    1. Carbohydrates contain sugar, starch, hydrogen and oxygen – so they make a good fuel source in the right circumstances. When flour particles have a very large surface area and when suspended in air, in the right mix,they have a large supply of yet more oxygen.
    1. Drum or bag – a mechanism that requires replacement of the drum or bag that collects the matter.
    2. The air to cloth ratio is the amount of air that passes through a square foot of the filter. The lower the ratio, the higher quality of the filtration system's efficiency.
    3. Though a fan or blower may have a simple design, when installed in a dust collection system, several factors have to be considered. First of those factors is the volume of air that needs to be moved. This is measured in cubic feet per minute (CFM). The next consideration is the static pressure throughout the whole system. Other variables are the temperature, substances in the air, and the level of moisture.
    4. Dust collection systems have ductwork to draw in the air, an air purifier, and receptable.

      I don't notice this on COG dust collection system.

    1. According to some reports, food processing is the largest category for combustible dust explosions in manufacturing, accounting for almost 25 percent of incidents.

      I should ask about this in our interview.

    1. properly sized and manifolded to maintain a consistent minimum air velocity required to keep the dust in suspension for conveyance to the collection device.

      Didn't thought about this. I should take a look at the ducting from the ribbon mixer to the tanks collecting the dusts.

    2. Dust collection systems work on the basic formula of capture, convey and collect.

      I need to see how this system works in unison.

    3. It can be as simple as a basic pass-through filter, a cyclonic separator, or an impingement baffle.

      I remember Carlo mention an inertial separator last meeting. It his the same thing? If so, do they use this for food dusts as well?

    1. The places migrants left behind never fully recovered. Eighty years later, Dust Bowl towns still have slower economic growth and lower per capita income than the rest of the country. Dust Bowl survivors and their children are less likely to go to college and more likely to live in poverty. Climatic change made them poor, and it has kept them poor ever since.

      Intergenerational social problems here; we should be able to learn from the past and not repeat our mistakes.
