Process for conducting cleaning operations in a fluid-receiving device of a foodstuff-processing apparatus, and fluid-receiving device and foodstuff-processing apparatus therefor

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.
