Abstract

In this paper an original solution of a small capacity infrared dryer for home use for drying biological material is given. The dryer is transportable, with small dimensions and is characterized by a cylindrically shaped drying chamber. An infrared heater is placed in the center of the dryer. Five vertical cylinders with perforated walls for placing material in the drying process are positioned around the heater. Due to the construction of the mechanical transporter in the drying process the cylinders rotate around their vertical axis, thus leading to more uniform heating of the material volume and a stage radiation regime. The dryer dimensions are: maximal width 320 mm and height 450 mm. The dryer capacity of moist material is around 2, 5 kg. In the paper has defined the mathematical models for analysis of the influence of the material types, shape and dimensions of the surface undergoing on the drying process. Based on analytical equation, defined of the mathematical models, and drying kinetics were defined based on experimental results drying process of apples in infrared and convective dryer small capacity, gives the graphical dependence and corresponding analysis.
