Ultrasonic Antimicrobial Coating Systems for Food Products
Sono-Tek ultrasonic spray systems are ideal for spraying small amounts of antimicrobial solutions directly onto food products such as prepared sliced meats to enhance product safety and extend shelf life. Uniform nanolayer antimicrobial solutions enable manufacturers to deposit very thin coatings not possible with other deposition methods.
Any Sono-Tek ultrasonic nozzle can be used to apply antimicrobial coatings. The WideTrack wide area coating system is commonly used to spray wide area substrates and moving webs of materials such as fabrics with nanolayers of antimicrobials. The thickness and concentration of coatings can be easily controlled and adjusted to maximize durability and efficiency. Several nozzles are used together to create any width needed, with high uniformity of the coating across the entire web.
Sono-Tek ultrasonic coating systems are unique, using patented ultrasonic nozzle technology to produce very small, uniform droplet that have a very tight drop distribution. The nozzle orifice is large compared to pressure nozzles, and is designed to be a non-clogging, pressureless spray device. This makes it possible to spray at a wide range of flow rates, and apply very thin coatings that are highly uniform, saving spray material and improving the quality of medical coatings while enhancing patient safety through more uniform antimicrobial coatings.
Benefits of Ultrasonic Spray Systems for Antimicrobial Coating:
- Self-cleaning ultrasonic nozzle prevents clogging
- Atomized spray is highly effective with minimal use of material (far less than soaking or other application methods)
- Uniform thin film ensures maximum effectiveness of applied material
- Flexible width control for various width substrates
- Can be configured for one side or dual side application
- Spray up or spray down capability
- Precise coating allows for uniform release of antimicrobial compound onto applied surface
- Wide range of flow rate capabilities

Nozzle systems for antimicrobial coatings can be integrated with WideTrack, Vortex, Impact and AccuMist air shaping systems. The type of nozzle and air shaping system used is application dependent. Often systems are customized to suit a customer’s particular application needs. Available configurations depend upon each application and can range from nozzle systems ready to integrate with existing conveyor and PLC controls, full turn key coating solutions, or customized systems designed to meet specific criteria. Sono-Tek works closely with customers to determine the best equipment for each application, providing full coating solutions.
