Mechanics of Agricultural Materials


Book Description

The importance of economical production of agricultural materials, especially crops and animal products serving as base materials for foodstuffs, and of their technological processing (mechanical operations, storage, handling etc.) is ever-increasing. During technological processes agricultural materials may be exposed to various mechanical, thermal, electrical, optical and acoustical (e.g. ultrasonic) effects. To ensure optimal design of such processes, the interactions between biological materials and the physical effects acting on them, as well as the general laws governing the same, must be known.The mechanics of agricultural materials, as a scientific discipline, is still being developed, and therefore has no exact methods as yet, in many cases. However, the methods developed so far can already be utilized successfully for designing and optimizing machines and technological processes.This present work is the first attempt to summarize the calculation methods developed in the main fields of agricultural mechanics, and to indicate the material laws involved on the basis of a unified approach, with all relevant physico-mechanical properties taken into account.The book deals with material properties, gives the necessary theoretical background for description of the mechanical behaviour of these materials including modern powerful calculation methods and finally discusses a large number of experimental results. Many of them can only be found in this book. Special attention is paid to the unified approach concerning theory and practice.The systematic treatment of the material makes the book useful to a wide circle of designers, researchers and students in the field of agricultural engineering. The book can also be used as a textbook at technical and agricultural universities.




Physical and Biological Properties of Agricultural Products


Book Description

The demand for agricultural production has been changing from quantitative stability to high qualitative standards. Especially in the first-growing Asian market, people now expect high standards in the quality of agricultural products, not cheap ones cultivated on a large scale any more. In this trend, it is important to maintain the safety and quality of agricultural products, which as organisms are also a challenge to handle as with other industrial products. This book offers comprehensive knowledge and technology to help assure and guarantee the high quality of agricultural products. The book analyzes and reviews product properties from physical and biochemical viewpoints, such as structure, dynamics, sound, electricity, and light. It also includes the design of processing machinery used in post-harvest operations, starting from harvest, preservation, processing, cooking, storage, to transportation and indispensable sorting techniques that include taste, smell, and freshness, notably the sweetness prediction of fruits with near infrared spectroscopy. This research study was developed in Japan, a leading country in the Asian market for high quality agricultural products, and it provides a full range of practical information for producing high quality agricultural products. The book covers comprehensive knowledge and technology applied to quality food preservation, as well as the safety and diversity in food. Contents include: Physical Properties of Agricultural Products * Structural Characteristics Related to Physical Properties * Fundamental Physical Properties * Thermal Properties * Mechanical Properties * Acoustic and Vibrational Properties * Electric Characteristics * Optical Properties * Biochemical Properties.




Thermal Properties of Food and Agricultural Materials


Book Description

This book discusses the methods for determination of data on thermal conductivity, thermal diffusivity, unit surface conductance or the heat transfer coefficient of foods and agricultural materials. It includes the applications of thermal properties in relation to cooling and thermal expansion.




High Pressure Processing of Food


Book Description

High pressure processing technology has been adopted worldwide at the industrial level to preserve a wide variety of food products without using heat or chemical preservatives. High Pressure Processing: Technology Principles and Applications will review the basic technology principles and process parameters that govern microbial safety and product quality, an essential requirement for industrial application. This book will be of interest to scientists in the food industry, in particular to those involved in the processing of products such as meat, fish, fruits, and vegetables. The book will be equally important to food microbiologists and processing specialists in both the government and food industry. Moreover, it will be a valuable reference for authorities involved in the import and export of high pressure treated food products. Finally, this update on the science and technology of high pressure processing will be helpful to all academic, industrial, local, and state educators in their educational efforts, as well as a great resource for graduate students interested in learning about state-of-the-art technology in food engineering.




Encyclopedia of Agrophysics


Book Description

This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

Physical Properties of Foods


Book Description

This book provides a fundamental understanding of physical properties of foods. It is the first textbook in this area and combines engineering concepts and physical chemistry. Basic definitions and principles of physical properties are discussed as well as the importance of physical properties in the food industry and measurement methods. In addition, recent studies in physical properties are summarized. The material presented is helpful for students to understand the relationship between physical and functional properties of raw, semi-finished, and processed food in order to obtain products with desired shelf-life and quality.










Theory, Determination and Control of Physical Properties of Food Materials


Book Description

In recent years, the importance of material science, or the understanding of the physical properties of food materials in the progress of food engineering, has become more recognized. Increasing numbers of basic and applied studies in this area appear in numerous journals and literature scattered around various disciplines. This 'Series in Food Material Science' is planned to survey, collect, organize, review and evaluate these studies. By doing so, it is hoped that this series will be instrumental in bringing about a better understanding of the physical properties of food materials, better communication among scientists, and rapid progress in food engineering, science and technology. This volume, Theory, Determination and Control of Physical Properties of Food Materia/s, Volume I of the 'Series in Food Material Science', contains basic principles, methods and instrumental methods for determination and application of the modifi cation of physical properties. In this book, noted investigators in the subjects have pooled their knowledge and made it available in a condensed form. Every chapter is selfcontained with most of them starting with a review or introduction, including the viewpoint of the author. These should offer a beginner a very general introduction to the subjects covered, make the scientists and technologists in the field aware of current progress and allow the specialists a chance to compare different viewpoints.
