Grain drying equipment and grain and oil processing machinery technology development seminar held in Zhengzhou

Huang Junqiang emphasized in the report titled “Analysis of the Status Quo and Development Trends of China's Grain Dryers” that China is the world’s largest food production and consumption country, with an annual total grain production of 600 million tons. Every year, about 5% of the grain can be lost due to the humid climate, the moisture in the wet valley, or the failure to achieve safe moisture. If you eat 1 pound of food per person per day, you can use up to 82,000 people a year. Therefore, it is imminent to develop a grain drying technology and change the passive situation of the traditional relying on heaven. Huang Junqiang believes that the development trend of China's grain drying technology is mainly divided into three aspects: the development of drying technology combined with drying ventilation and warehouse drying technology, the development of energy conservation and biomass energy utilization technologies, and the development of intelligent control technologies.

Zhang Laiming said in a report titled “The Problems and Development Direction of China's Grain Drying” that although the level of comprehensive mechanization of agricultural production in China has been continuously improved, the level of mechanization for grain drying is very low, and it is less than 5%, and the mechanization level of Japan and the United States is widespread. above 95. In China's grain-drying industry, there are still problems such as low mechanization level, shortage of labor, large-sized dryers that are not suitable for use in the south, and food systems that cannot solve large quantities of wet grain drying. In the future, China's grain dryers should be large-scaled and miniaturized, fixed-type and mobile-type development, a variety of dry forms should be emphasized, agricultural machinery subsidy should be increased, and the grain drying problem in China should be solved according to local conditions. According to estimates, if the proportion of mechanical drying reaches 30%, at least 8000-10,000 sets of drying equipment are needed, and the market prospect of grain dryer in China is promising and the development potential is huge.

Wu Wenbin made it clear in the report titled "Technology and Development of Grain Processing Equipment at Home and Abroad," that China's grain processing equipment has reached the international advanced level. In the future, the development direction of China's grain processing equipment should be to improve the health of equipment; to develop new food machinery and equipment based on innovation; to strengthen basic theoretical research; to develop energy-saving processing equipment to achieve sustainable development; Manufacturing; innovative business ideas, providing better services and achieving a win-win situation.

Shen Jun pointed out in the report titled "The Direction and Practice for the Development of Wheat Milling Equipment Technology" that, as the country and the people are paying more attention to food safety, the development of wheat milling equipment to be safe and sanitary will be an inevitable trend. Processing companies require more and more stringent processing equipment. We need to research and develop more safe and sanitary equipment and processing technology. Equipment and engineering companies need to grasp the needs of the market and the people at all times to be invincible.

The reporter learned at the scene that due to the large space that grain drying equipment generally occupies, users are hampering the approval of land for plant construction and hope that the state can provide help and support in terms of policies. The dryer companies are facing pressure from the development of technology, policies and markets. The overall improvement of the industry and technological progress require the joint efforts of the government and supply and demand sides.

ANSI Threaded Flange

ASME B16.5 Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings. Included are:
(1) flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(2) flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(3) flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanged fittings with rating class designation 2500 in sizes NPS 1/2 through NPS 12 that are acknowledged in Non-Mandatory Appendix E in which only U.S. Customary units are provided.

B16.5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
This Standard is to be used in conjunction with equipment described in other volumes of the ASME B16 Series of Standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.

Careful application of these B16 Standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.

Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of valves with pressure equipment, plus all potential governing entities.
