Lindor introduces the ‘Gentle Dryer’ at the ACHEMA

Monday 18 June 2012

Maximal heat transfer for precious and sensitive products

Lindor, known for its gentle touch mixers for Food and Fine Chemicals, is about to introduce its latest development at the upcoming global chemical exhibition ACHEMA in Frankfurt. The ‘Gentle Dryer’ is a machine for impregnating, heating, drying and cooling of powders, granulate and natural products. The design of the machine is based on the Lindor rotary drum mixer. The drum and scoops have a double wall and the machine allows for a hot airstream through the flowing product and the rotating drum. The concept has been registered for a global patent.

Both the drum and the scoops can be heated with saturated steam of up to 8 barg (temperature: 172°C). Condensation of steam in the double jacket of drum and scoops, right at the point where the product requires heating, provides a maximum of heat transfer to the product.

For air drying the machine is equipped with special features to allow a large airflow through the flowing product and rotating drum. Both media, steam and air, can be applied at the same time to optimize heating, drying and cooling. The machine is also equipped with liquid injection nozzles.

To have this drying concept available to test, Lindor has built a test machine with a net product volume of 100 – 1000 litres. This test machine is available for testing from July 1 2012, at the Lindor premises in Dordrecht, the Netherlands (near Rotterdam) or on location. Several companies have already made reservations.

Products for which this concept may prove to be interesting are:
  • Ceramic products
  • Specialty plastics
  • Metal salts
  • Cereals
  • Etc.
Lindor offers with its range of mixing machines the possibility to realise pure processes without ‘side-effects’. With its innovative ‘Gentle Dryer’ another range of possibilities is added.
