De-dusting of process air in drying plants
Flash dryer
Spray and flash dryers belong to the group of convective drying processes in which an appropriate amount of thermal energy is delivered by a stream of air. The suspensions, solutions or fusions to be dried by either spray drying by nozzles or rotating discs, are sprayed and are dried in a direct and counter-current air flow process using hot air. When using the air flow drying process (see Münstermann’s Air Flow Dryers) firm free-flowing materials are dried during the pneumatic conveying in hot air. The dried product is separated in both drying processes by means of a cyclone, a sluice and/or a filter from the stream of air.
For these industrial drying applications we supply high performance air management and de-dusting systems. Depending on the type of dust and the loading up to 150.000m3/hour process or drying air can be cleaned in one filter. Air temperatures of up to 100°C and a relative humidity of over 90% can be processed efficiently and reliably.
Using top quality filter fleece the residual dust content of under 5mg/m3 can be guaranteed. The cleaning of the filters is carried out using a differential pressure controlled pulse jet process.
Our system solutions are low on maintenance, easy to clean and designed for optimal product recovery.
Procedural drying applications:
- Fruit powders
- Coffee and cocoa powders, und tea extracts
- Milk and whey powder
- Starch
