The quality of rice includes internal and external appearance. The appearance quality mainly includes chalkiness, chalky grain rate, yellow grain and grain type. At present, the appearance quality of rice remains at the level of artificial visual inspection, which is not only poor in objectivity and repeatability, but also time-consuming and labor-intensive to operate, and has low detection accuracy. The introduction of machine vision (also known as computer vision) technology into the appearance quality parameters of rice is one of the effective ways to achieve rapid rice detection. The appearance of rice appearance quality detector in the modern detection of rice quality is worth recommending. Scan WeChat, we met with hate:
Rutile Titanium Dioxide is used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
At the same time, titanium dioxide has a good UV shielding effect, and is often incorporated into textile fibers as a sunscreen. Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is acid and alkali resistant. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.

In the research of rice appearance quality detectors, foreign countries started earlier. At present, there are commercialized instruments and automatic grain quality analyzers. However, these instruments are more expensive and are not suitable for China's national conditions. In China, the research on rice quality testing is still in its infancy, and it mainly stays in the research of detection algorithms. So far, there are no commercially available testing instruments in China.
Through the analysis of the appearance quality meter of rice, it was found that the effective discrimination of chalky rice is the basis for the detection of chalkiness and chalky grain rate. This system uses the method based on artificial neural network to distinguish chalkiness rice. The neural network has distributed storage information and parallel processing. The processing of information has the ability of self-organization and self-learning, which relaxes the constraints required by traditional image recognition methods and can achieve better recognition results. The system uses a three-layer BP network, and the input parameters select chalky size and fractal dimension, which represent the cumulative and distribution information of grayscale in the chalky area respectively; the output parameter is 0 or 1, which represents standard rice and chalky rice respectively. The device has good extensibility, no need to change the system hardware, as long as the method of expanding the system software, you can increase the detection of other appearance quality parameters of rice, such as different varieties of grain, color.

Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrant powder use titanium dioxide instead of lead white and zinc white. You only need to add 5%-8% of titanium dioxide to the fragrance powder to get a permanent white color, making the fragrance smoother, having adhesion, absorption and hiding power. In gouache and cold cream, titanium dioxide can weaken the greasy and transparent feeling. Titanium dioxide can also be used in various other spices, sunscreens, soap flakes, white soap and toothpaste.
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong hiding power.
