Abstract
Equipment for use in washing articles such as egg trays and the like wherein the articles after being washed are moved by a conveyor to a drying zone for being picked up by a rotatable carriage by which they are lifted into a hood and rotated at high speed to discharge water or other washing liquid therefrom. The movement of the conveyor and the rotation of the carriage are coordinated to start and stop the rotation of the carriage so as to dry one article after another as it is advanced to the drying zone and onto the carriage by the conveyor. The rotatable carriage includes a system for orientation of the trays or the like for discharge to the conveyor and a brake assembly for quickly decreasing the rotational velocity of the carriage.
Claims8
For use with a conveying system or other similar transferring device, an apparatus for drying articles comprising:
- a. a drying zone for receiving at least one wet article to be dried traveling along a conveyor system;
- b. a vertically and rotatably movable carriage assembly positioned below said drying zone and adapted to move upwardly to lift and move the article above the conveyor;
- c. a rotational control means secured to said carriage assembly and adapted to cause rotation of said carriage assembly and to increase the rotational velocity of said carriage assembly to expel liquid from the article to be dried, said rotational control means also adapted to decrease rotational velocity and stop rotation of said carriage assembly to allow replacing of the article on the conveyor;
- and
- d. a vertical moving means for selectively causing said carriage to move into contact with the undersurface of the article located in said drying zone on the conveyor and vertically move the article to a position above the conveyor.
