On large industrial scales, the cooling stage in the production process of hard candies is one of the most critical unit operations. The main problems affecting final hard candies quality as regards the cooling process are: deformation, fragility and aggregation. The main operating conditions of the cooling stage are temperature and velocity of cooling air as well as the residence time of candy inside the tunnel.The objective of this work is to study the influence of process operating conditions and candy composition on the unsteady behavior of the cooling process of hard candies to improve final product quality.The study is conducted by using a simple mathematical model which was implemented and solved by using gPROMS (general Process Modeling System). A detailed discussion of results is presented through several examples. 相似文献

This review paper provides an overview regarding the main aspects of microbial lipases production. The most important microbial
lipase-producing strains for submerged and solid-state fermentations are reviewed as well as the main substrates, including
the use of agroindustrial residues. Current process techniques (batch, repeated-batch, fed-batch, and continuous mode) are
discussed and the main bioreactors configurations are also presented. Furthermore, the present review paper shows a general
overview about the development of mathematical models applied to lipase production. Finally, some future perspectives on lipase
production are discussed with special emphasis on lipase engineering and the use of mathematical models as a useful tool for
process improvement and control. 相似文献
