Spin Flash dryers are designed for continuous drying of cohesive and non-cohesive pastes and filter cakes, as well as high-viscosity liquids. The main components in a Spin Flash plant are a feed system, the patented drying chamber and a bag filter.


The spin flash dryer provides a short continuous operation process to achieve higher performance. You have full control of temperature and speed for optimal drying. It has a drying chamber with a patented inverted conical base and a rotation system to control air speed, high drying efficiency and product protection. They are simple to operate and dismantle for cleaning.


Feed system
The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying. A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber.

Drying chamber

The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow.

Bag filter

Powder from the drying chamber is collected in bag filter, while the outlet airleaves the system at the top via a suction fan.

Special features

Anhydro's patented Spin Flash plant features an inverted cone for high velocity air inlet at the base of the drying chambers preventing risk of product built-up. This unique technique has proven to be the customer-preferred method of drying paste in the industrial sector.
