Inoculant direct injection system

A direct injection supply kit to mix liquid components into a mixture and deliver the mixture to a treatment device, said direct injection supply kit comprising:

• liquid component containers each comprising an interior space configured to receive a corresponding one of the liquid components of the mixture,
• each of said containers including an elongated flexible bladder, which generally defines the interior space, and a discharge nozzle, which fluidly communicates with the interior space to discharge a flow of the corresponding liquid component from the bladder,
• said discharge nozzle including a housing and a nozzle valve shiftably mounted in the housing,
• said nozzle valve being shiftable into and out of a normally closed valve position where the housing and nozzle valve cooperatively prevent fluid flow through the nozzle;
• and
• metering bodies fluidly communicating with respective component containers,
• each of said metering bodies defining a metering orifice to control a flow rate of the corresponding liquid component from the bladder, with at least a pair of the metering bodies presenting dissimilar metering orifices so as to provide distinct flow rates of the corresponding liquid components, and
• each of said metering bodies being removably attached to the corresponding discharge nozzle, with attachment of the metering body to the corresponding discharge nozzle causing the nozzle valve to shift out of the normally closed valve position and thereby permit the flow of the corresponding liquid component from the bladder to the treatment device.
