In recent years, the technology of cryogenic comminution has been widely applied in the field of chemical engineering, food making, medicine production, and particularly in recycling of waste materials. Because of the increasing pollution of waste tires and the shortage of raw rubber resource, the recycling process for waste rubber products has become important and commercially viable. This technology has shown a great number of advantages such as causing no environmental pollution, requiring low energy consumption and producing high quality products. Hence, the normal crusher which was used to reclaim materials, such as waste tires, nylon, plastic and many polymer materials at atmospheric 12 temperature is being replaced by a cryogenic crusher. • In the cryogenic crusher, the property of the milled material is usually very sensitive to temperature change. When a crusher is in operation, it will generate a great deal of heat that causes the material temperature increased. Once the temperature increases over the vitrification temperature, the material property will change and lose the brittle behavior causing the energy consumption to rise sharply. Consequently, the comminution process cannot be continued. Therefore, it is believed that the cryogenic crusher is the most critical component in the cryogenic comminution system. The research on the temperature increase and energy consumption in the cryogenic crusher is not only to reduce the energy consumption of the crasher, but also to reduce the energy consumption of the cryogenic system.
Drawing on the expertise of the University of California's Postharvest Technology Center, this publication discusses commercial uses of modified- or controlled-atmosphere technology which can be used during transport, temporary storage, or long-term storage of horticultural commodities destined for the fresh market or processing. In modified atmospheres and controlled atmospheres, gases are removed or added to create an atmospheric composition around a commodity that is different from that of air. Modified- or controlled-atmosphere technology can be used during transport, temporary storage, or long-term storage of horticultural commodities destined for the fresh market or processing. Chapter 1 discusses how modified- or controlled-atmosphere technology can be used during transport, temporary storage, or long-term storage of horticultural commodities destined for the fresh market or processing. Chapter 2 discusses the ways biologically important gases are sampled, analyzed, and mixed. Since the rate of respiration of plant tissue is tightly coupled to its overall metabolic rate-and often inversely proportional to shelf life-the measurement and control of respiration are of vital interest in devising strategies to maintain quality after harvest. Chapter 3 discusses the role of Ethylene in the postharvest life of many horticultural crops. Sometimes this role is beneficial (promoting faster and more uniform ripening before retail distribution) and sometimes it is deleterious (speeding senescence and reducing shelf life). This chapter addresses the properties of this gas and ways to both harness its beneficial effects and avoid undesirable results during the postharvest handling of perishable commodities.
Taking greater advantage of powerful computing capabilities over the last several years, the development of fundamental information and new models has led to major advances in nearly every aspect of chemical engineering. Albright’s Chemical Engineering Handbook represents a reliable source of updated methods, applications, and fundamental concepts that will continue to play a significant role in driving new research and improving plant design and operations. Well-rounded, concise, and practical by design, this handbook collects valuable insight from an exceptional diversity of leaders in their respective specialties. Each chapter provides a clear review of basic information, case examples, and references to additional, more in-depth information. They explain essential principles, calculations, and issues relating to topics including reaction engineering, process control and design, waste disposal, and electrochemical and biochemical engineering. The final chapters cover aspects of patents and intellectual property, practical communication, and ethical considerations that are most relevant to engineers. From fundamentals to plant operations, Albright’s Chemical Engineering Handbook offers a thorough, yet succinct guide to day-to-day methods and calculations used in chemical engineering applications. This handbook will serve the needs of practicing professionals as well as students preparing to enter the field.
