The vacuum cooking process gently cooks and simmers products at temperatures below the equivalent atmospheric temperature. Processing under vacuum enables quick evaporation of moisture from the product at much lower temperature (50˚C to 85˚C) than atmospheric (100˚C), thus preserving the natural flavours,

Petroleum coke, a byproduct from the cracking of petroleum that is practically pure carbon in composition, is used in the heating process.
Our Preheaters are responsible for the heating process, which involves heating the petcoke from a minimum of 0°C to around 200°C.
An electric mixer kneads the heated petroleum coke and hot pitch together until a paste is created, which is then shaped into blocks.
We provide unique solutions for each specific field of application and cover the entire process portfolio, including cooling-off bulk-solids such as, for e.g., bed-ashes, drying of sludges or pastures, and heating-off, such as petcoke for the anode-lines of the aluminium industry, among other applications.
Our Screw Heat Exchangers vary substantially from the usual versions available on the market due to the fact that they use the well-proven Hollow-Flight Principle, which contains a number of advantageous characteristics.
