Components for thermal processes

We propose a wide range of products and components for industrial bulk materials processing: heating, roasting, drying, cooling and many more.

SPIRAJOULE®

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.

Continuous cooling screw

UPK-C® is a continuous cooling screw conveyor for bulks, powders, granulates, pasty or muddy products. The cooling function is accomplished through chilled water into the screw and double jacket.

Advantages:

  • Flash cooling
  • Easy cleaning
  • Perfect mixing and homogeneous treatment guaranteed by paddles

Continuous heating screw

UPK-H® is a continuous heating screw conveyor for bulks, powders, granulates, pasty or muddy products. The heating function is accomplished through hot water, steam or other thermal fluid passage into the screw and double jacket.

Advantages:

  • Flash heating
  • Easy cleaning
  • Perfect mixing and homogeneous treatment guaranteed by paddles
