閉式循環噴霧干燥機產品描述

       有機溶劑噴霧干燥機是有機溶劑類料漿干燥的專用設備。該機組是由氮氣(或其他惰性氣體)作為干燥循環氣體,干燥過程物料可以防止氧化、同時有機溶劑可以回收。閉式循環噴霧干燥機一般用于(yu)乙(yi)醇、丙酮、己烷等(deng)有機(ji)溶劑類制備料漿的(de)粉體干(gan)燥,設(she)備采用防爆(bao)設(she)計,干(gan)燥過程安全(quan)環(huan)保。

        氮氣循環適用于(yu)干(gan)燥(zao)過程(cheng)要防止氧化,干(gan)燥(zao)后粉(fen)(fen)體一致性要求高。如醫(yi)藥、化工、食品(pin)、鋰電材料等行(xing)業粉(fen)(fen)體。通過離心(xin)噴霧可得(de)(de)到(dao)平均粒徑10-100μm的粉(fen)(fen)體。當然整個(ge)干(gan)燥(zao)過程(cheng)是在氮氣保(bao)護下完成的,有機溶劑可以同時得(de)(de)到(dao)回收。
