- MODE OF OBTAINING EXTRAGTS. No. 46,809. Patented Mar. 14, 1865.

(IMI/IIII/IIIIIIfi/IIIIIIIIII UNITED STATES PATENT OFFICE.

BENJAMIN e. MARTIN,OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED MODE O FOBTAINING EXTRACTS.

Specification forming part of Letters Patent No. 416,809, dated March 14, 1865.

water which is afterward introduced may be brought into intimate contact with every particle of the material. and dissolve all the soluble portions of the same.

. -My invention further consists in an appara tus, fully described hereinafter-, for carrying out my improved mode of obtaining decoctions.

In order toenable others to practice my invention, I will now proceed to describe the manner of carrying the sameinto effect.

On reference to the accompanying drawings, which form a part of this specification, Figure l is a sectional elevation of an apparatus for carrying out my improved mode of obtaining decoctions, and Fig. 2a plan view.

Similar letters refer to similar parts in both views. I v

A is what is technically termed a mash-tub, and is a cylindrical vat or boiler, of wood or metal, supported, in the present instance, on

legs B. At the under side of the mash-tub is a fire-box, 0, through the upperpart of which passes a pipe, 1), the latter communicating with the mash-tub, and having at its outer end a cook, a.

E is a metal tank, in the center of which is a conical casin g, b, the latter being open at the bottom, and both the tank and casing being perforated to the height of the top of the lat ter. From the upper edge of the tank extends a flange, c, to which are attached the lowerends of a number of ropes or chains, 2, connected to suitable apparatus by means of which the tank may be raised from the mashtub. Around the outer side of the tank E is a jacket, E, which extends above the perforations in the tank, and is closed at the top and open at the bottom. In one side of the tank,

opening, through which projects the upperend of a conical-vessel, G, the bottom of the latter being perforated, and from the top of the same projects a pipe, f, which communicates in any suitable manner with a reservoir containing warm water. Above the top of the cover F is a hopper, g, which is covered by suitable lids, h h.

At the bottom of the tub A is afiat case, H, intowhichsteam is admitted through tubes i and i,

' Iis a vat, which is provided with 'a false bottom, It, and 'withthe space between the latter and the truebottom. k. communicate the pipes mm, for a purpose described hereinafter.

Operation: The material. of which a decoction is to be obtained is first introduced into the tank E. The lids h are then closed, and

v one-third of the water which is to be employed in obtaining thedecoctiou is introduced into the vessel G, and is distributed from the latter over thematerial in the tank. After percolating through the material the'water passes through the perforations in the tank into the tub A, where it is maintained atthe required temperature by the heat imparted by the steam-case H. In about-an hour after the introduction of the water the tank E is withdrawn from the mash-tub bymeans of the chains 2, and the remaining two-thirds of the water is introduced through the-distributer G into-the tank,.from which it flows into the tub beneath. The tank is then lowered to' its first position. As the tank descends'into the water in the tub, the air confined beneath.

thejacket E, as well as that in the casing 1),. will be forced by the pressure of the water through the pcrforationsin the tank and its casing and into the mass of material in the former, the particles of the said material being thus so separated from each other that on the admission of the water the latter will be brought into intimate contact with every particle. As the vapor arising from the heated liquor comes in contact with the inner surface of the cover F, it is rapidly condensed, and flows back again into the tank. When a decoction of the proper strength is obtained, theliquor. is drawn off through the pipe D E is elevated, and the spent material is re moved through the door d by means of a rakeor other suitable instrument. The tank is then again filled,and another decociion is obtained in the same manner as the first.

1 The method heretofore pursued of obtaining decoctions has been to introduce the material of which the decoction is to be made, together with water already heated, into a vessel, and then to stir the whole until the water is charged ,with' all the matter it will dissolve. It is then drawn 01f and another supply of water admitted, this operation being repeated until all the'soluble portions of the material capable of being extracted are obtained. This operation is tedious and expensive, and the soluble portions are but imperfectly extracted, owing to the material caking or setting, so that the water is not brought into contact with many particles of the same. This is especially the case in brewing. In this operation'also the'escapin g vapor from the vat carries with it much of that portion ofv the material which contributes mainly to impart a flavor to the decoction.

By the process above described the water is brought into intimate contact with every por tion of the material, and as the liquor is maintained at ahigh temperature during the entire operation, the soluble portions of the material are completely extracted without an undue expenditure of time and labor. By this process, also, the flavor is retained, and thedecoc tion made is greatly superior to that obtained in the usual manner.

In case it is desirable, the hopper 9 may be dispensed with, the material beingintroduced into the tank through a suitable opening in the'coven, It will also be apparent that a coil of steam-pipe may be substituted for the case B, and in some instances, where steam cannot be readily obtained, the liquor in the vat may be heated by means of a fire in the I claim as my invention and desire to secure by Letters Patent-- 1. Separating the particles of a material ot which a decoction is to be made by introducing into a body of the said material a current or currents of air, fort'lfi purpose specified.

2. The perforated casing E, with its jacket E, combined with the tub A, and operating substantially as and for the purpose specified.

3. The condensing casin g or cover F, com bined with a mash-tub, substantially as and for the purpose set forth.

4. The fermenting-vat I, with its false bottom k, and pipes m m, or their equivalents.

In testimony whereof I have signed my name to this. specification in the presence 0: two subscribing witnesses.
