Abstract: A popcorn extruder includes a feeder, a popping chamber, a heating device, an unloading device, and a discharge tube. The chamber is a vertical cylindrical barrel. Said heating device and said unloading device are installed on top of the barrel and at the bottom of the barrel, respectively. Said feeder has a discharge end connected with the upper-end side wall of the chamber. Said discharge tube has one end installed at the upper-end side wall of the chamber. Said unloading device has a conical structure. Said conical structure is located in the chamber, and said conical structure has the tapered end facing up. Said heating device includes a fan, an air duct and a heater installed in the air duct; said fan is connected with one end of the air duct; and said air duct has the other end inserted in the chamber and is adjacent to the conical structure.
