High-Shear Homogenizing System

This Homogenizer Pump and Mixing Tank Set is a complete inline circulation processing platform that combines a high-shear homogenizer pump with a multifunctional mixing vessel.

Designed for closed-loop operation, it delivers superior emulsification, dispersion, and particle size reduction—far beyond the capabilities of traditional single-tank agitators. Ideal for cosmetics, food, pharmaceuticals, and chemical applications.

How It Works (Closed-Loop Circulation)

Unlike bottom-entry homogenizers, this system uses an external circulation design:

1. Macro-Mixing in Tank: The vessel is equipped with an anchor or frame agitator for bulk mixing, heat transfer, and preventing sedimentation.
2. High-Shear Processing: Product is drawn from the tank bottom into the homogenizer pump. Inside the pump head, a high-speed rotor and precision stator work together to generate intense mechanical and hydraulic shear forces (up to hundreds of thousands of cuts per minute), along with cavitation and impact effects.
3. Recirculation & Refinement: The processed material returns to the tank via a tangential inlet, blending with the bulk batch. Through multiple passes, droplets and solid particles are progressively reduced to micron or even sub-micron sizes.

Key Features & Benefits

· Superior & Reproducible Homogenization: Tight rotor-stator clearance (down to 0.5 mm) and high tip speeds (up to 38+ m/s) ensure consistent batch-to-batch quality, even for high-viscosity creams and suspensions.
· Flexible & Modular Design: The homogenizer pump can be mounted on a mobile cart for easy integration with multiple tanks. Tank options include single-wall, double-wall, or triple-wall configurations (with heating/cooling jackets).
· Easy Cleaning & Maintenance: All product-contact parts are made from SUS304 or SUS316L stainless steel with mirror-polished internal surfaces. No dead corners—fully supports CIP/SIP (Clean-in-Place / Sterilize-in-Place).
· Versatile Operation: Directional valves allow switching between feeding, discharging, recirculation homogenization, and CIP cleaning within a single setup.

 How it Works

The advantages of Silverson’s high shear rotor/stator batch mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine.

  Stage 1

The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead.

 Stage 2

Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.

Stage 3

This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix.

Stage 4

The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimizes aeration caused by the disturbance of the liquid’s surface
