Embodiment 1
[0017] Embodiment 1, a microwave generator for soft packaging drying, the container material is made of stainless steel, the resonant cavity is made of anti-rust aluminum, the surface of the anti-rust aluminum is polished, anodized, and the microwave frequency is 2450±50MHz, and the continuous wave output power is 20KW. 7×10 -5 Watts / cubic meter, hot-pressed, infiltrated with steam, the color turns white and loses transparency. The flexible packaging is irradiated with microwave energy for 2 minutes, and then air-cooled after taking it out to restore the best transparency.
Embodiment 2
[0018] Embodiment 2. In the above embodiment, the power density is 8×10 -5 Watts / cubic meter, hot-pressed, infiltrated with steam, the color turns white and loses transparency. The flexible packaging is irradiated with microwave energy for 1 minute, and then air-cooled after taking it out to restore the best transparency.
Embodiment 3
[0019] Embodiment three, in embodiment one, adopt power density to be 1×10 -5 Watts / cubic meter, hot-pressed, infiltrated with steam, the color turns white and loses transparency. The flexible packaging is irradiated with microwave energy for 8 minutes, and then air-cooled after taking it out to restore the best transparency.
