The agriculture industry pesticides Spin Flash Dryer DESCRIPTION

In the flash dryer, particles are dispersed by different means - depending on the product - into a hot air stream at high velocity conveying and drying the product to a free flowing powder in a very short time. The short residence time allows for high temperatures of the inlet drying air due to the cooling effect provided by the fast evaporation of the moisture from the particle surfaces. Spin Flash Dryers is used for drying technology of high-viscosity products, pastes and filter cakes widely acclaimed by customers In a variety of industries all over world, if the wet cake is a paste or sludge, swirl flash dryer is the most suited for drying application. The dryer is fitted with a mechanical agitator which helps to disperse the wet cake without any need for back mixing of the dry powder. this process provides a faster and more energy-efficient alternative to spray drying. With quite a few spin flash dryer installations in the world, XINYU combines experience and cutting-edge technology into added-value solutions for our customers.

The agriculture industry pesticides Spin Flash Dryer CHARACTERISTICS

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. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.

The agriculture industry pesticides Spin Flash Dryer ADVANTAGES

• High drying efficiency and low energy costs
• Direct drying with no initial diluting
• Continuous processing with short drying time
• Low operator overheads and minimum maintenance costs

The agriculture industry pesticides Spin Flash Dryer APPLICATION

Flash dryers have been used to dry products in many industries including food, chemical, mineral and polymer. A broad range of feed materials including powders, cakes, granules, flakes, pastes, gels, and slurries can be processed. For slurries, pastes, or sticky materials, back mixing of the wet feed with a portion of dry product to produce a suitable conditioned material is required. This technology can also be used for cooling applications.
• Agrochemicals
• Ceramics
• Food and feed products
• Inorganic chemicals
• Organic chemicals
• Pharmaceuticals
• Pigments and dyestuffs

The agriculture industry pesticides Spin Flash Dryer TECHNICAL PARAMETERS

The drying economy is very dependant upon the source of energy and the maximum allowable inlet temperatures (often up to 225 °C depending on the heat sensitivity of the product). If a wanted low residual moisture is not obtained easily in the simple flash dryer special designs can be considered or further drying can take place. This could be a second flash dryer or more often a fluid bed where longer residence time at lower and safer temperatures is possible and unwanted over-drying can be avoided.
