Grain is the material foundation for human survival, and the quality of grain is a major issue related to the national economy and people's livelihood. From May 25th to 30th, 2023, Henan Province was experiencing a 5-day rainfall during the wheat ripening period. Some areas experienced the most severe "rotten field rain" in the past decade, which was continuous cloudy and rainy days during the wheat harvest, causing the wheat to mature but unable to be harvested in a timely manner. Even the wheat that had already been harvested was often blackened, germinated, and even moldy due to high humidity. How is Henan wheat doing? "Has always touched the hearts of many Chinese people.

Li Wenxu, an industry analyst, said that rain in the wheat harvest season would make the immature wheat grains insufficiently filled, affecting the yield and quality. After germination, mature wheat could not be used as high-quality wheat for Gristmill, but could be used as feed and raw materials for wine production.

Some growers' statements directly reflect the public impact of the "rotten rain" in Henan. Villagers in Xiangzishu Village, Yingzhuang Town, Wolong District, Henan Province, said that all their wheat sprouted, which could not meet the national purchase standards, and could only be sold as feed. Calculated based on a yield of 1000 catties per acre, it means a loss of 500 yuan per acre.

The Central Plains is ripe, and the world is abundant. Henan is an important grain property right in China, and it is also the largest wheat producing area, accounting for a quarter of the country's output. The top priority is to make every effort to seize it.

In addition to rush collection, drying and warehousing also need to follow closely. In the situation of "rotten field rain" rush harvest, the moisture content of the harvested wheat is above 30%, and after drying once, the moisture content is still at 20%, which is still a considerable gap from the storage standard of less than 13%. Therefore, it is necessary to re dry the wheat and closely monitor the moisture change data of the grain in real time after storage, effectively ensuring the implementation of grain protection and loss reduction in the rush to harvest summer grain. During the grain storage process, temperature, humidity, and moisture are the most important factors affecting grain quality, and are the quality standards strictly controlled by domestic and foreign grain departments. The moisture content in grain should neither be too high nor too low. Excessive moisture can promote the vigorous activity of food, causing food to heat, mold, infest insects, and other biochemical reactions, leading to food spoilage. Low moisture can damage organic matter, reduce grain quality, and reduce weight. According to statistics, the annual loss caused by insufficient water monitoring in China accounts for about 1% of the total production, equivalent to over 4 billion yuan in RMB.

In the face of sudden natural disasters, reducing subsequent grain loss and minimizing the degree of loss are issues that we attach great importance to and pay attention to. As an industry expert specializing in the field of temperature and humidity sensor segmentation in China, Zhongke Yinhe Xin can use its own technological advantages and product characteristics to contribute to the current safe storage of summer grain, We can provide free technical support for temperature and humidity measurement in grain warehouses located in disaster stricken areas, as well as trial use of temperature and humidity products, to assist in accurate temperature and humidity data monitoring of smart grain warehouses.

The temperature, humidity, and moisture sensor chips independently developed and designed by Beijing Zhongke Yinhe Xin have been providing protection in the field of precise monitoring of grain conditions for many years. The smart grain warehouse system is filled with various sensors in the perception layer, which can collect real-time data information on temperature, humidity, moisture, oxygen, nitrogen, insect pest, and other aspects of grain. They are displayed in the cloud through internet technology. We use mobile phones, computers The central control screen can observe various data information of these grains.

Accurate data helps us make correct judgments and control accurately. By using comprehensive control equipment (such as ventilation, temperature control, refrigeration, fumigation, etc.), different levels of storage temperature conditions are set for high, low, and quasi low temperatures. When different temperature, humidity, and moisture changes occur during the storage process, the data will be automatically monitored and adjusted, and the equipment will also automatically perform temperature adjustment and debugging in different zones, Ventilation and cooling measures ensure that food does not deteriorate and do not require manual intervention. Basic data collection is a prerequisite for precise control.

Innovative thinking such as full chain, multi-layer, multi-point collection of information (sensors), intelligent mechanical control, and multi-dimensional data calculation serve as the foundation for building a smart grain depot, which is in line with the real-time data monitoring function of the current green grain depot. Nowadays, we have upgraded the innovative demand for low-temperature grain storage by reducing the temperature and humidity inside the grain warehouse, inhibiting microbial activity and oxidation in the grain, thereby maintaining the quality and nutritional value of the grain. The system adjusts the temperature and humidity inside the granary through automated refrigeration equipment and air conditioning system, maintaining them within a suitable range. At the same time, it can also automatically monitor and control the temperature and humidity, keeping the temperature and moisture of the grain within the optimal range, ensuring the stability of grain quality and taste advantages. The new intelligent sensor technology provides precise, reliable, scientific, and intelligent temperature, humidity, and water data information collection solutions for grain depots, while also carrying efficient, low-cost, and green ecological intelligent control solutions to promote substantive transformation of green grain depots.

As is well known, with the innovation and upgrading of the grain monitoring module under the evolution of digital information, Zhongke Yinhe Xin has many years of practical experience in the field of grain monitoring. In the perception sensor collection module, we have gradually upgraded from the initial real-time temperature monitoring to temperature and humidity monitoring, moisture monitoring, gas monitoring, pest and mold detection, anti fumigation, and other systematic sensor solutions that comply with green warehousing.
