According to the Regulations on Crop Seed Inspection, the four quality indicators of seed purity, clarity, germination rate and moisture are the necessary items for seed inspection. The quality indicators are implemented by national mandatory standards, and any batch of seeds. If the indicator does not meet the standards set by the state, it will be judged as a substandard seed. The moisture content of seeds directly affects the transportation of seeds, safe storage and the life of seeds.
At present, there are various kinds of electronic moisture measuring instruments on the market, which are mainly divided into three categories: capacitive, resistive and microwave. They are fast and convenient, but the test results of quite a few fast moisture meters are not accurate enough and reproducible. Poor. In particular, the plug-in type of rapid moisture meter is very different, and the results of vertical insertion, oblique insertion, flat insertion, and insertion speed are different. In addition, there are pressure bar and clamp type quick-measuring moisture meter, which often show different measurement results due to the different sizes of each person's hand. There are many methods for measuring the moisture content in seeds. The pyrolysis method is preferred because it is simple, fast, accurate, and has a small amount of samples. Therefore, it is getting more and more widely used. The pyrolysis method includes a national standard drying method, an infrared fast moisture analyzer, and a halogen rapid moisture meter.
Working principle: The seed moisture analyzer is designed by the principle of pyrolysis weight and is a new type of rapid food industry moisture detection instrument. The seed moisture meter measures the weight of the sample, and the infrared heating unit and the moisture evaporation channel quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the moisture content lost by the sample, and the final measured moisture after the drying process is completed. The content value is displayed as a lock. Compared with the international oven heating method, infrared heating can reach the maximum heating power in the shortest time. The sample is fast and dry at high temperature. The detection result is in good agreement with the national standard oven method, and it has substitutability and high detection efficiency. In the oven method. The general sample can be measured in just a few minutes.
Application: Seed moisture analyzer can be widely used in all food industry laboratories and production processes that need to quickly measure moisture. It can also be used in laboratories and production processes in medicine, food, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemicals, tea, food, meat and textiles, agriculture, forestry, paper, rubber, plastics, textiles, etc. .
Product features: Seed moisture analyzer, can reach the maximum heating power in the shortest time, easy to operate, accurate test, the display part uses red digital tube, the indication value is clearly visible, respectively, can display the moisture value, the initial value of the sample, the final value, Measuring time, temperature initial value, final value and other data, and has the function of connecting with computer and printer. The average product can be tested in 3-5 minutes. 1, small size, light weight 2, fast detection speed, accurate 3, simple operation, accurate test 4, display part using red digital tube display 5, wide range of uses 6, with computer, printer connection function

Human adenovirus has 51 serotypes, 6 subgroups A-F, and the genome is a linear double-stranded DNA molecule. Groups B, C, and E are associated with respiratory infections; groups A and F are associated with gastrointestinal infections, groups D and E are associated with eye infection; and groups D and E are associated with kidney and urinary tract infections. Adenovirus is acid-resistant, so it can continue to remain active through the gastrointestinal tract.
