Análise da secagem convectiva de folhas de manjericão (Ocimum basilicum L.)
(Universidade Federal de São Carlos, 2013-03-19)
Convective drying of leaves involves heat and mass transfer in packed-beds of deformable material, since the leaves shrink significantly when the moisture is removed. Therefore, the packing structure changes over time, and ...
Secagem de pimenta-do-reino preta (Piper nigrum L.) em secador de leito fixo
(Universidade Federal de São Carlos, 2015-08-27)
The black pepper is the most important spice commercialized globally, with Brazil being one of the main producers in the world. Yet few studies to optimize the production of this commodity process have been found in the ...
Análise do desempenho do leito vibrofluidizado na secagem de pasta
(Universidade Federal de São Carlos, 2017-05-05)
The agitation promoted by the vibrofluidized bed allows the incorporation of several unitary operations such as granulation, coating of particle, drying of grains, and the drying of pasty materials. However, it is necessary ...
Secagem de materiais pastosos e granulares no leito de jorro mecânico e convencional
(Universidade Federal de São Carlos, 2017-06-02)
This study had the objective to assess the behavior of a mechanically spouted bed compared to a conventional spouted bed through attrition of particulate matter, thermal and mass analysis during water evaporation and through ...
Acúmulo, elutriação e recuperação do produto na secagem de pasta em leito de jorro
(Universidade Federal de São Carlos, 2018-03-09)
One of the equipment that has been highlighting mainly in the drying of pastes and solutions is the spouted bed. In this type of equipment some factors that can make it impossible to use are operational problems caused by ...
Secagem de cevada: análise da anatomia e do meio de transporte
(Universidade Federal de São Carlos, 2018-03-23)
Despite the recent motivations for application in the food industry, the characterization of polished barley grains is still scarce in the literature. In this way, the objective of this work was the experimental analysis ...
Avaliação por CFD da fluidodinâmica e da transferência de calor em leitos de jorro para diferentes ângulos da base cônica
(Universidade Federal de São Carlos, 2019-02-27)
The spouted bed is an equipment that provides fluid-particle contact due to the cyclic movement of solids in its interior, which results in high rates of heat and mass transfer between phases. The spouted bed is used in ...
Secagem convectiva de folhas visando a obtenção de compostos bioativos via extração supercrítica
(Universidade Federal de São Carlos, 2019-04-11)
In this work, an investigation through experimentation and mathematical modeling was carried out with the intention of evaluating the drying process of pitangueira (Eugenia uniflora L.) and olive tree (Olea europaea L.) ...
Secagem em leito fixo de materiais granulares com diferentes esfericidades
(Universidade Federal de São Carlos, 2019-02-19)
The drying process of particulate biological materials in fixed bed is influenced by several factors associated with the particles and the bed packing. The main objective of this research was to evaluate the drying of ...
Secagem de pimenta dedo-de-moça (Capsicum baccatum var. pendulum) em secador convectivo horizontal
(Universidade Federal de São Carlos, 2010-05-28)
The cultivation of pepper is widespread in Brazil since its colonization. This plant, besides being much appreciated in the cuisine has proven pharmacological effects such as lowering cholesterol, inhibiting appetite and ...
