Laboratory Spray Dryer S Series

Specifications of Laboratory Spray Dryer S Series

1. Centrifugal atomizer:

The specially designed centrifugal atomizer is suitable for producing particles from 10μm to 150μm. The particle size can be adjusted by the design of the atomizer disc and the rotation speed. Compared with other spray modes, the centrifugal atomizer will generate powders with narrower particle size distribution(a high peak) and more free fluidity.

2. One-fluid nozzle:

The one-fluid nozzle mode uses liquid pressure to generate kinetic energy. When the pressure increases, the liquid flow rate increases, and the size of the spray droplets will decrease accordingly. According to the different liquid properties and operating conditions, we provide a series of nozzle apertures for your choice.

3. Two-fluid nozzle:

The two-fluid nozzle is recommended when making powders less than 20μm. The two-fluid nozzle consists of two channels, the liquid, and compressed air. The high-speed airflow generated from the compressed air channel instantly atomizes the products from the liquid channel into fine particles and forms powder in particle sizes to ten microns or even single microns after drying, meeting customers' requirements for particles extremely small.

The dry powder obtained by the atomization using a two-fluid nozzle has uniform particles with good fluidity, and its original characteristics remain. This type of atomization is easy to operate and maintain due to its simple structure. In addition, for liquids with high concentration and viscosity, our independently developed nozzles are available to prevent clogging.
