Ultrasonic food processing involves a vibrating knife producing a nearly frictionless surface which does not deform food products and to which they do not stick. The surface cleanly cuts or slits products including fillers such as nuts, raisins, dried fruit or chocolate morsels without displacement or plowing.
Consumer Report
One Dukane customer found that by using ultrasonic food cutting they could run an entire order without stopping to clean their cutting blades. Before incorporating ultrasonic food processing in their production operations, the line had to be stopped every 45 to 60 minutes to remove product stuck to the cutters. This made it necessary to mix small batches to accommodate the required cleaning cycles. This caused batch to batch variances and much product scrap.
