Retention Time Barrel (RTB)
The Retention Time Barrel holds conditioned product at a controlled temperature for a set time to ensure uniform thermal treatment. A heated, insulated stainless steel barrel provides true first in first out flow, improving steam absorption, pellet durability, and often increasing capacity by up to 15%. It can be installed before a pellet mill, extruder, or meal cooler and is available in multiple sizes.
- Up to 15% higher pelleting capacity
- First-in/first-out product flow
- Constant temperature retention

FAQ
It holds the conditioned product at a stable temperature for a set period, improving heat transfer and pellet quality before pelleting or extrusion.
Pelleting capacity can increase by up to 15% due to higher temperature and improved steam absorption.
Through electric heating with rock-wool insulation and an adjustable thermostat (30–110°C).
All product-contact parts are made of stainless steel AISI 304 for hygiene and corrosion resistance.
Typically positioned after the conditioner and before the pellet mill, extruder, or meal cooler.
