The egg tray conveyor carries those wet products through a drying oven where most of the balance of water content of the products is evaporated off by means of re-circulating hot air until the products have only 8% moisture left.
The egg tray drying section consists of a direct-fired natural gas (or oil) re-circulating air dryer with a pass conveyor carrying the wet products through the heated dryer tunnel. An endless chain conveyor system conveys them through in the dryer tunnel while re-circulated hot air is blown from the top through the layers. The dried egg tray are then discharged to an unloading conveyor where they are automatically stacked, counted.
