Figure 4: Main components of the machine
The machine represented on the Fig.4 (floss pan with mesh screen
and clips are not shown): 1 – Lower rubber leg; 2 – Housing; 3 – Trans-
portation handle; 4 – Chassis; 5 – Transport fastening nuts; 6 – Upper
rubber leg; 7 – Spinning head with heating coil; 8 – Tabs; 9 – Brush
units; 10 – Spring loaded supports; 11 – Main power switch; 12 –
Voltmeter; 13 – Adjustment knob; 14 – Heating switch.
Main power switch (11) turns on the motor, and allows to to turn
the heating. Heating switch (14) turns the heating on. Voltmeter (12)
reads the voltage applied to the heating coil. The more the voltage,
the more power delivered to the spinning head. Adjustment knob (13)
is used to adjust the voltage applied to the heating coil. The spin-
ning head (7) rotates with the sugar mix inside where the heating coil
warms the sugar up to its flow point 120–140°C (250–285°F). Due
to centrifugal force, the melted sugar escapes through holes in the
sidewall of the spinning head (7), where it instantly cools and crys-
tallizes turning into candy floss. Two tabs (8) on the spinning head
causes airflow that pushes candy floss to the pan's sidewalls (see
Fig.2), where an operator collects cotton candy with a stick.
