糧(liang)食烘(hong)(hong)干(gan)(gan)機(ji)是(shi)指熱(re)風烘(hong)(hong)干(gan)(gan)箱，采用回旋式(shi)加(jia)熱(re)裝置，能在短時(shi)間內(nei)產生大量(liang)的熱(re)風，它(ta)能通(tong)過高(gao)溫處理達到(dao)蟲(chong)卵，解決糧(liang)食干(gan)(gan)燥問(wen)題。順(shun)(shun)逆流、混逆流和(he)順(shun)(shun)混流烘(hong)(hong)干(gan)(gan)機(ji)是(shi)分(fen)別利用了各自的優點(dian)，以達到(dao)高(gao)溫快速烘(hong)(hong)干(gan)(gan)，小(xiao)型(xing)糧(liang)食烘(hong)(hong)干(gan)(gan)機(ji)廠家，提高(gao)烘(hong)(hong)干(gan)(gan)能力(li)，不增加(jia)單位(wei)熱(re)耗，保證(zheng)谷(gu)物品質(zhi)和(he)含水率(lv)均(jun)勻。烘(hong)(hong)干(gan)(gan)箱體(ti)(ti)采用金(jin)屬鋁(lv)內(nei)壁板，硅膠(jiao)棉保溫，波紋彩鋼板或(huo)鋁(lv)合金(jin)外(wai)壁板。箱體(ti)(ti)內(nei)采用數字(zi)化控(kong)制(zhi)和(he)檢測，使(shi)空氣循環和(he)加(jia)濕(shi)，加(jia)溫得(de)到(dao)有效(xiao)控(kong)制(zhi)。
