Persian Abstract Investigation and Measurement of Important Components in Dust and Three Kinds of Common Waste in Tea Factory

Every year lots of waste will produce in factories from black tea. These waste will remain unusable or through away but only little amount will be used in industry. In this survey, important components of tea dust and three kinds common tea wastes was studied from 1382 to 1383. Four compounds (caffeine, protein, fiber and fluor) were extracted and measured separately from four samples of wastes (dust, fluff, footstalk and stalk) as experimental component. In three periods of plucking (spring, summery and autumn) from two kinds of arrangement (from curve and flat bushes). The experiment were conducted in four experimental components with replications and were analyzed with Duncan method. The results indicated that effects all of wastes, plucking periods and two kinds of arrangement (except effect of that on amount of caffeine) were significant on caffeine, protein, fiber and fluor whereas maximum amounts of caffeine, fluor and protein in dust but maximum amounts of fiber was in stalk and Effect of plucking period indicated maximum amount of fluor and caffeine in summer plucking and maximum amount of fiber and protein in autumn plucking and effect of plots indicated maximum amount of fiber in flat plot and maximum amount of fluor and protein in curve plot.
