Functional Zones:
Considerable reduction in detergent consumption is
achieved by diverting part of the fresh rinsed water
(220litres/hour) to the pre-wash tank, with the remaining
being used for the regeneration of the main wash tank.
The water that is diverted to the pre-wash tank is then
pumped to both the upper and the lower arms to pre-clean
the soiled products, ensuring that larger food particles and
liquid residues such as gravy and sauces are washed from
the items, thereby reducing greatly the soil level on the
items entering the machine’s main wash tank. An optional
Eco pre-scrap arm positioned just after the inlet in the
pre-wash tank, will immediately start to “soften” and “wet”
items as they enter the machine so it is especially useful
to wash heavily soiled items or when the machine is used
mainly on fast speed.
The water in the main wash tanks is pumped with detergent
and is sprayed over the items from both the upper and
the lower wash arms, guaranteeing a uniform distribution
of the washing solution and allowing all the areas of the
washing chambers to be covered. An option of variable
pressure gives the possibility to increase up to 30% the
pressure towards the lower wash arms and at the same
time to slow down the belt speed in order to better wash
boxes or heavily soiled items.
Rinse area equipped with the DUO-rinse system: the first
rinse arm is filled with re-circulated rinse water to eliminate
any trace of detergent, while the second ramp is filled with
hot clean water to guarantee the sanitation of the items.
A drying section with inspection door (1100 mm wide) will
be provided as an integral part of the machine. This allows
the operator to remove practically dried items immediately,
without them being too hot to handle.
Optional Energy Saving Device (ESD) utilizes heat and
steam generated from the machine to pre-heat the
incoming water. This reduces energy consumption by
13 kWh by eliminating the need for an external boiler
or water heater and allows the machine to be supplied
with cold water up to 10° C. In addition, the double pipe
in the optional Water Heat Exchanger will have a further
energy saving of about 2 kWh as a result of the exchange
in temperature between the used rinse water and the
incoming fresh water.
Thanks to the Energy Saving Device, the outgoing air from
the machine will be cooler and less humid, eliminating the
need for a ventilation hood, if the incoming water is about
10 °C and the room has frequent air changes or is well
ventilated.
Optional Heat pump operating in conjunction with the
Energy Saving Device plus the Water Heat Exchanger, will
heat up incoming cold final rinse water up to 65 °C before
entering the boiler.
The introduction of the Heat pump system allows 19
kWh of energy savings; also the heating element in the
boiler can also be reduced by 8kW. The exhaust air will
be cooled down to about 15°C with very low humidity so
that no ventilation hood is needed over the machine.
Construction:
304 AISI stainless steel frame, door, strainers, wash and
rinse arms.
No legs in loading area (700-1.100 mm).
Wash tanks in 316 AISI acid proof stainless steel with
rounded corners to facilitate cleaning.
Double-skinned construction and insulated counter
balanced doors provide silent operation and low heat
emission.
Wash/rinse arms and filters easy to remove.
Double tank filters (flat and deep box) cover the entire
width of the wash tank.
Simple service from the front.
Operation:
The conveyor belt is driven by means of a gear motor
which will be protected against overcharge (as a result
of blockage or for any other impediment), by a safety
device mounted at the end of the unloading side.
Individual drain valves for each tank. Drain valves are
automatically closed when the door is closed, so there is
no risk of tank filling with open drain valves.
Counter balanced doors with safety switch and easy-to-
grip handle.
The machine incorporates a safety stop switch at the top
of the discharge section which will automatically stop
the conveyor in case that dishes, trays, containers, etc…
have not been removed after cleaning.
Flat panel with electronic control that, thanks to the auto
diagnostic control and the 32 digits window, is able to
communicate in every moment, the working conditions
of the appliance.
Electronic control panel incorporates the plug-in
connection to link basic and integrated HACCP systems.
Pre-arrangements for external automatic detergent
dispenser.
Two speeds, a fast speed for normal soiled items and
a slow speed for heavily soiled items. As option the
machine can be equipped with three variable speed
selector: normal speed, slow speed for heavily soiled
items and a third speed for 2 minute contact time
according to DIN 10510. Each speed is individually
adjustable.
