The machine is selld to dumpling of this embodiment, still have the function of selling the dumpling, when this dumpling machine received the information that the user purchased the dumpling, begin to make the dumpling and carry to getting meal mouthful to take away for the user after its cooked packing, perhaps also can make the dumpling in advance at a certain time period, and with the dumpling cooked after save in dumpling cooking device 8, when buying the dumpling for the user, the dumpling in dumpling cooking device 8 reentrant make a meal device 9 packs, the packing finishes the back and carries to getting meal mouthful, take away for the user. The selling mechanism (not shown) of the dumpling selling machine is realized by adopting the prior art, and the specific structure and the operation principle are not described herein.

The flour storage device 1 is arranged at the bottom inside the shell, so that the stability of the whole dumpling vending machine can be ensured even if a large amount of flour is stored in the flour storage device 1. Referring to fig. 2, the flour storage device 1 includes a storage box 101, a conveying mechanism and a discharging mechanism, the storage box 101 is used for storing flour, the conveying mechanism connects the storage box 101 and the discharging mechanism, the conveying mechanism is used for conveying flour in the storage box 101 to the discharging mechanism, preferably, the conveying mechanism includes a fourth motor (not shown) and a conveying hose 102, a spiral conveying spring coil perpendicular to the radial direction of the hose is arranged in the conveying hose 102, the fourth motor drives the spiral conveying spring coil to rotate, one end of the conveying hose 102 is located in the storage box 101, when the spiral conveying spring coil rotates, raw materials in the storage box 101 are extracted and conveyed to the discharging mechanism along the conveying hose 102, the discharging mechanism is arranged at a feed inlet of the dough kneading device 3, the discharging mechanism includes a temporary storage bin 103 and a weighing device 104, the temporary storage bin 103 includes a raw material inlet and a raw material outlet, the weighing device 104 measures the weight of flour in, the discharging mechanism releases flour in the temporary storage bin 103 when the weight measured by the weighing device 104 reaches a threshold value, so that the flour in the temporary storage bin 103 falls into the dough kneading device 3 from a feeding hole of the dough kneading device 3, preferably, the weighing device 104 is a weighing sensor, the temporary storage bin 103 comprises a suspension bracket 105, the temporary storage bin 103 is vertically suspended and fixed on the weighing sensor through the suspension bracket 105, the weighing sensor is horizontally arranged on the fixing mechanism 106 to ensure the weighing accuracy, the fixing mechanism 106 is used for establishing the connection relationship between the weighing sensor and other components except the flour storage device 1, and the fixing mechanism 106 can be fixed on the shell.
