Xinhuanet, Yunnan Channel, February 17 (Reporter Ji Zhepeng) In China's largest coffee-producing region, Yunnan, the traditional coffee drying area is insufficient, and rainy weather causes quality problems, which restricts coffee processing. A few days ago, Lingfeng Group of Lincang City, Yunnan Province independently developed “back-pressure hot-air penetration assisted dry coffee†technology and equipment, realized industrialized controllable operation of initial processing of coffee, and obtained a utility model issued by the State Intellectual Property Office. Technical patents have been promoted in some coffee producing areas. Shen Min, deputy general manager of Lingfeng Group, introduced that the group invested more than RMB 10 million and sent a team of experts to inspect and study advanced processing technologies at home and abroad. After optimization and upgrading of drying processes and equipment and repeated improvement, different temperature curves and drying methods were adopted. Repeated comparison tests on the quality of coffee beans. In the end, through integrated innovation, the company independently developed a "back-pressure hot-air penetration assisted dry coffee" technology and equipment. According to reports, Ling Feng's "back-pressure hot-air penetration assisted dry coffee" process and equipment guarantee a balanced and stable quality of coffee beans, a short processing cycle, controllable drying process, free from natural conditions, and save more land than traditional natural drying. The advantages of the new process, such as the need for fewer operators, solve the problems of insufficient drying space, long drying time, reduced quality due to rainy weather, unstable product quality, and excessive labor costs. In the coffee season from 2014 to 2015, Lingfeng’s coffee base will be put into production of about 60,000 mu. There will be 15 coffee processing factories. This new method can be used to process 5,000 tons of dried coffee beans. Seimei introduced that in order to promote the new coffee drying process, Lingfeng Group invested and established Pu'er Lingfeng Coffee Co., Ltd. in July 2014. As of January 2015, Pu'er Lingfeng Company has established 13 dry coffee production facilities in the Pu'er region, producing 100 tons of dry beans per day, which can meet 20,000 tons of coffee production. In more than one month from the 2014 to 2015 production season, Pu'er Lingfeng Company has processed more than 1,000 tons of coffee on behalf of the company. The processing cycle is short and the product quality is stable. It has been recognized by local coffee farmers and distributors and has solved the production area to some extent. The problem of more rain and dampness of coffee beans. At present, the Lingfeng company's coffee drying process is being promoted in the coffee producing area, and the processing plant is now producing at full capacity.
The die casting process involves the use of a furnace, metal, die casting machine, and die.

The metal, typically a non-ferrous alloy such as aluminum, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
