| Summary: | The aim of this work is to construct heat transfer model which can describe well the
heat transfer process, as well as can be used to predict the greenhouse air temperature,
product temperature and moisture evaporation during drying. Drying is conducted in the
room dryer for 9 samples where each sample is ± 150 grams and is divided into 3 sample
placed on the bottom shelf, 3 samples on middle shelf, and 3 samples on the top shelf. Drying
is carried out from the initial moisture content of material ± 63-64% to 12-14% for the
standard fries. Mathematic model was simulated in MATLAB software, and was validated by
comparing the analytical and experimental result. The heat transfer model could describe well
the heat transfer process during drying. It was shown that theanalytical and experimental
result are in good agreement, with mean error range values 5,38-20,4 %.
