Correct determination of the thawing time makes possible to design adequate installation and technology, it may also reduce the energy consumption. Thus, it is necessary to apply the proper formulas to predicting precisely that time for differentiated technological conditions and agricultural products. This paper characterized 12 analytical-empirical methods to predict the time of thawing, beginning from the oldest Plank's model up to most complex and developed model by Hossain et al. The way of formation, characteristics and application possibilities of graphical methods to predicting this value, were also described. It was started that there exist some limiting factors in all the methods resulting in inability of formulating whole mechanism of thawing process. Such a simulation keeps still developing of new, simplified method to calculate the thawing time for agricultural products and food.
