Cashew has high economic values. Almost all the part of this plant are useful. udHowever, the chasew nut is the most important part and the cashew apples is just eaten or udused for syrup. The extraction of tannin from cashew apples can increase the economic value udof cashew apples.The objectives of this research were obtained tannin and to seek the udprocess and operation condition of extraction of tannin from cashew apples. The experiment udwas carried out in a stirred reactor equipped with condenser and mantel heater.Cashew apples udwas in slab form. 250 ml aceton and 60 gram chasew apples add to the ractor. Samples was uddrawn at ceratin times and the tannin concentration was measured by gravimetriv method udThe results showed that increasing extraction temperature and stirrer velocity caused udincrease the tranfer mass(Kc) and diffusivity (De) coefficients . The value of Kc and De are udfrom 0.2322 gr / cmud2ud.min until 1.2678 gr /cmud2ud.min and from 0.031 cmud2ud/min until 0.079 cmud2ud/min udfor the range of stirrer velocity 500 - 800 rpm. The value of Kc and De are from 3.305 gr / udcmud2ud.min until 8.021 gr /cmud2ud.min and from 0.408999 cmud2ud/min until 0.6678 cmud2ud/min for udextraction temperature range 35 ud0udC until 50 ud0udC. ud udKeywords : extract, tannin, cashewapple
