    Food Processing - Dust Fires

    Good morning and Happy Halloween!
    Gonna try to make this candy-centric. lol

    In the past, sugar/candy factories have had problems with dust fires.
    While I know that food processing industries use dust collectors/air filters to keep products safe and the air cleaner, does anyone have any insights to dust collectors for the food industry?

    Grain mills are also prone to explosions. Workers have to wear spark proof soles, take special precautions when working metal to metal....

    NFPA 8.3.3.3.6* The air-material separator (AMS) selected for the system shall be designed to allow for the characteristics of the combustible dust being separated from the air or gas flow.

    Equipment that emits dust should have suction vent connections and/or suction hoods attached. These connect to a manifold, which then connects to a separator (cyclone and/ or baghouse dust filter). With a baghouse filter, efficiencies could exceed 99% depending on the type of filter media and dust characteristics. Dust characteristics must be carefully considered during filter selection and system design. Filter bags and “dust cake” on the surface of media act to separate particles from incoming dirty airstream, resulting in clean air exiting the baghouse to the atmosphere.

    Thanks for the article Juan! You're right. I forgot about grain mills as well.
    What is your opinion on cartridge filters? Do you think bag filters are more efficient?

    Both have a place. Bags are less costly to maintain as you generally can "shake them out" where other media has to be replaced.

    Also, for chuckles, google coal dust explosions.. World is unexpectedly dangerous.
