Like any fresh produce, cut flowers are very fragile and perishable. They therefore require manipulation and specific treatments to ensure optimal presentation and preservation before and during the marketing. In general, the harvested flowers are stored in water buckets and conserved in cold rooms before order preparation for shipment in carton boxes.

In such a confined and humid atmosphere, the flowers may develop mold on the petal (Botrytis cinerea) that make them unsuitable for sale. The flowers may be contaminated with the fungus by air, water or through direct contact with other already contaminated flowers.

The petal mold, which grows even in refrigerated premises (positive cold), is responsible for significant losses in flowers, due to poor presentation but also of poor preservation. These airborne spores can easily, by cross-contamination, tackling all the flowers in storage areas and cause significant financial losses.

In addition to the necessary treatments of flowers by chemical products spraying or dipping at harvest, a common solution is to treat the air in warehouses using fungicide smokescreen. This way of disinfection is expensive, dangerous for the staff and leaves deposits on all surfaces, including the flowers.
It is also important to note that many studies highlight the ability of Botrytis strains to become resistant to the chemical substances usually used.


We offer an industrial concept of order preparation and treatment before packaging allowing the drying and disinfection of flowers before shipment, by directly treating problematic microorganisms at the source, that is to say on the surface of the flowers.



  • Minimum handling : the UVc Disinfection Tunnel is a compact and easy to move, so it can be easily integrated into an existing packaging line or process
  • Short disinfection time : high efficiency in minimum time.
  • Respectful and effective disinfection of flowers, but also healthier environment for the staff, the consumer by reducing the use and handling of disinfectants.
  • UVc Surface Disinfection system perfectly adaptable on an existing conveyor belt
  • Option to design a customized UVc disinfection system that can fit to different sized production processes.
  • Sterilization of all surfaces of the treated product
  • The combined treatment of cultures and its packaging can significantly reduce contamination by microorganisms resulting in a greater shelf life.
  • All UVRER surface disinfection systems are equipped with a lamp protection to ensure no broken glass is in contact with food in case of lamp breakage.
  • Significant reduction of use of chemicals for disinfection.
