Description
Technical field
The present invention relates to powder drying field, in particular to a kind of microwave drying system.
Background technology
The drying process of powder body is a common technological process in Inorganic Non-metallic Materials experimentation, traditional at present
Drying meanss have：Natural seasoning, external heat source method, conductive drying method, endogenous pyrogen method, convective drying method etc..And it is traditional at present
Method all has certain defect to varying degrees, and such as prior art commonly uses convective drying to calcium carbonate powder granule
Method, is a kind of method granular solids material being dried with fluidization technology.In fluid bed, granule is dispersed in heat
In air-flow, stir up and down, mixing and collision mutually makes dry materials.Because the aqueous dose rate of calcium carbonate powder granular mass weight is high,
Fluidized bed drying process just can blow afloat with larger wind speed and be easier to lump, often formed false dry it is difficult to granulate.
Therefore, fluid bed drying energy resource consumption in dry run is big and low production efficiency.
And external heat source seasoning is so that the moisture in powder body is steamed by stronger external heat source by distributing higher heat
Send out, but because calcium carbonate powder granular mass water content is high, it is therefore desirable to the high evaporation for a long time of higher temperature just can make carbon
Sour calcium granule obtains drying.
Microwave drying is a kind of new drying mode.When being dried, microwave energy directly acts on medium molecule and is converted into heat
Energy.Make heating simultaneously inside and outside medium it is not necessary to conduction of heat because microwave has penetration performance, so firing rate is very fast, do
Dry taking greatly shortens.Material absorbs temperature after microwave energy changes into heat and raises, and the moisture that material includes is evaporated, dehydration
And drying.Because microwave drying is that material inside and outside is heated simultaneously, the internal-external temperature difference of material is little, homogeneous heating, thus without product
In raw conventional heating, scorched outside and underdone inside situation occurs, so that dry mass is greatly improved.If suitably controlling dewatering speed, right
The structure pine of material just can be allowed when material is dried thin, expanded.Compared to traditional drying mode, microwave drying is capable of thing
The pollution-free and uniform drying of material, can be greatly reduced baking temperature simultaneously, realize safety clean and produce.
But, because the microwave drying time is fast, effect is good, so grasping bad drying time and intensity to a certain extent
Material can be made agglomerating, not expanded and pine is dredged, and is unfavorable for the follow-up use of material.
