Engineering guide / low shear guacamole mixing
Low-shear mixing for chunky guacamole
Low shear is a system property, not a motor setting. The agitator, vessel, fill level, ingredient addition and discharge all determine whether the pieces survive.
01
Define the particle target first
Agree the largest permitted piece, the target distribution and the retained fraction. Without that specification, “gentle mixing” cannot be evaluated. Use a reference sample and the same measurement method after each process step.
02
Choose the agitator for the product
Anchor, paddle, ribbon or scraped-surface agitators move product differently. A chunky product needs bulk turnover without a high-tip-speed blade. A smooth puree may need more uniform blending. The vessel shape and baffles matter as much as the impeller.
03
Control the fill level
Overfilling can reduce mixing and push product into the headspace; underfilling can draw air into the batch. Establish the minimum and maximum working volumes in a trial and mark them on the vessel.
04
Add ingredients in a deliberate order
Disperse liquids and fine ingredients before fragile pieces where the recipe allows. Add avocado pieces late and mix only as long as needed. Record the actual sequence; a recipe sheet that omits addition order is incomplete.
05
Protect the mix after discharge
The mixer outlet, pump, valve and filler can all damage particles. Use a low-shear transfer, short runs and adequate passages. Compare samples at the mixer, after transfer and in the pack.
