Abstract

750,027. Sterilizing liquid and semi-liquid substances. CIBOIT, J. J. Dec. 14, 1953 [March 5, 1953], No. 34800/53. Class 49. In apparatus for sterilizing liquid or semiliquid substances, e.g. milk, milk compositions, cream, fruit juice, wherein the substance is injected into a chamber and is therein treated by injected steam, there is provided means actuated by variations of pressure inside the chamber to adjust the steam admission valve thereto and maintain the pressure of saturated steam therein at the value corresponding to the desired temperature of treatment. The apparatus may include a surface heat exchanger to which steam from the sterilizing chamber is fed and through which the substance passes before its injection into this chamber. With the apparatus of Fig. 1, the substance fed through a pipe 2 is injected by an atomizing nozzle 3 into a chamber 1 ; steam is fed by way of a pipe 4 through ports 6 into the chamber ; opening of a steam admission valve 5 in the pipe 4 is adjusted by a diaphragm relay 7 which is in connection by a pipe 8 with the interior of the chamber 1 ; preliminary heating of the substance in the pipe 2 is effected by a heat exchanger 9 fed by way of a duct 10 with steam from the chamber 1. With the apparatus of Fig. 2, the substance fed through a pipe 2<SP>1</SP> is injected by an atomizing nozzle 3<SP>1</SP> into a chamber 1<SP>1</SP>; steam is fed by way of a pipe 4<SP>1</SP> through ports 6<SP>1</SP> into the chamber 1<SP>1</SP>; opening of a steam admission valve 51 in the pipe 41 is adjusted by a relay 7<SP>1</SP> which is in connection by a pipe 8<SP>1</SP> with the interior of the chamber 1<SP>1</SP>; steam-treated substance collecting at the base of the chamber 1<SP>1</SP> is injected through an atomizing nozzle 13 into an expansion chamber 12, and the steam so evolved is led by a duct 14 to a heat exchanger 15 wherein the substance passing through the pipe 2<SP>1</SP> to the chamber 1<SP>1</SP> is heated. With the apparatus of Fig. 3, the substance fed through a pipe 2<SP>1</SP> is injected by an atomizing nozzle 3<SP>1</SP> into a chamber 1<SP>1</SP>; steam is fed by way of a pipe 4<SP>1</SP> through ports 6<SP>1</SP> into the chamber 1<SP>1</SP>; opening of a steam admission valve 5<SP>1</SP> in the pipe 4<SP>1</SP> is adjusted by a relay 7<SP>1</SP> which is in connection by a pipe 8<SP>1</SP> with the interior of the chamber 1<SP>1</SP>; steam-treated substance collecting in the base of the chamber 1<SP>1</SP> is injected through an atomizing nozzle 13 into an expansion chamber 12, and the steam so evolved is led by a duct 14 to a heat exchanger 15 wherein the substance passing through the pipe 2<SP>1</SP> is heated ; the substance passing through the pipe 2<SP>1</SP> is heated further, before reaching the nozzle 3, by a heat exchanger 91 fed by a duct 101 with steam from the chamber 11.
