15、、色澤等物性指標(biāo)上不去。在國際市場競爭中處于劣勢，有的甚至售價(jià)僅為國外同種產(chǎn)品的1/3。根據(jù)粗略估計(jì)，我國生產(chǎn)的干燥設(shè)備種類僅為國外30%40%。所謂干燥，泛指從濕物料中除去水分或其他濕分的各種操作。如在日常生活中將潮濕物料置于陽光下曝曬以除去水分，工業(yè)上用硅膠、石灰、濃硫酸等除去空氣、工業(yè)氣體或有機(jī)液體中的水分(見減濕)。在化工生產(chǎn)中，干燥通常指用熱空氣、煙道氣以及紅外線等加熱濕固體物料，使其中所含的水分或溶劑汽化而除去，是一種屬于熱質(zhì)傳遞過程的單元操作。干燥的目的是使物料便于貯存、運(yùn)輸和使用，或滿足進(jìn)一步加工的需要。例如谷物、蔬菜經(jīng)干燥后可長期貯存；合成樹脂干燥后用于加工，可防止塑料制品中

16、出現(xiàn)氣泡或云紋；紙張經(jīng)干燥后便于使用和貯存。干燥操作廣泛應(yīng)用于化工、食品、輕工、紡織、煤炭、農(nóng)林產(chǎn)品加工和建材等各部門。干燥三七采用熱風(fēng)干燥，所謂熱風(fēng)干燥，就是通過風(fēng)機(jī)將熱源周圍的空氣加熱，吹到被加熱物體表面，調(diào)節(jié)熱風(fēng)風(fēng)量和加熱溫度，改善熱風(fēng)干燥的效率。調(diào)節(jié)風(fēng)向使風(fēng)向?qū)Ρ患訜嵛矬w，更有利于干燥。熱風(fēng)風(fēng)速不能低于要求的速度，否則，風(fēng)管表面散熱不佳會燒壞熱風(fēng)加熱器。風(fēng)速也不宜過高，因?yàn)轱L(fēng)循環(huán)過程中會損失一些能量，適當(dāng)選擇風(fēng)機(jī)壓力和風(fēng)量才可達(dá)到最佳干燥效果。在整個(gè)干燥過程中，三七的主要變量是干燥速度和干燥時(shí)間。于是，通過正交設(shè)計(jì)實(shí)驗(yàn)的方法，對不同干燥速度、干燥時(shí)間下的三七進(jìn)行干燥，分別計(jì)數(shù)，通過對比

17、，得到相應(yīng)的參數(shù)。再通過綜合分析，最后得到適宜三七干燥的最優(yōu)參數(shù)組合。在整個(gè)過程中，會用到有限元分析、正交設(shè)計(jì)實(shí)驗(yàn)方法，以及會用到一些有關(guān)的軟件，諸如matlab等。（八）附件：檢索結(jié)果題錄匯總（這一部分不用交）planet, used in some way by at least one out of every seven human beings around the globe. half of the worlds books are written in english, and the majority of international telephone calls are
