Sanitary 304/316L Stainless Steel Mobile Stirred Reactor with Pneumatic Control

We build this mobile reactor for chemical and biotech processes where batch flexibility and clean operation matter. It is a self-contained unit on casters, so you can move it between workstations or production lines without re-piping. The pneumatic control system handles valve actuation and pressure adjustments, reducing manual intervention in repetitive runs.

The vessel is crafted from 304 or 316L stainless steel, depending on your process media. We use 316L when chloride exposure or acidic conditions are expected; 304 is a solid choice for general aqueous and organic systems. Internal welds are full penetration and ground smooth, then the surface is mechanically polished to a Ra ≤ 0.8 µm finish for sanitary requirements. For more demanding cleaning protocols, we can electro-polish to lower roughness.

Stirring is handled by a top-mounted agitator with a variable-speed drive. We configure the impeller type—anchor, turbine, or helical—based on your viscosity and mixing needs. The shaft seal can be a single or double mechanical seal, with options for flush or barrier fluids when you need to prevent product contamination or vapor leakage.

Heating and cooling are achieved through a jacket around the vessel, sized to match your thermal load. We offer electric heating, steam, or thermal fluid circulation; cooling options include chilled water or glycol. The pneumatic control panel integrates temperature, pressure, and agitation speed readouts, and we can wire it to your existing PLC or DCS if you require remote monitoring.

This reactor suits pilot plants, small-batch production, and R&D labs in pharmaceuticals, fine chemicals, food additives, and cosmetics. A typical use is scale-up trials where you need to test a reaction before committing to a fixed vessel. The mobility lets you share the unit across different suites, and the sanitary design simplifies changeover between products.

Frequently Asked Questions

Q: How do I choose between 304 and 316L?
If your process involves chlorides, acids, or marine environments, 316L is safer. For general organic reactions and clean aqueous media, 304 is cost-effective. Send us your full chemical composition and concentration, and we\’ll recommend the right grade.

Q: Can the reactor handle vacuum operation?
Yes, we can design the vessel and seals for full vacuum down to -0.09 MPa. Specify your required vacuum level and we\’ll adjust the wall thickness and seal selection accordingly.

Q: How do I clean the reactor between batches?
The polished surface and sanitary welds allow CIP (clean-in-place) with spray balls. We can add a spray ball and drain valve for automated cleaning. For SIP, we provide a steam inlet and condensate outlet.

Q: What information do you need for a quote?
We need your process media (components, concentration, pH), batch volume, operating temperature and pressure, desired mixing intensity, and any special requirements like explosion-proof motors or ATEX compliance. With that, we\’ll propose a suitable configuration.

Before you request a quote, take a few minutes to list your actual process conditions. Think about what you\’re mixing—its viscosity, solids content, and corrosiveness. Also note the required heating and cooling rates, and whether you\’ll run under vacuum. The more precise you are, the better we can match the reactor to your production reality.

We are a manufacturer, so you deal directly with the engineering team. We can adjust dimensions, nozzle positions, and control interfaces to fit your existing facility. Send us your process parameters and we\’ll get back with a technical proposal and pricing.
