Milk Electric Pressure Centrifugal Spray Dryer Design

20.Cocurrent Flow Pressure Spray Granulation Dryer

Product Description

pressure spray dryer is suitable for solution, suspension, slurry, paste material, etc. Liquid material is atomized to small fog drops. And fog drops contact with hot air directly in the drying tower. Moisture content is evaporated instantly. So spray dryer features high efficiency, high mass transfer area, and short drying time, in general it is 5~30 seconds. Operating temperature can be adjusted according to actual situation, in general inlet air temperature is 150~500°C. And its automation control degree is control, environment solution environment can be solved.

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.
