    • Fluid Bed Dryer

    Fluid or Fluidized bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content in raw ingredients like powder and granules.

    The working principle of this equipment includes fluidization of the fed materials. In this process, hot air at a high temperature and pressure is introduced in the system through a perforated bed of moist solid particulate.

    Overview

    Fluid bed dryers, as their name suggests, are used for drying materials such as granules, tablets, powders, fertilizers, and plastics. They are particularly popular in production industries like:

    • Chemical
    • Pharmaceutical
    • Food
    • Dairy
    • Metallurgical
    • Dyes
    • Other process industries

     Fluid or Fluidized bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content in raw ingredients like powder and granules.

    The working principle of this equipment includes fluidization of the fed materials. In this process, hot air at a high temperature and pressure is introduced in the system through a perforated bed of moist solid particulate.

    The solids are lifted from the bottom that are slightly wet in condition and are suspended in a stream of air (fluidized state). Heat transfer occurs as soon as there is a direct contact between the wet solid and hot gases.

    The dry gas takes away the vaporized liquid. The gas exiting is partially recycled, sometimes.

    Fluid Bed Dryer is composed of a stainless steel chamber having a detachable bottom, which is often perforated and this is called the bowl. Through this perforated bottom, the air is introduced and with the help of heaters that increases the temperature of the air present inside. The heated air is then filtered and is allowed to pass through the bed of the material. Within the system, there is a provision for an attachment of a fan. The fan initiates and monitors the air flow direction. One can also regulate the air flow and the temperature at which the machine is working.

    The Fluid Bed Dryer bag expands with the flow of air and powder particles start a turbulent motion. The material gets dry inside due to perpetual exposure to dry air. The material thus exiting the system is once again filtered.

    Materials, after they are dried in a constant-rate drying, are processed via wet-bulb temperature. This process ensures that the ingredients dried through this process to low moisture content, under relatively low temperatures. One can achieve high drying results by installing the heat exchanging tubes or panels, which cover 80% of the heat exchange process. Due to the presence of a large heat exchange area inside the Fluidised Bed Dryer, the required gas amount is small. To check this issue, the sizes of each equipment of the system used in the system is minimized.

    Some of the main benefits of using fluid bed dryers are as follows:

    1. These dryers have high thermal efficiency as compared to the tray dryers.
    2. These dryers come in varying sizes with drying capacity from 5 to 500 kg per hour.
    3. There are no hotspots found on the final product.
    4. The fluid dryers guarantee a homogenous and faster drying process.
    5. These dryers suit the best for the products that are heat sensitive.
    6. They have proved to be efficient in the drying of the granules and wet particles.
    7. These are easy to use and do not require much labor.
