APPARATUS FOR CONVERTING Dl STlLLERY-SLOP INTO DRY FEED.

SPECIFICATION formingpart of Letters Patent No. 761,571, dated May 31, 1904. Applicatioufileii October 12,1900. Serial No. 32,900. (No model.)

To all whom it may concern:

Be it known that we, CHRISTIAN ANDERSON.

of Peoria and State of Illinois, have invented certain new and useful Improvements in Apparatus for Converting Distillery-Slop into Dry Feed; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an apparatus for converting slop into a dry feed forlive stock.

In our Letters Patent No. 653,645, issued:

July 30, 1900, we describe a very eflective method for separating the thin slop from the.

thicker portions, consisting of a system of settling-tubs, filter-presses, and other devices, and in this application WG'dGSiIG'bO show the mechanical apparatus for accomplishing the purposes set forthin that patent. The separation of the thin slop from the thicker solid parts can of course be accomplished by mechanical devices-:such, for instance, as filterpresses, filter-boxes, strainers, seives, or centrifugal machines. These methods of separation, however, are too well known to require elucidation here.

Our object is to make this separation andthen subject the thinner liquid slop to vacuum process while the thick solid portion is finished on suitable driers. The syrup resulting from the thinportion may be mixed with the thick portion before it is dried or mixed with chaff or coarse feed or dried separately or mixed or run into the fresh slop and again passed through the filter-presses or converted into dry feed through any suitable process for this purpose.

Another object of this invention is to employ a machine for breaking the feed from the pressesinto fine particles, so as to make it more suitable for the drier and avoid lumps 'and Wet feed in the finishedproduct.

the meshes of the cloth in the separator whenever in the process ,of the manufacture they again reach that machine, thereby producing feed of great uniformity.

In the drawing our improved apparatus is shown in elevation," the various elements thereof being distributed upon several floors in order to have them in proper relation to each other, although other arrangements of course are possible.

A indicates a tub for receiving slop through a pipe (0 from the distillery.

Bis a filter-press, to which the slop fro the said tub A is raised by means of. a pump C and pipe D. Thesaid filter-press may of course be substituted by any equivalent of well-known devices to serve the same purpose. A receiver E for thin slop is located beneath the filter-press and receives the extracted portion from the latter through a pipe F.

Gr indicates a breaker which receives the dry materials from the filter-press through a conveyer Hand spout I. This machine Gr reduces the cakedportions to small particles before being allowed to enter the drier J through spout K, so that they be quickly and thoroughly dried during the passage through the said drier J. An elevator L receives the dried portions from the drier J and carries from said separator are carried through a spout- Q into a reduction-machine R and there reduced to fine particles and from thence into a hopper S. Beneaththe hopper is a conveyer T, which receives the material through a gate or valve U, the latter being provided to regulate the bulk of material passing fromthe hopper into the conveyer. Connected with the receiver E through a pipe E is a vacuumapparatus V, into which the thin slop from said receiver is run. Said apparatus may be of any approved. form and used either singly or in multiple. The syrup derived from this apparatus is conveyed through a pipeW to the conveyer T, where it is mixed with the material from the hopper S. The amount of the dried portion to be used is regulated by the valve U, whereby the desired mixture may be had. A mixer Xbeneath the conveyer serves to more fully mix the material before it is allowed to pass into the slop-tub A.

From the foregoing it will be seen that the slop from the distillery is first put under pressure to separate the thin and thick portions, the latter being passed to the drier, but first reduced by the breaker G. From said drier the dry feed is run over the separating-machine M, the finished material, or that which passes through the cloth of the separator, is carried to a storage-compartment, while the coarse tailings are run to the hopper S to be mixed with the syrup from the vacuum apparatus for further treatment, as described, or are run over thereduction-machine before such mixing. The mixed portion may be carried direct through the drier to carry off the moisture or run into the slop-tub A to be again passed through the filter-press and this process continued until all is worked into dry feed.

It is evident that the above process may be very materially altered and varied and still the final results be the same. The breaker, the separator, the mixing-conveyer, hopper, and mixer may all be dispensed with. The mixing may be done in tub A or any other receptacle for such purposes. Additional tubs and leaders may be introduced to facilitate the work or meet construction of buildings. However, none of such things interfere with the treatment of the thin slop in a vacuum for the purpose of converting it into dry feed. The entire vacuum apparatus may be dispensed with and the breaker G or the reduction-machine R will still perform the service claimed for them.

The use of a breaker introduced so as to break up the thick solid slop-cakes before they enter the drier, a reduction-machine to grind the tail ends from the separator, the use of a vacuum apparatus in slop-drying are as far as we know new and have not been'used in slopdrying machinery before our invention.

We claim 1. An apparatus for making dry feed from distillery-slop consisting of means for separating the thin from the thick slop, a vacuum apparatus for receiving the thin slop from the separator and driving off the moisture therefrom, an apparatus for receiving and drying the thick portions from the separator, a reel for receiving and separating the fine material from the coarse after leaving the drier, means for conveying said material from the drier to the said reel, means for reducing the coarse material from said reel, a mixer for receiving the ground material from said reducing means and the resulting syrup from the vacuum apparatus, means for conveying the syrup to such mixer from the said vacuum apparatus and means also for conveying the reduced material of the said reducing means to the mixer, the mixed material being incorporated with the untreated slop coming from the distillery, the finer portions from the reel constituting the finished product.

2. An apparatus for making dry feed from distillery-slop consisting of means for separating the thick from the thin slop, a vacuum apparatus for receiving the thin slop and driving off the water therefrom to leave a residue, means for conveying the residue to the untreated slop from the distillery, means for reducing .the thick material from the separator, means for drying the material from the reducer, a reel for screening the dried material from the drier, means for conveying the said material from the latter to the former, a second reducing means for receiving and reducing the coarse material from the reel, means for carrying the material from the reel to the reducing means, a mixer for incorporating the reduced material from the reducing means with the residue of the vacuum apparatus, means for conveying the material from the reducing means to the mixer, the mixed product being returned to the untreated slop from the distillery.

3. An apparatus for making dry feed from distillery-slop consisting of means for separating the thick from the thin slop, an evaporating apparatus for receiving the thin slop and driving off the water therefrom, the residue therefrom being returned to the untreated slop, a breaker for reducing the thick solid portions of the material as it comes from the separator, means for drying the said reduced material, a reel for screening the dried material to separate the liner portions as the linished product, means for conveying the dried product to the reel, a reducer for the coarse portions from the reel, a mixing device for incorporating the residue of the evaporating apparatus with the reduced coarse portions from the reel, means for conveying the material from the reel to the mixer, and means also for conveying the residue of the evaporating apparatus to such mixer substantially as set forth.

In testimony whereof We afiix our signatures in presence of two Witnesses.
