Grain moisture meters: accuracy and control at every stage
Determination of grain moisture level is one of the key factors of successful storage and processing of agricultural products. The quality of the grain, its preservation, and even the market price depend on the exact measurement of humidity. Grain moisture meters help to quickly and accurately determine moisture, which makes them an indispensable tool for farmers and enterprises of the agro-industrial complex. In this article, we will consider how to choose a suitable hygrometer, its advantages and features of use.
1. Why is it necessary to measure grain moisture? Grain moisture plays a crucial role in its storage and processing. If the humidity level is too high, the grain can mold, sprout or rot. On the contrary, dry grain loses its qualities, may become brittle and unsuitable for processing. Therefore, it is important to control moisture at every stage - from harvesting to storage in silos or warehouses.
The main reasons why it is important to measure grain moisture:
- Preserving quality< /strong> : At the optimal level of moisture, the grain retains its nutritional properties and taste.
- Resource saving : Avoiding crop losses due to spoilage helps to save on re-harvesting and processing. >
- Accurate value assessment : Grain moisture affects its market value because buyers pay for commodity quality.
- Prevention of mold and mycotoxins : Correct measurement humidity helps prevent the development of mold and fungi that can spoil the grain.
2. How does a grain moisture meter work? Grain moisture meters are devices that measure the percentage of moisture in a grain sample. There are several types of moisture meters, each of which works according to different principles:
Electronic moisture meters : The most popular type of device that works on the basis of measuring the electrical conductivity of grain. Moisture in the grain changes its conductivity, and the moisture meter determines the moisture content based on these changes.
Infrared Moisture Meters : These devices use infrared radiation to determine moisture levels. in grain They are more accurate, but also more expensive.
Capacitive moisture meters : These devices measure the capacity of the grain, which varies depending on the moisture content. They are easy to use and relatively inexpensive.
Dielcometric moisture meters : These devices work by measuring the dielectric properties of grain, which depend on its moisture content. Such moisture meters provide accurate results, but require certain skills during use.
3. How to choose a moisture meter for grain? When choosing a moisture meter for grain, it is important to consider several factors so that the device meets your needs:
Measurement accuracy : One one of the key parameters is the accuracy of the device. The higher the accuracy, the better the device is suitable for professional use. Moisture meters with an accuracy of ±0.5-1% are suitable for small farms, while devices with an accuracy of up to 0.1% are needed for large enterprises.
Type of grain : Some moisture meters are only suitable for certain types of grain, such as wheat, corn, barley or soybeans. More universal models are able to measure the moisture content of various grain crops, which makes them more flexible in use.
Conditions of use : Moisture meters can be stationary or portable. Portable models are suitable for farmers who often take measurements directly in the field or in the warehouse, while stationary moisture meters are more convenient for large grain storage and processing plants.
Measurement time : It is important to take into account the speed at which the device performs measurements. Modern models can determine humidity in seconds, which saves time and allows you to make quick decisions.
Additional functions : Some moisture meters are equipped with memory functions, which allows you to save measurement results, as well as connect to computers for data analysis.
4. Advantages of using grain moisture meters Grain moisture meters have several key advantages that make them indispensable on the farm and in production facilities:
Quick measurement : Modern hygrometers can perform measurements in a few seconds, which allows you to quickly monitor humidity at various stages.
Ease of use : Most devices do not require complex setup and can be used without special knowledge.
Versatility Many models of moisture meters are suitable for measuring moisture in various crops - from wheat to corn and rape.
Accuracy High accuracy allows you to receive data with minimal error, which is especially important for large farms and processing companies.
- < p> Resource saving : Correct moisture measurement helps reduce grain losses and minimize drying and storage costs.
5. Recommendations for the use of grain moisture meters In order for the moisture meter to work efficiently and provide accurate results, it is important to follow a few simple rules:
Calibration of the device : Periodically check accuracy of the hygrometer and calibrate it according to the manufacturer's instructions. This will help to avoid measurement errors.
Sample selection : For accurate measurements, it is important to take grain samples from different areas of the field or storage. This will allow you to obtain average humidity data.
Instrument storage : Hygrometers should be stored in a dry place, away from moisture and dirt. This will extend the life of the device and ensure stable results.
Timely measurements : Do not delay the humidity measurement. It is especially important to check it before starting storage and after harvesting.
6. Frequently Asked Questions Q: Which type of moisture meter is best for corn?
Answer: Both electronic and infrared moisture meters are suitable for corn. Electronic models are more affordable and easier to use, while infrared ones give more accurate results.
Question: How often should a hygrometer be calibrated?
Answer: Calibration depends on the intensity of use of the device. On average, it is recommended to calibrate once every six months or after an intensive season.
Question: Can the moisture meter be used for different crops?
A: Yes, many models of moisture meters are universal and can to measure moisture content in various grain crops. However, check with the manufacturer for a list of supported crops before purchasing.
Conclusion Grain moisture meters are an important tool for any farmer or agribusiness. They help preserve product quality, minimize losses, and ensure proper grain storage conditions. When choosing a moisture meter, it is important to consider accuracy, type of grain being measured, conditions of use and additional functions. By following these recommendations, you will be able to choose the optimal device that will serve reliably for many seasons.
