    Larger Capacity Spray Dryer



    The DL410 is a larger capacity spray dryer that can produce fine particles from 40 to 100μm which are considered to be extremely difficult to produce in laboratories.  It is useful for preliminary tests for pilot plant or expensive samples, micro capture spray drying research, substitute for general laboratory drying method, etc.


    • Liquid sample or solution is not required to undergo any pre or post processes such as filtration, separation, or pulverization
    • Use of organic solvents is fully supported with the attachment of GAS410 Inert N₂ Gas Sealed System
    • Small, expensive and/or heat sensitive samples can be dried quickly and efficiently with this easy to operate system
    • Processes samples as small as 0.5g of solid matter
    • Safe for heat-sensitive samples, such as food or medical products
    • No risk of contamination
    • Digital display of inlet/outlet temperature and drying air volume
    • Detachable drying chamber, cyclone and product vessel
    • Fast and easy clean up
    • The hot air inlet and drying chamber cover automatically move up and down, and since the cyclone and product vessel can easily be removed, cleaning and maintenance after experiment is easy
    • Control functions are conveniently arranged on the control panel for various conditions
    • The temperature recorder, air flow meter, pressure gauge and other measurements allow easy control of experiment conditions
    • Universal power supply and multi-lingual touch screen controller
