HJCHEM 50L Pilot Stainless Steel Nutsche Filter Reactor is designed for pilot plants and kilo labs, combining reaction, agitation, solid-liquid filtration, cake washing, reslurry washing, and wet-cake discharge in one enclosed vessel.
The 50L jacketed stainless steel system is suitable for process development, scale-up, and small-batch production.
Vessel material, agitator, filter medium, feeding method, ports, instrumentation, and control configuration can be customized according to the process.
Process functions: Reaction · Agitation · Filtration · Cake Washing · Reslurry Washing · Wet-Cake Discharge
In-vessel cake drying: Not included
What is a Stainless steel Filter Reactor?
A pilot Nutsche filter reactor is typically used between laboratory development and full-scale production. The 50L configuration is suitable for pilot plants and kilo labs, where batch size, agitation, temperature control, filtration, and washing conditions need to be verified before scale-up.
Compared with a simple Nutsche filter, this design adds a jacketed reaction vessel and agitator, allowing reaction or crystallization to be completed in the same vessel before bottom filtration. The stainless steel construction also makes it more suitable for repeated pilot operation and process scale-up.

Reaction, Filtration, Washing& Wet Cake Discharge
HJCHEM pilot Nutsche filter reactor supports the main process steps within one closed system:
- Reaction & Agitation: Materials can be mixed and reacted under controlled agitation and jacket temperature.
- Filtration: After reaction or crystallization, the slurry can be filtered directly through the bottom filter system. Filtration accuracy from 0.1–200 μm.
- Cake Washing: Wash liquid can be introduced for cake washing or reslurry washing when more intensive solid-liquid contact is required.
- Wet Cake Discharge: After filtration and washing, the retained solids are discharged as wet cake, a lifting trolley with a wet-cake collection tray is recommended for easier material handling.
Completing these steps in one vessel reduces intermediate slurry transfer and is particularly useful for pilot-scale process development and kilo-lab production.
