NEW PROCESS FOR CLAYING SUGARS* 43 



After defcribing the conftruction and difpofition of the cafes 

 which I propoie, I ftiall now point out the manner in which I 

 ufe them. 



In order to avoid very fatiguing tranfportations, in which Manufacturing 

 much time would be loft, I have eftablifhed a cooler in my P rocefs# 

 fugar-work, into which the boiled fugar is conveyed by a 

 gutter from the battery. Near this cooler I have placed two 

 backs, each of the fame capacity with one of my cafes, and 

 thefe lair, are all of equal dimenfions. 



MANIPULATION. 



I draw off my fugar by two batteries * ; when thefe are The fugar firft 

 joined together in the cooler f, I pour them into one of the cooled in a back, 

 backs where the fugar cryftallizes by cooling. This fugar is 

 ftirred two or three times during the interval, until two other 

 batteries have been poured into the refrigeratory : I then fill 

 up my back, and with a paddle I mix well together the fugar 

 thus collected ; after which I leave it at reft till it acquires the 

 conftftence it is fuffered to aflume, when intended to be ma- 

 nufactured into raw fugar. In the interval other fugar is 

 made, to be poured in the fame manner into the fecond back. 



As foon as the fugar has acquired the before-mentioned con- then put into 

 fiftence, I ufe fmall buckets for conveying it into one of my ^ he . cafes to 

 cafes, which I fill to the height of fix lines below its margin. ' 

 I then leave it till coated, at which period I draw out the 

 pegs from the board, in order that the fyrup may run out. 



On the next and the following days, one of the fides of the eafily examined 

 cafes may be opened to obferve how the drainage goes on ; ? a certa,n \ e 

 but it muft immediately be replaced. This facility, which has 

 the advantage of afcertaining the moft favourable moment for 

 claying the fugar, enables us alfo to afcertain at pleafure the 



* The battery (batterie) is the vefTel in which the boiling of the 

 fugar is terminated, and when two boilings are united in the refri- 

 geratory, it is cultomary in our manufactories to call this procefs 

 drawing off the fugar by tivo batteries (tirer le fucre par deux bat- 

 teries, Venformer far deux batteries}. Thefe two batteries con fti- 

 tute the filling (emplie). The name of battery, which ferves to 

 deiignate this boiler, is given to it becaufe the fugar is beaten with 

 a paddle, or frirrer, whenever it tends to raife itfelf above the fides. 



f This is a large boiler which receives the boiled fugar, and in 

 which it is fuffered to lofe its heat before it is drawn off,
