Valmet Chip Bin DB is a agitator equipped flat-bottomed chip bin fitted with a screw conveyor for an actively controlled discharge of raw material. The chip bin is suited for wood waste materials that are difficult to feed and have bridging tendencies.

The bin features a slightly conical upper shell narrowing towards the top and with one central and multiple peripheral insertion points for adding steam. The Valmet Chip Bin DB is highly suitable to use for pre-steaming of the chips.
An agitator rotates in full revolutions along the bottom to avoid any stagnant material that may cause unwanted build-ups and bridging problems. The design of the agitator and continuous rotation of agitator are crucial for smooth feeding and even presteaming of the raw material.
The agitator directs the material towards the discharge screw which can be fitted with a dewatering box to further optimize the dewatering performance of the plug screw feeder. This will result in less moisture entering the dryer.
