CHAPTER 16 Drying 16.1. INTRODUCTION The drying of materials is often the final operation in a manufacturing process, carried out immediately prior to packaging or dispatch. Drying refers to the final removal of water, or another solute, and the operation often follows evaporation, filtration, or …
The countercurrent dryer is more effective and economical because the temperature difference between the drying gas and product stays relatively high throughout the drying process. The use of countercurrent dryers is restricted by the inflammability of the product and its behaviour at high temperatures. A countercurrent dryer is 20 to 30% ...

The co-current configuration needs a much higher initial temperature (4000° in this example) to heat the process material from its initial temperature and get the desired phase or chemical change, which in this example, occurs at 2000°.

Mostly Direct. Flow is co-current or countercurrent for cascade dryers. Flow is a combination of through the bed, cross, co-current or countercurrent for rotary louver. Residence time : Controllable. Residence time can be altered by varying the speed of rotation of the drum and the drum angle. Fill can be varied.

One critical factor in designing a rotary dryer that produces the desired end product characteristics is the air-flow configuration, or the direction in which the process gas flows through the dryer in relation to the material. Rotary dryers are available in two types of air-flow configurations: co-current and counter current. Both options have ...

BACKGROUND OF THE INVENTION This invention relates to an improved continuous grain flow, concurrent-countercurrent type grain dryer Grain, particularly corn, is ....
Sizing a Rotary Dryer using a Capacity Table. Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation concentrates, as well as chemical and industrial products. Frequently the saving of shipping weight so effected will pay for the dryer in a few months. Difficulties from freezing while in transit are also ...
This article presents both theoretical and experimental determination of the hydrodynamics of drying air in an industrial countercurrent spray dryer. Air velocity measurements were performed in selected areas of the tower to determine the flow pattern in the dryer and to collect data to validate the computational fluid dynamics (CFD) modeling ...
Louisville direct heat dryers are provided in counter-current dryer orientation when the application is warranted. With the counter-current or counterflow dryer, wet material is introduced into the drum on the opposite end that the hot gas enters the dryer and dry material discharges on the opposite end of the dryer as the exhaust vapor.

Air flow, countercurrent to product flow, is introduced in the upper portion of the Gala centrifugal dryer. This countercurrent airflow prevents moisture from escaping with the product and further reduces the surface moisture level. In many cases, a surface moisture of 500 ppm or less (0.05%)* can be achieved. Centrifugal Dryers 1/13/05 6:57 PM ...
current dryer was 4.0% for solids moisture, 1.3% for solids tempera- ture, and 1.8% for air temperature and for the countercurrent dryer it was 9.0% for the solids moisture, 2.0% for solids ...
Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those. For example, in a distillation column, the vapors ...
3. Counter-Current flow spray drying - definition and pros and cons. In counter-current spray drying, the material to dry and the air are injected at opposite location in the drying chamber - usually the material at the top of the chamber and the air at the bottom - which means that the dry air is contacting 1 st the particles which have been dried.
