Ultrasound assisted drying technology for food processing
Innovative ultrasound technology enhances drying efficiency by using acoustic fields to drive moisture to field nodes, improving diffusion rates. Ideal for integration with existing drying methods to optimize food processing.
Overview
The ultrasound assisted drying technology is an innovative approach to improving the efficiency of food processing. By utilizing ultrasound radiation pressure, this technology enhances the diffusion rate of moisture within food products. The process involves creating a standing wave acoustic field that strategically drives moisture to field nodes, which can be positioned at or outside the surface of the product. This method is particularly effective when combined with traditional drying techniques, offering significant improvements in drying efficiency and product quality.
Technical specifications
- Ultrasound radiation pressure: Utilizes acoustic waves to enhance moisture diffusion.
