Vertical Stainless Steel Reactor Tank with Agitator for Liquid Processing

We build vertical stainless steel reactor tanks for chemical, pharmaceutical, food, and cosmetic processes that demand reliable mixing and precise temperature control. This vessel is designed for batch operations where the agitator must handle moderate viscosities, suspensions, or emulsions without dead zones. The vertical configuration saves floor space and simplifies bottom discharge, making it a practical choice for many production lines.

The tank is fabricated from 304 or 316L stainless steel, depending on your process media. For corrosive or high-purity applications, 316L with low carbon content is the standard recommendation. We use full-penetration welds, followed by grinding and electropolishing on all wetted surfaces. Interior surface finish can be specified from 0.4 to 0.8 µm Ra, which helps reduce product buildup and eases cleaning between batches. The agitator is a top-mounted, direct-drive or gear-reduced unit with a choice of impeller types—anchor, turbine, or pitched-blade—matched to your mixing requirements. Shaft sealing is handled by a single or double mechanical seal, with options for flushed or barrier fluid systems when processing volatile or hazardous materials.

Heating and cooling are achieved through a jacketed vessel, using either a dimple jacket or a half-pipe coil, depending on the required heat transfer coefficient and working pressure. The jacket can be designed for steam, hot oil, or chilled water. The reactor is rated for full vacuum or up to 10 bar internal pressure, and the design temperature range is typically -20°C to 200°C. Custom pressure and temperature ratings are available, but we need your exact process parameters to avoid over- or under-specifying the vessel.

Typical applications include resin polymerization, dye intermediate mixing, fermentation broth preparation, liquid detergent blending, and cosmetic lotion manufacturing. The tank can be fitted with additional nozzles for sensors, sampling, or sight glasses. We also offer options like a spray ball for CIP, a bottom flush valve, and a variable frequency drive for the agitator motor.

Before you request a quote, gather the following details: the chemical composition and concentration of your materials, the batch and working volume, the operating and design temperature, the pressure conditions (atmospheric, pressurized, or vacuum), the viscosity and solids content, whether you need heating/cooling, and the desired mixing intensity. Also note any cleaning or sanitary requirements. With that information, our engineers can specify the correct vessel geometry, agitator type, seal configuration, and jacket design.

FAQ

Q: Can I use this tank for high-viscosity pastes?
Yes, but the agitator and motor must be sized accordingly. Anchor or helical ribbon impellers are better for pastes, and we will adjust the motor power and gear ratio.

Q: What is the lead time for a customized reactor?
Typical lead time is 30–45 days after drawing approval, depending on the complexity and your order volume.

Q: Do you provide documentation for pressure vessel compliance?
We can provide material certificates, weld maps, and hydrostatic test reports. For ASME or PED certification, please specify your requirement at the inquiry stage.
