Recently, many companies knock themselves out to reduce logistics costs. However, they have reached the limit on cost reducing by improving the manufacturing process. In addition, Customers are growing more and more particular about the quality. Also the firms, which provide foods & beverages manufacturer with vacant receptacles and bottles, make zealous efforts to save costs. They have tried to seek for the resolution by own investment and improving system, but they haven't found certainly substitutions. In this study, we analyze problems of the vacant receptacles manufacturers and present introduction of pool system by standardization of Packing Resource. This PPS(Packing resource Pool System) will enable to reduce logistics cost that is challenge for the receptacles & bottles manufacturers, be helpful reducing environmental disruption which are the pollution of alien substances, wasted paper sheets because the system cleans retrieved Packing resources and reuses them.

This work is to study the variations of adsorption characteristics of binary vapor according to packing system of double-layer bed by fixed bed experiment. Breakthrough curves of single and binary vapor composed of acetone and benzene on single-layer and double-layer adsorption bed composed of activated carbon (AC) and silica-aluminar (SA) were compared. Adsorptions of binary vapor on double-layer bed were influenced by the differences of surface area between adsorbents as well as the polarity difference between adsorbent and adsorbate. The roll-up phenomenon of acetone vapor was happened by replacement with competing adsorption between acetone vapor and benzene vapor on AC bed, but it was not happened on SA bed because acetone vapor and benzene vapor had less difference in affinity with SA bed. The breakthrough times of acetone vapor and benzene vapor on AC/SA double-layer bed were three times and 1.4 times larger respectively than on SA/AC double-layer bed, the differences of breakthrough times were relatively larger than the equilibrium adsorption capacities according to packing system of double-layer bed.

Packing house is the regional center in which packing, sorting, storage, and selling of harvested fruits are taken care of all together. It is located at the producing centers, and commercializes their apples. Apple grading policies of chief producing centers should concentrate on enhancing functions and roles of its local packing house. Consequently new packing house policies for enacting individual grading standards at national and local levels should be developed. This study is to develop Korea packing house on the basis of field survey in New York State. Increasing the utilization of packing house is the main key to the success of apple grading project. Therefore, effective arrangement and utilization of sorting facilities should be evaluated and new system which enables apple farms, local cooperatives, and corporations to joint-utilize packing house must to be established.
