[0029] The present invention also provides a method for using the sweet potato roasting and selling machine, and the specific method comprises the following steps:

[0030] S1. First, the sweet potato is placed in a microwave housing, and then the microwave housing of the sweet potato is placed in the loading housing through the feeding port. When storing, the microwave housing of the sweet potato can be rotated by moving the moving plate;

[0031] S2, the installed microwave shell of the sweet potato falls into the guide shell, the microwave shell of the installed sweet potato is controlled to rotate by the support roller, the spray plate sprays water toward the microwave shell of the installed sweet potato, and the microwave shell of the installed sweet potato is clamped between the first baffle plate and the second baffle plate for microwave heating, so that the sweet potato is heated to 7-8 degrees of maturity;

[0032] S3, the microwave shell of the reheated sweet potato falls from the buffer box into the shelling station, and then the microwave shell is split by two symmetrically arranged electromagnetic suction plates, so that the sweet potato remains in the shelling station due to the fixed steel needle, and then the rotating wheel is controlled to rotate, so that the sweet potato in the shelling station moves to the shelling station, and then the second electric push rod is extended to install the sweet potato in the hot air baking shell;

[0033] S4, when the sweet potatoes in the hot air baking shell pass through the hot and cold baking mechanism, the corresponding fourth electric push rods and the fifth electric push rods are extended, and hot air is blown into the corresponding first connection box through the hot air blower, and the hot air is circulated in the first connection box and the second connection box in turn through the multiple connection pipes, and finally discharged through the exhaust pipe;

[0034] S5. The sweet potatoes baked by the hot air baking mechanism fall into the dumping chute of the discharging and packaging mechanism under the rotation of the rotating wheel. The sixth electric push rod is extended, so that the push rod moves the sweet potatoes toward the folding cardboard, and causes the folding cardboard to extend to wrap the sweet potatoes. Finally, the sweet potatoes wrapped by the folding cardboard fall from the discharging chute into the discharging hopper.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The uniqueness of the present invention lies in its efficient sweet potato processing process. By placing the sweet potatoes one by one in the inclined channel constructed in the loading shell, and using the second rotating roller to drive the second toggle plate to move along the preset trajectory, this design not only promotes the natural rotation of the sweet potatoes on the driven roller, but also significantly enhances the absorption efficiency of the heat absorbing plate for the sweet potato heat, thereby optimizing the refrigeration effect and reducing nutrient loss. It is particularly worth mentioning that when the sweet potato gets stuck in the channel, by increasing the rotation speed of the second rotating roller, the second toggle plate can exert greater force to cause the sweet potato to rotate, effectively solving the jamming problem. In addition, the sweet potato can be placed in a cylindrical microwave housing, and its superior rotation performance further enhances the refrigeration effect.

[0037] 2. The microwave pre-preparation mechanism of the present invention exhibits excellent pre-heating capacity and can heat sweet potatoes to 70% to 80% doneness, greatly shortening the subsequent baking time and reducing energy consumption. Its internal structure is cleverly designed, and the alternating opening and closing of the first baffle and the second baffle are used to achieve continuous microwave pre-preparation of sweet potatoes, significantly improving the efficiency of serving meals. In addition, before microwave pre-preparation, the first electric push rod controls the support roller to extend and rotate, and the spray plate sprays water on the surface of the sweet potatoes, which accelerates the microwave pre-preparation process and further improves the serving speed.

[0038] 3. The sweet potato transfer mechanism of the present invention innovatively realizes the rapid replacement of the sweet potato shell and the seamless conversion from the microwave shell to the hot air baking shell. The sweet potato is fixed by a fixed steel pin, and the electromagnetic suction plate and the third electric push rod work together to easily separate the microwave shell. Then, the sweet potato is quickly wrapped in a new hot air baking shell through the cooperation of the rotating wheel and the second electric push rod. This design not only optimizes the hot air baking conditions, but also significantly improves the efficiency and quantity of food delivery, and reduces the waiting time for customers.

