The importance of detecting moisture in cornâ€
Corn is in the north of the main producing areas of China. The weather is cold at the time of harvesting, and the leaves of the corn ear are not fully sun-dried on the plants, so the original moisture of the corn is generally higher. The newly harvested corn moisture is generally 15-20% in North China and 20-30% in Northeast China and Inner Mongolia. The maturity of corn is often not very uniform, because the top of the same ear has different pollination time from the base, resulting in insufficient top seed maturity. Corn with uneven maturity is not conducive to safe storage. The grain depot should be divided into different waters. When corn is put into storage, it should be stored separately according to the water content and grade. Lay the initial foundation for safe storage. Corn with high moisture content should be dried before storage. In addition, corn with different moisture content is not the same in the process of acquisition. For the benefit of the majority of food farmers and purchasers, testing the moisture content of corn is an essential item. At present, there are various kinds of electronic moisture measuring instruments on the market, which are mainly divided into three categories: capacitive, resistive and infrared drying. It is fast and convenient, but the test results of quite a few fast moisture meters are not accurate enough. Poor current. 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. The infrared drying 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 infrared drying method includes an infrared rapid moisture meter and a halogen rapid moisture meter.
Application field
Corn starch moisture meter can be widely used in all industries that need to quickly measure moisture, such as food, aquatic products, grain, corn, grain, starch, cassava, flour, noodles, agriculture, forestry, tea and other industries in the laboratory and production process.
working principle
Corn starch moisture meter is also called halogen rapid moisture analyzer. The instrument is designed by the principle of pyrolysis weight. It is a new type of rapid food industry moisture detection instrument. While measuring the weight of the sample, the instrument uses a circular tube halogen heating method to quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the % moisture content lost by the sample. After the drying process is completed, the final measured moisture is obtained. The content value is displayed as a lock. Compared with the international oven heating method, halogen heating can dry the sample evenly and quickly at high temperature, the surface of the sample is not easily damaged, and the detection result has good consistency with the national standard oven method, and has the alternative, and the detection efficiency is far high. In the oven method. The general sample can be measured in just a few minutes.
