[0053] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0054] Specific embodiment 1 of the continuous cooking machine of the present invention:

[0055] like Figures 1 to 3 As shown, the continuous cooking machine includes a cylindrical pot body 1, in which a rotating shaft 2 is rotatably mounted. The continuous cooking machine in this embodiment is horizontal, the rotating shaft 2 is horizontally arranged, the pot body 1 extends axially along the rotating shaft 2, and one rotating shaft is arranged. A plurality of feed ports are arranged on the top of the pot body 1, and a dish outlet 11 is arranged at the bottom of one end of the pot body 1. A plurality of feed ports are arranged, and a storage tank 12 is arranged at each feed port. The storage tank 12 can be used to store semi-finished dishes, seasonings, oil, etc. A valve 13 is arranged at the bottom of the storage tank 12, and the opening and closing of the outlet of the storage tank 12 can be controlled by the valve 13, thereby controlling the feeding into the pot body, and controlling the feeding amount by controlling the opening time of the valve 13. In other embodiments, in order to facilitate the accurate control of the amount of feeding, a quantitative feeding device can also be arranged at the bottom of the feeding box, such as the automatic quantitative feeding mechanism used in the publication number CN109645862A.

[0056] The feed inlets are arranged at intervals along the axial direction of the rotating shaft 2. During the cooking process, since the rotating shaft 2 rotates continuously during the cooking process, the vegetables added from the storage tank 12 far away from the vegetable outlet 11 stay in the pot body 1 for a longer time and can be heated for a longer time. According to the cooking time of the vegetables, vegetables that require a longer heating time are selected to be stored in the storage tank 12 far away from the vegetable outlet 11, and vegetables that require a shorter heating time are selected to be stored in the storage tank 12 near the vegetable outlet 11. In other embodiments, according to actual needs, multiple storage tanks can also be set at one position in the axial direction of the rotating shaft; or all storage tanks can be set at the same position in the axial direction of the rotating shaft, in which case the heating time of the vegetables in the pot body is the same.

[0057] A stir-fry blade 3 for stir-frying the ingredients in the pot body 1 and pushing the ingredients to the food outlet 11 of the pot body 1 is fixed on the rotating shaft 2. The stir-fry blade 3 is a spiral blade wound around the outer periphery of the rotating shaft 2. A driving motor 4 for driving the rotating shaft 2 to rotate is provided at one end of the rotating shaft 2 extending out of the pot body 1. During the rotation of the rotating shaft 2, the stir-fry blade 3 can stir-fry the ingredients in the pot body 1 and transport them to the end where the food outlet 11 is set.

[0058] In order to reduce heat loss, the present embodiment adopts a heating method inside the pot body 1, such as Figure 2 and Figure 3 As shown, the rotating shaft 2 includes an inner shaft tube 21 and an outer shaft tube 22. The inner shaft tube 21 has a rotating shaft reflux channel 211. The annular channel between the inner shaft tube 21 and the outer shaft tube 22 forms a rotating shaft heating channel 221. Heat can be transferred to the pot body 1 through the outer shaft tube 22 of the rotating shaft 2, thereby improving the heat transfer efficiency.

[0059] The stir-fry blade 3 is a hollow blade, and the inside of the stir-fry blade 3 is connected with two channels in the rotating shaft 2. A heat flow channel 31 for fluid to pass through is formed inside the stir-fry blade 3. The heat flow channel 31 extends from one end of the stir-fry blade 3 to the other end in a spiral shape. The stir-fry blade 3 heats the inner cavity of the pot body 1 through the hot fluid in the heat flow channel 31, so that the stir-fry blade forms a fluid heating blade with a heat flow channel. A blade connecting port 222 connected to the inside of the stir-fry blade 3 is provided on the wall of the outer shaft tube 22. In this embodiment, a plurality of blade connecting ports 222 are arranged along the axial direction of the rotating shaft 2. In this embodiment, a connecting pipe 23 connecting the inner shaft tube 21 and the stir-fry blade 3 is connected to the wall of the inner shaft tube 21. One end of the connecting pipe 23 is connected to the rotating shaft reflux channel 211, and the other end is connected to the heat flow channel 31 in the stir-fry blade 3. In this embodiment, one connecting pipe 23 is provided, and the connecting pipe 23 is provided at one end of the rotating shaft 2 near the dish outlet 11.

