Characteristics and application of experimental spray dryer

The experimental spray dryer is compact and movable, and the machine is self-contained and can be used without powering up the auxiliary facilities. It adopts PLC control, touch screen display, and Chinese and English operation interface. Main components and electrical appliances imports. The whole machine is compact in design and can be moved. The machine is self-contained and can be used without powering up the auxiliary facilities. It adopts PLC control, touch screen display, and Chinese and English operation interface.

Characteristics and application of experimental spray dryer :

1. The drying speed is fast. After the spray of the liquid, the specific surface area is greatly increased. In the high-temperature airflow, 95~98% of the water can be evaporated instantaneously.

Drying time takes only a few seconds.

2. The co-current spray drying method can make the droplets flow in the same direction as the hot air. Although the hot air temperature is high, the hot air enters the drying chamber and immediately contacts the spray droplets. The indoor temperature drops rapidly and the dry material is not heated too much. Suitable for drying heat sensitive materials.

3. Wide range of use. Depending on the characteristics of the material, it can be dried by hot air or cold air. A large number of products with different characteristics can be used for this production. Commonly used are: polymers and resins, dyes, pigments, ceramics, glass, rust removal. Agents, insecticides, carbohydrates, dairy products, tannins, by-products of slaughterhouses, blood and blood products, detergents and surfactants, fertilizers, organic compounds, inorganic compounds, instant foods, pharmaceuticals, etc. .

4. Since the drying process is completed in an instant, the particles of the product substantially maintain the spherical shape of the droplets, and have good dispersibility, fluidity and solubility.

5. The production process is simplified and easy to operate and control. Spray drying is usually used for solutions with a moisture content of 40 to 60%. Even if the content of special materials is as high as 90%, it can be dried into a powdered product at one time. After drying, most products do not need to be pulverized and screened, which reduces the production process and simplifies. The production process has improved the purity of the product. For the particle size, bulk density, and moisture of the product, the operating conditions can be changed within a certain range to adjust and control.

6. In order to prevent the materials from being polluted and prolong the life of the equipment, all parts in contact with the materials are made of stainless steel. For ease of operation, the control system uses an integrated operation.
