Drying of a porous material in a pulsed fluid bed dryer: The influences of temperature, frequency of pulsation, and air flow rate (Artigo de Periódico)
(2009)In this work, a four-section pulsed fluid bed apparatus with a 0.18 m2 cross-section area was used to investigate the influence of pulsed-fluidization variables on the drying process of molecular sieves, a test material ... -
Drying of beans in a pulsed fluid bed dryer: Drying kinetics, fluid-dynamic study and comparisons with conventional fluidization (Artigo de Periódico)
(2007)Fresh carioca beans (Phaseolus vulgaris) were submitted to convective drying in a pulsed fluidized bed (PFB) dryer. A full factorial design was developed in order to analyze the effects of the following process variables ... -
Drying of sodium acetate in a pulsed fluid bed dryer (Artigo de Periódico)
(2010)Sodium acetate crystals obtained from the reaction of acetic acid with sodium hydroxide are usually dried in rotary or fluidized beds. In this study, a batch pulsed fluid bed dryer with a 0.18 m2 cross-sectional area was ... -
Enteric coating process of diclofenac sodium pellets in a fluid bed coater with a wurster insert: Influence of process variables on coating performance and release profile (Artigo de Periódico)
(2013)The objective of this work was to study the coating process of diclofenac sodium pellets, with the commercial aqueous coating suspension for enteric release-Acryl-Eze® MP, in a fluid bed coater with a Wurster insert. Coating ... -
Evaluation of fermentation parameters during high-gravity beer production (Artigo de Periódico)
(Assoc. Brasiliera de Eng. Quimica / Braz. Soc. Chem. Eng., 2001)A large number of advantages are obtained from the use of highly concentrated worts during the production of beer in a process referred to as "high-gravity". However, problems related to slow or stuck fermentations, which ... -
Film coating of theophylline pellets in a pulsed fluid bed coater (Artigo de Periódico)
(Elsevier, 2008)A four-section pulsed fluid bed (PFB) dryer was employed in the film coating of granules. Particles of 1.28 and 1.62 mean diameter, containing, respectively, 6.8 and 9.2% of theophylline, were coated with a commercial ... -
High-gravity brewing utilizing factorial design (Artigo de Periódico)
(ABEQ, 2000)A number of factors can influence the behavior of yeast during fermentation. Some of these factors (initial wort concentration, initial pH and percentage of corn syrup in the composition of the wort) were studied in order ... -
MQL strategies applied in Ti-6Al-4V alloy milling-Comparative analysis between experimental design and artificial neural networks (Artigo de Periódico)
(MDPI AG, 2020)This paper presents a study of the Ti-6Al-4V alloy milling under different lubrication conditions, using the minimum quantity lubrication approach. The chosen material is widely used in the industry due to its properties, ... -
A protein powder agglomeration process using açaí pulp as the binder: An analysis of the process parameters (Artigo de Periódico)
(Elsevier B.V., 2020)This work investigated the fluidized bed agglomeration of a plant protein powder blend using an açaí pulp binder in order to improve the physical and handling properties. The blend was prepared mixing isolated pea protein ...
