Cold water final rinse for glasswashers

For glasswashers (available at M-iClean UM), final rinsing in programmes I and II is
not carried out with hot (65°C) water, but with fresh water that is not heated.
Note
When the programme is changed from a hot final rinse programme to programme I
or II, it takes approximately 3-4 programme runs for the final rinse programme to be
performed with cold water.
When the programme is changed from programme I or II to a programme with hot
final rinse, the required temperatures are reached in the same programme run.
Programme I (short programme cold)
The glasses are cleaned with a rinsing temperature of 55°C. Then follows the final
rinse with unheated fresh water.
The cooling of the glasses can lead to temperature stresses in the glasses, which
require additional caution!
These glass temperatures can be assumed at a temperature of approx. 10°C for the
incoming water:
•
Approx. 22-27°C immediately after removal
•
Approx. Room temperature, 1-2 minutes after removal
•
Approx. 30-35°C for thick-walled glasses (beer mugs), immediately after re-
moval
To ensure that the rinsing temperature of 55°C is reached, the machine has an ex-
tended running time. This means that the programme runs until the water is heated
to the required temperature (however, for a maximum of 5 minutes).
Programme III (Intensive hot programme)
The glasses are cleaned with a rinsing temperature of 60°C. The final rinse is then
carried out with fresh water heated to 65°C. The described extension of the running
time also ensures that the required temperatures are reached in Programme III.

Disinfection control

Caution
Glass corrosion and loss of decorations due to high water temperatures and
long wash cycle times
•
Make sure that the dishes and glassware used are suitable for the high stress
placed on them.
MEIKO offers two types of machine with thermal disinfection for institutions with ad-
ditional hygiene requirements. Both versions have greater heating performance in
the wash tank than standard machines.
A control

The term A refers to a way of measuring how microorganisms are eliminated by
0
moist heat disinfection methods. By using a moist heat disinfection method, it is ex-
pected that a specific temperature over a period of time has the effect of eliminating
a predictable number of microorganisms with a particular resistance.
The standard setting for a dishwasher with A
•
The tank temperature during washing is up to 74° C.
•
For tank temperatures of 65° C or higher, each tank temperature is assigned a
factor.
