For example, the turn control module 500 can control the movement device 200, such that the movement device 200 first fetches from the storage device 100 and moves the first food item 20 to one of the at least one delivery portion 310, and the turn control module 500 can then control the heating device 400 and the delivery portion 310 to perform heating and delivery procedures on the first food item 20. While the first food item 20 is being processed in the delivery portion 310, the turn control module 500 can in turns control the movement device 200, such that the movement device 200 returns to the position corresponding to the storage device 100, and fetches from the storage device 100 and moves the second food item 20 to the other of the at least one delivery portion 310, and then the turn control module 500 can control the heating device 400 and the delivery portion 310 to perform heating and delivery procedures on the second food item 20. While the second food item 20 is being heated and delivered, if the first food item 20 has been delivered, the turn control module 500 can in turns control the movement device 200, such that the movement device 200 returns to the position corresponding to the storage device 100, and fetches from the storage device 100 and moves the third food item 20 to the delivery portion 310 previously holding the first food item 20, and the turn control module 500 can then control the heating device 400 and the delivery portion 310 to perform heating and delivery procedures on the third food item 20. In this embodiment, the food items 20 are heated sequentially and separately; however, in an alternative embodiment, the food items 20 are delivered sequentially whereas are heated and delivered simultaneously, and thus the consumers shall obtain the food items 20 simultaneously.

For example, the turn control module 500 can in turns control the movement device 200, such that the movement device 200 in turns fetches from the storage device 100 and moves two food items 20 into two placement portions, and sequentially places the two food items 20 on the two placement boards 311 of the two at least one delivery portion 310. Further, the turn control module 500 can control the at least one injection member 430 of the heating device 400 and in turns move the injection member 430 to be corresponded to the at least one food item 20, so as to in turns heat the food held in the at least one food item 20.
In this embodiment, the steam portion 410 and the hot water portion 420 are configured to sequentially inject steam and hot water into the at least one food item 20 on the placement board 311 corresponding thereto so as to heat the food in the at least one food item 20. For example, when the at least one food item 20 is placed on the placement board 311, the corresponding injection member 430 moves and inserts into the at least one food item 20, and the steam portion 410 then first injects high-temperature steam into the at least one food item 20 through the at least one injection member 430 to quickly defrost the frozen food in the at least one food item 20 and then stops outputting steam. Next, the hot water portion 420 injects hot water into the at least one food item 20 through the at least one injection member 430, such that the frozen food is heated at an appropriate speed in the hot water. After heating is completed, the at least one injection member 430 moves away from the at least one food item 20, and the at least one food item 20 in the delivery portion 310 at this point has undergone the heating procedure and are ready to be delivered.
