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.
