Fristam PM – Powder Mixer
Bespoke Powder Mixing units – Rapid induction of powder into liquid to create a fully homogenous blend.
What is the Fristam PM Powder Mixer?
A Fristam PM Mixer is a universal hygienic mixing and blending system designed for controlled blending, dissolving, re-circulating and homogenizing ingredients to create consistent product quality and structure.
The Fristam PM mixer operates using a precision rotor–stator mixing principle, ensuring rapid ingredient incorporation and uniform distribution. This delivers reliable homogeneity, stable flow behavior and repeatable process results across a wide range of hygienic applications.
Engineered for food, beverage, and pharmaceutical production, the PM mixer is fully CIP-capable and integrates easily into closed processing systems. Its compact, robust design supports efficient cleaning, reduced downtime, and dependable operation in demanding hygienic environments.
Suitable for applications ranging from simple blending and rework to ingredient dissolution and product circulation, the Fristam PM provides manufacturers with a flexible, process-reliable solution for modern hygienic mixing requirements.

How The Fristam Powder Mixer works:
- Powder is tipped into a hopper, which is mounted onto a waist height skid.
- A Fristam Self Priming Liquid Ring Pump pulls liquid into the system, while powder is drawn from the hopper into the liquid stream directly below. This creates a pre-mixture of powdered ingredients and liquid, which is immediately transferred towards the Fristam Shear Blender.
- The Fristam Shear Blender uses a rotor-stator system with very tight shearing clearances to efficiently blend, emulsify, disperse, dissolve multiphase products, and to reduce particle and droplet sizes. The result is a fully homogeneous mix of powder and liquid.
- The system can be used in batch production or in inline processes.
- For cleaning, the unit can be fully integrated in CIP and SIP cycles.

Key Features of the PM Powder Mixer
Vacuum-Assisted Powder Induction
Powder is tipped in a hopper, and a vacuum created by the self-priming liquid ring pump below pulls it into the liquid stream, creating a rapid and controlled powder draw while ensuring fast wetting and reduced air entrainment.
High-Shear Rotor–Stator Mixing System
Delivers consistent dispersion and agglomerate breakdown, improving batch repeatability and final product uniformity.
Wide Application and Process Flexibility
Handles a broad range of powders, flow rates and liquid viscosities across food, beverage, pharmaceutical and chemical processing applications.
Inline Mixing Configuration
Supports continuous processing and integration into existing production lines, reducing tank residence time and manual intervention.
Robust Hygienic Stainless Steel Construction
Manufactured from high-grade stainless steel to provide corrosion resistance, mechanical durability and long operational service life.
Hygienic, Sanitary Design
Engineered to meet modern hygienic processing standards, making the system suitable for demanding clean-production environments.
CIP-Compatible Design
Fully Clean-in-Place capable with optimized internal flow geometry, enabling efficient cleaning without disassembly and minimizing production downtime.
Optional extras:
Big bag adapters, CO2 connectors for the hopper, CIP lids, customized hopper shapes to assist powder induction and prevent bridging, adapters for automated feeding.
