微波干燥機(jī)的用途:
主要用于膏狀食品、粉狀食品、顆粒狀食品、農(nóng)產(chǎn)品、等其它需要干燥的產(chǎn)品的微波干燥殺菌；微波干燥機(jī)可以根據(jù)不同產(chǎn)品的不同需要來(lái)設(shè)計(jì)制造。
微波干燥機(jī)的加熱原理
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(zhì)物料中的水分子是極性分子。它在快速變化的高頻電磁場(chǎng)作用下，其極性取向?qū)㈦S著外電場(chǎng)的變化而變化，造成分子的運(yùn)動(dòng)和相互摩擦效應(yīng)。此時(shí)微波場(chǎng)的場(chǎng)能轉(zhuǎn)化為介質(zhì)內(nèi)的熱能，使物料溫度升高，產(chǎn)生熱化和膨化等一系列物化過(guò)程而達(dá)到微波加熱干燥的目的。

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.
