Heavy-duty 4-gallon Double Planetary Mixer features:

  • Two patented High Viscosity stirrer blades which rotate on their own axes while orbiting mix vessel on common axis with slicing motion that pushes product forward and downward
  • Equipped with electromechanical lift to raise/lower vacuum hood
  • 50-psig heating/cooling jacket on mix can
  • Product contact parts constructed from stainless steel type 316, 150-grit finish and electropolished
