APPARATUS FOR SEPARATING GLUTEN FROM SLAUGHTER-HOUSE WASHINGS.

EPECIFICATION forming part of Letters Patent No. 445,054, dated January 20, 1891.

Application filed September 16, 1890. Serial No. 365,161. (No model.)

To ctZZ whom it may concern:

3e itknown that I, RUDOLPH GIEBERMANN,

a citizen of the United States, residing in the city of Chicago, in the county of Cook and 5 State of Illinois, have invented certain new and useful Improvements in Apparatus for Separating Gluten from Sla-ughter-I-Iouse \Vashings, of which the following is a specification.

It is well known that in the washings from slaughter-housesthat is, the water used in washing freshly-slaughtered animals during the dressing operation-there is contained a good percentage of blood, fat, glue, &e.,ordinarily designated as gluten, which, if separated from the water or washings, becomes a highly-valuable article of commerce sold for use as a fertilizer, but which, when discharged into a river or sewer with the washings, as ordinarily obtained, exhale noxious and disagreeable odors, which taint the air to a considerable distance about the vicinity of the slaughterhouse, frequently causing sickness and a depreciation of real-estate values in the neighborhood of the slaughter-house.

The prime object of this invention is to separate from the slaughter-house washings the gluten contained therein, thereby saving a valuable byproduct which has heretofore been wasted and at the same time cleanse and purify the Water discharged into the sewer, so as to avoid all noxious odors arising therefrom.

Another object is to separate the gluten from the washings during the continuous flow of the latter, whereby is avoided the necessity for the employment of storage-tanks for the washings.

These objects are attained by the devices illustrated in the accompanying drawing, in which is illustrated diagrammatically a plant embodying the apparatus of my invention.

Similar letters of reference indicate the same parts in the several figures of the draw- 1ng.

Referring by letter to the accompanying drawing, A indicates a pump of any suitable construction; B and (l, a pair of heaters; D, a precipitator; E, a small auxiliary pump, 50 and F a filter-press of any desirable construction, which devices collectively constitute my plant for separating the gluten from slaughter-house washings.

As before mentioned, the pump A may be of any suitable construction, its purpose simply being that of an ordinary force-pump for forcing the washings from a common reservoir through the rest of the apparatus.

The heaters B and (l preferably consist of cylinders a, having diaphragms 12 extending across each end thereof, forming chambers c in each end of the heater, which are connected by a series of tubes (1, the chamber occupied by the tubes between the diaphragm constituting a passage for the washings, as described farther on.

The precipitator D consists of a chamber 6, of suitable dimensions and of cylindrical or any other desired form, into which live steam is introduced from the pipef through the intermediary of a coiled pipe 9, contained within the chamber and perforated either externally or internally of the coil, or an injector of any suitable form may be attached to the pipe f and located within the precipitator, the purpose of the coil,injector,or other suitable device being to break the force of the steam, which is admitted to the chamber under considerable pressure, to avoid too much agitation of the washings in the precipitator.

The pump E may be of any suitable construction, its purpose being thatof a forcepump to inject alumina compounds into the washings either just prior to or at the time of their discharge into the precipitator, these compounds coacting with the heat of the live steam to cause the instantaneous and continuous precipitation of the gluten from the washings.

The filter-press F may be of any suitable construction for filtering the precipitated gluten from the washings during their passage through t-he press, which is generally composed of a series of distance-frames h and filter-plates t alternating with each other and arranged in a suitable frame, by which they are held together under sufficient pressure to render the joints between the plates and frames water-tight. The washings are delivered to any desirable number of the distanceframes, either every other one, every third one, or all of them,by branch pipesj, leading from the main feed-pipe k, connecting with the precipitator, the filtered washings or clear water flowing out through discharge-pipes Z, connecting the lower sides of the filter-plates with a drain-pipe m. p

In practice the washings, either in a cold or partially-warm condition, are delivered to the pump A by the pipe 42, connecting the pump with a common reservoir into which all of the washings of the slaughter-house are directed, and from the pump the washings are forced into and through the heater B,the lower portion of which is connected with the pump by the pipe 0, the washings in their passage through the said heater being warm ed by reason of the flowing through the tubes of the heater of the hot filtered water from the filter-press, which passes out of the top of the heater and through the pipe 19 to the sewer perfectly clear and in a practically pure and odorless condition. From the heater B the washings pass through the pipe qto the heater 0, where the temperature is still further raised, this heater being heated by the exhaust-steam from the pump A, which is connected with the upper end of the heater by the pipe 1', the condensations from the steam being discharged from the lower end of the heater into avat 5 provided for that purpose. The washings then flow on through the pipe 15 to the precipitator D, having mixed therewith, either prior to or at the time of their discharge into the precipitator, a suitable proportion of some alumina compound, which is injected into the pipe t or the precipitator by the pump E, as before described.

In the precipitator the washings are subjected to the action of live or superheated steam, which raises the temperature of the washings sufficiently, in conjunction with the alumina compound, to cause the instantaneous precipitation from the washings of all the gluten contained therein as rapidly as the washings are forced into the precipitator, from which they are discharged with equal, if not greater, rapidity under the combined force of the pump A and the steam flowing through the pipe 7; into the filter-press F, where, as before described, the gluten is filtered from the washings and the filtered and purified water is drawn off to subserve the purpose of heating the heater B before being emptied into the sewer.

An apparatus constructed in accordance with my invention is simple, effectual, and economical, and is principally designed for carrying out my process for separating gluten from slaughter-housewashings,for which I have made application for Letters Patent of even date herewith.

Prior to this invention, in efforts to purify slaughter-house washings, sewage, &c., it has been common to run the washings or other liquid into large tanks and there mix with it alum or other chemicals for causing the precipitation of the gluten; but that is the work of hours and sometimes of days and would be wholly impracticable as applied to slaughter-houses of the present time, in which hundreds of. thousands of gallons of washings are run oif each day, to handle which would require a storage capacity greater than the slaughter-house itself; but with my improved apparatus the precipitation of the gluten is rendered instantaneous and continuous, the gluten being extracted from the washings as rapidly as the washings are run, therebyavoiding the necessity for storage-tanks of any kind and at the same time greatlyincreasing both the capacity and product of the apparatusa most important consideration when it is re membered that the gluten constitutes a valuable article of commerce, being one of the best fertilizers known.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

1. An apparatus for separating gluten from slaughter-house washings, comprising a pair of heaters connected together for heating the washings to different temperatures, a precipitator connected withone of said heaters, a pump for injecting chemicals into the pipe connecting said heater and precipitator, a filter-press connected with said precipitator, and a force-pump for forcing the washings through all of said apparatus, substantially as and for the purpose described.

2. An apparatus for separating gluten from slaughter-house washings, comprising a forcepump, a filter-press, a pair of heaters, and a precipitator, said heaters being connected together and connected, respectively, with the pump and precipitator, one being heated by the filtered water from the filter-press and the other by exhaust-steam from the pump, and a pump for injecting chemicals into the pipe connecting one of said heaters with the precipitator, substantially as described 3. An apparatus for separating gluten from slaughter-house washings, comprising a forcepump, a filter-press, a precipitator connected with said press, a live-steam injector therefor, a pair of heaters connected together and respectively connected with the force-pump and precipitator, one of said heaters being heated by the filtered water from the press and the other by exhaust-steam from the force-pump, and a pump for injecting chemicals into the pipe connecting one of said heaters and the Witnesses:
