Comparative analysis of soybean meal vertical silo and mechanized warehouse
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.
