Technical advantages of microwave freeze-drying

 Home » Faq
  1. Efficiency advantage

When do freeze-drying operation to materials, we need to supplement sublimation heat and the traditional supplemental methods are mainly three kinds: electric heating, diesel heating, alcohol heating; however, in the vacuum state, there is almost no convection and convection heat transfer, so the traditional heating method only depend on conduction mode to supplement sublimation heat to materials and this process is much time consuming and energy consuming.

Compared with the traditional method of supplementation, microwave heating can not need any media, further more, it can heat the material from inside to outside at the same time and its speed and performance is 4-20 times than the traditional heating methods.

  1. Quality advantage

Treated by  microwave  freeze-drying machine,the materials can in maximum keep its  shape, color, nutrients and aroma and its quality is better than the traditional freeze-drying method.

  1. Cost advantage

As the energy is almost used in materials, the heating efficiency of microwave equipment is very high. The promotion of freeze-drying efficiency would achieve continuous mass production of industrial methods and thereby to further reduce labor costs.
