500L Stainless Steel Continuous Crystallizer Reactor with Agitator for Food

500L Continuous Crystallizer Reactor – Built for Real Processing Conditions

We manufacture this 500L crystallizer reactor for operations where temperature control and consistent mixing matter more than flashy features. The vessel is constructed from stainless steel, with weld seams fully penetrated and smooth-polished on the product contact side. Internal surface finish is typically Ra ≤ 0.8 μm, but we can adjust that if your process requires a different roughness for cleaning or product release.

The agitator is sized for moderate viscosity slurries and crystal slurries. We use a pitched-blade or anchor impeller depending on your solids content and heat transfer needs. The shaft seal is a mechanical seal, double or single, chosen after reviewing your operating pressure and whether you run vacuum cycles. For food-grade lines, we offer FDA-compliant gaskets and complete drainability with a sloped bottom outlet.

Heating and cooling are handled through a jacketed outer shell. Steam, hot oil, or chilled water can be circulated through the jacket. If you need precise temperature ramps, we can add a control loop with a PT100 sensor and a pneumatic or electric control valve. The reactor is designed for continuous operation, with inlet and outlet ports arranged to maintain steady flow and avoid dead zones where crystals can accumulate.

Material selection is straightforward: 304L for most chemical and food applications, 316L where chloride exposure or higher corrosion resistance is required. We keep mill certificates for every heat used. External surfaces are brushed or painted to your specification. All nozzles are positioned for easy access and cleaning.

This equipment fits industries like edible oil processing, pharmaceutical intermediate crystallization, fine chemical synthesis, and specialty food ingredient production. Typical uses include cooling crystallization, reactive crystallization, and pH-controlled precipitation. If you handle abrasive solids, we can specify a hardened shaft sleeve or a higher-grade impeller material.

Technical Specifications

FAQ – What Buyers Usually Ask

Q: Can this reactor handle vacuum operation?
Yes, if you specify vacuum service, we use a stronger shell and a suitable seal. Let us know your required vacuum level.

Q: How do I clean the vessel between batches?
We can add CIP spray balls and a flush ring. The polished interior and sloped bottom make manual cleaning straightforward too.

Q: What if my process needs a different agitator speed?
We offer variable speed drives and gear reducers. Tell us your viscosity and desired tip speed.

Q: Can you provide documentation for food contact?
Yes, we supply material certificates and can provide FDA or EU conformity statements for the gaskets and surface finish.

Getting the Right Configuration

Before you request a quote, gather these details: the exact chemical composition and concentration of your feed, your batch volume and working volume, operating and design temperatures, pressure (atmospheric, positive, or vacuum), viscosity and solids content, heating/cooling requirements, and the mixing outcome you expect. Also note any cleaning or compliance standards you must meet. With that information, our engineers can recommend the correct vessel thickness, agitator design, seal type, and jacket arrangement.
