Drying unit for the production of pure anionic surfactants in dry form and
different physical shapes (flakes, needles, powder and granules) in accordance
with the most stringent quality standards.
The unit is based on the use of wiped film evaporators specifically designed and
developed for this application.
Major advantages of the Desmet Ballestra drying technology are:
Very high heat transfer coefficient that ensures the achievement of the
desired product dryness in a very short time so to minimize the time of
performance of the product at high temperature and, therefore the risk of
Very accurate control of the wall temperature to prevent local overheating
of the surfactant.
Mechanical design with wiping blades that ensure a constant and uniform flow
of the product through the evaporator preventing accumulation of product
inside the machine and, therefore, product degradation due to overheating.
