METHOD AND DEVICE FOR FUMIGATING PRODUCTS IN AN ENCLOSED SPACE

摘要

Method for fumigating products (2) in an enclosed space (4), which consists in making the air in this space (4) circulate in a closed circuit through at least one flow- through module (13, 38-42) with adsorption means (15) in which treatment gas has been adsorbed; in activating means (16) which release the treatment gas from the adsorption means (15) until a sufficient quantity of treatment gas has been blown in the enclosed space (4); in switching off the means (16); and, as soon as the products (2) have been sufficiently fumigated, in recycling the treatment gas again by making the mixture of air/treatment gas circulate via the flow-through modules (13, 38-42) in order to have the treatment gas adsorbed in the adsorption means (15).
