Application of on-line densitometers in the dairy industry

In industrial equipment, the online liquid density meter is a good testing instrument that can measure the density of various liquids or liquid mixtures online.

The digital density meter works without process interruption and can be used directly for production process control. The top-mounted density meter for liquids has been widely used in various fields, such as sugar, brewing, dairy products, mining, oil refining, food processing, paper, chemical, petrochemical, pharmaceutical, and other industries. In the following, we discuss the application of online liquid densitometer in the dairy industry.

One of the key advantages of the liquid density meter is its ability to detect variations in milk composition. It is particularly crucial in the dairy industry, as even slight fluctuations in fat content can significantly impact the taste, texture, and overall quality of dairy products.

On the one hand, the chemical density meter needs to be placed in the "concentration" process of the dairy product to enhance the accuracy of the density measurement of highly concentrated milk, depending on the actual situation. However, after the production of the product, the instrumentation is cleaned with nitric acid, alkaline solutions, and water, so the equipment needs to be highly resistant to corrosion. On the other hand, in the non-contact milk powder density measurement, it is also necessary to improve the corrosion resistance and vibration resistance of the vibration tube of the liquid density meter 4-20mA, to enhance the performance of the pipe and the accuracy of the density measurement, so that the overall control system can operate normally.

In-line concentration meters monitor the concentration of whey protein, lactose, and fat in dairy products in real-time. By using specialized sensors and instruments, the concentration of these components in dairy products can be measured quickly and accurately. By monitoring concentrations in real time, producers can keep track of the quality of their products so that they can make the necessary adjustments and controls as needed. This helps maintain the quality stability of the dairy product and avoid the effects of concentration fluctuations on product performance.
