3.10 Adjusting the air flow in the drying zone
The positioning of the spread plates, guide plates etc. which control the air flow
will depend on a variety of factors, such as the size of the machine, whether it is
electrically or steam heated, the temperature and ventilation in the dishwashing
room etc. Therefore, it is not possible to give any precise figures. Instead trial and
error must be used in each individual case. Guidelines for standard machines are
given below.
The machine must be operating. When the air flow is set correctly, steam must
not escape from the infeed and outfeed openings and the temperature in the
tanks must remain constant. The figure shows parts of a drying zone and final
rinse zone in a machine where the feed direction is from right to left.

•
A=Final rinse zone
•
B=Damper plate
•
C=Drainage plate
•
D=Guide plate 1. The plate can be turned to guide the air flow towards the
infeed or outfeed, rotated through 180° and raised or lowered.
•
E=Spreader plate which can be moved sideways to increase or reduce the
gap between the plate and guide plates D and F.
•
F=Guide plate 2. The plate can be turned to guide the air flow towards the
infeed or outfeed, rotated through 180° and raised or lowered.

G=Drying zone

H=Fan
