1. Efficient Conventional vacuum drying equipment uses steam for heating. It requires heating from the inside to the outside. The slow heating requires a large amount of coal, while the double cone rotary vacuum dryer uses electromagnetic wave heating without a heat transfer medium. Heating to the inside of the object, the heating rate is fast, 1 kilowatt can add water at room temperature and vacuum dryer in 3-5 minutes. Consolidation and upgrading technology management is the key to heat to 100 °C, to avoid the above shortcomings, so fast, efficient High drying cycles are greatly reduced and energy consumption is reduced. 2, heating evenly due to heating, the material is heated from the inside to the outside at the same time, the material inside and outside the temperature difference is very small, will not produce the conventional heating in the inconsistent situation of internal and external heating, resulting in a puffing effect, conducive to crush, so that drying The quality has greatly improved. 3, easy to control, easy to continuous production and automation. 4, small size, easy installation and maintenance. 5, the product quality is good, compared with the conventional method, the quality of the processed product has been greatly improved. 6, has the effect of disinfection, sterilization, product safety and health, long shelf life. 7, significant economic benefits.
