Optoelectronic Double-Wave Method for Remote Control of Vegetable Fiber Moisture

The paper introduces an optoelectronic two-wave method for remote control of raw cotton moisture. To improve the quality of materials obtained from the fiber, it is necessary to proper organize its storage and comply with the optimal modes of processing technology at all stages of production. Proper storage and selection of technological processing depend on the quality indicators of the fiber, namely its moisture. The study shows that currently used methods and devices for the fiber moisture control do not meet the requirements of rapidity and the required measurement accuracy. We found it relevant to develop highly sensitive, accurate and reliable control devices for raw cotton moisture using new high-performance semiconductor radiation sources in the near infrared region. The paper presents a block diagram of an optoelectronic device for remote control of raw cotton moisture. The device uses LED19-PR with a typical maximum emission wavelength of 1.95 µm as radiation sources. The results of remote control of raw cotton moisture are given
