Stainless Steel Reaction Kettle with Agitator Motor for Chemical Mixing

When you\’re running a batch process that involves heating, cooling, and mixing under controlled conditions, the vessel you choose has to hold up under real production stress. We build this reaction kettle for exactly that kind of work — not as a showpiece, but as a workhorse for chemical, pharmaceutical, and food processing lines.

The body is made from 304 or 316L stainless steel, depending on what your process contacts. We weld with full penetration and back-purge argon to keep the inside smooth and free of crevices where product could hang up. The interior surface is mechanically polished to a Ra of 0.4–0.8 µm, which makes cleaning and sterilization straightforward. If you\’re dealing with chlorides or acidic media, we\’ll steer you toward 316L without upselling — it\’s just the honest call.

The agitator is driven by a top-mounted motor with a mechanical seal or magnetic coupling, depending on your pressure and leak-tightness needs. We offer anchor, paddle, turbine, or helical ribbon impellers. The right choice depends on your viscosity and whether you need gentle blending or high shear. We\’ll match the motor power, speed range, and impeller geometry to your batch volume and mixing targets.

Heating and cooling can be handled via a jacket or half-pipe coil, using steam, hot oil, or chilled water. We can also build in a PTFE-lined or glass-lined option if your chemistry demands it, though that changes the cost and lead time. The kettle is rated for full vacuum to moderate pressure — typically up to 10 bar — but we\’ll confirm the exact rating based on your vessel size and nozzle loads.

Where does this reactor actually get used? In resin and adhesive production, where viscosity climbs as the reaction proceeds. In pharmaceutical intermediates, where batch reproducibility and cleanability matter more than speed. In food emulsification, where the scraped-surface agitator keeps heat transfer uniform. We\’ve shipped units to plants making dyes, coatings, and personal care products, and each installation had its own quirks — that\’s why we ask for your process details before quoting.

Frequently Asked Questions

Q: How do I know which stainless steel grade to pick?
If your process involves chlorides, acids, or salt, go with 316L. For neutral or mildly alkaline solutions, 304 is fine and more economical. Tell us the exact chemical composition and concentration, and we\’ll recommend a grade — we don\’t guess.

Q: Can I run vacuum and pressure in the same vessel?
Yes, but the design must account for both external pressure (vacuum) and internal pressure. We\’ll calculate the required wall thickness and reinforcing rings. Be upfront about your operating range.

Q: What about cleaning between batches?
We can add a spray ball or CIP header if you need automated cleaning. For manual cleaning, the smooth polish and rounded corners make it manageable. Just specify your cleaning protocol.

Q: How long does a custom build take?
Typical lead time is 4–8 weeks depending on complexity and current shop load. Rush orders are possible for standard sizes, but we won\’t compromise on welding quality.

Q: Do you provide installation support?
We supply detailed drawings and can arrange on-site supervision if needed. Most customers handle installation with their own crew, but we\’re available for commissioning.

Before you request a quote, gather these details: the exact material you\’ll process, its chemical composition and concentration, batch volume and working volume, maximum and minimum temperatures, pressure (including vacuum), viscosity range, and the mixing outcome you need — like uniform suspension, heat transfer, or emulsion stability. Also note any cleaning or compliance standards (FDA, ATEX, etc.) that apply. With that information, we can recommend the right configuration and give you a realistic price and delivery date.
