A cheese shredding apparatus has a table top with a rolling platform that uses 2 pairs of beveled wheels. Preferred embodiments are directed to process monitoring andor process control for unit operations involving endpoint determination of a distillation, for example, as applied to a liquid-component-switching operation, a liquid-liquid separation operation, a solute concentration operation, a dispersed-phase concentration operation, among others. The first plurality of channels is offset from the second plurality of channels. The support structure of the apparatus may also include an adaptor section for fitting to a receiver of a hitch of a vehicle. A filter coefficient generator responds to the tuning parameter by providing each of the M notch filters with the corresponding tuning coefficient.
