electrical heating screw conveyor

Spirajoule® is a heated, coreless screw manufactured to provide optimal thermal transfer to a variety of finely divided wet and dry products. Maximum efficiency is achieved through the product direct contact with the electrically heated screw. Product dwell time, temperature and air extraction are easyly adjusted. Full inspection of internal chamber allows for easy cleaning and quick product change over. Spirajoule® also allows for the injection of steam or dry air.
