PAGE-21-顺流式谷物烘干机设计摘要：国东北粮食产量大，而刚收获的粮食需降水处理后才可储藏，每年因为及时干燥而损失的粮食多大几十万吨，本设计针对这一问题设计一台谷物烘干机，在设计时考虑东北冬季温度、干燥成本、干燥工艺，燃料等问题，并采用CAD软件制图，使之能明确的表达干燥机的整体结构。关键词：粮食储藏；谷物干燥机；CADThedesignofAfloat-likegraindryerAbstract：Ourcountrynortheastgrainyieldisbig，Thegrainjustharvestedneededtheprecipitationtoprocessonlythenmaypreserve，Becauseofpromptdryloseseveryyearthegrainisbigseveralhundredthousandtons，Thisdesigndesignsagraindryerinviewofthisquestion，Whendesignconsidersthenortheastwintertemperature,thedrycost,thedrycraft,questionsandsoonfuel，AndusestheCADsoftwarecharting,enablesittobeclearaboutexpressesthedryertheoverallconstruction.Keywords:grainstorage,graindryer,CAD目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc231094066"摘要PAGEREF_Toc231094066\hIHYPERLINK\l"_Toc231094067"AbstractPAGEREF_Toc231094067\hIIHYPERLINK\l"_Toc231094068"1绪论PAGEREF_Toc231094068\h-1-HYPERLINK\l"_Toc231094069"1.1谷物干燥的现状及发展趋势PAGEREF_Toc231094069\h-1-HYPERLINK\l"_Toc231094070"1.1.1谷物干燥的意义PAGEREF_Toc231094070\h-1-HYPERLINK\l"_Toc231094071"1.1.2谷物的特性及谷物干燥的机理PAGEREF_Toc231094071\h-2-HYPERLINK\l"_Toc231094072"1.2.3影响粮食干燥过程的因素PAGEREF_Toc231094072\h-3-HYPERLINK\l"_Toc231094073"1.2谷物干燥机简介PAGEREF_Toc231094073\h-3-HYPERLINK\l"_Toc231094074"1.2.1对流换热式谷物干燥机PAGEREF_Toc231094074\h-3-HYPERLINK\l"_Toc231094075"1.2.2辐射式干燥机PAGEREF_Toc231094075\h-7-HYPERLINK\l"_Toc231094076"1.2.3导热式干燥机PAGEREF_Toc231094076\h-8-HYPERLINK\l"_Toc231094077"1.2.4批量作业式干燥机PAGEREF_Toc231094077\h-8-HYPERLINK\l"_Toc231094078"1.2.5连续作业方式干燥机PAGEREF_Toc231094078\h-8-HYPERLINK\l"_Toc231094079"1.2.6循环作业式干燥机PAGEREF_Toc231094079\h-9-HYPERLINK\l"_Toc231094080"1.3谷物干燥用的燃料PAGEREF_Toc231094080\h-10-HYPERLINK\l"_Toc231094081"1.3.1燃料的种类和成分PAGEREF_Toc231094081\h-10-HYPERLINK\l"_Toc231094082"1.4谷物干燥用供热设备的种类PAGEREF_Toc231094082\h-11-HYPERLINK\l"_Toc231094083"2.谷物干燥机设计PAGEREF_Toc2
