Abstract
Abstract A vacuum deaerator including an enclosed, evacuated housing having an inlet at the upper end thereof and an outlet at the lower end. The deaerator includes a series of plate assemblies mounted within the housing in superposed relationship, as follows: a first, heating assembly mounted immediately below the inlet to heat incoming liquid to a predetermined temperature; a second assembly which receives the heated liquid from the first assembly to expose said liquid to the vacuum established within the housing and thereby thoroughly deaerating said liquid; and a third, cooling assembly disposed beneath the second assembly which receives the deaerated liquid and cools same to a predetermined temperature in preparation for carbonation of said liquid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
Deaerating apparatus comprising: an enclosed housing; means for removing air from said housing to provide an evacuated atmosphere therein; an inlet connected to said housing through which water to be deaerated enters said housing, and an outlet for removing deaerated water from said housing; a first, heated plate assembly disposed immediately below said inlet over which said water is flowed to raise its temperature to a predetermined value; a second plate assembly disposed immediately below said first plate assembly and adapted to have the heated water flowed thereover to subject said water to the evacuated atmosphere thereby thoroughly deaerating said water; and a third, cooled plate assembly disposed below said second plate assembly over which said deaerated water is flowed to lower it to a predetermined temperature, such that said water to be deaerated is subjected to the evacuated atmosphere within the housing during the entire time it is flowing over the plate assemblies.
Claim 2
Dependent Claim
154 words
Deaerating apparatus comprising: an enclosed housing; means for removing air from said housing to provide an evacuated atmosphere therein; an inlet connected to said housing through which water to be deaerated enters said housing, and an outlet for removing deaerated water from said housing; a first, heated plate assembly disposed immediately below said inlet over which said water is flowed to raise its temperature to a predetermined value; a second plate assembly disposed immediately below said first plate assembly and adapted to have the heated water flowed thereover to subject said water to the evacuated atmosphere thereby thoroughly deaerating said water; and a third, cooled plate assembly disposed below said second plate assembly over which said deaerated water is flowed to lower it to a predetermined temperature, such that said water to be deaerated is subjected to the evacuated atmosphere within the housing during the entire time it is flowing over the plate assemblies.
Claim 3
Dependent Claim
95 words
Deaerating apparatus as defined in claim 1, further including; a first trough having a perforated base wall and being disposed within said housing immediately above said first, heated plate assembly for accumulating water entering said inlet and distributing said water through said apertures over said first plate assembly; a second trough having a perforated base wall disposed immediately below said first plate assembly for accumulating heated water and distributing same to said second plate assembly; and a third perforated trough disposed intermediate the second and third plate assemblies for distributing water to said third assembly.
