SBDP Spray Bag Dryer

The SBDP series is a completely new type of spray dryer that replaces the drying chamber with a filter bag. The drying and granulation process are all finished in this filter bag for higher product quality and able to produce a variety of products with different raw materials.

The drying chamber of traditional spray dryers are made of stainless and cyclone(s) are also necessary. By contrast, the spray bag dryers use a filter bag for drying chamber which are easy to attach and detach so that all powder products are collected under the bottom of the bag. It is especially suitable for drying and granulating those fine ceramics and chemical products that don’t need size grading.

  Higher recovery rate and no separation of multi-components due to only 1-point collection.

4) Space-saving installation

  Compact devices that do not require cyclone or bag filters.

5) Easy raw material switching

Use several filter bags as dedicated drying chambers so that raw materials can be switched quickly.

6) Less energy loss

As the thermal capacitance of the drying chamber (filter bags) is small, chamber can be heated to specified temperature in a short time, while the heat loss during operation is also less.

7) Various atomizers available

Not limited to rotary disc for feed atomizing: Two-fluid nozzle and air-assisted two-fluid nozzle are also available.
