The devices commonly used up to now, which are used to dry sugar, consist of a rotating cylinder equipped with drivers. At that by steam When the axle is heated, caramel formation occurs easily, owing to the fact that sugar adheres to the axle remain; When it falls, this leads to contamination of the sugar and dissolves when the apparatus is mounted, one part of the sugar always becomes blind.

To avoid this caramel formation and bleaching and during drying To bring about a sorting of the sugar according to grain size at the same time, the in The arrangement shown in the drawing is used, which is characterized by the connection of full, zigzag arranged one above the other Shaking plates with sorting shaking sieve underneath, using a heating device for the through the Apparatus drawn in by means of a fan.

The apparatus ("granulator") consists of the shaking bases α α α, which are located opposite one another and made of solid sheet metal (or corrugated iron), which are set in shaking motion by eccentrics χ and tie rods ^ and which are arranged in relation to one another, that the material falling from the higher standing sheet falls onto the sheet below. The latter takes over the further transport of the goods and empties them again onto the metal sheet arranged below.

While the moist sugar is passing the various shaking plates, the sugar is dried by the stream of air passing through the apparatus and heated by the steam coil d, which is constantly sucked out of the apparatus by the exhaustor e. The dried sugar falls from the lowest vibrating plate α onto an inclined vibrating sieve, which is composed of various finely and coarsely perforated sieves ss ^l s ² , and the dried sugar is emptied according to its granularity into the discharge funnel tf t ² , while the largest pieces Sugar get into the drain t ³ .

The steam coil d heats the air entering the granulator through the bottom, which, rising upwards, washes around the shaking plates aa and accelerates the drying of the sugar products located in a flat layer on these plates. The air contaminated with moisture is discharged from the exhaustor through the pipe r.

The sugar is fed in through the pouring funnel g \ the moist sugar is lifted by the elevator f and poured at the top of the apparatus through the ascending pipe m onto the top vibrating plate α.

Find it! thus in addition to the simultaneous sorting of the sugar according to its grain size also the perfectly even drying takes place, without giving the sugar an opportunity Caramel formation and blind is given.

There are no highly heated metal sheets with which the sugar comes into contact can come. Rather, the

Drying with moderately heated air, the temperature of which is kept low enough can.

Another advantage of the apparatus is that the movement of the Sugar on full metal sheets by shaking the same the sticking of the moist Sugar on the trays is avoided and the loosening of any stuck sugar particles takes place automatically by the subsequent sugar lumps.

Claims (1)

Patent claim: Drying and sorting device for sugar, characterized by the connection of zigzag superimposed full metal sheets a, which receive a shaking movement, with shaking sieve Jj ¹ S ² of different mesh sizes arranged underneath and by the arrangement of a steam heating coil under the shaking sieve for those flowing through the apparatus and heated air moved through it by means of exhaustors. For this purpose ι sheet of drawings.
