Temperature Control Of The Ohmic Heater

Ohmic heating plants are supplied with a fully automatic feed-forward temperature control system. Pure feedback is not satisfactory due to the time constant in the heater column.

Inlet changes, which will affect the final product outlet temperature, are changes in inlet temperature, mass flow rate and product specific heat capacity. In the feed-forward control system, a microprocessor scans these variables including the latter, which is an operator-entered or computer-generated variable. It continuously computes the electrical power required to heat the product and compares this value with the signal from a power transducer on the output side of the transformer. Feedback monitoring is used to prevent any long-term drift in outlet temperature.
