This year marks a significant turning point in the traditional drying practices of Nanqiao Village, located in Ning'an Township, Zhongning County. For generations, farmers have relied on time-consuming and labor-intensive natural sun-drying methods, which often led to mold, spoilage, and contamination from pests. However, this is changing with the introduction of an innovative solar-powered drying shed developed by local farmer Zeng Baoshan from Baima Township. His invention not only reduces energy consumption but also significantly shortens drying time, minimizes manual labor, and requires less space. This breakthrough effectively addresses long-standing issues such as slow drying, mold growth, and pollution in the region.
Zeng Baoshan, now 61 years old, is affectionately called the "Mechanical Wizard" for his contributions to agricultural machinery. With support from the Autonomous Region Science and Technology Department and the Zhongning County Science and Technology Bureau, he has successfully tested a new hanging-type solar drying shed. This system uses three-dimensional suspension rotary drying technology, along with self-priming and dehumidification, achieving a lighting rate of up to 290%. It can dry 300 kg of fresh pods at once, making the process much more efficient.
In Nanqiao Village, villager Liu Wenzhi shared his experience with reporters. He compared last year’s sun-dried sorghum with the freshly dried product from the solar shed. The latter had larger, plumper grains, a bright red color, and no signs of deformation, while the sun-dried version was dull, discolored, and damaged. Liu said, “The wolfberries dried in the shed are of higher quality and fetch better prices.â€
The innovation has gained widespread attention, especially during this year’s science and technology week in the county. To promote this technology and ease the burden on local farmers, Zhongning County has decided to offer a financial subsidy of 1,300 yuan per drying shed. As of now, nearly 500 sheds have been installed, marking a promising shift toward modern, sustainable agricultural practices.
