Processes and methods for producing dried fruit which has been treated with sulphur dioxide. Such processes and methods are particularly adapted for producing golden raisins which have relatively low concentrations of sulphur dioxide. To produce golden raisins, fresh sultana grapes are subjected to sulphur dioxide fumigation before undergoing a series of washing and rinsing steps which may include a cold water bath, a hot lye bath, and cold water sprays before being placed into drying tunnels. After drying, golden raisins may be undergo an additional treatment of sulphur dioxide.

A device and related degassing method for granular or powder material and the use of a blower element, wherein a containment chamber of the granular or powder material and of a gas produced by said material is provided, means for supplying an injection gas with the gas produced by the material comprising the blower element for feeding the injection gas into said chamber for mixing and/or homogenizing the material and the relative gas produced by the material itself with the injection gas.

A method for treating a perishable product including determining a desired product treatment outcome selected from sanitation, protection, preservation, or enhancement of the perishable product; directly applying a substance to the surface of the perishable product after harvesting using a carrier; wet or dry washing the perishable product; and packaging the perishable product. A system for treating a perishable product with a substance treatment including one or more devices for directed substance application to a surface of the perishable products prior to final packaging of the perishable product using a carrier; and wherein the one or more devices is an electrostatically charging device or a nebulizer. Embodiments of the invention enhance the efficacy of sanitizers and other functional substances for increasing the quality, safety, and overall shelf life of perishable products through improved coating and distribution of the sanitizers and functional substances on the surface of perishable product.

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/m.sup.3 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.
