3 Design and principle of operation

3.1 Main components

Main components of machine is represented on Fig. 1.
Motor with turbine causes air circulation inside the machine. Air goes from the turbine to the
working chamber, then to the heating elements area, where it is heated, and finally goes back to
the turbine.
Popcorn kernels is loaded in the corn bin with feeder, see Fig. 2. The feeder consists of feeding
motor and an auger inside the bin. The motor drives the auger, which pushes corn in the chamber.
Fixed guard covers the rotating auger to avoid direct contact.
Corn bin optical sensor trips whenever the bin becomes empty. Once the sensor is tripped, the
machine notifies an operator that the bin must be refilled.
