Abstract

The application relates to a method for recirculating air in a drying process (1), where in the drying process (1) moisture is removed from a product into an air flow creating an exhaust air flow (2a). The exhaust air flow (2a) is guided to a device (3) wherein the moisture content of the exhaust air flow (2a) is reduced. The exhaust air flow (2b-c) exiting the device (3) is divided at least into an air flow (2b) recirculated to the drying process (1) and into an air flow (2c) to at least one room related to the drying process (1). The application also relates to an arrangement for recirculating air in a drying process (1).
