干燥技术是工、农、牧业生产中普遍使用的一项技术,通常,除了自然干燥外,大部分采用的是电流的热效应、光的热效应等.这些方法有很多弊端,一方面升温对很多被干燥的物体有破坏性,例如:陶瓷加热由于干燥不均匀容易裂缝;中草药加热易损伤药性。另一方面从加热促进蒸发机理来看,升温增大了水分了运动的能量,使水分子挣脱束缚而跑到空气中去,而被干燥的物体从外到内的温差又抑制了水分子扩散到表面。日本学者浅川勇吉将自来水等液体置于“球——板”电极系统中,当施加直流高压、交流高压时发现有促进蒸发现象。我们在“静电保鲜河套蜜瓜试
Drying technology is commonly used in agriculture, animal husbandry and production of a technology, usually, in addition to natural drying, the majority of the current used by the thermal effects of light thermal effects, etc. These methods have many drawbacks, on the one hand warming a lot of Destroyed objects are destructive, for example: ceramic heating due to uneven drying easy to crack; herbal medicine is easy to damage by heating. On the other hand from the heating mechanism to promote evaporation, heating increases the energy of water movement, the water molecules get out of the shackles and ran to the air, and the temperature difference from the outside to the dried objects and inhibit the diffusion of water molecules To the surface. Japanese scholar Asakawa Yongji tap water and other liquids placed in the “ball - plate” electrode system, when the DC high voltage, AC high pressure was found to promote evaporation.
