Referring to the third, seventh and eighth figures, when the baking is performed, the door panel 24 of the base 20 is rotated to cover the inlet 23, and then the heating element 32 of the heating module 30 is energized to generate a temperature rise. The heat energy causes the temperature of the barrier layer 31 and the baking space 33 to increase at the same time, because the barrier layer 31 can be insulated and kept warm, so the temperature in the baking space 33 and the temperature of the barrier layer 31 are maintained, and are not baked. During the process, a sharp temperature change is generated, the quality of the baking can be maintained, and it is not necessary to heat up and replenish the lost temperature, and the power can be reduced. In addition, the barrier layer 31 has a function of absorbing moisture, and the to-be-baked material is heated to generate water. When the drum 41 rotates in the baking space 33, the disturbance plate 411 generates an air disturbance to take out the internal moisture, and then absorbs moisture through the barrier layer 31 to help the water to be discharged of the toast, and the moisture is borrowed. The gas is convected and discharged to the baking space 33. The cold air flows in from the bottom groove 22 and the communication groove 312 at the bottom end of the base body 20. The hot air can be discharged from the positions of the through holes 241 and 26 to make the baking space 33 Air can circulate. The driving unit 42 of the drum module 40 drives the gear set 422 to rotate by the motor 421. The gear set 422 also drives the drum 41 to rotate. When the drum 41 rotates in the accommodating space 21 of the base 20, the inside thereof Smaller fines, such as the silver skin of the coffee beans, fall from the holes in the drum 41 and are concentrated to the lower communication groove 312 and the slot 22, and the retainer 28 at the bottom of the slot 22 produces a collection. In addition, when the drum 41 rolls in the baking space 33, the disturbance plate 411 on the outer side thereof can generate an air disturbance effect, so that the air in the baking space 33 naturally flows and passes through the slot 22 and the communication slot 312. The opening is used for convection of the air, and the through holes 241 and 26 are formed on both sides of the seat body 20. When the cover plates 242 and 261 are opened, the baking condition of the drum 41 in the accommodating space 21 can be observed. The through holes 241 and 26 can also generate an air convection effect. The sampling spoon 271 can be inserted into the sampling port 414 of the drum 41 by the sampling hole 27, and the sampling spoon 271 can obtain the object to be baked inside the drum 41. To confirm the effect of baking.

In the baking device 10 of the present invention, when the drum 41 is removed or installed, only the drum 41 and the bracket 43 need to be moved, the weight of the conveyance can be reduced, and the drum 41 can be taken out, so that the user can fill or take out the drum 41. In addition, the barrier layer 31 of the heating module 30 can produce the effect of moisture absorption and heat insulation. In addition to maintaining the temperature of the baking space 33, it is not necessary to heat for a long time or high power to maintain the internal temperature. In addition to reducing power consumption, energy saving and carbon saving, temperature and humidity maintenance can improve the baking effect and improve the quality of baking. The slot 22 of the base 20 and the agitating plate 411 on the drum 41 can automatically generate air flow during the baking process, and no external power is required for ventilation, which can save power, save energy and protect the environment, and can The baking device of the present invention can be applied to the baking of fruit seeds such as coffee beans, beans such as soybeans, and nut foods such as peanuts by avoiding an excessively large amount of air leakage and maintaining a rapid change in temperature.
