Technical Field

[0001] The utility model belongs to the technical field of drying equipment and relates to a parallel double-body vibration baking tank. Background Art

[0002] Nuts, preserved fruits, and dried vegetables are popular leisure foods. After these ingredients have undergone preliminary processing, such as cleaning, pickling, and mixing, they still need to go through the most important step, which is drying them in a dryer.

After that, the hot air enters the hot air chamber in the second outer shell from the second air inlet at the lower end of the second outer shell to bake in the drying chamber. The hot exhaust gas discharged from the second outer shell passes through the third reversing valve 27 and the second hot air reversing pipe 24 through the second return air port and flows to the first hot air blower 21. The first hot air blower 21 uses the waste heat to bake the first baking pool. It should be noted that when the second reversing valve is opened, the inlet of the second hot air reversing pipe close to the second baking pool is closed to prevent backflow. At the same time, when the second baking pool is baking, the first baking pool cover 31 and the baking pool ventilation window 32 are at the upper end of the second baking pool, and the first baking pool cover 31 and the baking pool ventilation window 32 are tightly covered. The first baking pool does not need to cover the first baking pool cover 31 and the baking pool ventilation window, and the exhaust gas is directly vented. The two pools are used alternately.
