The Cracker/Stuffer machine breaks the wet grain and stuffed into a silo bag of high density, resulting in a pre-digested food with high quality and digestible energy value almost up to 96%, which is achieved through the grain fragmentation and moisture which it is exposed to fermentation by a correct grinding and compacting. The low power consumption required for the operation of this system makes an important ally of the livestock by providing a minimum operating cost with high performance per hour.
