FEED DRIER.
Patented N0v.15,1881.
` WWW vas UNrrEn STATES PATENT OFFICE.
EDlVIN ROAT, OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-HALF TO HARRY HAMLIN,
OF SAME PLACE.
FEED-DRIER.
SPECIFICATION forming part of Letters Patent Application filed June 8, 1881.
To all whom it may concern Beit known that I, EDWIN ROAT, a citizen of the United States, residing at Buffalo,in the county of Erie and State of New York, have invented certain new and useful Improvements in Feed-Driers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to apparatus for drying not only what is known among maltsters, distillers, and starch and grape-sugar manufacturers as feed, but also solid grain, cornmeal,&c.
A cylinder provided with longitudinal buckets has before been used for drying feed, Ste., in connection with a single hot-air flue, upon which it revolves. A similar revolving cylinder, with steam-drum secured in the interior andrevolvin g withit, has alsobefore been used. A system of steam-pipes with buckets attached to the outer pipes has also been revolved-inside of a stationary cylinder for the same purpose. The above devices have failed to dry the feed, &c., in a complete and satisfactory manner.
In carrying out my invent-ion I have taken the cylinder withlongitudinal buckets and provided it with a system of parallelsteam-pipes, connected at their ends with hollow drums or heads, and have placed these pipes at such a distance from the interior surface of the cylinder or from the edge of the buckets as to allow quite a fall for the feed before striking the heated pipes, thereby efecting a thorough separation ofthe particles to be dried and allowingamorecompleteevaporationofthe moisture. Thefurther evaporation of the moisture thrown off from the drying feed is assisted by a current of heated air, which is produced by passing the condensed steam through a coil of pipelocated in an iuclosiug-chamber. The air thus heated is caused to pass, by means of a suitable ventilatingliue, through the cylinder and in contact with the drying feed. Another important feature of my improved drier is that by inclosin g the revolving cylinder in a chamber and admitting cold airtherein I am enabled No. 249,677, dated November 15, 1881,
(No model.)
wheels or rollers b. It is revolved upon these.
rollers by means ofa gear-wheel, c, operated by suitable power. Longitudinal buckets d, for lifting the feed, are riveted to the interior surface of the revolving cylinder. Two hollow drums or heads, c c', are secured inside ofthe cylinder, at or near either end thereof, by means of a suitable number of brackets, c2, and adjusting-screws e3. rlhe in terior surfaces of these drums are perforated to admit a seriesof connecting-pipes, f. Steam is admitted to drum e by means of a supply-pipe, g,aud an exhaustpipe, g', is fitted to drum e for conveying the condensed steam to a coil of pipe, g2, located in the inclosing-chamber h. This chamber incloses the entire cylinder, and is provided with a partition, h', which serves to prevent the heated air from passing out through the ven tilating-ue 7c3 before it has passed through the cylinder, where it is utilized in the drying process.
k is a diaphragm extending nearly to the top of chamber h, and serves to direct the lighter particles of feed (which are carried by the current of heated air) into the passage 7c', where they fall and are collected at the point k2. By this arrangement I am enabledto save a considerable portion of feed which would otherwise pass away through the ventilating flue 7c3 and be lost.
lis a hopper, and l a chute, by means of which the feed is introduced into the cylinder. The dried feed is discharged from the cylinder through hopper m.
n a are openings in the side of theinclosiugchamber for the admission ofV air.
rIhe operation of my deviceis as follows: The
feed-is introduced into the cylinder through thechute, and is carried up and dropped upon the heated pipes, and,fallingbetween said pipes to the bottom ofthe cylinder, is again lifted in the same manner as before. This operation is repeated until the feed gradually Works toward the lower end of the cylinder, Where it is discharged.
The distance between theedges of the buckets and the outer pipes is animportantfeatnre of my device, as by these means a more complete Separation ofthe moist particles of feed is eected. By means of the coil of pipe g2, into which the condensed steam passes, I am enabled to heat a current of air introduced into the chamber lb from the outside through openings n n, and by means ot' my Ventilatingflue pass such current of heated air through thc cylinder to operate in further drying the feed. The inclosing-chamber h, by means of its partition h', enables me to utilize the radiated heat of the cylinder (which has heretofore been wasted) and effect a more complete drying of the feed than has ever before been accomplished by the old forms of driers.
I claim- 1. In a feed-drier, the combination,\vith an inclined revolving cylinder, provided with buckets, of a system ot' steam-pipes located in and revolving with said cylinder, and means for collecting` and utilizing in the drying process the heat from the condensed steam and the radiated heat of the cylinder, substan tially as shown and' described.
2. In a feed-drier, the combination of cylinder a, hollow drums or hcads e e', pipes ffand g g,coil g2,inclosingchamber h,with partition h', diaphragm k, passage k, and Ventilatinglue k3, substantially as shown and described.
3. In a feed drier, as a means ot' collecting and saving the lighter particles of feed, the chamber It, with its partition h', the diaphragm k, passage 7;', and Ventilating-tine It, substan' tially as shown and described.
