Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
It is dried and refers to utilize heat energy or additive method to be removed by the moisture vaporization in wet stock, thus obtain dry
The operating process of dry article, dried material stability is of a relatively high, it is simple to the process of subsequent handling,
Such as, pulverize, store or transport etc..Owing to the type of material is varied, its form and physical property are the most each
The most different, thus for adapting to the dry demand of different material, need to use different drying meanss that it is entered
Row is dried.
At present, classifying according to the temperature range that dried material is suitably dried, conventional heat pump drying divides
For cold drying (being typically for air temperature ＜ 40 DEG C), middle temperature is dried (ventilation temperature 50～70 DEG C) and high temperature
It is dried (ventilation temperature >=70 DEG C).The method of dry materials has refrigeration be dried (cold drying) and heat dry
Dry (high temperature drying) two ways.
Present stage, existing material drying system, including interconnective compressor, cross valve, indoor
