Turbine (Blower); Chamber; Sifter And Scrap Tray - RoboLabs Robopop 75 User Manual

3.1

Turbine (blower)

The turbine provides constantly circulating airflow inside the machine.
This is a direct type drive; the blower sits on motor's shaft. Rotational
speed is controlled by the main controller of the machine.
3.2

Chamber

This is where popping happens. Airflow circulates through the chamber;
air is being heated by heating elements. In the chamber's lower part there
is a bowl with special shaped holes that causes air vortex. During ma-
chine operation corn kernels are being fed into the chamber; kernels are
being heated up, and finally, immediately blown away from the chamber
once popped. Chamber can be easily accessed through the door provided.
Halogen lamp illuminates chamber inside, helping operator to control the
process inside. Chamber is equipped with optical sensor (1) and temper-
ature sensor (2):
Optical sensor is to monitor processes in the chamber. Popper uses sig-
nal from this sensor in order to maintain smooth and effective operation
process. Temperature sensor is to control the temperature in the chamber.

Sifter and scrap tray

Sifter is a rotating drum with holes that screens un-popped kernels, partly
popped popcorn, and other small fractions into scrap tray located under
the sifter. Scrap tray is easily removable.
