TrolleyFreeze from York International is designed to freeze or chill packaged or unpackaged food product. Multiple independent trolley lanes on the semiautomatic tunnel accommodate simultaneous processing of products requiring different retention times. Manually loaded dollies or trolleys are hydraulically conveyed though the freezing cycle via carrier chains. Low temperature air is circulated in an alternate reversing airflow pattern at high velocities for rapid temperature reduction.
