Do you know what a paddle dryer is? If you run a pharmaceutical, food, chemical, or petrochemical industry, you might know what a paddle dryer is.
For those who don’t know, paddle dryers are versatile equipment that can dry, heat, and cool. This machine is designed to handle various materials like slurries, sludges, suspensions, granules, powders, and pastes.
Beyond drying, these paddle dryers are also used for agglomeration, granulation, alkalization, and sterilization processes.
Paddle dryers are available in a range of options, from standard ones to rotary vacuum paddle dryers, each meticulously designed to meet specific drying requirements.
So, if you want to know about the different types of paddle dryers, here’s a blog for you.
But before we understand the different types of paddle dryers, let’s first understand how they work and their key features.
How Does a Paddle Dryer Work?
The working principle of a paddle dryer is pretty simple. As the name suggests, the material enters the dryer and comes in contact with heated paddles and walls. These paddles are mounted on a rotating shaft and continuously move and agitate the material.
The heat of the hot paddles and walls is indirectly transferred into the material, evaporating moisture. This moisture is then removed via an exhaust system, resulting in a dry, processed product.
Types of Paddle Dryers
Vacuum Rotary Paddle Dryer
First on the list is a vacuum rotary paddle dryer from Thermosag. This type of dryer is preferred for heat-sensitive materials and delicate products. Operating under vacuum conditions significantly reduces drying temperatures, preventing thermal degradation of sensitive products.
Key Features
- Self-cleaning feature: The rotary vacuum paddle dryer has self-cleaning capabilities, reducing downtime and maintenance costs.
- Low-temperature Drying: This dryer offers a vacuum setting to dry products at reduced temperatures, safeguarding heat-sensitive materials.
Standard Paddle Dryer
One of the most common types of paddle dryers is the standard paddle dryer, best known for drying sludges and various materials. Its rotating paddle ensures thorough mixing, while heated paddles promote uniform heat distribution.
Key Features
- Uniform Drying: The product is mixed continuously to ensure it is evenly heated for consistent drying.
- Versatility: Suitable for drying a wide range of materials, including sludge, chemicals, and food products.
