Since most companies changed or are changing from solvent borne to low VOC water borne coating in wood furniture or relative wood material, the new drying and curing techniques have been developed. Microwave drying technology is the most popular drying solution in the world. The goal of the technology is to improve drying speed and to cure coatings in an effective way.

Microwave drying is a technique, which enhances drying starting from both center and surface. By irradiation with microwaves, the water molecules in the substrate absorb energy and convert this into heat. Due to the generated heat, the coating is able to dry

One of the main advantages of this drying technique is its fastness: a few minutes are needed for water evaporation. Tunnel microwave could dry a large scale of wood in a short time, the speed is about O. 002m / s-0. 003m / s speed heading.. In addition, microwave uniformly heat up the wood to achieve a good quality (no blisters)

Microwave tunnel dryer could uniformly and fast dry the water borne wood material.
