Dust Explosions in the Food Industries

01.Jul.2020

​The ignition temperature of a dust cloud in the air atmosphere and of dust layers in hot environment, have been investigated for several particle sizes of a number of food materials.  Mixtures of fine and coarse dusts of the same material have also been studied.  Measurements for the dust cloud and the dust layer were made in a Godbert- Greenwald Furnace apparatus and in a tube furnace, respectively.  The results obtained indicated that the ignition temperature is dependent on the type of the material and its particle size for the cloud and the layer. An admixture of fine lentil dust of 50% to coarse dust is sufficient to reduce the values of ignition temperature for the dust cloud by 63%.  Value of the ignition temperature for layers of corn starch is lower than that of the other materials studied.
