3. Drying Processes

In the traditional drying process, in order to improve the drying speed, the need to raise the external temperature, increase the temperature gradient, but then easy to produce the material outside the scorched inside the phenomenon of raw. But the use of microwave heating, regardless of the shape of the material, the heat can be uniform penetration and can produce the effect of expansion, conducive to crushing.

Under the action of the microwave, the drying rate of the material tends to be consistent, uniform heating. Moreover, microwave drying technology does not affect the colour, fragrance, taste and tissue structure of the dried materials, the active ingredients are not easy to be decomposed and destroyed. Relevant research institutions are proceeding to use microwave drying instead of traditional drying ovens to solve the traditional drying method to dry Sichuan herbal medicine when prone to uneven drying and other problems.

Microwave equipment supporting facilities less occupy less land, easy to operate, continuous operation, easy to automatic production and enterprise management (can be controlled by PLC programming, adjustable temperature).
