New Surdry Continuous Sterilizer

The steam consumption is reduced up to 50% compared to batch retorts, as no water or steel mass needs to be reheated and recooled every 1-2 hours. The stop-start to change the package format costs little energy and water compared to other continuous systems and is quick and easy.

With the condition of a single counterpressure, the sterilizer can accept baskets with cans, glass jars or bottles, pouches, carton packs and rigid plastic packs. It is also ideally suited for pasteurization in thin profile plastic cups or trays. A low counterpressure will allow to get to 100 ºC (212 ºF) or higher with no risk of seal damage or package deformation.

In addition to the very low level of mechanical complexity, the sterilizer is accesible through doors on both ends. The standard 1.8 mts diameter Shell provides comfortable and low risk access.

Containers are loaded in baskets or trays using conventional or robotic loaders and unloaders of the same kind as used for batch retorts. Existing equipment may be adapted to this continuous sterilizer.

The sterilizer is loaded with a basket or stack of trays every 2 minutes or more, matching the filling speed. Put 2,000 cans per 1 m3 or 35 cu-ft basket in 2 minutes and the line speed will be up to 1.000 cans per minute. High temperature, short time processing will do the rest in a horizontal tunnel designed for a wide range of heating and cooling times.
