1. Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte
Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperativ

2. Recobrimento de ureia em leito de jorro para minimizar as pedras de nitrogenio por volatilização / Coating of urea in spouted bed to decrease nitrogen volatilization
A uréia é o fertilizante nitrogenado mais utilizado no Brasil, e seu uso tem aumentado nas últimas décadas. O recobrimento das partículas de uréia é realizado, principalmente, para que o nitrogênio tenha uma liberação lenta, aumentando assim seu tempo de disponibilidade para as plantas. O objetivo deste trabalho foi recobrir os grânulos de uréia

3. Analise da secagem de residuo de leite de soja "Okara" em secadores de leito de jorro e de cilindro rotativo assistido a microondas / Drying of soy milk residue in the spouted bed dryer and rotary cylindrical dryer assisted by microwaves
The use of industrial residues has become more and more important to avoid the environment contamination and to make use of resources considered wastes in the chemical and food industries. Actually, the approximated soy milk production in the world is unknown; however, it is known that large amounts of its residue, named "Okara", are generated by its product

4. Identificação e monitoramento do regime fluidodinamico do leito de jorro no recobrimento de particulas / Identify and monitoring of flow regimes spouted bed coating of particles
The coating of particles in spouted has shown sufficiently promising, in view of its potential of applications in several products such as tablets, cosmetics, seeds, fertilizers. However, the works reported in literature had been predominantly based on visual observations, through columns constructed with transparent material, operated the pressure and ambie

5. Estudo experimental e de simulação da fluidodinâmica de um leito de jorro com tubo Draft
The spouted bed has been used in several processes as drying, granulation, catalytic polymerization, residues treatment and materials coating. This application is due to the excellent fluid-particle contact and to the characteristics of the solids circulation. In spite of its extensive application, the spouted bed has some scale-up limitations, so its necess

7. Estudo experimental e de simulação da fluidodinâmica e recobrimento em leito de jorro
The spouted bed technique has found application in many industrial processes such as drying of granular materials, blending of polymer chips, coating of tablets, and granulation of fertilizers and other materials. Although has an extensive application, the mechanisms of solids movement in spouted beds are still not completely understood. The knowledge of the

8. Identificação e monitoramento de regimes de escoamento em leito de jorro
Spouted bed has been studied intensively because of its potential of application in several processes. Identification and characterization of flow regimes in spouted bed based on visual observation have been reported in literature. However, the characterization of flow regimes based on visual observation is not either usual or possible in industrial equipmen

9. Controle e monitoramento em tempo real do regime de jorro estavel atraves da analise espectral / Control and monitoring on line of the steady regime in the spouted bed process by spectral analysis
This work describes the control and on line monitoring of the spouted bed steady regime using the gas-solid contact regimes identification method by pressure measurements. The work presents two main features: 1) the on line identification of fluid dynamic regimes in the spouted bed process based in the spectral analysis of the pressure fluctuations and 2) th

10. Estudo da secagem do feijão verde (Vigna unguiculata L. Walp) - análise experimental do processo combinado leito fixo/leito de jorro
Green bean is considered as one of most traditional Brazilian Northeast dishes. Green beans drying preliminary experiments show that combine processes, fixed-bed/spouted bed, resulted in dehydrated beans with uniform humidity and the recovery of the beans properties after their rehydration. From this assays was defined an initial humidity suited for the spou

11. Analise das influencias das caracteristicas do solido e da supensão no processo de recobrimento em leito de jorro
O recobrimento de partículas em leito de jorro tem aplicações em diversos produtos como comprimidos, cosméticos, alimentos, sementes, fertilizantes, etc. No processo de recobrimento o desempenho é dependente de um conjunto de características do sólido a ser recoberto, da suspensão de revestimento, da adesão líquido-sólido e das condições operaci

12. Estudo comparativo da produção de extrato seco de ´Bauhinia forficata` Link pelos processos ´spray-dryer` e leito de jorro / A comparative study of the production of dried extract of Bauhinia forficata Link by the spray-dryer and the spouted bed processes.
Este trabalho apresenta o desenvolvimento de uma metodologia experimental visando à produção de extrato seco padronizado de Bauhinia forficata Link. Um planejamento experimental de três fatores e três níveis tipo Box-Behnken e análise multi-resposta foram empregados na otimização do processo de extração. Dois processos distintos de secagem foram i
