Yangzhou University students successfully developed a solar vacuum drying device
Elbow Laser Cutting Machine:
6. The main part of the machine tool is the main part of the whole elbow pipe cutting machine. The cutting function and cutting accuracy of the elbow pipe cutting machine are realized by the main machine part. It is composed of the mechanism and the top positive slag extraction mechanism, auxiliary system (lubrication, gas circuit and water circuit), electric control cabinet, operation screen, operation panel and other parts.
7. The patented design of the mold can solve the industry pain points of poor positioning, unstable clamping and poor cutting accuracy. The clamping is not loose. And the cutting accuracy is high.
8. High adaptability: It has a variety of optical fiber interfaces and is compatible with various mainstream lasers.

The drying and dehydration of traditional agricultural and sideline products is the use of boilers to heat water above 100 degrees Celsius to form superheated steam, and then use steam as medium to heat and dehydrate the vegetables in the drying room. This dehydration method not only consumes a large amount of fuel, but also has low energy utilization efficiency. The fuel also generates a large amount of polluting gases during the combustion process. In particular, the temperature of agricultural and sideline products themselves is high during the dehydration process, and vitamins and other nutrients therein have been destroyed.
Can we use advanced technology to use solar energy to dehydrate vegetables? Such a topic triggered the attention of 4 students including Ma Teng, Yang Da Institute of Mechanical Engineering. Through many experiments and improvements, this topic finally achieved results during this summer social practice. The newly developed new dewatering device is to dewater agricultural and sideline products in a quasi-vacuum environment. When in use, the air pressure in the drying chamber is first pumped to below 100 Pa using a vacuum pump. In this state, the water in the vegetables can boil and evaporate as soon as it reaches 30 degrees Celsius. The heat collected by the solar collector plate is then transferred to a drying chamber using a heat pipe to achieve low temperature dehydration. This dewatering device only needs to supply working energy to a vacuum pump with a power of around 370 W. All other sources use solar energy sources and have extremely low energy consumption, especially dehydration at low temperatures, and effectively maintain the nutrient content of dehydrated vegetables.
This scientific research achievement integrates new technologies such as solar heat collection, heat pipe heat exchange, and vacuum low temperature drying, which has opened up a new path for the use of solar energy. At present, this technology has already applied for a patent.
