Higher quality and more valuable feed with Moisture Control

Knowing and controlling the moisture content of your materials from the introduction of the raw materials to the packaging of the final product is key to maximising efficiency, optimising yield and producing a high-quality, consistent product

The perfect solution is to constantly measure the flowing materials’ moisture content and correct moisture variations in real-time. The use of online moisture measurement sensors enables the control system to automatically react to changes and adjust the process to achieve a continuous and precise moisture level in the material, whether for storage, further processing, or final packaging.

Why should you measure moisture?

1. Raw materials vary in moisture content, and this variation leads to weighing discrepancies.
2. Accurate control of the moisture during the drying process prevents under-drying and over-drying.

Where should you measure moisture?

Moisture control throughout the process allows the production of higher quality, balanced and more valuable feed:

• Drying for Storage at the outlet of a dryer
• Milling / Tempering at the inlet of the tempering system
• Pelleting / Conditioning during the conditioning process
• Drying for packaging at the outlet of a dryer

Online vs offline moisture measurement?

Measuring online in real-time offers significant benefits over offline measurements. Periodic offline sampling is time-consuming and subject to:

• Equipment measurement errors
• Process errors
• Sampling errors

Installing and integrating an online sensor to measure the moisture continuously gives a much better method for monitoring the material flow. 

Benefits

By controlling the moisture during the weighing up of the raw materials, it is possible to correctly control the protein content of the final pellet and guarantee superior product quality. There are also cost benefits of water control ranging from an increase in the yield from a raw material, a reduction in spoiled material and optimisation of the energy input into the processes.

Conclusion

Using a consistent blend of usable materials and maintaining a constant final moisture target saves energy and extends the time between dryer maintenance. Benefits also include producing a consistent feed with a repeatable and homogenous nutritional value and a reliable shelf life.

The Hydronix XT range of sensors use an industry-leading Digital Microwave Measurement Technique and have a proven track record in these types of applications throughout the world. In addition, the sensors are simple to install and require very little maintenance.
