Countertop conveyor ovens are ideal for convenience stores, sandwich shops or restaurants that want to quickly brown or cook sandwiches and pizza but may not do enough volume to require a large floor model. When selecting an oven, consider the conveyor size, interior clearance and conveyor speed. The width (or depth, depending on how you are facing the machine) of the conveyor indicates the size or quantity of food items you can set side by side and send through the cooking cavity at the same time. For each unit, the conveyor speed, and therefore the cooking time, is adjustable. Items that just need a quick browning or some cheese melted can be sent through faster than those that need to be completely cooked. Another adjustable feature is the interior clearance. Each unit has a plate at the beginning and end of the cooking cavity, which can be raised and lowered a couple of inches to account for taller products. In order to conserve as much energy as possible, it is recommended that the plate be set as low as possible, because excessive overhead product clearance is just allowing heat to escape.
