Design and principle of operation

Main components of the machine are shown on Fig. 1. Motor (13) with turbine (25) causes air
circulation inside the machine. Air goes from the turbine to the working chamber (20), then to
the heating elements area (24), where it is heated, and finally goes back to the turbine. In the
low part of the working chamber there is perforated bowl (23), that has many holes of special
shape, which cause air vortex inside the chamber as airflow goes through the bowl. Working
chamber is closed with hatch (21), fixed with four latches (19).
Corn kernels are put in the corn bins (3) (4). Each bin is equipped with motor (18), level
sensor (18), and an auger inside the bin. Motor drives the auger, rotating auger pushes corn
kernels to the supply tube (15), which leads to the working chamber. In the chamber the
kernels are heated up, and then eventually pop and exit to the sifter (11).
Crumb tray (2) collects small particles of popcorn being screened in the sifter. Level sensor
(12) controls the level of popcorn collected in the cart (not shown).
Oil pump compartment (1) accommodates oil pump. Special salt is put in the salt bin (7) with
an auger inside. Motor (9) drives the salt auger, which pushes the salt from the bin. Blower (8)
blows the salt through removable salt supply tube (10) on popcorn inside the sifter.
Most electric components of the machine are accommodated in upper (6) and lower (14)
electric panels. Upper panel includes control panel (5). START push button turns the machine
on; SIFTER push button is used to stop sifter for short time during operation; OIL WARM
switch turns on and off heating in the oil cabinet.
Emergency stop switch turns the machine off at any moment.
