Steam sterilization has become an unavoidable issue with food products and it forces industry to revisit their entire production lines, in order to comply with the ever-increasing requirements of European Standards.
 
Consumers turn increasingly to food products with a guaranteed or "organic" origin. Recent sterilization processes such as ethylene oxide or ionisation are incompatible with these demands, encouraging the development of innovative processes based on traditional methods such as steam. The REVTECH technology uses steam for its efficiency in the elimination of bacteria and clean electric energy in order to heat the product. Overall steam consumption is therefore significantly less than competing technology, resulting in improved product quality, especially in the domain of aromatically rich herbs, spices and medicinal plants. Less steam will be injected into the system, lower will be the leaching effect of the steam on the surface of the product. Even the most fragile products such as oregano or parsley see their color maintained after treatment.
 
McCormick, the major international herbs and spices distributor uses a complete steam sterilization system designed and built by REVTECH. Ducros, the French subsidiary of the McCormick group, made the ambitious gamble to invest in the innovative REVTECH process over seven years ago when suspicions first arose about the future in Europe of processes involving radiation. The unit installed includes two REVTECH devices for the steam sterilization under superheated steam, and the drying and cooling to ambient temperature of a wide range of products.

Last year, some famous spice company all around the world successfully trusted in innovative Revtech technology such as the russian leader and the leader in Thailand.

Investment costs and operating costs are particularly low with REVTECH technology. The quality of products treated with the REVTECH process is significantly improved when compared to products treated in traditional systems such as steam-heated autoclaves. As heat is provided by contact with the tube and steam is used only for its steam sterilization properties, wetting of the product is minimal flavour loss is kept well within the allowed standards.

For drying and cooling, TPC is associated with vibrations to obtain high coefficients of thermal transfer between the material and the heated tube. The amount of air used is reduced to levels necessary only for the removal of humidity released by the material itself. A water/ethylene glycol mix is used in the cooling system to remove heat and to obtain a constant temperature of the material as it leaves the system.
 

Other companies also use this technology for steam sterilization.

For example, the pharmaceutical industry uses the REVTECH process for the steam sterilization of natural gums, notoriously difficult to treat because of their excessive stickiness and their sensitivity to heat.
Two complete systems have also been installed for the treatment of medicinal plants.
