Product Description

Spray drying is the technology most widely used in the liquid technology shaping and in the drying industry.The drying technology is most suitable for producing solid powder or particle products from liquid materials,such as:solution, emulsion, suspension and pumpable paste states,For this reason,when 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. 

After been filtered and heated the air enters into the air distrbutor on the top of the dryer.The hot air enters into the drying room in the spiral form and uniformly. 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.Throug the very short time of contacting the heat air,the materials can be dried into the final products.The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower. 

The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air flow,95%-98% of water can be evaporated at a moment.The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials. 
Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.

Features

1.Fine droplets are dried in the drying camber by supplying hot air through the inlet.
2.The surface of the liquid drop is dried immediately to form a tough shell.
3.Further the liquid inside must escape by diffusing through the shell at a particular rate.
4.At the same time heat transfer from outside to inside takes place at a rate greater than liquid diffusion rate.
5.As a result heat inside mounts up which allows the liquid to evaporates at faster rate.
6.This tendency of a liquid leadsto rise in the internal pressure which causes the droplets to swell.
7.The shells thickness decreases where as permeability for vapour increases.
8.If the shell is neither elastic nor permeable it ruputur and the internal pressure escapes.
9.The temperature of the air is adjusted in such a way that the droplets should be compeletly dried before reaching the walls of the drying chamber.
10.The products should not be over heated at the same time.

Application

1.Spray dryer can be used for drying of ny substances both in solution or in suspension.
2.Spray dryer are very useful for the drying of thermolabile substances.
3.Citric acid, borax, sodium phosphate, hexamine, gelatine and extracts are dried by a spray dryer.
4.The suspensions of starch, barium sulphate and calcium phosphate are also dried by the spray dryer.
5.Milk, soap and detergents too are dried by a spray dryer.
