ApplicationApril 29, 1931. Serial No. 533,865 3 Claims. (Cl. 175-311) My present invention relates to an improved electrical sterilizing apparatus for destroying bacteria existing in ilowing liquids, and for eliminating the propagation of bacteria lby sterilizing the liquid. In 'carrying out my invention the liquid or fluent material to be treated or sterilized is passed through a container, and while in transit the liquid is subjected to the electrical treatment of an electro-static ux. generated exterior of the container, but passing therethrough, and
'also' through the contents of the container'for the destruction of bacteria that may be contained in the liquid or uent material.
By the utilization of the apparatus of my invention, the liquid, as milk, or other iiuent material,
is passed through a preferably closed container that is fashioned with walls of dielectric material,
which walls and material will permit the transmission of the electrical energy or force without conduction.
For the purpose of passing the electro-static iiux through the container and its contents I utilize a pair of opposed iiux concentrators that are relatively adiustable with respect to the container and located in a secondary circuit, and associated with the primary circuit of a transformer that is connected with a suitable som'ce of high frequency currents of electricity.
The invention consists in certain novel combinations and arrangements of parts as willhereinafter be more fully set forth. In the accompanying drawing I have illustrated one complete example of the physical embodiment of invention wherein the parts are combinedv and arranged according to one mode I have thus far devised for "the practical application of the principles of my invention. v y
Figure 1 is a diagrammatic view of the apparatus of my invention with its electrical connections, showing the movement of the electro-static flux by dotted lines, and indicating the movement of the liquid or iiuent material by arrows.
Figure 2 is a top plan view of the container in which the liquid or uent material is treated as it passes therethrough.
Figure 3 is a sectional view of the closed container.
In thepresent exemplication of my invention I have shown as the container, a ilat cylindrical -vessel 1 having closed top 2 and bottom 3, with an inlet or feed pipe 4 and a discharge or outlet pipe 5, located at diametrically opposite points of the at cylindrical container. The body of the' container, including its top and bottom walls, and the two pipes 4 and 5 adjacent to the container are fashioned of glass or other dielectric material that will permit transmission or passageof the electric energy or flux but without conduction.
Inasmuch as the currents of electrical force have a tendency to pass around the exterior of the vessel, it is desirable that the vessel or container shall be of such diameter or other dimensions as to eliminate this tendencyLand to insure the passage of the electrical current, perpendicularly, through the body of the at cylindrical container, and through the contents of the container.
The liquid, as milk, or other fluent material, is delivered from a suitable source of supply to the container through the feed or inlet pipe, and, aft- 'm er flowing across the interior of the container, is discharged through the outlet or discharge pipe 5 to a suitable receiving vessel.
. The owingliquid is subjected to the electrical treatment by the use of two opposed ilux concentrators or electrodes 6 and 7, preferably located above and below the iiat cylindrical container, and adjustable relatively'to the container to compensate for varying degrees of intensity, and to insure the proper resonance between the two concentrators.
As is well known, the bacteria have afundamental vibrating point, or point of vibrationl at to the life to be destroyed, of the electrical energy discharged which life is destroyed, and I find by actual 35 practice that a voltage of approximately 65,000 volts, operating at approximately 470,000 cycles per second, obtains the best. results in the destruction of the bacteria.
The electrode or flux concentrator 6 is connected by wire 8 to the secondary winding S of a transformer, and the concentrator I is also connected therewith by wire 9 to form a secondary circuit. The primary winding P of the transformer is connected by wires A and C to a suitable source of supply for high frequency electrical energy, as indicated in Figure 1. A
The flow of the electrostatic ilux between the two concentrators 6 and 7 is indicated by m'eans of the dotted lines in Figure l, and it will be apparent that, in passing through the dielectric walls of the flat container, the electrical energy also reaches the liquid or fluent material ilowing through the container, with the result that any living bacteria are destroyed, and subsequent 1 have a fundamental point o f vibration, or point 110 V 1.
