當(dang)倉庫干(gan)燥(zao)，干(gan)燥(zao)和砰擊時，谷物(wu)(wu)堆的(de)(de)表(biao)面嚴重腐爛。您(nin)可(ke)以(yi)(yi)(yi)組織人力將(jiang)(jiang)冷凝(ning)食(shi)(shi)(shi)品運出倉庫進行(xing)干(gan)燥(zao)或(huo)(huo)烘干(gan)。如果冷凝(ning)范圍已(yi)經很大，應及時傾倒倉庫。它(ta)還具有冷卻和分(fen)(fen)散水(shui)(shui)(shui)分(fen)(fen)的(de)(de)作(zuo)用(yong)。例如，在(zai)2011年冬末，黑龍江土地復墾勝利糧(liang)庫將(jiang)(jiang)儲存6900噸玉米(mi)，并在(zai)鄰近(jin)的(de)(de)倉庫內產生冷凝(ning)擴(kuo)張跡象。倉庫關閉(bi)后，玉米(mi)溫度將(jiang)(jiang)逐(zhu)漸恢(hui)復正常，冷凝(ning)將(jiang)(jiang)得到解(jie)決(jue)，以(yi)(yi)(yi)避(bi)免損(sun)失。 2當(dang)糧(liang)食(shi)(shi)(shi)堆的(de)(de)表(biao)面部分(fen)(fen)露(lu)水(shui)(shui)(shui)凝(ning)結時，當(dang)糧(liang)食(shi)(shi)(shi)堆的(de)(de)表(biao)面部分(fen)(fen)露(lu)水(shui)(shui)(shui)凝(ning)結時，除(chu)了手動或(huo)(huo)谷物(wu)(wu)翻轉機(ji)在(zai)冷凝(ning)現場轉動糧(liang)食(shi)(shi)(shi)表(biao)面外，單管風扇可(ke)以(yi)(yi)(yi)用(yong)于(yu)(yu)通(tong)風處理，吸水(shui)(shui)(shui)劑也(ye)可(ke)用(yong)于(yu)(yu)解(jie)決(jue)問(wen)題。生石灰通(tong)常用(yong)于(yu)(yu)生產中以(yi)(yi)(yi)從谷物(wu)(wu)堆中吸收水(shui)(shui)(shui)。它(ta)也(ye)可(ke)以(yi)(yi)(yi)與其他食(shi)(shi)(shi)品級吸水(shui)(shui)(shui)劑一起(qi)使(shi)(shi)用(yong)。吸水(shui)(shui)(shui)效果明顯，可(ke)重復使(shi)(shi)用(yong)兩到三次(ci)。

單(dan)管(guan)風(feng)(feng)(feng)扇(shan)是可移動的局(ju)部通(tong)(tong)風(feng)(feng)(feng)系統(tong)。工作(zuo)時(shi)(shi)，風(feng)(feng)(feng)扇(shan)用(yong)于通(tong)(tong)過(guo)單(dan)管(guan)空(kong)氣通(tong)(tong)道將(jiang)(jiang)低溫(wen)低濕空(kong)氣壓入谷物堆(dui)中，或者將(jiang)(jiang)谷物堆(dui)中的高溫(wen)高濕空(kong)氣從谷物中抽出樁(zhuang)達到散熱(re)和(he)(he)除濕的目的。方(fang)(fang)便糧(liang)食(shi)的長期安全儲存。特別是在處(chu)(chu)理(li)糧(liang)堆(dui)局(ju)部供熱(re)問題時(shi)(shi)，糧(liang)庫(ku)密封門窗(chuang)生產廠家(jia)，單(dan)管(guan)風(feng)(feng)(feng)機(ji)的通(tong)(tong)風(feng)(feng)(feng)效(xiao)果(guo)顯著。處(chu)(chu)理(li)顆(ke)(ke)粒(li)(li)樁(zhuang)表面(mian)(mian)(mian)大面(mian)(mian)(mian)積結(jie)露時(shi)(shi)，糧(liang)庫(ku)密封門窗(chuang)價格，應(ying)采用(yong)整排單(dan)管(guan)風(feng)(feng)(feng)機(ji)進行(xing)通(tong)(tong)風(feng)(feng)(feng)。采用(yong)壓入式(shi)(shi)通(tong)(tong)風(feng)(feng)(feng)法處(chu)(chu)理(li)顆(ke)(ke)粒(li)(li)樁(zhuang)的淺(qian)層(ceng)結(jie)露，采用(yong)吸(xi)入式(shi)(shi)通(tong)(tong)風(feng)(feng)(feng)法處(chu)(chu)理(li)顆(ke)(ke)粒(li)(li)樁(zhuang)中下層(ceng)局(ju)部結(jie)露。在處(chu)(chu)理(li)之前(qian)，松(song)散顆(ke)(ke)粒(li)(li)表面(mian)(mian)(mian)下方(fang)(fang)30-50cm的顆(ke)(ke)粒(li)(li)層(ceng)，并且(qie)在管(guan)道插入和(he)(he)通(tong)(tong)風(feng)(feng)(feng)時(shi)(shi)使顆(ke)(ke)粒(li)(li)表面(mian)(mian)(mian)平(ping)整以減小氣流(liu)的阻力(li)。通(tong)(tong)風(feng)(feng)(feng)時(shi)(shi)打開所有箱窗(chuang)，以加快(kuai)箱內外(wai)的空(kong)氣對流(liu)。
