Boston Shearmill

The Boston Shearmill is our ultimate machine for providing high to extreme shear rates and tip speeds for maximum droplet and particle size reduction. It can mill soft particles down to <1 micron, or hard particles down to 1-2 microns, often in just a single pass at high production rates. The Boston Shearmill often replaces colloid mills and homogenizers where submicron processing is not necessary.

Existing installations include tomato paste enhancement and standardization, ketchup and mustard production, salad dressings, mayonnaise, pet foods and treats, soups, sauces, flavor emulsions, pharmaceutical preps, polymers and more. All Boston Shearmills are standard with three sets of shear heads (rotor/stator), and each head has two distinct stages for a total of six work zones.

This increase in residence time between the stages aids in creating tremendous mechanical and hydraulic energy for applying maximum shear forces into the product. And specifically designed for mayonnaise and salad dressing production, the Admix MayoMill™ is built off this innovative technology and balances shear rate and flow to optimize product quality and consistency.
