China's food security alarm has never really been lifted, and the food shortage is gradually expanding. But on the other hand, due to the lack of equipment and facilities, backward technology and other issues, China's grain loss in threshing, drying, storage, transportation and other processes after harvesting is as high as 15%, far exceeding the standard of 5% stipulated by the Food and Agriculture Organization of the United Nations.Печь ионного азотирования
In 2014, the comprehensive mechanization level of crop cultivation and harvesting reached 61%, and China's agricultural production has achieved a historic leap from relying mainly on human and animal resources to agricultural machinery. But at present, the development of Agricultural Mechanization in China is partial and paragraph-like. Not long ago, the Opinion of the Ministry of Agriculture on Promoting the Whole Process Mechanization of Major Crop Production was published. The Opinion focused on improving the mechanization level of six production links, including drying, and solving the problems of mechanical application in weak links such as drying.Вакуумная термическая обработка
On the one hand, the development of drying machinery is the objective demand of ensuring food security and realizing the full and all-round development of Agricultural Mechanization in China. On the other hand, the traditional drying method not only endangers traffic safety but also damages grain quality. With the improvement of land circulation level and the development of new management organizations such as agricultural machinery cooperatives, it has been unable to meet the needs of agricultural production. Muffle furnace is indispensable for high temperature carbonization experiment.Масляная закалка штамповой стали
China's grain drying machinery ushered in a golden period of development. From 2008 to 2010, the amount of domestic dryers increased rapidly with an average annual increase of about 50%. According to incomplete statistics, there are more than 500 domestic drying equipment manufacturers, with annual market sales exceeding 3 billion yuan. However, mechanical drying accounts for only about 1% of the total grain output in China every year. There is still a huge gap between the mechanical drying and the 90% of the total grain output in developed countries.
Gaps mean space for development. Opportunities are often accompanied by risks. How to meet the explosive demand while avoiding risks is a problem worthy of our serious consideration in the dryer industry. Enterprises should become the main body of technological innovation, focus on research and development, improve manufacturing level, master core technology, and produce drying machinery that can meet the needs of users from product quality, technology level and price, which is the key to grasp the golden development period.Термическая обработка стали D2
The inner liner is made of stainless steel plate, and the middle insulation layer is perlite. It has good thermal insulation performance and electric heating. According to the dehydration characteristics of baking materials, different heating power can be selected, which is energy-saving, beautiful, flexible to use, stable performance and easy to transport.
The equipment can be used for the inspection, experiment and aging of electronic, medical and biological products, as well as for baking small quantities of materials.Масляная закалка инструментальной стали
Among many infrared drying methods, infrared radiation heating is the most economical choice for food industry. For example, the muffle oven is essential for filling chocolate, browning on the top and sterilizing bread, drying cereals, wheat and maize, and for the first and second baking of tobacco leaves and high temperature carbonization experiments.Что такое поверхность термообработки
