Abstract: In this paper mention different method of temperature control. The main purpose of this work is to control pharmaceutical reactor process & its temperature by analyzing reactor process we conclude that the main thing is temperature control of reactor. In this paper mention different method of temperature control which is used in food, chemical & process industries. In these industries they used different types of method (closed loop control system, proportional control system, proportional-integral-derivative control system,and proportional-integral-derivative control system) as per their application. By studying many paper we conclude that PID control method is most suitable for the temperature control of reactor.
