This paper presents the drying characteristics of rice husk and cornstalk with high moisture content at fixed temperatures. Experiments were performed in an oven drier, to reveal to the effects of initial moisture content, bed thickness and drying temperature on the biomass drying characteristics. The results indicated that the drying time was decreased as the rising of the drying temperature, and increased along with the initial moisture content and bed thickness. Moreover, the risk husk was easy to be dried than the cornstalk.

John Deere and Frugal Moisture meter were compared with that of Indosaw standard. Frugal moisture meter was similar to the Indosaw standard but John Deere moisture meter were, on average, 2% higher than the standard. It is believed the John Deere model can be recalibrated to provide accurate results. Baseline survey on mycotoxins among 200 households of two districts of Bangladesh through the questionnaire indicate that the farmers were familiar with grain discoloration due to mold contamination but they did not have any idea about mycotoxins production on grains. Grain samples, one kg from each of 200 households were collected during May and June (Boro 2015), 119 had moisture content >14% and 37 had moisture content >20%. Purity, discoloration, mold invasion, insects and germination were assessed in the laboratory. Inert matter was 10% in 142 samples and >15% in 15 samples. Molds were associated with grain discoloration. Samples with high moisture content had higher quantity of moldy grains and stored pests. There was 25% grain discoloration of which 18% were moldy when the moisture content was >20%. Blotter incubation test revealed 19% incidence of Aspergillus growth on the 19% of the grains and Fusarium growth in 9% of the grains and produce Aflatoxins produced by Aspergillis and fumonisins by Fusarium were detected in rough rice of India (Reddy et al., 1986). Detection and quantification has of these two mycotoxins have not yet been done in Bangladesh. Through the present study the paddy samples will be analyzed by USDA Romer Lab test kit strips to create a national database on mycotoxins in paddy of Bangladesh.J. Bangladesh Agril.

Objetivou-se, com o presente trabalho, propor um novo método de processamento e secagem, assim como avaliar o comportamento dos grãos submetidos a este processo, por meio da taxa de redução de água e do ajuste de diferentes modelos matemáticos aos dados experimentais da secagem. Os frutos colhidos no estágio maduro foram divididos em três lotes. O primeiro foi seco continuamente à temperatura de 40±1 °C. O segundo consiste na secagem do café natural até os teores de água de 0,56±0,02, 0,41±0,02, 0,28±0,02 e 0,20±0,02 decimal (base seca, b.s.), seguido de beneficiamento e secagem contínua nas temperaturas de 35±1 ºC e 40±1 ºC. O terceiro lote correspondeu à secagem contínua do café descascado e desmucilado na temperatura de 40±1 °C. Em todos os lotes, a secagem foi encerrada quando os grãos atingiram o teor de água de 0,12±0,05 (b.s.). Aos dados experimentais da secagem foram ajustados dez modelos matemáticos utilizados para representação da secagem dos produtos agrícolas. Além da representação da cinética de secagem foi avaliada a taxa de redução de água dos grãos. Conclui-se que a taxa de redução de água é maior para a temperatura de secagem de 40±1 °C, especialmente para maiores teores de água. O tempo total de secagem do café beneficiado com alto teor de água é expressivamente reduzido, quando comparado ao tempo de secagem completa do café natural. O modelo de Midilli descreve satisfatoriamente a cinética de secagem do café beneficiado.

AbstractDuring 1984–1997, the ferronickel plant in Drenas used iron-nickel ore from the mines of the Republic of Kosovo: Glavica and Çikatove (Dushkaje and Suke) mines. However, during the years 2007–2017, when the plant started operating from the cessation of production, which was from 1998 to 2007, some types of iron-nickel ores from different countries began to be used, starting from iron-nickel ores from Kosovo, iron-nickel ores from Albania, ores from Indonesia, ores from the Philippines, ores from Guatemala, ores from Turkey and ores from Macedonia. The ore composition, however, is mainly oxide-laterite ore. Iron-nickel ores in the plant are characterised by high moisture content, a very important factor influencing the process of scraping the charge in rotary kilns and presenting in general. Among the iron-nickel ore used in the ferronickel plant, the ores from Albania are characterised due to their low moisture content when compared with the other ores as well as the high content of iron oxides, which affect the temperature rise inside the furnaces, as the iron ores play an important role in the pre-casting process in rotary kilns.

In a fungal suryey of sawn timbers in scattared localities in Benin City, fungal species isolated were mainly members of <i>Hyphomycetes</i>, with few <i>Ascomycetes</i> and<i> Basidiomycetes</i>. Cellulolytic abilities of isolates were determined and found to be highest in a basidiomycete, <i>Pleurotus ostreatus</i>. The high incidence of these isolates was traced to the poor ventillation in the shades where the timbers arę sold and the high moisture content of timber before display for sale.
