Product Description

High Speed Ceramic Spray Dryer Nano Instant Coffee Honey Dryer spray Egg Powder Lab Scale Spray Dryer

Spray drying is the most wide applied process in liquid process shaping and drying industry.The drying technology is most suitable for producing solid powder or practical products from liquid material,such as :solution,emulsion,suspension and pumpable paste states.For this reason,the particle size and distribution of the final products,residual water contents,mass density and the particle shape must meet the precise standard,spray drying is one of the most desired technologies.

Main Principle:

After air gets filtered and heated,it enters into an air distributor on the top of the dryer.The hot air enters into the drying room in a uniformly spiral form.Passing through the high speed centrifugal sprayer on the top of the tower,the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Through a very short time of contacting the hot air,materials get dried.The final products discharge continuously from the bottom of the drying tower and from the cyclones.The waste gas will be discharged from blower.
 

Feature:

1.With the 3-stage purifying device, the air meets the 100000-grade standard.

2.There are cooling devices for the reactor, the temperature of the container wall is less than 80ºC, and even the raw products are stayed on the wall, will not be burned.
3.With the flushing device, the machine can be applied for the drying for many kinds of products.
4.The wet-type dust collecting is adopted, which meets the environment protecting standard.
5.There is the air cleaning device.
6.In the atomizer, the variable-frequency speed regulating is equipped.
7.There is the touch screen and the PLC.
8.CIP

Working principle: Spray drying is a method of producing a dry powder from a liquid or slurry 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 rotary disc atomizer by mono pump and atomized into fine droplets inside the drying chamber. Heated and filtered hot air will be blown into the air distributor at the same time. The evenly and swirly distributed hot air completely contacts with the droplets for heat transfer. In several seconds, the droplets will be dried into powder and sucked out into the cyclone for discharging via exhaust fan.

 

Application: LPG series spray dryer has been widely used in pharmaceutical, chemical and foodstuff industry for drying liquid material into fine powder.


Technical advantages of spray dryer :

1)  Particle size control: The dry particle size can be easily controlled by atomization of the liquid feed and the design of the hot gas inlet. This spray dryer can typically produce between 30 to 500 micron average particle size, in a bell shaped distribution.
 
2)  The evaporative cooling of product: The heat and mass transfer during drying occurs in the air and vapor films surrounding the droplet. This protective envelope of vapor keeps the particle at the saturation temperature. As long as the particle does not become "bone-dry", evaporation is still taking place and the temperature of the solids will not approach the dryer outlet temperature.
 
3) Short residence time: The surface area produced by atomization of the liquid feed enables a short gas residence time, ranging from 3-10 seconds depending upon the application, which permits spray drying without thermal degradation.
 
4) Flow properties of dry product: The shape of most spray dried particles is spherical, which provides for fluid-like flow properties.  This makes many downstream operations, such as packaging, pressing, filtering, and handling easier and less costly.
 
5) Size design of drying chamber: The size of drying chamber is specially designed to prevent droplets sticking to the inner wall, dried powder accumulating on the cone part and guarantee enough residence time.
