[0003] The baking and combustion mechanism of the existing biscuit baking device has a simple structure, and the arrangement of the burners is often a diamond structure, which results in baking gaps in the structure. Therefore, during the baking process, the biscuit mold is not in sufficient contact with the combustion flame, the combustion efficiency is low, and the energy loss is large, resulting in poor biscuit forming effect, and the baked biscuits are not firm and are easy to break; the crushed materials generated after the biscuits are broken remain in the biscuit mold and are difficult to clean, making it difficult to bake the biscuits continuously. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a baking and combustion device with high baking and combustion temperature, strong heat-continuing performance, fuel saving and full and uniform combustion.

[0041] like Figure 1As shown, a baking combustion device includes a combustion pipeline mechanism and a combustion control mechanism;

[0042] The combustion pipeline mechanism includes an air intake pipe 100, a bellows 110, and a pipeline assembly 120 that are sequentially connected. The pipeline assembly 120 includes a front combustion pipe 130 arranged on the outside, a middle combustion pipe 140 arranged in the middle, and a rear combustion pipe 150 arranged on the inside.

The combustion control component 200 includes an internal threaded ball valve 210, a second-level solenoid valve 220 and a pneumatic ball valve 230 connected in sequence. The pneumatic ball valve 230 is provided with a connecting air pipe 240 at one end away from the second-level solenoid valve 220, and the connecting air pipe 240 is connected to the air intake pipe 100.

[0044] The combustion pipeline mechanism has a pipeline assembly 120, and the pipeline assembly 120 includes a front section combustion tube 130 arranged on the outside, a middle section combustion tube 140 arranged in the middle, and a rear section combustion tube 150 arranged on the inside, which can bake and burn the outside, middle and inside of the mold in sequence; when the mold is located at the front section of the pipeline assembly 120, the ignition point of the front section combustion tube 130 corresponds to the outside of the mold, and the outside of the mold can be baked and burned, and the combustion flame spreads to both sides when it hits the outside of the mold, which can preheat the middle of the mold; and when the mold is transported to the middle section of the pipeline assembly 120, The ignition point of the middle section combustion tube 140 corresponds to the middle of the mold, and the middle of the mold is baked and burned, and the combustion flame spreads to the outside and inside of the mold, thereby not only preheating the inside of the mold, but also continuing to heat the outside of the mold, so that the pipeline component 120 has strong continuing heating performance and saves gas energy; similarly, when the mold is located at the rear section of the pipeline component 120, the rear section combustion tube 150 bakes and burns the inner side of the mold; thereby, when the mold is baked and burned, it not only heats up quickly, but also the heat stays for a long time, which can ensure that the biscuits are baked and burned evenly and have a good molding effect.

[0045] The combustion control mechanism includes a filter 170, a valve 180, a first-level solenoid valve 190 and a combustion control component 200 that are connected in sequence.

The mechanism is also provided with a valve 180, a first-level solenoid valve 190 and a combustion control component 200. The valve 180 is the main switch for delivering fuel gas, which can cut off or divert the combustion gas in the gas pipeline 160; and the first-level solenoid valve 190 can regulate the flow rate and flow velocity of the combustion gas flowing to the combustion control component 200; thereby, it can ensure that the fuel gas is introduced stably and smoothly, while ensuring that the fuel gas is sufficient, so that the baking temperature is high and the combustion is fully and evenly distributed.

[0046] It should be noted that a pressure gauge 410 is provided between the valve 180 and the first-level solenoid valve 190 in the gas pipeline 160. The pressure gauge 410 can detect the ambient pressure in the gas pipeline 160, and then, the flow rate and flow velocity of the combustion gas can be adjusted and controlled according to the data detected by the pressure gauge 410.

This setting greatly saves labor costs and operation time, and makes the combustion gas transportation safe.

[0051] The front combustion tube 130, the middle combustion tube 140 and the rear combustion tube 150 are all spliced ​​pipes 250. Therefore, the length of the spliced ​​pipes 250 can be conveniently set according to the different production requirements of the biscuit baking process, and each spliced ​​pipe 250 is spliced ​​and connected through the air duct ring 260, which not only makes the connection of the spliced ​​pipes 250 stable, but also makes the installation and disassembly of the spliced ​​pipes 250 convenient.

[0052] In some specific embodiments of the present invention, a plurality of combustion tubes 270 are evenly arranged at the front end of the front combustion tube 130, the front end of the middle combustion tube 140 and the front end of the rear combustion tube 150, and the combustion tubes 270 can bake and burn the mold.

In addition, the combustion tube 270 has a stable structure and the distance between the burner 290 and the mold is reasonable, so that the combustion flame is in full contact with the mold surface, so that the biscuits are baked evenly.

[0056] In some specific embodiments of the present invention, two combustion control assemblies 200 are provided, and the combustion control assemblies 200 are respectively communicated with the combustion pipeline mechanisms provided on the upper and lower sides of the mold.

Therefore, the combustion control mechanism can simultaneously supply gas to the two combustion control components 200, ensuring sufficient supply of combustion gas, ensuring sufficient combustion during the baking process and uniform combustion of the mold.

[0058] In some specific embodiments of the present invention, the bellows 110 and the spliced ​​pipe 250 are connected through a connecting assembly 300.

After the gas delivered by the combustion control assembly 200 enters the wind box 110, it is diverted through the diverter pipe 310 and the tee and a joint 320 and flows to the front section combustion tube 130, the middle section combustion tube 140 and the rear section combustion tube 150 respectively. As a result, the gas in the front section combustion tube 130, the middle section combustion tube 140 and the rear section combustion tube 150 is uniform and sufficient, so that the front section combustion tube 130, the middle section combustion tube 140 and the rear section combustion tube 150 can be continuously and fully burned.

The air flap 370 can be adjusted by adjusting the valve core 360 ​​to control the gas flow rate, and then the temperature and duration of baking combustion can be adjusted and controlled, which is suitable for different biscuit production and processing requirements and improves the applicability of baking combustion.

[0062] In addition, a protective cover 380 is provided above the adjusting nut 350 . The protective cover 380 protects the adjusting assembly 340 , effectively prevents accidental contact with the adjusting valve core 360 ​​, and also plays a role in dust prevention.
