Abstract: This study is to find the regular pattern of drying edible mushrooms by orthogonal design to get the best drying technology and its parameters. From the crossing examination, it proved that the given drying technology and its parameters are excellent and reliable.By botn the data from above test and the re-softing method the study successfully solved the problem of the brittleness of flat mushroom and phoenix-tail mushroom after drying as usually happened.That means this study systematically filled up the technology drying mushrooms too. All the data either from single factor test or from synthetic test are exccllent and highly reliable.The testing method of this paper is also applicable to the study of drying all agricultural products.
