A cotton candy preparing device, comprising:

• a rotary pot that is formed of a pot upper portion and a pot bottom portion,
• wherein the pot upper portion has a loading port at an upper end thereof and a tubular inner wall below the loading port,
• wherein a lower end of the tubular inner wall has a conically shaped expanded inclined portion that expands downwards, and a plurality of plate-shaped ribs are provided on the conically shaped expanded inclined portion so as to project towards a center of the rotary pot,
• wherein lower ends of the plate-shaped ribs contact a disc-shaped heating plate provided on a center of an upper end of the pot bottom portion or forms a slight gap between the disc-shaped heating plate and the plurality of plate-shaped ribs,
• wherein a ring member is provided on an outer circumference of a lower end of the conically shaped expanded inclined portion at a lower end of the pot upper portion,
• wherein the ring member has a bore diameter such that an inner circumference of the ring member overlaps a circumferential edge of the disc-shaped heating plate,
• wherein the ring member includes a plurality of first expanded portions that are formed as cutouts in the ring member each extending radially outwards in a fan shape from an inner edge of the bore diameter,
• wherein the plurality of first expanded portions each include a second expanded portion that is formed as a cutout in the ring member further radially outward into a fan shape from the bore diameter, and
• wherein an interior space and an outer circumferential exterior portion of the rotary pot are allowed to communicate with each other by way of a gap that is formed in an upper surface of the ring member from an outer circumferential end of each second expanded portion.
