A plurality of protuberances are integral with the base substrate and project from the upper generally planar surface and are arranged in substantially evenly spaced relation and define a pair of spaced rows so as to collectively define an elongate space between the rows. Oil may be sprayed onto food products and tumbled in a drum 16 which both rotates and moves in a reciprocating manner with the conveyor tray 14. In order to rapidly transmit the rendered pages of print data across the low bandwidth connection the computer applies data compression to the print data. Training data for the ML method can come from any suitable source or combination of sources.
