Drying of Packaging

  • Up to 45% subsidized acquisition costs

  • Save up to 75% on energy costs

  • 100% planning reliability thanks to premium after-sales service

Primary and secondary packaging made of plastic, glass, or metal, metal strips, plastic films, or thin liquid films on surfaces must be reliably dried after cleaning, pasteurization, or sterilization to allow for subsequent printing, labeling, final packaging, or further processing.
With the Airgenex® condensation drying developed by HARTER, packaging can be dried efficiently and in no time, whether in a continuous process or in batch operation.

Bottles

Glass or plastic bottles, ampoules, or vials – if their exteriors are not completely dry, leak testing or optical inspection will sort them out as supposed rejects. To remedy this shortcoming, the use of powerful drying is advisable. Our Airgenex® drying system increases your productivity, improves your product quality, and simultaneously ensures maximum process reliability.

Blisters

For blister packaging that requires drying after sterilization, for example, Airgenex® condensation drying with its low temperatures is recommended for stress-free drying of both the packaging and the product. Seemingly contradictory attributes such as short drying times and product protection are easily achieved here.

Pouches

Primary packaging such as infusion bags for the pharmaceutical industry or sauce pouches for the food sector are moist after autoclaving and require thorough drying. Very often, cooling is also necessary for subsequent processes. Due to its physical approach, heat pump condensation drying can easily be used for both in combination with minor adjustments – whether as a batch dryer or a continuous dryer.

Film Packaging

If film packaging or its contents are to be pasteurized for their intended purpose, for example, subsequent drying is necessary, and possibly also cooling. Our heat pump-based condensation drying can do both. And, above all, it can safely, completely, and gently dry packaging that is present as bulk material.

Convenience Food

Are you also among the aspiring manufacturers of Convenience Food who want to secure a leading position in this rapidly growing market? Then a good and reliable drying solution should be an integral part of your concept and planning from the outset. We are familiar with drying problems related to opening aids, excessive moisture after pasteurization, temperatures too high for further processing, and so on – all of this can be solved by using Airgenex® condensation drying.

Canned Goods and Beverage Cans

Many blowers and dryers can no longer keep up with the high speed of a production line. Cans with excessive external moisture or water droplets on the tabs halt the entire operation. An unacceptable situation in high-throughput companies. Extremely dry air, precise air guidance, and a compressed air-free blow-off technology – this combination guarantees fast and complete drying of the products, so that they can be immediately printed and further processed.

Stand-up Pouches

The complete drying of this form of packaged food or feed is inherently a major challenge – and therefore exactly what we are good at! With our perfect combination of extremely dry air, targeted air guidance, and, if necessary, compressed air-free blow-off technology, we can implement solutions for you that will dry your products quickly and safely.

Your benefits

A combination of efficient dehumidification and targeted air guidance ensures extremely short drying times. The right air in the right place – for you, this means: drying in seconds.
Your products are dried within a variable temperature range of 20°C to 90°C. Drying at low temperatures protects the packaging and its contents.
The integrated heat pump technology and the closed air circuit ensure maximum efficiency in the drying process. Drying is independent of external climatic factors. The processes are safe and reproducible.
If desired or required by the process, our Airgenex® system can also be used for cooling with minor adjustments. Heat pump-based condensation drying is a process that, due to its physical approach, can easily be used for both.
In particularly demanding cases, we offer compressed air-free blow-off technology. For this, we use specially developed blow-off nozzles. The blow-off can be implemented as a preliminary stage to the actual drying process or as a separate blow-off station.

Drying Systems for Packaging

We develop and manufacture drying systems for both batch operation and continuous processes, thereby adapting our technology to your process and your product. We determine all specific parameters for successful drying beforehand in drying tests at our technical center.

Our success is based on the perfect combination of two components – efficient dehumidification and precise air guidance. At low temperatures, we guide extremely dry and thus unsaturated air precisely to where it is intended to absorb moisture.

We implement this process – our heat pump-based condensation drying – in a wide variety of system types.

The Process

We dry with dry air and deliver it to the right places: A perfect interplay of air preparation and air guidance provides you with the best possible drying result.

Interface: Airgenex® Dehumidification Technology / Dryer – Moist air is extracted from the drying chamber and supplied to the dehumidification unit.

The pre-cooler pre-cools the air in a first stage. This significantly reduces the compressor’s energy consumption.

Moisture condenses on the fins of the air cooler and drains out of the drying system via the drip tray and condensate drain.

The cooled, dehumidified air is warmed up without additional energy by means of a pre-heater.
The air heater warms the air to the required process temperature.

The process air fan ensures the necessary air exchange between the Airgenex® dehumidification technology and the drying chamber.

Now, the dry, unsaturated air is guided into the drying chamber, where it absorbs the product’s moisture. Thus, the cycle is closed.

Efficiency that pays off.

Our HARTER drying systems save up to 75% CO₂ and are up to 45% governmentally funded.

What Our Customers Say

Not convinced yet? Our customers are thrilled!

“Sometimes it’s better to say nothing and let your customers speak for themselves.”
– Regina Mader, Managing Director

“For several decades, we have been using a Harter sludge dryer in our contract electroplating facility and are very satisfied with it. The technology and service are reliable and have helped us save a significant amount of money on disposal.”

Daniel Hutter
Verzinkerei Kriessern AG

“BK Giulini GmbH has been successfully collaborating with Harter GmbH for approximately 20 years. We are very satisfied with both the dryer technology and the reliability of the entire system. Based on these positive experiences and the excellent service, we invested in another drying system of this type in 2023.”

Dimitri Baumbach
ICL Ladenburg / BK Giulini GmbH (ICL Group)

“In our waste incineration plant, we have saved a significant amount of money by drying our heavy metal-containing hydroxide sludge. The plant technology is sustainable and maintenance-friendly. In retrospect, the investment was a very good decision.”
