Abstract:
The invention relates to a process for treating fruit and vegetables after harvesting, using, as plant-protection treatment composition, the mixture with water of the reaction medium resulting from the implementation of steps of purification of a plant-protection product contaminated with impurities of aromatic primary amine type. The process contains the steps of: a) the placing in contact with stirring, at a temperature between 15 and 25° C., of an aqueous solution of an alkali metal nitrite with an organic solution prepared by dissolving the said plant-protection product to be purified in a solvent chosen from a nonionic surfactant, a C2-C12 glycol and mixtures thereof; b) the addition of a strong inorganic acid to the resulting reaction medium, while stirring at the said temperature; c) followed by heating of the reaction medium to a temperature of between 30 and 70° C.
Abstract:
The present invention relates to a method for fungicidal and/or bactericidal treatment of plants or foodstuffs using one or more essential oil(s) that enable the treatment of strains resistant to synthetic fungicides and/or bactericides.
Abstract:
A device for coating food products, of the type having a coating area includes: a coating conveyor provided to drive said food products in a longitudinal direction; and a device for applying a coating compound on the food products driven on the conveyor. The coating conveyor includes a chassis, a plurality of rotary brushes fastened in the longitudinal direction relative to the chassis, and a motorized assembly for driving the brushes in rotation around respective transverse axes relative to the chassis, the brushes being arranged so as to define, together, a support and driving surface for the food products and being provided to make the food products roll during the application of the coating compound.
Abstract:
The present invention relates to solutions of CIPC and of one or more terpenes or terpene oils for the antigerminative treatment of bulbs and tubers. This use is particularly appropriate for the treatment of potato tubers. The CIPC solution contains from 50 to 80% by weight of CIPC relative to the total volume of the solution. Examples of the terpenes and terpene oils are eugenol, isoeugenol, clove oil and their salts and mixtures thereof.
Abstract:
A process for treating, by means of eugenol or clove oil, reservoirs for storing cereals, oil-producing plants, dry fruit or dry vegetables contaminated with mycotoxins.
Abstract:
The present invention relates to a composition comprising one or more active ingredients of plant origin, or their synthetic analogues or extract(s) of plant origin containing them, encapsulated by the lecithin in an aqueous solution.
Abstract:
A process for the anti-germination and/or biocide treatment of bulbs or tubers by separate application of 3-chlorophenylisopropylcarbamate (CIPC) and a component selected from the group consisting of clove oil and eugenol, in this order or vice versa. The process may be used for the treatment of potato tubers.
Abstract:
The device for generating electricity (1) comprises:a first heat pump (3) provided with a first closed circuit (15) in which a first heat-transfer fluid circulates, and with a first heat exchanger (17) between the first heat-transfer fluid and a flow of atmospheric air in which the flow of atmospheric air transfers a quantity of heat to the first heat-transfer fluid,at least a second heat pump (5), provided with a second closed circuit (23) in which a second heat-transfer fluid circulates, and with a second heat exchanger (25) between the second heat-transfer fluid and a third heat-transfer fluid in which the second heat-transfer fluid transfers a quantity of heat to the third heat-transfer fluid;means for transferring a quantity of heat from the first heat-transfer fluid to the second heat-transfer fluid;a third closed circuit (9), in which the third heat-transfer fluid circulates;a turbine (11) inserted on the third closed circuit (9) and driven by the third heat-transfer fluid; an electric generator (13), mechanically driven by the turbine (11).
