Solution Overview
Problem
Existing drying devices for compressed gas suffer from inefficient distribution between drying and regeneration air flows, leading to complex and costly constructions that are difficult to maintain.
Innovation Solution
A drying device with a drying medium segmented into multiple adjacently positioned segments, each associated with complementary concentric elements that allow for optimal distribution of air flows through channels, using a static configuration to simplify construction and maintenance while enhancing efficiency.

1Productivity
If a rotation dryer with a cylindrical drying medium is used, then the distribution between drying and regeneration air flows can be achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The drying medium is divided into multiple drying segments (more than six) arranged adjacently, with each segment associated with openings in concentric elements. This segmentation allows optimized distribution of drying and regeneration air flows through selective opening configurations, achieving efficient drying while maintaining a simpler static structure compared to rotating cylindrical designs.
Solution Approach 2:
Instead of rotating the drying medium as in conventional rotation dryers, the patent inverts the approach by making the drying medium static and using rotatable concentric elements with openings to achieve the necessary airflow distribution. This inversion simplifies the overall construction while maintaining drying effectiveness.
2Productivity
If traditional connecting methods for drying drum and air distributing element are used, then air flow distribution is achieved, but maintenance difficulty and cost increase
Solution Approach 1:
The connecting ends are divided into first and second complementary concentric elements that can be independently configured and maintained. Each element has openings that can be selectively positioned to control airflow distribution, allowing for simplified maintenance and replacement of individual components rather than the entire assembly.
Solution Approach 2:
The concentric elements are designed to be rotatable relative to each other, allowing dynamic adjustment of the opening configurations to optimize airflow distribution between drying and regeneration modes. This dynamic capability is achieved through simple rotational movement rather than complex mechanical connections, improving maintainability.

AI summary
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.
