Squeeze Through Mixing Blade Assembly with Trailing Scrapers

Pat #7,914,200 granted Mar 29, 2011

There are numerous designs for scraped surface agitators. Some are intended to aid in heat transfer and cause flow of thixotropic materials. Others, intended for use with highly viscous materials, are meant to force batch turnover while aiding heat transfer. All share the purpose of heat transfer from scrapers attached to a bar or rod rotating along the periphery of the mixing tank.
