thin Film dryer


The thin-film dryer is a special type of thin-film evaporator. There are two types of thin-film dryers, the vertical and the horizontal dryer.

If these systems reach their limits when it comes to heat-sensitive products, the successful thin-film evaporator principle ensures gentle processes. Based on their wealth of experience and knowledge from separation technology, our experts realize high-performance vertical and horizontal thin-film dryers, which convince both economically and process technically. For individual results, tailored and not available on the market, our technical center provides the ideal R & D environment to cover in-depth tests, etc.


applications of thin-film dryer

The thin-film dryer is used primarily in the chemical, pharmaceutical and food industries.

Dried products like:

  • Chemical products (pre- and intermediates)
  • Sludges (process sludges, industrial sludges and municipal sludges)
  • suspensions
  • pastes
  • moist solids
  • Saline solutions
  • Products of the fatty acid industry, etc.


advantages of thin-film dryer

  • Minimal value product loss
  • Product protection and purity
  • Gentle evaporation through short residence times and permanent product circulation
  • No deposits on the heating surfaces due to mechanical cleaning
  • Reduced maintenance due to sophisticated construction in the bearing and mechanical seal area

functionality of thin-film dryer

The product is distributed continuously over the entire circumference of the heating wall. With the aid of special wiper elements, the wall contact is constantly renewed and the product stream is simultaneously transported on. The rotor blades do not touch the heating jacket, but prevent encrustation or blockage of the heating surface due to massively constructed wiper elements arranged with a defined gap. This wiper design makes it possible to dry liquid feed products down to the powder form. The different units can be used individually or in combination and the operator can thus benefit from the advantages of different evaporator types.
