Count Weight Analizer

The “family” of weigh-count analyzers consists of two different units, a laboratory unit and a production line unit, differing in their area of use but similar in their function, that is, determining the weight-count relationship of various seeds to derive data on seeds per pound or seeds per gram

The Laboratory Weigh-Count unit is designed to be operated under laboratory conditions where the operator pours a sample of seed into the unit which then proceeds to count a selected number of seeds, for example, 500, into the weigh cell of a precision balance to obtain the weight of those seeds so that the control computer can compute the seeds per pound or per gram.

Multiple replicates may be taken from the sample, there by allowing the computer system to determine various statistical characteristics of the sample such as average, standard deviation, mean, and other calculations that best describe the sample and its variability.

At the completion of testing all seed is automatically returned to the original supply bag which had been placed on the discharge of the unit prior to starting the sample analysis. Data so obtained may be held in a C-Flash memory built into the unit and/or be printed by an optional label printer on a self-adhesive label that may be attached to the sample bag.

The Production Weigh-Count unit is designed to be an integral part of a seed processing line where seeds per pound or per gram data is needed to characterize the material being produced as it flows through the processing line.

A sampler periodically samples the flow stream, diverting seeds to be tested into the weigh-count unit. As in the Laboraory Weigh – Count unit, a specific number of seeds are counted into the balance weigh cell and the control computer calculates the seeds per pound or per gram. The weigh cell contents as well as any remaining seed in the feeder are then emptied into a seed accumulator from which it flows out of the unit and is returned to the stream being analyzed.

The unit is self-cleaning between samples preventing carry over from one sample period to another. All functions of the system including sampling, counting, weighing, calibration, and data computations are carried out by the built-in control unit. Data obtained is transmitted to the processing line computer or placed in the C-Flash memory with time and sample information.
