Prototype Aqueous Dryer System

      Described is a dryer designed to effectively dry precision
parts.  The dimensions (of a lab scale model) of the dryer, are as
follows:  23 inches in depth by 17 inches in width by 23 inches in
length.  The sides or walls are made out of half-inch plexiglass.

      There are seven air-knives in the dryer pointing at different
angles to ensure that the heated air being dispersed will cover the
entire surface area of the parts. Six of the seven air knives are 15
inches in length and are spaced about three inches apart from each
other on the sides of the dryer.  The seventh air knife is located in
the center at the top of the dryer.

      An advantage of the dryer is that it gives rapid, thorough
drying of complex shaped parts after water cleaning due to its
design.  The dryer unit is very effective in drying critical disk
drive components after they have been cleaned with the aqueous
process.

      The air supplied to the air-knives is 'Clean Room Supply Air'
and is heated by steam to 140 degrees Fahrenheit.  The air velocity
can be changed by varying the air pressure from 0 to 75 psi.  The
unit is exhausted through house exhaust to control humidity inside
the enclosure.  Also included in the dryer is an automatic turntable
device to rotate the parts during the drying process.  The dimension
of the table is 9.5 inches in diameter in the prototype dryer.
