Definitions
- the invention relates to a method and an apparatus for evacuating a Protective gas-fillable chamber, in particular a sealing chamber of a packaging machine, as for the packaging of meat and sausage products is used.
- Carbon dioxide CO 2
- Nitrogen N 2
- gas mixtures of these two components are often used in different compositions.
- the fresh meat packaging under a protective atmosphere with oxygen content is another Procedure that compared to the pure vacuum packaging and the o.g. packaging under inert atmosphere (nitrogen) or nitrogen / carbon dioxide mixtures increasingly important.
- An infeed conveyor clocks the machine through a set of trays fed.
- the number of trays per batch depends on the capacity a seal chamber in which the trays are evacuated.
- the insertion of the to be packed Product is done manually by staff next to the inlet line.
- To Loading the product the batch is transported in the seal chamber.
- From a above the sealing chamber arranged film roll is the top film guided over the shells.
- Two chamber halves (upper and lower tool) are pneumatically closed.
- the sealing chamber is pre-evacuated to a certain pressure. This is followed by the back-venting of the sealing chamber with inert gas up to Atmospheric pressure. Even during the gassing process, the top film on the dish is sealed and punched out.
- After opening a ventilation valve for pressure equalization with the environment the chamber tool is opened and the Trays are transported to the outlet conveyor of the machine. There is a statistical Monitoring of gas composition by sampling (not non-destructive).
- Disposal of the air in the shells before fumigation (evacuation) can basically be done by different process techniques.

- a buffer valve 250 for shutting off the buffer volume lead 251 provided.
- a first Bottom film or a dish with the goods to be packaged and a top film in the opened seal chamber 204 introduced.
- the seal chamber 204 becomes airtight closed, wherein the chamber valve 206, the protective gas valve 212 and the Ventilation valve 213 are initially closed.
- the chamber valve 206 and the buffer valve 250 opened, the buffer volume 249 still has been evacuated from a previous procedure clock. It thus finds a pressure balance between the sealing chamber 204 and the buffer volume 249 instead.
- the buffer valve 250 is closed and the vacuum valve 241 is closed while the vacuum pump is running 245, so that the sealing chamber 204 by means of the vacuum pump 245 is further evacuated.
- the effluent from the sealing chamber 204 Gas is continuously analyzed with the sensor 246 to immediately increase the oxygen concentration to investigate.
- the pressure over time is in the form of an exponential function, i.
- the pressure drops quickly and further Evacuation progressively slower. Due to the initial pressure equalization between the buffer volume 249 and the sealing chamber 204 was thus initially ensures a rapid pressure drop, the buffer volume 249 that from the Seal chamber 204 caching escaping gas, without it to the vacuum pump 245 to promote.
- the buffer volume 249 that from the Seal chamber 204 caching escaping gas, without it to the vacuum pump 245 to promote.
- the further evacuation by means of the vacuum pump 245 already begins at a low pressure, so no major pressure fluctuations occur and a slow evacuation takes place.
- the pressure fluctuations are significantly lower than initially, so that the sensor 246 can continuously provide reliable values stop the vacuum pump 245 early enough or close the vacuum valve 241.
- the chamber valve 206 After evacuating the seal chamber 204, the chamber valve 206 is closed, whereupon the sealing chamber 204 as in the aforementioned embodiments filled with protective gas and then aerated. During that, that will be Check valve 250 is opened, so that the buffer volume 249 also by means of the vacuum pump 245 is evacuated with open vacuum valve 241. As the pressure in the Buffer volume 249 is also lower and the pressure in the seal chamber 204th after pressure equalization between the buffer volume 249 and the seal chamber 204 corresponds, also find no large pressure fluctuations during evacuation of the buffer volume 249 with the vacuum pump 245, so that the sensor 246 continuously provides reliable values to shut off the vacuum pump 245 early enough or to close the vacuum valve 241 soon enough Gas with excessive oxygen concentration reaches the vacuum pump 245. Thus, the buffer volume 249 is again sufficiently pre-evacuated to after the closing of the vacuum valve 241 again with the seal chamber 204 in the next Process cycle to be connected for pressure equalization.
