1. An apparatus for batched mixing of at least a first liquid individual component and a second liquid individual component to form an additive component and to store said additive component, said apparatus being part of a mixer for forming a mixture product by mixing said additive component with a base component, said apparatus comprising a first fluid connection, a first valve, a single-batch tank, a second fluid connection, a mixing-and-buffer tank, a second valve, a master line, and a vacuum source, wherein said first fluid connection is a physical line that connects to a source of said first individual component, wherein said first valve connects said single-batch tank to said first fluid connection, wherein said vacuum source is configured for vacuum-assisted feeding of said first and second individual components into said single-batch tank, and away from said mixing-and-buffer tank, wherein, in operation, said vacuum source causes a pressure difference that urges a component to move away from said mixing-and-buffer tank and toward said single-batch tank, wherein said second fluid connection is a physical line that connects to a source of said second individual component, wherein said master line connects said mixing-and-buffer tank to said single-batch tank, wherein said second valve connects said single-batch tank to said second fluid connection, wherein said mixing-and-buffer tank provides temporary storage of said additive component and is located upstream of where said additive component and said base component are first mixed together, wherein said mixing-and-buffer tank is arranged on a level below said single-batch tank such that said first individual component and said second individual component are discharged in free fall into said mixing-and-buffer tank, wherein, in operation, said first individual component is a liquid that flows through said first fluid connection, wherein, in operation, said second individual component is a liquid that flows through said second fluid connection, wherein, in operation, said first fluid connection supplies said first individual component for mixing to make said additive component, wherein, in operation, said second fluid connection supplies said second individual component for mixing to make said additive component, wherein said first and second fluid connections are connections that are configured for connecting to a source of liquid, and wherein said first valve is selected from the group consisting of a proportioning valve and a control valve. |
