Abstract: A method of sterilizing containers by using a peracetic acid-type sterilizing composition solution, wherein the sterilizing composition solution containing peracetic acid, hydrogen peroxide, acetic acid and catalase as prepared in a circulating tank (1) is heated through a heating unit (3), fed to a sterilizing unit (4), and is recovered in the circulating tank (1) after it is used for the sterilization, wherein the catalase is added to the sterilizing composition solution in a circulating passage of after it was used for the sterilization but before it is fed to the heating unit. This makes it possible to suppress the catalase from losing its activity, to maintain the sterilizing power of the sterilizing composition solution, and to use the sterilizing composition solution in a circulating manner without cooling it saving, therefore, the heat energy providing advantage in economy.

Abstract: A peracetic acid type sterilizing composition solution containing peracetic acid, acetic acid, hydrogen peroxide and catalase enzyme, wherein said sterilizing solution has a pH in a range of 2.6 to 5.0, said catalase enzyme is contained in an amount of 0.1 to 10 ?g/ml, the concentration of said peracetic acid is 500 to 10,000 ppm, and the concentration of said hydrogen peroxide is less than 500 ppm. The concentration of the hydrogen peroxide can be efficiently decreased due to the catalase enzyme that is added in small amounts thereby suppressing the bubbling caused by the addition of the catalase enzyme.

A non-inserted nozzle 20 is disposed at a distance of 1-50 mm below the lower end surface 52 of a mouth of a container conveyed in an inverted posture, the sterilizing fluid is mixed with air and the sterilizing fluid is atomized and sprayed intermittently from the non-inserted nozzle toward the inside of the container.

Abstract: A non-inserted nozzle for washing a container that can increase the washing efficiency, decrease the amount of washing fluid used, and shorten the washing time in sterilizing and washing a bottle container. The upper end surface of a non-inserted nozzle 8 serves as a liquid-receiving surface 10, and a retention wall 11 of a predetermined height is formed on the outer periphery of the liquid-receiving surface, thereby producing a retention recess. A plurality of nozzle holes 13 linked to a fluid channel of a nozzle stem 14 are provided obliquely so as to spread outwardly substantially in the central section of the liquid-receiving surface. The non-inserted nozzle 8 is disposed below the mouth of an inverted container 28 at a distance H from it and the sterilizing fluid or washing fluid is sprayed from below the mouth of the container, without inserting the nozzle into the container.

Abstract: A method for sterilizing a plastic bottle in an aseptic filling system according to which at least an inner surface or an outer surface of a bottle is sterilized by injecting a heated sterilizing fluid at 65° C.-90° C. while maintaining internal pressure of the bottle at 1 kPa-20 kPa.

Abstract: The present invention provides an aqueous solution of a sterilant of peracetic acid series for use in aseptic filling comprised predominantly of hydrogen peroxide, peracetic acid and water wherein a pH of the aqueous solution is 2˜4, a ratio of the concentration of hydrogen peroxide/the concentration of peracetic acid is 0.7 or less, and the concentration of peracetic acid is 500˜3000 ppm as well as a sterilization method wherein the sterilant thereof is used. The sterilant of peracetic acid series exhibits an excellent sterilizing effect even at an extremely low concentration of peracetic acid and so is economically advantageous. What is more, washing of the sterilant with sterile water after sterilization of a container is attained by injecting sterile water even for a short period of time to such level that the sterilized container can be filled with foods and drinks, so that the sterilant is remarkable in economical value and working efficiency.
