CPM
Conical Paddle Mixer
The CPM conical paddle mixer is a multi-purpose batch mixer designed for mixing, drying and reaction processes with maximum efficiency and minimal product distortion. Its gently rotating paddle rotor generates a three-dimensional mixing pattern ensuring fast, homogeneous results — even with fragile or heat-sensitive materials. The CPM allows full discharge, precise temperature control and excellent product handling.
Key Benefits
- Gentle, low-shear mixing of fragile or segregative powders
- Suitable for mixing, drying and reaction processes
- Accurate temperature control with jacketed vessel and cover
- High mixing accuracy and short batch times
- Fast and complete discharge through the bottom valve
- Compact, energy-efficient, heavy-duty design
- Easy to clean; hygienic construction
- Available from 50 to >15,000 L
Principle of Operation
The CPM Conical Paddle Mixer features a conical vessel with a central paddle rotor that rotates at tip speeds of 1–10 m/s, generating a gentle combination of vertical, axial and radial movement. The paddles lift the product upward along the wall and guide it towards the centre, where gravity draws it back down — maintaining continuous motion even at low speeds.
This controlled, convective movement ensures uniform distribution of all components while preventing product degradation. The mixer’s jacketed wall enables precise heating, cooling or drying, and its open, obstruction-free interior ensures optimal hygiene and minimal product retention.
Thanks to its bottom discharge valve, the CPM achieves full product emptying, reduces manual cleaning, and minimises the risk of cross-contamination between batches. The design eliminates dead zones and allows excellent process reproducibility — ideal for demanding applications such as instant products, powder–liquid blending, or low-temperature drying under vacuum.
Process Flexibility
The Conical Paddle Mixer is suitable for a wide range of process applications, including:
- Mixing of fragile powders and ‘instant’ agglomerates
- Mixing of powders with liquids
- Sterilisation and pasteurisation of product batches
- High-temperature processing of powders and liquids
- (Vacuum) drying at low temperature with liquid recovery

FAQ – Conical Paddle Mixer
What is a Conical Paddle Mixer?
How does the Conical Paddle Mixer work?
The Conical Paddle Mixer (CPM) is a multi-purpose batch mixer for powders, pastes and liquids. It combines gentle handling with efficient mixing, drying and reaction capabilities, ensuring homogeneous results with minimal product distortion and short batch times.
What materials can be processed in the CPM?
The CPM can process a wide range of powders, granules, pastes and liquids, including food ingredients, chemicals, pharmaceuticals and minerals. It is particularly suited for fragile or heat-sensitive materials, as well as vacuum drying or pasteurisation processes.
What are the main advantages of the CPM?
The mixer offers excellent temperature control, energy efficiency, and fast, full discharge. Its compact, hygienic design minimises product hold-up, reduces cleaning time and improves process yield. It can also be used for sterilisation, vacuum drying and reaction mixing.
What sizes and scale-up options are available?
The Conical Paddle Mixer is available in volumes from 50 to over 15,000 litres, with custom-engineered solutions for larger capacities. Hosokawa Micron provides pilot testing and process scale-up services to validate performance before full-scale implementation.
Can the CPM be customised for specific applications?
Yes. Options include vacuum or pressure operation, heating/cooling jackets, special seals, and liquid injection systems. Custom configurations can integrate into complete mixing, drying or sterilisation systems for optimised process performance.
