System and method for ejecting liquid into a container for mixing and cleaning purposes

A method for ejecting liquid in a container, the method performed by a system comprising a mixer having an inlet for receiving liquid, and a rotary head fitted with a nozzle for ejecting liquid into the container, at least one drive member for rotating the rotary head about at least one axis such that liquid is ejected into the container in a predetermined pattern, a processing unit, and a memory unit in which is stored a plurality of different operation parameters, each operation parameter being associated with an operation that is either mixing liquid content in the container or cleaning an inner surface of the container, and a type of a liquid content to be mixed in the container or cleaned off from the inner surface of the container, the method comprising

• receiving a first one of the operation parameters representative of mixing of a liquid content of the container when the rotary head is submersed in the liquid content,
• controlling the drive member in response to the first operation parameter, such that liquid is ejected into the container in a first predetermined pattern and mixing of the liquid content is effected,
• receiving a second one of the operation parameters representative of cleaning of the inner surface of the container after the liquid content is expelled from the container, the second one of the operation parameters being different from the first one of the operation parameters and
• controlling the drive member in response to the second operation parameter, such that liquid is ejected into the container in a second predetermined pattern and cleaning of the inner surface of the container is effected.

A system configured to eject liquid into a container possessing an inner surface to mix or clean the container, the system comprising:

• a mixer comprising an inlet connectable to a pump for receiving liquid, and a rotary head fitted with a nozzle for ejecting liquid into the container;
• a motor operatively connected to the rotary head for rotating the rotary head about at least one axis such that liquid is ejected into the container;
• a processing unit;
• memory in which is stored a plurality of different operation parameters, each stored operation parameter being associated with:
• i) a mixing operation in which the liquid in the container is mixed or a cleaning operation in which the inner surface of the container is cleaned;
• and ii) a type of a liquid to be mixed or cleaned off from the inner surface of the container;
• the plurality of different operation parameters stored in the memory including one operation parameter identifying a first mixing operation for a first type of liquid so that the first type of liquid is mixed according to a first set of parameters, the first set of parameters including a first rotation speed of the motor and a first flow rate of the pump;
• the plurality of different operation parameters stored in the memory also including a second operation parameter identifying a second mixing operation for a second type of liquid so that the second type of liquid is mixed according to a second set of parameters, the second set of parameters including a second rotation speed of the motor and a second flow rate of the pump, the second rotation speed of the motor being different from the first rotation speed of the motor, the second flow rate of the pump being different from the first flow rate of the pump, the second type of liquid being different from the first type of liquid;
• and
• the plurality of different operation parameters stored in the memory also including a third operation parameter identifying a cleaning operation for the first type of liquid so that the first type of liquid is cleaned off the inner surface of the container according to a third set of parameters, the third set of parameters including a third rotation speed of the motor and a third flow rate of the pump, the third rotation speed of the motor being different from the first rotation speed of the motor, the third flow rate of the pump being different from the first flow rate of the pump.
