From the corn bin, corn kernels goes to
working chamber, through the corn supply
tube, see Fig. 3.
Perforated bowl has many holes of spe-
cial shape, which cause air vortex inside the
chamber as airflow goes through the bowl.
Due to air vortex, corn kernels are constantly
moving inside the chamber around center of
the bowl. Kernels eventually pop, and then
being evacuated from the chamber by the
means of air flow, through the chamber out-
put.
Baffle divides the chamber for the area
where corn kernels are being heated up, and
the output areaz.
Mesh screen protects internal cavities (in-
cluding heating elements area) from popcorn
dust and scrap accumulation.
Temperature sensor constantly measures temperature of the air in the chamber. Optical sensor
controls corn movement inside the chamber. Machine will not start next batch until a batch of corn
is completely processed, thus avoiding chamber clogging with corn kernels and popcorn.
Chamber lamp illuminates the chamber, so an operator can visually control the process through
the observation port in the chamber door.

Control panel represented on Fig. 4.
HMI panel is used to control the machine,
change the parameters of operation, and so
on.
START push button turns the machine
on.
Emergency stop switch shuts down the ma-
chine immediately at any moment.
