国外粮食冷藏的研究,主要从选试廉价的隔热材料,研制适合粮食冷藏的制冷装置和研究冷藏技术三方面突破.日本的聚苯乙烯泡沫塑料作隔热材料试验成功,使低温仓迅速发展起来,1976年达200余万吨仓容,占稻米总贮量的15-20%,糙米总贮量的70%.西德60年代初研究出“格拉里弗里高”方法和相应的设备,是冷藏技术发展的重要标志.1962年就有600台装置,处理量达200多万吨,1964年到1970年还出口了500多台设备到22个国家和地区.目前瑞典的韦布尔公司在设计、
The researches on foreign food refrigeration have mainly made breakthroughs from the selection of cheap thermal insulation materials, the development of refrigeration equipment suitable for food refrigeration and the research of refrigeration technology. The successful test of polystyrene foam in Japan as insulation material has led to the rapid development of low temperature storage In 1976, more than 200 million tons of storage capacity accounted for 15-20% of the total storage capacity of rice and 70% of the total storage capacity of brown rice. In the early 1960s, West Germany developed the “Gravolligao” method and corresponding equipment, Is an important symbol of the development of refrigeration technology in 1962 there are 600 installations, handling capacity of over 200 million tons, from 1964 to 1970 also exported more than 500 units to 22 countries and regions. At present, Sweden’s Weibull company design,
