Advantages and capabilities of the Nutsche Filter Dryer include:
Solids filtering, washing, reslurrying, and drying can all be done in a single vessel
Minimal operator/environmental exposure to the materials
Faster filtering possible via pressurizing liquid out than sucking it out via vacuum
Ability to dry solids via vacuum and optional heating
Pope Nutsches are available in a wide range of scale in volumes from 0.2 through 1000 liters. The popular Pope Benchtop Nutsche Filter is often used in small scale production and for scale-up studies in research and development in many industries. These are available in 6-inch diameter, with a choice of 3, 4, or 5 liter volumes.
All Nutsches are pre-fitted and tested with components including valves, sight glasses, pressure relief, spray assembly for cake washing or CIP, pressure/vacuum gauge, plus other optional items for special applications. Most Nutsches are fitted with heating/cooling jackets but can be ordered without, or with electric heating.
Nutsche offers an optional raising/lowering cake agitator to break up lumps for drying efficiency, although some applications call for conventional mixers or none.
