When Durkee, the big manufacturer of seasoning salts, bought a 30 cu. ft. capacity |»-k twin shell blender, Tech nical Director Stewart Woodruff knew in advance it was the "just right" blender for the job. He knew because he had blended their "difficult" ingredients perfectly in a 4-quart |»-U blender in their lab— and results in (>4t lab models can be scaled up exactly to large production runs. Shells on lab models come in trans parent Lucite or stainless steel, in capacities from one pint to 8 quarts. Production models then range up to 1000 cu. ft. capacity. Each retains the twin-shell's unique 5-way blending action. To find out how you, too, can "pre test" a p-k twin-shell blender in your plant, lab or mill, write today.
