Detailed Description

Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of the embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1 to 2, the jet food baking oven provided by the present invention includes a material channel assembly 110, a baking box 120, a heating box 130, a blower 140, an air inlet pipe 150, and an air recovery device.

The material channel assembly 110 is at least partially located in the oven 120, and an air inlet and an air outlet are formed at the top of the oven 120 at intervals. The oven 120 has a housing 121.

One end of the fan 140 is connected with the heating box 130, the other end is connected with the first end of the air inlet pipeline 150, the second end of the air inlet pipeline 150 is connected with an air inlet at the top of the baking box 120, the first end of the air outlet pipeline 160 is connected with the heating box 130, and the second end is connected with an air outlet at the top of the baking box 120.

The air recovery device includes an air outlet duct 160, a box-like liner 123, and two deflector blocks 125. The top of the liner 123 is connected to the top of the housing 121. The guide blocks 125 are attached to the bottoms of two opposite inner side walls of the housing 121 along the length direction, and the top of each guide block 125 is an inclined plane. A gap exists between the side wall of the inner container 123 along the length direction and the side wall of the housing 121 of the oven along the length direction. The hot air flowing through the duct assembly 110 flows to both sides of the duct assembly 110 and then flows upward from the gap between the housing 121 and the liner 123, and the guide block 125 plays a guide role.

Referring to fig. 3, a liner inlet 1231 is provided at a position corresponding to the air inlet at the top of the liner 123, a horizontally outwardly extending clamping portion 1232 is provided at an edge of the liner inlet 1231, and the clamping portion 1232 is connected to the top of the housing 121. The bottom of the liner 123 is provided with a liner outlet 1233, and two opposite inner side walls of the liner outlet 1233 are provided with connecting parts 1234 extending in opposite directions. Two recovery guide plates 1235 which are connected in an angle mode are arranged beside the inner container inlet 1231 and correspond to the air outlet, the top height of each recovery guide plate 1235 is smaller than the height of the inner container inlet 1231, and side recovery openings 1236 are formed at two ends of each recovery guide plate 1235. The hot air flows upward from the gap between the casing 121 and the liner 123 to the side recovery port 1236, then flows along the recovery guide plate 1235 to the air outlet, and then returns to the heating box 130 through the air outlet duct 160.

So that the hot air flows to the material channel assembly 110 to be fully contacted with food, flows to two sides of the material channel assembly 110, flows upwards from the gap between the shell 121 and the liner 123, flows to the air outlet along the collecting guide plate 1235 from the side collecting hole 1236, and finally returns to the heating box 130 through the air outlet pipeline 160. Therefore, the hot air is fully contacted with the food, the processing efficiency is improved, the resource waste is reduced, the air pollution is avoided, and the hot air can be recycled.

In this embodiment, the air recovery device further includes an air inlet baffle 122 and a deflector 124 disposed in the housing 121 of the oven 120. The air inlet baffle 122 is fixed on the inner side wall of the inner container 123, and the upper end of the flow guiding device 124 is connected with the connecting part 1234 of the inner container 123.

The air inlet baffle 122 is disposed in the oven 120 and below the air inlet, the air guide 124 is disposed in the oven 120 and below the air inlet baffle 122, and the air inlet, the air inlet baffle 122 and the air guide 124 are vertically spaced from each other. The fan 140 makes the hot air heated by the heating box 130 enter the baking box 120 from the air inlet through the air inlet pipeline 150, and then the hot air flows to the upper part of the flow guiding device 124 from two sides or four sides of the air inlet baffle 122 under the resisting action of the air inlet baffle 122, so that the hot air is uniformly distributed above the flow guiding device 124, the baking is uniform, and the reject ratio of products is reduced. The flow guiding device 124 directly transmits the hot air to the upper part of the material channel assembly 110, so that heat can be quickly transmitted to the food, and energy loss is reduced.

Referring to fig. 4 and 5, the flow guiding device 124 includes a base plate 1241 and a plurality of hollow flow guiding columns 1242 connected to the base plate 1241. The base plate 1241 is a rectangular plate, and is provided with a plurality of slots, the flow guiding columns 1242 are vertically connected with the base plate 1241, and the upper ends of the flow guiding columns 1242 are connected in the slots of the base plate 1241. Two sides of the substrate 1241 are positioned above the connection part 1234 so as to be slidably connected to the connection part 1234.

The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions or improvements within the spirit of the present invention are intended to be covered by the claims of the present invention.
