1. Lescano, Cesar Augusto Agurto. 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.

Degree: 2009, Universidade Estadual de Campinas

Abstract: 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 production. Drying is an operation that could make this residue viable. The drying is a technology widely used by the industries to improve the quality and extend the shelf-life of the products due the decrease of the degraded reactions. Another result of a drying process is the decrease of the product's weigh and size, facilitating its transport and storage. However, until now, despite the technologic overhauls in the chemical and food industries, problems persist on defining the specific appropriate methods to dry different biological materials, mainly those used as human food. The soy milk residue is rich in proteins, fibers and vitamins, what makes it important in decreasing the enormous protein deficit of the world population, beyond the possibility of elaborating new products using Okara as ingredient, thus giving aggregate value to these new products. Okara is a very moist particulate material, 80% (b.u.), with high content of superficial moisture. A mechanic pressing operation before drying is indicated to decrease the Okara initial moisture content to around 60% (b.u.) and in this way optimize the drying process, without non-necessaries energy losses. The Okara is a thermo-sensible material and, while wet, highly deteriorative. After pressing, this material is particulate, highly cohesive, hard flowing, porous and with highly internal moist content (being not possible to be characterized as a paste). The objective of this research is the analysis of the soy milk residue drying using three types of dryers: conventional spouted bed dryer, rotary cylindrical dryer assisted by microwaves and microwave oven drier. The drying in the spouted bed was made in batch process while, in the rotary cylindrical dryer with application of microwaves it was conducted continuously. The use of inert material inside the dryer was necessary in both cases: in the spouted bed dryer, the inert that showed better fluid-dynamic with the Okara was the polypropylene, while in the rotary dryer the inert that showed better transport monitoring of Okara particles was the polystyrene. The same procedure was followed to prepare the Okara for both equipments. The variables analyzed in the spouted bed dryer were: drying air temperature, ratio between the air flow rate and minimum spout flow rate and time of material shredding; in the rotary cylindrical dryer assisted by microwaves, the independent variables were: drying air temperature and flow rate and microwave power. For both dryers, an experimental factorial design, 2³, was applied and the responses analyzed were: Okara moisture content for a fixed drying time and parameters of Page model for the drying kinetics (the last for the… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Rocha, Sandra Cristina dos Santos, 1957- (advisor), Marsaioli Junior, Antonio, 1937- (coadvisor), Universidade Estadual de Campinas.

2. Vieira, Melissa Gurgel Adeodato, 1979-. Analise da secagem de polpa de celulose para a obtenção de papel reciclado tipo cartão: Analysis of cellulose pulp dryng for the production of card type recycled paper.

Degree: 2006, Universidade Estadual de Campinas

Abstract: Even though the great technological advances, the paper still carries out an important role in the culture and in the diffusion of information. Although it is produced by a renewable source, as the wood, technology allowing paper reuse is available. A selective pick up is necessary for the pulp processing from recovered fibers. The paper recycling allows a great reduction of the amount of urban solid residues, avoiding the use of natural sources as wood and water, besides decreasing a lot the energy consumption in the paper industry. The production of the cellulose pulp is the first great energy consumer in the process of paper production, followed by the paper drying process. The drying is a complex process, of great importance, not only in energy terms, but for the quality of the final product. In this context, this work had the objective to analyze the drying of cellulose pulp made from recovered fibers for the production of card type recycled paper. For this, a convective dryer was projected, in laboratorial scale, for the drying of the paper pulp. The drying curves as a function of different operating conditions were analyzed and the paper dessorption isotherms were determined by the dynamic method. An analysis of the product quality was accomplished for different conditions, as well as the process energy consumption evaluation. A comparative study between the natural drying (used in small productions) and the drying by forced convection was also effectuated. To complement the drying analysis, the shrinkage of the paper was evaluated during the drying and related to the operating conditions, physical characteristics and quality of the product. The dryer developed in this work showed to be appropriate for the drying of the recycled card type paper , presenting energy efficiency compatible with dryers used in paper industries (24,53%). It was verified that the increase of the temperature and velocity of the drying air influenced the process reducing the drying time. However, the quality of the paper is poor for severe operating conditions, leading to a less uniform final product, having a very dry surface. In the paper shrinkage study during drying, as well as in the analysis of the surface quality, similar results were gotten for the papers dried at 70 and 80°C. Significant modifications of structural properties and a low quality of the product were verified for the paper dried at 90°C, indicating a limit to the air temperature for the convective drying of the analyzed recycled papeI. The paper dried at 90°C suffered 15% of surface shrinkage and also 40% of linear and volume reduction during the falling rate drying phase. The paper dried under softer operating conditions (66°C; O,22m/s) presented characteristics similar to the paper naturally dried. Thus, a type card recycled paper can be producted with adequate quality using the convective drier, reducing significantly the necessary time for the drying af the paper sheet Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Rocha, Sandra Cristina dos Santos, 1957- (advisor), Universidade Estadual de Campinas.
