5kg/H - 30000kg/H Continuous Vacuum LPG High Speed Centrifugal Spray Dryer with Spray Atomizer
The drying technology is most suitable for producing the powder, particle products from the materials, such as: Solution, emulsion, soliquoid and pumpable paste states.
For this reason, when the particle size and distribution of the final products, their residual water contents, the stacking density and the particle shape must meet the precision standard, the spray drying is one of the most desired technologies.
Working Principle
Spray drying is a method of producing dry powder from liquid or slurry materials by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals.
Liquid material is pumped into the top installed centrifugal disc atomizer by mono pump and atomized into fine droplets inside the drying chamber. Meanwhile, clean hot air is blown into the air distributor at the same time. The evenly and swirly distributed hot air completely contacts with droplets for heat transfer. The droplets are dried into powder in several seconds and sucked out into the cyclone for discharging via exhaust fan.
LPG series spray dryer has been widely used in pharmaceutical, chemical and foodstuff industry for drying liquid material into fine powder.
Main Features
(1) Fast drying: liquid or wet raw material after atomization, significantly increased surface area, in the hot air flow, instantaneous evaporation can be 95% ~98% moisture, to complete the drying time only a few seconds, and especially suitable for drying of thermal sensitive material.
(2) Excellent drying effect: Finished products with good uniformity, fluidity and solubility, the product high purity, good quality.
(3) Production process is simple, convenient operation and control. For material which moisture content 40-60% (special material even moisture contents 90%) of the liquid to a dry powder products, dried without crushing and screening, and product purity. Product size, density and moisture can be adjusted( within a certain range) by changing the operating conditions.
