Abstract (en)
[origin: EP1707270A1] Unit (1) for treatment of organic waste having a waste sorting means comprising a sieve (21) movable between a first position, where it allows the passage of only a waste liquid fraction, and A second position, where it allows the passage also of a waste solid fraction. The sieve (21) is operatively connected by a rod (20) to a control valve (30), arranged downstream of a grinding chamber (10), in order to synchronize its movements. The valve (30) has a diaphragm (31) having holes (32) and a dividing wall (33) parallel to it. In a first position of the sieve (21) the valve (30) has the pierced diaphragm (31) arranged at the base of the grinding chamber (10) and the dividing wall (33) faces the outlet (35). This way, in a first step of organic waste treatment, the waste liquid fraction can outflow up to a water drain, which is in hydraulic connection with the unit (1) by a duct (35). A second step of organic waste treatment provides the arrangement of the the sieve (21) in the second position in order to cause the solid fraction of the waste processed to reach the grinding chamber (10), where it is finely ground. In particular, in the grinding chamber knives (15) are arranged on the boundary of a rotating drum (11) that cooperate with a stationary knife (16) connected to the wall of the chamber (10) in order to provide a substantially "comb-shaped" structure.
