Since the baking zone 13 is exposed to microwave radiation, conventional means of transporting the heated product 10 through the belt is not preferable, since the belt is mostly a soft plastic product, and it is easy to age or decompose some harmful substances under microwave radiation, which may cause damage to the quality of the heated product 10. The movement of the heated product 10 is accomplished in the present invention by moving the power roller 211 from the side.

The third motor 218 is responsible for transporting the heated product 10 from the toasting zone 13 to the second guard zone 14 and from the second guard zone 14 to the feeding zone 15. Three motors are arranged, three driving synchronous pulleys 213 and three tensioning wheels 215 are also arranged in the same way, and the number of the tensioning wheels 215 and the driving synchronous pulleys 213 is equal to that of the motors. And the driving timing pulley 213 is electrically connected to the motor. The corresponding driven pulley 214, the driving synchronous pulley 213 and the tensioning pulley 215 are all connected through belts. When the motor rotates, the driving synchronous pulley 213 drives the belt to rotate, the belt drives the driven pulley 214 and the tensioning pulley 215 to rotate, and the driven pulley 214 drives the power roller 211 to be connected. This effects movement of the heated product 10. The idler pulley 216 is arranged at the same time to limit the position of the belt, the idler pulley 216 is arranged between the two driven pulleys 214 and above the driven pulleys 214, so that the belt can be just pressed, the belt is prevented from being taken away, the normal running of the belt is ensured, and the driving stability is improved

When the screw rod 317 of the linear stepper motor 313 rotates, the screw rod 317 is fixedly connected with the door plate fixing plate 315 through the ball nut 318, so that the screw rod 317 drives the lifting door plate 316 to lift along the track, and the lifting door is opened. When the screw rod 317 rotates downwards, the lifting door plate 316 is driven to move downwards along the track, that is, the lifting door is closed. In order to prevent the lifting door from rising beyond the limit, a limit switch 312 is fixed to the material inlet/outlet sealing plate 311, so that the lifting height of the lifting door can be controlled.
