Specification of Letters Patent.
Patented Oct. 18, 1910.
Application filed April 2, 1910. Serial No. 553,113.
Haven and State of Connecticut, have invented certain new and useful Improvements in Emulsifiers, of which the followirig is a specification.
My present invention relates to an emulsifying apparatus for liquids, such as milk, which contains fat lobules, and it has for its object to provide a relatively simple,
etlicient and reliable apparatus of this character which embodies means for dividing a flowing body of milk, under pressure, into a plurality of relatively minute streams which are directed against the peculiarly arranged surfaces and also against each other at such a velocity as to break up the fat globules to such an extent as to homogenize the product and prevent rising of the fatty constituent-s to the top of a body of the liquid.
To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.
In the accompanying drawing Figure 1 represents a sectional View of an emulsifying or homogenizing apparatus constructed in accordance with my present invention; Fig. 2 represents a transverse section on the line 22 of Fig. land upon an enlarged scale showing the formation and arrangement of the grooves or passages upon the surface of each disk or element; and Fig.3 represents a transverse section taken diametrically through one of the emulsifying disks or members.
Similarparts are designated by the same reference characters in the several views.
' An emulsifying or homogenizing apparatus constructed in accordance with the present invention is shown in its preferred form in the accompanying drawing, it consisting of a casing 1 and a pump 2, the latter being capable of delivering a flowing body of the milk or liquid to the casing at a relatively high pressureiand continuously. The casingl in the present instance 1s provided witlr-a bore- 3 which is preferably cylindrical, and a passage 4 leads to the bore 3 preferably at a perpendicular thereto, this pas- .sage l communicating with the pump. In
the present instance, the casing is provided with a flange 5 and a boss 6 which form a member of a coupling whereby the casing may be firmly attached to the outlet of the high pressure pump.
A shoulder is formed toward the outlet end of the bore 3 preferably by a removable or separately formed bushing 7, the latter being threaded or otherwise tightly fitted into the casing, and it also has a head or flange 8 which bears upon a packing ring 9 so as to form a perfectly fluid-tight fit upon the casing. This bushing has a bore 10 through which the emulsified or homogenized liquid may discharge from the casing, and a delivery pipe or other means may be attached to the bushing 7 to conduct the emulsified liquid to any desired point.
The emulsifying or homogenizing action is produced within the casing by a set of assembled or superposed elements which are held positively in intimate relation under heavy compression and have relatively minute passages or ducts through which numerous streams of the liquid are directed at high velocity and are caused to impinge upon suitable surfaces that will cause disintegration of the fat globules. I preferably employ a set of disks 11 which are duplicates and are mounted or arranged in superposed relation Within the bore 3 of the casing. Each disk is flat and its opposed surfaces are ground or formed perfectly true so that when the disks are assembled, they will fit precisely against one another. The periphery of each disk is provided with a suitable number of bosses or lugs 12 which are adapted to rest against the wall of the bore 3 of the casing and thereby center the disks therein and at the same time form a number of segmental circumferentially spaced passages 13 between the set of disks and the wall of the bore. The disks are placed at that point in the here where the passage 4- communicates therewith, and in order to permit the body of milk flowing from the high pressure pump through the passage 4 to reach all of these segmental passages 13, the faces of the bosses or lugs 12 are reduced or tapered as at 14 whereby means of communication between these circumferentially spaced passages Will be established. The center of also against surfaces which are so arranged distantly as to cause the disintegration of the fat globules. In the resent instance, the dividing of the body 0 the liquid into the minute streams is effected by forming minute assages orducts between the adjacent disks. These ducts may be conveniently.formed by grooving one or both faces of-each disk.
I generally prefer to groove both faces of each disk in order to insure to the greatest degree a thoroughness in the operation and, moreover, the apparatus has a greater capacity in that case. In the present instance, I provide the faces of each disk with an annular or circumferential groove 15 which is preferably concentric with the axis of the disk, and two sets of inwardly extend.- inggrooves 16 and 17, the grooves 16 extending from the periphery-of the disk to and communicating with the circumferential groove 15, while the inner set of grooves 17 lead from the circumferential groove 15 to the aperture 14 in the center of the disk. These two sets of grooves 16 and 17 are preferably arranged in radial relation and they are also staggered with respect to" one another, the radial relation of the grooves 16 and 17 to the circumferential groove 15 causing the liquid to' be projected into the circumferential groove 15 at a normal, and the staggered or alternating relation of the I grooves 16 and 17 will cause the liquid from each groove 16 to be projected abruptly against the 'wall=of the roove 15, whereupon this stream of liquid is divided into equal bodies which flow in opposite directions around the circumferential groove 15 and these divided bodies from one radial groove 16 meet the equal divided bodies of liquid flowing in reverse directions from'the adjacent grooves 16 at the entrance to the radial grooves 17 the impact of these equal bodies of liquid at such points insuring complete disintegration of the fat globules and also diverting these streams or bodies of liquid into the grooves 17, this result being secured by spacing one set of radial grooves about the circumferential groove 15 equior midway between the other set of radial grooves.
following any. other course than through the passages provided for the liquid, and any top of the set of disks and a compression screw 19 bears upon a seat formed upon the top or outer end of the plunger, this compression screw being fitted into a yoke or other suitable support 20 attached to the casing, and a packing is provided for the plunger which will effectively preventthe escape of the liquid under high pressure. This packing in the present instance consists of a cupped packing ring 21 which encircles the plunger 18, a gland 22 bears upon the packing ring, and a nut or cap 23 bears upon the gland 22 and is threaded or otherwise suitably attached to the casing.
I claim as my invention a 1. An emulsifying or homogenizing device comprising a casing having a passage for conducting a flowing body of liquid and also having a bore communicating therewith, a set of centrally apertured disks assembled in said bore, each disk having a face formed with a circumferentially extending groove, and sets of inner and outer radially extending grooves arranged in alternating relation, the radial grooves of one set communicating with said circumferential groove at points equidistantly between the points where the other set of radial grooves commupicate with said circumferential groove, and means for maintaining a positive compression upon the assembled disks to cause the liquid to fiowsolely through disks assembled in superposed relation in said bore, each disk having an inner aperture for the passage of liquid and also having intimately engaging faces, a face of each disk being formed with a circumferentially extending groove and sets of inner and outer radially extending grooves arrange in alternating relation, the radial grooves of one set communicating with said circumferential groove at points equidistantly between the points Where the other set of radial grooves communicate with said circumferential groove, said grooves'constituting the sole means of communication for the liquid be-" tween said bore of the casing and the inner apertures of the disks, the major portion of each disk being smaller in diameter than said bore in the casing and having a plurality of circumferentially spaced bosses which cooperate with the wall of said bore and thereby center and position the disks grooves in their faces.
