Method for thermally disinfecting a centrifuge
A method for thermally disinfecting a centrifuge to reduce the quantity of germs therein, the centrifuge having a rotatable drum and being used for centrifugally processing a product, involves reducing the quantity of germs using vapor that is not pressurized or which is at atmospheric pressure.
1. A method for thermally disinfecting a centrifuge by reducing a quantity of germs in the centrifuge, the method comprising:
reducing the quantity of gems in the centrifuge using vapor that is not pressurized or which is at atmospheric pressure,
wherein the centrifuge has a rotatable drum and is configured to centrifugally processing a product,
wherein the vapor is passed through a feed, distributor ducts, a centrifuging chamber, a separating disk stack, and an outlet of the centrifuge,
wherein, while the vapor is passed through the centrifuge, the drum is rotated at a speed below an operating speed of the centrifuge during centrifugal processing of the product and which is set to a lowest possible value at which penetration of vapor into a drive chamber of the centrifuge is prevented, and
wherein the method further comprises measuring air humidity in the drive chamber.
2. The method of claim 1 , wherein the vapor is steam under atmospheric pressure.
3. The method of claim 1 , wherein the vapor under atmospheric pressure is passed via a product path of the centrifuge.
4. The method of claim 1 , wherein the drum is rotated as the vapor is passed through the centrifuge.
5. The method of claim 1 , wherein the vapor is also passed through outlet openings, a hood, or a solids trap of the centrifuge.
6. The method of claim 1 , further comprising:
measuring, at one or more measurement locations, effectively achieved temperatures.
7. The method of claim 6 , wherein the effectively achieved temperatures are measured at the one or more measurement locations by using one or more temperature sensors, wherein the measurement locations are
an inlet of the centrifuge,
an outlet line of the centrifuge,
a frame outlet of the centrifuge,
a hood of the centrifuge, or
a solids trap of the centrifuge.
8. The method of claim 6 , wherein the method is performed out until a predetermined minimum temperature has been achieved for a predetermined time period at one, a plurality of, or all of the temperature sensors.
9. A method for thermally disinfecting a centrifuge by reducing a quantity of germs in the centrifuge, the method comprising:
reducing the quantity of gems in the centrifuge using vapor that is not pressurized or which is at atmospheric pressure,
wherein the centrifuge has a rotatable drum and is configured to centrifugally processing a product,
wherein the vapor is passed through a feed, distributor ducts, a centrifuging chamber, a separating disk stack, and an outlet of the centrifuge,
wherein, while the vapor is passed through the centrifuge, the drum is rotated at a speed below an operating speed of the centrifuge during centrifugal processing of the product and which is set to a lowest possible value at which penetration of vapor into a drive chamber of the centrifuge is prevented, and
wherein the method further comprises measuring water content in a lubricating oil in a lubricant system of the centrifuge.
10. The method of claim 9 , wherein the vapor is steam under atmospheric pressure.
11. The method of claim 9 , wherein the vapor under atmospheric pressure is passed via a product path of the centrifuge.
12. The method of claim 9 , wherein the drum is rotated as the vapor is passed through the centrifuge.
13. The method of claim 9 , wherein the vapor is also passed through outlet openings, a hood, or a solids trap of the centrifuge.
14. The method of claim 9 , further comprising:
measuring, at one or more measurement locations, effectively achieved temperatures.
15. The method of claim 14 , wherein the effectively achieved temperatures are measured at the one or more measurement locations by using one or more temperature sensors, wherein the measurement locations are
an inlet of the centrifuge,
an outlet line of the centrifuge,
a frame outlet of the centrifuge,
a hood of the centrifuge, or
a solids trap of the centrifuge.
16. The method of claim 14 , wherein the method is performed out until a predetermined minimum temperature has been achieved for a predetermined time period at one, a plurality of, or all of the temperature sensors.
