Abstract

The present invention relates to a processing system (0) intended to dehydrate food waste (4) comprising at least one device (200) for storing and heating food waste (4) comprising at least one device for stirring the food waste (4), a direct contact heat exchange condenser (34) comprising an opening (37) for extracting incondensable gases from the condenser (34), a first pipe (3) allowing direct communication between the storage device (200) and the condenser (34) to allow the passage of gaseous effluents (22) particularly comprising steam, produced by the heating of said food waste (4) in the waste storage and heating device (200), to the direct contact heat exchange condenser (34), where the steam condenses in contact with a shower of the coolant liquid. The recycling of heat between the condenser (34) and the device (200) for storing and heating food waste is provided by a heat pump (6).
