ABSTRACT:
Disclosed herein is an air agitation device that is positioned between two opposite sets of shelves on which the articles to be dried are placed.
The device constitutes two identical crankshafts, oriented in the same direction, that rotate in synchrony with respect to axes perpendicular to the opposite surfaces of the said sets of shelves.
To the crankpins of the said shafts are articulated, on opposite sides, two ventilation frames, each of which provided with a plurality of fins oriented suitably with respect to the said sets of shelves.
The synchronous rotation of the crankshafts renders movable each frame, which oscillates with a harmonic motion in two inter-perpendicular directions, one of which is coincident with the longitudinal axis of the passageway existing between the sets of shelves. The longitudinal harmonic oscillation of each frame causes, on the part of this, a flow of air directed alternately towards the upper and the lower part of one and the other set of shelves, respectively; the contrary occurs for the other frame.
