Many scientific studies show that expander technology is an essential addition to a modern pelleting machine, as a useful tool to fulfill a wide range of customer needs in order to provide a different feed for every animal’s life stage.
The expander is installed right after the existing short-term conditioner and is suitable for any pellet mill brand. Conditioning of the feed takes place before the expander in the short-term conditioner with the addition of saturated steam and eventually liquids (molasses, fats), in order to ensure the success of the desired treatment.
The expander has been known in the oil milling industry for years and its use, combined with the pellet mill, begins in the 90s as a tool to sanitize the feed.
The expander can be integrated in any existing pelleting system without major supplementary space requirement or increasing specific energy consumption.
La Meccanica crumblers, with single or double roller, are used to produce crumbled feed pellet with a specific and controlled particle size and with a minimum of dust and can be adapted to meet specific customer needs.
When crumbling, careful attention must be given to the roll setting at both ends to keep the rolls parallel. The normal procedure is to set the roller gap and then catch the crumbles from each end of the rolls.
