Patent ID: 8025740

Claim:
Method for conducting, at predetermined time intervals, cleaning operations carried out in at least one of an inner chamber and a container of a fluid-receiving device of a foodstuff-processing apparatus, whereby at least one first fluid can be contained in the at least one of the inner chamber and the container, the method comprising: (a) determining at least one first degree of cleaning at at least one first moment in time of a first cleaning process; (b) determining at least one second degree of cleaning at at least one second moment in time of at least of one second cleaning operation subsequent to the first cleaning process; (c) determining a first difference between the first degree of cleaning and the second degree of cleaning; (d) at least one of determining and adjusting an action duration of a cleaning agent for at least one subsequent cleaning operation as a function of at least one of the first degree of cleaning, the second degree of cleaning, the first difference, and a cleaning speed in a first case, in which at least one of the following occurs: (i) the second degree of cleaning lies below at least one first degree of cleaning limit value, (ii) the first difference lies below at least one first difference limit value, and (iii) the cleaning speed lies below at least one first speed limit value; and (e) at least one of increasing a dosage of the cleaning agent and shortening a time interval between two subsequent successive cleaning operations in a second case, in which at least one of the following occurs: (i) the second degree of cleaning lies above the first degree of cleaning limit value, (ii) the first difference lies above the first difference limit value, and (iii) the cleaning speed lies above the first speed limit value.
