Chip Presteaming | Chip Pre-steaming

The Help storage and pre-steaming bin is designed for the following applications:

• Continuous digesters
• CTMP / TMP / NSSC
• M & D digester
• MDF process
• Pelleting process

The ANDRITZ Help pre-steaming bin delivers an accurate and stable chip flow regardless of the process. Uniform moisture content and air removal prepare the chips for the next process step.

The Help storage bin is a round bin with a circular stoker discharger on a flat bottom. The stoker is driven by hydraulic cylinders allowing an 80° sweep for each of the stoker arms. The reciprocating action of the discharger covers the entire bottom surface of the bin, ensuring uniform plug flow. The discharger feeds the material to a variable pitch discharge screw that meters the material to the process.
