Process and apparatus for controlling a controllable magnitude and use

A process and apparatus are disclosed for continuously determining the moisture content of a spoilable foodstuff, in particular, of grain and processed products of the latter, which is moved along a production line as a product stream and passed, at least in part, through a measuring section of a housing in accordance with the process, a pourable average of the product stream is created continuously within the measuring section, and the product moisture content of this product average is measured electrically on a continuous basis. In accordance with the device, the measuring housing has a capacitor as a continuous-flow measuring section and a device for continuously controlling the creation of a pourable product average. One of the central concepts of the invention is found in the interaction of the following factors: --continuous creation of a product average, continuous trickling-type flow of the product, with simultaneous electrical measurement on a continuous basis.

A process and apparatus are disclosed for continuously determining the moisture content of a spoilable grain product which is moved along a processing line as a product stream and passed, at least in part, downwardly through a measuring section of a housing in accordance with the process, a pourable average of the product stream is created continuously within the measuring section, and the product moisture content of this product average is measured electrically on a continuous basis. In accordance with the device, the measuring housing has a capacitor as a continuous-flow measuring section and a device for continuously controlling the creation of a pourable product average.

A method and apparatus for the cyclical counter-scavenging of filter hoses, particularly the control thereof, is disclosed. According to the present invention, the counter-scavenging of filter hoses is accomplished by gas blasts whose timing and duration are controlled by a fluid control apparatus. The fluid control apparatus consists of a drum distributor having an arm whose position controls the timing of the counter-scavenging blasts, and a valve whose activation controls the duration of the counter-scavenging blasts. The drum distributor and the valve are independently controllable by an electronic circuit including timing signals and control circuitry receiving the timing signals and converting these signals into activating signals for the drum distributor and the valve.

Process and apparatus for measurement of brightness of milled products, especially flour, are disclosed. The process is of the general type in which the surface of a layer of flour is illuminated, and the returned quantity of light is taken to an optical electrical transducer. A light source is used for illumination, and the light beam is optically decomposed into at least two part-beams (reference beam and measurement beam) for transmission to the transducer. At least one of the part-beams is cyclicly interrupted or broken into two essentially time-shifted measurement phases in such a way that of the two part-beams, only one of the two-part beams will strike the transducer during a first measurement phase, and during a second measurement phase at least the other part-beam will be applied to the transducer. The output signals of the transducer are taken to a memory which intermediately stores the output signals of one measurement phase until the output signals of the following measurement phase appear, so that both output signals can be taken simultaneously to an evaluating device for determination of the relative brightness value of the measurement beam in comparison to the reference beam.
