Abstract
An improved cotton candy machine melts sugar by inductively heating a spinning head and preferably a perforated spinner band on the spinner head. An induction heater is disposed in a machine base beneath the rotating spinner head and excites the band to a heat range for melting and spinning elongated molten strands of cotton candy from raw sugar. Electric heater strips, electric conduits, electric terminals, electric slip rings and electric spring-loaded brushes are all eliminated. Methods are disclosed.
Claims4
A cotton candy machine comprising:
- a base;
- an accumulating tub mounted above said base, said tub having a bottom wall, side walls extending upwardly from the bottom wall, and an opening formed in the bottom wall;
- a spinner head for heating and spinning cotton candy from sugar and being mounted for rotation within said tub;
- a perforated spinner band of ferrous material mounted for rotation with said spinner head within said tub;
- and
- an induction heater oriented to direct an energy field toward said spinner head through the opening in said tub for heating said spinner band to melt said sugar in said head so it can be spun out as molten strands to form cotton candy.
A cotton candy machine comprising:
- a base;
- an accumulating tub mounted above said base, said tub having a bottom wall including a concave portion extending up into said tub, side walls extending upwardly from the bottom wall, and an opening formed in the bottom wall;
- a spinner head for heating and spinning cotton candy from sugar and being mounted for rotation within said tub;
- a perforated spinner band of ferrous material mounted for rotation with said spinner head within said tub;
- and
- an induction heater aligned with the opening in said tub, and operable to direct an energy field toward said spinner head through the opening for heating said spinner band to melt said sugar in said head so it can be spun out as molten strands to form cotton candy.
A method of producing cotton candy including the steps of:
- providing a base;
- providing an accumulating tub above said base, said tub having a bottom wall, side walls extending upwardly from the bottom wall, and an opening formed in the bottom wall;
- rotating a cotton candy spinner head within said tub;
- energizing an induction heater and aligning said induction heater with the opening in said tub to direct an energy field toward said spinner head through the opening in said tub and heat a portion of said spinner head for melting sugar in said head;
- and
- spinning molten cotton candy from said head for accumulation in said tub.
