Abstract
Disclosed is a system for preventing scaling and deposit formation in a sterile air heat exchanger of a system for aseptic packaging within laminated carton packages, and a process for eliminating hydrogen peroxide residues in aseptic laminated carton packaging systems, characterized in that it comprises providing a supply of water for scrubbing sterile air that has the following properties: (a) maximum conductivity at 20° C. of 2.0 micromhos; and (b) a maximum silica content of 0.1 ppm.
Claims16
A system to prevent the formation of incrustations, deposit in a sterile air exchanger in an aseptic packaging system for laminated carton-containing containers, and to remove the residual hydrogen peroxide used in aseptic laminated carton packaging systems, comprising:
- a supply of sterile air wash water having the following properties:
- a maximum conductivity at 20° C. of 2.0 micromhos, and
- a maximum silica content of 0.1 ppm.
A process of residual removal of hydrogen peroxide and recycling sterile air washing water used in an aseptic packaging systems for laminated carton-containing containers, wherein the process is a closed loop system comprising:
- a. providing a fresh sterile air wash water supply that exhibits the following properties:
- a maximum conductivity at 20° C. of 2.0 micromhos, and
- a maximum content of Silica of 0.1 ppm;
- b. feeding the sterile air wash water to a scrubber, for washing the sterile air;
- c. collecting washing water having a content of hydrogen peroxide in a collection tank, at the outlet from an air-water separator coming from the scrubber of the air washing system;
- d. transferring said water to a chiller or heat exchanger, to maintain the water temperature at a suitable value for the operation of the packaging machine;
- e. contacting the water coming from the chiller or exchanger with a filter medium activated carbon, green sand or mixtures thereof in any ratio for the removal of hydrogen peroxide;
- and
- f. obtaining and collecting the fresh sterile air wash water in tank.
A process to modernize an aseptic packaging machine for laminated carton-containing containers, comprising,
- a. installing a tank for a sterile air wash water supply that exhibits the following properties:
- a conductivity at 20° C. of 2.0 micromhos maximum
- an amount of silica being 0.1 ppm maximum;
- b. installing a sterile air wash water supply line to a scrubber, for sterile air wash;
- c. installing a collection tank, to collect washing water with the presence of hydrogen peroxide at the outlet of an air-water separator coming from the scrubber, of an air washing system;
- d. installing a line to transfer the water from tank to a chiller or heat exchanger;
- e. installing a chiller or heat exchanger, at the outlet of the collection tank, to maintain the water temperature at a suitable value for the operation of the packaging machine;
- f. installing a filter medium activated carbon, green sand or mixtures thereof, in any proportion, at the outlet of the chiller or heat exchanger, for the elimination of hydrogen peroxide;
- and
- g. installing a sterile air wash water supply tank.
