Blending. Dispersing. Emulsifying. The Tri-Mix™ Turbo-Shear™ does it all – and does it with authority. It’s the perfect combination of the traditional Lee double-motion scraped-surface agitation system and the homogenizing prowess of the Tri-Mix™ Turbo-Shear™ mixing head. That means mass blending, powerful performance, and an impressive variety of mixing applications.

How does it work?

The Tri-Mix™ Turbo-Shear™ utilizes mechanical and hydraulic shearing to dissolve powders, blend miscible and non-miscible solutions, prepare lotions and creams, and disperse pigments. A center shaft, which can be run alone or with a double-motion agitator, operates at speeds up to 3,450 RPM. The scraped-surface, double-motion agitator is used to efficiently pull product from the vessel walls during each blending revolution. The scraped-surface agitator portion operates at speeds up to 50 RPM.

Here’s how the Tri-Mix™ Turbo-Shear™ can help achieve your operational goals:

  •  Product viscosities up to 2,000,000 CPS on primary double-motion means you get the product right, every time.
  • Available from as small as 10-quart research models to as large as 1,500-gallon production vessels.
  • High ratio of hydraulic to mechanical shear means less heat, which improves product consistency and increases overall safety (when processing temperature-sensitive products).
  • Sanitary design means you pass government regulations with ease and save valuable cleanup time.
  • High-velocity axial and radial product flow means production will never get clogged up or slowed down.
  • Continuous high or low flow mixing head means you get the power you need when you need it most.
  • Unique double-motion agitator offset frame means uniform scraping action and continuous product flow.
  • Custom designs mean you get custom results, especially in difficult applications.
  • Batch-to-batch uniformity means your customers can count on your product.
  • Product scale-up means we easily grow with your operation.
  • Our Process Guarantee, based on free testing in our 25-gallon lab Tri-Mix™ Turbo-Shear™, means you have peace of mind.

Particle Size Reduction

In a particle size reduction test, we used a 25-gallon style "D12T" Lee pressure kettle with Tri-Mix™ Turbo-Shear™ agitator. The preparation by approximate weights consisted of: epoxy resin (23%), emulsified in water (29.54%) with Cellosize thickener (.20%), and surfactant (.30%). Here are the results:

We started with double-motion scrapedsurface agitator at 30 RPM.

  • After five minutes, particle size was 55 microns.
  • After 60 minutes, particles were reduced to 30 microns.

Then we used the 3,450 RPM Turbo-Shear™ with a standard head configuration.

  • After an additional 40 minutes, particle size was 5 to 7 microns.

Next we added Cellosize thickener (1.04%), flint (20.48%), and pyrophyllite (25.43%). The double-motion and Turbo-Shear™ agitators were run simultaneously for one hour.

  • Final particle size was 2 microns.
  • Final product viscosity was 40,000 CPS.

Vacuum Pan Options & Accessories

Our vacuum pans are often purchased as part of a larger system. For example, a typical total jam and jelly system would include premix kettles, a vacuum pan with vacuum precondenser, vapor piping and often a final standardization vessel. All of the equipment is sized, designed, and supplied by Lee Industries to fit your specific processing requirements. Regardless of whether you’re in need of a vacuum pan or a system, you have the opportunity to choose from several accessories.

Internal Booster Coil

  • • Sanitary stainless steel booster coil added to vacuum pan
  • Provides additional heat transfer area for increased evaporation
