Simulation of Water Evaporation on Ultimonitored Thermomix®: Potential Approach for Studies on Milk Evaporation

Abstract

It was simulated the industrial evaporation process using a multi-monitored Thermomix ® . To validate the hypothesis that this equipment could act as a laboratory-scale evaporator, we evaporated water from milk to produce dulce de leche. Using this equipment, we were able to precisely determine mass changes throughout the process, observe the effect of the exhaust system on the evaporation, obtain dulce de leche with market composition, and determine the effect of sugar addition on water evaporation. The error between the observed boiling point temperature and that predicted by theory was ~ 2%; as a consequence, the equipment could be used to establish Dühring curves. It was found that the Thermomix ® multi-monitored configuration was a simple and inexpensive equipment for simulate evaporation in industrial dulce de leche production.Keywords: laboratory scale; concentration; dulce de leche; boiling point. RESUMOFoi simulado o processo de evaporação industrial usando um Thermomix ® multi-monitorado. Para validar a hipótese de que este equipamento poderia funcionar como um evaporador em escala laboratorial, evaporou-se água do leite para produzir doce de leite. Usando este equipamento, pôde-se determinar com precisão as mudanças de massa ao longo do processo, observar o efeito do sistema de escape na evaporação, obter o doce de leite com a composição do mercado e determinar o efeito da adição de açúcar na evaporação da água. O erro entre a temperatura do ponto de ebulição observado e o previsto pela teoria foi de ~ 2 %; Como consequência, o equipamento poderia ser usado para estabelecer curvas de Dühring. Descobriu-se que a configuração multi-monitorada Thermomix ® foi um meio simples e barato de simular a evaporação na produção industrial de doce de leite.Palavras-chave: escala laboratorial; concentração; doce de leite; ponto de ebulição.

Influence of sucrose reduction on fouling during the production of dulce de leche

“…The production of DL for research generates an economical expense in relation to energy and raw materials, in addition to longer manufacturing times when compared with industrial scale production lines. To avoid these problems, a process simulator as characterized in the literature was used in the laboratory resulting in quick and economical production of DL within the parameters of legislation (Stephani et al ., 2017). The representative results found by Francisquini et al .…”
