1.1 CT16 Toaster Functional Description

Bun Guide for Heel

and Crown Slots

Heated Holding Tray

The CT16 Toaster is designed to produce fresh, uniformly toasted buns on an "as needed” basis. The
countertop-mounted unit consists of a cabinet, a computer, a heating element and a pair of conveyor
assemblies.

When the unit is turned on, an electrical heating element (called a platen) is energized. The platen
heats up to a programmed temperature referred to as the setpoint. At the same time, both conveyor
assemblies are activated. When a bun is placed into one of the slots at the top of the cabinet, the
conveyor belts gently carry it through the unit, with the cut face of the bun passing over the heated
platen. As the bun passes over the platen, it is toasted. At the end of the process, the bun is deposited
onto a holding tray. The computer allows the operator to adjust the setpoint to obtain desired toasting
characteristics. Compression adjustment knobs also allow the operator to adjust the compression of
heels and crowns as they pass through the toaster.
