Our Range of Dairy Agitators by Premix Technologies:
Premix Technologies offers a diverse portfolio of agitator types specifically designed for the dairy sector:
- I. Top-Entry Agitators: Highly versatile, commonly used in milk silos, processing tanks, and blending vessels, with various impeller configurations optimized for different viscosities.
- II. Bottom-Entry Agitators: Ideal for applications requiring complete drainage, critical for maintaining product integrity and for sterile or aseptic processes (e.g., UHT milk), often utilizing magnetic drive technology.
- III. Side-Entry Agitators: Suitable for large volume dairy tanks where top-entry is impractical or for specific blending requirements, often used for maintaining homogeneity.
- IV. Scraped Surface Agitators: For highly viscous products or applications requiring excellent heat transfer, preventing product buildup on vessel walls.
- V. Magnetic Agitators: Providing a hermetically sealed mixing solution, eliminating the need for dynamic seals and significantly reducing contamination risks – perfect for aseptic dairy processes.

CFD Assisted Agitator Engineering Review
Computational Fluid Dynamics (CFD) is used as an engineering support method to understand liquid circulation, velocity distribution, turbulence, vortex tendency and possible dead zones before finalizing agitator configuration. This helps our team match impeller type, RPM, shaft position, baffle arrangement and motor power with the actual process requirement.
For industrial agitators, CFD review is useful for blending, solid suspension, heat transfer, gas dispersion, slurry handling, fermentation and high-viscosity mixing duties. It gives customers a clearer view of how the mixer will perform inside the vessel, especially where tank geometry, viscosity, solids loading or batch quality is critical.
Engineering Points We Review
- Flow pattern, circulation path and tank turnover
- Dead zones near the wall, bottom dish and process nozzles
- Impeller tip speed, shear level and velocity profile
- Baffle requirement to reduce vortex and improve mixing
- Power draw, torque and gearbox loading for reliable operation
- Scale-up behavior from pilot trials to production vessels
Customer Benefits
- Better agitator selection for the real process duty
- Improved mixing uniformity and batch consistency
- Reduced risk of sedimentation, floating layers and unmixed pockets
- More confidence in motor, shaft, impeller and seal selection
- Useful technical support for new tanks and retrofit applications
