CONCEPT OF AIR IMPINGEMENT COOKING
The “AIR DECK” Oven produced by GARLAND COMMERCIAL
INDUSTRIES, INC ., utilizes a revolutionary cooking concept,
called “AIR IMPINGEMENT” . It provides exceptional baked
food product quality in far less time than conventional
devices on the market . The “AIR IMPINGEMENT” system
directs a high velocity stream of heated air at the food
product being baked . This blast effect penetrates the
boundary layer of air encircling the product and heats the
food more efficiently, because the air concentrates heat on
the food product . Greater heat transfer rates, which results in
products baking two to four times faster than conventional
means, are possible with “AIR IMPINGEMENT” .
The AIR IMPINGEMENT” process develops the high velocity
air stream with a specially designed fan that draws super-
heated air from a heat source (either gas or electric) . This
air is directed through a plenum chamber to patented “JET
PLATES” which have hundreds of focused jet ports that
“impinge” the heated air onto the food product surface . The
heated air is re-cycled to the heat source after striking the
food product, thus reducing energy consumption .
The “AIR IMPINGEMENT” process is tolerant enough for
sensitive food products and effects proper crispening and
even browning of such products as they pass through
the oven, because air is the medium which heats the food
product . The adjustable air controls for top and bottom jet
plates allow further enhancement of cooking .
