Claim:
An apparatus for conveying products to be chilled or frozen without said products adhering to the apparatus or other products, comprising: a conveyor for transporting the products along a path of travel through refrigeration for chilling or freezing the products; a lifting bar disposed below and proximate to the conveyor for selective, intermittent contact with the conveyor to displace the conveyor from a plane of travel, thereby displacing the products on the conveyor to prevent the products from adhering to the conveyor or other of the products; a wave generating assembly adapted for rotation and having a cam arrangement for transversely oriented rotation relative to the path of travel for displacing the lifting bar at a lateral side relative to said path; a bearing surface on the lifting bar releasable engageable with the cam arrangement to displace the lifting bar to contact and displace the conveyor from the plane of travel; and drive means operatively associated with the wave generating assembly to rotate the cam arrangement for intermittently displacing the lifting bar.
