Skyline Air Tray Dryer
A tray dryer in the pharmaceutical industry is used to dry Powers, granules, and other types of materials. It consists of a heated chamber with trays to place materials.
The trays are usually stacked one on top of each other, and the drying process is usually done under controlled temperature and humidity conditions.
The principle of a tray dryer is based on the process of convection drying.
Working Principles
>> Wet solid is loaded into trays.
>> Place the tray in the chamber.
>> Fresh air is introduced through the inlet, which passes through the heaters and gets heated up.
>> The hot air is circulated by means of fans at 2 to 5 m/s.
>> The water is picked up by air.
>> As the water evaporated from the surface, the water diffuses from the interior of the solid by capillary action.
>> These events occur in a single pass of air.
>> The time of contact is short and the amount of water picked up in a single pass is small.
>> Moist air is discharged through the outlet. thus constant temperature and uniform airflow over the material can be maintained for achieving uniform drying.
Features
- In tray dryer, handling of materials (loading and unloading) can be done without losses
- Most efficient and consume less energy
- As it is available in different sizes with different price ranges, so its becomes easy to control capital cost
- It can be used on small scale as well as on a medium scale
- It reduces the drying time by removing moisture at an efficient rate
- Easy to operate and handle
- Easy to installed
