The work is dedicated to the calculation of energy costs for the realization of the process of convective drying of fruits and berries in a suspended layer. The energy consumption for the fan drive for organizing the air flow, providing the phenomenon of fluidization of fruits and berries, as well as the costs for supplying heat to the dehydration object have been calculated. The energy consumption was determined for various options of energy supply: using a heat pump and due to the operation of thermoelectric heaters (TEH). It is found that the largest proportion of the energy consumption for air circulation organization. It has been established that from the energy point of view, of all the investigated freons, the refrigerant R410 is the most efficient, the total energy consumption for dehydration of 1 kg of irgi berries with it is 7102 kJ, for honeysuckle - 9765 kJ / kg, for lingonberry - 7989 kJ / kg. Comparative analysis revealed that the use of a heat pump installation of convective drying fruits and berries in the fluidized bed reduces the power consumption by an average of 13% in comparison with drying by using heaters to heat the coolant. |
