PROBLEM TO BE SOLVED: To provide a continuous hydroextractor obtained by simplifying and power-saving the structure of a continuous spin drier dehydrating sewage sludge or water purifying sludge, etc. SOLUTION: In the continuous hydroextractor, a filtering room (4) is formed of both an inner cylinder (2) and an outer cylinder (3) on a vertically-installed dewatering cylinder (1), a curved injection tube (5) is connected to the lower end of this dewatering cylinder (1), a guiding cylinder (6) connected with the inner cylinder (2) of the dewatering cylinder (1) is provided on the injection tube (5), an internally-hollowed curved expression tube (9) is connected to the upper end of the dewatering cylinder (1), and a back pressure governor board (11) is allocated on the rear end side of this expression tube (9). The curved injection tube (5) moves in a curved state to provide a cake by shearing action, supporting the vertical attitudinal cake by bending resistance. Then the vertical attitudinal dewatering cylinder (1) receives consolidating action by friction resistance between the force of gravity and the filtering surface to dewater and hollow out the curved expression tube (9) while bearing back pressure from the expression tube (9), and allows the resulting tube (9) to uniformize the variation in moisture content of the cake, to discharge water.
