The unit was designed to be run from a two-speed countershaft at 585 and 160 rpm.
This drove, through a two-speed gearbox and a large spur gearwheel, a line shaft mounted below the frame.
To obtain even more boost, two-speed two-stage superchargers were introduced, with an intercooler between the stages.
A two-speed, three-phase motor drove the four speed gearbox to give a total of 8 spindle speeds from 170 to 2160 rpm.
The MBB Series purees, chops, and liquefies ingredients using a two-speed control mechanism.
