2.5 Modes of operation

Whenever the machine is turned on, it is in one of the following modes of operation.
Heating mode
Once the machine is turned on, it automatically starts to heat up air in the chamber. Upon
reaching certain temperature the machine automatically switches to popping mode.
Popping mode
This is the main mode of operation. Machine processes corn kernels batch by batch, in cyclic
mode. Each cycle consists of three stages:
1. Feeding – hopper auger rotates, pushing corn kernels into the chamber.
2. Popping – corn kernels are being heated up in the chamber, eventually being blown out
from the chamber once popped.
3. Purging – turbine is accelerated in order to blow out everything left in the chamber: un-
popped kernels, dust and other scrap.
Pause mode
Whenever the operator initiates pause, the machine processes current batch of corn, and then
stop feeding next batches of corn. The temperature in the chamber is maintained at the set
value. Popping process can be resumed at any time.
Cooling mode
The machine needs to be cooled down before turning the turbine o . Whenever the opera-
tor initiates cooling mode, heating elements are de-energized; but the turbine keeps running,
cooling down the machine. Once temperature drops low enough, the turbine stops and the
machine turns o automatically.
