B. Component Function
1. Oven Controller
The controller controls all functions of the oven. The cooking temperatures can be set from 200F
to 900F (93C to 509C). Cooking times (conveyor speed) can be set from 1:00 minute to 60:00
minutes on the DZ33I.
Controller features a self-cleaning mode, a programmable automatic ON/OFF timing mode, and
an energy conserving standby mode. Also included is a service mode designed to assist the
service technician.
The Menu Select control contains 10 menu keys which can be preset to control both oven
temperature and cook time. The operator must then press only the menu key for the desired
product being cooked.
2. Infrared Heating Panels
Heating panels are positioned above and below the conveyor belt in the oven chamber
(figure 1-3). When energized these panels emit infrared long waves. These waves do not heat the
air through which they pass. Instead the waves are absorbed by the outer surface of the product
transported through the oven on the conveyor belt. Using this application, food is placed on the
conveyor and the unique properties of the infrared waves cause it to cook from the outside to the
center in traditional fashion.
