The OptiSet 4.1 Coagulation Detection System monitors the curd coagulation process within the vat to identify the “exact instance” of coagulation. Based on input from the cheese maker, the Recipe function on the control panel initiates the cutting of the coagulum when the optimum firmness is achieved. OptiSet also serves as a powerful diagnostic tool, helping the cheese maker to understand the effect of upstream processes on the “exact instance” of coagulation. The system reduces cost, maximizes yields, and provides better consistency from vat to vat.