[0060] The driving motor 4 is arranged at one end of the rotating shaft 2 close to the dish outlet 11, and a rotating connector 5 is arranged at one end of the rotating shaft 2 away from the dish outlet 11. The rotating connector 5 includes a rotating shaft connecting part and a heat source connecting part that rotates relative to the rotating shaft connecting part shell. Two interfaces are arranged on the heat source connecting part, namely a heat source interface connected to the rotating shaft heating channel 221 and a return water port connected to the rotating shaft return channel 211. The heat source interface is connected to the external heat source, and the heating fluid enters the rotating shaft heating channel 221. The return water port is connected to the return water pipeline, and the fluid in the rotating shaft return channel 211 flows out. The rotating connector 5 is a two-way flow rotating connector 5 in the prior art, and the specific structure is not repeated. In this embodiment, the driving motor 4 directly drives the rotating shaft 2 to rotate through a reducer. In other embodiments, the driving motor can drive the rotating shaft to rotate through a belt, a gear, etc. In order to realize automatic control, the continuous cooking machine in this embodiment is also provided with a cooking machine controller, and the cooking machine controller controls the automatic operation of the driving motor and the valve.

[0061] In this embodiment, a driving motor 4 is arranged at the end of the rotating shaft 2 close to the dish outlet 11, and a rotating connector 5 is arranged at the end away from the dish outlet 11, so as to avoid interference between the driving mechanism and the rotating connector 5 and facilitate arrangement. At the same time, the external hot fluid has a higher temperature after entering the pot body 1 through the rotating connector 5. The vegetables at a position away from the dish outlet 11 are relatively raw, so the heat can be fully utilized to heat the vegetables.

[0062] In addition, in order to facilitate the cleaning of the pot body, in this embodiment, a cleaning water inlet (not shown in the figure) is provided on the pot body for injecting water into the pot body to clean the inner cavity of the pot body. A control valve is provided at the cleaning water inlet, and the control valve is connected to an external water pipe to control the water inlet of the cleaning water inlet. The cleaning water inlet is located at the end of the pot body away from the dish outlet. When cleaning, the rotating shaft rotates to drive the stir-fry blades, so that the stir-fry blades stir the cleaning water flow in the inner cavity of the pot body.

[0063] The continuous cooking machine of the present invention heats the inner cavity of the pot body 1 by means of the rotating shaft 2 and the stir-fry blades 3 arranged in the pot body 1. The heat dissipated by the rotating shaft 2 and the stir-fry blades 3 is in the pot body 1, thereby reducing energy waste. In addition, by means of heating by the stir-fry blades 3 and the rotating shaft 2, each part of the inner cavity of the pot body 1 is heated more evenly, thereby shortening the cooking time.

The rotating shaft in this embodiment is divided into two sections, which are respectively fixed at the two ends of the spiral blade. In this embodiment, the rotating shaft at the two ends of the spiral blade is respectively provided with a rotating shaft reflux channel and a rotating shaft heating channel. In other embodiments, only one end of the spiral blade can be fixed, and the other end of the spiral blade can be suspended.

The stir-fry blades 303 on the two rotating shafts 302 intersect with each other. The stir-fry blades 303 have an inclined surface 3031 for pushing the material toward the direction of the dish outlet during the rotation process. During the rotation of the rotating shaft 302, the stir-fry blades 303 can push the material toward the dish outlet 311, and the stir-fry blades 303 that intersect with each other can stir-fry the food more evenly. The wedge-shaped blades are also hollow blades, such as Figure 5As shown, the shaft return channel 3211 in the inner shaft tube 321 and the shaft heat supply channel 3221 between the inner shaft tube 321 and the outer shaft tube 322 are both connected to the inside of the stir-fry blade 303, and a heat flow channel 331 is formed inside the stir-fry blade 303, wherein the inner shaft tube 321 is connected to the heat flow channel 331 through a connecting tube 323, and in order to make the stir-fry blade 303 heated evenly, the connecting tube 323 extends into the stir-fry blade 303.
