Food is the material basis for human survival, and the quality of food is a major matter related to the national economy and people's livelihood. From May 25 to 30, 2023, Henan encountered 5 days of rain during the ripening period of wheat, and some areas ushered in the worst "rotten rain" in the past decade, that is, the wheat harvest encountered continuous rainy days, causing the wheat to ripen, but could not be harvested in time, and even the wheat that had been harvested, many of them were blackened, germinated, and even moldy due to excessive humidity. "What happened to Henan wheat?" It has always touched the hearts of many Chinese people.
Industry analyst Li Wenxu said that the rain in the wheat harvest season will make the unripe wheat grain grout insufficient, affecting the yield and quality, and after the mature wheat germinates, it cannot be used as high-quality wheat to supply flour mills, but can be used as raw materials for feed and winemaking production.
The statements of some growers more directly reflect the impact of the "rotten rain" in Henan. Villagers in Xiangzishu Village, Yingzhuang Town, Wolong District, Henan Province, said that all their wheat has sprouted, which has not reached the national purchase standard, and can only be sold as feed. According to the output of 1000 jin per mu, it means that the loss per mu reaches 500 yuan.
Henan is an important grain property right in the mainland, and it is the largest wheat-producing area, accounting for a quarter of the country's output. The priority is to do everything in your power to grab the harvest.
In addition to rush harvesting, drying and warehousing also need to follow. In the case of "rotten rain" rush harvest, the water content of the harvested wheat is more than 30%, and the water content is still 20% after drying, which is still a considerable gap from the storage standard below 13%. Therefore, it is necessary to dry the wheat again, and closely monitor the moisture change data of the grain in real time after storage, effectively ensure the implementation of the grain loss reduction work of rushing to harvest summer grain In the process of grain storage, temperature, humidity, moisture are the most important factors affecting the quality of food, and are the quality standards strictly controlled by the domestic and foreign food departments. The moisture in the grain should neither be too high nor too low. Too much water will promote the vigorous activity of food life, causing food fever, mildew, insects and other biochemical reactions, resulting in food deterioration. Too low moisture will destroy organic matter, reduce food quality, and reduce weight. According to statistics, the annual loss caused by insufficient moisture monitoring in the mainland reaches about 1% of the total output, equivalent to a loss of more than 4 billion yuan.
In the face of sudden natural disasters, reduce the subsequent food loss, the degree of loss to the minimum is our attention and concern issues, Zhongke Galaxy core as a domestic focus on the field of temperature and humidity sensor industry experts, the use of the company's own technical advantages and product characteristics for the current summer grain safe storage to do its best, for the disaster grain area of the grain silo we can provide free of charge of grain silo temperature and humidity measurement technical support and temperature and humidity product trial, for the smart grain silo accurate temperature and humidity data monitoring help.
Beijing Zhongke Galaxy Core independent research and development design of temperature, humidity, moisture sensor chip in the field of accurate protection of grain monitoring can be said to escort for many years, the intelligent grain silo system perception layer is covered with a variety of sensors, can collect real-time grain temperature, humidity, moisture, oxygen, nitrogen, insect and other data information, and through the Internet technology display in the cloud, we can observe the data information of these grains on mobile phones, computers, central control screens.
Accurate data to help us make correct judgment and accurate control, the use of comprehensive control equipment (ventilation, temperature control, refrigeration, fumigation, etc.), high temperature, low temperature, quasi-low temperature set different levels of grain storage temperature conditions, food in the storage process of different temperature, humidity, moisture changes, data will automatically monitor and allocate processing, equipment will also automatically carry out zonal temperature adjustment debugging, ventilation and refrigeration and other measures to ensure that the food will not deteriorate, no manual intervention is required, basic data collection is the premise of accurate control.
The innovative ideas of multi-layer multi-point collection (sensors), intelligent mechanical control, and multi-dimensional data computing of the whole chain of information are used as the basis for building a smart grain warehouse, which is in line with the real-time data monitoring function of the current green grain warehouse. Today, we have upgraded the need for innovation in cryogenic grain storage, which maintains the quality and nutritional value of food by reducing the temperature and humidity inside the grain silo and inhibiting microbial activity and oxidation in the grain. The system regulates the temperature and humidity inside the grain silo through the automatic refrigeration equipment and air conditioning system, keeping it within a suitable range, and can also automatically monitor and control the temperature and humidity, so that the temperature and moisture of the grain are within the optimal range to ensure the stability of the grain quality and the taste advantage. The new intelligent sensor technology provides accurate, reliable, scientific and intelligent temperature, humidity and water data information collection solutions for grain warehouses, and at the same time carries efficient, low-cost, green ecological intelligent control solutions to promote the substantial transformation of green grain warehouses.
As we all know, with the innovation and upgrading of the grain monitoring module under the evolution of digital information, Zhongke Galaxy Core has many years of practical experience in the field of grain monitoring, and in the perception sensor acquisition module, we have gradually upgraded from the initial real-time temperature monitoring to temperature and humidity monitoring, moisture monitoring, gas monitoring, insect mold detection, anti-fumigation and other systematic sensor solutions that meet green storage.
