SWDP Series Feed Pellet Stabilizer — Higher PDI, Less Stress Cracking
SWDP series feed pellet stabilizer is installed after the cooler to give hot pellets extra retention time at controlled temperature. The stabilizer relieves internal stress, improves starch gelatinization and helps increase PDI while reducing fines and moisture migration.
Why SWDP Feed Pellet Stabilizer
Post-conditioning stabilizes pellets after cooling, improving durability and storage behavior.
Extra retention time at elevated temperature helps increase PDI and reduce fines.
Controlled bed height and multiple stages keep pellets inside for the required time.
Slow-moving conveying and proper guiding avoid additional pellet damage.
Single or multi-stage design fits different line capacities and PDI targets.
Installed between cooler discharge and screener / crumbler / bins in most layouts.
Access doors and smooth internal surfaces support inspection and cleaning.
