The Continuous Seal Steam Tube Dryer offers tremendous advantages for solvent extraction or drying in an inert gas atmosphere.
- The STD unit`s revolutionary design permits material to be processed in a positive or negative pressure atmosphere and alleviates product and gas leakage into or out of the dryer.
- The dryer is operated as a counterflow unit. Air moves in the opposite direction of material flow.
- Sweep gas flow is used only to exhaust vapor and other gases created by the heating process, not to dry material.
- Low sweep gas velocity through the dryer vastly reduces the amount of product entrained in the exhaust stream.
- During solvent extraction, this not only means significant savings in the size and cost of recovery equipment, but simplifies dust collection requirements and reduces the cost of equipment required to handle the task.

MAIN DESIGN FEATURES
- STD provides higher thermal efficiency than any other type of dryer.
- Less flow of carrier gas compared with other types of dryers contributes to the reduction of material entrainment.
- Drying temperature can easily be adjusted by controlling steam pressure, thereby providing favorable conditions for heat-sensitive materials.
- STD is capable of processing larger capacity of material continuously.
- Compact gas sealing construction minimizes gas leakage from the dryer.
- Stable operation, high thermal efficiency, less flow of carrier gas and easy maintenance lead to low operation cost.
- High thermal efficiency with minimal heat loss
- Indirect heat and low temperature drying suited for a wide variety of materials
- Uniform mixing and drying ensures extremely high product quality
- Simple operation, startup, and shutdown
- Low operating and maintenance costs
- Available in wide range of sizes to meet application requirements
