自六十年代以来,冷冻技术用于食品工业后,技术有了很大的发展,已经历了三次换代。近年来,我国科技工作者研制开发了真空冷冻干燥技术设备,其性能达到国际第三代产品的先进水平。已在山东省的莱阳和郯城建成投产干燥仓60m~2×2和60m~2×3两条生产线,实际达到的真空度、冷阱温度、捕水能力和加热板温度等,均好于设计指标。各辅助系统的设备,运行稳定可靠。冻干产品的形、色、味及复水性都极佳。目前又推出干燥仓100m~2和200m~2的型号,以适应企业的需求。我国的食品真空冻干机,技术含量高,产品市场好,可以满足食品冷冻工业的需求。
Since the 1960s, after the freezing technology was used in the food industry, the technology has undergone great development and has gone through three replacements. In recent years, China’s scientific and technological workers have developed and developed vacuum freeze-drying technology equipment whose performance has reached the advanced level of international third-generation products. Two production lines have been built in Laiyang and Lucheng, Shandong Province, with production lines of 60m~2x2 and 60m~2x3. The actual vacuum degree, cold trap temperature, water catching capacity and heating plate temperature are all better than the design. index. The auxiliary system equipment is stable and reliable. Freeze-dried products are excellent in shape, color, taste and rehydration. At present, dry drying bins of 100m~2 and 200m~2 are also introduced to meet the needs of companies. China’s food vacuum freeze dryer has a high technical content and a good product market to meet the needs of the food freezing industry.
