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%.

Abstract: A method for the concentration of liquid mixtures includes the step of causing a continuous stream of the liquid mixtures to flow in the form of a turbulent thin layer in contact with a heated wall; for that purpose, a continuous stream of liquid mixture is fed into a turbo-concentrator including a cylindrical tubular body (1), a heating jacket (4) and a bladed rotor (8) rotatably supported in the cylindrical tubular body (1), and is centrifuged to form a dynamic and tubular thin layer, the thin layer advancing inside the cylindrical tubular body (1) then being discharged continuously in the form of a stream of concentrated liquid mixture.

Abstract: A method for the continuous crystallization of sugars or polyols, comprising the steps of: arranging in a thin, turbulent and dynamic layer a continuous flow of melted mass of a compound selected among the group comprising sugars and polyols, with at least 98% of dry material, and a mass of said compound in crystalline form as a crystallization seed; advancing said thin layer of material along a cooling wall at a temperature between −15° C. and +5° C.; granulating the material while said thin layer is advanced along the cooling wall, thus obtaining granules of the crystallized compound, and cooling said granules to room temperature, after a predetermined maturation time.

Abstract: In order to produce a frozen, composite food product including at least two components, a continuous flow of pieces of the first component is advanced along a mixing tank in which the pieces are simultaneously tossed and a continuous flow of at least one second component is spread on the first component as it advances through the mixing tank.

Abstract: A process for treating so-called wet refuse of urban origin, especially food waste from canteens, communities and other similar catering establishments, and originating from the food industry and the agrifoods industry, including the phases of subjecting a continuous stream of said wet refuse, previously ground, to heating to a pasteurization/sterilization temperature for the time needed for complete cooking, to give a continuous pasty and wet stream of cooked and sanitized refuse and subjecting the said continuous stream to drying, to give a product having a moisture content of not more than 15%.

Abstract: A process for producing cellulose from vegetable raw materials containing same by reacting these with digesting agents is described, comprising a preliminary size reduction of said raw materials to give a pumpable material, and a heat treatment of said material, arranged in a thin layer and maintained in a state of high turbulence, with at least one digesting agent; the abovementioned treatment is preferably carried out in a turboreactor and produces a mixture of cellulose fibres and of spent digesting agent, from which cellulose fibres ready for the uses in the paper industry are obtained via subsequent washing and separation phases; the process described is particularly suitable for the production of cellulose from annual plants in high yields, in very short times and at costs substantially reduced as compared with known processes.

Abstract: Apparatus for the purification of gas and vapor streams by the removal of solid, liquid or aeriform polluting substances; the apparatus including a stator formed as a tubular body having a cylindrical inner wall, which body is furnished with at least one inlet aperture for the admission of gas or vapor streams containing solid, liquid or gaseous impurities and with at least one discharge aperture, a coaxial rotor extending longitudinally and revolvably supported inside the tubular body in such a way as to define with the cylindrical wall at least one annular passage, and an inlet for the admission of liquid into the tubular body.

Abstract: A process is described in which hospital refuse is comminuted to a powder-like consistency or at least so as to be capable of being pumped and subsequently subjected to heat sterilisation treatment in a highly turbulent dynamic thin layer.

Abstract: A conching step for the production of chocolate is described and is carried out by means of a turbomixer which arranges the previously refined chocolate paste in a thin, dynamic layer which flows in contact and in a heat-exchange relationship with an internal wall of the turbomixer.

Abstract: A method for making a granular product including sodium silicate and its water of crystallization, having a specific weight of from 0.5 to 1.2 and completely soluble in water at ambient temperature includes the step of granulating a pseudoplastic mass of sodium silicate having a free water content of between 5 and 12% by weight under hot conditions in an air-steam environment.

Abstract: A method for eliminating pollutants and/or bad-smelling substances from a gaseous flow produced by the drying of a damp substrate provides for the separation of suspended solids, dehumidification, the heating and recycling of the gaseous flow to a drying apparatus after extraction of a portion of the flow and subjection of this portion to combustion with the simultaneous destruction of the pollutants and/or bad-smelling substances.

Abstract: In order to produce a frozen, composite food product including at least two components, a continuous flow of pieces of the first component is advanced along a mixing tank in which the pieces are simultaneously tossed and a continuous flow of at least one second component is spread on the first component as it advances through the mixing tank.
