REVTECH SAS

Revtech supplies custom-made industrial solutions for the heat treatment of bulk solids, powders and gases. It has installed over 150 industrial units worldwide.

Our unique technology can be used for various applications simply by adapting the operating parameters of the machine:

Chemical & Fine Chemical Market:

• Preheating – sodium chlorate…
• Drying – sands, clay, salt, limestone, PET, alumina, potash sulfate, nitrate, calcium, manganese, pigments, iron oxide…
• Ultra-drying: H₂O < 0.1 % – alumina, silica, zeolites, MMCs, molecular sieves, glass microspheres, corrosive powders…
• Calcination – metal oxides, silicates, adsorbents, bentonites, pharmaceutical waste…
• Thermal desorption – catalysts, contaminated soils, foundry sands, synthetic rubber, FMO, pumice based absorbents, cork, formaldehyde resin, Sulfur Pellets, synthesis polymers…
• Sintering – metal oxides, zeolites…
• Stripping – corks…
• Gas-solid reaction – catalyst activation, regeneration, preparation…
• Sterilization – pharmaceutical products…

Biomass Market:

• Torrefaction – biomass
• Pyrolysis – wood, agricultural waste…

Food Market:

• Pasteurization – herbs, spices, botanicals, flour, grains, seeds and nuts
• Stabilization – cereal products (germs, brans, flour…) and enzymatic inhibition of seeds and beans
• Drying – flour, grains, flakes or any part of cereals
• Toasting & roasting – flour, malt, flakes, grains/seeds like wheat, sesame, sunflower, soya, nuts…
• Puffing – grains
• Heat treating – flour to modify its properties (viscosity modification via protein denaturation…).

The technology is based on simple principles:

• Gentle transport & homogeneous mixing in a closed spiral tube by vibrations,
• Heating by direct contact with an electrical  impedance tube,
• Heat treatment in a confined and controlled atmosphere.

Revtech can supply continuous units from 200 kg/h to 5 ton/h.
