SM5, Fig. l; and Fig. 6 is a similar section on the line G-G of said Fig. 1.
The pasteurizing chamber comprises as usual in apparat-us of this kind, simply a tank like receptacle A that is preferably rectangular in form, so as to conveniently accommodate the crates or trays B, in which the bottles .7) are placed for steaming, as the pasteurizing process is frequently called. The dimensions of such receptacle A are chosen so as' to permit of the placing therein, and the entire submergence when so placed, of the desired number of crates, whether of pint or quart bottles, constituting thecapacity of the pasteurizer. Connected with opposite ends of the tank or receptacle, and on a level below the middle, is a pipe or conduit C lying wholly without said receptacle. Connected with such vexterior conduit or pipe near one of the points 7 5 where it is joined to the tank, is a steam injector C of well known construction, and hence not requiring detailed description here. By means of Such injectona circula tion of water through the receptacle and pipe can be maintained, the water being drawn from the receptacle at the end a adjacent to such injector, and returned thereto at the opposite end a. As will be readily understood, such injector serves at the same time to heat 'the water, thus put into circulation, so as to raise the same from the initial temperature,'which is generally relatively low, in order to avoid making the transitionin temperature too great when the bottles are firsty placed therein, to the proper pasteurizing temperature. Tha-t 1 such temperature may be auton'iatically maintained when it has been finally reached,
a thermostat D, likewise of familiar construction, is employed, such thermostat being mo-unted laterally of the tank, and near the same end from which the water has been To all whom it may concern:
Be it known that l, BRYAN D. PINKNEY, a citi-zen of the United States, and'a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Pasteurizers, of which the following is a specification, the principle of the invention being herein explained and Y the best mode in which I have contemplated lo/applying that principle., so as to distinguish it'` from other inventions. l
It is to pasteurizers of the tank, or chainless, type in contradistinction to the continuous pasteurizer that the present inll5 vention belongs, this classification of pasteurizers being that generally adopted in dealingwith those intended for use in beerbottling establishments and the like. As is well understood, the process of pasteuri- 20 nation in this connection consists in heating the beer in the bottles to a certain temperature, holding this temperature constant for a determined length of time, and finally cooling such `bottles to nearly ordinary at- 25 mosplieric temperature.,
The object of the present invention is the provision of a pasteurizer of the'tank type, wherein this change in temperature may be conveniently effected under suitable condi- 39 tions of control, and wherein the uniform heating of all parts of the tankscontents is assured, such uniform heating being a prerequisite to a sound condition of the goods, and the absence of such heating in 35 present'v pasteurizing operations being the cause of no small amount of trouble to the bottlerV and dissatisfaction on the part of the consumer.
To the accomplishment of the above and 40 related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims. The annexed drawings and the followmg description set forth in detailfcertain 5 mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle ofthe invention may be used. In said annexed drawings Figure 1, is a 50 plan View of a pasteurizer embodying my several improvements; Fig. 2, is a front elevation of such pasteurlzer; Fig. 3 .is a section thereof taken on the line 3 3, Fig. l;
55 Fig. fi is an end elevation ofj the same; Fig.
is a transverse cross-section` on the line seen to bc withdrawn by the injector. The thermostat is adapted by means of suitable air pressure connections d and a diaphragm valve D to appropriately operate the injector whenever the temperature at the point of attachment of the thermostat falls below, or rises above the predetermined tempera? ture. F or observation purposes a thermometer CZ is likewise mounted inl the same side wall of the tank or the receptacle as such thermostat.
From the foregoingdescription, it will be seen that the heating of the liquid contents of the receptacle is effected by means located Wholly exterior of the receptacle. lVhile the circulation of the receptacles contents, effected at the same time, Will serve'to render more or less uniform the temperature throughout the tank, the presence of the crates or trays of bottles will more or less hinder suchcirculation, and render its effects at least uncertain. With a vi ew accordingly of assuring the penetration of the infiowing 4stream of warmer liquid to all parts ot' the receptacle, as it passes therethrough, I employ a series of baflie plates A, A2 A3, of the form clearly appe-aring from Figs. 5 and 6. `In other Worlds, at each end adjacent to the inlet-and discharge 4openings a a ot the tank, is provided animperf'orate plate A or A2 su's pended from above, so as to leave in effect, an open space a between its'bottoni and lateral kedges, and the tank Walls. Any tendency,A accordingly, at the inlet opening for the Warmer water to rise to the surface and there remain, is effectually overcome, while similarly it is the cooler liquid near the bottom ot the other end of the tank that is withdrawn. The third plate A3 is located midway between the two ends of the tank, being Adisposed so as to contact with the side and bottom of the tank, but is so formed as to leave a lfvertically dispo-sed opening ai* centrally of the tank, so that the divergent streams passing around the battle plate A at the inlet end of the tank, are
` obliged to again unite before they can pass on into the other portion of the tank. Here they are again obliged to diffuse themselves throughout suclrtank portion, before they can escape around the lateral andi bottoml edges lof the remaining baffle plate A2.
From the foregoing description of my improved pasteurizer, it will be obvious that the heating of the contents of such pasteurizer cannot only be conveniently and quickly effected, but automaticallya's well, since the effect of the thermostatic control Will be to admit steam to the' injector until the pasteurizing'temperature has been reached. At the same time, hy reason of the presence and particular disposition of CHRISTINE E.
the batile plates, the heating effect is'uniform throughout the tank, and all-portions will be brought up to such pasteurizing temperatureV at the same time, and likewise maintained at such temperature together, i
so that the reversal of the heating process may be begun with assurance that no part of the receptacles contents has been either over or under-heated. i
Other modes of applying the principle of my vinvention may be employed instead of the one explained, change beine made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 1. A pasteurizer of' the tank type compris-- ing 'a receptacle, means exterior of the same for effecting a circulation of liquid therethrough and simultaneously heating the liquid, and transverse battle plates within said receptacle comprising one at each end spaced from the bottom and sidevsralls'ot-f the receptacle and a centrally located plate in contact with such Walls but'forined with an opening midway between the side walls, whereby the entering warmer liquid is spread throughout the tank.
2. A pasteurizer of the tank type compris ing a Ireceptacle, a conduit exterior of said receptticle and connecting opposite ends of the same,` an injector connected Withsaid conduit adapted to effect a circulation ot` said receptacles contents and simultaneously heat the-same, and transverse battle plates within said receptacle comprising Vone at each end spaced from the bottom and side walls of the receptacle' and a centrally located plate in contact with such walls but formed with an' opening midway between the side- Walls, whereby the entering warmer liquid is spread throughout the tank.
