Description
Technical field
The utility model is related to environmental technology field, specially a kind of air circulation dress for tunnel microwave dryer
Put.
Background technology
Microwave drying is a kind of new drying mode.When drying, microwave energy directly acts on medium molecule and is converted into heat
Can, make to be heated simultaneously inside and outside medium because microwave has penetration performance, it is not necessary to heat transfer, so firing rate is very fast, it is right
Food of the water content below 30%, rate of drying can shorten hundreds times.Simultaneously regardless of object any shape, due to Jie of object
Matter is inside and outside to be heated simultaneously, and the internal-external temperature difference of material is small, homogeneous heating, will not be produced in conventional heating and scorched outside and underdone inside shape is occurred
Condition, greatly improves dry mass.Microwave drying is different from traditional drying mode, its heat transfer direction and moisture diffusion direction phase
Together.Compared with traditional drying mode, with rate of drying is big, energy-conservation, production efficiency high, uniform drying, clean manufacturing, easily realize
The advantages of Automated condtrol and improve product quality, thus be that dry every field is increasingly taken seriously.Early in last century
The sixties, external application and theory just to microwave drying technology carried out numerous studies, had been got back further in recent decades
Development.The research of China microwave drying technology is started late, and has a certain distance compared with foreign countries, but also achieve it is good into
Achievement, also there is many researchs and application achievements.China's microwave drying technology be used for food industry, chemical engineering of materials, medical industry,
The aspects such as exploitation of mineral resources industry, ceramic industry, lab analysis, the processing of wet natural rubber.
Tunnel microwave dryer is widely used in the drying of the various arbitrary shape materials such as powdery, graininess, bulk, column
Dehydration, this drying means temperature is typically relatively low, and it is 40 DEG C or so to commonly use temperature, therefore can be ensured after dry materials are dried not
The advantages of deformation.Tunnel microwave dryer is that material is heated by microwave, and the moisture that material evaporation goes out passes through dehumidifier again
Pumping can also detach the hot-air in drier and direct from dry purpose is realized while due to dehumidifier pumped moisture
Emit, cause the waste of the energy.
