IKA Conical Dryer CD

The IKA Conical Dryer CD is suited for vacuum contact drying of various humid solids of different free flowing behavior as well as different bulk densities. Not only the conical dryer’s vessel wall and vessel cover are heatable but also the special spiral agitator. This ensures an optimal energy input into the product and also a uniform humidity and temperature distribution in the entire product area.

Your bulk material is effectively dried at temperatures up to 200°C and under vacuum. The resulting solvent vapors are extracted by a reversible flow dust filter. The speed of the spiral agitator, which is located in an overhung position in the cover, is infinitely adjustable.

The conical dryer CD has a combined tilting and slewing mechanism. For cleaning and inspection purposes, the tilting device offers convenient opening of the entire vessel cover including the agitator. Alternatively, this mechanism allows for the entire vessel to be inclined when the cover is closed. This has an extremely positive effect on the drying process. The inclination offers important advantages in mixing, as gravitation additionally affects the products to be dried. The slewing drive enables the entire vessel to be held between 0° and 45° at any position.

The conical dryer can optionally be equipped with a CIP mechanism, sampling and/or load cells. On request, IKA will also deliver optional peripheral devices for the conical dryer, such as solid filling or packing systems, a heating/cooling aggregate, a vacuum system with solvent condensation, and a fully automatic control.

IKA conical dryers are available in sizes ranging from 10 to 10.000 liters useful volume.

Advantages of the IKA Conical Dryer:

Shorter drying times due to a heatable agitator and double-jacketed heatable vessel
Vessel operation under vacuum and pressure up to 6 bar
Admissible operating temperatures from -10 to +200°C
A flow breaker with an integrated temperature sensor PT 100 prevents the medium from rotating with the agitator
Overhung-mounted lump breaker for disintegration of agglomerates
Gentle mixing of sensitive products with special spiral agitator
Better mixing result by slewing of the entire mixing vessel
Configuration of agitator and vessel wall prevents product accumulation on heat transfer surfaces
Exposed shaft without product-touching bearings
Various shaft seal systems available for all applications
The stirrer speed can be infinitely adapted to meet product characteristics
Safe tilting mechanism to open the vessel lid for easy access to the vessel / stirrer
Complete emptying of the vessel via a spherical segment valve
Vapor filter eliminates dust from the exhaust
Complete system easy to clean – integrated spray nozzles cover the entire inner surface
Easy to access because of equipment height
Many equipment options available through one source
The Conical Dryer CD is available as explosion-proof and GMP versions
Reliable scale-up
Various sampling systems; suitable for a wide range of requirements

Typical applications for the IKA Conical Dryer CD are:

Vacuum drying of metal powders, other powders, pigments, salts, crystals, or fine chemicals under permanent mixing
Suspension separation and thermal drying
Production of tea mixtures, coffee powder products, powdered soups and sauces and baby food
Separation of active ingredients and solvents for the production of pharmaceuticals
