Abstract
An apparatus and method for processing products by chilling or freezing includes a conveyor for conveying the products along a plane of travel; lifting means disposed for intermittent contact with the conveyor during processing; cam means rotatable for contacting and displacing the lifting means to contact and displace the conveyor from the plane of travel, thereby displacing the products on the conveyor to prevent the products from adhering to the conveyor and other of the products; and drive means operatively associated with the cam means to impart rotational movement to the cam means for intermittently contacting and displacing the lifting means.
Claims14
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.
An apparatus for conveying food products to be processed, comprising conveying means for conveying the food products along a path of travel for processing;
- lifting means operatively associated with the conveying means for displacing the conveying means vertically from the path of travel at select intervals uniformly across a width of the conveying means;
- cam means adapted for transversely oriented rotation to contact and impart a lifting force to the lifting means at a lateral side relative to said path and at the select intervals for providing an undulating motion to the conveying means at the select intervals:
- and drive means connected to the cam means for transmitting a drive force to the cam means for rotational movement of the cam means.
