Abstract: A storage assembly comprising a tank having a cavity defined by a wall including a sealable port for receiving and storing a perishable organic fluid within the tank, the perishable organic fluid being chilled prior to transfer to the tank; a heat exchange structure at least partially located between an inner and outer wall surface of the wall, wherein prior to receiving the perishable organic fluid the heat exchange structure is configured to chill the cavity; and a sparging structure located within the tank, wherein the sparging structure is in fluid communication with a source of conditioning agent, wherein the sparging structure is configured to: transfer a first portion of the conditioning agent into the tank to purge the tank prior to receiving the perishable organic fluid; and sparge and pressurise the perishable organic fluid with a second portion of the conditioning agent after transfer and sealing within the tank.

Abstract: A mixing system for dissolving water soluble additive into irrigation water employs a venturi system for introduction of water soluble additive into a water stream for injection into a dispersion tank employing low speed contradirectional impellers. Dispersion of the additive through the venturi and gentle yet vigorous agitation in the dispersion tank by contradirectional impellers mixes the additive without shearing of long chain polymers thereby assuring maximum efficacy for the additive solution.
