Is it thick, sticky or heat-sensitive?
Some liquids are thick or sticky; others change when heated. These differences affect whether this dryer is suitable.
Agitated Thin Film Dryer
Agitated thin film drying.
Manage concentrated waste.
An agitated thin film dryer (ATFD) removes moisture from concentrated liquid. Moving blades spread a thin layer across a heated wall. Water leaves as vapour and drier material is collected, with both outputs handled as part of the treatment plan.
See how it works
Inside the dryer
A thin layer makes the difference.
Inside the dryer, a turning shaft with blades keeps spreading and moving the material against the hot wall. Heat turns moisture into vapour. The movement helps expose more of the material to the drying surface.
- In: concentrated liquid
- Liquid with much of its water already removed enters here.
- Inside: a thin moving layer
- Turning blades spread the liquid over the hot wall.
- Out: water vapour + drier solids
- The two leave through separate routes.
The bigger picture
Less water. Waste still needs care.
Taking water out can make the leftover waste easier to collect. Drying does not remove every harmful substance or turn the waste into something we can automatically sell.
Dried material
Test what is left, then choose a suitable way to store it and dispose of it or recover useful material.
Vapour
The water vapour leaves separately. Equipment cools it back into liquid, with extra treatment where needed.
Before the dryer
An evaporator can remove some water first. This leaves less liquid for the dryer to handle.

Will this material dry well?
What should come out?
Decide how dry the material needs to be and how it will be collected. Not every liquid becomes a loose powder.
Safe operation
Choose equipment that can handle the material and heat. Leave room for cleaning and repairs, and plan where the vapour goes.
Let’s talk about cost
What will you be paying for?
A dryer needs energy to remove moisture. Its cost covers the machine, the heat to dry the material and the work needed to look after what comes out.
Buying and setting it up
You pay for the dryer, its rotating parts, heating equipment and controls. Equipment to collect vapour and dried material, plus installation, needs to be included in the agreed scope.
The bills after installation
Budget for heat, electricity, cleaning and maintenance. The dried material still needs storage and a suitable destination, which can add handling and disposal costs.
Why prices can differ
A wetter or stickier feed can behave very differently in a dryer. How much material you process, how dry it must become and how it affects the equipment all influence the cost.
