The front and the back of the heating chamber are equipped with a movable microwave anti-leakage section. Fixed spacing array metal The force constitutes the microwave loop matching cycle: the load reduces the microwave leakage value. In the small continuous microwave hot air blower of the present invention, the instant noodles are heated and dried at the same belt speed and microwave output power, and 9 round instant noodles with weight + 5 are used. In the body, put the surface of the nine samples into an array of η and the temperature change at the center of the three faces of the second column in the middle of the process as a reference for the process. 'Insert 3 sets of light with a length of 1 〇m. The temperature of the center of the process face is recorded by a computer system. When the face body passes through the exit of the microwave leakage prevention section at the end of the heating cavity, the FT τ loss is derived from the PLIR infrared thermal imaging system (Thermo Vision).
