Technology empowers grain storage. A 310,000-ton smart grain warehouse in Boli County, Qitaihe City is about to be put into use.

China News Service, Qitaihe, November 13 (Li Qiye, Liu Peng) Recently, the state-owned smart grain reserve project in Boli County, Qitaihe City, Heilongjiang Province was fully completed. This grain depot with intelligence as its core has a total storage capacity of 311,700 tons. After it is put into use, it will change the traditional grain storage model. Relying on automated management and control and full-process intelligent dispatch, the grain in the black soil can be "stored stably, managed accurately, and transferred quickly", and will build hardware support for regional food security.

The project covers a total area of ​​146,000 square meters, with a total construction area of ​​53,000 square meters, and a total investment of 429 million yuan. It is constructed by Boli County Hongsheng Grain Co., Ltd. with a construction period of two years. The project is located in an alpine area and went through two winter breaks during the construction period. The construction team overcame difficulties and faced challenges such as low-temperature construction in winter and multi-process cross-operation. At present, all physical civil works have been completed, and the reservoir area has the conditions for grain collection and storage operations.

Intelligence is the biggest feature of this grain depot. The entire process equipment automatic control system realizes remote control of grain reception, transportation, and warehouse scheduling. Staff can issue instructions in the central control room to accurately transport grain to the target warehouse, eliminating a lot of on-site manual operations. According to Lu Shiyao, project mechanical equipment manager, the automatic control system includes PLC cabinets, MCC cabinets and a central control platform. The large screen displays the operating status of the grain unloading station, working tower, elevator, shallow round silo feeder and various valves in real time. The entire process is visualized and dispatched to ensure intelligent grain warehousing.

The grain cleaning process also realizes automated closed operations, effectively reducing grain throwing losses. Project leader Wang Huaixiang said: "In the past, grain impurity removal relied on a single cleaning screen to operate independently. Now the cleaning screen and elevator operate in conjunction, impurities are removed simultaneously, and the entire process is closed and operated automatically to achieve precise grain feeding."

It is reported that the grain depot plans to be officially put into operation at the end of November. Ai Lijun, general manager of Boli County Hongsheng Grain Co., Ltd., said that after the grain depot is put into operation, it can undertake tasks such as policy grain reserve and rotation, commercial grain purchase, emergency grain transportation and supply guarantee, and at the same time provide post-production grain cleaning, drying, and warehousing services to surrounding farmers, reduce farmers' post-production grain loss, activate the local grain circulation market, and give full play to the role of the state-owned grain depot as a "ballast stone" in ensuring grain supply.
