Abstract: A single serving-on-demand-popcorn popper employs a flat member with an orifice defining an open-ended chamber of predetermined volume. The member is rotatable about an axis perpendicular to its surface and offset from the chamber. Upper and lower spaced plates sandwich the member to close the open-ended chamber. Passages angularly displaced through the upper plate sequentially communicate with the orifice during its rotation. A passage through the lower plate is aligned with one of the passages of the upper plate. A hopper in constant communication with the other passage in the upper plate gravitationally feeds unpopped kernels of corn into the chamber. A switching circuit interrupts rotation of the member to maintain the orifice in alignment with the passages through the upper plate for preselected periods of time. A blower forces air through the aligned passages in the upper and lower plates and the orifice.
