Potatoes, scientifically known as Solanum tuberosum, originated from Peru and Bolivia in South America. Around 1570, our ancestors followed the Spaniards to Spain and Portugal, and later moved to Italy and other parts of Europe. According to relevant information, it is speculated that they may have entered China in the 17th century (late Ming Dynasty) with European and American missionaries. It can be regarded as an imported product, so some places here call it potato, Dutch potato, etc.

In China, potatoes are the fourth largest food crop after corn, rice and wheat. Since 1995, my country's potato planting area and total output have ranked first in the world. In 2014, my country's potato planting area was 5.562 million hectares, and the total output was 94.852 million tons, accounting for 30% and 24% of the world's potato planting area and output respectively, and accounting for 5.2% and 14.8% of my country's total grain planting area and total output respectively. Since 2006, the planting area and total output have been increasing year by year.

Since the founding of new China, the potato industry has been a good development trend. The area yield has increased steadily, from more than 600,000 hm2 in the 1950 s to more than 530 million m2 now. Moreover, the winter fallow fields in the south have further maintained a stable growth momentum, the production layout has been gradually optimized, the area of the main production areas has been continuously expanded, and the ecological advantages have become more obvious. At present, the country has basically formed four potato advantage areas, namely, the three-north single-cropping area, the southwest mixed-cropping area, the central-cropping area, the intercropping area, the area, the area, the area,, A number of large-scale potato processing backbone enterprises have been established in China, such as Inner Mongolia Huaou, Yunnan Runkai, Ningxia North, Sichuan Guangyou and so on. The processed products are gradually expanded and extended from coarse starch: the market system is constantly improved, and a large number of potato wholesale markets with perfect facilities and functions and standardized trading have been built in the main producing areas, including refined starch, modified starch, potato chips, French fries and whole flour, the proportion of processing has increased from 5% in 1999 to 15% at present. The industrial chain has been continuously extended and the market system has been continuously improved. Potato deep processing machines have also emerged. Full-automatic potato chips production line, potato chips cutting machines, steam peeling machines and other machines have emerged. Shanghai Yunwang Technology has seized the opportunity to develop and produce a complete set of equipment for deep processing and production of large quantities of potato chips, especially steam peeling machines, which are deeply loved by customers, shanghai Yunwang Technology focuses on the production and manufacture of large-scale food steam peeling equipment and French fries production line. The company pays attention to the practicality and innovation of the equipment. At present, a number of technologies are under review... At the same time, it has the right to export foreign trade and has obtained ISO 9001, NB, CEASME and other international certification certificates. The French fries production line and steam peeling machine equipment produced by our company have the characteristics of high degree of automation and low labor intensity, which have realized the refinement, continuity and customization of food processing technology to a greater extent.
