ABSTRACT:
Apparatus for supplying deaerated stock to a processing machine incorporates an enclosed first receiver and a second receiver open to the atmosphere. Stock deaerated by vacuum in the first receiver flows to the second receiver. Some of such stock spills over a weir associated with the second receiver to maintain a constant-level pond in such receiver. Stock is supplied to the machine from such constant-level pond, so that the pond minimizes stock pressure fluctuations at the machine. The stock spilling over the weir is recycled to the first receiver. During a temporary shutdown of the processing machine, the system may be maintained in operation with continuous recirculation of stock through the receivers to facilitate rapid restarting of the machine. Because there is no need for a pond of stock in the enclosed receiver, such receiver may be compact. The system may be installed in a preexisting mill and space within a preexisting vessel may be used for the second receiver.
