一臺紅棗烘干機設備在烘干紅棗時烘干溫度是如何進行控制的？
紅棗烘(hong)(hong)干(gan)機(ji)設備(bei)是近(jin)些年所(suo)產生的(de)一種(zhong)(zhong)設備(bei)，這(zhe)(zhe)種(zhong)(zhong)設備(bei)是利(li)用外(wai)界(jie)中(zhong)的(de)空氣熱量(liang)來進(jin)(jin)行烘(hong)(hong)干(gan)紅棗的(de)，烘(hong)(hong)干(gan)的(de)過程中(zhong)是采用蒸發器(qi)在外(wai)界(jie)進(jin)(jin)行吸收熱量(liang)，然后(hou)再將這(zhe)(zhe)種(zhong)(zhong)氣體(ti)傳到(dao)(dao)壓(ya)縮機(ji)進(jin)(jin)行壓(ya)縮成(cheng)高溫高壓(ya)的(de)氣體(ti)，壓(ya)縮成(cheng)高溫高壓(ya)的(de)氣體(ti)后(hou)，將這(zhe)(zhe)種(zhong)(zhong)氣體(ti)傳到(dao)(dao)冷凝器(qi)進(jin)(jin)行釋放(fang)出熱量(liang)來給紅棗進(jin)(jin)行烘(hong)(hong)干(gan)，依次這(zhe)(zhe)樣循環就是紅棗烘(hong)(hong)干(gan)機(ji)設備(bei)烘(hong)(hong)干(gan)的(de)原(yuan)理。
使用紅棗烘干機設備烘干紅棗的方法步驟
一(yi)、預熱(re)階(jie)段
剛開式(shi)我(wo)們把紅棗烘干機設備(bei)的(de)溫度(du)調到40-50攝(she)氏(shi)度(du)之間，時(shi)(shi)間為2小時(shi)(shi)，表皮水分蒸發。
二、排濕烘(hong)干
排濕(shi)階段(duan)我們把烘干(gan)機的(de)(de)溫(wen)度升溫(wen)到55攝氏度，時間(jian)為10小(xiao)時，此時的(de)(de)紅棗脫水率為百分之70左右。
三(san)、高溫(wen)烘干
這(zhe)個(ge)階段的烘(hong)干我們要(yao)把溫度升(sheng)溫到(dao)60攝氏度，加(jia)強除 濕，濕度為百分之55，時間為10小(xiao)時
四、高溫排濕
高(gao)溫(wen)(wen)(wen)排濕階(jie)段我(wo)們要均(jun)勻(yun)讓紅棗進行排濕，溫(wen)(wen)(wen)度(du)降(jiang)溫(wen)(wen)(wen)控制在攝(she)氏度(du)55，烘(hong)烤時間為5小時，此時紅棗含水(shui)率低于百分之12。
總結：紅(hong)(hong)(hong)棗烘(hong)(hong)干(gan)機(ji)再在烘(hong)(hong)干(gan)紅(hong)(hong)(hong)棗時(shi)，需要注意的是(shi)如何進(jin)行控(kong)制(zhi)(zhi)烘(hong)(hong)干(gan)機(ji)的溫度，與烘(hong)(hong)干(gan)的時(shi)間，如果控(kong)制(zhi)(zhi)不(bu)(bu)好紅(hong)(hong)(hong)棗烘(hong)(hong)干(gan)機(ji)設備的話，烘(hong)(hong)干(gan)出來的紅(hong)(hong)(hong)棗質(zhi)量(liang)就(jiu)無法進(jin)行保(bao)障(zhang)，或者說是(shi)紅(hong)(hong)(hong)棗烘(hong)(hong)干(gan)機(ji)設備在烘(hong)(hong)干(gan)紅(hong)(hong)(hong)棗時(shi)因為時(shi)間沒有控(kong)制(zhi)(zhi)好，就(jiu)會發生一種情況就(jiu)是(shi)烘(hong)(hong)干(gan)的過程中(zhong)受(shou)熱不(bu)(bu)均勻(yun)，烘(hong)(hong)干(gan)出來的效果不(bu)(bu)好。
