Abstract
A continuous centrifuge includes: a cylindrical rotor configured to separate a specimen; a centrifuging chamber accommodating the rotor; a driving unit configured to rotate the rotor; a specimen line configured to continuously supply and discharge the specimen to and from the rotor during rotation of the rotor; and a controller configured to control the driving unit. The control unit has a cleansing mode which flows a liquid chemical through the specimen line so as to conduct sterilization and/or cleansing while rotating the rotor.
Claims14
A continuous centrifuge comprising:
- a cylindrical rotor configured to separate a specimen;
- a centrifuging chamber accommodating the rotor;
- a driving unit configured to rotate the rotor;
- a specimen line configured to continuously supply and discharge the specimen to and from the rotor during rotation of the rotor, the specimen line including a pump configured to supply the specimen to the rotor and a valve configured to switch a flowing direction of liquid flowing through the specimen line;
- and
- a controller configured to control the driving unit,
- wherein the controller has a cleansing mode which flows a liquid chemical from a liquid chemical source through the specimen line so as to conduct sterilization and/or cleansing while rotating the rotor,
- wherein in the cleansing mode, the controller (i) controls the driving unit to rotate the rotor, (ii) controls the pump to flow the liquid chemical from a liquid chemical source and (iii) controls the valve to switch the flowing direction of the liquid chemical.

A continuous centrifuge comprising:
- a cylindrical rotor configured to separate a specimen;
- a centrifuging chamber accommodating the rotor;
- a driving unit configured to rotate the rotor;
- a specimen line configured to continuously supply and discharge the specimen to and from the rotor during rotation of the rotor, the specimen line including an upper specimen line and a lower specimen line, a pump configured to supply the specimen to the rotor and a valve configured to switch a flowing direction of liquid flowing through the specimen line;
- and
- a controller configured to control the driving unit,
- wherein the controller has a cleansing mode which flows a liquid chemical from a liquid chemical source through the specimen line so as to conduct sterilization and/or cleansing while rotating the rotor, and
- wherein in the cleansing mode, the controller (i) controls the driving unit to rotate the rotor, (ii) controls the pump to flow the liquid chemical from a liquid chemical source and (iii) controls the valve to switch the flowing direction of the liquid chemical from one of the upper specimen line and the lower specimen line.

- a specimen line configured to continuously supply and discharge the specimen to and from the rotor during rotation of the rotor, the specimen line including a pump configured to supply the specimen to the rotor and a valve configured to switch a flowing direction of liquid flowing through the specimen line;
- and
- a controller configured to control the driving unit,
- wherein the controller has a general centrifuging operation mode which flows the specimen through the specimen line and controls the driving unit to rotate the rotor at a first speed so as to separate the specimen, and a cleansing mode which flows a liquid chemical from a liquid chemical source through the specimen line and rotates the rotor at a second speed which is 1/10 or less of the first speed so as to conduct sterilization and/or cleansing while rotating the rotor,
- wherein in the cleaning mode, the controller (i) controls the driving unit to rotate the rotor, (ii) controls the pump to flow the liquid chemical from a liquid chemical source and (iii) controls the valve to switch the flowing direction of the liquid chemical.
