Description

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. especially for cleaning and rinsing product-carrying spaces and ducts of the system components and of product-carrying lines between these components also 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.

A simple plant for the purification of individual components of such a plant was by the DE 1 557 552 In detail, this document provides for cleaning the individual components of such a system individually and then, when the cleaning of one component is completed, to begin with the cleaning of the next component. According to the DE 1 557 552 It is essential that the intended ring line to avoid blind spaces is always completely flowed through. The proposed by this document, successive cleaning only one container is very time consuming and thus disadvantageous.

The known systems for cleaning systems consisting of individual components are basically designed so that during the cleaning and rinsing operation, all system components with their areas to be cleaned as well as the particular product-carrying connections and lines between the system components are arranged in series and thus a single , form by the respective cleaning and rinsing medium perfused 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.

If several different 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.

A facility that deals with a similar task has been created by the US 5,427,126 presented. In detail, this document is concerned with the cleaning of various, even temporarily connected to the cleaning device tanks and containers, these components are in no functional relationship to each other.

Since the components connected to the cleaning device of this document for cleaning do not form an overall system consisting of them together, each of these individual components can be cleaned when this component is connected to the cleaning device, or precisely when it is present for cleaning a component. A suggestion to improve the cleaning of existing systems consisting of several individual components can not be found in this document.

A disadvantage of known systems or in their cleaning and rinsing systems u.a., That for the cleaning and rinsing a relatively long time is needed. This is i.a. due to the fact that the total time required for the cleaning and rinsing operation depends on the longest treatment time required for a single system component, and in addition that all system components are treated in each case with all cleaning and rinsing media used in the cleaning and rinsing operation, although the Treatment of the system components with selected, each different cleaning and rinsing media would be more appropriate, especially with regard to the quality of the cleaning and rinsing results and in terms of the shortest possible total duration of the cleaning and rinsing process.

In practice, 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.

It is also a great disadvantage in known systems that only all system components located in series must be completely prepared for the subsequent cleaning process before it can begin. The preparation of the container filling machine is particularly complex, u.a. also because each filling station must be provided with a so-called rinsing cap or rinsing sleeve.

"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 are used. In this sense, system components include components for mixing various product components, for carbonating or for adding CO2 to products, for short-term heating or Pasteurization of products (also KZE units), buffer storage for products, filling machines, etc.

The object of the invention is to show a system which has a significantly improved cleaning and rinsing system for the system components. To solve this problem, a system according to claim 1 is formed. A method for cleaning system components of such a system is the subject of patent claim 16.

A special feature of the invention is that the cleaning and rinsing system for the cleaning and rinsing media each have an independent, formed by a ring line, closed system cycle in which also each of the cleaning and rinsing medium providing source is arranged.

The system components can be connected to this system cycle with a purge or purge path advance of their respective purge and purge path and with a purge or purge return of their respective purge and purge path via valve means, without interrupting the system cycle, i. such that the cleaning and rinsing path through the relevant system component is parallel to that part of the system cycle which extends between the cleaning or Spülwegvorlauf and the cleaning or Spülwegrücklauf and is still flowed through by the cleaning and rinsing medium. The cleaning and rinsing medium is thus tapped for cleaning and rinsing the system components in each case from the system cycle in the required amount and returned to this again. The ring circuits forming the system circuits are introduced to all system components for which cleaning and rinsing is required.

This makes it possible for several different cleaning media each separately provided system circuits or loops, during cleaning and purging different system components at the same time and / or temporally overlapping and / or offset with time treat the same or different cleaning and rinsing media and / or to choose the treatment duration of each system component for this component optimally and differently from the treatment time of other system components.

It is now also possible to treat the system components in an optimized sequence and with optimized procedures, so that the downtime of the entire system is significantly reduced. For example, it is particularly advantageous if the operating personnel first prepare the system component with the longest treatment duration-for example, the filling machine-and begin to clean this system component. As a result of this procedure, the work necessary for preparing the further system components is carried out parallel to the already running cleaning process of the longest-to-clean system component, which ultimately leads to a reduction of the standstill time.

In order to ensure that the cleaning and rinsing medium supplied to the respective system component is also returned to the system circulation leading to this cleaning and rinsing medium or to the corresponding ring line, that is, there is no or substantially no mixing of different cleaning and rinsing media each system component is designed with its own media separation.

With the cleaning and rinsing system a wide variety of cleaning and rinsing methods are possible, in particular also product-specific, ie specially adapted cleaning and rinsing methods for the respective product processed in the system. In addition to conventional cleaning and rinsing methods are also possible in which heated liquor and / or treated with a disinfectant and eg heated liquor and / or acid are used, dispensed with different products, especially in different drinks on a hot water sterilization when using hot lye or warm lye with disinfectant. This may be necessary To complete the cleaning and rinsing process with a treated, ie, for example, with a mixed with disinfectant water to achieve the required hygiene status of the system after cleaning and rinsing.
