VetterTec Spray Dryers

VetterTec offers spray dryers based on 30 years of experience and 150 references world wide in the food and chemical industries. The special know-how in the design of the atomizers provides high reliability and a sophisticated solution to give the particle characteristics for the desired application.


Characteristics

The VetterTec spray dryers are designed to dry liquids to powder by means of an atomizer in a high efficient range. This very gentle drying is mainly used to dry heat sensitive products. VetterTec is focusing the brewery, ethanol and chemical industries and is able to build spray dryers from pilot plant size to industrial units.


Function and Principle of Operation

The VetterTec spray dryers offer a high flexibility of design.

Atomisation is provided by centrifugal wheels, pressure nozzles or two-fluid nozzles. This range of systems allows the specific particle size requirements to be met for each application. Direct or indirect heating systems are supplied depending upon the industry standards for the product. Inlet temperatures may range from 100°C for very heat sensitive products to 750°C for some inert chemicals.

Closed circuit and self-inertised dryers are supplied to allow organic solvents to be dried and to meet the environmental specifications.

Different chamber configurations are used along with a range of residence times to provide the desired particle size and moisture content in the finished powder.

Agglomerated products are produced by using integrated fluid beds, fines recycle systems and external fluid beds. These powders are widely used in the food industries.
