Apparatus for continuous, automatic sterilization of fluid in sealed containers

Claim 1

An apparatus for sterilization of fluid of sealed containers, comprising a chamber substantially hermetically sealed and having a supply point at one part of said chamber at which is a supply opening in said chamber land having a removal point at another part of said chamber spaced from said supply point and at which is a removal opening, means for supply of containers to be treated extending from the outside of said chamber to the supply point through the supply opening of the chamber, means for removal of treated containers extending from the removal point to the outside of the chamber through the removal opening of the chamber, drum mounted to be rotatable about its vertical axis in said chamber having compartment defining means thereon defining a plurality of vertically stacked tiers of compartments for accommodation and transport of containers to be treated, said chamber having a plurality of bottom walls fixedly mounted therein one being associated with each tier of compartments and constituting the bottoms of said compartments, each bottom wall having a gap therein, the gaps being at different circumferential positions, the gaps being for transferring containers inserted and carried in compartments automatically one after the other to the next adjacent lower tier at said positions, means in said chamber for heating air and circulating the heated air in the chamber, each compartment having aperture means therein for permitting passage of the circulating hot air laterally therethrough in a direction transverse to the direction of transport of the containers for sterilizing the fluid contained in the containers, and drive means connected to said conveyor for continuously driving the conveyor to carry the containers within the compartments from the supply point to the removal point, said drive means, supply means and removal means being coupled for synchronous driving.

Claim 2

An apparatus for sterilization of fluid of sealed containers, comprising a chamber substantially hermetically sealed and having a supply point at one part of said chamber at which is a supply opening in said chamber land having a removal point at another part of said chamber spaced from said supply point and at which is a removal opening, means for supply of containers to be treated extending from the outside of said chamber to the supply point through the supply opening of the chamber, means for removal of treated containers extending from the removal point to the outside of the chamber through the removal opening of the chamber, drum mounted to be rotatable about its vertical axis in said chamber having compartment defining means thereon defining a plurality of vertically stacked tiers of compartments for accommodation and transport of containers to be treated, said chamber having a plurality of bottom walls fixedly mounted therein one being associated with each tier of compartments and constituting the bottoms of said compartments, each bottom wall having a gap therein, the gaps being at different circumferential positions, the gaps being for transferring containers inserted and carried in compartments automatically one after the other to the next adjacent lower tier at said positions, means in said chamber for heating air and circulating the heated air in the chamber, each compartment having aperture means therein for permitting passage of the circulating hot air laterally therethrough in a direction transverse to the direction of transport of the containers for sterilizing the fluid contained in the containers, and drive means connected to said conveyor for continuously driving the conveyor to carry the containers within the compartments from the supply point to the removal point, said drive means, supply means and removal means being coupled for synchronous driving.

Claim 6

An apparatus for sterilization of fluid in sealed containers, comprising a chamber substantially hermetically sealed and having a supply point at one part of said chamber at which is a supply opening in said chamber and having a removal point at another part of said chamber spaced from said supply point at which is a removal opening, means for supply of containers to be treated extending from the outside of said chamber to the supply point through the supply opening of the chamber, means for removal of treated containers extending from the removal point to the otuisde of the chamber through the removal opening of the chamber, a magazine conveyor in said chamber constituted by a cylindrical drum means, a means rotatably mounting said drum within the said chamber, a plurality of partitition plates disposed at equal intervals around the outer periphery of the drum and extending radially outwardly therefrom, a plurality of baseboards fixedly mounted in position within said chamber in planes transverse to the axis of said drum at intervals along said drum axis, said partition plate shaving slots therein in a direction transverse to the axis of the drum and into which said baseboards extend in slidable relationship, said partition plates and baseboards and the outer peripheral surface of the drum constituting vertically stacked tiers of compartments for carrying containers, and each baseboard having a gap therein for passing a container therethrough to the next adjacent lower tier, one portion of the periphery of the drum being at the supply point and another portion of the periphery of the drum being at the removal point, means in said chamber for heating air and circulating the heated air in the chamber, the wall of the drum in each compartment having at least one aperture therein for permitting passage of the circulating hot air laterally therethrough in a direction transverse to the direction of transport of the containers for sterilizing the fluid contained in the containers, and said rotatable mounting means includes drive means for continuously rotating the drum to carry the containers within the compartments from the supply point to the removal point, said drive means, supply means and removal means being coupled for synchronous driving.

Claim 7

An apparatus for sterilization of fluid in sealed containers, comprising a chamber substantially hermetically sealed and having a supply point at one part of said chamber at which is a supply opening in said chamber and having a removal point at another part of said chamber spaced from said supply point at which is a removal opening, means for supply of containers to be treated extending from the outside of said chamber to the supply point through the supply opening of the chamber, means for removal of treated containers extending from the removal point to the otuisde of the chamber through the removal opening of the chamber, a magazine conveyor in said chamber constituted by a cylindrical drum means, a means rotatably mounting said drum within the said chamber, a plurality of partitition plates disposed at equal intervals around the outer periphery of the drum and extending radially outwardly therefrom, a plurality of baseboards fixedly mounted in position within said chamber in planes transverse to the axis of said drum at intervals along said drum axis, said partition plate shaving slots therein in a direction transverse to the axis of the drum and into which said baseboards extend in slidable relationship, said partition plates and baseboards and the outer peripheral surface of the drum constituting vertically stacked tiers of compartments for carrying containers, and each baseboard having a gap therein for passing a container therethrough to the next adjacent lower tier, one portion of the periphery of the drum being at the supply point and another portion of the periphery of the drum being at the removal point, means in said chamber for heating air and circulating the heated air in the chamber, the wall of the drum in each compartment having at least one aperture therein for permitting passage of the circulating hot air laterally therethrough in a direction transverse to the direction of transport of the containers for sterilizing the fluid contained in the containers, and said rotatable mounting means includes drive means for continuously rotating the drum to carry the containers within the compartments from the supply point to the removal point, said drive means, supply means and removal means being coupled for synchronous driving.
