20.Cocurrent Flow Pressure Spray Granulation Dryer
Product Description
Description
The liquid or paste raw material is sprayed into mini liquid drops
by pressed atomizer which draws assistance from pressure or
diaphragm pump, and quickly drying through heat exchange. (10-90
sec) at last, the powder or small granule is finished.
Features
1. Drying speed is fast and suitable for drying thermal sensitivity
material particularly.
2. The finished product is ball granule with uniform size. Its
fluidity and solubility are good. The purity of product is high and
its quality is good.
3. It applied scope is wide. According to the characteristics of
raw material, it can use hot air to dry and can also use cool air
to granulate. It has strong adaptability to raw materials.
4. Its operation is simple and stable; its control is simple and
convenient, easy to realize automatic operation.
Note:
1 The amount of evaporated water is related to characteristic of
raw material and temperature of evaporation. The parameters in
table is calculated as 150-160°C
2 Customer could choose different drying way such as: current
steam, countercurrent steam and powder returning drying to meet the
requirement of product.
3 The flow chart sketch is just for show, customer could pick
subassembly according to need.
Applications
pressure liquid dryer is applicable in foodstuff, pharmaceutical,
chemical industries, dyestuff, ceramics, biochemical, plastic
industries and so on.
YT series automatic high-efficiency, energy-saving and
environmentally friendly cocurrent flow pressure spray granulation
drying equipment is to input materials such as solution,
suspension, emulsion, paste and paste through a high-pressure pump
high-pressure input nozzle, spray mist droplets, and rise like a
fountain. , and then the solid and water are separated and dried by
heat exchange with hot air to obtain granular products. According
to the process requirements, the pressure of the liquid pump and
the size of the flow orifice can be adjusted to obtain the required
spherical particles according to the size ratio, and can also
obtain larger diameter particles.
Scope of Application
YT series co-current pressure spray granulation dryer has been used
in electronic ceramics, precision ceramics, architectural ceramics,
magnetic materials, new energy materials, metal materials,
pharmaceuticals, biology, food, fine chemicals and other industries
that have special particle requirements for materials. For pressure
spray granulation, the particle size distribution requirements can
be adjusted to an excellent distribution curve value, and its main
technical performance and indicators can reach a relatively
advanced level, realizing the automatic control of the overall
equipment, energy saving and environmental protection.
Main Features
1. Fast drying speed;
2. The obtained product is spherical or apple-shaped spherical
particles with uniform particle size, good fluidity and solubility.
The product has higher purity and better quality;
3. Wide range of use, hot air drying, granulation, cold air
granulation, spray crystallization, spray reaction, etc.
4. The operation is simple and convenient, the control is stable,
and it is easy to realize automatic operation. The particle size,
bulk density and water content of the product can be adjusted
within a certain range.
5. According to different materials, the pressure spraying method
of co-current (spraying from top to bottom) or counter-current
(spraying from bottom to top) can be used.
