Abstract: A process for the oxidation of powder materials containing starch, which comprises the steps of mixing a powder material comprising starch with an aqueous solution of hydrogen peroxide (H2O2), adding to the mixture thus obtained an aqueous solution of ammonia which reacts with said mixture and drying the mixture to obtain a powder material containing oxidized starch.

Abstract: Process for the production legume meal having a moisture content between 2% and 15%. The process includes feeding a continuous flow of legume meal into a wet heat treatment reactor together with a continuous flow of water or aqueous solution, which is dispersed into minute droplets; discharge the wet legume meal and feeding it into a thermal dehydration and treatment reactor.

Abstract: A product in powder form having a dry matter content of at least 90% by weight on its total weight and containing lactose in a quantity of at least 85% by weight on its total weight, as well as having a high bulk density; moreover a process for the production of this product in powder form is disclosed, comprising the steps of vacuum-concentrating a lactose-containing liquid, mixing the so-concentrated liquid with a lactose-containing powder and with a high dry matter content and, finally, drying the so-obtained powdered mixture.

Abstract: Process for recovering phosphorus from ashes coming from combustion plants that are fed with renewables and/or waste materials as solid fuel, comprising a phase of mixing said ashes coming from combustion plants that are fed with renewables and/or waste materials as solid fuel with a sulfuric acid solution, in order to extract the phosphorus therein contained; a system for carrying out said process is also described.

Abstract: An optimized process and system for the production of a heat exchange fluid heated by means of combustion of a fuel are described, said process comprising the steps of: —burning a fuel in a combustion chamber, thus generating a flow of exhaust gas, said flow comprising solid particulate matter and/or combusted or uncombusted particles; —introducing said flow of exhaust gas into a unit suitable for the forced abatement of the solid particulate matter and/or combusted and uncombusted particles, thus obtaining a purified exhaust gas flow and a solid precipitate which comprises solid particulate matter; —transferring the flow of purified gas to a generator of a heated heat exchange fluid, inside which a heat exchange fluid flows; —carrying out an indirect heat exchange, thus obtaining a flow of cooled purified exhaust gas and a heated heat exchange fluid.

Abstract: A process is described for drying melamine wet cakes, comprising the steps of: a) providing a turbo-dryer (T) comprising a cylindrical tubular body (1) having a heating jacket (4), inlets and outlets (5, 6) and a bladed rotor (7) rotatably supported therein; b) feeding a continuous flow of a melamine wet cake into the turbo-dryer (T), the internal wall (9) of which is maintained at a temperature of at least 220° C.; c) feeding a continuous flow of a gas selected from air or nitrogen into the turbo-dryer (T); d) subjecting the flow of melamine wet cake to the mechanical action of the bladed rotor (7) rotating at a speed of at least 200 rpm, with consequent centrifugation of the wet cake against the heated wall (9), thus causing the instantaneous evaporation of the water contained into the cake, and transport of the latter towards the outlet (6); e) continuously discharging, after an average residence time of less than 1 minute, a flow of melamine crystals having a humidity content of less than 0.1%.
