Abstract

The method involves inserting wood chips into a drying container (1), and drawing the wood chips at a lower side over a sliding plate (9). Drying air is supplied from bottom into a double base that is formed as an air cushion (2) with perforated base (11) in the container. The supply and discharge of the wood chips is controlled by maintaining constant dumping height and by continuous program controlled monitoring of parameters e.g. moisture in the wood chips and exhaust gas, where the wood chips are discharged over a chain or spiral milling cutter (4) that rotates around a vertical axis. An independent claim is also included for a device for drying wood chips comprising a supply device that discharges into a cylindrical drying container.
