微波干燥機

微波是指頻率在300兆赫茲到300千兆赫茲的電磁波。被加熱介質物料中的水分子是極性分子。它在快速變化的高頻電磁場作用下，其極性取向將隨著外電場的變化而變化，造成分子的運動和相互摩擦效應。此時微波場的場能轉化為介質內的熱能，使物料溫度升高，產生熱化和膨化等一系列物化過程而達到微波加熱干燥的目的。

微波干燥機的特點:

微波干燥是一種高效、節能、穩定、可靠、設備簡單、操作方便和新技術。微波干燥機的特點是設備連續生產，只需要用電，不需要其它能源，能快速的將物料干燥，設備占地小，無污染，操作簡單；不需要預熱也沒有在停機后還有能源損耗。人工少，產品質量高。設備*化程度高，是別的設備無法替代的*產品。

Microwave dryer

The purpose of microwave dryer is:

Mainly used for paste food, powder food, granular food, agricultural products, and other products that need to be dried by microwave drying sterilization; microwave dryer can be designed and manufactured according to the different needs of different products.


Heating principle of microwave dryer


Microwave refers to electromagnetic waves with frequencies ranging from 300 MHz to 300000 trillion Hz. The water molecules in the heated medium are polar molecules. Under the fast changing high frequency electromagnetic field, its polar orientation will change with the change of external electric field, resulting in the movement of molecules and mutual friction effect. At this time, the field energy of microwave field can be transformed into heat energy in the medium, which makes the material temperature rise, and produces a series of physical and chemical processes, such as heating and expansion, to achieve the purpose of microwave heating and drying.
