Recommended Mixing Equipment For Pectin

Pectin

The Ross Solids/Liquid Injection Manifold (SLIM) Technology is well proven for fast and complete hydration of pectin powders as well as other kinds of thickening agents. The SLIM is a unique rotor/stator mixer designed to create a powerful vacuum that draws powders sub-surface and injects them directly into a high shear zone where they encounter liquid for the first time.

In conventional mixing systems, pectin powders are slowly added from the top of an agitated liquid batch to minimize agglomeration. In some processes, pectin is blended with other dry ingredients, such as sugar, before being added into liquid. Even then, prolonged mixing is often necessary to ensure complete dissolution. In extreme cases, solids are intentionally overdosed and the undispersed agglomerates are simply filtered out. This keeps cycle time within a reasonable period and ensures a homogenous product, but the additional filtration step with its associated labor and maintenance, along with wastage of raw material, entails significant costs and is hardly an attractive solution.
