In a packaging line, the quality of the finished product does not depend solely on dosing accuracy, consistent capping or label application. It can start earlier, with the preparation of the container itself. Whether bottles, vials or jars, containers can accumulate dust, micro-debris or residues during manufacturing, storage or transport.
Integrating a container air rinsing machine helps secure the upstream stage of the filling process by improving packaging hygiene. In certain sectors, such as food processing and pharmaceuticals, this operation can even become a genuine performance driver.
But how can a container air rinsing machine be integrated into an existing line or a new packaging project? Where should it be positioned? Which machines should it be combined with?
Why integrate a container air rinsing machine into a packaging line?
A container air rinsing machine is designed to clean the inside of containers. The principle is simple: the container is handled, inverted and then positioned in front of a nozzle through which a flow of compressed air expels dust and particles. This operation takes place upstream of filling and, when the integration has been properly designed, does not slow down the line. The benefits of such a machine are numerous:
- Preserve the quality of the finished product;
- Improve hygiene throughout the packaging line;
- Reduce the risk of returns, non-conformities or customer complaints;
- Improve line reliability by adding an upstream cleaning and preparation stage.
At CDA, this approach is part of a global vision of packaging: every machine must contribute to the overall performance of the process, from the arrival of the container to the finished product. The Win-Dy container air rinsing machine has been specifically designed to integrate upstream of other CDA equipment, including filling machines, capping machines, closing machines, labelling machines and monobloc systems. The Win-Dy automatically inverts the containers and performs internal air rinsing before filling.
Where should the air rinsing machine be positioned in the line?
In most cases, the air rinsing machine is positioned between the container infeed and the filling machine. The process generally follows this sequence:
- Infeed table or line entry system
Bottles, vials or jars are fed regularly onto the conveyor. - Container air rinsing machine
The machine takes the containers, inverts them if required and removes particles from inside. - Automatic or semi-automatic filling machine
Once the containers are clean, they are transferred to the dosing/filling machine suited to the viscosity of the product. - Capping or closing machine
Caps, closures, pumps or pipettes are positioned and tightened according to the selected technology. - Labelling machine
The closed product is then labelled with one or more labels, according to the specifications.
This position helps minimise the time between cleaning and introducing the product into the container. It is particularly relevant when packaging is stored on-site, handled at several workstations or exposed to a dusty environment.
Which criteria should be considered before integrating an air rinsing machine?
Integrating a container air rinsing machine is not simply a matter of “adding another machine” to a conveyor. To ensure that it delivers genuine value to the packaging line, several parameters need to be considered.
The type of container to be processed
The first criterion is, naturally, the container itself:
- rigidity (glass or plastic);
- neck diameter;
- height, weight and stability;
- specific geometry.
These characteristics will influence the gripping, inversion and air-rinsing systems. A line processing small 10 ml vials will have different requirements from a line designed for wider jars or taller bottles.
The CDA Win-Dy has been designed to accommodate different container formats and several materials, making it an interesting solution for multi-format lines.
Production rate
The air rinsing machine must be consistent with the overall line speed. Installing an air-rinsing system that becomes a bottleneck for the entire line would be counterproductive. It is therefore important to consider the line speed as a whole:
- How many containers per hour need to be processed?
- Is the production rate stable or does it vary according to the format?
- Does one container need to be rinsed at a time, or several simultaneously?
- Does the line need to accommodate production peaks?
The Win-Dy can reach speeds of up to 1,200 containers per hour (on certain jar formats, and even higher speeds with lighter containers), allowing it to be integrated into a wide range of configurations.
The nature of the product being packaged
The more sensitive the product, the more critical container cleanliness becomes. This is particularly true in the food processing industry. Integrating an air rinsing machine upstream of the filling machine is not simply a matter of operational convenience: it is a way of securing the process.
The configuration of the existing line
For an existing line, the following elements need to be checked:
- available space;
- working height;
- direction of container flow;
- mechanical and electrical interfaces;
- accessibility for cleaning and maintenance;
- synchronisation with the other machines.
Successful integration requires an overall approach: the air rinsing machine must be compatible with the conveying system, the speeds of the filling, capping and labelling machines, as well as transfer times between stations.
The filling machine: the heart of the dosing process
After air rinsing, the clean container is transferred to the filling machine. This machine must be selected according to:
- product viscosity;
- required dosing accuracy;
- filling volume;
- target production rate;
- desired level of automation.
In a well-designed line, the air rinsing machine feeds the filling machine at a consistent rate, without sudden interruptions or excessive accumulation. The conveyor, stops, sensors, transfers and other components must therefore be designed to work together.
At CDA, our filling solutions meet a wide range of requirements, both automatic and semi-automatic, for liquid, fluid, viscous or more complex products to dose. For example, the K-Line S can be integrated downstream of the Win-Dy.
The capping / closing machine: ensuring reliable container closure
Once the product has been dosed, the container must be closed with the required production rate and repeatability. Depending on the application, this may involve:
- a screw cap;
- a closure;
- a pump;
- a dropper cap;
- a tamper-evident or safety system.
Here again, consistency between the different stations is essential. For example, following a Win-Dy and a K-Line S, the line can incorporate a VS 2000.
The labelling machine: the final product enhancement stage
After cleaning, filling and closing, labelling completes the product. This stage is not purely aesthetic: labels also carry essential information relating to traceability, use, compliance and branding.
A properly sized line must prevent the labelling machine from becoming overloaded by the upstream stations. CDA offers a range of labelling machines that can be integrated into complete lines, with configurations suitable for cylindrical, flat and conical containers, such as the Ninon Mix.
The practical benefits of a container air rinsing machine
When properly integrated, a container air rinsing machine does much more than simply “blow air” into a package. It contributes to the overall efficiency of the packaging line.
- Better quality control
The first benefit is clear: the container reaches the filling machine clean. This helps reduce the risk of foreign bodies entering the product and improves consistency in terms of quality.
- Improved hygiene throughout the line
In sectors where hygiene is a major commercial or regulatory consideration, air rinsing containers is a logical stage in the process.
- Fewer incidents
A cleanliness issue detected after filling or labelling will always be more costly to address. By positioning the air rinsing machine upstream, the issue is addressed at the right stage: before the added value provided by the product, closure and labelling.
- Integration into a complete line
The Win-Dy has been designed as a complementary solution to CDA packaging equipment. It can therefore form part of a complete line approach incorporating filling, capping and labelling.
A container air rinsing machine: an investment in performance
Long considered a complementary piece of equipment, the container air rinsing machine nevertheless has an important role to play in packaging projects. The reason is simple:
Integrating an air rinsing machine upstream of filling helps make container preparation more reliable and strengthens the consistency of the entire line. It naturally works alongside a filling machine, capping machine and labelling machine.
At CDA, this continuity between air rinsing, filling, capping and labelling stations is part of a global approach to packaging. The Win-Dy therefore complements an ecosystem of machines designed to meet a wide range of requirements.
