Title: Manufacture of lump sugar
IPC: C13B50/02
Filed: 1962-04-30
Abstract: In a process and synchronized apparatus for manufacturing lumps of sugar, moist powdered sugar is pressed into lumps by the horizontal rotating pressing roller 1a of a conventional press 1, Figs. 1 and 2. The lumps are deposited on individual rectangular drying plates 3, carried on a band conveyer 4 travelling beneath the pressing roller. These plates are each formed, along two parallel sides, with two upwardly projecting strips or integral projections, Fig. 4, which facilitate the stacking of one plate on top of another.  The plates, loaded with lumps of sugar, are delivered, by a pusher 6, on to a feeding table 5, which is lowered, by a distance corresponding to the height of a plate, after each delivery, so that a stack of plates, e.g. comprising 20 plates, is formed on the table 5.  The stack is then pushed by a piston (not shown) on to a roller conveyer 7 and the <PICT:0994488/C6-C7/1> <PICT:0994488/C6-C7/2> <PICT:0994488/C6-C7/3> emptied table 5 is moved on to a hoisting device 8, from which a similar table 5a is simultaneously moved to receive another stack of plates from the conveyer 4.  When two or more, e.g. three, such stacks, constituting a batch, are on the conveyer 7, it carries them into an elevator 9, which raises the batch and moves it on to a selected roller conveyer deck 10 of four such superposed conveyer decks in a dryer 11.  The motor driving the elevator 9 is controlled by a deck-selector.  The batch is moved one plate length along the deck 10 and its place is taken by another batch and these operations are repeated until the deck 10 is filled with batches.  The lumps of sugar are dried in a current of hot air circulated, by a fan 13, through a duct 16, a filter 14, a heater 15 and the dryer 11.  Some air is exhausted through an outlet 17 and replaced by air drawn in through an inlet 18 and/or the shaft of an elevator 12, which receives batches, one by one, from the deck 10 and lowers them on to a roller conveyer 19, provided with a device for tipping the stacks and removing the dried lumps of sugar, which are received in a suitable receptacle.  The empty stacks are then transferred, one by one, on to an elevating discharge table 20, from which the empty plates are transferred, one by one, by a chain conveyer 21, a vertical chain elevator 22 and a pusher 23 on to the band conveyer 4 to receive lumps of sugar from the pressing roller.  The dryer 11 and the elevators 9 and 12 are completely enclosed to form a drying unit, into and from which batches are passed through openings provided with piston-operated doors.
