The Flash Cooler cools powders and fine granules while transporting it at the same time. In a matter of seconds, the product is cooled and transported pneumatically to a hopper or to a packing line. The Flash Cooler is a very effective solution to combine two process steps.
Hot product enters the flash pipe, where an optional eccentric feeder can break up any lumps to ensure consistent particle size. High-speed cooling air — typically ambient air — picks up the product and disperses it throughout the flash duct.
As the particles travel upward with the cooling air, they cool rapidly — reaching just a few degrees Celsius above ambient temperature within seconds. This fast cooling process preserves the functionality and quality of the product.
Roughly midway through the cooling stage, the product passes through the Ingetecsa Top Bend — a specially designed duct element that further enhances cooling efficiency.
Conveying distances can range from just a few meters to up to 200 meters, both horizontally and vertically, much like a pneumatic transport system.
At the end of the cooling process, a group of cyclones or a baghouse filter separates the fine particles from the air, completing the cooling and collection process efficiently.
Top Bend
In most traditional flash coolers, a simple half-circle bend is used at the top of the flash pipe to reverse the gas flow. These conventional bends serve purely to redirect the flow downward, offering no real contribution to process efficiency. The Ingetecsa Top Bend is different. Our proprietary Top Bend technology is engineered not just to reroute the gas, but to actively enhance system performance. By increasing the gas impulse, our Top Bend measurably boosts thermal efficiency — making your process faster, more consistent, and more energy-efficient.
Advantages
The Ingetecsa Flash Cooler is engineered for simplicity and reliability. The flash pipe itself has no moving parts and no dead zones where particles or bacteria could accumulate — ensuring a hygienic, low-maintenance system. Much like a pneumatic conveying setup, the routing of the flash pipe is highly flexible and can be adapted to virtually any layout.
What sets the Ingetecsa Flash Cooler apart is its seamless process integration, outstanding product handling, and minimal operating and maintenance costs.
We customise every design to match your product characteristics and process requirements. Our tailored feeding system optimises particle dispersion, airflow dynamics, and heat and mass transfer — resulting in superior end-product quality and greater energy efficiency.
Other air cooling technologies
≡ The Fluidised Bed Cooler is ideal for gentle, slow paced cooling of the granule. Also crystallisation processes to the core of the particles are common in a fluid bed. These processes normally require a longer processing time. For the fluidised bed technology, particles should be relatively uniform in dimension.
≡ When the particle size distribution (PSD) is wider or coarser, the Spiral Flash Cooler is likely the better choice. It is a combination of a fluidised bed and a Flash Cooler. The Spiral Flash Cooler is also static technology. It is better suitable for products that consist of a range of smaller and larger particles.
