Achieving gentle mixing with a horizontal rotary drum mixer
Unlike ribbon mixers and other mechanical batch mixers with impellers, a horizontal rotary drum mixer provides gentle gravity flow of the ingredients to achieve a homogeneous blend. After outlining mixing basics and how the horizontal rotary drum mixer is applied and operates, this article covers factors to consider in selecting the unit for your batch application. Related information provides general batch mixer selection tips.
Batch-mixing fragile, friable, or heat-sensitive ingredients requires gently achieving a homogeneous blend without damaging the particles. A horizontal rotary drum mixer is ideal for gentle batch mixing because it has no impellers to grind or smear particles or generate heat during mixing. But before examining the horizontal rotary drum mixer's operation, it will be helpful to look at some mixing basics.
