 PATTERSON Industries
Canada "The
Process Equipment People" custom designs, engineers and manufactures Sigma Blade
Kneading machines for many different industries and service requirements.The
PATTERSON Kneadermaster® is a uniquely designed mixer which provides economical
batch mixing of materials having high viscosities and requiring high shear mixing action
to achieve the desired product consistency.
PATTERSON Kneadermaster® Batch Mixers may be engineered and built in both TILTING and
NON-TILTING Styles for working capacities ranging from 5 USG (19 l) up to 2000 USG (7570
l). Special research and development laboratory scale units have been built as small as
1USG (3.78 l).
Design Features:
 The Sigma
Blade Mixers are precision built. All bearings are of anti-friction type, gearing wide
face precision cut, and all vital gearing is straddle mounted between two bearings. Both
bearings and gearing run in sealed oil tight housings with visible oil level gauges.
Trough, trough ends, and mixing blades may be arranged for rapid controlled heating or
cooling depending upon process demands.
Cored blades assure maximum efficiency in the heating or cooling of materials being
mixed. The Kneadermaster® can be jacketed to further assure temperature control and
uniformity. The heat transfer areas in the mixer are designed so that the material being
processed is constantly exposed to surfaces of controlled temperature.
PATTERSON Kneadermaster® Batch Mixers feature totally enclosed drive arrangement for
optimum efficiency, easy maintenance, and positive circulation for heating or cooling
medium.
The Trough and Blades design radically improves trough mounting and tilting. Built in
piping, straddle mounted gearing and anti-friction bearings improve performance and
safety. Tilting mechanism, automatic lubrication for bearings and gearing, rigidity of
construction, and scientifically correct blades maximize performance.
