1. A process for producing diesel exhaust fluid, the process comprising:
securing a container comprising a pre-measured quantity of urea into a loading station;
directing, via a system controller, an opening device to form openings in top and bottom surfaces of the container;
directing, via the system controller, a water pump to feed water through the container;
feeding the urea and water into a mixing tank;
directing, via the system controller, a motor to activate to mix the urea and the water in the mixing tank to produce a volume of 1 gallon to 100 gallons of the diesel exhaust fluid; and
directing, via the system controller, one or more diesel exhaust fluid pumps to flow the diesel exhaust fluid in two or more different directions including a first direction in which the diesel exhaust fluid flows directly into a diesel vehicle for use and a second direction in which the diesel exhaust fluid flows into a diesel exhaust fluid holding tank.
