Advantages and disadvantages
Advantages
The screw heat exchanger has a large number of advantages in comparison to other heat exchangers.
Very flexible to control | |
Can be made from almost any construction material | |
Is a continuing process | |
Processing very small granumetric fractions is possible. | |
Processing paste-like masses is possible. | |
"Closed" system (toxics, steam, dust) | |
Energy efficient due to indirect heat transfer | |
Little to no dust formation | |
Easy to clean | |
Buffer possibility |
Disadvantages
The screw heat exchanger also has a number of disadvantages in comparison to other heat exchangers.
Drying below 1% humidity is possible but hard | |
The maximum ability to evaporate humidity is around 600 l/h. | |
Cannot be applied to a product that is large and/or sensitive to breaking | |
Sticking and scaling of the product to the heat transferring surface | |
Relatively low heat transfer coefficient | |
In case of leakage thermal medium in the product |
