Depanning Coatings

Depanning Coatings
Ultrasonic Nozzle Systems for Applying Pan Release Coatings


Sono-Tek spray systems for applying depanning coatings feature rapid ROI and significant cost of goods savings in depanning oil for commercial baking manufacturing applications with easy retrofit and integration with existing plant conveyor systems. User friendly simple automated control and uniform coverage of pan release coatings improve process quality while providing a more environmentally friendly manufacturing solution in commercial baking.

Soya, Canola and other blended vegetable oils are applied as thin, uniform coatings of micron-sized droplets with no overspray of the material, resulting in a dramatic reduction in cleanup and atmospheric contamination. Sono-Tek systems are proven reliable for continuous high volume operation with significant reduction in energy costs and minimal service requirements, increasing production yields. With thousands of ultrasonic nozzle systems installed worldwide, we are a world leader in ultrasonic coating solutions.

Up to 80% reduction in material consumption compared with conventional spraying methods such as pressure spraying and spinning disc systems.
