How do you classify Drying Equipment?

Drying equipment also can be categorized according to the physical state of the feed such as wet solid, liquid, and slurry, and the type of heating system i.e. conduction, convection, radiation.

What is drying and its types?

Basically, drying can be done by two processes viz. natural drying and mechanical dehydration or artificial drying based on source of energy. Natural drying takes place under the influence of sunlight and wind and is of three types viz. sun, solar and shade drying.

What are drying systems?

In this system, mechanical dryers are used to remove water from wet grains by forcing either ambient air or heated air through the grain bulk. This is done through: Heated air drying - employs high temperatures for rapid drying.

What are the three drying methods?

A diverse range of equipment is used industrially for drying operations [42], including tray, screen-conveyor, screw-conveyor, rotary drum, tunnel, bin, tower, spray, fluidised bed, and flash driers. Some driers have a direct mode of heating, whereby air entering the drier is brought into contact with the wet solid.

What are the equipment and materials used in drying?

The most common are sun drying, hot air drying, contact drying, infrared drying, freeze-drying, fluidized bed drying, and dielectric drying. Depending on the nature of the products to be treated, either foodstuff or industrial material, these methods prove to be more or less adapted.

What are the types of drying?

What is a mechanical dryer? A mechanical way to remove the water from wet grains by blowing (heated) air through the grain. This drying is done until the grain has the desired moisture content.

What is mechanical dryer?

The purpose of drying is to retain the physico-chemical properties of materials, to ensure, in many cases, the preservation of materials over prolonged periods, and to eliminate excess weight in shipping.

What is the purpose of drying?

Drying removes moisture from meat products so that microorganisms cannot grow. Dry sausages, freeze-dried meats, and jerky products are all examples of dried meats capable of being stored at room temperature without rapid spoilage.

What is the example of drying?

What Does Air Drying Mean? This is the process of removing moisture from surfaces and coatings by using air (forced, dry or hot). Air drying prevents rusting and corrosion, which may be caused by redundant moisture. It is a principle used in the making of air-drying paints and coatings.

Which drying method is the best?

The dry matter of plant and animal material consists of all its constituents excluding water. The dry matter of food includes carbohydrates, fats, proteins, vitamins, minerals, and antioxidants (e.g., thiocyanate, anthocyanin, and quercetin).
