ABSTRACT:
This invention relates to a system for the prevention of caking or solidification of powdered and granular materials in fire extinguishers and other cylindrical or closed containers. Dry chemical fire extinguishers sometimes fail to function when the material contained in their cylindrical bodies solidifies and cannot be vented through the nozzle of the extinguisher. Fire extinguishers can be rendered more effective and failsafe by way of this invention since, by rapid rotation of a coil or other form or forms imbedded within the material, the material may be fluffed up and caking, solidification, or impactment from settlement may be eliminated thereby. Also, any contained powdered or granular material may be stirred by creating turbulence within the material by rotating a coiled steel form or other forms through the use of a magnetic force induced through the walls of the container.
