Plate & Frame Filter Press | NutriForge – 03
The Plate & Frame Filter Press NutriForge – 03 clarifies intermediate products through discontinuous cake filtration, commonly used in the beverage sector. This Plate & Frame Filter Press features 10 opening separating chambers, a steel suspension tank, and a PMMA filtrate tank with level scale. It includes a centrifugal pump, pressure gauge, and flow control valve for filtration monitoring. An optional portable opacimeter measures solid concentration in the filtrate.
The Plate & Frame Filter Press NutriForge – 03 is employed in the beverage sector to clarify intermediate products. This Plate & Frame Filter Press separates water and diatomite suspension into distinct separating chambers formed by filter frames and filter plates. It collects filtrate through grooved plates and filter cloths while building up a filter cake.
Product Overview
To clarify intermediate products, plate and frame filter presses are employed in the beverage sector.
In a tank, water and diatomite suspension are made (recommended). A pump makes sure the solid doesn’t settle and stays in suspension. The plate and frame filter press’s distinct separating chambers receive the suspension from the pump. One filter frame and two filter plates combine to create a separating chamber. Filter cloths are placed on top of the grooved filter plates. The filtrate travels through the filter cloth and into a collecting pipe through the grooves in the plates. Through the collecting pipe, the filtrate leaves the plate and frame filter press and is collected in the filtrate tank.
The filter cloth is where the solid material is split off, where it grows into a filter cake. The filter cake’s flow resistance rises as it gets thicker. The filtration procedure is completed when the separating chamber is filled or a maximum pressure difference has been attained. The plates and frames of this Plate & Frame Filter Press are separated so the filter cake can be taken out. The plates and frames need to be pressed back together for the subsequent filtration. They are pressed together using a spindle. The push pressures make sure that the suspension is forced through the filter cloth and not leaked from the contact points between the plates and frames.
A valve controls the flow rate through the plate and frame filter press. On a manometer, the pressure that is experienced during filtration is displayed. Scaling exists in the filtrate tank. This implies that the flow rate can be determined using a timer. The solid concentration of the filtrate may be evaluated thanks to an incorporated opacimeter. The tests should be evaluated in a drying chamber.

Construction and Design
The Plate & Frame Filter Press NutriForge – 03 is built for discontinuous cake filtration. A steel tank produces the suspension, holding more than 70L. A centrifugal pump, rated at approximately 5m³/h maximum flow rate and 45m maximum head, delivers the suspension to the press. The press has 10 opening separating chambers, each formed by one filter frame and two filter plates, for filter cake removal. Filter cloths sit on top of grooved filter plates, with filtrate flowing through the cloth and grooves into a collecting pipe. Filtrate is collected in a PMMA tank with a level scale, holding 20L. A valve adjusts the suspension flow rate, and a pressure gauge at the inlet displays filtration pressure, ranged 0 to 7bar. The filter area is approximately 0.5m², with a working pressure of approximately 0.4 to 4bar across 10 stages. Plates and frames are pressed together using a spindle for each filtration cycle.
Software
Software NutriForge – 03 (optional). DAQ software specially designed in National Instrument™, LABVIEW™ environment to measure and calculate the results of the apparatus. The software is optional; a set of electronic sensors is included when the software is used. The software can be run in any Windows™ environment.
