Book excerpt: The objective of this research was to quantify and assess the energy use and efficiency of commercial cross-flow dryers when drying rice using a range of drying and ambient conditions. First, equations that predict the theoretical energy required to dry rice from any given initial moisture content to a desired final moisture content were developed for several rice cultivars using a semi-theoretical approach to obtain a basis for comparison to calculate energy efficiency. Theoretical energy requirements, expressed as the energy required per unit mass of water removed, increased exponentially as initial moisture content decreased. Additionally, medium-grains required more energy to be dried than long-grains; non-parboiled rice required more energy to be dried than parboiled rice. Second, a two-year study was performed to measure energy requirements of both an on-farm, cross-flow dryer and a commercial, cross-flow dryer. In 2011 for the on-farm dryer, energy requirements ranged from 2,840 to 5,310 kJ/kg water removed and in 2012 from 3,730 to 5,840 kJ/kg water removed. Energy efficiencies, which were calculated as the ratio of theoretical energy requirements to the measured energy requirements, ranged from 47 to 90% in 2011 and from 44 to 69% in 2012. Thermal energy requirements of the commercial dryer ranged from 6,900 to 9,670 kJ/kg water removed in 2011 and from 8,800 to 9,620 in 2012. Electrical energy use, which ranged from 300 to 400 kJ/kg water removed in 2011 and from 410 to 630 in 2012. Energy efficiency ranged from 26 to 36% in 2011 and from 27 to 29% in 2012. It was found for both dryers that thermal energy requirements were linearly correlated to the difference between drying air temperature and ambient temperature and linearly and inversely correlated to the amount of water removed per mass dry matter. Equations were developed to predict energy use and efficiency as a function of these two parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of Agriculture and Food Systems, Second Edition, Five Volume Set addresses important issues by examining topics of global agriculture and food systems that are key to understanding the challenges we face. Questions it addresses include: Will we be able to produce enough food to meet the increasing dietary needs and wants of the additional two billion people expected to inhabit our planet by 2050? Will we be able to meet the need for so much more food while simultaneously reducing adverse environmental effects of today’s agriculture practices? Will we be able to produce the additional food using less land and water than we use now? These are among the most important challenges that face our planet in the coming decades. The broad themes of food systems and people, agriculture and the environment, the science of agriculture, agricultural products, and agricultural production systems are covered in more than 200 separate chapters of this work. The book provides information that serves as the foundation for discussion of the food and environment challenges of the world. An international group of highly respected authors addresses these issues from a global perspective and provides the background, references, and linkages for further exploration of each of topics of this comprehensive work. Addresses important challenges of sustainability and efficiency from a global perspective. Takes a detailed look at the important issues affecting the agricultural and food industries today.

This book was released on 2018-03-17 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Costs of Commercial Drying, Storing, and Handling Rough Rice, 1965-66 As competition and rice handling and storage operating costs increase, efficiency becomes more important. If a commercial rice dryer Operator is to be competitive and provide low-cost services while earning a reasonable profit, he must maintain a high degree of operating efficiency. Detailed cost infor mation, by functions, provides a basis for operators to evaluate the impact on costs of such factors as type of storage facility, size or scale of operation, and variations in storage capacity utilized. Results of this study and others are combined into an analysis of the organization and operation of the rice industry. These data and analyses are applicable and useful to the rice industry. Changes since 1965 - 66 would not affect the usefulness of these cost relationships. Rice is normally harvested with moisture levels ranging from 18 to 26 percent. Since it cannot be safely held for long periods at these levels, the moisture content is generally reduced to about 12 to 14 percent before storing. At commercial dryers, this is accomplished artificially by use of aeration and heat. Although much of the moisture can be removed by aeration alone, use of heated air greatly reduces drying time, making it possible to handle larger volumes of rice in shorter periods. As with most other crops, average length of the rice harvesting season has declined in recent years. Thus, the bulk of green paddy rice is now harvested within 4 to 6 weeks. Handling rates at commercial dryers, which provide both drying and storing facilities, must be geared to harvesting rates to compete effectively. Commercial rice dryers have attempted to keep pace with the rapid advances in harvesting technology through the adoption of better equipment and improved operating practices.
