Application of Microwave drying machine for paper products:
Features of microwave paper dryer:
Microwave have strong penetration for cardboard,practice shows that in cardboard production process, microwave drying compared with conventional process,not only fast drying speed,low power consumption,but also greatly improved the product quality.
- Fast drying,cardboard uniform,flat,small change.
- Have strong sterilizing function while in microwave drying process,greatly improved mildew resistance ability.
- Compared with far infrared drying,drying time short two-thirds,electricity consumption save 1/3.
Microwave dring equipment used for drying 3~8cm thick wood,honeycomb corrugated cardboard,cardboard box,paper tube,wood chip,building materials,decorative gypsum board,leather etc.In the natural drying ,deformation,cracking,mildew and rot,deterioration caused material scrap is quite serious.In microwave drying ,wood utilization increase at least 5%,the outward diffusion speed of wood internal water is much larger than surface moisture evaporation speed.Therefore,the natural drying and hot air drying wood surface hardening,and affect the water spread out phenomenon doesn't exist.Microwave drying only takes several minutes to tens of minutes,while wood in the drying process,also kill inside egg and larvae.Under the 2450MHZ microwave energy function,for example wood temeprature is 70~80 celsius degrees,only need 3 minutes can kill all the eggs and larvae.
