The VIEW Magazine ControlNews Catalogs Manuals On-Line Automation Bookstore Pub. Inc. Implements ControlLogix Processor in Dairy Processing Facility. Application Overview Dairy processing facilities need to maintain a high level of uptime due to the constant flow of milk from the dairy producers. This becomes even more complicated when the product is perishable.
Milk coming into the facility is also inconsistent in fat and protein amounts.
This inconsistency needs to be corrected or standardized to achieve the consistent final product, in this case, natural cheese. This specific application required the Rockwell Automation system to control the transfer of raw milk to pasteurizers, the pasteurization process, and transfer of the milk product to the cheese vats. ControlLogix is also used to control the cheesemaking process, the transfer of curd and whey to the curd matting belt, and whey processing streams including separation, cream heat treatment, and whey heat treatment. The ControlLogix5550 controls all PID loops for pressure, flow, and temperature control. ESE has found this is a critical component of any successful controls project and minimizes misunderstandings during the project.
