The GUNT Plate and Frame Filter Press Trainer demonstrates discontinuous filtration for separating solids from suspensions—commonly used in industries like beverage processing. A diatomite-water suspension is prepared in a tank and kept mixed using a pump to prevent settling. The pump feeds the suspension into individual separating chambers made up of filter frames and plates. Each filter plate is grooved and covered with filter cloth. Filtrate passes through the cloth, travels via grooves into a collecting pipe, and exits into a scaled filtrate tank. The solid forms a growing filter cake at the cloth surface. As the cake thickens, resistance increases until filtration ends when a pressure threshold is met or the chamber is full. Plates and frames are then separated to remove the cake, and reassembled for the next cycle. The press is secured using a spindle to ensure leak-free operation. A manometer displays filtration pressure, and an opacimeter is included for assessing filtrate quality.
