Abstract

The present work was carried out with the aim of designing an industrial lactic acid plant that would use the residual whey from the processes of the dairy industries of the canton of Santa Ana, located in the province of Manabí, as a substrate. The investigation was begun by calculating the potential annual demand for lactic acid in the province of Manabí ($ 273,600), which represents 16% of the national market, taking this as a reference we set out to capture 10% of the local market ($ 27,360). A bibliographic investigation was carried out where it was determined that the best yield was 8.3% for the production of lactic acid from the fermentation of the whey using the bacterium lactobacillus bulgaricus as a microorganism. The stoichiometric balances of the biological equation, mass and energy balances were then made to produce 48 liters of lactic acid daily, which covers the proposed demand (10%). From this, the sizing of the plant was carried out and the respective flow diagrams, blocks and equipment that describe the production process were prepared.
