Vacuum cooling for Flowers & Cold Chain Management

Vacuum cooling of roses in Kenya

Uhuru, which means "freedom" in Kiswahili, is located on the northern slopes of Mt Kenya near the city of Timau. The farm is located at an altitude of 2600 meters above sea level, making it one of the highest rose farms in Kenya.

The altitude combined with the latitude (they are located just a few kilometers from the equator) ensure that Uhuru can produce top quality roses all year round. Their goal is to produce consistent, high-quality cut roses with a large head size, excellent vase life and ultimate presentation.

Weber Cooling assisted Uhuru with the installation of a Weber Compact vacuum cooler, which guarantees the high quality of the flowers that Uhuru strives for.

No more quality claims in Ecuador

The Ecuadorian freight forwarder EBF Cargo has just acquired a new vacuum cooling machine which is fully operating now. “The process is ultra-fast, in only 20 minutes the process is completed and the flowers ready to go”, says Commercial Manager Patricio Brito.

A vacuum cooling machine cools down the flowers and takes out the undesired humidity of the flowers in a stable way by creating vacuum inside the chamber. Over the last years this technique has been used more often and transporters are becoming more aware of the benefits. Patricio: “Flowers leave with the right temperature and can better endure temperature changes during transportation, thus improving cold chain management. Also the quality of the flowers is preserved and the vase life increases. Plus the risk of botrytis and insects is reduced.”

The machine is located inside their cooler rooms. Vacuum cooling can be used on all types of flowers which need cold chain management i.e roses, carnations, gypsophila, pincushions and more.

Clients of EBF Cargo have started using this process and Patricio says the feedback is great. “Our clients have no quality claims anymore from their own clients. This process is especially useful for clients who send their product to destinations with long transit times and/or a lot of connections in between. It also applies to clients using sea transportation for flowers.”

Airports worldwide

“Vacuum is the only efficient and effective cooling option at the airport, to cool down combined shipments to temperature where the products are in hibernation state”, claims Hans Juursema of Weber Cooling.

“Only this way substantial heating up during transportation can be prevented. And even a few degrees higher temperature on departure can result in un-acceptable high temperatures at the arrival side.”

Weber Cooling is the new leader in airport cooling solutions, with on average 3 (!) new vacuum rooms installed each year, at airports in Europe, Eastern Africa & South-East Asia and the USA.

Prevention of Botrytis in the UK

One of the leading importers in the United Kingdom for fresh flowers (mainly roses) from Columbia has tested our Weber vacuum coolers extensively, and made a full report, of which we are allowed to share the conclusions with you:

Vacuum Cooling reduces moisture in packed flowers. Therefore there is hardly any Botrytis thanks to dryer conditions in the sleeve.

“Vacuum cooling is a quick, effective approach to reducing temperature
… removing condensation from sleeves has positive effects on botrytis reduction
… time (along with pressure) is a critical factor in the cooling process
… vacuum cooling at the arrival site does not have any detrimental effect on vase performance, but is positive for the reduction of rejects & complaints”.

Hypericum in Kenya

Hypericum is cooled in vacuum by a leading grower of roses and hypericum in Kenia for 15 years already.

Wildfire Flowers (Kenya) own a vacuum cooler for about 15 (!) years, and use it almost daily to cool down their Hypericum with little to no maintenance worries.

Perfect cooled Hypericum brings top quality & minimal rejects

Ann Mugi, sales manager: “With vacuum we can cool down our Hypericum within around 15 – 20 minutes, from around 20 °C down to 2 °C. Only this way we can guarantee top quality of our delicate flowers after shipment to Europe!”

Tulips in The Netherlands

Since spring 2015 at Ruiter Wever the latest generation "Weber Cooling" vacuum coolers is running to cool tulips.

The choice for vacuum cooling was made on the basis of the advantages of this technique for speed and uniformity of cooling back.

Weber Cooling was chosen for the unique price-performance ratio.
