8、問(wèn)題:①工業(yè)化生產(chǎn)將利用智能化控制設(shè)備對(duì)米粉老化過(guò)程的參數(shù)進(jìn)行嚴(yán)格的控制,摒棄了傳統(tǒng)經(jīng)驗(yàn)化生產(chǎn)方式的弊端,因此需要探索米粉老化過(guò)程中準(zhǔn)確的參數(shù)數(shù)據(jù);②在干米粉的老化過(guò)程中要求米粉的水分穩(wěn)定,否則將會(huì)使生產(chǎn)出來(lái)的米粉出現(xiàn)復(fù)水能力差、韌性較差、蒸煮損失多等一系列品質(zhì)問(wèn)題。本文針對(duì)以上問(wèn)題,設(shè)計(jì)
