The GRL-1000 Laboratory Dough Mixer.

A laboratory pin mixer capable of mixing doughs from 300 to 1,000 g. flour is described. The basic mixing action is modeled on that of the smaller GRL-200 pin mixer. The scaled-up Model 1000 mixer is driven by a variable speed motor and provides for operation at any one of eight mixer pin speeds ranging from 37 to 160 r.p.m. It is thus suitable for baking methods calling for slow or high-speed mixing conditions. A signal representing the torque during mixing is obtained from the motor armature current and may be fed to a recorder to give a mixing curve. A redesigned gear and bearing mechanism in the mixing head has increased the mechanical efficiency very significantly over that of the original GRL-200 mixer.
