Resumo(s)
This thesis portrays the scale up process of the semi-sweet biscuit production Newkcal from the pilot to industrial scale, highlighting occurred troubles, respective possible causes and the solutions adopted to solve them. These solutions resulted in modifications of the recipe and the biscuit manufacturing process, such as: reducing the total weight of Newkcal dough; opting for a three stage formulation of the dough; production of two different Newkcal formats with different production line speeds; changing the position of the cutting/engraving molds of the dough.
The parameters and standards were stipulated for each stage of the manufacturing process. The final product specifications were reset by adjusting the specifications pre-defined while the biscuit production was at a pilot scale: the length and thickness of the biscuit decreased slightly and the width and moisture were increased.
The Newkcal biscuit is considered an improvement of the recipe and production process of a previous one: Fruit & Fit. The characteristics of both biscuits were compared and it was verified that Newkcal biscuit has a more compact and less porous structure and is softer than the Fruit & Fit biscuit.
