What is pharmaceutical spray drying?

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals, or materials which may require extremely consistent, fine, particle size.

Which product is dried by spray dryer?

Spray drying is the process in which liquid is transformed into dried particles by spraying the feed into hot drying medium. The feed can either be a solution, suspension or paste. It is generally used to prepare milk, coffee and fruit juice powder.

What is spray drying technology?

Spray-drying is a rapid, continuous, cost-effective, reproducible and scalable process for the production of dry powders from a fluid material by atomization through an atomizer into a hot drying gas medium, usually air.

What is drying process in pharmaceutical industry?

Drying is the process of removing the presence of solvents (i.e. water or other liquids) in a formulation with the presence of heat. All drying processes of relevance to pharmaceutical manufacturing involve evaporation or sublimation of the liquid phase and the removal of the subsequent vapour.

What are the two types of drying?

Basically, drying can be done by two processes viz. natural drying and mechanical dehydration or artificial drying based on source of energy.

How do you remove moisture from plastic?

Dehumidifying Dryers are designed to eliminate moisture in the plastic material before processing. Air is forced through a desiccant bed to make it extremely dry. This air is then heated to a specified temperature and fed into a Drying Hopper containing the material to be dried.

What are the advantages of spray drying?

Benefits of Spray-Drying Some of the advantages of spray-drying include its ability to be fully automated and continuous. Short residence times and suitability for both heat-sensitive and heat-resistant foods are other advantages. The technology is suitable for a variety of feed materials, provided they are pumpable.

What is spray drying used for?

21.2 Spray Drying Spray drying is often employed in food and pharmaceutical industries for producing powder forms of various products. It involves spraying the solution containing the compounds of interest into droplets (size 10–500 μm) which are subsequently dried in hot air.

What foods can be preserved by drying?

Some fruits and vegetables suitable for drying include apples, pears, peaches, plums, apricots, bananas, cantaloupe, strawberries, blueberries, carrots, celery, corn, green beans, potatoes, and tomatoes. Fruits can also be dried as fruit leathers and rolls.
