ATENT NlTE STATES ADOLPH YVAHLIN, OF STOOKHOLM, SXVEDEN, ASSIGNOR TO RICHARD DUNCAN HARRIS, OF NEW YORK, N. Y.
CENTRI FUGAL SEPARATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 447,530, dated March 3, 1891.
Application filed June 21, 1890. Serial No. 366,272. (No model.)
To aZZ whom it may concern.-
Be it known that I, ADOLPH \VAHLIN, a subject of the King of Sweden, residing at Stockholm, Sweden, have invented an Improvement in Centrifugal Separating Apparatus, of which the following is a specification.
This invention relates to a device for separating the buttery particles from cream, and it is especially applicable to centrifugalseparators already upon the market.
In my present improvements the cream, after it has been separated from the skimmilk, instead of passing into a stationary receptacle, as heretofore usual, passes into a butter-separator connected with the creamseparator and extending out beyond the place where the cream is delivered, and such butter-separator is formed with a range of concentric ledges that arrest the outward movement of the cream and intensify the centrifugal separating action upon such cream, and the buttery particles pass over the edges of the ledges in succession, and in so doing the skim-milk flows away in a thin layer from the buttery particles, and such buttery particles accumulate and form granules or lumps of a sufficient size to be easily separated from the skim-milk by a sieve or similar device after the skim-milk and the buttery particles have been discharged from the centrifugal separator.
There being numerous centrifugal separators now in the market, my present improvements are to be adapted in size, shape, and mode of connection to any one of these separators.
I have represented by a sectional view, Figure 1, the upper end of an ordinary centrifugal separator with my improvements applied thereto; and Fig. 2 is an inverted sectional plan view of the apparatus at the line a; so of Fig. 1. Fig. 3 is a sectional view of a portion of the apparatus with the cream-separator opening upwardly.
The milk is to be supplied by a pipe A, or in any other convenient manner, into the cen trifugal separating-vessel l3, and the cream and skim-milk are separated by the centrifugal action in the usual manner. If the cream is delivered over the upper edge of the centrifugal vessel through notches 2, then my present device is applied around such upper edge. If the cream is delivered at the bottom or at any intermediate place, my improved butt-er-separator is located at whatever point is the most convenient for the reception of such cream. The skim-milk-delivery pipe is represented at 14 and a receiving-vessel at 15. These are of any usual character.
My butter-separator O is made approximately conical, and it is provided with annular ledges 3 4 5, the same being more or less numerous than those shown. Ilence as the cream is delivered from the separator I3 it accumulates in the first annular channel adjacent to the ledge 3, and finally flows over the ledge 3 into the next annular channel, and so on, there being a pause in the outward movement of the buttery particles in each of the annular channels, and as the supply of cream crowds the particles of butter and skim-milk over each annular ledge in succession the buttery particles, being lighter,
and slightly adhesive, do not pass away as rapidly as the skim-milk. Hence the skimmilk spreads as a thin film upon the ledge and the buttery particles accumulate and adhere togetherin increasingly large grains or lumps until delivered. The butter-separator may open upwardly, as indicated in Fig. 3, or it may open downwardly, as shown in Fig. 1, and the buttery particles may be taken off by a scoop, as indicated by dotted lines at'G, or both the buttery particles and the skimmilk may pass through the tube 7 into the annular chamber D, within which the buttery particles and skim-milk are subjected to a more powerful centrifugal action, and the buttery particles accumulate upon the inner surface and the skim-milk is against the inner side of the outer wall of the chamber, and it is preferable to employa pipe 8 for the discharge of the skim-milk and to remove the buttery particles by a scoop or similar device, as shown at 10, such buttery particles being taken away from the inner surface of the materials in the annular chamber. If, however, the buttery particles and the skimmilk are allowed to pass away together through the tube 7 into any suitable stationary receiving-vessel, the buttery particles may be retained within a fine sieve and the skimmilk allowed to run away.
ln place of the scoop 10, the buttery particles may overllow and pass out through a pipe represented by dotted lines at 1.2,Fig. 1.
If desired, a portion of the skim-milk may pass from anyone or more annular troughs t0 the next through a small tube, as indicated at 13, Fig. l.
I claim as my invention 1. The centrifugal b'utter-separator having an approximately conical form and a series of annular lodges upon its inner surface, the cream being received at the smaller end of such butier-separator, in combination with an annular chamber r relying with the butterseparator, there being an openingfor the discharge of the buttermilk and butter from the butter-separator into the annular chamber, and a discharge-opcning for the buttermilk, substantially as set forth.
The conical centrifugal butter-separater, over the surface of which the cream is caused to pass outwardly and discharge from the larger end, in combination with a surrounding annular chamber connected to and rotating with the butterseparator and receiving the materials therefrom, and provided with a dischargeopening for the skim-milk, substantially as specified.
A centrifugal butter-ext ractor having internal annular ledges, over which the buttery particles are caused to pass in succession as the skinrmilk is thrown off from the same, in combination with an annular chamber connected to and revolving with the butterseparator, and into which the buttery particles and skim-milk are received, and a pipeopening at one end near the innersurface of the wall of the annular chamber and at the other end outside the apparatus for the passage of skim-milk, and means for removing the buttery particles from the inner surface of the annular layer within the annular chamber, substantially as set forth.
Signed by me this 18th day of June, 1890.
