挂面纸包装机包装质量稳定性比较

为明确基于关键技术改进的挂面纸包装机的包装稳定性,满足挂面生产企业对纸包装挂面稳定性和效率的要求,以某面业公司挂面生产线包装车间为取样点,对2组不同机型(编号:HNQ、SDH)各4个机位开展在线挂面纸包装效果测定和分析。结果表明:实施了关键技术改进的HNQ包装机各机位包装挂面即时测定重量与SDH包装机无显著差异,而且机位间差异较小,表明两类设备称重的稳定性较高。与SDH包装机相比,HNQ包装机包装挂面每把的周长变异系数小,捆扎紧度的稳定性更高;SDH的H1、H2、H3机位包装挂面的周长差异较小,紧实度相似;HNQ包装机Q2、Q3、Q4机位包装挂面的周长差异较小,紧实度相似。HNQ包装机包装挂面端面感官效果明显优于SDH包装机。重量、周长变异系数,外观与底角以及端面感官评分可作为纸包装挂面包装效果的主要评价指标。裹卷技术、封尾装置等关键技术和设备的改进,显著地提升了挂面自动化纸包装机包装工艺稳定性及效果。

Study on the packaging quality stability of paper-packaging machines for Chinese dried noodles

To determine the packaging quality stability of paper-packaging machines (HNQ) for Chinese dried noodles based on the key technology improvement, and to meet demands from noodle industries to packaging stability and efficiency, the production lines of a dried noodles manufacturing industry were sampled for investigation. The packaging effects of two kinds of packaging machines (HNQ and SDH) and four same machines in a line were for each kind were tested and analyzed. The results showed that no significant difference in the instant weight of packaged noodles between the SDH packaging machines was found. The differences of coefficient variation (CV%) among four HNQ packaging machines were small, and this indicated the relatively high packaging stability for weighting of the two kinds of packaging machines (HNQ and SDH). In addition, compared to SDH packaging machines, each packaged noodle from HNQ packaging machines displayed smaller coefficient variation (CV%) of perimeter, and this confirmed the HNQ packaging machines with stabled perimeter. For four HNQ packaging machines, dried noodles from HNQ₂, HNQ₃, and HNQ₄ packaging machines had lower perimeter variance and similar tightness, which were similar with those of SDH₁, SDH₂, and SDH₃. The surface sensory evaluation of packaged dried noodles from HNQ packaging machines was obviously better than that of SDH packaging machine. Weight, perimeter, appearance, as well as sensory scores could be used as the main evaluation parameters for packaging results of paper-packaging machines. Improvements such as wrapping techniques and sealing devices have significantly enhanced packaging result and stability of automatic paper-packaging machines for Chinese dried noodles.
