Pulse Spray Drying (PSD)

Instant tranformation of liquids and pastes into powders, processsing high-quality products with benefits that make a difference.

HOW IT WORKS

The air is blown inside the combustion chamber of the Pulse Generator (PG) when the rotary valve opens.

HOW IT WORKS

The gas is injected into the combustion chamber in continuous.

HOW IT WORKS

Air and gas are mixed in the combustion chamber and are ignited extremely quickly.

The resulting combustion generates a thermoacoustic wave (pulse) that leaves the combustion chamber through the tail-pipe at very high acceleration.

HOW IT WORKS

The cycle is repeated more than 100 times per second, generating more than 100 pulses per second.

HOW IT WORKS

The liquid or pasty product is injected at low pressure at the end of the tail-pipe through a simple injector.

The pulses atomize the product into thousands of droplets, generating a spray of product going inside the drying chamber. 

 

Benefits

Benefit 1

Strong advantages over traditional drying systems.

Benefit 2

Possibility for drying liquids and pastes with high viscosity and high concentration, impossible for other drying technologies. 

Benefit 3

High final product quality.

Benefit 4

Energy consumption typically 20-30% lower than conventional technologies.

Benefit 5

Important reduction of microbiological contamination.

Benefit 6

Compact design. Smaller equipment size than similar capacity spray dryers.

Benefit 7

Quick, easy and economic retrofits of existing spray drying plants increasing evaporation capacity with low investment.

Benefit 8

Reduced maintenance works and costs. Robust design. No use of rotary atomizers nor high pressure pump + nozzles.

Benefit 9

Easy to operate.

Testing facilities

Available pilot plants designed to develop, test and validate our client's processes, allowing to determine the optimal solution for each project.

Capacities

From pilot size up to several ton/h water evaporation capacity.
