Conveyor belt having rotating drive shaft
View Patent ↗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.
1. A method for processing food products, comprising:
conveying products for processing on a conveyor, supporting the conveyor along a path of travel, rotating a wave generating means comprising a cam means aligned for transversely oriented rotation relative to the path of travel and positioned at a lateral side relative to said path proximate to a lifting means; contacting the lifting means intermittently with the conveyor for displacing the supported conveyor and products along at least a portion of the path of travel to prevent the products from adhering to the conveyor and other of the food products on the conveyor during processing.
2. The method according to claim 1 , wherein the displacing the supported conveyor further comprises imparting an undulating motion to the conveyor.
3. The method according to claim 2 , further comprising varying amplitude and frequency of the undulating motion.
4. The method according to claim 2 , further comprising varying the frequency of the undulating motion.
5. The method according to claim 1 , wherein the processing comprises reducing a temperature of the food products.
6. The method according to claim 3 , wherein the reducing the temperature of the food products comprises subjecting the food products to a cryogenic substance.
