Pneumatic blending is a fast, clean, and low maintenance approach to achieving homogeneous powder blends using compressed air instead of mechanical agitation
Small amounts of liquid—such as water or oil—can also be injected during blending to wet or lightly coat the powder.
By eliminating internal moving parts, HaF pneumatic blending solutions reduce dead spots, simplify sanitation, and support sealed, dust-controlled operations across a wide range of dry blending and powder wetting applications.
The Pneumatic Blender uses controlled pulses of compressed air to fluidize and circulate dry powders, creating a uniform blend without mechanical agitators. Air is introduced through strategically positioned jets in the blend cone, lifting material upward and allowing surrounding product to flow inward—repeating this cycle until homogeneity is achieved. With no internal moving components, the system minimizes maintenance, improves cleanability, and eliminates dead zones common in traditional mixers.
The Jet Mixer is a pneumatic blending solution designed for dry powder blending with integrated liquid wetting capability. Like a pneumatic blender, it uses controlled pulses of
compressed air to fluidize and circulate powders—eliminating mechanical agitators and internal moving parts. A metered amount of liquid can be injected during the blending process to lightly coat powder particles, supporting wetting, coating, or functional additive incorporation while maintaining a sealed, dust-controlled system.
Jet mixing technology is primarily used for powder blending and is selected when a small percentage of liquid must be evenly distributed across dry material without transitioning to liquid mixing.
Both systems use compressed air and contain no internal moving parts, but they serve different blending objectives.
A Pneumatic Blender is used for blending dry powders and bulk solids where no liquid addition is required or where optional liquid injection is minimal.
A Jet Mixer is used when blending dry powders with controlled liquid wetting or coating. A small percentage of liquid is injected during blending to evenly coat particles, enabling
applications such as oil addition, flavor coating, or functional additive incorporation—without transitioning to liquid mixing.
HaF works with customers to evaluate material characteristics, liquid addition requirements, and process goals to determine the appropriate solution.
No. The Jet Mixer is not a liquid mixer. It is a pneumatic powder blending system that allows a small amount of liquid to be injected for particle coating or wetting. The process remains powder-based and does not involve liquid circulation or tank mixing.
Mechanical blending relies on internal agitators, paddles, or ribbons to physically move material. These components can create dead spots and increase maintenance and sanitation challenges.
Pneumatic blending uses compressed air instead of mechanical motion, eliminating internal moving parts. This results in easier cleaning, reduced maintenance, improved dust control, and efficient blending for suitable materials. Mechanical mixing may still be preferred when specific shear or agitation profiles are required.
Pneumatic blending and jet mixing are best suited for dry, easily fluidizable powders. Fine to moderately sized particles typically respond well to air-based blending, while larger, denser, or irregular particles may not fluidize effectively.
Yes. Pneumatic blending systems—including jet mixers—can be designed with integrated liquid injection nozzles. Liquids are added at low percentages to coat or wet powder particles, supporting applications such as oil addition, flavoring, or functional ingredient incorporation while maintaining a sealed process.
Although compressed air is used for blending, HaF pneumatic blending systems are fully sealed and engineered with controlled air introduction and filtration where required. This helps maintain a clean operating environment and minimizes dusting.
Yes. HaF pneumatic blending systems are custom engineered based on material characteristics, batch size, sanitation requirements, liquid addition needs, and overall production goals. Systems are often integrated into broader material handling or batching solutions.
