The Feldmeier bottom entering “RapidMixer” is designed to dissolve or disperse solids or semi-solids in water or non-aqueous media quickly and thoroughly. These belt driven mixers feature a heavy-duty impeller which sustains a constant circulation up the vessel walls and down the liquid center to achieve maximum exposure of product to heat transfer surface. Standard sizes range from 25 hp to 100 hp for batches up to 600 gallons. Offset belt driven are standard; direct drives are available as an option. The “RapidMixer” is USDA-MID approved. The RapidMixer agitator may be installed in single shell or insulated & jacketed vessels both cylindrical and square.
