n modern chemical processing, dyes, and metallurgical refining, separating solid suspensions from liquid carrier fluids is a critical operational bottleneck. Traditional filter presses require extensive manual labor and suffer from high cake moisture retention. The Automatic Vertical Tower Filter (AVTF™) by Abhigyan Engineers solves this via a vertically stacked chamber design coupled with advanced PLC-driven automation.
The filtration cycle begins with Plate Closing. High-power hydraulic cylinders squeeze the stack together under multiple tons of force, creating airtight, sealed chambers. Slurry is then pumped into these chambers under pressure. The liquid carrier passes through the synthetic filter cloth, leaving behind a uniform cake layer on top of the cloth.
What sets the AVTF™ apart is the Diaphragm Squeezing phase. Highly pressurized water or compressed air (up to 16 Bar) is pumped behind flexible diaphragms built into each plate. This mechanically compresses the cake, squeezing out interstitial moisture that gravity or feed pump pressure alone cannot reach. By doing so, cake dryness is maximized before discharge.
Next, Cake Washing and Air Blowing cycles occur. Wash water is forced through the cake to remove soluble chemical impurities, followed by high-pressure air that sweeps out remaining moisture. Finally, the hydraulic cylinders retract to open the chambers, and the continuous loop filter cloth indexes forward, automatically discharging the dried cake. The cloth then passes through a spray-washing manifold to clean both sides before the next cycle begins.
By achieving cake dryness levels up to 35% higher than conventional presses, chemical plants using AVTF™ see a proportional drop in their thermal drying oven utility bills. It is a seamless, zero-labor solution that streamlines throughput and reduces total cost of ownership.
