## Abstract

An infrared dehumidifier includes a hollow drum configured to rotate or oscillate around a longitudinal axis and one or more infrared heating lamps disposed inside the drum.

## Claims

### Claim 1

An infrared dehumidifier comprising:
a drum that is hollow and rotatable or configured to oscillate around a longitudinal axis of the drum, the drum being couplable to an inflow duct and to an outflow duct; and
one or more infrared heating lamps disposed within the drum.

### Claim 2 (depends on 1)

The infrared dehumidifier of claim 1, wherein an inner surface of the drum comprises one or projections.

### Claim 3 (depends on 2)

The infrared dehumidifier of claim 2, wherein the one or more projections are disposed in a longitudinal pattern.

### Claim 4 (depends on 2)

The infrared dehumidifier of claim 2, wherein the one or more projections are disposed in a helical pattern.

### Claim 5 (depends on 2)

The infrared dehumidifier of claim 2, wherein the one or more projections comprise a convex surface.

### Claim 6 (depends on 2)

The infrared dehumidifier of claim 2, wherein the one or more projections are fastened to the inner surface of the drum.

### Claim 7 (depends on 1)

The infrared dehumidifier of claim 1, wherein the drum is substantially cylindrical, and wherein bases of the drum are open or openable.

### Claim 8 (depends on 1)

The infrared dehumidifier of claim 1, further comprising one or more movable elements for opening and closing the drum.

### Claim 9 (depends on 8)

The infrared dehumidifier of claim 8, wherein the one or more movable elements comprise one or more translating guides for translating the one or more movable elements.

### Claim 10 (depends on 1)

The infrared dehumidifier of claims 1, wherein a cross section of the drum is shaped as an arc of a circle and oscillates in relation to the longitudinal axis.

### Claim 11 (depends on 1)

The infrared dehumidifier of claim 1, further comprising an inclination device directly or indirectly applied to the drum, wherein the inclination device is configured for raising one side of the drum, thereby regulating an advancement of a material within the drum.

### Claim 12 (depends on 11)

The infrared dehumidifier of claim 11, wherein the inclination device comprises a hydraulic piston.

### Claim 13 (depends on 1)

The infrared dehumidifier of claim 1, further comprising a support frame containing and supporting the drum.
