Abstract

A process for producing absorbent materials includes reducing a banana tree stalk into separated fibers, pressing the separated fibers to generate pressed fibers having less than 50% moisture content by weight, reducing moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers, and applying a non-thermal drying process to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

Claims

1. A system for producing absorbent materials, the system comprising:

a reducer configured to reduce a banana tree stalk into separated fibers;

a press configured to press the separated fibers to generate pressed fibers having less than 50% moisture content by weight;

an infrared heating device configured to reduce moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers;

a non-thermal dryer configured to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons, wherein the non-thermal dryer is separate from the infrared heating device and is configured to generate dried fibers after the infrared heating device produces pre-dried fibers; and

a mesh configured to process dried fibers as the dried fibers pass therethrough, wherein a size of the mesh dictates a corresponding size of the processed dried fibers allowed to pass through the mesh.

2. The system of claim 1, wherein the press comprises a hydraulic press, a screw press or a belt press configured to remove water, latex, or natural juices from the separated fibers.

3. The system of claim 1, wherein the press is configured to generate pressed fibers having opened capillaries for absorption of hydrocarbons.

4. The system of claim 1, further comprising a wash assembly for washing the fibers after the separated fibers are pressed.

5. The system of claim 1, wherein the infrared heating device comprises a halogen lamp and a conveyor device.

6. The system of claim 1, further comprising a conveyor device disposed between one or more of the reducer, the press, the infrared heating device and the non-thermal dryer.

7. The system of claim 1, wherein the non-thermal dryer comprises a non-thermal, kinetic disintegration, pulverization device.

8. The system of claim 1, wherein the non-thermal dryer is configured to generate the dried fibers using kinetic energy and airflow, without a heat source.

9. The system of claim 1, wherein the processed dried fibers are integrated into one or more of a loose absorbent material, a wipe, a rag, a towel, a pillow or a boom.
