MOISTURE DETECTING AND CONTROLLING DEVICE FOR GRAIN PROCESS PLANT

摘要

PURPOSE:To reduce the number of hardware components by selecting detected values from a plurality of moisture meters in a previously set order with the use of a single control device, and by feeding them to processing devices. CONSTITUTION:Moisture meters 24 attached with temperature sensors 28 for rice pearling mills 12, 14, 16, an weighing unit 18 and the like, are connected to the input side of the multiplexer 70 of a control device 26, and an input port 64 is connected to the output side thereof while an output port 66 is connected to a control terminal 70A. Detected moisture values and detected temperature values are delivered to the multiplexer 70, and a control signal is delivered thereto through the port 66 so that the multiplexer 70 selects the detected moisture values and temperature values which have been delivered, in a predetermined order in accordance with the control signal, and delivers them through the port 64 in time series. In this case, the rates of detection of moisture and temperature are slow in comparison with the process speed of the control device 26 which can be therefore used as a single controller common to respective moisture meters 24, thereby it is possible to reduce the number of hardware components.
