| The response of seeds to reduction in moisture content will determine whether they can be stored by conventional methods. The objective of this study was to verify the effect of desiccation on the germination and vigor of cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) K. Schum.) seeds, a tropical fruit species. The following seed moisture contents (SMC) were tested: 57.1%, 53.7%, 49.8%, 46.5%, 41.4%, 35.4%, 28.3%, 23.2%, 17.4%, 15.5% and 14.6%. Desiccation of seeds to as low as 41.4% (SMC) did not affect emergence, germination or vigor. However, reductions in speed of emergence were observed below 41.4%. When SMC was equal or lower than 35.4% a reduction in seed quality was observed. Loss of seed quality was increased when moisture content was equal... |

| O consumo de hortaliças desidratadas tem sido estimulado pela praticidade de uso, maior tempo de conservação comparado à in natura e possibilidade de aproveitamento da produção excedente, reduzindo efeitos de sazonalidade. A pesquisa propôs produzir uma farinha de beterraba com a aplicação de procedimentos tecnológicos simples e disponíveis para grande parte dos pequenos produtores. Foram comparados diferentes cortes de beterraba, longitudinais (long 2; 4,5; 9 mm) e transversais (trans 2; 4,5; 9 mm), quanto ao tempo de secagem e de trituração, taxa de secagem, rendimento em produto farináceo e sua granulometria. Considerando que a taxa de secagem foi baixa, que o tempo de permanência do produto no secador foi baixo, que a farinha apresentou baixa... |

| Este trabalho teve como objetivo avaliar a redução da temperatura nas partes externas de um secador de camada fixa para café, mediante diferentes combinações de tempo de revolvimento, utilizando-se termômetro sem contato. O experimento foi desenvolvido no mês de junho de 2004 em uma propriedade localizada em Jesuítas, Estado do Paraná. Foi utilizado café (Coffea arábica L.), variedade IAC 81. O secador utilizado foi o modelo de camada fixa, com câmara de secagem metálica, de formato cilíndrico, com um sistema de revolvimento de grãos adaptado. Observou-se que houve, em média, uma redução térmica de 156,7°C (79,1%) no sistema que vai da fornalha até a câmara de secagem. A combinação que proporcionou menor redução da temperatura foi a com ventilação... |

| The performance evaluation of a dual-function device for slicing and drying Okra developed at the Federal College of Agriculture, Ishiagu Nigeria was carried out and reported. The device was designed to slice and dry okra in one single-sequence operation. The physical characteristics of crop sample were investigated, characterised and processed in the device to determine their performance under steady state process conditions. The effects of the modified machine on crop processing were also investigated. The results shows that the mean equivalent diameters for each okra sample categorized as A, B and C are; 24. 54mm, 19.20mm and 15.79mm respectively. The slenderness ratios and sphericity determined for each of the three samples were; 3.04, 3.11, 2.79 and... |

| The study on osmotic pretreatment of oyster mushrooms was carried out in order to remove the moisture prior to further mechanical drying. Three salt concentration level (10, 15 and 20 g/100 g), two temperature levels of osmotic solution (30 and 45°C) and constant solution to mushroom ratio of 10 (w/v) were selected and the observations on water loss and solid gain were taken at an interval of 30 min up to 300 min. The osmotically pretreated samples were further dried up to its equilibrium moisture content in a tray drier at 60°C and experimental data were fitted successfully using Page and Henderson & Pabis model. The osmo-convective dehydrated samples were evaluated for its quality parameters i.e. color (L, a, b, ∆E, C* and h°), rehydration ratio... |

| Three commonly cited models for drying of agricultural products i.e. Page, Approximate form of diffusion, and Exponential were compared for their ability to the fit the experimental drying data of whole limes based on the root mean square error of estimate (RMSE) of the measured and simulated moisture contents. The comparison shows the Page model is the most suitable model having average RMSE = 0.046 wet-basis (decimal) while the Approximate form of diffusion and the Exponential models have 0.132 and 0.128 wet-basis (decimal), respectively. This indicated that the Approximate form of diffusion and the Exponential models both have less fitting ability then the Page model for the entire period (> 7 days) of drying in 30 tests at different... |

| In order to develop dried carrot pomace of high quality, experiments were conducted in completely randomized design (CRD). The carrot pomace was subjected to various blanching pretreatments i.e. water blanching (WB), steam blanching (SB), citric acid blanching (CB) and potassium metabisulphate (KMS) dipping after blanching (WBS). A control sample (untreated, UT) was kept for comparison. The samples were further dried by various drying methods i.e. convective drying (55°C and 65°C), sun drying and solar drying. The 65°C convective dried samples witnessed minimum drying time with higher fiber, total carotenoids, β-carotene content and minimum change in color parameters. Among the blanching pretreatments, the CB pretreatment showed better efficacy in... |

| Low shrinkage is an important parameter in marketing of dried lime fruits. An experiment conducted in order to evaluate affective factors on shrinkage coefficient of a dried lime fruit. Factors are defined as position of rest (vertical and horizontal), mechanical processing (length needling, width needling, slotting and intact or no processing), and temperature (shadow dried, sun dried, 40oC, 105oC and 200oC). Measured characters on a fruit were initial volume, final volume, and shrinkage coefficient. The average initial moisture content of limes was 476 % kg (kg db)-1. The position factor had no significant effect on shrinkage coefficient, but mechanical processing and temperature affected the final volume and consequently the shrinkage coefficient... |

| Lack of accurate information for the drying kinetics is the main barrier to optimize drying processes effectively. Online monitoring of drying data is not common due to practical issues involved in set-up application. In this study an imaging system was developed for large drying units to investigate the quality changes (color kinetics and shrinkage) combine with weight loss of food product spatially and non-destructively during convective drying. The imaging setup was used in a diagonal-airflow batch dryer and shifted along the dryer length to take data (food images and weight loss) at different positions using potato slices (5mm thick, 60°C) as drying material. First order model fitted well to value of ∆L* and ∆b* while ∆a* and ∆E fitted in zero order... |

| Biochar is considered as an option to ameliorate soil functions, by improving soil physical and hydraulic soil properties. This study investigated the effect of biochar and of wetting and drying cycles on the water infiltration at laboratory and at a hypothetical watershed scenario. In the laboratory, test samples with 2.5 and 5% (by dry mass) of a mango-wood biochar were added to a sandy and sandy loam soil material. Cumulative infiltration was determined after simulated intense wetting and drying cycles, by drying the samples at 30°C for three consecutive days. Additionally, biochar amended soil hydraulic parameters, obtained at the laboratory, were used to simulate the water discharge of a hypothetical watershed, with the Soil and Water Assessment Tool... |
