500L Stainless Steel Electric Heating Vacuum Shear Dispersion Reactor for Chemical, Pharmaceutical & Food Mixing

This 500L reactor is built for processes that demand more than standard agitation. It combines vacuum operation with high-shear dispersion in a single stainless steel vessel, making it a practical fit for chemical, pharmaceutical, and food production lines where particle size reduction, emulsification, or homogenization is part of the daily routine.

We fabricate the vessel from 304 or 316L stainless steel, depending on your process media. The inner tank wall thickness is determined by the working pressure and the specific gravity of your materials. For most atmospheric and moderate vacuum applications, a 4-6mm wall is standard. The polished internal surface—typically Ra 0.4 to 0.8 µm—helps with cleaning and prevents product adhesion. External surfaces can be brushed or matte finished, whichever your plant hygiene protocol requires.

The electric heating system uses a thermal oil jacket to distribute heat evenly, avoiding localized hot spots that can degrade heat-sensitive products. Cooling is handled through the same jacket, allowing you to switch from heating to cooling without changing piping. This is useful when your process requires a controlled temperature ramp, not just a fixed setpoint.

The vacuum shear dispersion system is the core of this unit. The high-speed disperser breaks agglomerates and pulls powders into the liquid phase under vacuum, which reduces air entrainment. For applications like coatings, adhesives, or pharmaceutical suspensions, this means a finer, more stable end product. The anchor or scraper agitator, running at a slower speed, keeps the bulk material moving and improves heat transfer near the vessel wall.

Sealing is handled by a mechanical seal rated for vacuum duty. If you are working with solvents or volatile compounds, we can upgrade to a double mechanical seal with a seal liquid reservoir. This is not a standard feature, so specify your solvent type and expected vacuum level when requesting a quote.

Below is the general specification for this size. Final dimensions and motor power will be confirmed based on the viscosity and specific gravity of your formulation.

Frequently asked questions:

Q: Can this reactor handle high-viscosity materials?
Yes, but the motor power and disperser design must be adjusted. For materials above 50,000 cP, we recommend a larger disperser motor or a different agitator configuration. Share your viscosity range when inquiring.

Q: Is the vacuum system included?
The vessel is built for vacuum, but the vacuum pump package is separate. We can quote a compatible pump based on your required vacuum depth and solvent load.

Q: How do I clean the vessel between batches?
For most products, the polished surface and the anchor scraper allow for a CIP (clean-in-place) spray ball. We can add a spray ball and return line as an option.

Before you request a quote, prepare the following details:

• Material composition and concentration
• Batch volume and required working volume
• Operating and maximum temperature
• Working pressure (atmospheric, vacuum, or positive pressure)
• Viscosity and solid content
• Required mixing outcome (emulsion, dispersion, dissolution)
• Cleaning and seal requirements

Send us these parameters, and we will confirm the vessel design, motor sizing, and sealing arrangement. This approach ensures the reactor matches your process rather than the other way around.
