A grain-popping machine and associated pod-based popping method is disclosed. The grain-popping is configured to receive a pod. Each pod includes a plurality of cells, with each cell preferably containing a single grain kernel or seed, flavoring, and a cooking medium such as oil or shortening. In a preferred embodiment, the pod is loaded into the grain-popping machine through a slot so that it is held in position adjacent to a heating element. The heating element is activated to begin a popping sequence. When each grain kernel or seed in the pod reaches popping temperature, it absorbs the flavoring in its cell and ejects through the bottom of the pod, which can be weakened to ease ejection, into a bowl positioned in a receiving area of the grain-popping machine. The pod is then removed and disposed of.

A dried rice gel production method increasing the Young's modulus of a raw material rice gel to harden the raw material rice gel, thereby obtaining a hardened rice gel. The method further includes drying the hardened rice gel to obtain a dried rice gel. To obtain the hardened rice gel, the raw material rice gel may be hardened such that the Young's modulus of the raw material rice gel exceeds a predetermined value. The predetermined value may be a value of 160 kilopascals or more, or may be 440 kilopascals or more.

Systems and methods for preventing dumping of a popping kettle in a popcorn machine above a preset temperature to facilitate fire containment are disclosed herein. In some embodiments, a popcorn machine can include one or more temperature control systems to prevent the popping kettle from exceeding a normal operating temperature range. In the event such systems fail, however, embodiments of the present technology include lock systems that will lock the popping kettle in an upright position before the kettle reaches a temperature that will ignite the popping oil. Locking the popping kettle in this manner prevents an operator from inadvertently dumping burning oil onto popcorn piled in the bottom of the cabinet, igniting the popcorn and causing the fire to spread. Locking the kettle can also provide additional time for a fire suppression system to extinguish the fire while it is contained in the kettle.

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.

Disclosed is a heated air popcorn popper which provides a heating base assembly and popping pitcher having an interior popping volume which is detachable from the base assembly for introduction of popcorn kernels. The base assembly providing heated air to the popping pitcher causing unpopped kernels to pop and form popped popcorn. The detachable popping pitcher includes a pitcher lifting handle such that the popping pitcher can be lifted away from the heating base assembly to permit any remaining unpopped or popped kernels to be emptied from the detachable popping pitcher for cleaning.

Popcorn machines having process chambers of increasing volume, and associated systems and methods of operation are disclosed herein. In one embodiment, a popcorn machine includes a tube, a heating element positioned to heat the tube, and an auger positioned at least partially within the tube. The auger can include a central portion extending along a longitudinal axis from a first end to a second end. The central portion decreases in diameter from the first end to the second end, and the central portion and the tube at least partially define an annular popping chamber that increases in volume from the first end toward the second end. A flight extends around the central portion in a helical pattern between the central portion and an inner wall of the tube. In operation, the auger rotates about the longitudinal axis to move ingredients through the heated tube via the flight.

A popcorn kernel popping machine permits a user to insert a popcorn kernel/flavor pod therein and obtain an evenly flavored popcorn product. The popcorn pod can include not only the popcorn kernels, but also liquid and/or solid flavorings which can be distributed to the popped kernels as they exit the popper, thereby coating the popped kernels evenly with the desired flavoring(s). In some embodiments, a popped kernel collection container can be rotated to evenly collect the popped kernels therein during operation of the popcorn popper.
