Grain dryers become the first choice for large grain producers
People use food as their day, and in the rainy season, grain dryers have become the first choice for large grain producers. Under the guidance of the national food security strategy, emerging agricultural cooperatives such as agricultural cooperatives, family farms, large grain producers, and grain processing enterprises, which are mainly engaged in grain production, will be unprecedentedly developed in quantity and quality, and China will follow. The grain dryer market has grown rapidly. After more than 10 years of ups and downs, China's grain dryers have grown from the initial 36,000 units to more than 100,000 units, and the annual sales volume has increased from about 3,000 units at the beginning to nearly 8,000 units. The increasing numbers not only represent The development of the market also represents the process of people knowing and using the food dryer. At present, China's grain dryer equipment market is facing good opportunities for development, mainly in three aspects. First, the policy environment is favorable. The state attaches great importance to the production and promotion of grain dryer equipment. The second is that there are many kinds of drying machinery on the market, and there are practical new types of machinery and technical service support that can be selected for promotion. The third is the rapid promotion of the combine harvester and the mode of cross-regional operation, so that a large number of grains need to be dried quickly and quickly.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
