1、摘要蓮子為藥、食兩用品種,近年來在醫(yī)藥、保健、食品等方面用量大增。在以蓮子為原料加工干果制品時脫殼作業(yè)是一項十分重要的前處理工序。我國現(xiàn)在蓮子的脫殼都是采用手工操作。勞動強度大。近年來,隨著經(jīng)濟的發(fā)展和人們生活水平的提高,和對食品質(zhì)量要求變高,以往的手工操作遠不能滿足現(xiàn)代水果加工的需求,研制一種新的脫殼機構(gòu)是蓮子加工業(yè)的前景所趨。蓮子脫殼機的一般工作過程為:蓮子的喂入、定位、切削與脫殼、成品與下腳料的分別收集。由于蓮子的外形并非規(guī)則形狀.因此在機械加工時,采用蓮子的外形進行定位、夾持,不能保證蓮子核的中心線刀具的中心線重合,定位會出現(xiàn)偏差,增加了蓮子的破碎率和脫殼的不凈率。通過對部分蓮子品種
2、的物理結(jié)構(gòu)研究,設(shè)計導(dǎo)向機構(gòu)定位方式,保證蓮子喂入時的定位精度。針對當前蓮子脫殼機存在的問題,綜合各類水果脫殼機優(yōu)點,設(shè)計出了經(jīng)濟型的蓮子脫殼機,主要包括:送料機構(gòu)、輸送機構(gòu)、彈性支撐機構(gòu)、刀具移動機構(gòu),各機構(gòu)動作協(xié)調(diào),脫殼率高,對實現(xiàn)我國脫殼自動化有深遠的意義。關(guān)鍵詞:蓮子、彈性支撐、自動化、脫殼機ABSTRACTInrecentyearsLotusseed,inmedicine,healthcare,asfoodconsumptionsoarformedicine,foodandvarieties.Inhawthornasrawmaterialprocessingbeverages,ca
