CHAPTER 4 THERMODYNAMICAL‚ THERMOPHYSICAL‚ AND RHEOLOGICAL PROPERTIES OF FRUITS AND FRUIT PRODUCTS 4.1. INTRODUCTION Most processed and many freshly consumed fruits receive some type of heating or cooling during handling or manufacturing. Design and operation of processes involving heat transfer needs special attention due to heat sensitivity of fruits. Both theoretical and empirical relationships used when designing‚ or operating‚ heat processes need knowledge of the thermal properties

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

finite difference method in one dimensional system (slab). • It allows predicting temperature profiles. • The model will later be validated with experiments and data on apple fruit. ADVANTAGES OF MICROWAVE HEATING • Does not involve a conduction or convection medium • Food material is heated directly due to agitation of the polar molecules contained – namely water • Reduced drying time • Improved final quality of the dried products • Better rehydration DRAWBACKS OF MICROWAVE HEATING • Inherent

Throughout history‚ the United States and the U.S.S.R. have been competing in what is known as the "Space Race". This all began when the Russians sent the first satellite into space in 1958 called Sputnik. Soon after‚ Americans did the same. The U.S. followed in the footsteps of the U.S.S.R. with sending animals into space. When they sent the first human into space‚ Yuriy Gagaran‚ it became evident that the race to the moon had begun. In 1963‚ President John F. Kennedy made a speech saying "We

vapour lamp: It consists of a discharge envelope enclosed in an outer bulb of ordinary glass. The discharge envelope may be of hard glass or quartz. The space between the bulb is partially or completely evacuated to prevent heat loss by convection from the inner bulb. The outer bulb absorbs harmful ultra rays. The inner bulb contains argon and a certain quantity of mercury. In addition to two main electrodes a starting (auxiliary) electrode connected through a high resistance. The main electrodes
