- the invention relates to a plant according to the preamble of claim 1 and in particular to a plant with a cleaning and rinsing system for rinsing and cleaning plant components and connections between plant components, i. in particular for cleaning and rinsing product-carrying spaces and channels of the system components and of product-carrying lines between these components even in a CIP cleaning and rinsing mode or operation.
- the invention further relates to a method according to the preamble 18.
- Cleaning and rinsing systems in particular also for cleaning installations for providing, processing and filling of liquid products, preferably of beverages in bottles or in other containers, are known.
- the known systems are basically designed in such a way that, during the respective cleaning and rinsing operation, all the system components with their areas to be cleaned as well as the product-carrying connections and lines between the system components are arranged in series and thus a single one of the respective cleaning system. and flushing medium flow through CIP circuit.
- This training has the consequence that each volume element of the cleaning or flushing media is inevitably passed through all system components and all connections and lines.
- cleaning and rinsing media are used during the cleaning and rinsing operation, namely, for example hot water, acid, lye and fresh water, as is generally customary, the system components arranged in series in the CIP cycle are timed successively with these cleaning agents. and rinsing media treated.
- the duration of treatment is thus usually determined by the treatment time of the container filling machine, since this must be cleaned very intensively due to its numerous small and angular fluid channels and the same valve arrangements, which is usually achieved by a long treatment time.
- Plant components within the meaning of the invention are basically all components or devices of a plant for which cleaning and / or rinsing is required, in particular those components or devices which are used to provide, processing and / or processing the respective product during normal operation of the plant

- it may be expedient to control the flow of the cleaning and rinsing medium by appropriate control of control valves provided in the mixer 20. in order to achieve optimum treatment of all components, in particular all the product-carrying components of the mixer 20.
- Appendix 1 b is particularly suitable for bottling CSD beverages, i. of carbonated soft drinks.
- the product accommodated in the buffer memory 7 or 23 is a product containing carbonic acid, which is kept under pressure in the buffer during filling operation with the aid of a CO2 gas buffer, the cleaning and purging of the buffer memory 7 or 23 takes place without the Use of lye. Instead, acid is used in the cleaning and rinsing instead of alkali in order to avoid a dangerous overpressure, which destroys the buffer memory 7 or 23 and thus the system 1, 1a and 1b, even without gas exchange.
- the embodiment according to the invention makes it possible to treat other plant components which do not contain CO2 gas at the same time or overlapping in time with caustic.
