Before and after the grain purchase, storage, production and processing need to monitor its moisture, temperature and quality. The application of the grain moisture analyzer can effectively avoid the detection of grain moisture. The level depends on the eyes, the hand touch, the mouth bite and other senses. The arbitrariness of the decision, the accuracy of the test, and the strict control of grain moisture changes are very important for safe storage of food!
China is a big agricultural country. The quality and safety of food is a major event that affects the national economy and the people's livelihood. In addition, food is affected by natural disasters, market price fluctuations and other factors. To ensure the stability of grain production, we must also pay attention to the quality and safety of grain reserves. As we all know, Drying is an important condition for ensuring food security reserves. Because dry food is easy to store, it is not easy to be worms and moldy, it can slow down the aging effect and reduce losses, thus ensuring the nutrition and quality of food, while wet food is easy to insects and mold. , deterioration, agglomeration, affecting food safety.
The author understands that humidity is an indispensable parameter for many products in the environment. Of course, the storage environment of grain also needs to consider the humidity factor. The general rule is that the higher the water content of grain, the more susceptible the grain is to heat and mildew, and the more serious the pest damage. Relatively speaking, in the environment with low humidity, although the activities of insects and cockroaches cannot be completely avoided, there will be some worms that cannot adapt to dry conditions and whose physiological balance is destroyed and cannot survive. At the same time, some will also be due to ' Water shortage', reproductive capacity will decline.
To this end, the grain should be kept as low as possible before storage. The food safety storage needs a suitable moisture, called safe moisture. The upper limit of safe moisture, called critical moisture, the grain storage with higher moisture content than the critical moisture, its quality It is difficult to ensure safety. It can be seen that it is essential to detect the moisture and moisture of food. The moisture detection of grain can be measured by scientific instruments, which can avoid the inaccuracy of grain moisture content caused by traditional methods such as hand grasping and tooth biting. Happening.
At present, there are various moisture analyzers in the market, such as infrared moisture analyzer, dew point moisture analyzer, microwave moisture analyzer, coulometer moisture analyzer and grain moisture analyzer, etc., and grain moisture analyzer as a professional moisture detection instrument in the grain market. The role of the drug is more and more prominent. It is mainly used for the moisture detection of cereals, beans, coarse grains, rice and other food crops. It can also satisfy the solids, granules, powders, gels and solids produced in grain production and processing. Determination of liquid moisture content.
According to relevant personnel, the grain moisture analyzer only needs to sample and check the parts that are easy to absorb moisture, condensation or abnormal temperature rise of the grain. It does not need to weigh, can automatically measure the weight of the sample, and automatically calculate the moisture content ratio. Compared with the manual measurement of moisture, it is not necessary to consider the accuracy, repeatability, reproducibility, ease of operation, time required for measurement, cost required for analysis, etc., convenient, fast and accurate.
In addition, the author understands that the new grain moisture meter has been improved on traditional testing instruments, on the one hand, the feeding funnel has been improved, making it more automated, user-friendly, reducing operational errors, and greatly improving measurement accuracy. The aspect has improved the internal structure, eliminated the external environmental impact, and made the instrument's environment adaptability stronger, thus improving the measurement accuracy. It also measured the increase of grain varieties, and can detect more than ten varieties, basically covering most common food crops.
It is reported that the rapid measurement instrument for grain moisture introduced by a certain enterprise in Shanghai adopts the touch screen automatic detection system, which can automatically monitor the moisture and temperature inside the grain in real time, and has the advantages of accuracy, intuition, reliability, etc. In addition, it has automatic disconnection function. After the measurement is completed, the power will be automatically disconnected within 30 seconds, which not only saves electricity, but also reduces the safety hazard caused by the user's forgetting operation. At present, such instruments are subject to grain and oil purchase, grain storage and other departments, or seed companies and The favor of other departments.
In summary, China's grain output is considerable, and most of the grain enters the circulation and storage. In the grain storage process, due to the long storage period, the grain is prone to heat and mildew, so it is necessary to prepare the water, temperature, and mold of the grain. The detection can better ensure the quality and safety of the stored grain. The grain moisture analyzer can overcome the shortcomings of the traditional detection, and has the advantages of simple and convenient operation, fast detection, high precision, non-destructive testing, low detection cost, etc. The food market has been widely used.
