Drying mechanization in Jiangxi Province is promising

Posted on

Jiangxi is a large agricultural province. The province has a vast area of ​​grain production. Each year, due to rainy weather or poor weather during harvest, grain mold is particularly variable. The Chengxin Farm on the Poyang Lake Plain is deeply touched. In October, the annual harvest season is often rainy and rainy. The harvested rice sprouts and deteriorates because it is not dried in time. The crops planted in one year suffer a lot of losses. In 1999, it tried to introduce a low-temperature circulating dryer from Shanghai Sanjiu Machinery Co., Ltd., and passed the two-month drying test, which fully met the requirements. It has introduced three long-term low-temperature dryers to the following brigade for use three times, resulting in good economic and social benefits. At present, the whole farm has purchased 15 dryers, which has solved the problem of dining on the sky. Zhuhai Farm, which is not far from Chengxin Farm, saw the economic benefits of using driers from fraternal units in 2000. It also purchased three long-term low-temperature dryers at one time.

At present, Chengxin Farm and Zhugang Farm are the most concentrated and longest-used dryers in our province. To this end, the leaders of the Jiangxi Provincial Agricultural Machinery Bureau have repeatedly visited and researched to lay the foundation for better implementation of the Ministry of Agriculture's grain production area drying project. From the research situation, more users of the dryer still stayed in the disaster-resistance and security, and only used the dryer when the weather was not good. In some developed coastal provinces, dryers have become very popular. They have been harvested from rice and immediately entered the dryers for fresh drying operations. The shipment of rice to small packages does not fall through the entire production process. In fact, because rice does not land, fresh, nutritious, and healthy, this “living” rice that will “breathe” will have better market competitiveness and can sell at a good price. The peasants will have even greater income.

The steps are repeated until the investment reaches its required thickness-usually 5 to 15 mm (0.2 to 0.6 in). Investment moulds are left to dry completely, which can take 16 to 48 hours. Drying can be accelerated by applying a vacuum or minimizing environmental humidity. Investment moulds can also be created by placing the pattern clusters into a flask and then pouring liquid investment material from above. The flask is then vibrated to allow entrapped air to escape and help the investment material fill any small voids. Common refractory materials used to create the investments are: silica, zircon, various aluminium silicates, and alumina.Burnout preheating: The mold is then subjected to a burnout, which heats the mold to between 870 °C and 1095 °C to remove any moisture and residual wax, and to sinter the mold. Sometimes this heating is also used to preheat the mould before pouring, but other times the mould is allowed to cool so that it can be tested. Preheating allows the metal to stay liquid longer so that it can better fill all mould details and increase dimensional accuracy. If the mold is left to cool, any cracks found can be repaired with ceramic slurry or special cements
