Principle
Middleby Marshall PS Series conveyor ovens bake both
faster and at a lower temperature than other ovens. Vertical
columns of hot air move heat aerodynamically instead of
using high temperatures. The streams of hot air remove
the boundary layers of cool heavy air which tend to insulate
the product. All Middleby ovens are designed to cook a
multitude of products including pizza, seafood, sandwiches,
bagels, ethnic foods and more.
