Many dry products need to be pasteurised or sterilised. Many old methods like irradiation, ozone and UV are still used to sterilise dry products. Though they do add life to the products, these methods fail to protect the taste, flavour, consistency and nutrition of the products. However, steam sterilisation is the only efficient and globally recognised solution.

Safesteril Sterilizer was developed and patented by ETIA, a French engineering company founded in 1989. Safesteril technology is based on the unique and patented combination of an electrically heated conveyor with steam, that reduces germ content with a minimal alteration of its properties. It is an equipment that increases shelf life, by the killing/deactivation of bacteria available in dry products like yeast, mold, enterobacteriaceae, coliforms, salmonella, etc. keeping its natural properties intact.

We at Rieco are pleased to reach into a new arena of sterilization with the best technology of sterilisers with ETIA, France. The patented electrical heating of screw warms upto 250 degree Celsius for safe removal of Pathogens and highly dangerous bacteria and viruses from the spices/ food as per global norms. With systems installed in more than 35 countries, Safesteril is the leading solution for the continuous steam pasteurization and sterilization of your dehydrated products of all shapes – powder, granulated, crushed, shopped, flakes, whole and more.

Working Principle:

Safesteril Products | Rieco
  • Feed Hopper: (500L and 1000L capacity) Slow motion dosing screw smoothly and continuously feeds the product into the sterilization chamber without breaking particles.
  • Sterilization/Pasteurization: Product is gently conveyed through the chamber by a screw heated by Joule effect. Germ reduction is achieved due to the combination of the screw heat and the steam injected. Steam can be saturated or dry according to the treatment to be achieved and allows a perfect control of the moisture. A transformer delivers the electrical power that heats the screw.
  • Transfer / By-Pass Screw: The transfer screw is controlled by an exclusive “auto- reverse” feature, that guarantees only the product that reaches the target temperature and time conditions goes into the cooler. The product can be transferred into the cooling screw or bypassed in a bag for reuse.
  • Dry Flash Cooling: The product is cooled down in a cold and dry atmosphere. Cooling is done by the action of a chilled water circulating inside the screw and the auger jacket. A dehumidified air is injected inside to get rid of the excess moisture. The material can be packed online, no need to regrind the powders.
  • Safesteril is a versatile process that not only can perform pasteurization and sterilization, but also disinfect, dry and roast.
  • Safesteril achieves high performance of microbial load reduction, while maintaining the organoleptic properties of the products – taste, color and moisture are preserved.
  • Volatile oil loss is less than 5-10%, which is less than with any other steam treatment systems
  • A 5-log reduction of Salmonella and a significant reduction of spores content are also guaranteed.
  • During sterilisation 5 logs reduction for TPC and other germs including pathogens such as Yeast, Mold, Enterobacteriaceae (E.Coli), Coliforms, Salmonella are entirely inactivated.
  • While sterilization in the process, SAFESTERIL makes sure to protect flavor, colour, consistency, nutrition, aroma and give maximum value.
