Spin Flash Dryer is used for an effective and efficient method of removal of surface or on bound moisture from a feed product. Spin Flash Dryers are designed for continuous drying of cohesive and non-cohesive pastes, filter cakes and high viscosity liquids. The wet cake appears granular and gets fluidized. Instantaneous exchange of heat and mass take place. The dried materials are taken in the collector as powder products.

Spin Flash Dryer is ideal for drying wet cake, slurry, and paste which is normally difficult to dry in other dryers. The material is fed by screw feeder through a variable speed drive into the vertical drying chamber where it is heated by hot air and at the same time disintegrated by a specially designed disintegrator. The heating of air may be direct or indirect depending upon the application. The dry powder is collected through cyclone separator / bag filter or with combination of both. It can be used to dry both organic and inorganic chemicals. Spin Flash Dryers are characterized by short residence time of a few seconds. Hence, great care needs to be taken in dispersion of the feed in the drying ...
... air, which is generally in the form of cake so that true surface water gets evaporated from the feed . Otherwise, the larger particles in the feed material may require longer drying time than the smaller ones in order to reach the desired moisture content.
Spin Flash Dryer provides:
Continuous process with short processing time for higher yield.
Complete temperature and speed control for optimum drying and minimum residence time.
Special feed agitator and screw conveyor to avoid bridge building.
Drying chamber with patented inverted conical base and rotor system for air velocity control, high drying efficiency and product protection.

Flash drying systems are designed based on feed and product characteristics, available or permissible heating source, and operational safety requirements. The drying gas is inert, and the solvent evaporated in the spin flash dryer is subsequently condensed. Such systems can be designed in a closed-cycle arrangement suitable for evaporation of organic solvents rather than water.
Special Features
Our 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.

State-of-the-art automation systems are available for the Spin Flash drying plants, enabling fully automatic control, process optimization, data logging, traceability, and maintenance scheduling.
Advantages
High drying efficiency providing low energy costs
Continuous processing with short processing time
Low operator overheads and minimum maintenance costs
Controlled residence time enabling high temperature drying
Controlled particle size
Very fine powder production eliminating requirement for milling
Limited space requirements
High-pressure, shock-resistant chamber for safe drying of flammable products

Best quality Spin Flash Dryer go for a simple design where there is a feed chamber, a drying chamber, and a bag filler.in the feed chamber the spin flash dryer manufacturers have an agitator to fragment the feed before drying. The spin flash dryer equipment is pushed into the drying chamber for which the spin flash dryer manufacturers may use a pump in case of liquids or any other device like the double shaft screw and the mono screw to push the feed.

In the Spin flash dryer process, chamber hot air is spin flash dryer supplied spin there is also a fan. SVAAR innovates with customers to help feed and enhance the world by designing, delivering and servicing high value solutions at the heart of growing and sustaining our diverse communities. We have successfully installed and commissioned several dryer plants across India and target to reach globally soon.
