2.6 Design and principle of operation
The machine includes the following main components, see Fig. 1: Housing; Chassis with
electric motor and Spinning Head. The spinning head and electric motor are mounted on the
chassis, which itself is connected to the housing by four Spring-mounted Supports. These
supports dampen vibrations and allow the motor to self-balance during operation.
Rubber floss pan supports holds a floss pan (not shown). An electric motor drives the
spinning head at a high rate of speed (see technical specifications). A Stator is mounted on the
chassis to direct air flow in an upward spiral. It is fitted with a silicone Sealing Collar which
seals the gap between the floss pan and the stator in order to prevent sugar from falling onto
the chassis. An adjustable Silicone band covers the intake grill in order to regulate air flow.

The Spinning Head has the following main parts: Impeller; Base-plate; Sidewall with
Heating coil, Slip rings and Cover. Controls panel of the machine include:
Main Switch turns on the electric motor which rotates the spinning head; Heat Switch turns
on the heating coil; Adjustment Knob regulates power to the heating coil and thus controls
its temperature; Voltmeter indicates actual voltage supplied to the heating coil.
Quick Start button 1 temporarily sends maximum power to the heating coil, even when the
electric motor is not running.
The spinning head rotates with the sugar mix inside where the heating coil warms the sugar
up. When the sugar rises above 160°C/320°F, it starts to melt. Due to centrifugal force, the
melted sugar escapes through laser cut slits in the sidewall, where it instantly cools and
crystallizes turning into candy floss. An attached impeller rotates along with the spinning
head, producing a powerful upward airflow. Air enters from below, through the axial grills of
the stator, which can be restricted by the silicon collar. The airflow can lift the cotton candy
several feet in the air. Sugar particles that are too heavy will collect in the floss pan.
