PROCESSING SYSTEM INTENDED TO DEHYDRATE FOOD WASTE

摘要

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).

1. A treatment system (0) intended for dehydrating food waste (4) including at least:
a storage and heating device (200) for food waste (4) comprising at least one device for stirring food waste (4) in a container (2), a condenser (34), a first pipe (3) allowing direct communication between the storage device (200) and the condenser (34) to allow passage of gaseous effluents (22) comprising steam produced in the storage and heating device (200) by the food waste (4) toward the condenser (34) where the steam contained in the gaseous effluents are condensed,the inside of the container (2), the inside of the enclosure (35) of the condenser (34) and the inside of the first pipe (3) are maintained under primary vacuum, wherein the condenser (34) is a direct contact heat exchange condenser (34) having an enclosure (35) comprising an incondensable gas extraction opening (37) in the upper portion of the condenser (34) and a condensate extraction opening (36) in the lower portion of the condenser (34).
