This application April 26. 1944, Serial No. 532,720

8 (Halms. (Cl. 146-78) This invention relates in general to an improvement in winery equipment, and in particular the invention is directed to unique apparatus for separating different grades of Juice from grapes.

As is well known in the wine-making industry, initial mild crushing and pressing of wine grapes produces a clear unadulterated Juice which is requisite for the manufacture of champagne, this mild crushing and pressing avoiding the rupturing of those inner cells of the grapes which carry the colored juice undesirable for champagne, but which is used for common wines. In addition, with this mild action the grape stems remain intact and the acid therefrom does not escape into the clear juice, as would occur if said stems were detached or mashed.

This application is a substitute for abandoned. application, Serial No.- 413,419, filed October 3, 1941.

The old practice to obtain the clear juice for champagne was to place the grapes in a wine press and then slowlyapply an easy pressing action. The clear juice was then drawn oil, and subsequently the forceful pressing action was applied to obtain the colored juice as used for the common types of wine. However, this practice was slow, tedious and not well adapted to largescale production.

It is therefore the principal object of this invention to provide a novel power driven juice separator which is operative to effect, as a contint-Jus process, a separation from grapes of the clear unadulterated juice intendedfor the manufacture of champagne.

A further object of the invention is to provide apparatus, as above, which is designed to assure against separating or mashing of the grape stems, and to thus prevent acid from said stems entering the clear juice beim produced.

An additional object of the invention is to provide a juice separator of the type described which includes a unique assembly of crushing rolls.

It is also an object of the invention to provide a unique method of separating from grapes the clear juice desired for the manufacture of cham- A further object of the invention is to produce a simple and-inexpensive device, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the followins specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a side elevation of the improved Juice separator.

Figure 2 is an enlarged cross section taken on line 2-2 of Figure l.

Figure 3 is a diagrammatic end view showing the preferred form of drive for the crushing rolls.

Referring now more particularly to the characters of reference on the drawings,- the juice separator comprises a rigid, elongated and hori- 'zontally extending frame, indicated generally at i, having transverselyspaced sides; a substantial portion of the apparatus being. mounted between said sides, as hereinafter described.

At one end the frame includes a plurality of upstanding corner posts 2, which form in effect a tower extending above thehorlzontal plane of the frame i; such tower having a relatively tall hopper 3 rigidly suspended therein, two sides of said hopper being parallel, asshown. Apair of metallic rolls I are disposed in the hopper substantially centrally between the upper and lower ends of the latter, such mils being carried on horizontal shafts 5 which are disposed lengthwise of the elongated frame I. The rolls 4 are formed at the periphery with teeth 6 which extend the full length of the rolls and face in the direction of rotation; the rolls 4 rotating in opposite directions and so that the upper peripheries thereof move in approaching relation.

Below the rolls 4 is another pair of rolls I, these rolls-being ofvery soft, resilient rubber, and of somewhat lesser diameter than the rolls I. The rolls I are supported by shafts I which are parallel to the shafts ii. The rolls I have longitudinally extending slots 9 formed therein about their entire periphery, these slots being closely spaced circumferentially. V

The outer end portions of the shafts 5 and 8 project through the adjacent sides of the hopper 3 and are suitably iournaled and supported in connection with cross members III which extend between corresponding comer posts 2; the shafts of each pair of rolls being :Iournaled for adjustment in a direction to and from each other. and as indicated diagrammatically and by dotted lines at H in Figs. 2 and 3.

In normal operation the upper rolls I are spaced apart slightly at their peripheries, while the soft rubber lower rolls 1 are substantially in eripheral contact.

The shafts 5 and I! extend axially some distance beyond the adjacent end of the frame I and are fitted with sprockets l2 and I3 respectively. A horizontal drive shaft I4 is journaled on the frame I below sprockets I3, and this drive shaft is fitted withdrive sprocket I5. An endless chain I6 extends from sprocket I upward about sprockets l3 in reverse drive relation, thence extends over an idler sprocket I1 'mounted on one of the corner posts 2, and from there extends back to the drive sprocket I5.

A substantially horizontal shaker table I 8 is disposed lengthwise betweenthe sides of frame I adjacent the top of. the latter and with one of its ends disposed in receiving position below the lower and discharge end of hopper 2. This shaker table is supported on both sides by longitudinally spaced resilient supporting members IS, the lower ends of which are mounted in connection with cross members 20 of the frame. The shaker table is is formed with a finely perforated bottom plate 2|. The shaker table is actuated by eccentric units 22 mounted atop the frame I and having connecting rods 23 secured at their outer end to the shaker table. The eccentric units 22 are actuated by a shaft S driven in any suitable manner. A catch or drain pan 2| is mounted within the frame I below the shaker table 2|, said pan sloping toward one side and having an outlet conduit 25 depending from the low point, such conduit having a T-fitting 26 at its lower end. A carry-off pipe 21 is connected with said fitting, and has a valve 28 interposed therein. At the end remote from hopper 2, the shaker table II feeds into a chute 29 which in turn discharges into the adjacent end of a rotary, screen type mesh stemming unit 30 which is of conventional construction; such unit 30 having the drum portion mounted on a substantially horizontal shaft 3| journaled lengthwise in frame I in suitable manner. The shaft 3| extends the full length of frame I below the shaker table to a. termination beyond the endless chain I6, being there provided with a sprocket 32 driven from a large diameter sprocket 33 on drive shaft ll by means of an endless chain 34.

Another catch pan :5 is mounted in frame I below the mash stemming unit 30, and a discharge pipe 38 leads downward from the low point of such catch pan 35. Juice from catch pan 2, if not needed for separate use, may be bypassed into discharge pipe 36 by means of a normally closed valved pipe 31 which extends from fitting 26 to pipe 38. A discharge chute 3| is mounted in receiving relation to the outer and discharge end of the drum of unit 30 to receive the grape stems.

In operation, bunches of grapes are placed in hopper 3 whereupon they are at once engaged by the upper rolls 4 which effect; first, a disintegration of the bunches into separate grapes; and, secondly, an initial rupturing of the skin of said separate grapes. The grapes then fall below rolls 4 and are engaged by the very soft rubber rolls 1, which efiect a mild crushing action which does not break down the center portion of the grapes. In the above manner the outer portion of the flesh of the grapes, and which carries the clear juice, is efiectively macerated without any mashing of the relatively hard stems or the interior of the grapes. From rolls I the partially crushed grapes fall onto shaker table II, the action of such table being forceful and'causing a release of the clear juice which filters through the perforate bottom plate 2I of such table into catch pan 24 and thence into conduit 25. The balance of the crushed grapes-then in t e m of mash-passes off the discharge end of the shaker table, down chute 29 into the rotary stemming unit 30. The action of this unit effects a clean separation of the stems from the mash; the mash passing through the screen of the unit, and the stems still in unbroken or uncrushed form being fed out of the ends of such unit into chute 38. The mash from rotary unit 30 is received in catch pan 35, whence it is carried through pipe 36 for further processing.

The juice which is caught in pan 24 is clear and unadulterated, and is that which is used for the manufacture of champagne, whereas the mashwith its inc'luded colored juice-which is received in catch pan 35,'is that which is employed to manufacture the more common types of wine.

From the foregoing description it will be readily seen that I have produced such-a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:
