The soft curtain quick cold storage door has a simple design and is designed with a heating antifreeze device to ensure smooth and efficient operation of the product in a low temperature working environment. The structure incorporates the function design of collision avoidance recovery. When the door body is accidentally impacted, it deviates from the track and automatically repairs the return position during the ascent process. This structure not only facilitates the safe and smooth operation of the door body, but also operates more than 150,000 times a year without failure. It extends the life of the product while reducing component replacement and maintenance costs.
Such rapid door is specially designed for freezer, cold room, or cool room. It is made from 30 mm thick thermal insulated,sandwich curtain, and with all-round heating device to avoid frozen. Thus it can work well in low temperature like -25 º C. It can reduce thermal transmission by fast opening and closing, and thermal insulated door curtain. For each door, it can help customer save energy cost by at least USD 8000 every year,than traditional normal speed cold room sliding doors.

The first is to speed up the application of new-type corn sowing machinery, and the level of mechanized operations has been further improved. This year, the new maize planting machinery will be used as the key for agricultural machinery subsidy. The province has added nearly 10,000 new corn seeding machines of various types, and new machines such as corn fine seeder and no-tillage planter have been widely used in the province. The new corn planting machinery is "Summer" played the role of fighting for farm time, increasing benefits, and standardizing seeding standards. The province's mechanized sowing of corn has reached more than 39 million mu and the machine sowing rate has reached 93%.
The second is to vigorously implement "one-stop" mechanization operations and grab corn before sowing. The agricultural machinery departments at all levels in the province took effective measures to organize agricultural machinery cooperatives and large agricultural machinery manufacturers to speed up the popularization of the “one-stop†mechanized operation model of “wheat harvesting, straw smashing and field replanting, and corn no-tillage plantingâ€. More than 20,000 were established. A "one-stop" team has implemented "one-stop" mechanization operations throughout the province, so that wheat will follow the harvest and corn will be broadcast, shortening the operation time, saving corn seeds and ensuring the quality of sowing. Corn planting 7-10 days in advance, grabbed the province before the arrival of the rainy season.
The third is to implement standardized corn planting operations, which laid the foundation for the harvest of autumn crops. Agricultural machinery departments at all levels paid attention to the combination of agricultural machinery and agronomy. According to the combination of machinery and arts, they issued technical advice on mechanized sowing of corn to the whole province, formulated a standard of sowing distance of 60 cm for corn machinery, and vigorously promoted corn and other row spacing and no-tillage sowing techniques in the province. Through mechanized sowing of maize, the province basically unified the row spacing of corn and achieved standardized planting, which laid the foundation for mechanized harvesting of autumn corn and created conditions for the regaining of corn.
In this year's “Three Summersâ€, the Shandong Provincial Department of Agricultural Machinery fully promoted new types of corn sowing machinery, such as precision seeding machines and no-tillage seeders, and vigorously promoted “wheat harvesting, straw smashing, and no-tillage sowingâ€.†The one-stop "mechanized operation mode" speeds up the progress of corn planting and improves the quality of sowing. The mechanism of corn planting is closely followed by the harvesting of wheat, the harvesting of machinery, and the end of machine broadcasting, laying the foundation for the harvest of autumn corn.
