A dryer for a compressed gas provided with a vessel with a drying agent and a drying zone-and a regeneration zone; at least one intermediate zone that, viewed in the direction of rotation of the drum, is situated between the regeneration zone and the drying zone and which is provided with a separate inlet and an outlet that is shared with or connected to the outlet of the regeneration zone; a tap-off pipe that branches off from the outlet of the drying zone and connects to the aforementioned separate inlet of the intermediate zone; one or more blowers in the tap-off pipe for effectuating an intermediate flow from the drying zone, where the dryer is configured such that the entire flow of gas to be dried supplied to the dryer is first guided through the regeneration zone.

A dryer for a compressed gas provided with a vessel with a drying agent and a drying zone and a regeneration zone; at least one intermediate zone that, viewed in the direction of rotation of the drum, is situated between the regeneration zone and the drying zone and which is provided with a separate inlet and an outlet that is shared with or connected to the outlet of the regeneration zone; a tap-off pipe that branches off from the outlet of the drying zone and connects to the aforementioned separate inlet of the intermediate zone; one or more blowers in the tap-off pipe for effectuating an intermediate flow from the drying zone, where the dryer is configured such that the entire flow of gas to be dried supplied to the dryer is first guided through the regeneration zone.

Method for drying a gas which has been compressed by a compressor (1) wherein compressed gas (2) from the compressor is driven through an amount of drying agent (3) until a dried, compressed gas (4) is obtained. An amount of used drying agent (7) is regenerated by driving a part (5) of dried compressed gas (4), which is heated first by the compression heat of compressor (1), through used drying agent (7). Moisture is absorbed from used drying agent (7) by a part (5) of the dried compressed gas (4), which is then condensed and separated by cooling. Part (5) of dried compressed gas (4) is then mixed with compressed gas (2) from the compressor to be dried.
