Abstract

本实用新型提供葡萄预冷及冷链运输保鲜系统,其包括至少一垛垂直摞放的底部及四周均带有孔眼的保鲜筐,筐内衬打孔袋,袋口与筐口平齐,在筐内填装葡萄时,在最上层葡萄的表面设置保鲜垫,该垫与筐体内四周及底部形成容置葡萄的空间;保鲜垫依序包括面层、保鲜剂层及减震层;保鲜剂层是保鲜剂固定在面层上形成的;减震层固定在保鲜剂层上;减震层材料选自热合无纺布、湿法无纺布等,在该材料上分布贯穿的孔,孔为圆形,孔径为1~10mm,孔间距为5mm~100mm;面层材料选自CPP等。该系统占地面积小,操作简便、人工费低、预冷均匀、SO2药剂释放均匀、果皮不易被漂白、水蒸气不易凝结,可避免预冷及冷链运输过程葡萄品质劣变。
The utility model provides a grape precooling and fresh -keeping system of cold chain transportation, it includes perpendicular pile of bottom of putting of at least one buttress and all has the fresh -keeping basket of perforated all around, the basket inside lining bag that punches, a sack and a basket mouthful parallel and level when loading the grape in the basket, set up fresh -keeping the pad on the surface of the superiors' grape, should fill up with the basket in all around and the bottom form the space of holding grape, the fresh -keeping pad includes surface course, antistaling agent layer and buffer layer according to the preface, the antistaling agent layer is that the antistaling agent is fixed and is formed on the surface course, the buffer layer is fixed on the antistaling agent layer, the buffer layer material is selected from heat seal non -woven fabrics, wet nonwoven fabrics etc. The hole that distributes on this material and run through, and the hole is circular, and the aperture is 1~10mm, and the hole pitch is 5mm~100mm, the surface course material is selected from CPP etc. Area is little in this system, and easy and simple to handle, labour cost is hanged down, the precooling is even, the release of SO2 medicament is even, the peel is difficult for the quilt bleaching, vapor is difficult for condensing, can avoid precooling and the shoddy change of cold chain transportation grape article.
