Apparatus for coating food products with sauce

Abstract

An apparatus for coating food products with sauce while simultaneously deep freezing them comprises a rotatable drum (10) in a horizontal position, on the inner wall surface of which a driving plate is disposed and which has an opening (16) at an end face. The apparatus furthermore comprises a second opening (18) on the opposite end face, an ejector, which is provided at the driving plate (88) and disposed in front of the second opening (18), a nozzle (80, 84, 86), mounted in the first opening (16), for feeding a coolant, particularly in the form of liquid nitrogen or liquid carbon dioxide, into the drum, a further nozzle, mounted in the first opening (16), for injecting sauce into the drum, an exhaust pipe, which occupies essentially the whole cross sectional area of the first opening (16) and is intended to exhaust gaseous coolant, as well as a movable holding device (42, 44), which accommodates the exhaust pipe (34, 28) and permits the exhaust pipe to be moved between a position immediately in front of the first opening and a retracted position.
