摘　　要：以交联淀粉为成膜主料,添加增塑剂甘油,增强剂海藻酸钠制备交联淀粉膜,研究了其实验室和工业化制膜工艺及其参数。结果表明,交联淀粉膜的实验室制膜工艺和参数为:交联淀粉加水溶解,加热,同时采取框式搅拌,搅拌速度为180r/min,在真空度为0.095MPa下脱气15min,在镀铬钢板上刮板成膜,在50℃下恒温干燥6h,均湿,揭膜,贮存。工业化制膜工艺和参数为:交联淀粉在夹层锅中加水溶解,加热,同时搅拌,搅拌速度为40r/min,在紫铜带上成膜,紫铜带转速为1.0r/min,烘缸中通入蒸汽加热,蒸汽压力为0.20MPa(表压),卷膜,包装,贮存,该工艺已中试成功,可扩大生产。With the main material of filming like cross-linking starch, adding plasticizer like glycerin and increaser like sodium alginate, cross-linking starch film were made.The technology and reference data of laboratory and industrialized manufacture on cross-linking starch film were studied in this article. The results showed the technology and reference data of laboratory manufacture on crosslinking starch film were： dissolving cross- linking starch in water, heating it, meanwhile stirring in the frame way with the speed of 180r/min,degassing 15min under the vacuum of 0.095MPa,scraping to film on the chrome-plating-steel board,then drying it 6h under the constant temperature of 50%, drenching with water evenly, taking off the film and keeping in reserve. The technology and reference data of industrialized manufacture on cross-linking starch film were：dissolving cross- linking starch in water in double layer pot, heating it, meanwhile stirring with the speed of 40r/min,scraping to film on the red copper belt and its speed was 1 r/min,then ventilating water vapor to heat in dryer,with the water vapor pressure of 0.20MPa（surface pressure）, rolling up the film, packaging it and keeping in reserve.This technology has been tested successfully and can be applied in expanding production.
