ACCOillrT!NG OF SUGAR IN'TRODUCED FRO]! MOLASSES SILOS

(This section, which formerly was

a

part of the directions for the

Ex-traction Statement, has been reissued in separate form for the sake of greater convenience. )

(a)

General

\Vhon residues from molasses silos a.re taken into the factory for the recovery of crystallized sugar, take particular care that the accounting is correctly handlod in the figures which appea,r on the reports and that the necessary data and samples are obtained.

The principle of tho method is first, thn.t all sugar introduced must be charged somewhere against the :footory, and secondly, that the factory is allowed to receive the benefit on its extraction of any granulated which it can recover, without being charged with nny of this sugar as introduced in the form of granulated. Since this method does not affect the unknown loss, it may create an incentive to improve tho extraction by sacking (as granulated) sugar which would otherwise remain in. tho forr:i of molasses.

(h) Data Required

(1) The Amount of Residues From Silos Introduced. If the residues are pU!!JP0d, obtain the a.mount from.tho mixor measure~ents and tho actual de~or-mination of the "lbs. por cu. ft.11 _{If they are handled in wheelbarrows,} _r:l!lko

if possible.

(2) ''Polarization of Rosidues''• an average sar.iple .of the residues.

t.ime when it is spun, as such sugar is likely to be high in sulphates and the factory may have to exercise care in its introduction.

(c} Calcul~tions.

(1) "Pounds of Sugar in Residues". Multiply the "Pounds of residues fror.1 silos introduced" by tho "Polarization of residues" and divide by 100.

If the raw sugar is weighed, on additional check on the total amount of sugar introduced, or 1_{tPounds of sugar in residues", can be obtained by adding} together the pounds of sugar in the raw sugar and in the molasses produced from the r.esidues. The amount of sugar ostinated in this manner ma.y noIT.Dally be a little lower than thn.t determined directlv, on account of ~olassos which rem~ins

in pipe linos9 etc. ·

(2} "Pounds of sugar in the ra.w sug?,rtl, Multiply the ."Pounds of raw sugar produced from residues" by t.he "?olarhation' of raw sugar produced froo residues1

t and divido by 100 to obtain this figure.

(3) "Pounds of Grar-uln.tod Sug~P-.rnr.i the Raw Sugar". Mi.iltiply the ''Pounds of sugar in the raw sugar" p.y tho gr·a.I1ula.tod factor corresponding to the ''Apparent purity of the raw sugar prci<luced f'ron residues'' and divide by 100. Use Table 22 for obtaininG the granulated factor.

(4) "Pounds of sugnr in :Molasses Produced FrO!!l R':l.w Sugar", Subtract the "Pounds of granulated sugar r'rom. raw sugar" frro tho "Pounds of sugar in the raw sugar." .•

(5) "Tota~ds of Sugar in Molasses Produced Fl7or.1 Residues". Multiply the "Pounds of i}!olasses produced from residues" by tho "PoJ.arization of tho r.iolasses produced from residues", divide by, 100 and to this add the "Pounds o:f

Sugar in r.iola.sses produced f:ror:i raw sugn,r".

Note: If tho rav, sugar is not weighed calculate the "Pounds of Sugar in the raw f?Ugar", the "Pounds of grnnulated sugar fror:1 the raw suga.ri' the "Pounds of sugar in ~classes produced fror.1 rc,w sugar", and the "Total pounds of sugar in molasses produced· fron residues'' indircc t ly according to the follovving example:

If the apparent purity of the raw sugar is 85.8, the "Pounds of granulated sugnr fron the raw sugar" is 50y000 :x: .7517"' 37,585. l?.0,000 - 37,585 or 12,415 is the "Pounds of sugar in :r.:iole..sses produced from raw sugar", and 150,000
