated the effects of blanching, of air velocity and of different air temperatures on the drying time and on the rehydration ratio as a quality property. During research different food materials were used: apple, carrot and potato. In the article is presented a simultaneous heat and mass transfer model that calculates the rate of moisture vaporization with the approximation less than 10 % for 20-30 min of the 1st period of the drying process. The food materials slices were dried by near infrared (NIR) heating by the natural, and by the forced convections with air velocities 0.25 and 0.5 m/s and at different air temperatures 22.8 and 28 \u00B0C." . . . . .
