Application filed February 19, 1916. Serial No. 79,805.
To all whom it may concern Be it known that I, EMANUEL M. LUND- omen, a subject of the King of Great Britain, and a resident of Stapenhill, Burtonupon- Trent, England, have invented an Improvement in Pasteurizing Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings repre 1 senting like parts. 4
The present invention relates to an apparatus for pasteurizing malt or other liquors, and is adapted for use in connectionwith packages for shipping containing relatively large quantities, it being preferable, though not essential, to use metal casks. It has been found impracticable, heretofore, to pasteurize beer in large receptacles for the reason that it is necessary in the pasteurizing process to heat the liquid in hermetically sealed packages, since air will spoil the beer if it gets into the liquid after or during the cooling process. Heretofore, therefore, the process of pasteurizing has been confined to small packages, such as bottles, in which the strength of the package is sufficient to withstand the expansion pressure due to the pasteurizing heat. When it comes to'a large quantity, however, it is impracticable to make a container of sufficient strength to stand the expansion pressure, and if a vent is provided, itis practically impossible to exclude air while the liquid is being cooled.
The present invention relates to a device for obviating these difficulties, and the device consists in a detachable expansion or overflow chamber which is also provided with inserting means for the cork or'bung, .this detachable chamber being so arranged that the air can be entirely excluded therefrom prior to the process and the cork inserted before the expansion chamber has been removed after the pasteurized liquor has been cooled. The excluded air may or I may not be replaced by carbonic-acid gas,
as desired.
Figure 1 is a longitudinal section of an apparatus embodying the invention shown as applied to a metal cask; and Fig. 2 is a similar view showing a modification which may be used if it is found undesirable to use carbonic-acid gas as the means for expelling the air.
Referring to Fig. 1, the device embodying the invention consists of a T-piece l which is adapted to be coupled or otherwise suitably secured to the bung hole of a recepta- I cle, a metal cask being preferably used in connection with this process, since it is bet ter adapted to be connected with the apparatus, and is also more suitable for the pasteurizing process. TheT-piece has a longitudinal bore 2 which constitutes a guide for the bung or cork 3, the said guide preferably having a tapered mouth 41 adapted to be stopped by a tapered plug 5 which is shown as having athreaded-flange 6 adapted to be screwed on an external thread 7 at the opening of the bore 2. An air tight fitis pro vided for by means of a washer 8; and the aper'ed portion 5 constitutes a stop for the cork 3 which prevents the same from blowing out under pressure while the liquid is being pasteurized. The said bore 2 has a lateral passage 9 communicating through a pipe 90 with an expansion chamber 10 of suflicient size to accommodate the pressure due to pasteurizing heat, the said pipe and chamber preferably being detachably secured to the cork guide as by a coupling 12. The said pipe 90 is also provided with a shut-off cook 13 to cut off communication between the cask and the expansion chamber.
In the construction shown in Fig. 1, thechamber 10 is provided with another pipe 1-1 which is adapted to be coupled to any suitable source of carbonic acid gas under pressure, the supply of gas being controlled by a cook 15.'; In the construction shown, the said cock15 is coupled between a nipple 16 at the end of the pipe 1 1 anda nipple 17 adapted to be connected'to the. pipewhich supplies the carbonic acid gas.
In utilizing the apparatus, the cork guide is first connected with the cask. Before the expansion chamber 10 is coupled to the cork guide, the cook 13 is shut off, and the-cock 15 opened, and the chamber is filled with water through the pipe 14, so as thoroughly to expel the air. The said chamber is then connected to the source of gas and the water expelled by the action of the gas while the cook 13 is opened, both of the said cocks 13 and 15 then being closed leaving the chamber absolutely devoid of air and full of carbonic acid gas. The chamber is then coupled to the cork guide and the latter filled with beer to the top, thus displacing all the air in the cork guide and in that part of the pipe which lies between the guide and the closedv pipe 13. The cask with the expansion chamber connected thereto is then tilted, thus expelling the extra beer, after which the cork 3 is driven into place, and the plug 5 screwed on. The cook 13 is then closed, and the package placed in the pasteurizing chamber and subjected to the necessary degree of heat for the required time.
In the cooling process it is obvious that the beer which has boiled over into the expansion chamber will run back into the cask, after which the plug 5 can be removed and the cork 3 driven into the bung hole. This finishes the process and the pasteurizing device is removed.
If it is desirable that the beer should not be associated with fresh carbonic acid gas, the gas used for the expelling pressure may be kept out of the expansion chamber by using a diaphragm or elastic wall to expel the water, the space for the overflowing liquid being provided for by the elasticity of the diaphragm. In this case, it is obvious that any other source of pressure may be substituted for the gas; but it is better to use carbonic acid gas, in case the diaphragm should burst. As shown in Fig. 2, the chamber 10 is provided with an elastic diaphragm 18, preferably of rubber, so that when the pressure is admitted through the pipe 14, the diaphragm will be forced as shown in dotted lines, into the pipe 9 thus expelling the air through the open cock 13. The air between the diaphragm and the said cock is then expelled, as previously described, by filling the bore 2 with beer as before, the cock 13 being left open during the entire process. In fact, when the diaphragm is used, the cock 13 may be dispensed with en- .tirely, the cook 15, however, being necessary to maintain the pressure behind the diaphragm. In this apparatus, the diaphragm 17 constitutes one wall of the expansion chamber which is empty instead of being filled with carbonic acid gas; although, if carbonic acid gas is used as the source of pressure, the chamber is charged with gas, so that no harm is done if the diaphragm leaks or is damaged.
What I claim is 1. A pasteurizing apparatus consisting of .a chamber provided with an inlet passage having a shut-01f cook; a stopper-guide communicating with said chamber; a second shut-01f cock between said chamber and said guide; means for connecting one end of said stopper guide to the bung hole of a cask; and means for closing the other end thereof.
2. A pasteurizing apparatus consisting of a chamber provided with an inlet passage having a shut-off cock; means for attachment to a source of carbonic acid gas under pressure; a stopper guide consisting of a tube adapted to be connected with the bung hole of a cask and also adapted to contain a stopper in line with the bung hole; a lateral tube leading from said stopper guide and adapted to be coupled to said chamber; and a tapered plug detachably secured to the open end of said stopper guide.
3. A pasteurizing apparatus consisting of a chamber provided with a communicating passage; a stop cock in said passage; a tubular cork guide open at both ends and adapted to contain a cork, said cork guide being in communication with said passage; and means for excluding the air from said chamber.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
