[0002] Corn kernel flaking and fermentation involves steam cooking and mechanical flaking to break down the corn structure and improve starch digestibility. The fermentation process then optimizes nutrition and palatability, ultimately producing high-quality feed with high digestibility and absorption. A hot air furnace is a high-efficiency thermal energy device that uses fuel combustion to generate heat and heats air into high-temperature hot air through heat exchange for industrial drying, heating, or heating purposes.

[0041] As a technical optimization of this utility model, the filter plate 9 can be disassembled and cleaned by setting the disassembly mechanism 13, thereby improving the quality of subsequent filtration.

[0042] refer to Figure 3 The top of the front of the recycling filter box 6 is provided with a vertical groove 18, and the back of the fixing seat 14 is slidably connected to the inside of the vertical groove 18.

[0043] As a technical optimization of this utility model, the vertical groove 18 enables the fixed seat 14 to slide more smoothly inside the recycling filter box 6, reducing the friction between the fixed seat 14 and the recycling filter box 6 and extending the service life of the fixed seat 14.

[0054] The working principle and usage process of this utility model are as follows: First, the heat and flue gas inside the furnace body assembly 3 drift to the inside of the connecting pipe 7 through the exhaust pipe 4. Then, the delivery pump 10 is started. The input end of the delivery pump 10 draws heat into the inside of the recovery filter box 6 through the heat conduction pipe 11. Then, the filter plate 9 inside the recovery filter box 6 will filter it. Then, it is transported to the inside of the discharge pipe 12 through the heat conduction pipe 11. Then, the heat inside the discharge pipe 12 is discharged into the inside of the furnace body assembly 3 through the output end of the delivery pump 10, achieving the effect of absorbing heat and recycling it. After too many filtrations, the fixed seat 14 is pulled upward. The fixed seat 14 drives the L-shaped plate 15 and the convex plate 16 to move upward. The convex plate 16 drives the locking block 17 to move upward, so that the locking block 17 disengages from the inside of the locking groove 20. Then, the filter plate 9 can be pulled out for cleaning, achieving the effect of cleaning the filter plate 9.

[0055] In summary, this energy-saving hot air furnace changes the traditional phenomenon where heat is wasted when flue gas is discharged. It uses a heat pipe 11 to discharge the filtered heat into the interior of the exhaust pipe 12, and then the heat inside the exhaust pipe 12 is transferred to the interior of the furnace body component 3. This allows the dissipated heat to be recovered and reused, preventing heat loss and increasing the energy efficiency of the hot air furnace.
