GLASS LINED AGITATOR & MIXING

Agitating technology is another word for Pfaudler

Mixing is the critical design component of the batch reactor because good mixing is vital to efficient heat transfer and reaction. Pfaudler has a vast array of mixing technologies with many impeller and baffle options to serve every possible mixing application along with sturdy, drives and safe, reliable sealing technologies. Our Cryo-Lock multiple piece agitator assemblies greatly ease the task of installation and maintenance and provide great process flexibility with simple impeller changes.

PROCESS EFFICIENCY

The mixing process in a batch reactor greatly affects product quality and operating cost. Supported by decades of research and development, pilot testing and real-world application, we design high performing, highly efficient and cost effective mixing technologies.

IMPELLER TECHNOLOGIES

Each chemical process is unique and requires a different mixing design. Whether your process is liquid/liquid mixing, solids suspension, high viscosity or gas dispersion we have the solution. We have many impeller technologies including pitched blade, curved blade and vertical blade turbine, turbofoil, gas dispersion turbine, anchor and helical ribbon designs, each performing a different function for a specific process in single flight or multiple flight configurations.

PFAUDLER MIXING DESIGNS / SOLUTIONS

To create the ideal mixer design, our engineers complete in-depth process reviews and use proprietary software to complete mixing calculations and analysis including power input, power number, torque, pumping capacity, shear forces, stress, mixing times and heat transfer efficiency. With decades of research and development to call upon, as well as pilot testing and real-world applications, we have a large data bank of empirical data for mixer design.

A high level of mixing is required for intimate product contact for efficient reaction kinetics and high turbulence. In addition to this, a high flow is necessary for optimum heat transfer, solid suspension and gas dispersion. The goal of all our mixer designs is high performance with efficiency and low operating costs.

Typical mixing applications include:

  • HOMOGENIZATION – MIXING OF SOLUBLE LIQUIDS (FOR NEUTRALIZATION AND EXTRACTION)

  • SOLID SUSPENSION – SUSPENDING SOLIDS IN THE REACTION MASS (COMPLETE OR UNIFORM AS REQUIRED) (FOR CRYSTALLIZATION AND CATALYTIC REACTIONS)

  • GAS DISPERSION – BREAKING OF BUBBLES AND DISTRIBUTION OF GAS (FOR HYDROGENATION AND STRIPPING)

  • EMULSIFICATION – MIXING OF INSOLUBLE LIQUIDS (FOR DISPERSIONS)

  • HEAT TRANSFER – TRANSFER OF HEAT ENERGY INTO THE REACTION MASS

If necessary, we can also complete Computational Fluid Dynamics (CFD) to analyze mixing problems in detail.

This can include calculating the velocities and directions of solid particles for analysis of lifetime abrasion effects or calculation of local pressure around a turbine to see if cavitation is present and if there is potential risk for damages.
