BERRY DRYING HEAT PUMP UNIT Russian patent published in 2015 - IPC F26B9/06 F26B23/10 

FIELD: heating.

SUBSTANCE: in a heat pump unit a provision is made for the simultaneous control of the temperature of a drying agent and the temperature of shelves of the shelf stand, on which berries (product) being dried are located. The drying agent temperature control is performed due to the connection to the composition of a cooling machine of an external capacitor parallel to an internal capacitor and a temperature sensor installed at the internal capacitor drying agent outlet. Shelves temperature control is performed due to the introduction of a utilisation heat exchanger for heating of an intermediate heat carrier, a three-way valve at the shelf stand heat carrier inlet and the temperature sensor at the shelf stand heat carrier inlet. The invention shall provide for the enhancement of the technological drying process due to the simultaneous temperature control of the drying agent and berries during the drying process.

EFFECT: reducing the time required for berry drying.
