At the ceremony, the leader of Shenyang City unveiled the “Public R&D Promotion Center in Shenyang Tiexi Equipment Manufacturing Industry Cluster Areaâ€. National Development and Reform Commission, Ministry of Education, Ministry of Science and Technology, Ministry of Industry and Information Technology and other national ministries and leaders attended the signing ceremony. Shenyang Machine Tool Group and TBEA Shenke Group signed a project cooperation agreement with Shenyang University of Technology.
According to reports, at present there are 404 large-scale equipment manufacturing companies in Tiexi District. There are 100 categories, more than 1,000 series, and nearly 10,000 kinds of products are born here and go to the world. Among the 77 major products in the fields of CNC machine tools, power transmission and transformation, large-scale construction machinery, metallurgical mining, petrochemical equipment and other major national technical and equipment industries and major product areas, Tiexi District has a market share of 44 products in the domestic market. Ranked first in the industry, with 18 products listed in the top 10 in the world. The aggregation effect and scale effect of equipment manufacturing have basically taken shape.
Under the background of the rise of the industrial development plan of the Tiexi Equipment Manufacturing Industry Cluster in Shenyang to the national strategy, under the guidance of the goal of building Tiexi into an internationally competitive advanced equipment manufacturing base, Shenyang City is actively building public manufacturing and public facilities. The five platforms of R&D, financial services, modern logistics, and talent cultivation have established a quick channel for Tiexi equipment manufacturing to reach the international market. At present, seven state-level enterprise technology centers, 23 provincial-level enterprise technology centers, Tsinghua ITRI North Center, and two state key laboratories such as high-end CNC machine tools and full-surface boring machines have already settled in Tiexi. There are also research institutes such as Shenyang University of Technology, School of Chemical Engineering, Foundry Research Institute, and Research Institute of Chemical Industry.
In order to meet the demand for public R&D in the industrial development of gathering areas, the public R&D promotion center of Shenyang Tiexi equipment manufacturing industry gathering area came into being. The center, as a government-sponsored platform for companies to provide public R&D services, fully integrates the resources of governments, schools, scientific research institutions, and companies to optimize the allocation of resources, and enhances Sifang’s comprehensive innovation capabilities in a market-based manner. . According to the product strategy and product structure, the company puts forward scientific research and development projects and topics. The center conducts specific project demonstration and puts it on a national and global platform for scientific research. The establishment of the center will help promote the innovation and development of common technologies and key technologies in the Tiexi equipment manufacturing industry in Shenyang, as well as the formation of new advantages, and will strongly promote the overall strength of Shenyang equipment manufacturing industry.
The whole coffee beans are ground, also known as milling, to facilitate the brewing process.
The fineness of the grind strongly affects brewing. Brewing methods that expose coffee grounds to heated water for longer require a coarser grind than faster brewing methods. Beans that are too finely ground for the brewing method in which they are used will expose too much surface area to the heated water and produce a bitter, harsh, "over-extracted" taste. At the other extreme, an overly coarse grind will produce weak coffee unless more is used. Due to the importance of a grind's fineness, a uniform grind is highly desirable.
If a brewing method is used in which the time of exposure of the ground coffee to the heated water is adjustable, then a short brewing time can be used for finely ground coffee. This produces coffee of equal flavor yet uses less ground coffee. A blade grinder does not cause frictional heat buildup in the ground coffee unless used to grind very large amounts as in a commercial operation. A fine grind allows the most efficient extraction but coffee ground too finely will slow down filtration or screening.
Ground coffee deteriorates faster than roasted beans because of the greater surface area exposed to oxygen. Many coffee drinkers grind the beans themselves immediately before brewing.
Spent coffee grinds can be reused for hair care or skin care as well as in the garden. These can also be used as biodiesel fuel.
There are four methods of grinding coffee for brewing: burr-grinding, chopping, pounding, and roller grinding.
