The main objective of a control system is to ensure that an adequate thermal process is delivered to the product. For this purpose a sensor is required for each variable, an indicator and recording system, control valves and a system for operating the valves correctly. The systems may be entirely manually operated or automatically controlled; alternatively, as in many cases with batch retorts, just one variable is automatically controlled, e.g. the temperature.
