The Paddle Dryer, developed and supplied by NARA, is an indirect dryer. It offers a wide range of possibilities for material treatment. The NPD is applied to dry, heat or cool organic or inorganic pellets, granules and powders. Filter cakes, thick pastes and even thick slurries having a sticky phase to pass during processing are handled in the machine. The raw material temperature changes when it gets into direct contact with the revolving, wedge-shaped rotating paddles and the jacket. All powder contacted surfaces are heated or cooled. Actually there are plants running with heating areas from 1,5 up to 280 m² and effective volumes between 0,0089 and 34 m³.
The NARA Paddle Dryer is well known for its compact construction and the consequently small need of installation space. This results from the high heat transfer coefficient and heat efficiency. These features combined with the self-cleaning effect of the paddles assure a homogeneous product, cooling or heating process for continuous and/or batch unit operations.

Pharmaceutical Dryers

Dryers are used in a variety of industries, such as the food processing, pharmaceutical, paper, pollution control and agricultural sectors. Diverse materials need to be dried in completely different businesses, such as chemicals for research and medical concerns, paper for printing and packaging operations and edible materials for further processing into popular foods and snacks.

Dryers are used to remove liquids or moisture from bulk solids, powders, parts, continuous sheets or other liquids by evaporation or sublimation. Dryers can be broken up into two main types: direct and indirect. Direct dryers convectively heat a product through direct contact with heated air, gas or a combusted gas product. Indirect dryers conductively heat a product through contact with a heated wall.

There are various types of Dryer used in Pharmaceutical Industries

crystallization with tray driers (vacuum):

The wet solids obtained were then re-slurried in 5 L of ethyl acetate and stirred for 30 minutes at -50C. Then the slurry was filtered and suck dried. Further the solids were dried in **Vacuum Tray drier below 450C.**

**The TGS crystals** obtained were tested for purity and particle size. The purity was found to be 99.23% by HPLC and particle size distribution at 90% is below 10 microns and mean particle size is 4.2 micron. The overall yield from the process was found to be 80%. The mother liquor from the process was recycled.
