PROCESS OF COOLING AND DRYING SUGAR.
SPECIFICATION'forming part of Letters Patent No. 296,042, dated April 1, 1884:.
Application filed November 6, 1883. No model.)
GEORGE DINKEL, of Jersey City, New Jersey,
have invented a Process of Cooling and Drying Sugar, of which the following is a specification.
As soft sugar, when discharged from the centrifugal machine in which it is drained, is
frequently warm, it is desirable'to cool it be fore packing it, and this has been done by causing it to fall upon a revolving scatteringwheel, by which the sugar was scattered, and
in connection with which a cooling effect was produced by a current of air established by the rotation of the wheel or otherwise, and directed against the scattered sugar.
Itis the object of our invention to more effectually separate the particles of sugar from each other, and to more thoroughly cool and dry them. To this end we subject the sugar to a process analogous to atomization by di recting upon a column of falling sugar a powerful blast of air drawn from a comparatively cool source, whereby the particles of sugar are violently separated from each other and projected in a prescribed direction and cooled and dried. be repeated, if the sugar operated upon is either unusually warm or excessively moist.
The accompanying drawing, representing apparatus of simple character containing the features essential to the employment of our process, is as follows:
The figure is a vertical section representing portions of several floors of a building, showing the atomizer and part of a vertical pipe or chute for conducting sugar to the atomizer, also showing a bin for receiving the atomized sugar, provided with an outlet at the bottom,
through which the sugar may fallto a lower floor through a pipe or chute, whichmay also.
be provided with an atomizer for repeating the atomizing and cooling operation, if necessary.
In practicing our process the sugar, after being drained in the centrifugal machine, is' conducted to the vertical spout or pipe A, down which it falls by its own gravity into This operation may, if necessary,
the horizontal bend a at the lower end. of the pipe A, the mouth a of which constitutes the discharge-opening out of which the sugar is violently driven by a strong blast of air forced through the air-pipe B by the blower B, and directed into the bend a by the nozzle b.
If the atmosphere of the room in which the operation is performed is too high, the blower B may be provided with a supply-pipe, B, leading from another room or chamber, the air of which is of the desired temperature.
It is desirable that the blast of air directed into the bend a shall have great force, and we have found that with a fourteeninch nozzle the necessary force can be imparted by a thirtythe paths indicated by the diverging dotted lines-O.
It will of course be understood that an inclined chute may be substituted for the vertical pipe A, and that the. nozzle 6 may be inserted into, the lower end of the chute, which may be bent horizontally or otherwise.
The air-blast nozzle a and means for directing the sugar downward to a point in front of the nozzle to constitute what, for convenience, we call our atomizen The sugar, having been projected from the atomizer, falls by its own gravity into the collecting-bin D, the bottom (1 of which is of the usual inverted pyramiwhich the sugar is discharged from the collecting-bin. If the sugar operated upon is excessively warm or moist, the atomizing, cooling, and drying operation may be repeated. For convenience of repeating the operation, we arrange a second atomizer on the floor beneath the collecting-bin D, so that the sugar discharged through the outlet d will fall into the chute E and be conductedto the horizontal bend e, in which is inserted the nozzle f of another air blast pipe, F, connected with the blower F; sugar falls into the bin G, the bottom of which is inclined toward the outlet 9, through which the sugar is discharged from the bin G into the packing-room H. By this mode of treatment the particles of sugar are thoroughly cooled and dried, and the sugar may be at once packed away in barrels without the liability of falling off in color which exists when the sugar is packed in barrels While warm.
It will be seen that the powerful blast of air which We employ performs the mechanical function of scattering the sugar, and so separates the particles of sugar from each other as to fully expose them to direct contact with the air, thus cooling them by. convection, and also evaporating the moisture from them.
Fromthe second atomizer the WVe claim as our invention The process of cooling and drying soft su- 2o gar herein described,which consists in so guiding a moving mass of such sugar as to direct it into or near the mouth of a nozzle, from which issues a strong blast of suitably cool air,which performs the mechanical function of separating the particles of sugar from each other and scattering them, and thus fully exposing them to direct contact with the cool air, whereby such air carries off their heat and absorbs the moisture from them, and thus cools and dries o them.
