Spray drying system for heat sensitive products
In industries like food and chemicals, transforming liquid solutions into dry powders without compromising the quality is critical. This is especially challenging when dealing with heat-sensitive materials that require gentle, efficient drying methods.
Efficiently dry liquids into powder
The VetterTec spray drying system is a specialized technology designed for drying liquids into powders using high-efficiency atomizers. This system is particularly effective for heat-sensitive products, as the liquid is atomized into fine droplets and introduced into a hot air stream, causing rapid evaporation without damaging the material. The dried powder is then separated from the air using a cyclone and/or filtering systems. Features like fluid beds and coolers can be integrated to further condition the finished powder for packaging. VetterTec offers a range of atomizers—centrifugal wheels, rotary atomizers, pressure nozzles, and twin-fluid nozzles—allowing customization to meet specific particle size and shape requirements. Direct or indirect heating systems are available, with inlet temperatures ranging from 100°C to 750°C, making the system suitable for various applications, including those requiring organic solvent drying and adherence to environmental standards. Industries served include food, starch, and chemical sectors, with applications such as whey protein concentrates, polymers, pigments, and vegetable proteins.
