What should I do if the moisture content of corn starch exceeds the standard? How to choose the right moisture analyzer?
The importance of corn moisture detection
Corn is in the north of China's main production area. The weather is cold when harvested. In addition, the bracts at the ears of the corn are not sufficiently dried in the sun, so the original moisture of corn is generally high. The moisture of newly harvested corn is generally 15-20% in North China and 20-30% in Northeast and Inner Mongolia. The maturity of corn is often not very uniform, because the pollination time of the top and base of the same ear is different, resulting in insufficient maturity of the top grain. Corn with uneven maturity is not conducive to safe storage. The grain depot should be divided into different warehouses with different moisture content. When entering the warehouse, corn should be stored separately according to different water content and different grades. Lay a preliminary foundation for safe storage. Corn with high moisture content should be dried before entering the warehouse. In addition, the price of corn with different moisture content is also different during the acquisition process. For the benefit of the majority of grain farmers and purchasers, testing corn moisture content is an indispensable item. At present, there are a variety of electronic moisture detectors on the market, which are mainly divided into three categories: capacitive, resistive and infrared drying methods, which are fast and convenient. Poor availability. Especially for the plug-in type fast moisture meter, vertical insertion, oblique insertion, horizontal insertion, and insertion speed have different results. In addition, there are pressure bar and clamp-type quick moisture meter, which often shows different measurement results due to the different strength of each person's hand. Infrared drying method has the advantages of simplicity, speed, accuracy, and small sample volume, and is the first choice. Therefore, it is more and more widely used. The infrared drying method includes an infrared rapid moisture analyzer and a halogen rapid moisture analyzer.
Application field
The corn starch moisture meter can be widely used in laboratories and production processes in all industries that require rapid moisture determination, such as food, aquatic products, grain, corn, cereals, starch, cassava, flour, noodles, agriculture, forestry, and tea.
working principle
The corn starch moisture meter is also called halogen rapid moisture analyzer. The instrument is designed based on the principle of pyrolysis weight and is a new type of rapid moisture detection instrument in the food industry. While measuring the weight of the sample, the moisture analyzer uses the ring tube halogen heating method to quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the moisture content% of the sample. After the drying process is completed, the final measured moisture The content value is locked and displayed. Compared with the international oven heating method, halogen heating can evenly and quickly dry the sample at high temperature, and the sample surface is not easy to be damaged. The test results have good consistency with the national standard oven method, are replaceable, and the detection efficiency is far higher For the oven method. General samples can be measured in just a few minutes.
