25. Sizing procedure of solar heating systems for agricultural products drying / Metodologia de dimensionamento de sistemas de aquecimento solar para secagem de produtos agricolas
A solar collector design procedure was proposed for sizing solar assisted crop-drying systems using empiric correlations, previously found, to determine the solar fraction supplied by the system. A case study of an in-bin crop drying was accomplished in the city of Campinas - SP with pre-heating of the air through a solar collector complemented by convention

26. Study for the aggregation of value to the cashew products: fruit and chestnut in bars formularizations elaborations. / Estudo para a agregação de valor aos produtos de caju : elaboração de formulações de fruta e castanha em barras.
The aim of this research was to contribute to reduction of cashew apple losses, estimated at 1 billion kg/year. Vacuum osmotic dehydration of the cashew apple clone CCP 76 was done using clarified cashew juice concentrated to 65oBrix as the osmotic agent. Response Surface Methodology was used to define the best time temperature combinations: 40°C/100min and

27. Estudo Comparativo de SuperfÃcies Seletivas para Coletores Solares / Comparative Study of Selective Surfaces for Solar Collectors
In practical applications of active and passive solar energy, or other construction purposes, the coating material which absorbs solar radiation has an important role as regards the absorption and emission of thermal radiation and, directly influencing the cost benefit the product. Surface coatings for solar radiation-absorbing plate or selective surfaces, c

28. Secagem interminente com fluxo cruzado e altas temperaturas e sua influencia na qualidade do trigo duro (Triticum durum L.)
Product quality depend on the processing methods used and also on the end use of the product. Of alI commomly used processes drying is one of the most important steps to assure grain quality. The objective of this work was to verify the influence of intermittent cross flow drying and high temperatures on IACI002 durum wheat (Triticum durum L.) final quality.

29. Estudo do dimensionamento de coletor solar e secador
This research work reports the study of a system of a solar collector and a bin for grain drying. It was developed mathematical simulations to present the transient and steady state phenomena applied to two kinds of plane solar collectors. The first type of solar collector was covered with plastic sheet and the second kind had the absorbent plate directly ex

30. Caracterização e avaliação do subproduto da industria de gelatina soluvel
The objective of this study was to evaluate the chemical composition of the solid by-product. of soluble gelatin manufacture, as well as to investigate the possibility of utilizing such residue as a proteinaceous ingredient in animal feedstuff. When fresh the residue had about 90% moisture. After drying either in an electric oven or in a solar distill at 70

31. Construction and evaluation of a collector storage of solar energy, unconventional, for heating air in the drying of agricultural products / Construção e avaliação de um coletor armazenador de energia solar, não convencional, para aquecimento de ar na secagem de produtos agricolas
Construiu-se, com materiais de baixo custo e facilmente encontrados no mercado, tais como I tijolos, pedra britada, madeira e plástico, um coletor solar de 60 m2(3 m de largura por 20 m de comprimento), contendo um leito de pedras capaz de funcionar como armazenador de energia. O coletor solar foi empregado para aquecer o ar ambiente que, por sua vez, foi u
