  • Method and arrangement for an enforced heat transmission between alimentary bodies and gases
    Patent number: 5316076
    Abstract: A method and arrangement for enforced heat transmission between a solid or liquid alimentary body and an ambient gas takes place in connection with cooling/freezing or when cooking, frying or drying the entire part or parts of the alimentary body. This method and arrangement uses a low-frequency standing sound wave. The apparatus uses a low-frequency sound generator having a pulsator part and a resonator part. The resonator part is acoustically virtually closed and is designed so that the alimentary body, which is to be exposed to enforced heat transmission, is located within a zone inside the resonator part where the standing sound wave has a particle velocity anti-node.
