A liquid ejection apparatus comprising a fluid line configured to extend into a tank and to receive a liquid, a rotary head being arranged on the pipe and fitted with a rotary hub that comprises a liquid ejection nozzle for ejecting the liquid, the rotary head being rotatable in a first direction and the rotary hub being rotatable in a second direction, such that the liquid ejected by the nozzle is ejected in a pattern on an interior surface of the tank. The liquid ejection nozzle comprises a first liquid outlet capable of ejecting the liquid in a first direction towards the interior surface of the tank, and a second liquid outlet capable of ejecting the liquid in a second direction towards the interior surface of the tank. 1. A liquid ejection apparatus comprising a fluid line configured to extend into a tank and to receive a liquid , a rotary head being arranged on the fluid line and fitted with a rotary hub that comprises a liquid ejection nozzle for ejecting the liquid , the rotary head being rotatable in a first direction about a first geometrical axis and the rotary hub being rotatable in a second direction about a second geometrical axis that is offset from the first geometrical axis , such that the liquid ejected by the nozzle is ejected in a pattern towards an interior surface of the tank , wherein the liquid ejection nozzle comprisesa first liquid outlet arranged to eject the liquid in a first direction towards the interior surface of the tank, anda second liquid outlet arranged to eject the liquid in a second direction towards the interior surface of the tank, which second direction is inclined to the second geometrical axis by an angle of 10° to 80°.2. A liquid ejection apparatus according to claim 1 , wherein the second direction is directed away from the first geometrical axis at all times during a rotation of the rotary hub about the second geometrical axis.3. A liquid ejection apparatus according to claim 1 , wherein the second direction is inclined ...
