first embodiment
[0033]FIG. 1 shows a carbonizing system for carbonizing residues produced in a coffee extraction process, i.e. coffee grounds. This carbonizing system includes, mainly, a receiving hopper 3 into which coffee grounds are introduced as material under treatment 1, a drier 4 for drying the material under treatment 1, a dried material storage tank 5 for storing the dried material under treatment 1 (1a), a carbonizing apparatus A according to this invention for carrying out carbonizing treatment of the dry material under treatment 1a, and a carbide storage tank 7 for storing carbide 2 obtained. This carbonizing system further includes a screw feeder 8 for transporting the material under treatment 1 in the receiving hopper 3 to the drier 4, a dry material transporting device 10 for transporting the dry material under treatment 1a dried in the drier 4 to the dry material storage tank 5 or a hopper 9 for delivery to the outside, a dry material feeding device 11 for feeding the dry material u...
second embodiment
[0055]FIG. 5 shows a different embodiment of a carbonizing system according to this invention. In this carbonizing system, a cylindrical drier 104 is disposed on top of and coaxially and integrally with a carbonizing apparatus A. As a drying gas supply path 166 for supplying the drier 104 with exhaust gas generating in a combustion furnace 180 of the carbonizing apparatus A as drying gas, a duct 165 connecting an exhaust outlet 134 of the combustion furnace 180 and a drying chamber 113 of the drier 104 extends outside the combustion furnace 180. Further, a drying gas blowoff device 118 is provided that can form a fluid bed by blowing off the drying gas to material under treatment 1 in the drying chamber 113 from below. Thus, the material under treatment 1 can be dried while being agitated in a floating state.
[0056]The drying gas having passed through the drying chamber 113 is stripped of fine particles of the material under treatment and the like in a cyclone separator 119. The dryi...
