5- fine bagasse separators many particles of bagasse drop from the mills falling through the space between feed plate and feed roller or being extracted from the massecutte by the scrapers or dropping between the trashplate and delivery rollerthe quality of such fine bagasse is very variable, but ganerally amounts to between 1 and 10 gram of dry material per liter of juice. the seperator is an apparatus placed after the mills, serving to screen the mill juices and to the return to an intermadiate carrier the pieces of bagasse recovered 6- defecationhundreds of material have been tried for purification of juice. there are however, only four of which are importantlime which, since the beginnings of sugar manufactures has retained the universal basis defecant the treatment with lime is called defecation7- evaporation and crystallization the massecutte after evaporation discharge from the pan is at high supersaturantion. if it is allowed to stand the sugar still contained in the mother liquor will continue to be deposite as crystal, but this massecutte is very dense and the mother liquor is very viscous. crystallization will soon cease, if the massecutte is left undisturbed, because the layer of mother liquor surrounding the crystals will be rapidly exhausted, and the vicosity of mass will prevent the more distant molecules of sugar from cirulating and coming in contact with the crystals crystallization, then, is a process which consist of mixing the massecutte for a certain time after dropping form the pan, and before passing to the centrifugar, and which ains at completing the formation of cystal and forcing further exhausting of the mother liquor8- storage and drying of sugar the commercial sugar leaving the centrifugal, which is to be dried and packed or sale or export, ganerally has a moisture content of 0,5 - 2% moisture is very detrimental to keeping qualities of the sugar when it exceed a certain limit and particularly when it rises above 1%9 molasses molasses is by product of sugar factory. the true density of molasses is ganerally of the order of 1,4-1,5. it normally contains about 50% of sugar and ohter ingredients but it normally contains fine air bubbles entrained during the fugalling process and also picked up by friction every time the molasses if discharge in a fine stream into a tank
