Pizza Hood Design Challenges

A pizza oven’s large size plus the heat and smoke they generate make effective

coverage a design challenge. Adding to this challenge are high production ovens

with “forced air baking.” These ovens can force hot air out of conveyor openings

and into the kitchen if the hood is not designed

correctly. Poor capture means higher energy

consumption.

Design Testing

Greenheck’s design engineers went to Architectural Energy’s Commercial
Kitchen Ventilation Lab to do testing to ASTMF1704 with Schleiren Flow
Visualization Technology. Schlieren imaging is an invaluable tool that allows us
to see airflow and heat transfer. Because we can see and identify what works
and what doesn’t we can design to provide optimum capture and
containment. Schleiren imaging is what led us to our design for the pizza hood.

Greenheck’s Pizza Hood

Our single island exhaust only canopy hood has a modified design to meet the unique requirements
of the pizza oven. We turned the filter bank perpendicular to the pizza oven. This allows for capture
and containment at both ends of the oven - creating a more comfortable working environment and
reducing energy costs.

The following chart shows some of the industries most popular conveyor ovens with the Greenheck
recommended hood size and cfm. For optimal performance Greenheck used a 12 inch overhang on all sides
that do not have a wall.
