Description

VetterTec offers spray dryers based on 40 years of experience and 180 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. From pilot plants to industrial units: VetterTec provides a full range of spray drying units and services.

PRINCIPLE OF OPERATION

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.

The atomizer forms the liquid into small droplets before spraying them into a hot air stream, where the major part of the water evaporates in a few seconds. At the end, the dried powder will be separated from the air by a cyclone and/or a filter system. Downstream the dryer can be equipped with fluid beds, coolers and agglomerators, to further condition the powder prior to the packaging unit.

CHARACTERISTICS

The VetterTec spray dryers are individually designed to meet the specific requirements of our customers and offer a high flexibility of design.

Atomization can be provided by centrifugal wheels, rotary atomizers, pressure nozzles or twin-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-inertized 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.

FIELDS OF APPLICATION

Spray dryers are used for various products, especially if there are high hygienical demands at the final product (as in the food industry) or if special particle properties should be met. Since it is a very gentle drying method, it is also used preferably to dry heat sensitive products.

VetterTec Spray Dryers are employed for a wide range of applications. To achieve an optimal operating behavior, each VetterTec dryer is customized. The complete equipment (e.g. the atomization system) is carefully selected and adjusted to an optimum. With internal fluid bed, external fluid bed, rotary atomizers, high pressure nozzles, twin-fluid nozzles and homogenizer, the spray dryer can be adapted to customers’ needs.

VetterTec’s experienced team of spray drying experts is always dedicated to developing the best solution for the specific requirements, as e.g. dust-free powder, agglomerated powder etc.

With the deep know-how in particle engineering, our customers are always getting particles of the desired shape, size and density.

According to requirements, it may be useful to make CFD flow simulations at first, or to run drying tests with our fully equipped pilot plant in Germany.

VetterTec is focusing the food, starch, brewery and chemical industries
