` Due to their dimensions, these driers exhibit manifest themselves in insulicient `utilization of water at` the vbottom of the cylinder eliminates` i `part of the `heat exchanging surface from opera;- tion. It is also knownthat the` effective drying surface of `such cylinders is"V never fully utilized,
, spread uniformly thereon. l l 7. Furthermore, the temperature `range which [may be appliedtofthfe drying surfaces is-limitbidsthe application of high steam pressure Vfor 1 "reasons of safety. i
` `Removal of thejdry material from `the mantle.,` by means of a scraper is likewise difficult, par?` ticularly whenfthe smooth surface islnjured by? 3a the scraping effect ofthe knives.l i`
It `has been foundthatvthesedrawbacks can be `l remedied by shaping the `aforementioned hollow i ,u cylinder intoa drum, having a horizontal axis i whichisshorterthan the vertical diameter `ouf the drum, i; e; the "proportion of vertical `diameter ascertainedthat the inner surface of the drum edfthereto, into and from which tubes-thelheating agent,evenly distributedA over. the entire-circumference,` isintroduced and discharged.` Due ameter and short'rnantle oftheV drum. The outer part of the mzintle of the drum may bebuilt` without regard to theainount of steampressure dissolvedsubstances,are completelyclosedhollow cylinders, the horizontal dimensions of which are disadvantages and difficulties which especiallyr the heating medium'and of the heat` exchangbecause the substances tobe dried cannot be ed, duetothestructure of castiron Whichj formantle can be heated'by means of tubes weld`V applied and yet it will notybe exposed tothe fdangerof warping, since" the inner parts of thedrum such asthe tubes supporting the mantle which donot participate inthe drying process,
"canfbe .given any required stability. Therefore, `materials which are not suitablelor the hither- "to used hollow cylinders, for instance, wrought ironand `refined steels, are preferred in the-pres# u, `entinvention. i 'wlOkof` the. drum" is, usually made of cast iron.` f
Wrought iron,` and refined steels, if worked into` Further advantages become obvious in the prac-tical` use of the new drum driers. Charging of the material to be dried upon a mantle which is so greatly reduced in length proceeds without ..difliculty, `likewise discharging of the dry material.` It is feasible to spread the Wet'rnaterial in a rather thick layer upon `thesurface ofthe .u mantle, thus allowing gentler `treatment of the surface during scraping, since itv is known `that thedry material adheres `theless rigidly `to the ymantle the thicker the layerls in` which it is applied thereto.
The heat exchange is most efficient because of `the veryrrapid velocity of the flowA of steam through the tubes, and due to the reduced thicku `In summary itmay be said that the advantages `of the present invention over the known drum driers reside `in simplifled construction which yields an equal drying effect upon an `essentially Ismaller heating surface. vd'rum drier possessing a surface of 6 square metersequals a cylindrical drier used heretofore,
For instance, my novel which "is directly heated with steam and. which has a drying surface vof.24` square meters. Thenew drier is operative not only fordrying materials by means of aheating medium, as
heat exchanging medium. u u In the accompanying `drawings one embodi-` `mentof mynew drum drier is illustrated by way of example.
Fig. Irepresentsa central transverse vertical section of adrier according `to the invention.
` The drier.consists` of a mantle I, to which the heating system 2 is sprally welded in the form of tubes. The charge and discharge of the heating medium is effected through chambers l prosuggested, .but also for the manufacture of ice u u from water by using, for instance. a cool brineas videdwithin the shaft'3. The chambers arelconnected with the' two ends of the heatingcolls 2 by radially arranged spoke-like tubes 5. Inlet and outlet to and from the chambers 4 is eilocted bv means of connecting tubes 8 and 9, which are tightened by (1o-operation with stuffing boxes 6 in the bore holes 1 of` the shaft 3. The shaft 3 is provided with bearings of the customary construction at point I0.
Figure II is a sectional viewtaken on the line 2--2 of Figure I. In Figure II a device II is to be seen by means of which the material to be dried is spread onto the drum. I2 illustrates a scraping knife by which the dried material is taken off from the drier. of the material to be dried.
