Abstract
The solid-liquid separating device 10 is capable of separating a concentrated liquid from a slurry by centrifugation and includes a centrifugation unit 12 having a rotating vessel 15 with a porous outer wall surface through which liquid is transmissible and a heater unit 18. Preferably, a portion of the slurry to be treated that is closest to a central axis of rotation of the centrifugation unit 12 is heated by the heater unit 18 during the centrifugation.
Claims23
A solid-liquid separating device adapted to separate a liquid from a slurry containing ice and liquid by centrifugation, comprising:
- a rotor unit including a rotating vessel having a porous outer wall surface through which liquids can be transmitted, the rotating vessel having a rotational axis;
- and
- an electrical heating unit disposed proximately to the rotational axis of the rotating vessel, wherein the electrical heating unit is constructed and arranged such that radiated heat from the electrical heating unit melts a portion of the ice within the slurry that is disposed closest to the rotational axis of the rotating vessel during centrifugation.
An apparatus, comprising:
- a stationary rotor housing;
- a rotor unit rotatably disposed within the rotor housing, the rotor unit having a rotational axis and comprising a rotating vessel having a porous outer wall surface, the rotating vessel being constructed and arranged to receive a slurry containing ice and liquid;
- and
- means for heating a portion of the slurry that is proximal to the rotational axis of the rotor unit by converting electrical power into radiated heat and without introducing any foreign substances into the slurry.
