\"VacuumVacuum Cooling for Cut Flowers | Vacuum Coolers for Flower Growers<\/h1>

For commercial flower growers, packhouses and exporters, maintaining quality after harvest starts with rapid temperature reduction<\/strong>.<\/p>

Freshly cut flowers remain biologically active after harvesting. Respiration continues, moisture can be lost and deterioration begins. The longer freshly harvested flowers remain warm, the greater the challenge of maintaining their quality throughout storage, transportation and distribution.<\/p>

This is why vacuum cooling for cut flowers<\/strong> can provide an effective post-harvest cooling solution for commercial flower growers.<\/p>

Cold Change Group is a specialist vacuum cooler manufacturer<\/a> supplying industrial vacuum cooling systems to growers, packhouses, exporters and fresh-produce businesses internationally.<\/p>

Our vacuum cooling equipment<\/a> ranges from compact single pallet vacuum coolers<\/strong> through to large 20 pallet industrial vacuum cooling systems<\/strong>, allowing equipment to be selected around the actual production requirements of each operation.<\/p>

What Is Vacuum Cooling for Cut Flowers?<\/h2>

Vacuum cooling is a rapid pre-cooling process that removes heat through controlled evaporation under reduced atmospheric pressure.<\/p>

Freshly harvested flowers are loaded into a sealed vacuum chamber. Powerful vacuum pumps then progressively reduce the pressure inside the chamber.<\/p>

As pressure falls, the boiling point of water also falls.<\/p>

This allows a small quantity of moisture to evaporate at a low temperature. The energy required for evaporation is taken from the product itself, rapidly removing heat.<\/p>

This is fundamentally different from conventional cold-room cooling.<\/p>

Rather than relying entirely on cold air gradually transferring heat away from the outside of the product, a vacuum cooler for cut flowers<\/strong> can rapidly remove heat throughout suitable loads as chamber pressure is reduced.<\/p>

You can learn more about the technology and available machine configurations through the complete Cold Change vacuum cooling range<\/a>.<\/p>

Why Do Cut Flowers Need Rapid Pre-Cooling?<\/h2>

Temperature management is one of the most important parts of the post-harvest flower cold chain.<\/p>

Flowers harvested from a greenhouse or field can retain significant field heat.<\/p>

Simply placing warm flowers inside refrigerated storage does not mean that the flowers themselves immediately reach the required temperature.<\/p>

Heat still needs to transfer from the product into the surrounding refrigerated air.<\/p>

Packaging, bunch density, airflow, pallet configuration and starting temperature can all influence this process.<\/p>

The objective of rapid pre-cooling of cut flowers<\/strong> is therefore to remove field heat as quickly as practical and establish the cold chain soon after harvest.<\/p>
