A fluid bed dryer is used for drying powders, granules, and other solid materials by fluidizing them with hot air.

• Used in pharmaceutical, food processing, and chemical industries

• Provides uniform drying and prevents overheating

• Can be used for drying materials with different particle sizes and shapes

Resin is a sticky substance derived from plants and used for various purposes such as adhesives, coatings, and in the production of plastics.

• Resin is commonly used in the production of adhesives and coatings.

• It is also used in the manufacturing of plastics and composite materials.

• Resin can be derived from plants such as pine trees or synthesized from petrochemicals.

• Examples of resin include epoxy resin, polyurethane re

Resin is measured in kg/liter by calculating the weight of resin in kilograms and dividing it by the volume in liters.

• Resin weight in kilograms is divided by the volume in liters to get the measurement in kg/liter.

• For example, if you have 5 kg of resin in a container with a volume of 2 liters, the measurement would be 5 kg / 2 liters = 2.5 kg/liter.
