With the progress of society, instruments are also being updated daily. Agricultural instruments are constantly changing. In recent years, some high-tech instruments have also become more and more commonly used by agricultural workers. For example, the soil nutrient analyzer mainly tests available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, soil pH, and soil salinity in soil, plants, chemical fertilizers, and biological fertilizers. There are several ways to use the soil nutrient analyzer, such as: laboratory chemical analysis method, traditional rapid measurement method (reagent method) and so on. Now we have developed a new method that uses the spectroscopy test - near-infrared soil nutrient analyzer. It is different from the application of traditional soil nutrient speed meter. Let me make some simple analysis below.
First, function:
Near-infrared soil analyzer function: It can measure the content of N, P, K, organic matter, water, etc. in the soil. If other parameters are needed, it can be input into the model.
Traditional soil nutrient quick-measuring instrument function: Measurable available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content in soil, plant, chemical fertilizer, biological fertilizer, etc., soil pH, soil salt content the amount.
Second, the operation method:
Near-infrared soil analyzer: Applying spectral technology, combined with data mining and fusion technology, a rapid test analysis method for soil nutrients was proposed, realizing rapid real-time testing of soil nutrients. Without destroying the sample and without the need for chemical reagents, soil samples can be directly measured by placing soil samples in the sample chamber.
Traditional soil nutrient fastness tester: using the reagent method, the sample needs to be pre-treated, the steps are complicated, and there must be no leakage of the reagent in a step-by-step manner. The staff must be careful when requesting it.
Third, the test results time:
Near Infrared Soil Analyzer: Because it uses spectrometry, it takes only 1 minute.
Traditional soil nutrient tester: Including pretreatment time 40 minutes to 1 hour.
Fourth, late-stage costs:
Near-infrared soil analyzer: There is no cost other than electricity and no reagents are required.
Traditional soil nutrient speed tester: Reagent cost, between 1.2 yuan and 2 yuan per sample.
Fifth, scalability
Near-infrared soil analyzer: can change the model or increase the model to test more parameters, superior scalability.
Traditional soil nutrient tester: can only measure NPK, PH, EC nutrient, no expansion function.
In conclusion, the near-infrared soil analyzer has: applied spectrum technology, combined with data mining and fusion technology, proposed a rapid soil nutrient testing analysis method, and achieved real-time rapid testing of soil nutrients. The test results are fast and the cost is zero. And with scalable performance. Of course, the price of the instrument is also much higher than that of the traditional soil nutrient tester, but according to long-term considerations, it can be regarded as a suitable instrument for various scientific research units and researchers. Because it saves time, saves money, saves energy, and expands performance.
The continuous development of the era of near-infrared soil analyzers will generally enter agricultural research units and have been widely used. We also hope that high-tech, high-efficiency instruments can be used more widely. So that the country's scientific and technological water products can be higher and higher.

Drying equipment is a crucial component in many industries, including food processing, pharmaceuticals, and chemical manufacturing. These machines are designed to remove moisture from materials and products, which can help to increase their shelf life, improve their quality, and reduce their weight.
There are many different types of drying equipment available on the market today, each with its own unique set of features and benefits. Some of the most common types include air dryers, rotary dryers, fluidized bed dryers, and freeze dryers.
Air dryers are the simplest and most affordable type of drying equipment. They work by blowing hot air over the surface of the material or product being dried, which causes the moisture to evaporate. Rotary dryers are similar to air dryers, but they use a rotating drum to agitate the material and improve the drying process.
Fluidized bed dryers are a more advanced type of drying equipment that use a bed of hot air to suspend and dry the material being processed. This allows for faster and more efficient drying, as well as improved product quality.
Freeze dryers are a specialized type of drying equipment that are used primarily in the pharmaceutical industry. They work by freezing the material being dried and then removing the moisture through a process called sublimation.
Regardless of the type of drying equipment used, it is important to choose a machine that is well-suited to the specific needs of your industry and application. Factors to consider when selecting a drying machine include the type and volume of material being processed, the required level of moisture removal, and the available space and resources for installation and operation.
Overall, drying equipment is an essential tool for many industries, and can help to improve product quality, reduce waste, and increase efficiency. With so many different types of machines available on the market today, it is important to carefully evaluate your options and choose a machine that will meet your specific needs and requirements.
