Abstract
A method for sterilizing liquids, wherein quantities of liquid flowing through at least one reaction chamber are irradiated by at least one UV lamp and are removed after irradiation. The UV lamp continues to be operated for a period Δt1 after removal of the quantity of liquid. A liquid sterilization device comprising at least one UV lamp and at least one reaction chamber through which the liquid to be sterilized flows as well as a tap for removing quantities of liquid. A control and/or regulation device is connected to the tap and to the UV lamp and continues to operate the UV lamp for a period Δt1 once the tap is switched off.
Claims23
A method of sterilizing liquids, comprising the steps of:
- irradiating portions of liquid flowing through at least one reaction chamber by at least one UV lamp having a starting temperature from 15° C. to 20° C. and removing portions of liquid from the reaction chamber after irradiation, wherein liquid at a temperature below the starting temperature of the UV lamp is sterilized, the temperature of the liquid being less than or equal to 12° C., continuing to operate the UV lamp for a period Δt1 after removal of a portion of liquid, and
- selecting the period Δt1 such that the volume of liquid retained in the reaction chamber is warmed up at least to the starting temperature of the UV lamp.
(canceled)
A liquid sterilization device, comprising:
- at least one UV lamp having a starting temperature from 15° C. to 20° C., and comprising at least one reaction chamber through which the liquid flows, the temperature of the liquid being less than or equal to 12° C., and comprising a dispensing device for removing portions of liquid, wherein liquid at a temperature below the starting temperature of the UV lamp flows through the reaction chamber, wherein
- wherein a switching and/or control device is provided which is connected to the dispensing device and to the UV lamp, and that the switching and/or control device continues to operate the UV lamp for a period Δt1 after the switching off of the dispensing device, wherein the period Δt1 is selected such that the volume of liquid retained in the reaction chamber after the dispensing device has been switched off is warmed up to at least the starting temperature of the UV lamp.
