Abstract:
The treatment unit includes an evaporation device including a gas circulation pipe, and a material with a large specific surface filling an evaporation section of the circulation pipe; a device for circulating the gas through the circulation pipe; a liquid impregnating the material with a large specific surface, the liquid containing at least one product or a mixture of volatile biocide and/or phytoprotective products, with a boiling temperature between 130 and 280° C., the material with a large specific surface having a liquid retention capacity greater than 50 L/m3 of material with a large specific surface at 20° C.; a recharging device, arranged to re-impregnate the material with a large specific surface with liquid or to replace the spent material with a large specific surface with a new material with a large specific surface impregnated with liquid.
Abstract:
A method of treating the atmosphere of a storage of vegetable products with a volume greater than 200 m3, wherein the method comprises at least one step of contacting the atmosphere with a liquid flow by circulation in a packing. A treatment unit of the atmosphere of a storage of vegetable products having a volume greater than 200 m3, wherein the unit comprises a contacting device comprising a packing, a device for injecting a liquid flow into the contacting device, a device for circulating the storage atmosphere in the contacting device, wherein the contacting device is so designed that the atmosphere is brought into contact with the liquid flow by circulation in the packing.
Abstract:
The process includes a treatment step during which a liquid containing a biocidal and/or plant-protection product or a mixture of biocidal and/or plant-protection products is evaporated and injected into the internal atmosphere of premises, the liquid being evaporates at a temperature of less than 50° C., the product vapour concentration in the internal atmosphere of the premises being kept at greater than 10% of a saturation concentration of the vapour of said product in said atmosphere at said temperature for a saturation duration of greater than 12 hours.
Abstract:
A method of treatment with at least one biocidal and/or safener product with a boiling temperature between 60 and 280° C., wherein the method comprises a treatment step duration greater than or equal to 3 days, wherein the treatment step comprises at least one injection phase of a duration greater than or equal to 3 days during which a liquid containing the, or each, product is evaporated and injected inside an enclosure, wherein the liquid is evaporated and injected with a period of less than or equal to two days during the injection phase, wherein the liquid is evaporated at a temperature below 50° C.
Abstract:
The protection process comprises transporting vegetable products (1) in an enclosure (3), a phyto-protective treatment being applied simultaneously by placing a quantity of a porous mineral or vegetable material (5) inside said enclosure (3), in which a liquid containing an essential oil or a constituent of an essential oil is absorbed;
the porous mineral or vegetable material (5) having a liquid absorption capacity of between 5% and 30% by weight at 20° C.; the evaporation rate of the liquid absorbed in the porous mineral or vegetable material (5) being between 10 and 200 g per day and per kg of absorbed liquid at a temperature suitable for the preservation of the vegetable products and at atmospheric pressure; the porous mineral or vegetable material (5) being arranged inside at least one openwork container (7) allowing an internal atmosphere of the enclosure (3) to circulate through the openwork container (7) in contact with the porous mineral or vegetable material (5).
Abstract:
An apparatus for treating the atmosphere of a storage space for vegetable products with a volume greater than 200 m3, includes a contacting device having a packing; an injector configured to inject a liquid flow into the contacting device; and a circulator configured to circulate the storage atmosphere in the contacting device. The contacting device is configured such that the storage atmosphere is brought into contact with the liquid flow by circulation in the packing.
