Thermal treatment systems for doypack, stand-up pouch, and baby food are based on a two-stage process designed to ensure the safety and quality of the packaged product.
The first phase involves heating the product and the packaging itself (doypack, food pouch, or generic pouch for adults and children). More than simple pasteurization, this phase consists of maintaining the temperature above 85°C for a minimum of 5 minutes.
The treatment parameters, such as time and temperature, are studied based on the specific composition of the product or the doypack: the recipe, pH, and fat concentration influence the operating conditions.
Pasteurization is particularly important for products that, after filling, may still contain parts or components at risk. The goal is to ensure that all critical areas, such as the folds of the package and the cap corrugations, are exposed to high temperatures for the necessary time to eliminate any bacteria.
Thanks to Sarp spirals, both the internal content and the packaging itself are safe at the end of the process.
Products used for this application
After the pasteurization phase, the product undergoes controlled cooling, essential for rapidly reducing the temperature and allowing subsequent handling and packaging.
This cooling, which can last 20 minutes or more, can be performed with air spirals, where controlled airflows act as heat exchangers, or with water spirals, which ensure faster thermal reduction thanks to superior heat exchange. Water cooling involves managing the presence of water in the system and on the product, so this aspect must be evaluated based on specific production needs. In both cases, the thermal treatment ensures that the product can be safely transferred to secondary packaging and shipping.
