Abstract: A continuous steady state flow process for converting proteinaceous materials by reacting the proteinaceous materials with coagulants or other precipitants in situ. Streams of proteinaceous materials and coagulants are fed into an introduction chamber under a predetermined pressure and are directed through an orifice as a high velocity jet stream into a resonance chamber to impinge against a vibratile element. The energy from the jet stream is transferred to the vibratile element to cause it to vibrate at high sonic or ultrasonic frequencies. The high sonic or ultrasonic energies are transferred to the mixture of proteinaceous materials and coagulants to produce a cavitational effect and cause instantaneous reaction and homogenization of the proteinaceous materials and coagulants to thereby form a protein matrix.
