ABSTRACT:
A 55 gallon drum is provided with a static mixer that enables internal mixing of product during barrel rotation. Before fastening of at least one of the respective lids, a circular elastic ring insert is place within the barrel. This circular plastic ring insert has a diameter exceeding that of the barrel, has two external protuberances for keying to the cylindrical inside of the barrel at internal ribs, and is cut across the ring so as to interrupt the otherwise endless dimension of the ring. Upon insertion to the barrel, the ring is opened at the cut and disposed in an auger like helix along the inside cylindrical wall of the drum. The two protuberances are keyed to the drum interior of the internal ribs to effectively fasten by friction its helical auger like path on the cylindrical inside wall of the drum. Thereafter, the drum is closed and filled with product. Upon drum rotation, relative motion between the contained product and helical auger like static mixer occurs. Product is moved vertically with respect to the drum side walls towards one end of the drum. Product movement continues to the end of the drum with return product flow to the opposite drum end along the axial dimension. When cooling spraying accompanies such rotation, rapid cooling of the entire drum contents results.
