SonoSteam Treatment of Table- and Hatching-Egg

Table-egg

Egg is a unique and highly popular food product ingredient with many uses in traditional kitchens, both as cooked as well as raw product. However, improper kitchen hygiene and the use of unpasteurized raw eggs can cause food poisoning.  Because of the permeable nature of the egg shell, bacteria can sometimes reach the inner surface and contaminate eggs from the inside.

SonoSteam has designed a full-scale application for disinfection of table-egg. The technology uses only the combined effect from steam and ultrasound in a superfast continuous treatment of 1-2 seconds of exposure. The system can be installed directly on to the conveyor belt at the production site. The technology has demonstrated more than 5 logs reduction on surfaces of the egg shell, both outside and inside. The rapid treatment has no negative impact on egg quality.

Hatching-egg

It is particularly problematic when pathogenic bacteria from the surface of the shell reaches inside the hatching egg and contaminate the new chick. This could eventually lead to low hatching capacity or high mortality rate of newborn chicks. The infected chicken can cause infections of other healthy chickens and thereby the spread of the pathogen throughout the whole production chain. Control of pathogenic spread as early as possible is the key step to proper infection control.

The performance of SonoSteam treatment on hatching-eggs has been demonstrated in large factory trials on eggs from old hens. Results show positive effect from the SonoSteam treatment on the hatching capacity as well as the absent of pathogenic bacterial loads on eggs.

Industrial application

SonoSteam offers full-scale application for continuous decontamination of hatching- and table-egg.
Hatching-egg decontamination has a capacity of 120.000 eggs per hour, ideal for large production sites. The process can be integrated into most production plants or operate as a single standing unit.

Full scale process for table-egg disinfection fits most traditional production sites with large capacities. This technology is integrated directly unto conventional conveyor belt for egg processing and adjusted to the speed of the production plant.

All SonoSteam machines apply PLC system for easy access and control/monitoring of treatment parameters.
