Checking Moisture Content in Powdered Milk

Precise quality control in powdered milk includes measuring the moisture content in order to make processing line changes as needed. Obtaining a low moisture content can control chemical reactions in skim milk powder that is being stored at room temperatures, to not effect the nutritive value of the powder, even with years of storage. 

MoistTech has countless years of experience and installations around the world that has built the knowledge behind our technology. Improving the manufacturers quality control process, product and plant efficiency are just some of the many benefits that can be immediately seen with proper moisture measurement and control.

With dairy powders, the average range of moisture content is between 3- 4% and the primary way for drying the powder is through spray drying. Spray drying, in its simplest form, consists of atomizing the feed, spray-air contact, drying, and separation of the dried product from the drying air. MoistTech’s moisture analyzers are unaffected by any changes in height or color in material and has the ability to ignore any gaps on the product line.

Milk powder can absorb moisture from the immediate environment under ambient conditions, making the monitoring and measuring of moisture content extremely important. Most commonly in dairy powder applications the moisture is measured after the spray drying process and/or just prior to the packaging process.
