JOHN WV. BROWN, OF BROOKLYN, NEW YORK.

APPARATUS FOR DRYING MALT.

SPECIFICATION forming part of Letters Patent No. 277,876, dated May 22, 1883.

Applicationfiled September-12,1882, (No model.) i

To all whom it may concern:

Be' it known that I, JOHN W. BROWN, ot

Brooklyn, county of Kings, and State of New described for drying the said grain or malt,

My invention relates to the drying of the grains or malt of brewers as the same comes from the mash-tubs, for the purpose of improving the condition of said grain or malt as food for cattle and stock; and my invention consists in the improved apparatus hereinafter composed of a grain or malt chamber closed from the air, and having a perforated bottom,

' beneath which is a chamber for heating air,

together with an air-exhaust apparatus leading from the upper part of said malt-chamber, all as specified.

Figure 1 is a side view of an apparatus embodying my invention, the walls being partly cut away to disclose the interior mechanism. Fig.2 isa plan of the lower or air-heatingchamber, showing the'steam-coil; and Fig. 3 is a section of the steam-coil, together with itsdri proof or guard. v l

A is a tub or vat having the continuous walls a, the solid bottom a, and the lid a which is capable of being hermetically closed, or substantially so. \Vithin this tub is arranged the false bottom B, placed more or less above the solid bottom a. Two chambers-are thus constituted within the tub, the large upper chamber, G, and the lower smaller chamber, O. The false bottom or partition is perforated, as shown.

Within the upper chamber, 0, is arranged a stirring apparatus, which may be in the form shown--namely, a fixed bevel-gear mounted rigidly on a stud, as at d, at the center of the .lower part of the chamber 0, with which gear engage the bevel-pinions (1, one of which-is on each of the shafts d carrying the stirring-arm d. The shafts d are hung in a frame, d and the frame and shafts are rotated by means of a vertical shaft, 61 which extends above the lid'of the tub. The frame and shafts being rotated within the tub by the driving-shaft d the pinions d, running on the gear (Z, will operate to lo tate the shafts d axially, and thus to revolve the arms d, and these latter will agitate and stir the contents of the chamber 0. I do not claim the said stirring devices as new, nor do I limit myself to the use of the same. Any other devices which will eEfectivelyagit-ate the contents of the chamber 0 may be employed. Within the chamber 0, and preferably elevated somewhat above the floor thereof, I arrange the steam heating-coil E. In the side walls of said chamber I provide openings and air-valves, (shown at (2.) Over the upper exposed surface otthe piping composing the steam'coil I preferably place the driproofs 0-, the same being composed of a strip of angle metal with its apex arranged to'project vertically above the line of the pipe, and with its longitudinal edges extending downward about the sides of the piping. By means of this driproof any moisture which finds its way through the perforated bottom will be prevented from falling upon the hot coil, and thus injuring the same, but will fall upon the roofing e, and pass down the same and fall to the bottom of the chamber 0 between the pipes.

Opening out of the top or upper part of the chamber 0 is the air-conduit F, leading to an air-exhaust fan or pump, F.

The operation of my apparatus is as follows: The steam-coil, being heated, warms to a high degreethe lower chamber, 0. In the upper chamber, 0, is then placed a quantity of wet brewers grain as the same comes from the mash-tubs. Power is then applied to the exhaust-fan F, and also to the stirring device, and atthe same time the air-valvesc areopened. The external air admitted through inlet 0 is heated in the chamber 0 and passes up through the perforated bottom 13 into the upper chamber, 0, being drawn into said chamber through the massot' the grain, and passes out at F and through the fan. At the same time the grain is continuously agitated by the stirring devices.

All the conditions essential for the successful and effectual drying of wet and hot brewery grain or malt are thus provided for in my apparatus, and such grain or malt thus dried is greatly improved and enhances in value as an article of food for cattle and other live stock.

What I claim as my invention, and desire to steam heating-coil E in said lower chamber, of secure by Letters Patent, isthe angular roofing-strips 6, arranged above 10 In an apparatus for drying brewery grain or the line of the piping of the coil, as described, malt, having an upper or grain chamber, 0, and for the purpose specified.
