银条的冻干工艺研究

银条是一种独产洛阳的特色蔬菜,清脆爽口,味道独特,但保存周期极短。本文拟探索一种新的银条深加工技术,从而扩大其销售市场,甚至打入国际市场。采用真空冷冻这种新型干燥方法对银条进行深加工,测定了银条的冻干特性,为寻求较优工艺参数,主要就真空度与板温对冻干工艺的影响进行了研究。

Study on Vacuum Freeze-drying Technology of Manyflower Betony

The Manyflower Betony is a kind of vegetable only growing in Luo Yang, and its taste is so special and delicious,but it is very difficult to storage. In this paper, a new deep-processing method was explored. The vacuum freeze-drying technologywas introduced into the field of Manyflower Betony deep-processing, and the freeze-drying characteristics were measure. In orderto find the best technics parameter, the research on effect of vacuum degree and heat-board temperature to drying process wasdone.
