METHOD FOR EVALUATING AND GUARANTEEING THE THERMAL HYGIENIC EFFECT IN A MULTITANK DISHWASHER
First Claim
1. A method for evaluating and guaranteeing a thermal hygienic effect in a multitank dishwasher, the method comprising:
- providing at least one sensor in the multitank dishwasher, the sensor transmitting a temperature within individual treatment zones to a machine control system, in particular a control system of the multitank dishwasher;
determining, via the control system, the thermal hygienic effect upon the items to be cleaned via the influencing temperature and time on the basis of heat equivalents; and
controlling a rinsing process such that a defined, predetermined quantity of heat equivalents is transferred to the items to be cleaned.

Abstract
A method for evaluating and guaranteeing a thermal hygienic effect in a conveying dishwashing machine preferably a multi-chamber dishwasher, is provided. The inventive dishwasher is provided with one or several sensors which are fixed therein and transmit a temperature inside each treatment areas to a machine controller, preferably a controller for the conveying dishwashing machine. The machine controller determines the thermal hygienic effect by means of heat equivalent-based temperature and time acting on a cleanable object. A washing process is controlled in such a way that predetermined quantity of heat equivalents is transmitted to the cleanable object.