[0039] 4. The design of the hot air baking mechanism is equally ingenious. Hot air is injected into the first connecting box through the hot air blower. The hot air circulates in the connecting pipe and the connecting box and is finally discharged through the exhaust pipe. This process ensures the uniform distribution of hot air in multiple hot air baking shells, greatly improving the heat utilization rate and accelerating the drying process of the sweet potato skin.

[0040] 5. The perfect combination of the discharging and packaging mechanism and the hot air baking shell realizes the automatic packaging of sweet potatoes. The baked sweet potatoes fall into the dumping chute, and the sixth electric push rod drives the push rod to push the sweet potatoes to the folded paper, which then unfolds and wraps the sweet potatoes and finally falls into the discharging hopper. This design not only simplifies the packaging process, but the stretched conical folded paper provides a good wrapping effect, and the wrinkles on its surface effectively prevent the risk of scalding, bringing users a more convenient and safe experience.

DETAILED DESCRIPTION

[0081] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0082] like Figure 1-Figure 34 As shown, the present embodiment provides a sweet potato roasting and selling machine, comprising a first shell 801, on which an operation panel 803 is mounted, inside of which an internal support plate 802 is mounted, and on the outer side of which a discharge hopper 804 is mounted, and a feeding device 100 comprises a feeding shell 101, in which two conveying channels are provided, a cooling plate 104 is mounted on the inner wall of the feeding shell 101, and a heat dissipation external machine 105 is mounted on the outer side of the feeding shell 101, and the cooling plate 104 is connected to the heat dissipation external machine 105.

[0083] Two third mounting grooves 112 are also provided in the loading shell 101. Each third mounting groove 112 is arranged opposite to the corresponding first mounting groove 107.

The shifting belt 114 is also installed with a plurality of second shifting plates 115. The second shifting plates 115 are in an arc shape.

[0084] In this embodiment, the sweet potato can rotate under the movement of the first toggle plate 111 and the second toggle plate 115, so that the heat in the sweet potato can be better dissipated, thereby reducing the respiration of the sweet potato, so that the temperature of the sweet potato can always be maintained at a temperature that is more convenient for storage, thereby effectively reducing the probability of sweet potato damage, and making the quality of the roasted sweet potato of the present invention more stable.

A plurality of first toggle plates 111 are installed on the first rotating roller 110. Both the first toggle plate 111 and the second toggle plate 115 are arc plates. In this embodiment, both the first toggle plate 111 and the second wave plate are rubber plates, and the surfaces thereof are provided with "human" shaped patterns.

[0086] In this embodiment, the multiple conveying channels are in the shape of the letter "U". Of course, a serpentine conveying channel can also be set. When using a serpentine channel, it should be ensured that a corresponding toggle plate is installed in each individual channel in the serpentine channel to realize the function of the toggle plate to toggle the sweet potato to rotate.

[0087] In this embodiment, a compressor is also installed between the cooling plate 104 and the heat dissipation external unit 105.

[0088] The present invention places the sweet potatoes one by one in the inclined channel constructed in the loading shell 101, and uses the second rotating roller 113 to drive the second toggle plate 115 to move along a preset track. This design not only promotes the natural rotation of the sweet potatoes on the driven roller 108, but also significantly enhances the absorption efficiency of the heat of the sweet potatoes by the heat absorbing plate, thereby optimizing the refrigeration effect and reducing nutrient loss. It is particularly worth mentioning that when the sweet potatoes get stuck in the channel, by increasing the rotation speed of the second rotating roller 113, the second toggle plate 115 can exert greater force to cause the sweet potatoes to rotate, effectively solving the problem of getting stuck. In addition, the sweet potatoes can be placed in the cylindrical microwave housing 600, and its superior rotation performance further improves the refrigeration effect.

The driving rod of the first electric push rod 214 is fixedly connected to the mounting bracket 215.

[0090] A spray plate 211 is also installed in the guide shell 201, and the spray plate 211 is arranged in cooperation with the support roller 216.
