天然绿葡萄干制干装备研究进展

天然绿葡萄干由无核白葡萄制干而成，其传统制干方法有荫房晾制和人工快速制干法。荫房晾制方法干燥周期长，易受风沙、灰尘和虫蚁的污染。介绍了太阳能热泵组合干燥设备、太阳能集热厢式干燥房、混联式太阳能干燥设备和气体射流干燥试验装置等天然绿葡萄干制干装备的研究进展，以期利用先进的烘干技术和设备，提高绿葡萄干品质和档次，提高产品附加值，推动新疆葡萄业可持续发展。 

Research Review of Crude Green Raisin Dried Equipment

Green raisin is made from seedless white raisin.There are two conventional drying methods include shad house drying and quickly handwork drying.Shade house drying has long drying period，is easily polluted by sand，dust and insert.Combination of solar energy and heat pump drying equipment，solar-thermal van drying room，series-parallel solar energy collector and air-impingement jet dryer were introduced.New drying technics of crude green raisin with short drying time and better quality were obtained.The aim was to improve grape industry in Xinjiang.
