Abstract: A gas pressure operated dispensing method and apparatus for dispensing fluids including a first container as a primary fluid source, a second container as a reserve fluid source, a first gas line connected to the first container and a second gas line connected to the second container, a gas pressure source connected to the first and second gas lines for supplying a pressurized gas thereto, a first change over valve and a second change over valve disposed in the first gas line and the second line, respectively, a supply line for introducing a fluid into the second container, a discharge line for discharging a fluid from the first container, a fluid line communicating with the supply line and the second container at one end and the discharge line and the first container at the other end, the fluid line containing a third valve, and vent line selectively connectible to the second gas line through the second change over valve when the gas pressure source is separated from the second gas line by the second change

Abstract: A method of treating bulk goods requiring control of process parameters including moisture content, temperature, and quantity of goods through the use of a process computer. The computer evaluates and continuously monitors and modifies variations in the supply material in relation to a particular mathematical formula. Modification procedures are determined by the process computer and then actuated via the control circuitry.
