Abstract
Abstract In the pasteurizing of beverages in closed containers, the containers arrive generally in a chilled state and are progressively raised in temperature approaching the pasteurizing temperature and, after being pasteurized for an appropriate time, are progressively cooled down. Apparatus of this type is provided with a source of chilled water which is available for use when skips occur in the supply of the containers, the chilled water being accumulated from the incoming containers and from common outside sources. The accumulated water in its chilled state saves substantial amounts of energy by eliminating mechanical or other means to produce the chill effect, and such source of water is constantly available under control which senses the presence of a skip in the supply of containers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A process for conserving the use of water in a pasteurizer for moving initially cold containers through successive preheating zones where the containers are raised in temperature and give up the cold temperature values and through precooling zones where the containers are lowered in temperature from a pasteurizing temperature by giving up heat, the process comprising: providing a cooled water containing compartment in advance of the movement of the initially cold containers into the preheating zones and showering the cooled water over the cold containers to acquire the cooling values therefrom while raising the temperature thereof, and making the cooled water from the water containing compartment available initially for use in the precooling zones to acquire heat therefrom imparted to the containers passing out of the pasteurizing zone when a skip occurs in the movement of containers in the preheating zones.
Claim 2
Dependent Claim
141 words
A process for conserving the use of water in a pasteurizer for moving initially cold containers through successive preheating zones where the containers are raised in temperature and give up the cold temperature values and through precooling zones where the containers are lowered in temperature from a pasteurizing temperature by giving up heat, the process comprising: providing a cooled water containing compartment in advance of the movement of the initially cold containers into the preheating zones and showering the cooled water over the cold containers to acquire the cooling values therefrom while raising the temperature thereof, and making the cooled water from the water containing compartment available initially for use in the precooling zones to acquire heat therefrom imparted to the containers passing out of the pasteurizing zone when a skip occurs in the movement of containers in the preheating zones.
Claim 3
Independent Claim
188 words
A method of operating a pasteurizer having a conveyor for transporting initially cold containers from an inlet through a series of temperature increasing zones, a pasteurizing zone, and a series of temperature decreasing zones, to an outlet, the method comprising: establishing a first series of zones for delivering liquid upon containers for increasing the temperature toward a pasteurizing temperature; establishing a second series of zones for delivering a liquid upon containers for decreasing the temperature thereof after pasteurization; connecting a source of chilled liquid with the first series of zones; establishing a source of heated liquid through fluid connection with the pasteurizing zone and with certain of said second series of zones; establishing a zone of auxiliary liquid adjacent the inlet for absorbing the cooling values from the initially cold containers and initially lifting the temperature thereof; and controlling the use of the auxiliary liquid, the chilled liquid and the source of heated liquid in a predetermined sequence for accommodating the presence of a skipper arising in the first series of zones and moved by the conveyor into and through the second series of zones to the outlet.
Claim 4
Independent Claim
188 words
A method of operating a pasteurizer having a conveyor for transporting initially cold containers from an inlet through a series of temperature increasing zones, a pasteurizing zone, and a series of temperature decreasing zones, to an outlet, the method comprising: establishing a first series of zones for delivering liquid upon containers for increasing the temperature toward a pasteurizing temperature; establishing a second series of zones for delivering a liquid upon containers for decreasing the temperature thereof after pasteurization; connecting a source of chilled liquid with the first series of zones; establishing a source of heated liquid through fluid connection with the pasteurizing zone and with certain of said second series of zones; establishing a zone of auxiliary liquid adjacent the inlet for absorbing the cooling values from the initially cold containers and initially lifting the temperature thereof; and controlling the use of the auxiliary liquid, the chilled liquid and the source of heated liquid in a predetermined sequence for accommodating the presence of a skipper arising in the first series of zones and moved by the conveyor into and through the second series of zones to the outlet.
Claim 5
Dependent Claim
80 words
The method set forth in claim 2, wherein the predetermined sequence of control is such that the presence of a skipper effects introduction of the auxiliary liquid through the first zones without contacting the containers in such zones and into the second zones for contact with the containers to acquire the heat of pasteurization, followed by the introduction of the now heated liquid from the second zones into the first zones to effect preheating of the containers by contact therewith.
