Abstract

The present invention refers to a plant for carrying out a process for drying solid organic substances in aqueous phase. The plant includes a turbodrier and a continuous drier connected downstream of said turbodrier.

1 . A plant for carrying out a process for drying solid organic substances in aqueous phase, said plant comprising:
 a turbodrier, comprising a cylindrical tubular body with horizontal axis, equipped with at least one inlet opening for introducing said flow of solid organic substances in aqueous phase, at least one outlet opening for discharging the organic substances in disgregated wet solid form, a heating jacket for bring the inner wall of the tubular body to a predetermined temperature, a bladed rotor extending inside the cylindrical tubular body;   and a continuous drier connected downstream of said turbodrier.   
     
     
         2 . The plant according to  claim 1 , wherein said drier consists of a closet U-shaped cylinder or tube, comprising agitation/mixing means with rotary or alternating motion for mixing the flow of organic substances discharged by said turbodrier and fed into said drier. 
     
     
         3 . The plant according to  claim 2 , wherein said agitation/mixing means are selected from the group comprising Archimedean screws, agitators provided with pistons, partitions, blades, paddles, reels, cylinders, drum and ploughshares. 
     
     
         4 . The plant according to  claim 1 , wherein said drier consists of a rotary cylinder possibly equipped on the inside with mixing deflectors. 
     
     
         5 . The plant according to  claim 1 , further comprising at least one heat exchanger arranged between said turbodrier and said drier, said heat exchanger being dedicated to the recovery of the latent heat of the steam generated in said turbodrier to provide heat energy to said drier. 
     
     
         6 . The plant according to  claim 2 , further comprising at least one heat exchanger arranged between said turbodrier and said drier, said heat exchanger being dedicated to the recovery of the latent heat of the steam generated in said turbodrier to provide heat energy to said drier. 
     
     
         7 . The plant according to  claim 5 , wherein said recovered heat is used to heat up a heating jacket foreseen in said drier. 
     
     
         8 . The plant according to  claim 6 , wherein said recovered heat is used to heat up a heating jacket foreseen in said drier. 
     
     
         9 . The plant according to  claim 5 , wherein said recovered heat is used up to heat up a flow of gas fed to said drier. 
     
     
         10 . The plant according to  claim 6 , wherein said recovered heat is used up to heat up a flow of gas fed to said drier. 
     
     
         11 . The plant according to  claim 9 , wherein said flow of gas is fed in countercurrent to said drier. 
     
     
         12 . The plant according to  claim 10 , wherein said flow of gas is fed in countercurrent to said drier. 
     
     
         13 . The plant according to  claim 1 , comprising a pair of heat exchangers arranged in parallel to one another and arranged between said turbodrier and said drier, said heat exchangers being dedicated to the recovery of said heat to respectively heat up said heating jacket foreseen in said drier and said flow of gas fed into said drier. 
     
     
         14 . The plant according to  claim 2  comprising a pair of heat exchangers arranged in parallel to one another and arranged between said turbodrier and said drier, said heat exchangers being dedicated to the recovery of said heat to respectively heat up said heating jacket foreseen in said drier and said flow of gas fed into said drier.
