McNab SKID systems are customized for the particular application the brewer has need to control.  While the particular blending process will vary depending on the brew being processed, McNab SKID systems are ideal for the monitoring and controlling of pitching, cropping, transfer, blending, as well as other custom SKIDs.

Before you begin, take a look at the interactive chart which illustrates applications of McNab equipment and provides links to specific model information.

Complete, Accurate Proportional Blending

The monitoring is performed by the McNab fluid analyzers, which examine such properties as suspended solids concentration, particle size, clarity, chemical concentration, optical density and others.

The monitors employ an across-the-pipe measuring technique, whereby a beam of collimated light is shone through the process line and picked up by a photo-electric scanner. The scanner processes the signal and transmits the real-time data to an indicator/controller cabinet, which processes the signals and compares them to established set-points. As the brew's properties deviate from the set point, output control signals from the cabinet are continuously varied to control the flow of the blending agents into the process line.

The measuring technique employed is dependant on the process being monitored. McNab analyzers employ variety of measuring techniques, including nephelometric (90^o scatter), back-scatter, forward scatter, ratio, ultraviolet and near-infrared measurements.

Other Custom SKIDs

With nearly four decades of experience in beer process monitoring and control, McNab has the capabilities to custom-design the SKID process perfectly suited for the needs of today's breweries.  McNab SKIDS can be customized to control the brewing process by monitoring suspended solids concentration, particle size, clarity, chemical concentration, optical density and/or other characteristics of the in-line beer.
