Currently, the production of feed in micro pellet format has increased due to its nutritional benefits and the added value it brings to the production chain. However, this diet requires a high inclusion of ingredients that are sensitive to temperature and humidity, such as sugars and dairy products. Many producers wonder: what is the best way to pelletize this diet?

The exposure of these ingredients to temperature, humidity, and processing time must be carefully controlled; otherwise, the modification of the primary structures of the ingredients could cause difficulties in pellet formation and production interruptions.

Our partner ANDRITZ Feed & Biofuel specializes in micro pellet pelleting, with several installed designs and proven customer satisfaction. With a line design specific to this solution, the thermal treatment step begins with ANDRITZ conditioners featuring adjustable paddles and rotation. Steam is then added through a multi-point system, which evenly mixes the steam with the feed.
To ensure the entire system works in harmony, we include our pellet line control and automation system, which provides all the commands and parameter settings the customer needs. Finally, specific adjustments are made to the pellet mill to maximize electricity savings and guarantee continuous, interruption-free production.

Another important factor is the die configuration. If the holes are too small, the pressure force on the surface can endanger the die itself, so it is essential to define the pellet diameter (Ø) and compression ratio specifically for each case, depending on its application.
