A spray dryer is a machine used for drying utilizing a spray. To achieve evaporation and create a free-flowing dry powder with regulated average particle size, a spray dryer combines a heated gas with an atomized (sprayed) liquid stream within a vessel (drying chamber). ALAQUA is a spray dryer supplier along with other processing equipment suppliers such as the evaporator, crystallizer, solvent recovery systems, etc.
Some of the worldwide problems of the spray drying powder and their solutions are:
Powder Consistency or low-quality powder creating Bulk Density Issue:
The reason for the powder build-up could be dryer configuration, powder formulation and wider spray angle use, and in a lot of cases the design of the nozzle. Scorched particle deposits and product build-up on the chamber compromise the quality of the powder. The solution to this could be a flat cap profile as it provides a lower outer face profile that reduces the build-up.
Another reason could be the wear part alignment. The designs of the traditional nozzles have problems in alignment between orifice and swirl chamber. This decentralization of parts creates problems in the consistent performance of the spray through drying operations. The spray performance can be increased by the concentric clasp technology.
Low Productivity
Another reason could be nozzle bearding, this can also be caused due to dryer configuration, wider spray dryer usage and powder formulation, and occurs mostly due to nozzle design deficiency. These things increase the frequency of clean-up and lead to a production delay. Stopping production in the short run and cleaning could be a big reason for lower productivity. The solution again is the flat cap profile as its design provides a lower outer face profile that reduces bearding. It also means that fewer cleanup dryers shut down, the bearding process slows down providing a longer run of nozzles. For more Information Please visit on Site - https://www.alaquainc.com/
