4 CA chambers for insect treatment of tobacco

Investor: Socotab EOOD
Location: Radinovo, Plovdiv
Commissioning: November 2016

Project information

By reducing the oxygen level in a gas-tight room to less than 0.5%, the system is able to achieve a 100% mortality rate for all insects in all development stages: eggs, larvae, pupae and adults.

Controlled Atmosphere / Low Oxygen Treatment is completely safe and natural: since no chemicals are applied, no (toxic) residues remain on the stored product and insects are unable to build up resistance. This natural treatment method meets the strictest regulations for fumigation, including those that apply for organic food supply (EEC 2092/91 and NOP).

The volume of the individual chambers exceeds 700 C48 cartons (>7 pcs. 40 Ft containers).

The Controlled Atmosphere (CA) Chambers have been designed to optimize the logistical flow.

They are the first CA chambers for treatment of tobacco realized in Bulgaria.
