Heat treatment of cereal products

Revtech combines heating by direct contact with an impedance tube and vibration transport to process all kinds of cereal products.

In one machine all kinds of ingredients can be treated:

  • Seeds: sunflower seeds, sesame seeds, linseeds, pumkin seeds...
  • Cereals: barley, malt, oat, rye, corn
  • Bran
  • Germs
  • Flour
Revtech pasteurization of seeds, barley, flour

Our applications

Toasting - Roasting > Read more

  • Improved roasted flavor:
    • Due to treatment in a confined atmosphere,
    • Due to roasting with direct contact with a hot surface, similar to traditional technologies.
  • Good homogeneity and precise control of the roasting intensity. Below is an example of toasted bran:

roasted bran

Pasteurization > Read more

  • Continuous and fully automated process avoiding recontamination
  • Validated and guaranteed microbiology quality:
    • Complete eradication of pathogens (Salmonella, E Coli, Coliforms, yeasts and moulds…) and high reduction of the total plate count,
    • Technology recognized by the Almond Board of California.
  • Preservation of the product quality:
Pasteurization of sesame seeds

Enzymatic inhibition - Stabilization > Read more

  • The combination of heat, steam and perfect mixing guarantees the deactivation of the germination process with:
    • Very uniform treatment,
    • Very good preservation of the organoleptic properties,
    • Visual aspect remains intact.
  • This application is possible for all kinds of grains, wheat, corn, soya beans and even flour.

Drying - Heat treatment > Read more

  • The combination of heat, steam and perfect mixing enables to modify the properties of the product:
    • Change of the viscosity of the flour for example,
    • Heat treatment for cake flour...
  • This application is possible for all kinds of grains and flour.


Oustanding benefits for your factory

  • Cleaning is vastly simplified – No dead zones in the machine, just a smooth stainless steel pipe easy to clean with CIP techniques.
  • Easy gas exhaust handling – Products are heated by direct contact with the hot spiral tube, not by hot air, leading to much less gas to treat at the exhaust.
  • No fire risk – There is much less air in movement than in a traditional roaster. The operation without oxygen is even possible.
  • Energy efficiency – Around 90% of the energy is transferred to the product compared to 30-40% with gas roasters.
