This paper presents the design of a system for pasteurizing goat milk as a part of a process for artisan elaboration of cheese. The system consists in a Fresnel type concentrator used for cooking large  amounts of food with a vaporizer located in the focus. The steam bubbles into the isolated container where  the milk is cooked by a double boiler. When the desired temperature is reached, the steam flow is closed and the milk remains in this condition for  30 minutes into the closed container. Pasteurizing of 10 liters of milk is done in about one hour. The project  onsiders guidelines for achieving a successful transference.
