Abstract
The machine comprises a pre-heater followed by a first chamber, incorporating heated plates wherebetween a food product to be dried is passed. The machine also comprises a successive section, wherethrough the food product is conveyed to a second chamber, incorporating cooled plates, wherebetween the food product is passed. The plates are adapted for rapidly condensing moisture contained in the ambient air and in the food product itself, to further rapidly reduce its moisture content to approximately 13-14%.
Claims3
In a machine for drying pasta and the like food products comprising a pre-heater and a final drier, the combination of:
- a substantially vertical hot labirinth section arranged downstream of said pre-drier, said hot labirinth section including lateral delimiting walls encircling a hot labirinth chamber accomodating a first plurality of vertical plate means extending parallel to each other and laterally separating between each other hot treatment sectors;
- a first substantially horizontal connection portion having an inlet end connected to said hot labirinth section and an outlet end opposite to said inlet end;
- a substantially vertical cold labirinth section connected at said outlet end of said first substantially horizontal connection portion, said cold labirinth section including lateral delimiting walls encircling a cold labirinth chamber accomodating a second plurality of vertical plate means extending parallel to each other and laterally separating between each other substantially vertical cold treatment sectors;
- a second substantially horizontal connection portion having an own inlet end connected to said cold labirinth section and an own outer end, opposite to said own inlet end, connected to said final drier;
- conveyor means extending from said pre-drier to said final drier within said hot treatment sectors, said first substantial horizontal connection portion, said cold treatment sectors and said second substantially horizontal connection portion;
- wherein said first plurality of vertical plate means comprises tubular members flown by a hot fluid and said second plurality of vertical plate means comprises tubular members flown by a cold fluid for causing condensation of moisture present in the treated pasta and the like food products on said second plurality of vertical plate means.

In a machine for drying pasta and the like food products comprising a pre-heater and a final drier, the combination of:
- a subtantially vertical hot labirinth section arranged dowstream of said pre-drier, said hot labirinth section including insulated, lateral delimiting walls encircling an upwardly projecting hot labirinth chamber accomodating a first plurality of vertical plate means extending parallel to each other across said hot labirinth chamber and laterally separating between each other adjacent hot treatment sectors extending;
- a first substantially horizontal connection portion having an inlet end connected to said hot labirinth section and an outlet end opposite to said inlet end;
- a substantially vertical cold labirinth section connected at said outlet end of said first substantially horizontal connection portion, said cold labirinth section including insulated, lateral delimiting walls encircling an upwardly projecting cold labirinth chamber accomodating a second plurality of vertical plate means extending parallel to each other across said cold labirinth chamber and laterally separating between each other adjacent, substantially vertical cold treatment sectors;
- a second substantially horizontal connection portion having an own inlet end connected to said cold labirinth section and an own outer end, opposite to said own inlet end, connected to said final drier;
- conveyor means extending from said pre-drier to said final drier within said hot treatment sectors, said first substantial horizontal connection portion, said cold treatment sectors and said second substantially horizontal connection portion;
- wherein said first plurality of vertical plate means comprises tubular members flown by a hot fluid and said second plurality of vertical plate means comprises tubular members flown by a cold fluid for causing condensation of moisture of treated pasta and the like food products on said second plurality of vertical plate means.
