On conveyor systems in the food processing industry, some powdered and bulk solid materials such as grains, sugar, and creamer are ignition-sensitive in specific concentrations, particularly when exposed to static electricity discharge. Key concerns are conveyor-system connection points such as inlets, outlets, and storage bins. The concentration of dust can become sufficiently high for a deflagration to occur with accidental exposure to an ignition source, such as static electricity, a spark, flame, or even high heat or friction.

So, the characteristics of the material conveyed and the type of conveyor along with its associated component parts and connection points should be considered in the system’s design to avoid a serious risk of dust combustion and explosion. By carefully selecting and integrating the conveyor system and its components, food processors can minimize the risk of dust explosions while safely conveying materials in a hygienic and energy-efficient manner.
