Implementação de uma unidade industrial para produção de requeijão com doce de abóbora

Este trabalho consiste na apresentação de um projeto, elaborado no âmbito académico da disciplina de Equipamentos e Instalações Industriais do curso de Engenharia Alimentar da Escola Superior Agrária de Viseu, que visa a implementação de uma unidade para produção de Requeijão com Doce de Abóbora. Inicialmente faz-se um breve enquadramento e descrição do processo que vai ser utilizado para a produção industrial. Depois apresentam-se alguns aspetos relacionados com a empresa o respetivos recursos humanos, seguindo-se-lhe a parte técnica que compreende as componentes de elaboração de balanços mássicos e diagramas de fabrico, equipamentos, layout e plantas e considerações relativas aos resíduos e/ou efluentes. Por fim é feita uma avaliação de viabilidade, baseada numa análise económica simplificada

Diagnosis. Males of Ctenus nigritus resemble those of C. manauara (Höfer et al. 1994: fig. 7 a–b) by the prominent ventral tegular projection, but can be distinguished by the larger RTA, which is truncated at the apex, and the shape of the retrolateral tibial apophysis (Figs 3 A–B).
