Drying is a crucial step in the post-harvest handling of food, as reducing grain moisture to safe levels is essential for long-term storage and preventing spoilage. The effectiveness of the drying process directly affects grain quality, processing performance, and overall food value, which in turn influences agricultural economics, food distribution, and people's daily lives. Recently, a reporter spoke with Dr. Niu Xinghe, a researcher from China Agricultural University and deputy general manager at Zhonggu Group Science and Technology Corporation, about the development and demand for grain drying technology and equipment in China. Reporter: Drying equipment might seem like a small part of the machinery industry, but it plays a vital role in the grain processing sector, especially in improving grain quality and providing high-quality raw materials for the food industry. Could you share your insights on China’s grain drying technology and the current state of its equipment? Niu Xinghe: Developing advanced grain drying technologies and equipment is key to enhancing the competitiveness of China's agricultural products. China has a wide variety of high-moisture crops, such as corn, rice, rapeseed, wheat, and soybeans, with annual production exceeding 40 million tons in normal years. However, during rainy or low-temperature harvest seasons, this number can rise significantly. With the marketization of grain trade, the demand for drying equipment has increased substantially. Since the 1990s, China has used World Bank loans and national funding to build more grain drying facilities. According to recent data, there are 4,647 drying facilities in state-owned warehouses, with a total drying capacity of 39,000 tons per hour. These facilities can dry approximately 44.92 million tons of grain annually. Large-scale equipment is mainly concentrated in the three northeastern provinces, where the drying capacity reaches nearly 30 million tons per year, effectively addressing the issue of insufficient drying capacity in that region. However, challenges remain in China's grain drying equipment industry. While basic research has made progress, it still lags behind global standards. There are many types of machines, but most have limited individual capacity. Grain quality after drying is often poor, with high breakage rates. Many manufacturers focus on imitation rather than innovation, and the technology remains outdated. Regional development is uneven, and overall drying capacity is still insufficient. Reporter: How does China compare to developed countries in terms of grain drying technology and equipment? What are the future trends in domestic grain drying technology? Niu Xinghe: Developed countries like the U.S. and Japan widely use mechanical drying. For example, 75% of U.S. corn and 92% of Japanese rice are dried mechanically. They employ computer simulations to optimize drying processes, ensuring quality while minimizing energy use and maximizing automation. Globally, new drying technologies are emerging to meet diverse needs—such as smart control systems, multi-fuel options, and eco-friendly models. In China, we can expect several trends: a shift from quantity-focused to quality-focused drying methods, the rise of energy-efficient and cost-effective dryers, the development of specialized equipment for soybeans and oilseeds, the integration of intelligent control systems, and the advancement of ventilation and warehouse-based drying techniques. These innovations will shape the future of grain drying in China.

Inflatable Roly Poly

Inflatable roly poly, shaped like humans, animals or other objects, and swing back and forth as soon as it was touched, and then resumed upright. Since it has always been loved by children, now it has become a toy that interacts with customers and uses customers to attract customers during the celebration of commercial super stores.

The inflatable roly poly is because of its convenient transportation, simple operation, softness and not easy to hurt children, and become one of the very favorite Inflatable Toys that are very popular for children or children. Before inflating, it is recommended to spread plastic film on the ground to reduce the contact between the gas mold and the rough ground, which can effectively extend the service life of the gas mold.
