大豆粕立筒仓与机械化房式仓的对比分析Comparative analysis of soybean meal vertical silo and mechanized warehouse

Abstract

旨在为大豆加工厂仓型选择提供参考，以仓容1.5万t的3 000 t/d的大豆加工厂为研究案例，对比分析了大豆粕混凝土立筒仓与机械化房式仓的进出仓工艺和设备，结合国内部分工厂的实际建设和运营数据，总结分析了两种仓型的占地面积、仓容利用率及投资运营费用等。结果表明，相较于混凝土立筒仓结合出仓机方案，机械化房式仓结合强力出仓机方案在控制大豆粕水分含量和存储风险方面具有一定优势，且每年能够节约26.56%的用电成本。以10年的运营期为计算基准，机械化房式仓结合强力出仓机的方案可降低46.2%（对应2 430万元）的费用现值。综上，机械化房式仓结合强力出仓机方案具有投资低、仓容利用率高、运行成本低、维修费用少、维修便利等优点，且物料分级少，品质有保障，可作为投资者的选项。In order to provide reference for the selection of warehouse types for soybean oil processing plants, taking a 3 000 t/d soybean processing plant with a storage capacity of 15 000 t as a case study, the process and equipment of soybean meal concrete vertical silo and mechanized warehouse were compared and analyzed, the floor area, warehouse capacity utilization rate and investment and operation expenses of the two warehouse types were summarized and analyzed based on the actual construction and operation data of some plants in China. The results showed that compared with the concrete vertical silo combined with reclaimer, the mechanized warehouse combined with powerful reclaimer had certain advantages in controlling the moisture content and storage risk of soybean meal, and could save 26.56% of the electricity cost per year. Based on the 10-year operation period, the solution of mechanized warehouse combined with powerful reclaimer could reduce the present value of expenses by 46.2% (corresponding to 24.3 million yuan). To sum up, the solution of mechanized warehouse combined with the powerful reclaimer has the advantages of low investment, high warehouse capacity utilization rate, low operating cost, less maintenance cost, convenient maintenance, etc. ， and less material classification, quality assurance, and it can be used as an option for investors.
