Problems solved by technology

In order to obtain aseptic products by sending out liquid products at room temperature, the process must be carried out in a sterile environment gas, which is expensive, and there is often a danger of bacterial contamination breaking through the protective parts during operation and contaminating the product. Therefore, normal temperature filling Insufficient sterility

Embodiment approach 1

[0065] according to figure 1 The outline of the aseptic filling machine will be described below. The aseptic filling machine includes: a preheating sterilization unit 6 for sterilizing preforms 1 supplied from a preform supply device 3; and a heating unit 14 for sterilizing preforms 1 . The preform 1 is heated to the temperature of forming a bottle 2; the forming filling part 21 molds the heated preform 1 into a bottle 2 and fills the content at the same time; and the sealing part 26 controls the filled content. Seal the bottle 2 of the product, and further illustrate the details of the aseptic filling machine and the aseptic filling method according to the accompanying drawings. According to Embodiment 1, the contents can be filled while the sterilized preform 1 is being molded, and an aseptic product filled with the contents can be obtained through fewer steps than before.

Embodiment approach 2

[0165] First, according to Figure 14The outline of the aseptic filling machine according to Embodiment 2 will be described. The aseptic filling machine includes a heating unit 14 that heats the preform 1 supplied from the preform supply device 3 to a temperature at which a bottle 2 is formed. The sterilizing section 82 after heating sterilizes the heated preform 1; the molding filling section 21 fills the sterilized preform 1 with high-pressure filling to form the preform into The bottle 2 is filled with the content at the same time; and the sealing part 26 is used to seal the bottle 2 filled with the content. According to Embodiment 2, the sterilized preform 1 can be molded and the contents can be filled at the same time, and an aseptic product filled with the contents in the bottle 2 can be obtained with fewer steps than before.

Embodiment approach 3

[0182] First, according to Figure 15 The outline of the aseptic filling machine according to Embodiment 3 will be described, and the differences from Embodiment 1 or Embodiment 2 will be further described. This aseptic filling machine includes: The preform 1 supplied by the product supply device 3 is sterilized; the heating unit 14 heats the sterilized preform 1 to the temperature at which the bottle 2 is formed; the heated sterilization unit 82 sterilizes the heated preform 1 The forming filling part 21 is used to fill the sterilized content into the sterilized preform 1 under high pressure, so that the preform 1 is molded into a bottle 2 and filled with the content at the same time; and the sealing part 26 is used to The bottle 2 filled with the contents is sealed. According to Embodiment 3, since the preform 1 is sterilized before heating the preform 1, the sterilization after heating can be easily performed, and the temperature drop of the preform 1 after heating can be ...

Abstract

The purpose of the present invention is to provide an aseptic filling machine and an aseptic filling method with which a facility can be reduced in size to hold down an initial investment, a process can be simplified to enable a reduction in running cost, and molding and filling can be performed at the same time in reliable and aseptic state. The aseptic filling machine comprises: a preheat sterilizing section that sterilizes a preform; a heating section that heats the sterilized preform; a molding filling section that performs molding into a bottle and filling of contents at the same time byfilling the heated preform with the contents sterilized at high pressure; and a sealing section that seals the bottle filled with the contents. The respective sections are sterilized before an operation of the aseptic filling machine, and aseptic air is supplied to the respective sections to maintain aseptic state during the operation of the aseptic filling machine.

Description

technical field [0001] The present invention relates to an aseptic filling machine and an aseptic filling method for sterilizing a preform, molding the sterilized preform in an aseptic environment gas, and simultaneously filling contents. Background technique [0002] Tea, sports drinks, milk drinks, fruit juice drinks, and the like are mainly filled in biaxially stretched polyethylene terephthalate (PET) bottles and distributed. If these beverages are filled with bacteria, etc., there is a risk of spoilage. Therefore, the sterilized beverages are filled into sterilized bottles in an aseptic atmosphere and sealed with a sterilized cap. The process is carried out continuously from the preform into the bottle to the sealing by an aseptic filling machine. [0003] As such an aseptic filling machine, an inline system has been proposed in which a sterilizing agent such as hydrogen peroxide is sprayed on the preform while conveying the preform, and then the preform is heated to s...
