The Spirajoule® technology is an exclusive process for thermal treatment. It is designed with a worm screw conveyor electrically heated by a low voltage current.
The screw heat the product due to the Joule effect. The product temperature is precisely controlled due to the regulation of the screw temperature setting. The dwell time is regulated by the setting of the screw rotation speed.
The technology is a simple and economical process with the accurate and efficient operation of the heat treatment up to 800°C of wet or dried products.
