Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A process for drying hydrophobic articles comprising: (a) positioning a wet article within a drying zone; (b) placing protruding stud members of a carriage in contact with upwardly extending cavities defined in the irregularly shaped undersurface of a wet article; (c) moving the carriage upwardly to lift the article from the drying zone into a spinning position; (d) spinning the article by rotating the carriage at such speed sufficient to expel any liquids therefrom by centrifugal force; (e) gathering the liquids expelled from the hydrophobic article by the location of a cylindrical liquid gathering surface around the article in the spinning position; (f) returning the article to the drying zone therebelow by moving the carriage downwardly out of contact with the article; and (g) removing the article from the drying zone.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
The process as defined in claim 1 further including aligning the article after spinning to facilitate proper orientation within the drying zone.
Claim 4
Dependent Claim
39 words
The process as defined in claim 1 further including braking said spinning of the article prior to return of the article to the drying zone to cause rapid deceleration of the rotational velocity of the carriage and the article.
Claim 5
Dependent Claim
18 words
The process as defined in claim 1 wherein said spinning is performed at approximately 1750 revolutions per minute.
Claim 6
Dependent Claim
17 words
The process as defined in claim 1 including stacking the articles after removal from the drying zone.
