Abstract: New technologies and tools have being developed from the needs arising during process, which require power, precision and/or replications, everything to simplify as well as to facilitate these operations. During the development of alternative process for water treatment based on the application of Moringa oleifera seeds, it has been observed the need of developing a new method that simplifies the seeds processing for further application as natural coagulant. This way the introduction and application of the proposed alternative treatment would be considerably simplified. The aim of this research work was identified as to develop equipment to process the moringa seeds, removing the seeds shells. Initially, a detailed study of pods and seeds optical as well as mechanical properties was carried out, aiming to survey basic parameters to develop the proposed processing equipment. In parallel, it was also carried a research on shelling mechanisms as disclosed by the pertinent literature, aiming to select operating mechanisms suitable to this project. Finally it was developed the equipment project by means of software simulations and further construction of a prototype for real tests. Seeds physical characterization tests included 4 different seed development stages. As result, it was observed no significant difference of fat and protein contents. It was just observed variations in the color and moisture contents. Following, a correlation between moisture content and Moment of Inertia, obtained through the Biospeckle technique has been carried as well. These results and the evaluated parameters did not give support to make the correlation of Moment of Inertia with seed developing stage. The mechanical characterization revealed higher stress concentration on the seed edges for the four seed development stages. In that situation, shell breakup did not commit of internal portion of the seeds. The equipment idealization for seeds shelling included 3 different options. However all of them induced compressive as well as shear stress loadings. The shelling equipment options included: eccentric table, cylinders and parallel discs. The final decision was based on all advantages and inconveniences of each mechanism, after which the concentric table was selected. Despite the elected mechanism did not offer the easier construction, it was understood it was the one allowing the easier automation and control Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Dal Fabbro, Inacio Maria, 1944- (advisor), Fabbro, Inacio Maria Dal, 1944- (advisor), Paterniani, José Euclides Stipp, 1957- (coadvisor), Universidade Estadual de Campinas.

Abstract: Optical techniques have been used for both technical and scientific purposes. Optical techniques are usually characterized as being robust, inexpensive, non-invasive and non-destructive methods in to evaluate a diversity of materials which include agricultural derived products. It also shows applications ranging from engineering to human and animal health. In this doctoral dissertation, a new technique to evaluate some fruit properties is proposed. It combines two optical techniques (i.e. Biospeckle and Scan-line laser) whose applicability has been demonstrated as being alternative and innovative. The new proposed technique allows low-cost data acquisition, automation of the entire process, and a proper selection and classification method of vegetable bodies (e.g. fruits). Biospeckle allows obtaining information regarding the quality level of biological material into cellular structures. Scan-line laser enables the attainment of the object geometry on the axes Xi (i=1,2,3). The main purpose of this doctoral dissertation is to obtain a digital survey of biological materials (i.e. papaya, pear and tomato) integrating both geometric positioning and information concerning to its biological activity. The differentiation between different fruit shapes, fruit sorting by size, class, color and defects through image processing was also carried out. Thus it was also possible to observe fruits with surface irregularities, maturity, and mechanical damage, among others. This is the basis proposed for the automatic selection of agricultural products. The following materials were employed in the tests: a line-emitting diode laser with a wavelength of 632 nm, diffuse white light, CCD camera, computer, optical table, papaya, pear and tomato fruits and polystyrene spheres. The softwares utilized were: ImageJ, Octave, Matlab. A total of five computer programs were developed for the image processing procedures. Five experiments were performed: (1) Maturity Assessment of Fruits; (2) Three Dimensional Reconstruction and Mapping of Bioactivity; (3) Miscellaneous Format Detection; (4) Mapping Format, Class and Coloration; (5) Defect Detection. In Maturity Assessment there were correlated traditional methods to verify the maturity (the Hunter parameters L a b, pH, Total Soluble Solids (TSS), the relationship between Total Soluble Solids and Titratable Acidity (TSS/TA), Modulus of Elasticity, weight and diameter) and the optical technique Biospeckle by calculating the Moment of Inertia (MI). For the Three Dimensional Reconstruction the fruits were rotated by a stepper motor. At every step of the motor, the fruit was illuminated by the projected laser line and photographed in order to obtain both geometric and biospeckle data by the LASCA (Laser Speckle Contrast Analysis) method. The correlation between traditional methods for the maturity assessment and values of MI was analyzed. This doctoral dissertation shows that it is possible to evaluate the maturity of fruits through Biospeckle. A three-dimensional map that includes… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Dal Fabbro, Inacio Maria, 1944- (advisor), Fabbro, Inacio Maria Dal, 1944- (advisor), Enes, Adilson Machado (coadvisor), Universidade Estadual de Campinas.
