And can also have a set of ports 376 with one or more ports.
The pasteurization station can include one or more modules 364. Each module 364 has flow passages 378,380,382 and can also have flow passages 384,386. As shown in FIG. 6, during the first mode of the pasteurization cycle, steam is introduced through the flow passage 378 and flows through the ports 354,372 into the respective chambers 304,366. Furthermore, it is exhausted through the respective flow passages 380 and 382 after passing through the respective ports 356 and 374. It can also be additionally and alternately exhausted through the respective ports 360,376 and through the respective flow passages 384,386. The liquid compressed from the vapor is discharged through the respective ports 356,374 and through the respective passages 380,382.
During the second mode of the pasteurization cycle shown in FIG. 7, steam is introduced through the flow passages 384,386, further flows from the respective ports 360,376 into the respective chambers 304,366, and through the respective ports 356,374, respectively. Exhausted via 380 and 382. In addition, the air can be additionally or alternately exhausted through the flow passages 378 through the ports 354 and 372. When the pasteurization is complete, the packaging advances and is closed at the closing station 26 using the upper web 25 as in Patent Document 1 above.
It will be acknowledged that various equivalents are possible within the appended claims and that modifications and amendments are possible. The term pasteurization is used herein according to the definition found in general dictionaries and includes the partial sterilization of a substance by temperature treatment for a given exposure time, thereby the chemistry of the substance. Destroy unwanted organic matter without causing change. It also includes the destruction of pathogenic and / or putrefactive organic matter in order to extend the packaging life.
The present invention can use a variety of conventionally known web wrapping machines, including continuously operating web wrapping machines and indexed web wrapping machines. The present invention is not limited to a specific number, but it is desirable that a plurality of packages of food can be processed at the same time in the pasteurization stations shown in FIGS. 8 to 10. That is, the present invention includes pasteurization in one or more food packages. In addition, additional pasteurization stations can be further provided, with each pasteurization station having one or more pasteurization chambers. The food reversal is preferably carried out, for example, via the foam inverter 308. This inversion is not always necessary and can be omitted if desired. The pasteurization medium is preferably steam and may instead be heated air or superheated steam. Other forms of pasteurization medium can also be used.
