Abstract
The present disclosure consists of a drying tunnel for fruits or vegetables which comprises an impulsion and heating chamber and a plenum, configured for receiving an outgoing hot air generated in the impulsion and heating chamber by the generator, so that the plenum comprises openings arranged in a staggered pattern, located on the lower surface thereof, with an opening density between 150 to 300 openings per square meter, wherein said openings are configured for expelling a distributed hot air from inside the plenum in a perpendicular way towards a conveyor system, configured for moving fruits and vegetables to be dried.
Claims9
A drying tunnel for fruits or vegetables comprising:
- an impulsion and heating chamber;
- and
- a plenum, configured for receiving an outgoing hot air generated in the impulsion and heating chamber;
- wherein the plenum comprises:
- openings, with a cross-section shape selected from the group consisting of circular and oval, arranged in a staggered pattern, located on a lower surface of said plenum, with an opening density between 150 to 300 openings per square meter;
- wherein said openings are configured for expelling a distributed hot air from inside the plenum in a perpendicular way towards a conveyor system, configured for moving fruits and vegetables to be dried;
- wherein the plenum comprises a rectangular cross-section decreasing along the length thereof, as it moves away from the inlet of the outgoing hot air from the impulsion and heating chamber;
- and
- wherein said decreasing rectangular cross-section is configured for maintaining the pressure conditions inside and releasing distributed hot air under the same pressure and temperature conditions throughout the entire conveyor system, achieving a uniform flow distribution over all the openings by means of the geometry of the plenum.
