XFSFY-50A Corn Flour Moisture Meter

Why Control the Moisture Content of Cornmeal

Corn is a traditional bulk agricultural product in China, with its production, consumption, and export volume holding a significant share internationally. During the production and storage of corn, improper production methods and environmental conditions can lead to contamination and proliferation of mold in corn. Among these factors, the moisture content of corn, as well as the integrity and maturity of corn kernels, greatly influence the risk of mold development. Particularly for processed products like cornmeal and cornstarch, if the moisture content is too high, severe mold growth can occur during processing, storage, and transportation, affecting product quality and causing losses for corn purchasing and processing enterprises. It may also pose direct and potential risks to human health. Additionally, corn is a major raw material in the feed and livestock industries. Mold caused by excessive moisture in corn raw materials and processed products can also impact animal husbandry. Therefore, controlling the moisture content of corn kernels and cornmeal during production and processing is crucial.

How to Detect and Control the Moisture Content of Cornmeal

The traditional method for detecting the moisture content of cornmeal involves using a national standard oven at 130 degrees Celsius to heat and dry the sample for four hours. The weight difference before and after heating represents the moisture content, and the percentage of this difference relative to the initial weight is the moisture rate. With the rapid development of industrial production, the traditional oven method can no longer meet the growing demands of enterprises. As a result, new halogen rapid moisture analyzers have emerged. These devices also apply the drying principle of ovens but use high-power ring halogen lamps for heating, enabling quick and uniform drying of samples without damaging their surfaces. They offer high measurement accuracy and excellent testing results, with the added advantage of very fast detection times—typically completing moisture content tests in just over ten minutes. These analyzers are widely used in modern corn processing plants. After measuring the moisture rate of cornmeal samples, the results are compared with national standard quality indicators, and appropriate adjustments to moisture content are made accordingly.

National Standard for Cornmeal Moisture Content

According to the national standard GB1353-2009 for corn quality indicators, the moisture content of corn must not exceed 14%.

How to Use a Cornmeal Moisture Analyzer

Using a halogen moisture analyzer to test the moisture content of cornstarch is very simple and convenient. First, when the instrument displays 0.000, take 3-5g of cornstarch and spread it evenly in the sample pan. Close the heating chamber cover and press the start button to begin heating and drying. At the end of the test, the instrument automatically displays the moisture rate as a percentage.

Price of Moisture Analyzers for Grains like Cornmeal

The price of moisture analyzers for testing the moisture content of grains such as cornmeal, flour, rice flour, starch, soybeans, wheat, and peanuts generally varies based on accuracy, with higher precision models being more expensive. The economy model XFSFY-60A costs 1800 yuan, the standard model is priced at 2500 yuan, and the high-precision rapid moisture analyzer XFSFY-120B is priced at 3600 yuan. High-precision moisture analyzers are typically used for quality testing of cotton and grains where accurate moisture content detection is critical.

Application Range of Cornmeal Moisture Analyzers

The application range of halogen moisture analyzers for cornmeal is very broad, covering almost any industry that requires moisture content detection. For example, they can be used for testing moisture in grains like corn, wheat, peanuts, soybeans, barley, sorghum, and rice, as well as various foods, dried seafood, medicinal herbs, dried tangerine peel, ingredients, nuts, walnut kernels, sunflower seeds, pecans, dried longan, dried longan pulp, almonds, raisins, dried cranberries, and more. They are also suitable for monitoring moisture content in meat products such as identifying water-injected pork, beef jerky, sausages, cured meat, pork jerky, beef dices, and surimi. By reasonably controlling product moisture content, these devices help ensure the safety of storage, transportation, and preservation.
