Instant and efficient drying
Lessine’s flash dryers are designed for instant and efficient drying, removing free moisture from products within seconds without altering their properties.
Operating principle
Flash dryers operate by dispersing material into a jet of hot air that rapidly transports it through a drying duct. This process combines a turbulent effect with fast drying, allowing particles to dry within seconds.
Thanks to this high-performance drying system, wet products are instantly transformed into dry powders without further thermal alteration of the product. A loop with a separator can be added to ensure drying by recirculating the still-moist particles.
A industrial paddle mixer is used at the flash dryer inlet to granulate pasty or sludge products before injecting them into the flash dryer.
Applications
The flash dryer is ideal for processing fine granulated products, suspended powders, and solutions in the following sectors:
- Circular economy and recycling
- Minerals and ores
- Fertilizers, chemicals, fine chemicals
- Food and pharmaceuticals
- Metals and precious metals
Advantages
- Ideal for heat-sensitive products
- Instant drying of materials
- Moisture removal in seconds
- Minimal alteration of the material
- Simple drying system with few moving parts
