Abstract
Abstract Apparatus for treating a liquid with a gas, in particular for deodorizing edible oil, comprises a vessel, pipe lines for introducing into the vessel a certain quantity of liquid to be treated and for discharging treated liquid from the vessel and a vertically extending chimney open at its bottom and top ends and positioned in the vessel with its bottom end near the bottom of the vessel and its top end extending above the liquid level in the vessel. A steam injector discharges into the chimney to heat the liquid and produce strong upward flow of liquid in the chimney. By a deflecting baffle spaced above the top of the chimney and having a diameter greater than the chimney, the liquid discharged from the top of the chimney is directed outwardly and downwardly over the surface of liquid in the vessel. The chimney preferably has a hollow wall in which a temperature fluid is circulated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
293 words
An apparatus for processing a liquid by means of a gas, notably for deodorizing edible oil, comprising a vessel for containing said liquid, said vessel being connected to a source of vacuum, pipe line means for introducing liquid into said vessel to fill said vessel to a selected liquid level and means for discharging processed liquid from said vessel, at least one vertically extending chimney open at its bottom and top ends and centrally positioned in said vessel and extending upwardly from near the bottom of said vessel to above said liquid level, said chimney having a cross sectional area which is a minor part of the cross sectional area of said vessel, said chimney comprising a hollow wall, said hollow wall formed by a plurality of coaxial turns of coiled tubing, said tubing having a circular cross section and said turns in abutting relation to one another, means connected to said tubing at the bottom of said chimney for supplying to and circulating in said hollow wall to said top of said chimney a fluid at a temperature other than that of said liquid whereby said hollow wall constitutes heat transfer means, at least one steam injector immersed in said liquid and discharging in said chimney to produce upward flow of liquid in said chimney, said liquid being drawn into the bottom end of said chimney and discharged from the top end of said chimney, and deflecting baffle means spaced above the top end of said chimney, said baffle means being of a diameter substantially greater than said chimney and having a peripheral surface portion which extends radially outwardly beyond said chimney and is directed outwardly and downwardly to direct outwardly and downwardly liquid discharged from the top end of said chimney.
Claim 2

293 words
An apparatus for processing a liquid by means of a gas, notably for deodorizing edible oil, comprising a vessel for containing said liquid, said vessel being connected to a source of vacuum, pipe line means for introducing liquid into said vessel to fill said vessel to a selected liquid level and means for discharging processed liquid from said vessel, at least one vertically extending chimney open at its bottom and top ends and centrally positioned in said vessel and extending upwardly from near the bottom of said vessel to above said liquid level, said chimney having a cross sectional area which is a minor part of the cross sectional area of said vessel, said chimney comprising a hollow wall, said hollow wall formed by a plurality of coaxial turns of coiled tubing, said tubing having a circular cross section and said turns in abutting relation to one another, means connected to said tubing at the bottom of said chimney for supplying to and circulating in said hollow wall to said top of said chimney a fluid at a temperature other than that of said liquid whereby said hollow wall constitutes heat transfer means, at least one steam injector immersed in said liquid and discharging in said chimney to produce upward flow of liquid in said chimney, said liquid being drawn into the bottom end of said chimney and discharged from the top end of said chimney, and deflecting baffle means spaced above the top end of said chimney, said baffle means being of a diameter substantially greater than said chimney and having a peripheral surface portion which extends radially outwardly beyond said chimney and is directed outwardly and downwardly to direct outwardly and downwardly liquid discharged from the top end of said chimney.
Claim 3
Dependent Claim
35 words
An apparatus as set forth in claim 1 wherein the top portion of said chimney emerges above the liquid level by a height ranging from one-tenth to one-twentieth of the total height of said chimney.
Claim 4
Dependent Claim
29 words
An apparatus as set forth in claim 1, wherein the inner diameter of said chimney ranges from about one-third to about one-fourth of the inner diameter of said vessel.
