MODELING AND DYNAMIC ANALYSIS OF A CONTINUOUS WHIPPING SYSTEM

In order to clarify the mechanism of the cycling phenomenon in a conti nuous whipping system, the dynamic model has been developed. The model involves the kinetics of whipping in the dasher and the flow characte ristics of whipped cream in the discharge pipe which is connected with the dasher. The whipping rate has been expressed by an autocatalytic- type equation in terms of whipping index defined here using the firmne ss of whipped cream. Numerical simulations based on the proposed model lead to the conclusion that the cycling phenomenon is caused by the i nteraction between the whipping rate in the dasher and the flow charac teristics of whipped cream in the discharge pipe, because both are dep endent on pressure.
