What’s new about the spray drying system in a nutshell!

The Mini Spray Dryer S-300 offers you unique features you cannot find in any other spray drying equipment. With this cutting-edge instrument, you can:

    • Automatic system regulation of spray drying parameters, such as spray gas, drying gas and pump speed
    • Automatic system monitoring of outlet temperature and product temperature, especially important for heat-sensitive samples
    • Conductive coating of cyclone to reduce sample from sticking to the walls
    • Stainless-steel spray drying nozzle strengthened with a ruby stone
    • Auto mode for a fully automated spray drying workflow
    • Method programming options to save and repeat runs, process one sample after another automatically
    • Printing of reports in different formats by pushing one button
    • Remote monitoring and control of the spray dryer via an app on any mobile device or computer
    • Effortless system maintenance and cleaning, as cyclone can be easily taken apart
    • Inert Loop S-395: safely spray dry samples with organic solvents where the nitrogen drying gas is circulated, the solvent is collected as condensate and the oxygen level and gas flow in the system are continuously monitored
    • Dehumidifer S-396: provides dry air to enable continuous work with water and organic solvent mixtures with stable spray drying conditions

History of spray drying

The spray drying technique was first described in 1860 with the first spray dryer instrument patented by Samuel Percy in 1872 in the United States. With time, the spray drying method grew in popularity, at first mainly for milk production in the 1920s and during World War II, when there was a need to reduce the weight and volume of food and other materials. In the second half of the 20th century, commercialization of spray dryers increased, as did the number of spray drying applications to include formulations of powdered soaps, detergents, pharmaceuticals, food items, fertilizer, polymer resins, mineral ores, clays and others.

BUCHI has been developing lab-scale spray dryers since 1978, when it introduced the Mini Spray Dryer B-190. The spray drying system was used for applications such as spray drying and micronization, structural changes, englobing and micro-encapsulation, powder coating (agglomeration), prilling (spraycristallization) and to recover synthetic and extraction products. BUCHI followed up with a new version, the Mini Spray Dryer B-191 with an improved control panel, the same year. The company went on to release a Fluid Bed Dryer B-710 in 1982, the most recent Mini Spray Dryer B-290 in 2002 and the Nano Spray Dryer B-90 for smallest sample amounts and maximal product yields in 2017.
