The development of large scale flour mill in ChinaThe use of large-scale flour mills in China is also the rise of large-scale flour processing industry, and its production equipment has undergone a process of development from foreign countries and independent innovation. In other words, in the 1880s, China's large-scale flour machine equipment was introduced from abroad. Later, with the continuous development and progress of China's flour machine manufacturing industry, after more than 20 years of collision and exchange with western technology, we digested and absorbed the concept of foreign milling, and combined with the characteristics of Chinese traditional noodle cooking food, the system of grinding machine in China. The powder process was boldly reformed, and the wheat processing technology with Chinese characteristics was gradually formed, which promoted the innovation of domestic milling technology.
The development of export flour millIn 1984, the introduction of the 150-ton flour mill production line of Beijing Sino-US Demonstration Flour Mill was the first level of flour production line imported from abroad after the reform and opening up. Subsequently, China imported more than 200 flour machine production lines from the United Kingdom, Switzerland, Italy and other countries, and the number of grinding passes changed slightly. In terms of process design, the United States grinding surface mechanism powder production line equipment configuration is small, the powder road is short, the production capacity is large; the United Kingdom is the opposite, but the quality of flour is slightly better.
However, the flour machine production line imported from abroad has many defects, as follows:
- First, the flour unit consumes a lot of electricity, and the general ton of powder consumes more than 80 kWH.
- Second, the cleaning process design and equipment selection have a simple cleaning process. In the actual production process, the phenomenon that the wheat cleaning effect is poor and the grit content of the flour exceeds the standard is often observed.
- Third, the design of the milling process is often mixed with the wheat varieties in China. The soft wheat is more, the hard wheat is less, the cortex is thicker, and the characteristics of difficult to peel off are not compatible. When processing domestic wheat, in order to ensure the process effect, the yield has to be reduced.
