Study And Analysis On The Larger Scale Metal Omponential Controlled Atmosphere Storage Of Surrounding Protection Structure

Controlled atmosphere storage technology is one of the best efficiently postharvest storage technology in the world. Relatively poor in the economy and natural resource, the metal componential controlled atmosphere storage always set a minute pace in our country because that the research concentrates on the combination of science, security and practice. In recent years, the analysis and application of the key segments of atmosphere control storage mainly depends on the foreign products, although the government has paid more attentions on constructing the controlled atmosphere storage of more than ten thousand ton. In order to obtain the best benefits from the storage and process of fruits and vegetables, it is important to construct the metal componential controlled atmosphere storage of large scale.The paper take the example of an controlled atmosphere storage of thirth thousand ton and pay more attention on the key segments by summing up all the achievements about controlled atmosphere storage at home and abroad and combining the practice in the construction the controlled atmosphere storage. In addition, practical research work was applied in the industrial produce, engineering construction and design.The research indicates: Through carries on the decomposition test to the large-scale metal assembly type gas adjustment storehouse surrounding protection system construction organization, discovers its crucial control injury spot, strengthened its whole heat insulation performance and the safe consolidated performance; Unifies German and Japan's metal nature test standard, discovers the insufficiency of domestically produced product strengthens the system production of the domestically produced gas adjustment industry Systematically calculate the surrounding protection structure heat insulation , establishes the most suitable design system, reduces the cold loss of the surrounding protection structure Compares the overseas gas tight test, discovers disparity of the domestic gas adjustment project installment.
