Sono-Tek Announces Industrial Food Coater Sale

MILTON, N.Y., July 14 /PRNewswire-FirstCall/ -- Sono-Tek Corporation (OTC
Bulletin Board: SOTK) today announced the sale of a new industrial depanning
oil coating system, the SonoCoat PAN.

The equipment was developed for a global baked goods conglomerate which owns
and operates numerous baking plants. The system has the potential to become
the standard operational unit at the customer's baking lines worldwide,
replacing current conventional spraying system technologies.

The sale is the culmination of successful, rigorous testing at the customer's
plant, where Sono-Tek's new equipment demonstrated savings of 45% of the
depanning oil currently being used by the customer, with an estimated return
on investment of less than six months.

The non-clogging ultrasonic spray created with Sono-Tek's patented nozzle
technology has several advantages over older, conventional spraying systems.
One unique advantage is superior transfer efficiency. There is less bounce
back of liquid from the target, combined with a controllable, uniform coating
application of nano to micron thickness layers. Other advantages include tight
drop distribution for even coatings and minimal maintenance requirements of
the equipment. These technical advantages are of significant economic value
for the food industry in general, and for the baked goods industry in
particular.

According to Dr. Joseph Riemer, Sono-Tek's President, "Sono-Tek also recently
announced the sale of an edible oil ultrasonic spray coating system to Mesa
Foods of Louisville, KY, and is now developing and testing additional
applications for baked goods clients, including ultrasonic spray coating of
anti-microbial solutions and moisture barriers for product safety and shelf
life extension, as well as ultrasonic spray coating of eggwash and glazes for
decorative purposes."

Sono-Tek's patent pending ultrasonic spray coating applications for the food
industry are based on technology transfer from the Company's successful
experience and expertise in medical device coating (cardiac stents), and more
recently in the field of advanced energy -- fuel cell membranes and solar
panels.

These new ultrasonic food coating systems are available to food manufacturers
for evaluating the compatibility of their liquid coating needs with ultrasonic
atomization technology. These needs can be tested in a continuous, pilot plant
setting at Sono-Tek's laboratory as well as in a full scale industrial
capacity at the client's manufacturing plant. Sono-Tek Corporation provides
food manufacturers with state-of-the-art tools for product and process
development not available elsewhere with significant savings when compared to
conventional spraying processes.
