1. STATIC PRESSURE DROP IN LAYERS OF CASTOR BEAN GRAINS
ABSTRACT Knowledge regarding the static pressure drop in granular layers is of fundamental importance in the development of efficient drying and aeration projects of agricultural products. Thus, the objective of this study was to evaluate the effects of impurity contents on the static pressure drop in different bed depth of castor bean grains, as well as mod

2. LIQUID DIFFUSION DURING DRYING OF SORGHUM GRAINS UNDER DIFFERENT CONDITIONS
ABSTRACT Drying is the most widely used process to ensure the quality and stability of plant products. Therefore, this study aimed to determine the effective water diffusivity and activation energy in grain sorghum during drying at different temperatures and initial moisture contents. Sorghum grains (cultivar DeKalb 640) were harvested with an initial moistu

3. PRICE AND QUALITY OF COFFEE (COFFEA ARABICA L.) DRIED USING AIR DEHUMIDIFIED BY CONVECTION
ABSTRACT Grain drying processes have been improved to reduce costs and losses of coffee beverage quality. The objectives of this study were to evaluate the quality of coffee dried using air partially dehumidified before entering drying units (DUs) in four coffee-producing farms, as well as the effects of such process on coffee commercial value. The method co

4. Immediate and latent effects of drying soybeans with dehydrated air
ABSTRACT. New grain drying techniques have been improved to reduce post-harvest losses. The electric air dehumidifier (UTA 60®) is an example; it was installed at the ELLITT Seed Company for drying soybean seeds (TEC 7849) with random sample collection (DIC). Our objective was to evaluate the immediate and latent effects of the dehumidified air on the vigou

5. Infrared radiation drying of Moringa oleifera grains for use in water treatment
RESUMO Este estudo teve como objetivo avaliar os efeitos da utilização da radiação infravermelha na secagem convectiva de grãos de Moringa oleifera sobre a temperatura no secador e no grão, consumo de energia e qualidade dos grãos. Um experimento no esquema fatorial foi conduzido em 2013 para determinar os valores ótimos da temperatura do ar (30 a 58

6. EFFECT OF DRYING METHODS ON CRAMBE (Crambe abyssinica HOCHST) SEED COAT PIGMENTATION AND ON OIL AND BIODIESEL QUALITY
ABSTRACT The objective of this study was to evaluate the effect of different drying methods on seed coat pigmentation and quality of oil and biodiesel extracted from crambe. The experimental design was completely randomized with five treatments and four replications, totaling 20 plots. The treatments consisted of drying with heated air, natural air, ground,

7. Effects of drying air temperature and grain initial moisture content on soybean quality (Glycine Max (L.) Merrill)
ABSTRACT This study aimed to evaluate the effect of air-drying temperature and initial moisture content on volume shrinkage, physical quality and oil extraction yield of soybean grains. The grains used in this experiment were harvested at two distinct moisture levels of 19 and 25%. Then, these grains were taken to dryness at three different air temperatures

8. Retrogradation of heat-gelatinized rice grain in sealed packaging: investigation of moisture relocation
Abstract The aggregation of water molecules inside heat-gelatinized rice grain due to retrogradation of the grain was investigated by textural change and scanning electron microscopy (SEM) analysis of cooked grains after storage at 11 °C in a sealed package. Relaxation tests using a disc-type tip showed an increase in hardness (strength) of the cooked grain

9. Yield-scaled global warming potential of two irrigation management systems in a highly productive rice system
ABSTRACT Water management impacts both methane (CH4) and nitrous oxide (N2O) emissions from rice paddy fields. Although controlled irrigation is one of the most important tools for reducing CH4emission in rice production systems it can also increase N2O emissions and reduce crop yields. Over three years, CH4 and N2O emissions were measured in a rice field in

10. Modificação enzimática da farinha de grãos quebrados de arroz para produção de alimento sem glúten / Enzymatic modification of grain flour broken rice to produce food without gluten
O arroz (Oryza sativa L.) é um cereal consumido em todo o mundo, sendo a base energética da alimentação humana, constituindo cerca de 23% das calorias diárias totais e cerca de 14% das proteínas. Os grãos quebrados de arroz são subprodutos gerados na indústria processadora de arroz durante o beneficiamento do cereal e tem sido utilizados para produ�

11. Numerical study on hygroscopic material drying in packed bed
The paper addresses numerical simulation for the case of convective drying of hygroscopic material in a packed bed, analyzing agreement between the simulated and the corresponding experimental results. In the simulation model of unsteady simultaneous one-dimensional heat and mass transfer between gas phase and dried material, it is assumed that the gas-solid
