China's drying nets Guangxi's late rice harvest is now completed, but the rice farmers still scratch the head of the lack of drying machinery and scientific drying techniques, and rice is still heavily dependent on the sun in the sun. In the national food production county in Guiping City, Guangxi, the reporter heard that some grain producers reported that during the harvest period last year, they encountered rain and continuous weather, causing the rice to be unable to dry. They watched Feng Shui’s rice mold rot and the farmers were both distressed and distressed. .
Li Wenzhao, who has won the title of National Grain Miller, said: “Last more than 1,000 acres of rice was planted last year and more than 700 tons of grain was produced. However, in the face of a bumper crop, I was caught in a brow, because a large number of paddy rice that had just been harvested met with rain. Continuous weather, unable to dry, difficult to threshing, helplessly watched rotten 20,000 jins, really distressed dead!"
Liu Huaming, deputy director of the Agricultural Bureau of Guiping City, said: “The first drying rice field requires a relatively large site, the second is the need to pay for labor, but also relatively hard, even if the weather is fine, it takes three or four days to dry. Early rice harvest time, rice moisture content Higher, it is easy to get hot and bad when it is not dry in rainy days.â€
Although the traditional natural drying is time-consuming and laborious, but also subject to many factors such as weather, manpower, and drying fields, due to factors such as cost and utilization, the promotion of rice drying machinery in rural areas is relatively slow. The reason for this is the large investment in drying machinery, which increases the cost of rice. According to the farmer Li Wenzhao, the drying of 1 pound of rice will virtually increase the cost of 0.2-0.3 yuan. Buying a dryer will only be idle for a few days during rice harvesting, and it will be idle for long periods of time. As a result, the price of drying machinery will be high, and farmers will be discouraged. On the other hand, the current development of domestic drying machinery technology is slow and cannot meet the needs of modern agricultural production. Although there are drying machines in rural areas, most farmers report that rice drying equipment has many defects, such as poor drying performance, low drying efficiency, poor drying quality, difficulty in handling, and easy-to-failure problems. .
According to the current situation of paddy drying machinery in the market and the needs of rural agricultural production, rice farmers, especially large grain producers, recommend that: First, we hope that the relevant national departments will organize the research team as soon as possible to develop low-cost, easy-to-use, and efficient-use drying machinery and equipment. . The second is to develop a multi-functional mobile drying equipment. Such as in Guangxi, can not only dry rice, but also dry longan, chestnuts, etc., to solve the shortcomings of the use of drying equipment, often idle shortcomings, "a machine more energy," thereby reducing the cost of purchase. Third, the state should increase purchase subsidies for paddy drying equipment. Because most of the main rice producing areas are in the south, the weather in the south is more humid and the rice harvest period is short. In the event of rainy weather, large grain producers will suffer losses. Fourth, the government of the main rice-producing region needs to encourage farmers with financial strength to establish a rice drying service organization. Because the rice drying temperature control technology is relatively strict, low temperature can not afford to lose grain, too high will make the rice lose its original flavor, so a family to engage in drying is difficult to master the technology, with professional service organizations, can train professional and technical personnel, Provide quality services for each household.
The Output Coupler usually has reflectance in the range 40% to 70%. In order to optimize power and spatial profile of the laser beam, the output coupler and end Mirror have optical surfaces with well-defined radii of curvature.Output coupler (OC) is a partially reflecting dielectric mirror used in a laser cavity. It has a function to transmit a part of intracavity optical power in order to get a lasing.
Laser Output Couplers often require a slightly wedged substrate to eliminate interference from multiple reflections inside the component. If you require a specific wedge value, please specify this when ordering.
Total Reflector and Output Coupler are the key optical components in the laser cavity, are a part of the laser process.
Output Couplers are commonly used as laser output coupler or beam attenuator.Laser output couplers often require a slightly wedged substrate to eliminate interference from multiple reflections inside the component
Output coupler (OC) is a partially reflecting Dielectric Mirror used in a laser cavity. It has a function to transmit a part of intracavity optical power in order to get a lasing. Output couplers listed below can be found in stable resonators, as they have a spatially constant reflection/transmission (R/T) value, which is the main property of such kind of mirror. Such cavity's parameters as pump power threshold, maximum output power and laser efficiency highly depends on R/T ratio of output coupler.
We could provide 70%R30T, 65%R35T,60%R40%T ect
