The way of automatic control of potato starch drying by means of steering revolutions of vacuum dehydrator has been worked out and described. A special electronic worm sensor for the continuous measurement of starch humidity has been designed and constructed. Humidity of starch was determined by measurement of its conductance. The influence of temperature upon the humidity measurement was compensated in an electronic system by means of a thermistor. The system for automatic control of starch drying is characterized by the following parameters: measuring range 17–23% H2O; accuracy of measurement and control of humidity η0.3% H2O. 相似文献
