IMPROVEMENTS IN OR RELATING TO THER DETERMINATION OF PROCESSING LOSSES OR GAINS IN A CONTINUOUS LIQUID PROCESS

摘要

Method and apparatus for providing substantially instantaneous reading and recording of processing losses and gains from a continuous liquid chemical process, such as refining of vegetable oil. The product inflow into and the product outflow from the process are separately and continuously measured. The measuring device is used to generate electronic pulses corresponding to the measurement, preferably at a rate in the order of, typically, about one hundred pulses per pound of liquid. High speed pulse counters electronically count these pulses, and gate means is actuated each time the pulses coming from either pulse stream reach a total of, say, 10,000. Then, the total count needed for the other pulse stream to reach the same total is determined and is displayed in terms of processing gain or loss percent, to the nearest tenth of 1%. Both counts then start over, and the counting cycles go on continuously. Temperature and moisture corrections may be applied, and an averaging or pulse selection system may be employed to avoid recording or displaying the instantaneous fluctuations that occur within the process system, thereby smoothing out the variations from the average or basic flow rates.
