Nutsche Filter
Nutsche Filter
A Nutsche filter is an enclosed vessel with a perforated filter plate on which the solid cake collects as the process liquid is drawn through under vacuum or pressure. Mechotech engineers and manufactures the Nutsche Filter as turnkey process equipment for pharmaceutical, nutraceutical, food and botanical processing lines that need straightforward, enclosed solid-liquid separation. Each unit is configured to the client’s feed and target output, then fabricated, installed and commissioned by Mechotech as a single accountable scope.
The Nutsche Filter is built in SS 316L (or a process-appropriate grade) around a vessel with a perforated filter plate, with electropolished product-contact surfaces and integrated instrumentation so it can be cleaned in place between batches and operated under PLC-based control. The filtrate is collected in a filtrate receiver. Filtration area, vessel size, the choice between vacuum and pressure, cake washing and discharge arrangements are configured to the client’s requirement and confirmed during process design and pilot validation; no fixed figures are quoted on this page.

Plant Capacities
| Scale | Typical Duty | Configuration |
|---|---|---|
| Pilot | Process validation and small-batch solid-liquid separation | Small Nutsche vessel with a filtrate receiver |
| Production | Plant-scale batch filtration | Filter plate area and vessel size configured to the feed and the cake volume |
| Large commercial | Larger batch volumes | Larger vessel and ancillaries, with modular expansion |
Filtration area, vessel size, vacuum or pressure duty and discharge arrangement are configured to the feed and batch size; a pilot trial on the actual slurry is recommended before scaling.
Manufacturing Process
Slurry Charging
The slurry or process liquid containing the solids is charged into the filter vessel.
Filtration
Vacuum or pressure draws the liquid through the filter medium on the perforated plate; the solids are retained and form a cake.
Filtrate Collection
The filtrate passes to the filtrate receiver.
Cake Washing (where required)
Where the process needs it, the cake is washed on the plate to displace remaining liquor.
Cake Discharge
The retained solids are discharged from the vessel for the next stage.
Clean-in-Place
The vessel is cleaned in place between batches.
