Potato, scientific name potato, ancestral roots are Peru and Bolivia in South America. Around 1570 AD, our ancestors followed the Spanish to Spain and Portugal, and later traveled to Italy and various parts of Europe. According to relevant information, it is speculated that in the 17th century (late Ming Dynasty), it may have followed European and American missionaries into China, which can be considered a type of imported potato. Therefore, some places here are called potatoes, Dutch potatoes, etc.

In China, potatoes are also the fourth largest cereal crop after corn, rice, and wheat. Since 1995, China has ranked first in the world in terms of potato planting area and total output. In 2014, the potato planting area in China was 5.562 million hectares, with a total output of 94.852 million tons, accounting for 30% and 24% of the world's potato planting area and output, respectively. The proportion of China's total grain planting area and total output was 5.2% and 14.8%, respectively. Since 2006, the planting area and total yield have shown an increasing trend year by year.

Since the establishment of the People's Republic of China, the potato industry has been showing a good development trend. The area and yield have steadily increased, from over 600000 hectares in the 1950s to over 5.3 million hectares now. Moreover, by utilizing the winter fallow fields in the south, the stable growth momentum has been further maintained, and the production layout has gradually been optimized. The main production area continues to expand, and the ecological advantages have become clearerCurrently, there are four major potato advantage areas in China, including the Three North Single Crop Area, Southwest Mixed Crop Area, Central Plains Inter Crop Area, and Southern Winter Crop Area. The processing industry is flourishing, and a number of large potato processing backbone enterprises have been established in Inner Mongolia Huaou, Yunnan Runkai, Ningxia North, Sichuan Guangyou, etc. The processing products have gradually expanded and extended from crude starch: the market system is constantly improving, and a large number of well-equipped and standardized Ma Ling Zhu wholesale markets have been built in the main production areas, to deep processing products such as refined starch, modified starch, potato chips, French fries, and whole flour. The processing proportion has increased from 5% in 1999 to 15% at present. The industrial chain continues to extend and the market system is constantly improving. Potato deep processing machines have also emerged, and fully automatic potato chips have emerged. Production lines, french fries and potato chips cutting machines, steam peeling machines, and other equipment are constantly emerging, Shanghai Yunwang Technology seized the opportunity to develop and produce a complete set of equipment for deep processing and production of large quantities of french fries and chips, especially the steam peeling machine, which is highly favored by customers. Shanghai Yunwang Technology focuses on the production and manufacturing of large-scale food steam peeling equipment and french fry production lines. The company focuses on the practicality and innovation of equipment, and currently has multiple technologies under review; … Simultaneously possessing the right to export foreign trade and obtaining international certifications such as ISO 9001, NB, CEASE, etc. Our company's french fry production line and steam peeler equipment have the characteristics of high automation and low labor intensity, which greatly realizes the refinement, continuity, and customization of food processing technology.
