KJG-Vacuum Paddle Dryer

Vacuum Conduction Dryer with Hollow Paddle Agitator

The Vacuum Paddle Dryer stands out with its large heating surface and wedge-shaped hollow paddle agitators, outperforming conventional rake vacuum dryers in heating effectiveness. It moves and heats materials while operating under vacuum at low temperatures, making it suitable for handling flammable, explosive, organic-solvent-based and heat-sensitive materials.

Input: Liquids, Slurries, Pastes, Mashes
Output: Powder with 3%–10% moisture content
Temperature: Heat source temperature range of 50°C to 200°C
Additional Feature: Mixing, Mild Crushing

A Vacuum Paddle Dryer with Hollow Wedge Agitators

SINOTHERMO's vacuum paddle dryer — a hollow paddle, indirect-heat conduction dryer — dries liquids, slurries, pastes and mashes into powder using heated, wedge-shaped hollow paddles that both agitate and heat the material under vacuum. The heated paddles add conduction surface beyond a rake dryer, so drying is faster and more efficient for flammable, solvent-wet and heat-sensitive products.

Wedge-shaped hollow paddles carry heating medium inside, adding conduction surface on top of the jacket so materials heat and dry faster than in a conventional rake vacuum dryer.
The rotating paddles constantly mix and turn the batch, renewing the heated surface, preventing crusting and giving uniform drying to 3–10% moisture.
Vacuum lowers the evaporation point so drying runs at a 50–200°C heat source, protecting heat-sensitive products and enabling organic-solvent recovery.
The sealed, low-oxygen vacuum shell safely dries flammable, explosive and solvent-laden materials that cannot be dried in open air.
The wedge paddle profile provides mild crushing and a self-wiping action that limits buildup and delivers free-flowing powder.
