PASTEURIZING APPARATUS.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed June 27, 1907. Serial No. 381,022.

b all tU/towl 'it may concern:

Be it known that; l. Ctuumis ll. Lontv, a citizen oi the linitet' States, residing at Lakewood. in the county of (luyahoo'a and State of Ohio, have invented certain new and use 'l'ul lmprovenients in lasteurizing Appza ratus, ot which the following is a specification.

My invention relates to a pasteurizing apparatus and more particularly to anapparatus designed to be employed in thepasteurimtion of beer in bottles. and its novelty consists in the construction and adaptation ol the parts as will he more fully hereinafter pointed out.

In the drawingthere is represented somewhat in diagrammatic form a vertical medial section and partial side elevation of a pasteurizer embodying my invention.

in the drawings 10 is a tank made of steel iron, or other suitable material, and divided into two portions. namely, a lower portion 11 comprising a pasteurizing chamber and an upper portion l3 comprising what I. call an interchanging chamber, for the reasons hereinafter set' forth. The pasteurizing chamber is supplied with suitable inlet ports indicated at 12 to: the admission of steam or hot Water theretoand with an overflow port indicated at 13. so that the water introduced into the chamber cannot rise above a certain level. It will he noted that the chamber 11 has no communication Withthc outer air.

The interchanging chamber 12 is arran ed immediately above the pasteurizingcham 1' over which it is centrally placed. It is closed at the top and is provided laterally 'With an opening 14 for the reception of the bottles to be pasteurized and a similar opening 15 on the other side for the discharge of the bottles after they have been pasteurized.

16, 16, indicate shelves projecti from the side Walls of the interchanging :iliamber for the convenience of the workmen in resting the bottle boxes thereon.

17 indicates a flooring and 1% a ceiling for a room in which the bottles are received and discharged from the apparatus, the pasteurizing chamber ll'being lace'd beneath the floor and the driving moo anism for the conveyor (hereinafter referred to) beinl placed above the ceilinglor on the floor of t e story above.

Centrally arranged within. the apparatus is an endless conveyor 20 made of any usual construction and.comprising holders or retake them therefrom.

ceptacles 21 flexibly connected to chains 22 of which the convcyer is in part formed, so that. the receptacles 2t maintain by gravity substantially the same relative position in their travel through the a 'iparatus. --This conveycr is suitably supported upon roller supports placed at pro )er intervals throughout the apparatus an is propelled by a sprocket wheel 24, or other suitable device receiving power from a train of gearing 25 and which train of gearing includes a (ieneva wheel i whereby an intermittent motion is imparted to the conveyer.

Ar 'anged within the pasteurizing ehaluher and above the water level thereof is a shallow tank or water collector within which is placed a centrifugal pump 31. or other suitable form of water lifting device, and which is connected by a pipe 32 to a reservoir 33 placed within the conveyor 20 and practically opposite the receiving and discharging apertures H and 15. The reservoir is provided with substantially vertical walls and the receptacles 21 of the endless conveyor 20 as they pass by such walls inaytouch the same if they are swung upon the pivots upon which they are hung by the ohains 520 so that these walls serve as a guard to prevent any displacement of the reeepta. class which would render it ditlicult or inconvenient to place the bottle boxes thereon or A sprinkling device 36 of usual form is secured to the reservoir 33 and receiving the water therefrom is ada ted to spray it downwardly upon the bott e receptacles as they pass by the same.

Inusin this apparatus the chamber 11 is first fille with Water up to the level controlled by the position. of the outlet pipe til and this water may either be preheated in a separate receptacle or may be heated by the admission of steam through the pipes 12.

'VVhichever method is employed it should be heated to a pasteurizing temperature sufficient to kill the germs in the beer or other liquid in the receptacles intended to be passed through the same. ater is then placed in the collector 30. This water is preferably of a temperature intermediat that of the water in the pasteurizing l l)ttll1'- her 11 and the outer air. The conveyer 30 is then started and the pump ll is siu'iilarly started. The workmen then place the. boxes containing the bottles of beer to he pasteui ized upon the receptacles Al they pass the receiving aperture 14 and such bottles are till gradually brought past the sprinkling device :56 they are subjected to the action of a spray of water derived from the water collector 30 and which water warmer than the outer air with which they have previously been brought into contact and is cooler than the water in the pasteurizing chamber 11. As.

the recc 'it'acles 20 pass downward the bottles are subjected to a constantly increasing heat derived from the vapors arising from the hot water in the chamber 11 until finally they pass into the water bath at the bottom of that chamber at a temperature substantially identical therewith. As therecepta cles 2t) emerge from the water bath and pass upward into the interchanging chamber they part with a portion of their heat and finally when they reach a proper location they are subjected to the action of the spraying device 2313 which cools them to the temperature of the water contained in the colh-rtor ll) or a little below that temperature and they are then in a condition to be removed from the apparatus without danger of breaking when brought into contact with the temperature of the outer air.

It will he noted that my apparatus is simple in construction. It comprises few parts and those made of common standard materials. It involves the use of but one pasteurizing chamber and it employs the heat radiated from the surface of the water in that pasteurizing chamber to raise the temperature of the water in the sprinkling device, so that the modifications of temperature of the bottles slowly and gradually and without danger of their breaking. It will be noted also that there are no valves or trap doors in the apparatus and very little loss of heat from direct radiation by its use, and that by means of the construction described, I subject the liquids to be pasteurized to the action of heating and cooling mediums of diiferent; temperatures with respect to such liquids but. all of which different temperatures are t'lerived from the same source of heat and without any loss.

A )asteurizing apparatus, comprising a pasteurizing chamber, an interchanging chamber directly above the same and open to receive heated vapors therefrom, a spraying device located in said interchanging chamber, a water collector located within the pasteurizing chamber above and close to the water line and adapted to receive the water discharged from the spraying device so that it may be heated while in the collector from the heat in the pasteurizing chamber and means for forcing the water from the water collector to the spraying device.
