The invention belongs to the technical field of food processing equipment, and particularly relates to a dual-transmission type steaming and baking device for multi-flavor fresh corn. The device is mainly comprised of a box body, a steam exhausting device, steamer drawers, an oven, a steaming box, a conversion layer, a steam transfer plate, a conversion motor, a steam transfer device, a transmission belt converter and the like. A technical process for steaming and baking the fresh corn by applying the steaming and baking device includes the following steps: (1) loading fresh corn, (2) settingsteaming and baking parameters, (3) boiling the fresh corn with steam, (4) exhausting steam from the oven, and (5) baking the fresh corn. The steaming and baking device is reasonable in main structureand complete in function, overcomes the defects that devices in the prior art are short of steaming functions, uneven in food baking and hard to control baking degree, and can carry out uniform baking after boiling the fresh corn. The obtained baked corn is capable of keeping moisture in grains, and is crisp, tender and tasty in mouth feel, delicious and sweet in taste, suitable for the old and the young. Besides, the device is completely controlled by a circuit controller, realizes automatic processing, and is convenient to use, energy-saving, and environmentally friendly in application.
