渣酒为白酒包装生产线灯检环节挑选出来的各种缺陷品类之一,属于质量中的A类缺陷,是白酒包装工艺中常见的并且顽固的质量问题,不仅会带来返工,而且还会带来包装物料的损耗(瓶盖、酒瓶、酒水),同时,如果流入成品中,还会带来消费者投诉的... 渣酒为白酒包装生产线灯检环节挑选出来的各种缺陷品类之一,属于质量中的A类缺陷,是白酒包装工艺中常见的并且顽固的质量问题,不仅会带来返工,而且还会带来包装物料的损耗(瓶盖、酒瓶、酒水),同时,如果流入成品中,还会带来消费者投诉的风险,因此解决包装工艺过程中渣酒的问题是每个酒厂的包装生产线,特别是高端白酒生产线工艺团队、质量团队、生产团队人员的第一要务。通过生产实践,我们发现,渣酒中杂质(非酒水本身析出物)的主要来源为来料酒瓶以及瓶盖在理盖设备中碰撞产生的杂质,通过优化来料酒瓶清洁度、洗瓶机喷水方式以及理盖机可以有效的降低渣酒率,经过两个阶段的改进工作,平均渣酒率降低了90%。 展开更多

The wind pressure characteristics on a saddle roof at wind direction along the connection of the low points are systematically studied by the wind tunnel test. First, the distributions of the mean and the fluctuating pressures on the saddle roof are provided. Through the wind pressure spectra, the process of generation, growth and break down of the vortex on the leading edge is presented from a microscopic aspect and then the distribution mechanism of the mean and fluctuating pressures along the vulnerable leading edge is explained. By analysis of the wind pressure spectra near the high points, it can be inferred that the body induced turbulence reflects itself as a high-frequency pressure fluctuation. Secondly, the third-and fourth-order statistical moments of the wind pressure are employed to identify the non-Gaussian nature of the pressure time history and to construct an easy tool to localize regions with a non-Gaussian feature. The cause of the non-Gaussian feature is discussed by virtue of the wind pressure spectra. It is concluded that the non-Gaussian feature of the wind pressure originates from the effects of flow separation and body-induced turbulence, and the former effect plays an obvious role. 展开更多

The objective of this paper is to improve the monitoring speed and precision of fractional vegetation cover (fc). It mainly focuses on fc estimation when fcmax and fcmin are not approximately equal to 100% and 0%, respectively due to using remote sensing image with medium or low spatial resolution. Meanwhile, we present a new method of fc estimation based on a random set of fc maximum and minimum values from digital camera (DC) survey data and a di- midiate pixel model. The results show that this is a convenient, efficient and accurate method for fc monitoring, with the maximum error -0.172 and correlation coefficient of 0.974 between DC survey data and the estimated value of the remote sensing model. The remaining DC survey data can be used as verification data for the precision of the fc estimation. In general, the estimation of fc based on DC survey data and a remote sensing model is a brand-new development trend and deserves further extensive utilization. 展开更多
