WHY

A

DOUGH

DOCKER?

Middleby Marshall exclusive and patented Dough Docker (SD-21P) ends the "blistering"
problems found in many operations today. Our Dough Docker virtually eliminates the
need to "pop" blisters in the dough while baking. BENEFIT: No loss of oven heat due to
opening of the oven doors; no labor loss and insures crispier crusts with a "homemade"
appearance with 100% perforation...a must for conveyor ovens.

Our research has made this perforator completely compatible for "thick-n-thin" pizza
doughs. The Middleby Marshall SD-21P eliminates hand docking and the use of

extra utensils. No need for additional counter space that requires an extra
operator for the manual perforation operation. Speeds up your operation,
too! And, most important, the size of the perforated hole has been designed
to eliminate leakage of sauce and other condiments thus assuring complete
product consistency and more profits for you.
