Dehydration is the key to food preservation reducing volume and increasing shelf life Dehydration technology has witnessed renaissance with the development of advanced technology such as microwave drying freeze drying fluidized bed drying and refractance window drying Combination of drying methods has increased the versatility of dehydration process of
There are a large number of dryer designs and the characteristics of different types of drying equipment and their applications are summarised in Table of commercial drying operations are given by Greensmith 1998 The relative costs of different drying methods from data by Sapakie and Renshaw 1984 are as follows forced air drying 198; fluidised bed
Drying equipmen t is widely used in chemical pharmaceutical agricultural and forestry products food light industry and other fields It is a general purpose mechanical product with a large quantity The drying equipment industry has gone through many years of history from formation and development to maturity
DRYING PRINCIPLE IN FOOD The process of drying food involves the process of changing the form of water in food to gas Then remove it from the f ood so that it becomes dehydrated
Principle FBD works on the fluidization principle A high pressure Hot air from the supply is passed through the perforated container containing wet granules As the hot air passes through container granules start to suspend in the air to become dry called a fluidized state the process is called fluidization FBD Diagram

The physical and engineering principles of drying are discussed by Mujumdar and Menon The process calculations used in the design and operation of industrial dryers are reviewed by Pakowski and Mujumdar Psychrometric Calculations The properties of air/water vapor mixtures are of fundamental importance to calculations of air drying processes
Freeze drying is an extreme form of vacuum drying in which the water or other solvent is frozen and drying takes place by subliming the solid phase Freeze drying is extensively used in two situations 1 when high rates of decomposition occur during normal drying; and 2 with substances that can be dried at higher temperatures and that are
Under less favourable conditions threshed seed needs further drying Principle of seed drying The migration of moisture to the surface is slower than the evaporation and a moisture gradient is developed in the kernel Elimination of moisture from the seed depends upon the relative humidity and temperature of the environment surrounding the seed
There are a large number of dryer designs and the characteristics of different types of drying equipment and their applications are summarised in Table of commercial drying operations are given by Greensmith 1998 The relative costs of different drying methods from data by Sapakie and Renshaw 1984 are as follows forced air drying 198; fluidised bed
The effect of oven drying OD at 50±5°C sun drying SD and fresh leaves control of seven selected herbs used in herbal preparation as herbal baths were evaluated
This chapter provides an in depth review of spray drying technology and its application to the formulation of poorly water soluble drugs In the early part of the chapter the fundamentals of the process are discussed including process theory process components equipment options equipment by scale various feeds and typical solvent systems
5 Many tools and equipment driven by compressed air cannot withstand water or mois ture Many processes using compressed air are processing products which cannot • As third method chemical drying is often used the moisture is removed by ab sorption or adsorption in a certain substance With absorption the moisture is cap
Functions of Stenter Machine However the stenter is the only drying machine that provides adjustment and control of fabric width during drying In addition to drying the stenter performs several other functions namely Imparting a particular mechanical finish affecting appearance and feel commonly known as stenter finish
That means a lyophilizer will have systems of refrigeration vacuum heating drying chamber vapor collect condenser and controller as well as the auxiliary components like temperature probes vacuum sensors software and so on Working Principle of Lyophilization Lyophilization is based on a simple principle of physics called
