Nasan Microwave Dryer

Microwave dryer is an electromagnetic radiation dryer to heat the material directly without Intermediate medium, microwave drying is the fastest speed drying technology until now.

Microwave refers to the electromagnetic waves frequency between 300MHz-300GHz, wavelength is between 1mm to 1m. Microwaves usually show penetration, reflection and absorption characteristics. For glass, plastic and porcelain, the microwave will penetrate it without being absorbed. For water and food, it will absorb the microwave and heating itself. For metal material, it will reflect the microwave. Microwave uniform heat up the material inside and outside because of the strong penetrability, will not appear outside dry but inside wet. Body heat source state formation shortens the time of heat conduction and saves a lot of drying time. Microwave drying equipment is effective at once, power adjustable, transmission speed adjustable, no thermal inertia residues, compared with the conventional process equipment to save energy by 50%. Microwaves can fast sterilize under low temperature sterilization, material stored for a long time will not mildew. Due to the fast drying speed microwave drying maximum saves the activity of the materials, nutrition ingredient and the original color.

NV model is vacuum type microwave dryer, it is suited to dry material with lower temperature and vacuum condition, to get the best quality dried product.

NB model is batch type microwave dryer, it is suited to dry material with big size or specific request, this model could mixed with hot air and infrared ray.

NT model is tunnel continue type microwave dryer, it is suited to dry big quantity material with automatic operate. This model dryer machine could be single layer or multiple layers, mixed with hot air or infrared ray.
