This creation is a kind of circulation deterioration device of tealeaves, mainly be the blow zones formed within the enclosed space with a fan and air-conditioning device composition air distribution area be separately positioned on wither frame this one stand area both ends, the epidemic disaster in Cu Ling air distribution area is uniformly mixed Hou in advance, allow the tealeaves to wither on frame during withering by forward or counter blow is blown and comforted by the forward and reverse air blowing function of blow zones again, more evenly with sharp tea leaf withering process.本創作係一種茶葉之循環萎凋裝置,主要係在封閉空間中以一風扇組成的送風區及空調裝置組成的配風區分別設置在萎凋架此一靜置區的兩端,促令配風區的溫、溼度先行混合均勻後,再由送風區的正、反向送風功能讓萎凋架上的茶葉在萎凋過程中受到順向或逆向風的吹撫,以利茶葉萎凋過程更均勻者。
