Microwave drying equipment has a unique advantage to dry foam cotton and non-latex sponge. There are thousands of hundreds of air holes inside foam cotton so traditional hot air dryer hardly heat and dehydrate internal moisture. But microwave drying foam is different from traditional heat because microwave heating is relying on the microwave high-frequency electromagnetic wave which excites slug internal water high-speed friction heat between the water molecules, which reduce heat transfer stage as well as accelerate sponge inside water rapidly vaporized and steam hole open, make foam internal moisture rapidly evaporation. On the other hand, microwave drying temperature is relative lower which does not destroy foam properties, Foam microwave drying equipment has a sterilization effect to assure the products clean.

We combine microwave drying with hot air which can maximize the drying efficiency. It successfully addresses the issues of hot air drying, and got a widely application of the other rapid drying of sponge products such as foam cotton, sponge, polyurethane(PU) cotton, fix cotton shape, the latex, rubber, cotton, fire-proof cotton, sound insulation cotton etc. The quality of the microwave dried foam products is good, no deformation, keeping the primary color, bacteriostatic, health care, no vibration, no noise and good elasticity features etc. At present, it has been favored by the cosmetics industry so the product market is huge.
