20-Inch Filter Presses
20’’ filter presses crafted by H2O Innovation are composed of lightweight aluminum plates (3 or 6 sets). Syrup inlet and outlet are located on the rear plate which is fixed to the frame of the filter press.
A filter press serves to remove suspended solids and sugar sand from the syrup after it comes off the evaporator. The syrup filter press works hot, at an approximative temperature of 180°F.
Paper filters must be used with filter aid (diatomite) to filter the syrup. A food grade product, diatomaceous earth consists of perforated and striated micro-shell fossils, having a considerable filtering power.
When assembling the press, alternate hollow and waffle plates. Hollow plates allow the syrup to enter the press and they hold the filter aid and residue. Waffle plates provide backing for the filter papers and allow filtered syrup to exit the press.
Filtration capacity will vary during the season, but also with the fouling level (filter aid and sugarsand). The press and its filters must be cleaned frequently.
