Pasteurization / sterilization

Sterilization and pasteurization

In the case of dry products such as cereals, spices, herbs and flour, contamination occurs as soon as they are grown, harvested or dried by producers. It is highly dependent on climatic conditions and technical resources, which can be very basic on the smallest farms.

Co-operatives and processing plants therefore receive batches of very variable quality, which must be standardised before they can be marketed and used by consumers.

The process

Our Safesteril® sterilisation technology is installed worldwide and recognised for its effectiveness on powdered products, ranging from micronised powder to particles up to 5 cm in length.

Thanks to homogeneous treatment due to non-static exposure to steam and the non-condensation of steam on the product, Safesteril® has minimal impact on colour and other heat-sensitive properties.

Pathogens are completely inactivated: yeast, mould, enterobacteria, coliforms, salmonella, and the total flora is greatly reduced.

Taste, colour and moisture are preserved during the process, and the loss of volatile oils is less than 5-10%.

The design and instrumentation of the Safesteril® line make it possible to determine in real time the treatment scale (time/temperature) applied to the product as it passes through the Spirajoule® heating screw, and to automatically bypass any water that has not undergone sufficient treatment. This safety system ensures that at no time is insufficiently treated product transferred at the end of the process to a bagging or bulk storage unit for theoretically sterilised product.

Grâce à un traitement homogène dû à une exposition non-statique à la vapeur et à la non-condensation de la vapeur sur le produit, Safesteril® possède un impact minimal sur la couleur et les autres propriétés sensibles à la chaleur.

Les agents pathogènes sont ainsi entièrement inactivés : levure, moisissure, entérobactéries, coliformes, salmonelles, et la flore totale est fortement réduite.

Le goût, la couleur et l’humidité sont préservés au cours du process et la perte en huiles volatiles est inférieure à 5-10%.

Le design et l’instrumentation de la ligne Safesteril® permettent de déterminer en temps réel le barème de traitement (temps / température) appliqué au produit au cours de son passage dans la vis chauffante Spirajoule® et de bypasser automatiquement toute l’eau qui n’aurait pas subi un traitement suffisant. Cette sécurité garantit qu’à aucun moment du produit insuffisamment traité ne soit transféré en sortie de procédé, vers une unité d’ensachage ou de stockage en vrac de produit théoriquement stérilisé.

A SOLUTION TAILORED TO YOUR NEEDS

Because every environment or product need is different, ETIA designs unique solutions tailored to your specifications and based on a technical assessment. Operating and production costs are variable and depend on where the line is installed, the capacity and the depreciation method. As a result, we can say that profitability is visible after one year, and sometimes even less.

The use of existing auxiliaries (steam, dry air, chilled water) is possible and can help to reduce the cost of the investment.

Safesteril® covers a wide range of capacities from 50 – 3,000 kg/hour (110 – 6,600 lbs / hour).
