The Ring Dryer is a special development of the Flash Dryer Incorporating an internal airborne recycle For greatly improved operation and efficiency. Our designed of Ring Drying System consists of a “manifold” or “internal classification which differentiate it from flash dryer The Internal ‘circulation in the Ring Dryer, which is of the manifold, a special centrifugal classifier designed to separate dry and fine particles While holding large moist particles in prolonged circulation this enables the Ring Dryer to process many materials that were earlier considered difficult to dried with the help of a Flash Dryer efficiently and also to obtain exceptionally good control of the final product moisture content. The effect of the manifold together with a disintegrator in the drying duct, can give a combination of drying without screen grinding, with the manifold releasing fine and dried material only from the dryer, whilst returning coarse internal to the disintegrator for further drying and grinding.

Applicable Industries and Products
Applications:
DDGS drying in Distilleries with Thick Syrup
Description:
DDGS Ring Dryer is defined like a flash dryer as the drying of particles that are suspended and conveyed in a hot air stream. The main difference between DDGS ring dryer and a flash dryer system which is used for drying in industry is presence of DDGS classifier in Ring dryer. The principle of Ring Dryer is also to evaporate surface moisture instantaneously. It is well known fact that the surface area of wet lump increases as the size of lump decreases. The wet cake is disintegrated into fines to increase the surface area.
Ring Dryers incorporate a centrifugal classifier giving selective internal recirculation of semi-dried solids effectively lengthening the retention time of larger particles in the dryer while finer material, which dries more rapidly, exits the dryer with the exhaust air.
The classifier uses the centrifugal forces created through passing a product containing airstream around a curve to concentrate the product into a moving layer. The adjustable splitter blades are used to cut this layer and return the heavier, semi-dried material back to the dryer for another pass through the system while the lighter, drier product exits the dryer and gets conveyed to the product collection system. Manifolds can have single or multi classification blades and are often used in combination with disintegrators for greater control of particle size, product moisture and exhaust temperature.
Starch Industries – Maize Gluten, maize Protein
Maize Gluten Ring Dryer is defined like a starch flash dryer as the drying of particles that are suspended and conveyed in a hot air stream. The main difference between Maize Gluten ring dryer and a flash dryer system which is used for starch drying in starch industry is presence of gluten classifier in Ring dryer. The principle of Ring Dryer is also to evaporate surface moisture instantaneously. It is well known fact that the surface area of wet lump increases as the size of lump decreases. The wet cake is disintegrated into fines to increase the surface area.

Food Industries – Tomato Powder, Lemon Powder Etc.
Ring Dryer has been used to dry products in many industries including food, chemical, mineral and plastics. A broad range of feed materials including powders, cakes, granules, flakes, pastes, gels, and slurries can be processed. For slurries, pastes, or sticky materials, our specifically designed feed system allows back-mixing of the wet feed with a portion of dry product to produce a suitable conditioned material for feeding into the dryer. Special extrusion systems are also used for viscous products such Tomato powder Egg Powder Lemon Powder Etc.
