With a Screw Heat Exchanger
The design of a heating screw is largely determined by the product itself (flow properties such as stickiness and physical characteristics such as thermal conductivity) and the desired final temperature. Zoning (ATEX) also significantly influences the choice of heating method and overall design.
For stable and efficient heating of bulk materials, even at high temperatures and with complex product characteristics.
When designing a heating system, the required heat transfer surface is calculated based on product properties such as specific heat, morphology, and bulk density. The desired final temperature and the chosen heating medium (such as steam or oil) also play an important role.
For products with poor thermal conductivity, it is essential that all particles come into contact with the heated surface. Depending on the material, this can be achieved using a paddle shaft, additional mixing paddles, or a carré system with two intermeshing screw augers for intensive mixing.
