Abstract

The maple syrup filtering process includes generating pressure with a variable power output pump to generate a flow of maple syrup in a filterpress apparatus from an inlet to an outlet. The maple syrup is filtered with a filtering medium as it flows between the filterpress inlet and outlet, to generate filtered maple syrup. Fluid pressure of the maple syrup is monitored with a pressure sensor located upstream of the filtering medium. The fluid pressure might fluctuate as a result of a composition of the unfiltered maple syrup or the level of clogging of the filtering medium. A variable power output of the pump is automatically controlled with a controller responsive to fluctuations in fluid pressure monitored with the pressure sensor to achieve a target pressure measured at the pressure sensor. The filterpress apparatus can include a series of filters through which the maple syrup is filtered.
