Overview
A thin film, dried in seconds
The HG drum scraper dryer is rotating continuous drying equipment with internal heat conduction. A film of material adheres to the drum from the trough under it. Heat passes through the drum wall into the film and evaporates the moisture.
The dried product is scraped off by a blade on the drum surface and falls to the screw conveyor under the blade, which carries it away to be collected and packed.
Coat
The rotating drum picks up a film of material from the trough below it.
Dry
Heat passes through the drum wall into the film and evaporates the moisture.
Scrape
A blade removes the dried product, and a screw conveyor carries it away.

Features
Efficient heat, flexible operation
Feed concentration, film thickness, medium temperature and drum speed can each be adjusted.
- 01
High thermal efficiency
Heat moves by conduction in one direction, so apart from cover loss and radiation the heat evaporates the film. Thermal efficiency reaches 70 to 80%.
- 02
Flexible
The feed concentration, film thickness, heating medium temperature and drum speed can be adjusted, and they do not depend on each other.
- 03
Short drying time
The drying cycle is generally only 10 to 300 seconds, which suits heat-sensitive material. The dryer can also run under vacuum.
- 04
High drying rate
The film is thin, generally 0.3 to 1.5 mm, so the surface keeps evaporating 20 to 70 kg H₂O per m² per hour.
- 05
Continuous output
Dried product drops onto a screw conveyor and is collected and packed.
- 06
Nine sizes
Roller sizes from Φ600×800 mm to Φ1800×2000 mm.

Questions
Before you order
01How does the drum scraper dryer work?
A rotating drum picks up a film of material from a trough. Heat passes through the drum wall and dries the film. A blade scrapes the dried product onto a screw conveyor.
02How long does the material take to dry?
The drying cycle is generally only 10 to 300 seconds.
03Is it suitable for heat-sensitive material?
Yes. The short drying time suits heat-sensitive material, and the dryer can also run under vacuum.
04What can I adjust?
The feed concentration, the film thickness, the heating medium temperature and the drum speed.
05How efficient is it?
Thermal efficiency is up to 70 to 80%, because heat is conducted straight into the material film.
