Application case | Application of GY1000 online near-infrared measurement of object moisture content
In daily life and industrial production, whether raw materials, semi-finished products, or finished products, all contain a certain amount of water, such as liquor lees, grain, tobacco, etc. A certain moisture content is of great significance for substances to maintain their shape and properties. For example, in the food field, the moisture content in food will affect the spoilage and moldiness of the food. At the same time, the moisture content in the food has an important relationship with the freshness, hardness, fluidity, flavor and other aspects of the food. The conventional moisture content drying method takes a long time to measure and is cumbersome to measure. It is a quick and simple method to measure the moisture content based on the principle that water absorbs in the near-infrared region.
As a leader in domestic spectroscopy companies, Optosky is committed to developing near-infrared spectroscopy to solve the pain points of moisture content measurement in the industry, and has launched the GY1000 online infrared moisture meter to measure moisture in grain, tobacco, coal and other industries. Provides a fast and convenient method for measuring moisture. Water shows strong absorption characteristics for some specific wavelengths of infrared light. When materials are irradiated with infrared light of specific wavelengths, the water contained in the material will absorb part of the infrared light energy. The more water there is, the more absorption will occur. Therefore, the reduction in reflected light can be measured to calculate the moisture content of the material.
