THE
TECHNICAL
CORNER
CHOOSING
THE RIGHT
DISHWASHER
When offering a dishwasher for sale or
as part of a fitting-out project, certain
factors should be considered to ensure
that the selected model is the most suitable
and that it meets the necessary
production requirements.
Assuming that the measurements for the
washing area are correct and sufficient for
installing the necessary appliances, the following
factors should be considered:
1 – Type and category of restaurant or
premises. This will give the average size
of tableware for each cover and the maximum
dimensions of the plates or trays to be
used, which will influence which machine to
choose.
2 – Average number of covers at peak times
and time available for washing up.
3 – True and theoretical performance of the
dishwashers. The personnel available for supervising
the dishwasher will influence the
true production time of the machine.
1. Type and category of restaurant or
premises
If you know the type of business or customer
for whom the machine is intended, and the
category of the restaurant, it is possible to
obtain some of the more significant data
used in defining the type of machine to be
offered.
On the one hand, you can obtain the average
size of tableware to be used at each service,
and on the other hand you can define the required
machine dimensions in order to take
the larger pieces of the tableware.
1.1 Calculating the average theoretical
production of a dishwasher
A preliminary step when selecting the right
dishwasher for an installation is knowing how
to calculate the theoretical production of a
dishwasher, given the different types of articles
in the tableware required for one diner
(plates, cutlery, glasses…).
The average production of a dishwasher is
based on a standard plate with a diameter
of 230 mm. Dishwasher production tables
are based on calculations using this type of
standard plate.
To calculate the required machine, each
article of tableware must be numerically
converted to a number of standard plates
measuring 230 mm. in diameter The different
capacities of baskets measuring 500 x 500
mm to take the various pieces of tableware
should be considered.
1.1.1 Dishwasher baskets
All tableware washed in industrial dishwashers
is placed in standard 500 x 500 mm
baskets, with different storages types and
shapes depending on the articles for which it
has been designed.
There are baskets especially for plates,
glasses, cutlery and trays, and multipurpose
baskets which will take any article, but without
the specific details required or needed
for a good wash.
Plate baskets have rows of tines which the
plates rest against, at a suitable angle in order
to receive the wash and rinse water.
Fagor Industrial’s plate baskets, called CP-
16/18, are so-called because depending on
the position in which the plates are stacked,
the distance between the tines varies according
to the direction, so that either eight
or nine rows of plates fit.
The angle at which the plate is inserted in the
machine depends on the depth of the plate,
and is important for ensuring that the wash
water hits the surface at the right angle. Flat
plates need less of a slope for the water to
wash across the surface, and therefore they
can be inserted in rows of nine, thus increasing
the capacity.
Tumbler and wineglass baskets have closed
compartments to prevent the glasses touching
each other and breaking. To adapt to the
diameters of the glasses, Fagor Industrial offers
baskets with 16, 25 and 36 compart-

ments (for diameters of 110 mm, 85 mm and
70 mm), each of which comes in three different
heights to adapt to the article in question.
Thus there are nine options for glassware.
