There are countless applications, the technology is the same: the Screw heat exchanger

The screw heat exchanger is an indirect heat exchanger based on a conveyor screw and is used for cooling, heating and drying powders and granules. In the case of equipment with indirect heat transfer, the heating or cooling medium is separated from the product by means of a wall.

There are countless applications. Products vary from cooling sand to drying starch. Heat transfer is carried out via the trough wall, screw shaft, screw blade or a combination of these. During transport the material is cooled, heated or dried.

The screw heat exchanger is produced in various sizes depending on what the process requires and the space available. There are variations in length as well as in diameter. The construction materials used are matched to the requirements of the product or the wishes of the customer. Different thermal fluids are used to supply or remove energy. For cooling for example: water, glycol, liquid nitrogen and for heating: water or thermal oil.

If the screw heat exchanger is used for drying products it is important that there is sufficient ventilation to remove the moisture given off during drying. Due to the indirect drying the quantity of ventilation air is limited.
