Abstract

Drying device (1) comprising a drying medium (2) with a predetermined number of drying segments (3a, 3b,... 3f) which extend adjacently of each other and are associated with at least one opening (8) at each of a first connecting end (4) and a second connecting end (5), wherein the predetermined number is greater than six and wherein each connecting end comprises first and second complementary concentric elements which are rotatable relative to each other round an axis (9), wherein the openings are provided in the first concentric elements along a rotation ring around the axis, wherein the second concentric elements each delimit at least two channels (10A, 10B) which open at the position of said rotation ring, so that corresponding channels of the first and second connecting end are connected to each other via the openings and the drying segments in order to allow a first airflow and a second airflow through the drying device.

5. The drying device according to any one of the preceding , wherein the predetermined number is smaller than 50.
6. The drying device according to claim 5, wherein the predetermined number is 5 smaller than 40.
7. The drying device according to claim 6, wherein the predetermined number is smaller than 30. 10
8. The drying device according to any one of claims 5 to 7, wherein the predetermined number is greater than 10.
9. The drying device according to claim 8, wherein the predetermined number is greater than 15.
10. The drying device according to claim 9, wherein the ermined number is greater than 20.
11. The drying device according to any one of the preceding claims, wherein the two 20 channels are provided for allowing the first airflow to flow through X segments and for allowing the second airflow to flow through Y segments, n X is r than Y.
12. The drying device according to any one of the preceding , wherein the drying device is provided for allowing the first w and the second airflow in opposite 25 ions.
13. The drying device according to the preceding claim, wherein the device is formed to allow a third airflow which extends between an end of the first airflow on the one side and an end of the second airflow on the other.
14. The drying device according to any one of claims 11 to 13, wherein the two channels are provided for allowing the third airflow to flow through Z segments, wherein Z is smaller than Y.
15. The drying device according to any one of the preceding claims, wherein each drying segment has an air chamber on either side of the drying medium in order to distribute air among the at least one opening and the drying medium. 5
16. Compressor for compressing a gas, which compressor is provided with at least one compressor t with an outlet for compressed gas, wherein said outlet for ssed gas is connected to the drying device according to any one of the preceding claims. FiG 1E1) FIG 2 FIG 3 Fi? LEA FEE lie-B HE» S FIG 7a
