EQUIPMENT DESCRIPTION

The Groen GFK-20 cooker/mixer consists of a water-jacketed kettle with a 
motor-driven mixer. The 20 quart tilting kettle is equipped with electronically 
controlled electric heaters for the jacket.
The kettle of models GFK-20-110V and GFK-20-220V is constructed of stainless 
steel welded into one piece. The body has a reinforced rim and a butterfly-
shaped pouring lip. It is fitted with an integral water jacket. The kettle exterior 
has a bright semi-deluxe finish. The kettle’s pouring height allows filling pans up 
to 4 inches high on a table top.
The kettle’s internal electric heaters provide uniform heat in three stages, with 
jacket temperature control over the range of 140ºF to 180ºF (60ºC to 80ºC). 
In addition to the three-stage adjustable thermostat for operating control, the 
unit has a high limit thermostat, as a safety feature, plus an indicator lamp and 
water gauge glass, which is used to monitor kettle operation.
The Agitator fits over the agitator post inside the kettle. Mixing is controlled with 
a power switch. The switch doubles as a circuit breaker for motor protection. 
The agitator continuously sweeps the side and bottom of the kettle.
Electric power for the kettle and mixer is supplied through a plug-in power cord, 
which is furnished with the unit. 

GFK-20-110V: 6’ - 12 AWG cord and 20 amp, 3-wire straight blade plug
GFK-20-220V: 6’ - 12 AWG cord and 15 amp, NEMA L6-15 plug
