Sono-Tek Announces Initial Sale of New Industrial-Scale Ultrasonic Food
Coating System

MILTON, N.Y., June 1 /PRNewswire-FirstCall/ -- Sono-Tek Corporation (OTC
Bulletin Board: SOTK) announces initial sale of its first industrial-scale
ultrasonic food coating system. The system is based on Sono-Tek's proven
WideTrack platform currently used in many glass and textile manufacturing
lines worldwide. This unit was sold to Mesa Foods to replace a conventional
spraying system at the customer's baked goods facility in Louisville, KY.

This ultrasonic spray coating unit is used to uniformly coat a micronic layer
of edible oil on formed dough prior to baking. The advantages of the
ultrasonic food coating system are numerous: improved final product quality in
uniformity of color and taste, reduced cost of goods by using less oil, and
enhanced safety due to improved sanitary and environmental conditions at the
manufacturing plant. The system had been installed and operating at the
customer's facility in production capacity for over five months prior to the
sale.

The new WideTrack ultrasonic food coating system is comprised of an array of
ultrasonic nozzles positioned over the food preparation line with computerized
control and an integrated pumping system. The control system regulates the
flow of liquid required according to the speed of the line and the performance
requirements of the liquid coating to achieve precise, uniform deposition of
the desired amount of liquid. The ultrasonic vibrations of the nozzles provide
a self-cleaning mechanism and as a result the nozzles never clog. In
addition, the system uses dramatically less liquid than traditional air
pressure spraying systems or spinning disk technologies. The system can be
configured for a variety of widths, up to 120 inches and beyond if needed.

Sono-Tek CEO, Dr. Christopher L. Coccio states, "Sono-Tek's WideTrack
ultrasonic food coater offers the food industry key advantages in enhancing
productivity and product performance with a very fast ROI. We are very excited
about the potential for our ultrasonic food coating systems as the industry
becomes familiar with this game-changing technology. Not only baked goods
manufacturers, but also producers of frozen and refrigerated meals, dairy and
meat products, as well as manufacturers of spices and flavorings, and even
producers of food packaging films and environmentally-friendly compostable
trays are now able to benefit from the advantages of our green technology."

Sono-Tek will be presenting our ultrasonic technology systems at the upcoming
annual conference and EXPO of the Institute of Food Technologists (IFT) in
booth #1178, Anaheim, CA, in June 2009. Contact us via email at
