Ultrasound Processor

Developing food products

General description

The power ultrasound can homogenise samples, break particles and cell walls and cause other physicochemical reactions. It can be used in extraction processes and other product developments. (N.B. Power ultrasound is different from diagnostic ultrasound that is used for imaging).

Technical description

The high-intensity ultrasound processor (sonicator) delivers 20kHz power ultrasound into liquid media. The liquid can contain solid particles. It has two different probes for small and large samples (up to 1000 ml). The power ultrasound can homogenise samples, break particles and cell walls and cause other physicochemical reactions. Jacketed beakers and and a chiller are added to this equipment to control temperature during the processing as sonication can increase the sample's temperature. The amplitude of the sonication can be adjusted (0-100%) and the equipment can show real-time and accumulative power delivery.
