This paper describes the automatic control device of pasteurized mix in the ice cream production process.We design
a scheme of control system using FBD program language and develop the programmer in the STEP 7-Micro/WIN
software, check for any bugs before downloading into PLC .These developed devices will able to provide flexibility and
accuracy to control the step of pasteurized mix. The operator just Input the duration and temperature of pasteurized mix
through control panel. All the steps will finish automatically without any intervention in a preprogrammed sequence
stored in programmable logic controller (PLC). With the help of this equipment we not only can control the quality of ice
cream for various conditions, but also can simplify the production process. This control system is inexpensive and can be
widely used in ice cream production industry.
