Study Of Microwave Drying Characteristic And Technology On Wild Rice Stem

In this paper, to explore the best wild rice stem microwave drying process as the goal, studied food to be dry as well as microwave drying technology's some elementary theories, have carried on the single factorial experiment to the wild rice stem microwave drying, has obtained the dry characteristic, has established the wild rice stem microwave drying mathematical model. Carries on three factor orthogonal return revolving combination test to wild rice stem microwave drying, has obtained the regression equation, has obtained the good craft combination after the synthesis optimization. The main contents include:Frist,wild rice stem microwave drying characteristic experimental studies.From change relations and so on moisture content and time, dehydration speed and moisture content as well as power consumption and moisture content, has analyzed the slice thickness, the loading, the microwave firepower to the wild rice stem microwave drying characteristic influence.Second,the wild rice stem microwave drying mathematical model studies.The wild rice stem microwave drying is suitable the Page equation model, according to the wild rice stem microwave drying characteristic empirical data, carries on the fitting using the DPS data processing system, has obtained the wild rice stem microwave drying mathematical model.Third, the wild rice stem microwave drying good craft experimental studies.Take the preliminary unit mass emissive power, the later period unit mass emissive power, the earlier period drying time as the change factors, take the appearance quality, the rehydrate compared to, the unit interval/unit time precipitation rate, the unit power consumption as the target, has designed three factor five level two orthogonal revolving combination tests, has obtained the wild rice stem microwave drying various objective function regression equation, has carried on the goal optimization to various objective function, thus obtains in view of various targets preliminary unit mass emissive power, the later period unit mass emissive power, the earlier period drying time optimal fit.
