2. Desidratação parcial de tomate cereja em secador de bandejas vibradas com reciclo
In this essay, it has been analyzed the partial dehydration of oval cherry tomato Lycopersicum sp. Mill, by using a vibrated tray dryer with recycle until the tomatoes reached 15% of its initial water content what represents 70,19% of humidity in wet basis or 2,35 kg of water/kg of dry mass in dry basis. The dryer used consists basically of a vertical dryer

3. Evaluation of alternative ingredients in diets of broilers with the addition of enzymes / Avaliação de ingredientes alternativos na alimentação de frangos de corte com a adição de enzimas
Two experiments were conduced to evaluate the inclusion of alternative ingredients, sunflower meal and sorghum, in diet of broilers with the addition of enzymes. The experiments were divided into three independent trials, which corresponded to each phase of raising: initial phase (1 21 days), where the performance characteristics were evaluated; growing phas

4. Avaliação do processo de obtenção de farinha da casca de banana (Musa sapientum) das variedades Prata, Pacovan e Maçã / Process evaluation to produce banana (Musa sapientum) flour from peels of fresh fruit varieties Prata, Pacovan and Apple.
This work aimed to study the drying process of banana (Musa sapientum) peels (varieties Prata, Pacovan and Apple). The convective drying was performed at various air temperatures (40C to 60C) and at an average air speed of 1.0 m/s. It was used a fixed bed dryer with upward flow of air. The tests were conducted until the sample reached equilibrium between its

5. Contribuições ao estudo da fluidodinâmica e da secagem de pastas em leitos fluidizado e vibrofluidizado
The aim of this study was to analyze the fluid dynamic of the fluidized and vibrofluidized beds with particles with diameter under 1.00 mm, and also to analyze the fluid dynamic behavior of wet beds and the drying of different liquids and suspensions during the transient drying period. The purpose of these tests is to obtain relevant information about the in

6. Experimental study of fluidized bed agglomeration of acerola powder
The aim of this work was to study the main effects of acerola powder on fluidized bed agglomeration. A 2(4-1) fractional factoring design was used to evaluate the main operating conditions (fluidizing air temperature, fluidizing air velocity, atomizing air flow and height of nozzle in the bed). The mechanical and physicochemical product changes were determin

7. Caracterizacao fisica, secagem (fritura de imersao e leito fixo) e isoterma de dessorcao do bagaco de cana / Physical characterization, Drying (Immersion Frying and bed fixed) and Desorption isotherm of the sugar cane bagasse
This work objectified characterize the bagasse of sugar cane from two sugar-alcohol-industry; obtained drying kinetic curves of the bagasse in two different methods: cross flow in bed fixed and drying of immersion frying; obtained desorption of isotherm of the sugar cane bagasse. The characterization of the bagasse was made through grain sized analyses with

8. Metodologia numérica para análise de secagem de grãos em leito fixo pela primeira e segunda Lei da Termodinâmica / Numerical methodology for analyzing deep bed grain drying by first and second laws of Thermodynamics
This work presents a methodology for analyzing deep bed grain dryers by means of the first and second laws of thermodynamics. The thermodynamic modeling is a more complex extension of a literature-available thermodynamic modeling of fluidized bed dryers, which involves a system of lumped mass and energy equations. Thus, the present analysis involved a system

9. Qualidade fisiológica e pré-condicionamento de sementes de cultivares de soja de diferentes grupos de maturidade em três épocas de colheita / Physiologic quality and pre-conditioning of soybean seeds cultivars with different maturity groups in three harvesting times
The use of quality seeds in soybean plantations is fundamental to guarantee fast and appropriate establishment of the stand. The objective of this work was to evaluate the physiologic quality of soybean seeds harvested in three times and submitted to the osmotic conditioning. Seeds of the soybean cultivars with different maturity groups: Confiança (semi-pre

10. Biofilter efficiencies in the purification and deodorization of hydrogen sulfide emissions / Desempenho de filtro biológico na depuração e desodorização de emissões de sulfeto de hidrogênio
Traditionally the industrial waste gases have been treated by physical-chemical processes, such as scrubbers, absorption, condensation and oxidation. Although these techniques presented great efficiency, the need to add chemical products and the replacement of adsorbent results in relatively high operational costs compared to biological treatment techniques.

11. Aproveitamento biotecnológico de resíduos agroindustriais na produção de glucoamilase
The Alto Vale do Itajaí region is a big producer of cassava flour for starch. The processing of the cassava flour generates residues which are usually disposed in the environment in an inadequate way, leading to an environmental impact. This way, the biotechnology proves itself to be an interesting alternative in transforming these residues, which still con

12. Efeitos das condições de armazenagem sobre a qualidade da soja (Glycine max (L.) Merrill) e do óleo bruto / Effects of storage conditions on the quality of soybean grains (Glycine max (L.) Merrill) and crude oil
Brazil s 2005/06-grain production is forecast at approximately 123 million tons. Of this total, Brazil should produce 57 million tons of soybean grains, i.e., 46% of the national production. Brazilian agricultural production, however, needs to meet the international demands in order to gain foreign markets, maintaining good quality of grains is therefore ess
