A digester installation eliminates disadvantages such as excessive labor costs. One operator can operate and control the various functions of the charging system from a control room.
Automation is another benefit since the system can easily be remote controleld OR fully automated utilizing simple mechanical or electro/hydraulic components. This provides a controled and uniform management system.
The Jeffrey Rader Digester Charging System provides uniform pulp quality. Pre-heating, preimpregnation, liquor-impregnation and circulation are all elements that also add to the uniform pulp quality.
The Digester Charging System is completely enclosed from the infeed to the point of discharge into the digester. Conveying air is separated in the cyclone and evacuated to atmosphere.
The air evacuation system operated during the chip filling prevents the air and incondensible gasses from disturbing the chip flow pattern. As an additional benefit of this system, all the digester gasses containing mercaptans and other toxic components which otherwise escape to the atmosphere, are collected and can be blown to the recovery boiler or other air pollution control device.
