Modes of operation
During operation, the machine is operated in different modes:
Heating mode
Once machine is turned on, it automatically starts to heat up. Upon
reaching certain temperature machine switches automatically to popping
mode.
Popping mode
This is the main operating mode. Machine operates in cyclic way, process-
ing corn kernels batch by batch. Each cycle consists of three stages:
1.
Feeding
– auger rotates, pushing corn kernels into the chamber.
2.
Popping
– corn kernels are being heated up in the chamber, even-
tually being blown out from the chamber once popped.
3.
Purging
– turbine is accelerated to higher speed in order to blow
everything that are left in the chamber, i.e. un-popped kernels, dust
and other scrap.
Pause mode
Machine doesn’t process corn in this mode, but maintains temperature in
the chamber; popping process can be resumed at any time. The sifter
stops after 3 minutes of pause mode.
Cooling mode
Before turning off, machine must be cooled down. In cooling mode heating
elements are completely de-energized; turbine keeps running, cooling down
the machine. Once temperature drops low enough, machine is turned off
automatically.
