MDLGV - Indústria Ltda: processo produtivo de whey protein

Abstract

The food supplements were highlighted few decades ago due to some people difficulties to supply their nutrients needs through their feeding. Whey Protein is a powdered food supplement that consists in a concentrated of proteins, whose is used as the main feedstock to produce whey. The process consists in an evaporation equipment, the filtration using membranes (microfiltration and ultrafiltration) to concentrate and remove sugars and fats present in the serum and finally a atomizer (Spray Dryer). The current industry will have two products being sold, the Concentrated Whey Protein (WPC) and Isolated Whey Protein (WPI). In the present project the material balance was made in order to know the amount processed in each equipment based on the daily production preset, as well as the amount of waste produced. The second balance in the present work was the energetic balance, with the purpose of quantifying the utilities required for the development of the entire processing sector. The effluents generated in the process will be treated through stabilization ponds and an activated sludge system. The solid waste generated in the process will be destinated to an industrial landfill. After the final material and energy calculations, it was possible to quote the necessary equipments in the MDLGV company, as well as to do the financial study of the industry in order to verify if it is possible the development and billing intended by the company, besides indicating the level of attractiveness of the business. In the face of all the development it was possible to realize that the payback process would take about 7 years.
