When sourcing a detergent powder mixer, you must prioritize the mixing mechanism and material durability. For detergent production, a Ribbon Blender or Paddle Mixer is typically preferred due to their ability to handle powders with varying bulk densities. Ensure the contact parts are made of SUS304 or SUS316L stainless steel to prevent corrosion from chemical surfactants. Additionally, verify the coefficient of variation (CV), which should be less than 5% to ensure a homogenous blend of active ingredients and fragrances.
