Fruit-processing oven, particularly for converting raw plums into prunes by desiccation

摘要

An oven for converting raw plums into prunes by desiccation comprises an enclosure (1) with a double heat-insulated wall arranged as a tunnel and provided with air curtains (2 and 3) at its inlet and at its outlet. The air-agitation means recirculate a portion of the air within the enclosure, after filtration and condensation of water vapor on a cold wall. Electrical heating elements (65) are placed downstream of the device for condensing water vapor (60). The recovery duct (51) and blower duct (71) are placed laterally on opposite sides of the tunnel.
